Description: Sustainability, Vol. 10, Pages 2593: Visual Analysis of the Height Ratio between Building and Background Vegetation. Two Rural Cases of Study: Spain and Sweden Sustainability doi: 10.3390/su10082593 Authors: Jacinto Garrido-Velarde María Jesús Montero-Parejo Julio Hernández-Blanco Lorenzo García-Moruno The perception of apparent sizes of buildings in a rural environment depends on the height ratio between the building and its surrounding vegetation, and it is this parameter which is currently used to assess the built landscapes. The impact of a contrasting height is less strong if the building does not exceed the horizon line. For buildings overshooting the skyline, the building’s level of sharpness and number of lines in contrast to the sky determines the impact of the scales, and vegetation in the background helps to reduce impact. The specific objectives of the present study were: (1) finding height–ratio thresholds between building and background vegetation, which may improve the integration of rural buildings in sky-sensitive locations, and; (2) comparing the results in two rural contexts with very different climatic conditions: Spain and Sweden. A survey of eighteen scenarios (nine Spanish and nine Swedish), all digitally modified with different relative height ratios between vegetation and buildings, was performed. The survey was evaluated by the public from both countries. Regardless of the country of origin, integration of the building was good or very good when the vegetation in background did not exceed one half of the height of the construction. These results may be translated to technical criteria for planning assessment.

Description: Sustainability, Vol. 10, Pages 2586: Conserving Tropical Forests: Can Sustainable Livelihoods Outperform Artisanal or Informal Mining? Sustainability doi: 10.3390/su10082586 Authors: Joshua Fisher Poonam Arora Sophia Rhee The viability of conservation efforts, including protected areas and buffer zones, depends on finding ways to make those strategies more attractive and viable for local populations. This paper presents a pilot study utilizing a rapid rural appraisal of livelihoods in the buffer zone of Tambopata National Reserve in Madre de Dios, Peru, threatened by illegal gold mining and logging. We evaluated three predominant economic activities—artisanal gold mining, Brazil nut harvesting, and fish farming—in terms of potential economic returns. The main research question we ask is whether the latter two potentially sustainable land uses can match or exceed the returns from mining. Contrary to popular belief, we find that enhancing value creation at product origin could make existing forest-friendly livelihoods as or more lucrative than extractive ones. This has implications on local conservation policy encouraging implementable strategies incentivizing sustainable livelihoods in tandem with, and in support of, conservation goals.

Description: Sustainability, Vol. 10, Pages 2601: Researcher–Planner Dialogue on Environmental Justice and Its Knowledges—A Means to Encourage Social Learning Towards Sustainability Sustainability doi: 10.3390/su10082601 Authors: Aino Rekola Riikka Paloniemi Societies aiming for a sustainable future need more effective and legitimate planning and decision making practices, in which various actors together find pathways towards a sustainable transition. In this paper, we approach sustainability and environmental justice as epistemological (and ontological) challenges for land-use planning, and empirically analyse how action research could support planners’ social learning and planning towards fair and sustainable development. We analysed qualitatively the evolution of the researcher–planner dialogue while co-designing and developing better methods, means and practices to improve environmental justice in regional scale planning in Kymenlaakso Region, South-East Finland. We found that researcher-planner dialogue developed during cooperation. While in the beginning, social learning related to approaching environmental justice as a fair distribution of power evolved incrementally, later, when dialogue became more focused, communicative and reflective as an outcome of mutual frames and trust, learning occurred in a more transformative way. Such transformative learning concerned recognising youth as a silent group in the planning process and the means to involve their perceptions in planning. In order to support sustainability transformation in the future, we conclude that it is essential to create opportunities for such incremental and transformative social learning through innovative modes of interaction in various contexts.

Description: Sustainability, Vol. 10, Pages 2602: Towards a Joint Local Energy Transition Process in Urban Districts: The GO2Zero Simulation Game Sustainability doi: 10.3390/su10082602 Authors: Geertje Bekebrede Ellen van Bueren Ivo Wenzler The depletion of fossil fuel sources for our energy system and the influence on overall CO2 emissions drive the need to more sustainable energy systems. The transition towards a renewable energy system cannot be seen as a purely technical issue; it is strongly embedded within society. In this study, we analyze the stakeholder complexities of the transition in urban districts and research the use of a simulation game to increase the understanding of the complexity of the transition. Surveys and observations were used to collect data about the learning experiences of playing the game GO2Zero. The results show that participants liked to play the game and they considered the game a valid representation of the system. Further, the participants agree that they obtained a better understanding of the complexity of the residential energy system and experienced a variety of challenges in the transition. Simulation games, like GO2Zero, could become valuable instruments in local energy transition processes as they offer a safe environment for novices and experts to jointly experiment with the challenges in this process. These experiences could support the design of the transition process by helping actors to formulate goals and collaborative strategies for achieving those goals. Future research will focus on the use of this game for experimenting with different strategies and instruments and to analyze their effects.

Description: Sustainability, Vol. 10, Pages 2613: An E-Commerce Platform for Industrialized Construction Procurement Based on BIM and Linked Data Sustainability doi: 10.3390/su10082613 Authors: Dandan He Zhongfu Li Chunlin Wu Xin Ning Industrialized construction has raised the requirements of procurement methods used in the construction industry. The rapid development of e-commerce offers efficient and effective solutions, however the large number of participants in the construction industry means that the data involved are complex, and problems arise related to volume, heterogeneity, and fragmentation. Thus, the sector lags behind others in the adoption of e-commerce. In particular, data integration has become a barrier preventing further development. Traditional e-commerce platform, which considered data integration for common product data, cannot meet the requirements of construction product data integration. This study aimed to build an information-integrated e-commerce platform for industrialized construction procurement (ICP) to overcome some of the shortcomings existing platforms. We proposed a platform based on Building Information Modelling (BIM) and linked data, taking an innovative approach to data integration. It uses industrialized construction technology to support product standardization, BIM to support procurement process, and linked data to connect different data sources. The platform was validated using a case study. With the development of an e-commerce ontology, industrialized construction component information was extracted from BIM models and converted to Resource Description Framework (RDF) format. Related information from different data sources was also converted to RDF format, and Simple Protocol and Resource Description Framework Query Language (SPARQL) queries were implemented. The platform provides a solution for the development of e-commerce platform in the construction industry.

Description: Sustainability, Vol. 10, Pages 2614: An Efficient Grid-Based K-Prototypes Algorithm for Sustainable Decision-Making on Spatial Objects Sustainability doi: 10.3390/su10082614 Authors: Hong-Jun Jang Byoungwook Kim Jongwan Kim Soon-Young Jung Data mining plays a critical role in sustainable decision-making. Although the k-prototypes algorithm is one of the best-known algorithms for clustering both numeric and categorical data, clustering a large number of spatial objects with mixed numeric and categorical attributes is still inefficient due to complexity. In this paper, we propose an efficient grid-based k-prototypes algorithm, GK-prototypes, which achieves high performance for clustering spatial objects. The first proposed algorithm utilizes both maximum and minimum distance between cluster centers and a cell, which can reduce unnecessary distance calculation. The second proposed algorithm as an extension of the first proposed algorithm, utilizes spatial dependence; spatial data tends to be similar to objects that are close. Each cell has a bitmap index which stores the categorical values of all objects within the same cell for each attribute. This bitmap index can improve performance if the categorical data is skewed. Experimental results show that the proposed algorithms can achieve better performance than the existing pruning techniques of the k-prototypes algorithm.

Description: Sustainability, Vol. 10, Pages 2609: The Influence of the Backfilling Roadway Driving Sequence on the Rockburst Risk of a Coal Pillar Based on an Energy Density Criterion Sustainability doi: 10.3390/su10082609 Authors: Yi Xue Zhengzheng Cao Feng Du Lin Zhu The rockburst hazard has always been an important issue affecting the safety production of coal mines in China. The unreasonable sequencing of roadway driving can lead to the dynamic instability of coal pillars, which subsequently causes rockburst accidents in roadway backfilling mining engineering and poses a serious threat to the safety of the mines. Roadway backfilling mining technology is an effective approach with which to mine corner residual coal resources under buildings, railways, and rivers. An energy density criterion is established and programmed with FISH language using numerical analysis software for the rockburst risk evaluation of coal pillars. On this basis, a numerical simulation model is established based on four scheme types, namely, the sequential mining, one-roadway interval mining, two-roadway interval mining, and three-roadway interval mining schemes. The influence of the backfilling roadway driving sequence on coal pillar stability is investigated, and the change law of vertical stress and energy density factor of coal pillars in different driving sequences in roadway backfilling mining technology are analyzed. According to the research results, the maximum energy density factor value of 21,172 J/m4 for coal pillars in one-roadway interval mining is the lowest among the different schemes. Therefore, the one-roadway interval mining scheme is the optimal choice in roadway backfilling mining technology. The results can be treated as an important basis for the prevention and treatment of coal pillar instability and rockburst in roadway backfilling mining technology.

Description: Sustainability, Vol. 10, Pages 2604: Analysis of Guidelines and Identification of Characteristics Influencing the Deconstruction Potential of Buildings Sustainability doi: 10.3390/su10082604 Authors: Roberta Carvalho Machado Henor Artur de Souza Gustavo de Souza Veríssimo Growing concerns regarding environmental preservation and the fact that the construction industry is one of the sectors with the highest rates of resource consumption and waste generation, have encouraged the adoption of deconstruction as an alternative to the demolition of buildings at the end of their lifecycle. However, the choice of strategies to enable deconstruction requires an in-depth knowledge of how the building’s characteristics, combined with the procedures adopted in the deconstruction process, will affect the reutilization of materials and components. In this paper, characteristics relating to design for deconstruction (DfD) are identified and the influence of each characteristic on the viability of a deconstruction is analysed. A literature review is conducted to assess the guideline of DfD and to identify relevant characteristics. These characteristics are then divided into the following categories: direct influence enabling deconstruction; influence on the ease of the process; and, influence on prolonging a building’s lifecycle. A number of questions are suggested for analysing each characteristic, and these can be employed in the development of a methodology for evaluating a building’s deconstruction potential. The identification of characteristics involved in the deconstruction guidelines may assist in the optimization of projects and the planning of deconstruction processes.

Description: Sustainability, Vol. 10, Pages 2605: Building a More Sustainable Society? A Case Study on the Role of Sustainable Development in the Education and Early Career of Water and Environmental Engineers Sustainability doi: 10.3390/su10082605 Authors: Anu Vehmaa Meeri Karvinen Marko Keskinen Engineering education is critical for sustainability, given the key role that engineers have in shaping the development of our society. Yet, engineering studies have traditionally not been driven by sustainability-related knowledge and skills, but focused more on general computational skills and technical problem-solving. This has also been the case in our case study, which focuses on recent water and environmental engineering graduates in Finland. We studied the role that sustainable development has had in their education and early career through an extensive questionnaire and semi-structured interviews. The analysis was done in two ways: indirectly by comparing how well the key working life knowledge and skills recognized by the respondents correspond with sustainability-related skills, and directly by studying the graduates’ views towards the sustainable development and their possibilities to advance it in their work. The results show that although sustainability was not at the core of respondents’ studies, their key competencies correspond well with sustainability-related working life skills. The respondents also see that sustainable development has a central role in water and environmental engineering, although it is typically more visible at a strategic rather than a practical level. However, the results also indicate that several early-career engineers have deficient knowledge of sustainable development, and are therefore lacking the ability to fully connect the principles of sustainable development into their own expertise. Overall, the findings suggest that water and environmental engineers with their wide set of competencies have the potential to take on a larger role in building a more sustainable society. To ensure this, engineering education should emphasize the connection between the field and sustainable development and clearly link engineers’ core competencies with the skills required to promote sustainability.

Description: Sustainability, Vol. 10, Pages 2603: Historic Urban Landscapes: A Review on Trends and Methodologies in the Urban Context of the 21st Century Sustainability doi: 10.3390/su10082603 Authors: Arturo Azpeitia Santander Agustín Azkarate Garai-Olaun Ander de la Fuente Arana This article makes a critical reflection, questioning the notion of historical urban landscapes as a conceptual paradigm used for the basis of urban conservation in the twenty-first century. The study begins with a brief summary of the origins and subsequent evolution of this concept, highlighting the two key reference milestones: the Vienna Memorandum (UNESCO, 2005) and the Paris Recommendation (UNESCO, 2011). Subsequently, the focus of attention will be on highlighting the problems and difficulties posed by the management and protection of historic urban landscapes today. In this sense, the focus of attention will be placed on the assumption that change is an inherent part of the urban condition, since there is no consensus on what the limits of acceptable change in historic urban landscapes should be. It also emphasizes three factors that make this more difficult: (1) the reminiscences of the doctrines of the Weberian administration in the current models of government; (2) the subjective nature of the systems of indicators applied to the scope of historic cities; and (3) the opportunism of tactical urbanism, which, despite its shortcomings, is becoming an outstanding alternative for the methodological development of the historic urban landscapes.

Description: Sustainability, Vol. 10, Pages 2633: Scenario-Based Simulation of Tianjin City Using a Cellular Automata–Markov Model Sustainability doi: 10.3390/su10082633 Authors: Ruci Wang Hao Hou Yuji Murayama Rapid urbanization is occurring throughout China, especially in megacities. Using a land use model to obtain future land use/cover conditions is an essential method to prevent chaotic urban sprawl and imbalanced development. This study utilized historical Landsat images to create land use/cover maps to predict the land use/cover changes of Tianjin city in 2025 and 2035. The cellular automata–Markov (CA–Markov) model was applied in the simulation under three scenarios: the environmental protection scenario (EPS), crop protection scenario (CPS), and spontaneous scenario (SS). The model achieved a kappa value of 86.6% with a figure of merit (FoM) of 12.18% when compared to the empirical land use/cover map in 2015. The results showed that the occupation of built-up areas increased from 29.13% in 2015 to 38.68% (EPS), 36.18% (CPS), and 47.94% (SS) in 2035. In this context, current urbanization would bring unprecedented stress on agricultural resources and forest ecosystems, which could be attenuated by implementing protection policies along with decelerating urban expansion. The findings provide valuable information for urban planners to achieve sustainable development goals.

Description: Sustainability, Vol. 10, Pages 2629: Pathways to Coastal Resiliency: The Adaptive Gradients Framework Sustainability doi: 10.3390/su10082629 Authors: Elisabeth M. Hamin Yaser Abunnasr Max Roman Dilthey Pamela K. Judge Melissa A. Kenney Paul Kirshen Thomas C. Sheahan Don J. DeGroot Robert L. Ryan Brain G. McAdoo Leonard Nurse Jane A. Buxton Ariana E. Sutton-Grier Elizabeth A. Albright Marielos Arlen Marin Rebecca Fricke Current and future climate-related coastal impacts such as catastrophic and repetitive flooding, hurricane intensity, and sea level rise necessitate a new approach to developing and managing coastal infrastructure. Traditional “hard” or “grey” engineering solutions are proving both expensive and inflexible in the face of a rapidly changing coastal environment. Hybrid solutions that incorporate natural, nature-based, structural, and non-structural features may better achieve a broad set of goals such as ecological enhancement, long-term adaptation, and social benefits, but broad consideration and uptake of these approaches has been slow. One barrier to the widespread implementation of hybrid solutions is the lack of a relatively quick but holistic evaluation framework that places these broader environmental and societal goals on equal footing with the more traditional goal of exposure reduction. To respond to this need, the Adaptive Gradients Framework was developed and pilot-tested as a qualitative, flexible, and collaborative process guide for organizations to understand, evaluate, and potentially select more diverse kinds of infrastructural responses. These responses would ideally include natural, nature-based, and regulatory/cultural approaches, as well as hybrid designs combining multiple approaches. It enables rapid expert review of project designs based on eight metrics called “gradients”, which include exposure reduction, cost efficiency, institutional capacity, ecological enhancement, adaptation over time, greenhouse gas reduction, participatory process, and social benefits. The framework was conceptualized and developed in three phases: relevant factors and barriers were collected from practitioners and experts by survey; these factors were ranked by importance and used to develop the initial framework; several case studies were iteratively evaluated using this technique; and the framework was finalized for implementation. The article presents the framework and a pilot test of its application, along with resources that would enable wider application of the framework by practitioners and theorists.

Description: Sustainability, Vol. 10, Pages 2627: Photovoltaic Power Forecasting Based on EEMD and a Variable-Weight Combination Forecasting Model Sustainability doi: 10.3390/su10082627 Authors: Hui Wang Jianbo Sun Weijun Wang It is widely considered that solar energy will be one of the most competitive energy sources in the future, and solar energy currently accounts for high percentages of power generation in developed countries. However, its power generation capacity is significantly affected by several factors; therefore, accurate prediction of solar power generation is necessary. This paper proposes a photovoltaic (PV) power generation forecasting method based on ensemble empirical mode decomposition (EEMD) and variable-weight combination forecasting. First, EEMD is applied to decompose PV power data into components that are then combined into three groups: low-frequency, intermediate-frequency, and high-frequency. These three groups of sequences are individually predicted by the variable-weight combination forecasting model and added to obtain the final forecasting result. In addition, the design of the weights for combination forecasting was studied during the forecasting process. The comparison in the case study indicates that in PV power generation forecasting, the prediction results obtained by the individual forecasting and summing of the sequences after the EEMD are better than those from direct prediction. In addition, when the single prediction model is converted to a variable-weight combination forecasting model, the prediction accuracy is further improved by using the optimal weights.

Description: Sustainability, Vol. 10, Pages 2622: A Rough Multi-Criteria Decision-Making Approach for Sustainable Supplier Selection under Vague Environment Sustainability doi: 10.3390/su10082622 Authors: Huiyun Lu Shaojun Jiang Wenyan Song Xinguo Ming With the growing awareness of environmental and social issues, sustainable supply chain management (SSCM) has received considerable attention both in academia and industry. Supplier selection plays an important role in the successful implementation of sustainable supply chain management, because it can influence the performance of SSCM. Sustainable supplier selection is a typical multi-criteria decision-making problem involving subjectivity and vagueness. Although some previous researches of supplier selection use fuzzy approaches to deal with vague information, it has been criticized for requiring much priori information and inflexibility in manipulating vagueness. Moreover, the previous methods often omit the environmental and social evaluation criteria in the supplier selection. To manipulate these problems, a new approach based on the rough set theory and ELECTRE (ELimination Et Choix Traduisant la REalité) is developed in this paper. The novel approach integrates the strength of rough set theory in handling vagueness without much priori information and the merit of ELECTRE in modeling multi-criteria decision-making problem. Finally, a case study of sustainable supplier selection for solar air-conditioner manufacturer is provided to demonstrate the application and potential of the approach.

Description: Sustainability, Vol. 10, Pages 2624: Economic Transition and Changing Location of Manufacturing Industry in China: A Study of the Yangtze River Delta Sustainability doi: 10.3390/su10082624 Authors: Jiawei Wu Yehua Dennis Wei Qizhai Li Feng Yuan Industrial restructuring is widely considered an important force in regional economic growth and sustainable development. With increased globalization and economic transition, a dramatic industrial restructuring has been taking place in China. Applying geographically weighted shift-share model (GW-SSM) and geographically and temporally weighted regression model (GTWR), we analyze (re)location dynamics and determinants of the manufacturing industry in the Yangtze River Delta (YRD) from 1999 to 2013, with particular attention to the implications of economic transition and institutional restructuring. We find that high-tech and capital-intensive manufacturing industries agglomerated in coastal cities, while labor-intensive and resource-based sectors have become spatially more dispersed to peripheral areas. We also find that the development of service and high-tech industries, rising labor costs, and more strict environmental regulations have facilitated the geographic dispersion of labor- and pollution-intensive industries. Moreover, regions with advantages in intermediate goods, preferential policies, and urbanization economies are attractive to capital- and technology-intensive manufacturing industries. Our research suggests that development policies should be tailored to specific regions to promote local production and innovative networks and make manufacturing industries more competitive.

Description: Sustainability, Vol. 10, Pages 2621: Adoption of Conservation Tillage on the Semi-Arid Loess Plateau of Northwest China Sustainability doi: 10.3390/su10082621 Authors: Qingfeng Han Kadambot H. M. Siddique Fengmin Li Conservation tillage is an important approach to prevent water loss and soil erosion and promote soil fertility that has been adopted widely throughout the world. However, despite promotion of the benefits of conservation tillage, obstacles are still encountered in some regions. A survey of 385 farmer households in the semi-arid Loess Plateau of China was conducted to assess the adoption of conservation tillage (ACT). This investigation was located in two counties that have run conservation tillage demonstrations with wheat for at least eight years. A binary logistic regression model was used to quantify the factors determining whether or not farmers adopt conservation tillage. Farmer’s education level, the influence of training, and field demonstrations by agricultural departments had significant positive effects on ACT. Although the adoption rate of conservation tillage in this paper was very high (89%), farmers were reluctant to continue practicing conservation tillage based on their experiences, which is contrary to the expectations of the government. The area available for planting winter wheat and the number of arable plots per household also had significant positive effects on ACT. However, the total cultivated area of land per household had a significant negative impact on ACT. Farmer awareness of conservation tillage technology, the distance from a farmer’s house to the nearest agricultural market, and the size of the active labor force in the family had significant negative impacts on ACT. These results will help in the development of more effective and targeted policies to improve the sustainability of farming systems on the semi-arid Loess Plateau.

Description: Sustainability, Vol. 10, Pages 2620: Transition towards Energy Efficiency: Developing the Nigerian Building Energy Efficiency Code Sustainability doi: 10.3390/su10082620 Authors: Susanne Geissler Doris Österreicher Ene Macharm In Nigeria, there is an estimated deficit of 17 million housing units. Power supply is insufficient, and the electricity supply for about 60 million Nigerians relies on private generators, causing noise, pollution, and high expenditures for mainly imported fuel. Altogether, current challenges clearly demonstrate the need for effective energy efficiency policies targeting also the building sector. The Nigerian Energy Support Program began in 2013, among others, with the objective being to support the Nigerian Government in developing the Nigerian Building Energy Efficiency Code. This paper presents two preparatory activities carried out in order to come up with suggestions for a legal framework well suited for the situation on the ground: the Case Study Building Analysis carried out in collaboration with a Nigerian developer and the Nigerian Building Energy Efficiency Guideline, elaborated together with stakeholders. The results of preparatory activities pointed out that the code must put emphasis on climate adaptive design and must define requirements and procedures in a clear and simple way to allow for effective enforcement. Only then can energy-efficient mass housing be feasible in Nigeria. The paper concludes with a description of the Nigerian Building Energy Efficiency Code (BEEC), officially approved and launched by the Federal Minister of Power, Works and Housing on 29 August 2017.

Description: Sustainability, Vol. 10, Pages 2619: Are the World-Leading Primary Silver Mines Exhausting? Sustainability doi: 10.3390/su10082619 Authors: Marcello Ruberti Stefania Massari Silver is one of the rarest metals in nature and certainly among the most used ones, not only as precious good for financial investments but also for many industrial critical applications. Because it would be very difficult to analyze the situation regarding the future global availability of silver as a commodity in general, due to the necessity of a large amount of data which are hardly available, we have focused only on the mining production of primary silver. In particular, the study regards the activities of a sample consisting of twelve of the world top fifteen leading primary silver mines, which represent the 54% of the worldwide primary silver production and 16% of the global silver mining production. We have investigated the related exploitation state and trends of these twelve sites by elaborating their last ten-years statistics on silver production, ore grades, resources and reserves. The findings of this study, in short, are that the cumulative average silver ore grades, both in extracted mineral, resources and reserves, of the above selected mines, have decreased and also that the new mining fields (Dukat, San Bartolomé, Pirquitas, Saucito) have lower silver content indexes than the older ones.

Description: Sustainability, Vol. 10, Pages 2617: Exploring Twitter for CSR Disclosure: Influence of CEO and Firm Characteristics in Latin American Companies Sustainability doi: 10.3390/su10082617 Authors: Yuli Marcela Suárez-Rico Mauricio Gómez-Villegas María Antonia García-Benau Social networks, which are characterised by accessibility and interactivity, offer great potential for dialogue between companies and stakeholders, for example as platforms for publishing information on aspects of corporate social responsibility (CSR). In this paper, we use a synthetic index to analyse levels of CSR disclosure via Twitter, and identify explanatory variables of this disclosure by studying the demographic characteristics of the Chief Executive Officer (CEO) and of the company. This synthetic index was based on data for 93 companies located in the four countries of the Pacific Alliance (Chile, Colombia, Mexico, and Peru), using categories based on the 2016 Global Reporting Initave (GRI) Standards. The tweets were compiled during a period of two months in 2017, immediately before and after the publication of each CSR report. The synthetic index was taken as the dependent variable and used as the basis for multivariate regression analysis to identify the relationship between the level of CSR disclosure on Twitter and the characteristics of the firm and its CEO. The results obtained show that firms operating in environmentally-sensitive industries present higher levels of CSR disclosure on Twitter than those in other sectors. By country of origin, the Colombian and Chilean companies offered higher levels of disclosure than those in Mexico and Peru. The regression analysis revealed a positive relationship between the firm operating in a sensitive industry and its level of CSR disclosure on Twitter, and an inverse relationship between the latter variable and the tenure of the CEO.

Description: Sustainability, Vol. 10, Pages 2659: Research on the Influence of Real Estate Development on Private Investment: A Case Study of China Sustainability doi: 10.3390/su10082659 Authors: Jiangtao Li Jianyue Ji Huiwen Guo Lei Chen Private investment in China, as a developing country, is an important source of financing for Chinese SMEs (Small and Medium-Size Enterprises) and has played a major role in the development of the real economy. However, in 2016, the growth rate of private investment in China dropped from 10.18% to 3.17%, which had a significant impact on the real economy. At the same time, China’s real estate market has developed rapidly, attracting a large number of capital inflows. The relationship between real estate development and private investment in China is worth considering. This study first, theoretically analyzes the influence mechanism of real estate industry on private investment, pointing out that within a modest development range, the development of real estate industry can promote private investment through the industrial linkage, urbanization, and balance sheet effects, but when real estate is overdeveloped, it has an inhibitory effect on private investment through vampire effect, raising costs and reducing demand effect. In other words, real estate has different effects on private investment in different developmental periods. Therefore, there is a non-linear relationship between the two variables. Second, the relevant provincial panel data of 31 provinces in mainland China from 2003 to 2015 were selected. Using the dynamic panel system Generalized Method of Moments (GMM), this study estimated the correlation between real estate development and private investment. The empirical results showed that the development of the real estate industry has a significant impact on the level of private investment; the two showing an “inverted U-shaped” relationship. At present, in some provinces in China, the real estate industry has exceeded the inverted U-shaped threshold. To boost the vitality of private investment in promoting real economic growth, the development of the real estate industry should be restricted, and house prices should be properly regulated.

Description: Sustainability, Vol. 10, Pages 2657: Numerical Thermal Characterization and Performance Metrics of Building Envelopes Containing Phase Change Materials for Energy-Efficient Buildings Sustainability doi: 10.3390/su10082657 Authors: Mingli Li Guoqing Gui Zhibin Lin Long Jiang Hong Pan Xingyu Wang Residential and commercial buildings consume nearly 40 percent of total USA energy use and account for one-third of total greenhouse gas emissions. The challenges are how to effectively promote energy efficiency in buildings to respond to the high financial burden of energy consumption, while reducing pollution. Phase change materials (PCMs) have been used as passive energy storage for building systems. Along this vein, this study aims to numerically elucidate the design parameters of building envelopes strengthened by PCM layers, and unveil their impacts on building energy efficiency. Critical design variables, such as the thickness of the PCM layer, the latent heat of PCMs, or melting temperature of PCMs were selected for a parametric study, while performance metrics were used to assess building efficiency. Results revealed that PCM-enabled building walls exhibited different levels of improvement, in terms of reduction of peak temperature and temperature swings. Among the variables, the selection of the proper melting point for a PCM was identified as the most crucial parameter for determining building energy efficiency, while the heat of fusion was also observed as a critical property of PCM for building potential. Findings also demonstrated that the placement of the PCM near the interior wall surface could achieve higher efficiency, as compared to other cases. Results also showed that the thermal conductivity of PCM has a minimum contribution to energy storage capacity.

Description: Sustainability, Vol. 10, Pages 2655: Substructure Hybrid Simulation Boundary Technique Based on Beam/Column Inflection Points Sustainability doi: 10.3390/su10082655 Authors: Zaixian Chen Xueyuan Yan Hao Wang Xingji Zhu Billie F. Spencer Compatibility among substructures is an issue for hybrid simulation. Traditionally, the structure model is regarded as the idealized shear model. The equilibrium and compatibility of the axial and rotational direction at the substructure boundary are neglected. To improve the traditional boundary technique, this paper presents a novel substructure hybrid simulation boundary technique based on beam/column inflection points, which can effectively avoid the complex operation for realizing the bending moment at the boundary by using the features of the inflection point where the bending moment need not be simulated in the physical substructure. An axial displacement prediction technique and the equivalent force control method are used to realize the proposed method. The numerical simulation test scheme for the different boundary techniques was designed to consider three factors: (i) the different structural layers; (ii) the line stiffness ratio of the beam to column; and (iii) the peak acceleration. The simulation results for a variety of numerical tests show that the proposed technique shows better performance than the traditional technique, demonstrating its potential in improving HS test accuracy. Finally, the accuracy and feasibility of the proposed boundary technique is verified experimentally through the substructure hybrid simulation tests of a six-story steel frame model.

Description: Sustainability, Vol. 10, Pages 2666: Understanding the Spontaneous Spreading of Stone Bunds in Ethiopia: Implications for Sustainable Land Management Sustainability doi: 10.3390/su10082666 Authors: Meskerem Abi Aad Kessler Peter Oosterveer Degefa Tolossa This study deals with the spontaneous spreading of stone bunds in the central Ethiopian highlands, i.e., the adoption and implementation of stone bunds by farmers on their own initiative. The study tests the hypothesis that spontaneously implemented stone bunds, as compared to stone bunds implemented by mass mobilization campaigns, are more integrated with other land management practices and lead to higher yields. Data are collected in the Girar Jarso woreda through field observations and household surveys. Descriptive statistics are used to analyze and test the data at 1% and 5% probability levels. Results show that stone bunds are spontaneously implemented mainly on farmlands located nearby the homesteads where farmers perceive severe erosion, poor soil fertility and steep slope gradients. Compared to stone bunds implemented by mass mobilization, spontaneously implemented stone bunds are perceived as better maintained, more frequently modified to fit the farming system and better integrated with soil fertility management practices, such as applying fertilizer, compost and manure. Particularly, this better integration with other practices is very important, because it makes stone bunds more effective in reducing erosion, leading to beneficial effects on soil moisture and soil productivity, as perceived by farmers. The study, therefore, suggests that the mass mobilization campaign should use a more participatory and integrated approach, in which there is ample space for awareness raising and learning concerning the benefits of integrated farm management, and in which farmers themselves have a leading role in the decision on where to construct stone bunds. Such a strategy will lead to more sustainable impact on soil fertility and food security than the current top-down intervention approach.

Description: Sustainability, Vol. 10, Pages 2674: Reputation Effects in Socially Driven Sharing Economy Transactions Sustainability doi: 10.3390/su10082674 Authors: Maarten ter Huurne Amber Ronteltap Chenhui Guo Rense Corten Vincent Buskens Reputation has often been proposed as the central mechanism that creates trust in the sharing economy. However, some sharing platforms that focus primarily on social rather than economically driven exchanges have managed to facilitate exchanges between users without the use of a reputation system. This could indicate that socially driven exchanges are in less need of reputation systems and that having sufficient trust is less problematic. We examine the effect of seller reputation on sales and price as proxies for trust, using a large dataset from a Dutch meal-sharing platform. This platform aims to stimulate social interactions between people via meal sharing. Multilevel regression analyses were used to test the association of reputation with trust. Our main empirical results are that reputation affects both sales and price positively, consistent with the existing reputation literature. We also found evidence of the presence of an information effect, i.e., the influence of reputation on sharing decreases when additional profile information is provided (e.g., a profile photo, a product description). Our results thus confirm the effectiveness of reputation in more socially driven exchanges also. Consequently, platform owners are advised to use reputation on their platform to increase sharing between its users.

Description: Sustainability, Vol. 10, Pages 2676: Measuring Social Vulnerability to Flood Disasters in China Sustainability doi: 10.3390/su10082676 Authors: Ming Zhang Wenbo Xiang Meilan Chen Zisen Mao To proactively prevent losses from flood disasters and subsequent potential human conflicts, it is critical to measure the social vulnerability of a country or a region to flood. In this article, we first propose a list of potential indicators for measuring this social vulnerability. These indicators’ significances are then tested based on their correlation coefficients with a vulnerability index obtained using nonparametric Data Envelopment Analysis. In the final measurement system, there are nine indicators: the proportion of the primary industry, infrastructure development level, income gap between urban and rural residents, the proportion of population over 60 years old, the proportion of children under 14 years old, the number of people receiving minimum income assistance, and the number of disasters per year. We then conduct principal component analysis to evaluate the social vulnerability level. Our results show that the social vulnerability level is mostly impacted by the economic principal component and the demographic and social security principal component. Moreover, our results also confirm that the social vulnerability level to flood in China declined overall from 2003 to 2015.

Description: Sustainability, Vol. 10, Pages 2673: The Public Willingness to Pay for Reducing the Incidence of Hazardous Chemical Spill Accidents by Half in South Korea Sustainability doi: 10.3390/su10082673 Authors: Hye-Jeong Lee Hyo-Jin Kim Seung-Hoon Yoo Hazardous chemical spill (HCS) accidents, which occur due to careless workers, transport accidents, etc., can be harmful to humans. Recently, an average of 96 cases of HCS accidents have taken place in South Korea annually. As a result, the government is trying to reduce the incidence of HCS accidents by 50%. Government officials are seeking information about the value that the enforcement of the reduction plan will bring for the public. This knowledge will help government officials decide whether to implement the reduction plan. This article seeks to acquire information about the public willingness to pay (WTP) for the reduction plan, employing the contingent valuation (CV) technique. For this purpose, a total of 1000 households living in South Korea participated in the CV survey in 2017. The data on the WTP were gathered using a dichotomous choice question and analyzed using the spike model. Forty-five percent of the respondents were willing to accept an increase in income taxes to carry out the reduction plan. The mean household WTP estimate was obtained as KRW 3830 (USD 3.41) per annum. The national value expanded from the sample to the population is worth KRW 74.8 billion (USD 66.6 million) per year. This value implies the public value of the reduction plan and can be applied in policy analysis and decision-making concerning the reduction of the incidence of HCS accidents.

Description: Sustainability, Vol. 10, Pages 2671: The Sustainable Characteristic of Bio-Bi-Phase Flow of Peristaltic Transport of MHD Jeffrey Fluid in the Human Body Sustainability doi: 10.3390/su10082671 Authors: Ahmed Zeeshan Nouman Ijaz Tehseen Abbas Rahmat Ellahi This study deals with the peristaltic transport of non-Newtonian Jeffrey fluid with uniformly distributed identical rigid particles in a rectangular duct. The effects of a magnetohydrodynamics bio-bi-phase flow are taken into account. The governing equations for mass and momentum are simplified using the fact that wavelength is much greater than the amplitude and small Reynolds number. A closed-form solution for velocity is obtained by means of the eigenfunction expansion method whereby pressure rise is numerically calculated. The results are graphically presented to observe the effects of different physical parameters and the suitability of the method. The results for hydrodynamic, Newtonian fluid, and single-phase problems can be respectively obtained by taking the Hartmann number (M = 0), relaxation time (λ1=0), and volume fraction (C = 0) as special cases of this problem.

Description: Sustainability, Vol. 10, Pages 2591: Reducing Seismic Vulnerability and Energy Demand of Cities through Green Infrastructure Sustainability doi: 10.3390/su10082591 Authors: Riccardo Privitera Daniele La Rosa Historically, urbanization processes in Italy resulted in built environments with high levels of seismic vulnerability, low energy efficiency and a lack of green spaces. The latter represent the main providers of ecosystem services in cities and play a relevant role in reducing the effects of climate change by the regulation of microclimate and urban heat islands that are responsible for building energy consumption. Despite their importance in providing ecosystem services, the implementation of green infrastructure challenges limited financial resources for the public acquisition of private plots. This paper proposes a strategy to implement an urban green infrastructure aimed at generating a double positive effect on cities by triggering seismic retrofitting and the reduction of cooling energy demand of the existing urban fabric. This is proposed through a transfer of development rights program where landowners gain economic incentives to adopt seismic retrofitting interventions and, at the same time, public administrations implement the green infrastructure in the portion of areas transferred to the municipality. The energy efficiency of buildings closer to the green infrastructure, therefore, benefits from the cooling effects of this new greenery. The strategy is tested under different scenarios of acquisition of private land by public administrations in the metropolitan area of Catania (Italy).

Description: Sustainability, Vol. 10, Pages 2588: Identifying Economic Growth Convergence Clubs and Their Influencing Factors in China Sustainability doi: 10.3390/su10082588 Authors: Feng Li Guangdong Li Weishan Qin Jing Qin Haitao Ma Balanced and coordinated economic development across regions is a critical goal of regional economic development and new-type urbanization in China. However, few studies have examined economic growth convergence clubs at the county level. To extend the research on convergence clubs, this research applies a log t convergence test and a dynamic spatial ordered probit model (DSOP) to endogenously identify economic growth convergence clubs in counties and to examine the influence of initial states and structures on club convergence probability. The study sample covers 2286 counties of China from 1992 to 2010. The results show significant convergence club patterns at the county levels, resulting in the gradual formation of six convergence clubs. The DSOP estimation results show that per capita fixed assets, population density, and industrialization have promoted convergence club formation to varying degrees.

Description: Sustainability, Vol. 10, Pages 2594: Resilient Entrepreneurship among European Higher Education Graduates Sustainability doi: 10.3390/su10082594 Authors: Ana-Maria Zamfir Cristina Mocanu Adriana Grigorescu Resilience represents the ability of systems and individuals to adapt and overcome the difficulties and challenges they face. Resilient entrepreneurs are those who cope with stressful or adverse situations by relying on both internal and external factors. This article examines the way higher education graduates express entrepreneurial resilience in various national contexts. We analyze the Research into Employment and professional Flexibility (REFLEX) data set that provides information on early career of higher education graduates leaving education in the academic year 1999/2000 in 13 European countries. We study resilience in entrepreneurship by considering both how long higher education graduates succeed to remain in self-employment and the extent to which they re-entry in entrepreneurship after exiting. Survival analyses, logistic and cox regressions indicate important differences in patterns of starting, remaining and returning in self-employment and in factors influencing the retention in entrepreneurship among higher education graduates. It is argued that structural factors, personal characteristics and educational background explain a large amount of variation in resilient entrepreneurship.

Since the number of containers on one- and multi-node systems is growing, knowledge about the energy consumption behavior of single web-service containers is essential in order to save energy and, of course, money. In this article, we are going to show how the energy consumption behavior of single containerized web services/web apps changes while creating replicas of the service in order to scale and balance the web service.

Description: Sustainability, Vol. 10, Pages 2699: A Framework for Regional Ecological Risk Warning Based on Ecosystem Service Approach: A Case Study in Ganzi, China Sustainability doi: 10.3390/su10082699 Authors: Tian Dong Weihua Xu Hua Zheng Yang Xiao Lingqiao Kong Zhiyun Ouyang Worldwide, most ecosystem services have declined. However, the theoretical and analytical frameworks for the ecological risk assessment of ecosystem services are still lacking. Here a framework for the risk assessment of ecosystem services was developed based on the formation, changes, risk, and management of ecosystem services. The framework was tested in Ganzi, the upstream area of the Yangtze River Basin, for the regional ecological warning of ecosystem services. Ecosystem services in the form of soil retention and sandstorm prevention and ecological risks including soil and wind erosion were modelled. The results showed that with the increase in area and quality of natural vegetation (forest and grassland), the soil retention service and sandstorm prevention service increased by 66.92% and 8.59% between 2000 and 2015, respectively. Correspondingly, the ecological risk of soil erosion decreased by 8.8%, and wind erosion remained stable. Despite the negative impacts from agricultural development on sandstorm prevention, the increase in vegetation and improvement in ecological quality led to a decrease in the ecological risks of soil erosion and sandstorm erosion by improvement of ecosystem services. This research provides a new perspective for ecological risk assessment, as well as direct management information on ecological risks, by incorporating ecosystem services.

Description: Sustainability, Vol. 10, Pages 2730: Regime-Switching Determinants for Spreads of Emerging Markets Sovereign Credit Default Swaps Sustainability doi: 10.3390/su10082730 Authors: Ma Deng Ho Tsai Using the Markov regime switching approach, we investigate the dependency of short term sovereign credit default swap (SCDS) spread changes on a nation’s country-specific fundamental factors, local, regional and macroeconomic global factors. We find that the significance of the determinants of SCDS spread changes differ across the two states of our regime-switching model. Specifically, in the good state, the weekly SCDS spread changes are mainly determined by local, regional and fundamental factors; whereas global variables have a stronger influence in the bad regime. In particular, US market returns play a dominant role in influencing the SCDS spread change in the bad state suggesting loss aversion and flight–to–quality behavior of investors. We then examine the cross-sectional differences of the above regime switching effect based on country-specific characters and find that the regime switching effect is associated with a nation’s country-specific characters such as openness, economic size and so forth.

Description: Sustainability, Vol. 10, Pages 2729: Assessment of Postural Load during Melon Cultivation in Mediterranean Greenhouses Sustainability doi: 10.3390/su10082729 Authors: Marta Gómez-Galán José Pérez-Alonso Ángel-Jesús Callejón-Ferre Julián Sánchez-Hermosilla-López Health and safety at work directly influence the development of sustainable agriculture. In the agricultural sector, many farm workers suffer musculoskeletal disorders caused by forced posture. The objective of this research is to assess working postures during melon cultivation in Almería-type greenhouses. The Ovako Working Posture Assessment System (OWAS) has been used with pictures of the tasks. The variables studied by multiple correspondence analysis were as follows: Subtask, Posture code, Back, Arms, Legs, Load, Risk, and Risk combination. The OWAS analysis showed that 47.57% of the postures were assessed as risk category 2, 14.32% as risk category 3, 0.47% as risk category 4, and the rest as risk category 1. Corrective measures should be implemented immediately, as soon as possible, or in the near future, depending on the risks detected.

Description: Sustainability, Vol. 10, Pages 2785: How Does Project Supervisor Maintain Sustainability of Project Members? A Study from Leadership Perspective Sustainability doi: 10.3390/su10082785 Authors: Han-Sheng Lei Chuan-Fu Lai Chih-Chang Chen Project members’ innovative behavior is crucial to their sustainability and successful implementation of the project. This research develops a conceptual model to explore the effect of project supervisor leadership skills on member’s innovative behavior. The model is examined by a sample of 437 project members in Taiwan. The results show that project supervisors’ emotional healing positively influences members’ innovative behavior through affect-based trust in their supervisor and supervisor conceptual skill has an inverted-U impact on members’ innovative behavior through cognition-based trust in their supervisor. This paper further discusses implications of these conclusions for additional research on the association between leadership skills and innovative behavior.

Description: Sustainability, Vol. 10, Pages 2772: Estimates of Daily PM2.5 Exposure in Beijing Using Spatio-Temporal Kriging Model Sustainability doi: 10.3390/su10082772 Authors: Jinhuang Lin An Zhang Wenhui Chen Mingshui Lin Excessive exposure to ambient (outdoor) air pollution may greatly increase the incidences of respiratory and cardiovascular diseases. Accurate reports of the spatial-temporal distribution characteristics of daily PM2.5 exposure can effectively prevent and reduce the harm caused to humans. Based on the daily average concentration data of PM2.5 in Beijing in May 2014 and the spatio-temporal kriging (STK) theory, we selected the optimal STK fitting model and compared the spatial-temporal prediction accuracy of PM2.5 using the STK method and ordinary kriging (OK) method. We also reveal the spatial-temporal distribution characteristics of the daily PM2.5 exposure in Beijing. The results show the following: (1) The fitting error of the Bilonick model (BM) model which is the smallest (0.00648), and the fitting effect of the prediction model of STK is the best for daily PM2.5 exposure. (2) The cross-examination results show that the STK model (RMSE = 8.90) has significantly lower fitting errors than the OK model (RMSE = 10.70), so its simulation prediction accuracy is higher. (3) According to the interpolation of the STK model, the daily exposure of PM2.5 in Beijing in May 2014 has good continuity in both time and space. The overall air quality is good, and overall the spatial distribution is low in the north and high in the south, with the highest concentration in the southwestern region. (4) There is a certain degree of spatial heterogeneity in the cumulative duration at the good, moderate, and polluted grades of China National Standard. The areas with the longest cumulative duration at the good, moderate and polluted grades are in the north, southeast, and southwest of the study area, respectively.

Description: Sustainability, Vol. 10, Pages 2767: On Decision Makers’ Perceptions of What an Ecological Computer Model is, What It Does, and Its Impact on Limiting Model Acceptance Sustainability doi: 10.3390/su10082767 Authors: Fabio Boschetti Michael Hughes Cheryl Jones Hector Lozano-Montes Environmental decision makers are required to understand complex ecological processes and ecological computer models are designed to facilitate this understanding. A set of interviews reveals three main perceptions affecting senior environmental decision makers’ trust in ecological computer models as decision facilitation tools: an ecological computer model is perceived as (i) a ‘black box’, (ii) processing poorly documented, sparse and out-of-date input data, and (iii) whose sensitivity to model parameters enables manipulation to produce desired outcomes justifying pre-conceived decisions. This leads to lack of trust towards both ecological computer models and model-users, including other scientists and decision makers. Model acceptance appears to depend on the amount, currency and geographical origin of input data. This is at odds with modellers’ communication style, which typically places more emphasis on highlighting the ecological computer model’s features and performance, rather than on describing the input data. Developing ‘big data’ capabilities could deliver the large, real-time, local data that may enhance acceptance. However, the size and complexity of ‘big data’ requires automated pre-processing, using modelling and algorithms that are even more inscrutable than current ecological computer models. Future trust in ecological computer models will likely depend on how this dilemma is resolved, which is likely to require improved communication between modellers and decision makers.

Description: Sustainability, Vol. 10, Pages 2777: Sustainability Assurance in Socially-Sensitive Sectors: A Worldwide Analysis of the Financial Services Industry Sustainability doi: 10.3390/su10082777 Authors: Elies Seguí-Mas Fernando Polo-Garrido Helena María Bollas-Araya Sustainability reporting and assurance have considerably increased in the last decades. Among different sectors, ‘sensitive sectors’ attracted the attention of many academics. However, most of research works were focused only on ‘environmentally-sensitive sectors’. Therefore, after the loss of trust caused by the lack of transparency due to the crisis, ‘socially-sensitive sectors’ as financial services sector needs to strengthen users’ confidence in the credibility of their reported activities. The aim of this paper is to assess assurance practices worldwide in one of the main ‘socially-sensitive sectors’: the financial services sector. We study what factors are associated with adoption of assurance and choice of assurance provider, and whether assurance statements differ across providers. Our results reveal that, compared to the global context, companies operating in the financial services sector are more likely to adopt assurance and to choose accountants as assurance providers. Our findings show that adoption of assurance depends on company size. We also found that companies using the financial services sector supplement are more prone to adopt assurance. Our results also evidence that choice of assurance provider depends on the country and listing status Finally, our research shows a great variability in assurance statements across providers.

Description: Sustainability, Vol. 10, Pages 2762: Technological Entrepreneurship: How does Environmental Turbulence Impact upon Collaboration Risk? Sustainability doi: 10.3390/su10082762 Authors: Iwona Staniec The aim of this paper is to identify the impact of environmental turbulence on the risk of cooperation in technological entrepreneurship. Multidimensional factors such as the risk of cooperation, environmental turbulence, and the reaction to operationalized changes were selected during the literature review, and were subjected to empirical verification on a 304 element sample of SMEs, which are implementing technology entrepreneurship. The study used a questionnaire interview technique conducted directly in the company, and the research tool was a specially prepared questionnaire. Because of the multidimensional character of the studied variables, structural modelling was chosen. In addition, the influence of selected mediators and moderators on the relationship between the turbulence of the environment and the risk of cooperation in technological entrepreneurship was examined. The article has been divided into five main sections. The first section constitutes the introduction to the deliberations. A detailed review of the literature, taking into account the principles of operationalization of each of the presented variables, is discussed in the second section. The methodology used is then presented. In the next section of the paper, the results of the research are presented and then a broad discussion of these results is undertaken. The last section is a summary of the conducted research and its limitations. Knowledge about the antecedents of cooperation risk allows for the minimization of the presence of adverse phenomena, while knowledge of the directions of their impact greatly enriches the experience in the management of this type of relationship. The presented research may contribute to the construction of a rational model of the cooperation risk management process, in particular, in the case of adopting resources existing within the organization.

Description: Sustainability, Vol. 10, Pages 2802: Bi-Objective Scheduling Optimization for Discrete Time/Cost Trade-Off in Projects Sustainability doi: 10.3390/su10082802 Authors: Hongbo Li Zhe Xu Wenchao Wei In sustainable project management, time and cost are two critical factors affecting the success of a project. Time/cost trade-offs in projects accelerate the execution of some activities by increasing the amount of non-renewable resources committed to them and therefore shorten the project duration. The discrete time/cost trade-off problem (DTCTP) has been extensively studied during the past 20 years. However, due to its complexity, the DTCTP—especially the DTCTP curve problem (DTCTP-C)—has only been solved for relatively small instances. To the best of our knowledge, there is no computational performance analysis for solving the DTCTP-C on large project instances with up to 500 activities. This paper aims to fill this gap. We present two bi-objective heuristic algorithms for the DTCTP-C where both project duration and cost are minimized. The objective is to obtain a good appropriate efficient set for the large-scale instances. The first algorithm is based on the non-dominated sorting genetic algorithm II (NSGA-II) and uses a specially designed critical path-based crossover operator. The second algorithm is a steepest descent heuristic which generates efficient solutions by iteratively solving the DTCTP with different deadlines. Computational experiments are conducted to validate the proposed algorithms on a large set of randomly generated problem instances.

Description: Sustainability, Vol. 10, Pages 2800: A Framework for Spatiotemporal Analysis of Regional Economic Agglomeration Patterns Sustainability doi: 10.3390/su10082800 Authors: Rui Jin Jianya Gong Min Deng Yiliang Wan Xuexi Yang Understanding regional economic agglomeration patterns is critical for sustainable economic development, urban planning and proper utilization of regional resources. Taking Guangdong Province of China as the study area, this paper introduces a comprehensive research framework for analyzing regional economic agglomeration patterns and understanding their spatiotemporal characteristics. First, convergence and autocorrelation methods are applied to understand the economic spatial patterns. Then, the intercity spatial interaction model (ISIM) is proposed to measure the strength of interplay among cities, and social network analysis (SNA) based on the ISIM is utilized, which is designed to reveal the network characteristics of economic agglomerations. Finally, we perform a spatial panel data analysis to comprehensively interpret the influences of regional economic agglomerations. The results indicate that from 2001 to 2016, the economy in Guangdong showed a double-core/peripheral pattern of convergence, with strengthened intercity interactions. The strength and external spillover effects of Guangzhou and Shenzhen enhanced, while Foshan and Dongguan had relatively strong absorptive abilities. Moreover, expanding regional communication and cooperation is key to enhancing vigorous economic agglomerations and regional network ties in Guangdong by spatial panel data analysis. Our results show that this is a suitable method of reflecting regional economic agglomeration process and its spatiotemporal pattern.

Description: Sustainability, Vol. 10, Pages 2798: Bringing the Community Back: A Case Study of the Post-Earthquake Heritage Restoration in Kathmandu Valley Sustainability doi: 10.3390/su10082798 Authors: Stelios Lekakis Shobhit Shakya Vasilis Kostakis Heritage preservation is a resource-intensive activity nested among other processes in the public administration, related to identity building and touristic product enhancement. Strategies and schemata associated with heritage preservation sprang in the western world after WWII and they have been adapted, in the form of ‘heritage management’, in various contexts with questionable effectiveness regarding sustainability. Our paper discusses the case of the post-earthquake cultural, social and political landscape of the World Heritage Site of Kathmandu valley in Nepal. By reviewing the bibliography and drawing upon various case studies of post-earthquake heritage restoration, we focus on the traditional ways of managing human and cultural resources in the area as related to the modern national heritage management mechanism. We also examine how traditional practices, re-interpreted into a modern context, can point towards inclusive and sustainable forms of collaboration based on the commons. We shed light on the elements of an emerging management system that could protect the vulnerable monuments through community participation, adapted to the challenging realities of the Nepalese heritage and its stakeholders.

Description: Sustainability, Vol. 10, Pages 2792: The Causal Nexus between Oil Prices, Interest Rates, and Unemployment in Norway Using Wavelet Methods Sustainability doi: 10.3390/su10082792 Authors: Hyunjoo Kim Karlsson Yushu Li Ghazi Shukur This paper applies wavelet multi-resolution analysis (MRA), combined with two types of causality tests, to investigate causal relationships between three variables: real oil price, real interest rate, and unemployment in Norway. Impulse response functions were also utilised to examine effects of innovation in one variable on the other variables. We found that causal relations between the variables tend to be stronger as the wavelet time scale increases; specifically, there were no causal relationships between the variables at the lowest time scales of one to three months. A causal relationship between unemployment rate and interest rate was observed during the period of two quarters to two years, during which time a feedback mechanism was also detected between unemployment and interest rate. Causal relationships between oil price and both interest rate and unemployment were observed at the longest time scale of eight quarters. In conjunction with Granger causality analysis, impulse response functions showed that unemployment rates in Norway respond negatively to oil price shocks around two years after the shocks occur. As an oil exporting country, increases (or decreases) in oil prices reduce (or increase) unemployment in Norway under a time horizon of about two years; previous studies focused on oil importing economies have generally found the inverse to be true. Unlike most studies in this field, we decomposed the implicit aggregation for all time scales by applying MRA with a focus on the Norwegian economy. Thus, one main contribution of this paper is that we unveil and systematically distinguish the nature of the time-scale dependent relationship between real oil price, real interest rate, and unemployment using wavelet decomposition.

Description: Sustainability, Vol. 10, Pages 2795: Tasty or Sustainable? The Effect of Product Sensory Experience on a Sustainable New Food Product: An Application of Discrete Choice Experiments on Chianina Tinned Beef Sustainability doi: 10.3390/su10082795 Authors: Biancamaria Torquati Tiziano Tempesta Daniel Vecchiato Sonia Venanzi This study aims to contribute to the existing literature by verifying whether the degree of liking of a new food product influences people’s preferences and willingness to pay from a discrete choice experiment when dealing with sustainable food products. To this purpose, we considered the case study of the introduction into the Italian market of a new food product: tinned Chianina meat. Among the attributes considered for this new product, two in particular were related to sustainability: organic breeding and the preservation of a traditional rural landscape. Half of the respondents underwent a sensory test before taking part in the hypothetical market (discrete choice experiment), while the remaining were administered the tests in reverse order. Tasting the product before the discrete choice experiment did not produce different willingness to pay (WTP) parameters as estimated by a taste factor interaction. However, separating the respondents into those who liked or disliked the product in the tasting condition revealed differences in willingness to pay results. The preferences are different for more than 50% of the attributes considered, and the magnitude of this difference is quite relevant. The WTP for one well known and certified sustainability related attribute—organic breeding—was not affected by the liking, while, for the other—the preservation of a traditional rural landscape—the effect of liking decreases the WTP. As a consequence, we suggest that tasting and liking studies should be routinely coupled with discrete choice studies when analyzing the introduction of new food products, especially when considering sustainable attributes in the experimental design. In the case of organic products where the expectations about taste are higher, neglecting to consider their sensory perception, along with the other discrete choice experiment attributes, could seriously undermine their long lasting success on the market.

Description: Sustainability, Vol. 10, Pages 2797: The Cause and Evolution of Urban Street Vitality under the Time Dimension: Nine Cases of Streets in Nanjing City, China Sustainability doi: 10.3390/su10082797 Authors: Xiaodong Xu Xinhan Xu Peng Guan Yu Ren Wei Wang Ning Xu Street vitality is associated with a comfortable human-based public environment and urban sustainability. In most current studies, street vitality is assessed considering single or multi factors; however, the impact of time dimension is ignored. This study selects nine different year-built streets in old, main, and new urban areas, in Nanjing, China, proposes a framework to assess street vitality considering the different time dimensions and selects the following factors: street form, including building density, continuity, and height-width; street business type, including store density, function density, and permeation rate; and street accessibility, including location, the number of entrances/exits, transportation, and walkability. After calculating the values of the subfactors, a ranking method was applied to assign the ranking of impact of all factors for a comprehensive analysis. The results showed that Pipa Street, Wufu Street in a main urban area, and Hongmiao Street had the highest street vitality and the highest rankings of almost all the factors. Street vitality in different periods demonstrated that street vitality in new urban areas is lower compared with old and main urban areas.

Description: Sustainability, Vol. 10, Pages 2799: A Definition and Theoretical Review of the Circular Economy, Value Creation, and Sustainable Business Models: Where Are We Now and Where Should Research Move in the Future? Sustainability doi: 10.3390/su10082799 Authors: Tom Lahti Joakim Wincent Vinit Parida This paper contains a theory review of value creation and the implementation of next-generation sustainable business models to profit in the circular economy. While previous research has pointed to the influence of society and regulatory policy on companies’ ability to address larger sustainability concerns and to change their ways of working, the field suffers from little theoretical guidance outlining how undertake circular business mode transformation in practice. By reviewing the field’s main theories, we illustrate significant implications for how future research can study profitability and competitiveness in the circular economy. This paper introduces the central components of circular business models and discusses links to contingency theory, transaction cost theory, resource-based theory, theory on networks and industrial economics, and agency theory. Understanding the circular economy and the ways companies can compete in the circular economy based on these theories is important for establishing important new research directions for scholars of sustainable business and circular business models.

Description: Sustainability, Vol. 10, Pages 1975: Sustainable Legitimacy: Chinese Government Inspections and Public Approval of Village Leadership Sustainability doi: 10.3390/su10061975 Authors: Jinrui Xi Inspections to villages are an important mechanism for the Chinese government to gain and retain its ruling legitimacy. However, whether inspections have been effectively utilized for that designated purpose of sustainable governance remains less clear. We know very little about how the Chinese government employs inspections to boost its public approval. This study sets out to examine that effect, contending that inspections to Chinese villages significantly boost the public approval of village leaderships by promoting the governing efficacy of village leaders. The consistent practice of inspections results in a sustained level of public support for the Chinese government. This causal relationship between inspections and public approval holds, first, by improving village social welfare and economic development, and second, by securing for village leaders essential political and financial support from higher authorities to better represent villagers’ interests and mediate conflicts among villagers. Using data of 961 randomly selected villages across China, the empirical analysis shows that Chinese government inspections significantly boost villagers’ approval regarding their village leaders.

Description: Sustainability, Vol. 10, Pages 1873: Urban Foraging in Berlin: People, Plants and Practices within the Metropolitan Green Infrastructure Sustainability doi: 10.3390/su10061873 Authors: Jonah L. Landor-Yamagata Ingo Kowarik Leonie K. Fischer Gathering wild plants in cities (urban foraging) is likely an important, but understudied human-nature interaction globally. As large European cities are critically understudied in this regard, we performed in-depth ethnography-based interviews in Berlin, Germany, to shed light on the cultural background of foragers, their motivations and which plants and fungi are gathered for which purposes. Results demonstrate multiple uses of 125 taxa, mostly frequently-occurring species but also some Red List species, from a range of formal and informal greenspace types. Both native and non-native species were gathered, with significant differences in use patterns. Use for food was most common, followed by medicinal uses, and personal enjoyment was a frequent motivation, indicating that urban foraging combines provisioning and cultural ecosystem services. Familial and childhood foraging exposure were common, pointing to influences of early-in-life exposure on later-in-life activities and transgenerational aspects of the practice. Results further suggest legacy effects from the post-war and communist eras on foraging knowledge. Although non-commercial foraging is allowed in Berlin, over-harvesting was not evident. Interviews indicate that stewardship of urban biodiversity is common among foragers. Results thus suggest considering urban foraging as a promising vehicle for linking humans with nature when developing a biodiverse urban green infrastructure.

Description: Sustainability, Vol. 10, Pages 1870: A Quantitative Method for Prediction of Environmental Aspects in Construction Sites of Residential Buildings Sustainability doi: 10.3390/su10061870 Authors: Luis Claudio A. Borja Sandro Fábio César Rita Dione A. Cunha Asher Kiperstok Despite the sectoral initiatives, the construction industry faces difficulties in incorporating effective environmental impact control systems in construction sites. Most of the instruments have been adopting a qualitative approach to environmental issues, with few cases of a quantitative approach. This article introduces a quantitative method for predicting environmental aspects and impacts during the construction of residential buildings, through the integration between environmental indicators and construction cost bases. The methodology was based on the analysis of the relationships among activities, aspects and environmental impacts considered in EU Eco-Management and Audit Scheme (EMAS) for the development of the method and its mathematical representation. A case study was carried out to evaluate the method using the bill of quantities (BOQ) from two residential construction sites to measure their environmental aspects. The results suggest the usefulness of the method in the decision-making process on the allocation of control systems and, in some cases, recommending the execution of off-site services to reduce the impacts on the site’s neighborhood. Additionally, the method proved to be easy to apply to evaluate construction sites, as well as flexible to incorporate other activities, adapting to the demand of builders and municipalities to reduce the environmental impacts of construction sites.

Description: Sustainability, Vol. 10, Pages 1875: Integrating Functions for a Sustainable Urban System: A Review of Multifunctional Land Use and Circular Urban Metabolism Sustainability doi: 10.3390/su10061875 Authors: Saskia van Broekhoven Anne Lorène Vernay Cities pose environmental challenges but also offer possibilities to close material and energy loops and connect multiple societal and ecologic services. This article reviews and brings together the literature on two important new research directions that address urban sustainability by integrating functions or material flows: Circular Urban Metabolism (CUM) and Multifunctional Land Use (MLU). We focus on challenges to MLU and CUM and strategies to facilitate their realization. The review shows that although MLU and CUM differ in what they integrate, they face partly similar integration challenges. In both fields, the collaboration between actors related to particular functions (water safety, recreation), high investment costs and uncertainties about costs and benefits, and legislation that hampers integration are identified as challenges. In both fields, strategies are proposed to facilitate the collaboration between actors. However, other challenges and strategies are specific. Whilst MLU scholars mostly highlight socio-economic aspects of realizing integration, CUM scholars focus more on technical aspects. We find limited cross-fertilization between both fields so far. To stimulate discussion and knowledge exchange, we introduce ‘integration of urban functions’ as a shared idea for a sustainable urban system. To find further solutions for integration challenges, we propose conceptualizing MLU or CUM initiatives as processes of change, which requires connecting across previously separate ‘worlds’ and changing previously established monofunctional ways of working.

Description: Sustainability, Vol. 10, Pages 1868: Associations between Public Transit Usage and Bikesharing Behaviors in The United States Sustainability doi: 10.3390/su10061868 Authors: Yuanyuan Zhang Yuming Zhang Public bikesharing systems have rapidly expanded across many cities in the United States (US). Previous studies in the literature found that, in general, bikesharing is associated with public transit ridership. However, the interdependencies between public transit usage and bikesharing behaviors have been mixed and have not been fully understood. Therefore, the objective of this research is to examine the associations between the frequency of public transit usage and the probability and frequency of bikesharing usage in the US using data from the 2017 National Household Travel Survey. The respondents were asked how many times they had used public transit and bikesharing in the last 30 days. Zero-inflated negative binomial regression models were conducted to assess the associations between the frequency of public transit usage and the probability and frequency of bikesharing usage. The results show that, in general, a one-unit increase in the frequency of public transit usage is significantly associated with a 4.0% increase in the probability of bikesharing usage and a 1.4% increase in the frequency of bikesharing usage. The significantly positive relationship between the frequency of public transit usage and the frequency of bikesharing usage is more pronounced among those living in areas with higher population density or with rail service. The empirical results demonstrate that public transit usage is significantly positively associated with bikesharing usage, and suggest policy implications that improving public transit usage tends to increase the usage of bikesharing. This study also provides significant empirical evidence for the formulation of interventions and policies targeting to promote integrated transportation systems that support multimodal transportation and mutually sustainable transport networks.

Description: Sustainability, Vol. 10, Pages 1867: Organic Carbon Concentrations in High- and Low-Productivity Areas of the Sulu Sea Sustainability doi: 10.3390/su10061867 Authors: Charissa M. Ferrera Gil S. Jacinto Chen-Tung Arthur Chen Hon-Kit Lui The sequestration of anthropogenic carbon dioxide in the form of organic carbon and its eventual deposition in the sediments is an important component of the marine carbon cycle. In the Sulu Sea, Philippines, organic carbon contents in the sediments have been relatively well studied, but the processes that describe the organic carbon distributions in the water column have not been elucidated. Dissolved and particulate organic carbon (DOC, POC) concentrations were measured at several stations in the Sulu Sea during the northeast monsoon of 2007/2008 to understand the dynamics of organic carbon in this unique internal sea. Analyses of primary productivity estimates, beam attenuation coefficient (at 660 nm) profiles, and correlation coefficients among DOC, POC and other parameters (e.g., apparent oxygen utilization) at different layers of the water column indicate that surface primary productivity, upwelling, bottom intensified flows across sills, and ventilation from shallow sills, which may contain semi-labile DOC that is estimated to largely contribute to microbial respiration in the bathypelagic layer, are the major processes that affect the DOC and POC distributions in the Sulu Sea. The variability of these processes should be taken into consideration when assessing the sustainability of internal and marginal seas as carbon sinks.

Description: Sustainability, Vol. 10, Pages 1866: Efficiency Assessment of Inbound Tourist Service Using Data Envelopment Analysis Sustainability doi: 10.3390/su10061866 Authors: Han-Shen Chen Bi-Kun Tsai Gwo-Bao Liou Chi-Ming Hsieh The successful and sustainable development of inbound tourism necessitates a long-term commitment, balancing between tourism supply and tourist demands. This study manipulated a performance appraisal of tourism service quality in Taiwan with Data Envelopment Analysis (DEA) by employing input and output constructs to assess service quality efficiency. The empirical results of the estimation of technical efficiency (TE) revealed that (1) the domestic tourism market is competitive, but still needs enhancements for tourism service; (2) Mainland Chinese tourists had the highest score among all foreign tourists, followed by Hong Kong and Macau tourists, tourists from other countries, Japanese tourists, and South Korean tourists; and (3) South Korean tourists had higher travel expenditure than others, but felt less satisfaction with travel services, which can be regarded as inefficient. Tourists from other countries had lower travel expenditure, but had higher satisfaction levels, which was considered efficient based on input and output index. The findings could contribute to bridging the gap between research and practice in assessing the efficiency of inbound tourist service. Tourism practitioners should be aware of tourists’ needs and interests, as these could be key fundamentals for improving tourists’ satisfaction with Taiwan’s service offerings.

Description: Sustainability, Vol. 10, Pages 1865: sEMG-Based Gesture Recognition with Convolution Neural Networks Sustainability doi: 10.3390/su10061865 Authors: Zhen Ding Chifu Yang Zhihong Tian Chunzhi Yi Yunsheng Fu Feng Jiang The traditional classification methods for limb motion recognition based on sEMG have been deeply researched and shown promising results. However, information loss during feature extraction reduces the recognition accuracy. To obtain higher accuracy, the deep learning method was introduced. In this paper, we propose a parallel multiple-scale convolution architecture. Compared with the state-of-art methods, the proposed architecture fully considers the characteristics of the sEMG signal. Larger sizes of kernel filter than commonly used in other CNN-based hand recognition methods are adopted. Meanwhile, the characteristics of the sEMG signal, that is, muscle independence, is considered when designing the architecture. All the classification methods were evaluated on the NinaPro database. The results show that the proposed architecture has the highest recognition accuracy. Furthermore, the results indicate that parallel multiple-scale convolution architecture with larger size of kernel filter and considering muscle independence can significantly increase the classification accuracy.

Description: Sustainability, Vol. 10, Pages 1863: Cycle Tourism as a Driver for the Sustainable Development of Little-Known or Remote Territories: The Experience of the Apennine Regions of Northern Italy Sustainability doi: 10.3390/su10061863 Authors: Patrizia Gazzola Enrica Pavione Daniele Grechi Paola Ossola One form of cycle tourism can be represented features tourism that focuses on the relation between biking and the discovery of a territory. Geared toward forms of holiday that allow for the low consumption of natural resources and a connection with the landscape, cycle tourism represents a concrete expression of sustainable tourism. As an emerging phenomenon in Italy, cycle tourism requires further understanding in order to identify methods of development and applicable business models. The aim of this paper is to explore the characteristics of cycle tourism’s development in northern Italy in order to identify the links that exist between sustainability and the group of cycle tourists who prefer to spend their holidays discovering little-known or remote territories. For this study, we selected three different destinations in sensitive mountain areas that converge on the common goal to use cycling to rejuvenate the tourism sector. It has been found that the development of cycle tourism in areas not characterized by mass tourism, such as those considered here, is economically, socially, and environmentally beneficial. The business models through which cycle tourism usually develops include a bottom up approach or a top down approach, involving the cooperation of several local destination stakeholders.

Description: Sustainability, Vol. 10, Pages 1862: Vulnerability Assessment of Rural Households to Urmia Lake Drying (the Case of Shabestar Region) Sustainability doi: 10.3390/su10061862 Authors: Rasoul Maleki Mehdi Nooripoor Hossein Azadi Philippe Lebailly One of the most important environmental problems in Iran is the destruction and drying of Urmia Lake (UL). UL is one of the main causes of suitable weather for agricultural boom and tourist attraction and it should be considered that the villagers exposed to UL drying have a strong dependence on vulnerable resources such as water, air, soil and plants for their livelihoods and have low adaptive capacity with this crisis for reasons such as poverty, lack of awareness and lack of infrastructure. This study was designed to evaluate the vulnerability of rural households to UL drying in the Shabestar region. The vulnerability was calculated based on Intergovernmental Panel on Climate Change (IPCC) definition and using vulnerability index (VI). Research population included rural households of Shabestar region (N = 19,249) and about 347 households were selected as the research sample using multistage cluster sampling technique. Results showed that the average score of respondents was 0.455 (moderate) in exposure, 0.359 (moderate to low) in sensitivity, 0.404 (moderate to low) in adaptive capacity and finally, the vulnerability index (VI) was 0.470 (range of 0 to 1). 12.8% of households had low, 70.5% had medium and 16.7% had high vulnerability towards UL drying.

Description: Sustainability, Vol. 10, Pages 1861: Ecological Risk Assessment of the Southern Fujian Golden Triangle in China Based on Regional Transportation Development Sustainability doi: 10.3390/su10061861 Authors: Xinyi Yang Lina Tang Yuqiu Jia Jiantao Liu Regional transportation development (RTD) is an important stressor of urban agglomeration ecosystems. Groundwater recharge potential may be adversely affected when natural soil is replaced by impervious materials. To systematically identify the urban agglomeration ecological risk (UAER) of RTD in the southern Fujian Golden Triangle, water regulation was used as an assessment endpoint, and RTD was considered the stressor. We used the Soil Conservation Service Curve Number method (SCS-CN) to analyze the internal relationship between the assessment endpoint and the stressor factors. Then, a multi-level risk characterization method was used to show the evolutionary process of risk, and to provide a scientific basis for the management of UAER. Based on the current RTD plan, the UAER assessment shows that there is a 0.90 probability of that the risk distribution results will occur by 2030. The intensity of stress from arterial roads on the urban agglomeration ecosystem is greater than that of the railway system. By considering the development of the railway system as a factor in the stress of RTD, this study of UAER assessment differs from past studies of urban ecological risk assessment, since the latter considers only highways. We also propose a systematic method of risk assessment simulation-prediction.

Description: Sustainability, Vol. 10, Pages 1859: Culture as a Prerequisite for Sustainable Development. An Investigation into the Process of Cultural Content Digitisation in Romania Sustainability doi: 10.3390/su10061859 Authors: Mina Fanea-Ivanovici In an age of rapid technological changes, new ways of cultural production–consumption and dissemination–access to cultural content are creating great opportunities for promoting cultural heritage at home and abroad as a prerequisite for sustainable development. The aims of this paper are to scrutinize the main opportunities of the process of cultural content digitisation with a focus on Romania and to highlight the main fields in which the country is still lagging behind. The article discusses technical internet-related endowment and use of internet by households in urban and rural areas, the existing digital cultural content, the importance of open access, e-accessibility, digital archives, e-museums, e-libraries, etc., as well as the main national and European strategies and agendas that Romania has based its cultural digitisation and heritage preservation priorities on. The paper is an empirical inquiry into the progress achieved, the positioning among the other European countries and the perspectives of cultural digitisation for Romania. Such matters are important determinants of smart, sustainable and inclusive growth, as long as access to public services and cultural content is a major objective of Europe 2020 Strategy.

Description: Sustainability, Vol. 10, Pages 1860: Analysis of the Land Use and Cover Changes in the Metropolitan Area of Tepic-Xalisco (1973–2015) through Landsat Images Sustainability doi: 10.3390/su10061860 Authors: Armando Avalos Jiménez Fernando Flores Vilchez Oyolsi Nájera González Susana M. L. Marceleño Flores Land use and cover changes (LUCC) have been identified as one of the main causes of biodiversity loss and deforestation in the world. Fundamentally, the urban land use has replaced agricultural and forest cover causing loss of environmental services. Monitoring and quantifying LUCC are essential to achieve a proper land management. The objective of this study was to analyze the LUCC in the metropolitan area of Tepic-Xalisco during the period 1973–2015. To find the best fit and obtain the different land use classes, supervised classification techniques were applied using Maximum Likelihood Classification (MLC), Support Vector Machines (SVMs) and Artificial Neural Networks (ANNs). The results were validated with control points (ground truth) through cross tabulation. The best results were obtained from the SVMs method with kappa indices above 85%. The transition analysis infers that urban land has grown significantly during 42 years, increasing 62 km2 and replacing agricultural areas at a rate of 1.48 km2/year. Forest loss of 5.78 km2 annually was also identified. The results show the different land uses distribution and the dynamics developed in the past. This information may be used to simulate future LUCC and modeling different scenarios.

Description: Sustainability, Vol. 10, Pages 1869: The Determinant Factors of Travelers’ Choices for Pro-Environment Behavioral Intention-Integration Theory of Planned Behavior, Unified Theory of Acceptance, and Use of Technology 2 and Sustainability Values Sustainability doi: 10.3390/su10061869 Authors: Li-Min Chuang Pi-Ching Chen Yen-Yu Chen From a previous literature review, there are rare studies that focus on integrating Sustainability Values (SVs), the Theory of Planned Behavior (TPB), and Unified Theory of Acceptance and Use of Technology (UTAUT2) to predict potential travelers’ behavioral intentions. In light of this, the research is designed to propose a comprehensive understanding of potential travelers’ choices for sustainable hospitality businesses by integrating SV, TPB, and UTAUT2 into a theoretical framework, by moderating the effect of age. Prior studies have mentioned TPB identified the role of attitude, perceived behavior control, and moral obligation in generating intention. However, the use of TPB and the extended UTAUT model to explain pro-environmental behavior is lacking. Data was collected from 34 northern, 2 central, and 6 southern Taiwanese consolidated headquarter travel agencies. Email questionnaires were distributed to 630 individuals in 42 travel agencies. The proposed model will be also examining, with an AMOS procedure of structural equation modeling (SEM), the maximum likelihood method of estimation. The results indicated that (1) SVs are positively and significantly impacted by pro-environmental behavioral intention; (2) SVs are positively and significantly impacted by attitude, social influence, perceived behavioral control, and habit respectively; (3) attitude, perceived behavioral control, and habit is positively mediated by the effect between SVs and pro-environmental behavioral intention, respectively; (4) the social demographic variable of age is positively moderated the effect between SVs and social influence.

Description: Sustainability, Vol. 10, Pages 1985: Applying Blockchain Technology: Evidence from Norwegian Companies Sustainability doi: 10.3390/su10061985 Authors: Anne H. Gausdal Karen V. Czachorowski Marina Z. Solesvik The aim of this study is to develop a theoretical framework for blockchain, operations in particular. Furthermore, we aim to identify the main drivers and barriers of digital innovation and explore the general possibilities of blockchain applications within the maritime industry. A case study approach is applied: the Norwegian offshore industry. Primary data is collected through interviews, while secondary data is collected from industrial and company reports, the Internet, and national and international media reports. We have discovered that cost reduction intentions, the high level of regulation in the maritime industry, and the large amount of data that maritime companies should process, along with the intention to work more effectively, are the main drivers of digital innovation. On the other hand, the high cost of implementation, the bad quality of Internet connections offshore, the old age of decision-makers, the technology-oriented culture, the lack of investment initiatives, the low level of blockchain diffusion through the supply chain, and risk aversion are the main barriers. The results of the qualitative study show that some of the barriers and motives of digital innovation and the introduction to blockchain technology were pointed out by earlier studies. However, we have identified several unique drivers and barriers specific to the industry. Finally, the blockchain process framework is developed.

Description: Sustainability, Vol. 10, Pages 1997: Land Ownership, Rent-Seeking, and Rural Gentrification: Reconstructing Villages for Sustainable Urbanization in China Sustainability doi: 10.3390/su10061997 Authors: Jinkun Yang Eddie C. M. Hui Wei Lang Xun Li Gentrification is a widespread urban phenomenon across the post-industrial world. However, rural gentrification has been explored insufficiently in the context of China’s unprecedented urbanization. By reviewing the redevelopment processes in Zengcuoan village, Xiamen City, China, this study empirically reveals that the socio-spatial transformation of this village has been mainly led by artists and villagers based on institutional arrangements of land ownership. Rural gentrification, which involves refurbishing houses and public spaces, has played a key role in social life and the engagement between indigenous villagers and artists. As active rent-seekers, indigenous villagers contribute to gentrification in a combined effect with China’s rural land property rights. Contrary to Western findings, villagers in China act as landlords who benefit from rural gentrification, which in turn causes grassroots artists or young people to move out because of the increasing rent or property prices. This paper attempted to enrich the extant understanding of rural Chinese gentrification and broaden the analytics of gentrification studies of the institutional arrangements from a land-ownership perspective. Contributing to the literature on rural gentrification, this study highlights the excessive commercialization of rent-seeking as the trigger of gentrification.

Description: Sustainability, Vol. 10, Pages 1990: Institutional Perspectives of Climate-Smart Agriculture: A Systematic Literature Review Sustainability doi: 10.3390/su10061990 Authors: Edmond Totin Alcade C. Segnon Marc Schut Hippolyte Affognon Robert B. Zougmoré Todd Rosenstock Philip K. Thornton Climate-smart agriculture (CSA) is increasingly seen as a promising approach to feed the growing world population under climate change. The review explored how institutional perspectives are reflected in the CSA literature. In total, 137 publications were analyzed using institutional analysis framework, of which 55.5% make specific reference to institutional dimensions. While the CSA concept encompasses three pillars (productivity, adaptation, and mitigation), the literature has hardly addressed them in an integrated way. The development status of study sites also seems to influence which pillars are promoted. Mitigation was predominantly addressed in high-income countries, while productivity and adaptation were priorities for middle and low-income countries. Interest in institutional aspects has been gradual in the CSA literature. It has largely focused on knowledge infrastructure, market structure, and hard institutional aspects. There has been less attention to understand whether investments in physical infrastructure and actors’ interaction, or how historical, political, and social context may influence the uptake of CSA options. Rethinking the approach to promoting CSA technologies by integrating technology packages and institutional enabling factors can provide potential opportunities for effective scaling of CSA options.

Description: Sustainability, Vol. 10, Pages 2020: Assessing the Climate Change Impacts of Biogenic Carbon in Buildings: A Critical Review of Two Main Dynamic Approaches Sustainability doi: 10.3390/su10062020 Authors: Charles Breton Pierre Blanchet Ben Amor Robert Beauregard Wen-Shao Chang Wood is increasingly perceived as a renewable, sustainable building material. The carbon it contains, biogenic carbon, comes from biological processes; it is characterized by a rapid turnover in the global carbon cycle. Increasing the use of harvested wood products (HWP) from sustainable forest management could provide highly needed mitigation efforts and carbon removals. However, the combined climate change benefits of sequestering biogenic carbon, storing it in harvested wood products and substituting more emission-intensive materials are hard to quantify. Although different methodological choices and assumptions can lead to opposite conclusions, there is no consensus on the assessment of biogenic carbon in life cycle assessment (LCA). Since LCA is increasingly relied upon for decision and policy making, incorrect biogenic carbon assessment could lead to inefficient or counterproductive strategies, as well as missed opportunities. This article presents a critical review of biogenic carbon impact assessment methods, it compares two main approaches to include time considerations in LCA, and suggests one that seems better suited to assess the impacts of biogenic carbon in buildings.

Description: Sustainability, Vol. 10, Pages 2021: Linkages Between acequia Farming and Rangeland Grazing in Traditional Agropastoral Communities of the Southwestern USA Sustainability doi: 10.3390/su10062021 Authors: Stephanie C. López Andrés F. Cibils Ursula R. Smedly Steven J. Guldan Alexander G. Fernald Carlos G. Ochoa Kenneth G. Boykin Lilian Cibils Many agropastoral systems worldwide are supported by important linkages between crop production and rangeland grazing. We explored the connections between smallholder farming and public rangeland grazing in northern New Mexico, USA. We retrieved historical data of livestock inventories, drought, and hay production which we analyzed using either ordinary least squares models, generalized autoregressive conditional heteroscedasticity models (GARCH), or exponential GARCH models. We also conducted a survey of farmers and ranchers (n = 74) of traditional communities in our study area using a mixed methods design. County hay production was the only predictor that explained year-to-year variation in allotment livestock numbers. Allotments that increased livestock numbers tended to have larger base properties (mostly irrigated cropland). Most survey respondents (95%) raised livestock and slightly more than half agreed that livestock provided better financial security than crops. Availability of summer grazing lands and ability to grow or purchase hay to feed livestock during winter were the factors cited least (6% of responses) and most (42%), respectively, as limiting farmers’ ability to increase their herd size. Livestock-raising apparently continues to be critical to the acequia agropastoral economy. Ability to acquire winter feed (hay) appears to regulate the demand for summer grazing on public forested rangelands.

Description: Sustainability, Vol. 10, Pages 1976: Tourism and Sustainability: A Bibliometric and Visualization Analysis Sustainability doi: 10.3390/su10061976 Authors: Fernando J. Garrigos-Simon Yeamduan Narangajavana-Kaosiri Ismael Lengua-Lengua Sustainability is a growing research topic in tourism due to the importance of environmental and social issues, and the maintenance of patrimony and other facilities to conserve the potential of tourism destinations. Specifically, sustainability in tourism is crucial in order to guarantee a consistent development of destinations, measured by growth in income and employment. This relevance has been translated into an explosive growth in the sustainability literature regarding tourism, income, and employment. However, there is a lack of bibliometric and visualization research on tourism sustainability (TS), and specifically on its relationship with income and employment. This paper aims to present a bibliometric overview of TS research, and specifically TS related to income and employment. The current work analyzed 2279 references collected from the Web of Science (WoS) Core Collection database and used the visualization of similarities (VOS)viewer program to graphically map the material. The study used co-occurrence of keywords, co-citation, bibliographic coupling, and co-authorship analyses. The results identify the development status and the leading trends in terms of impact, main journals, papers, topics, authors, institutions, and countries. The analysis and graphical presentations are relevant, as they can help researchers and practitioners better understand the state of the art of TS.

Description: Sustainability, Vol. 10, Pages 1974: An Empirical Study on Sustainable Innovation Academic Entrepreneurship Process Model Sustainability doi: 10.3390/su10061974 Authors: Xiao-Duo Qian Jing Xia Wei Liu Sang-Bing Tsai As academic entrepreneurs, university faculty members and researchers with rich knowledge resources play an important role in the technology commercialization process, and in the creation and development of university spinoff enterprises. In this paper, we used a case study method to construct a sustainable innovative academic entrepreneurship process model from the perspective of entrepreneurial behavior. Then, we used this model to provide a deeper understanding of the activities and roles of academic entrepreneurs. This paper also expounded the process of value creation that is a result of sustainable innovative academic entrepreneurship, and compared and analyzed three types of university technology commercialization models. Our results showed that in the sustainable innovative academic entrepreneurship process model, the motivation of academic entrepreneurs leads them to play multiple roles as academic researchers, enterprise founders, and enterprise managers. In creating enterprises as the founders, and establishing and developing their enterprises, academic entrepreneurs realize the commercial value of the technology, while also incrementing their personal value. The sustainable innovative academic entrepreneurship process model provides a new path for effective transfer of technological innovations from academic research to the commercial market, creates social as well as economic value, and promotes regional economic development.

Description: Sustainability, Vol. 10, Pages 1972: Laboratory Experiments of Tradable Development Rights: A Synthesis of Different Treatments Sustainability doi: 10.3390/su10061972 Authors: Till Proeger Lukas Meub Kilian Bizer Tradable development rights (TDR) are considered by scholars and regulators in various countries as a means of reducing land consumption efficiently. Similar to the development of CO2-certificate trading schemes, the methodology of experimental economics can be used to derive empirical evidence on the core parameters and problems of TDR schemes, thus extending theoretical modelling and evidence from case studies. Building on a common laboratory experimental framework, we discuss results from five distinct experiments that consider mechanisms of allocation, resilience against external shocks, political business cycles, communication and collusion, and risk. These results provide initial empirical directions for the further study and introduction of TDR schemes for managing and reducing environmental issues related to land consumption for building projects.

Description: Sustainability, Vol. 10, Pages 1970: A Questionnaire Case Study of Chinese Opinions on the Haze Pollution and Economic Growth Sustainability doi: 10.3390/su10061970 Authors: Frederick Qiu Ethan Wang Matthew Fan Hong Liao Litao Wang Zuyi Huang Haze pollution in China has reshaped daily life for the Chinese and led to serious health issues. At the same time, the Chinese have enjoyed the rapid economic growth that has contributed to this pollution. While questionnaire-based studies have been conducted within certain regions of China to learn the public’s opinions of haze pollution, little work has been done to understand how Chinese citizens value haze treatment in relation to their nation’s economic growth at a nationwide scale. To fill this knowledge gap, this project conducted a nationwide investigation of Chinese opinions on the benefits of economic growth versus the disadvantages of haze pollution, as well as their responses to efforts by the Chinese government to combat haze and to the influence of haze on Chinese daily life and on personal health. The study also sought suggestions for combatting haze. In particular, an anonymous questionnaire consisting of 29 questions was given in the summer and fall of 2017 to 1233 people of different genders, ages, child statuses, educational backgrounds, occupations, living areas (rural, suburban, and urban), and living regions. The statistical Chi squared test was then used to identify the demographic group of respondents supporting the economic slowdown policy or requesting more efforts from the Chinese government to combat haze pollution. A multivariate statistical approach—principal component analysis—was further applied to visualize respondents’ feedback on the impact of haze on their daily life and personal health, as well as the change of environment and economic conditions in the last 10 years. The results show that more than 50% of respondents, especially those with children, those between the ages of 31 to 50, and those living in high-pollution regions, supported the economic slowdown policy. Totally 40.63% of the entire group of respondents believed the government’s efforts to control haze were small or very small. Only 27.84% of respondents held the opposite opinions. In total, 72.91% of respondents believed the environment in China became worse or much worse in the past 10 years; however, most responded positively to the idea of resolving the haze issue within 15 or more years. Haze has caused health issues in and around half of the respondents and has significantly reshaped their outdoor activities.

Description: Sustainability, Vol. 10, Pages 2006: Analysis, Evaluation and Optimization Strategy of China Thermal Power Enterprises’ Business Performance Considering Environmental Costs under the Background of Carbon Trading Sustainability doi: 10.3390/su10062006 Authors: Xiaohua Song Xiao Jiang Xubei Zhang Jinpeng Liu With the development of China’s energy structure adjustment and energy conservation and emission reduction, China’s carbon trading market has been fully launched. As an important participant in the carbon trading market, thermal power enterprises that play a major role in China’s power supply structure may bear huge environmental cost pressures, including carbon transaction costs. Under such a circumstance, thermal power enterprises urgently need to ensure operating performance through environmental cost management. This article takes the thermal performance of Chinese thermal power companies under the background of carbon trading as the study object, designs a measurement method for the environmental costs of thermal power companies, and analyzes the influence mechanism of the environmental cost based on the principle of system dynamics. Relying on the correlation analysis between environmental costs and business performance of thermal power companies, the company’s business performance is evaluated by data envelopment analysis (DEA) efficiency. After reaching the study conclusion, the article proposes an optimization strategy for thermal enterprises to manage and control their environmental cost and business performance. This paper closely integrates the actual background of carbon trading, including carbon transaction costs into environmental costs, and conducts an econometric analysis. It constructs a composite measurement of environmental costs that accounts for carbon transaction costs and conducts performance evaluations of power generation companies based on factors such as environmental costs, which all has a certain degree of innovation.

Description: Sustainability, Vol. 10, Pages 2005: The Development of Sustainable Entrepreneurship Research Field Sustainability doi: 10.3390/su10062005 Authors: Paul Sarango-Lalangui Jane Lucia S. Santos Esther Hormiga Sustainable entrepreneurship has received substantial recognition from academics and practitioners in the last decade, with a noticeable and rapidly increases of publications on the topic. Through bibliometric techniques and tools, this study allows mapping the main academic literature on sustainable entrepreneurship and analyzes the most substantial contributions to the advances of research in this field. The chronological analysis of literature from the Web of Science-Social Sciences Citation Index (WoS-SSCI) database—until January 2018—provides new insights not previously reviewed, such as the journals, authors and articles more influential so far. As a result, 282 articles were retrieved, which were published in 140 journals and written by 663 authors affiliated to 413 institutions, from 50 countries. The analysis allowed identifying publication evolution over time, and provides clues about the opportunities for future research.

Description: Sustainability, Vol. 10, Pages 1967: Daily Emotional Labor, Negative Affect State, and Emotional Exhaustion: Cross-Level Moderators of Affective Commitment Sustainability doi: 10.3390/su10061967 Authors: Hyewon Kong Joo-Eon Jeon Employees’ emotional-labor strategies, experienced affects, and emotional exhaustion in the workplace may vary over time within individuals, even within the same day. However, previous studies on these relationships have not highlighted their dynamic properties of these relationships. In addition, although the effects of surface and deep acting on emotional exhaustion have been investigated in emotional-labor research, empirical studies on these relationships still report mixed results. Thus, we suggest that moderators may affect the relationship between emotional labor and emotional exhaustion. Also, this study examines the relationship between emotional labor and emotional exhaustion within individuals by repeated measurements, and verifies the mediating effect of a negative affect state. Finally, our study confirms the moderating effects that affective commitment has on the relationship between emotional labor and emotional exhaustion. Data was collected from tellers who had a high degree of interaction with clients at banks based in South Korea. A total of 56 tellers participated in the survey and responded for five working days. A total of 616 data entries were collected from the 56 respondents. We used a hierarchical linear model (HLM) to examine our hypothesis. The results showed that surface-acting emotional labor increases emotional exhaustion; furthermore, the relationship between surface acting emotional labor and emotional exhaustion is mediated by a negative affect state within individuals. In addition, this study verified that affective commitment buffers the negative effects that surface acting emotional labor has on emotional exhaustion. These results suggest that emotional labor is a dynamic process within individuals, and that emotional exhaustion caused by emotional labor differs among individuals, and is dependent upon factors such as the individual’s level of affective commitment.

McAloone The business benefits attained from ecodesign programs in manufacturing companies have been regularly documented by several studies from both the academic and corporate spheres. However, there are still significant challenges for adopting ecodesign, especially regarding the evaluation of these potential business benefits prior to the actual ecodesign implementation. To address such gap, this study proposes an exploratory and theory-driven framework based on logic models to support the development of business cases for ecodesign implementation. The objective is to offer an outlook into how ecodesign implementation can potentially affect key corporate performance outcomes. This paper is based on a three-stage research methodology with six steps. Two full systematic literature reviews were performed, along with two thematic analyses and a grounded theory approach with the aim of developing the business case framework, which was then evaluated by seven industry experts. This research contributes to the literature of ecodesign especially by laying out an ecodesign-instantiated logic model, which is readily available to be adapted and customized for further test and use in practice. Discussions on the usefulness and applicability of the framework and directions for future research are presented.

Description: Sustainability, Vol. 10, Pages 2003: Green Initiatives Adoption and Environmental Performance of Public Listed Companies in Malaysia Sustainability doi: 10.3390/su10062003 Authors: Nor Azah Abdul Aziz Tze San Ong Soon Yau Foong Rosmila Senik Hassan Attan Environmental issues bring about thoughtful questions on the roles of business organisations in society. Irrespective of whether they are contributing to a better environment or worsening it, organisations have to acknowledge environmental or green issues through impact research and measurement. This article aims to examine the extent of green initiatives adoption and its impact on environmental performance of public listed companies (PLCs) in Malaysia. A questionnaire survey was conducted on PLCs and data from 120 samples were analysed using a statistical tool partial least square-structural equation modelling (PLS-SEM). Interviews were also conducted with a few selected companies to obtain in-depth information on green practices and to support the survey findings. The findings reveal that the extent of green initiatives adoption and environmental performance is at moderate level. Green initiatives adoption positively affects the environmental performance of Malaysian PLCs. The present study contributes to the literature of environmental management in the context of green and sustainable development. It also provides some important contributions for management practices by providing empirical evidence to managers that green initiatives should be extensively adopted to enhance environmental performances.

Description: Sustainability, Vol. 10, Pages 2014: Two-Stage Coordinate Optimal Scheduling of Seawater Pumped Storage in Active Distribution Networks Sustainability doi: 10.3390/su10062014 Authors: Ning Liang Changhong Deng Yahong Chen Weiwei Yao Dinglin Li Man Chen Peng Peng The percentage of penetration in renewable energy generation (REG) in distribution networks has dramatically increased. Variable speed seawater pumped storage, which has a large power controllable range and flexible modes of operation, is an important tool to be applied in distribution networks to realize peak shaving and valley filling, and to mitigate the negative effects of REG. This paper presents a two-stage coordinated optimal scheduling model for the day-ahead and real-time operation of active distribution networks containing seawater pumped storage, REG, and flexible loads. In the model, seawater pumped storage and flexible loads are dispatched in the first day-ahead stage based on short-term forecast information of REG and load demands to minimize total operational costs. Then in the second real-time stage, the operation schedule of seawater pumped storage is adjusted to mitigate the negative effects of forecast errors of REG on the operation of active distribution networks. Network nodes power quality is improved and power loss is reduced. Applying the model, disadvantages of low accuracy short-term forecast are minimized whereas advantages of high accuracy ultra-short term forecast are fully taken. This model is tested using a modified Institute of Electrical and Electronics Engineers 33-bus system. Numerical results demonstrate the effectiveness of the proposed approach.

Description: Sustainability, Vol. 10, Pages 2015: The Principal–Agent Leasing Model of “Company + n Farmers” under Two Division Modes Sustainability doi: 10.3390/su10062015 Authors: Jianjun Yu Xiaohuan Zheng Yongwu Zhou Qiongzhi Zhang The principal–agent leasing model consisting of one risk-neutral company and n risk-averse farmers is proposed by taking into consideration the characteristics of contract-farming and the fulfilment issues existing in the production process of agricultural products. We also discuss the optimal incentive coefficients and rents for n farmers under the two strategies of decentralization and concentration. The analysis suggests that the two division modes have no influence on the determination of the optimal effort level and the incentive coefficient of each party, and under the n farmers, the incentive coefficient given by the company to a single farmer household is not affected by the conditions of other farmer households. In terms of rent, land rent in the decentralized mode is strictly higher than land rent under the centralized mode. In the two modes of division, the total income of the company and the farmers is equal. Taking into account the randomness of the production process of agricultural products, the company will prefer to choose the centralized mode, and the farmers will tend to choose the decentralized mode in cooperation.

Description: Sustainability, Vol. 10, Pages 2044: Optimum Size Selection of CHP Retrofitting in Existing UK Hotel Building Sustainability doi: 10.3390/su10062044 Authors: Abdulazeez Rotimi Ali Bahadori-Jahromi Anastasia Mylona Paulina Godfrey Darren Cook Several studies have highlighted Combine Heat and Power (CHP) systems to be one of the proven and reliable technologies that can improve the efficiency of heat and electricity generation. The extensive adoption of this type of technology is crucial in reducing building emissions globally and in the U.K. This work uses a dynamic simulation software to evaluate the effect of CHP on the energy performance of an existing U.K. hotel and subsequently an approach to aid in the selection of optimum CHP size. The outcome of the study indicated that CHP systems in hotel buildings can provide considerable economic and environmental benefits with either maximally-sized CHP founded on the building’s base heat demand or with reduced CHP size of more than 50% smaller than the estimated maximum size. The optimum size design can be obtained through evaluation of the relationship between the main performance parameters and their variation with CHP sizes.

Description: Sustainability, Vol. 10, Pages 2039: Comprehensive Value Discovery of Land Consolidation Projects: An Empirical Analysis of Shanghai, China Sustainability doi: 10.3390/su10062039 Authors: Yishao Shi Xiangyang Cao Dongmei Fu Yuncai Wang The purpose of land consolidation is to promote moderately sized agricultural operations, intensive land use, concentrated population living and agglomerated industrial development. Previous research has primarily been macro- or mesoscale studies based on land ledger data, and analyzed only the effect of land consolidation on landscape ecological changes, only the resource and economic effects, or social effects or environmental effects of land consolidation. Aimed at addressing these shortcomings, an empirical analysis on the micro-scale based on land use patch data rather than land ledger data was conducted. Then, comprehensive research on land consolidation projects by integrating landscape pattern analysis with production, living, and ecological benefit assessments was performed. Furthermore, the relationship between land consolidation projects and the “Three Concentrations” policy was considered. The results show that: (1) land consolidation has directly or indirectly improved landscape ecological patterns of the project area; and (2) land consolidation has clearly improved the balanced distribution of cultivated land and the concentrated distribution of construction land in the project area. These changes not only improve the living conditions of farmers but also meet the construction requirements of the “Three Concentrations” in the Shanghai metropolitan suburbs.

Description: Sustainability, Vol. 10, Pages 2037: The Role of Environment in Sustainable Entrepreneurial Orientation. The Case of Family Firms Sustainability doi: 10.3390/su10062037 Authors: Felipe Hernández-Perlines Manuel Alejandro Ibarra Cisneros This study analyzes the role of the environment in the sustainable entrepreneurial orientation on the international performance of family firms. The results have been analyzed with Partial Least Squares regression. The three most important contributions of this work are: (1) The definition of sustainable business orientation as a third-order composite that integrates entrepreneurial orientation and corporate social responsibility is adequate as it presents appropriate values of reliability and validity; (2) entrepreneurial orientation is the main component of sustainable entrepreneurial orientation, with having corporate social responsibility a plus for entrepreneurial orientation; and (3) sustainable entrepreneurial orientation manages to explain 58.6% of the variability in the international performance of family firms and, finally, the environment has a positive moderating role, increasing up to 73.5%.

Description: Sustainability, Vol. 10, Pages 2034: Hybrid Energy System with Optimized Storage for Improvement of Sustainability in a Small Town Sustainability doi: 10.3390/su10062034 Authors: Fengchang Jiang Haiyan Xie Oliver Ellen With the rise of renewable energy comes significant challenges and benefits. The current studies on the incorporation of renewable-energy policies and energy-storage technologies attempt to address the optimization of hybrid energy systems (HESs). However, there is a gap between the currents needs of HES in small towns for energy independence and the understanding of integrated optimization approaches for employing the technology. The purpose of this research is to determine the technical, systematic and financial requirements needed to allow a city or community to become independent of the utilization of traditional energy and develop a reliable program for a clean and environment-friendly energy supply. This paper presents the sensitivity analysis and Bayesian prediction (SABP) method for the optimized design of a hybrid photo-voltaic wind energy system. This method uses the actual data to analyze and compare the main, optimized and desired scenarios of HES designs. The results show that optimized design can minimize the cost of the energy generated while reliably matching local electricity demand. The SABP system helps to eliminate the dependence on traditional energy resources, reduce transition costs by purchasing electricity, and decrease the financial burden of a small city.

Description: Sustainability, Vol. 10, Pages 2030: Designing Learning for Sustainable Development: Digital Practices as Boundary Crossers and Predictors of Sustainable Lifestyles Sustainability doi: 10.3390/su10062030 Authors: Andreja Istenic Starcic Maja Terlevic Lin Lin Maja Lebenicnik Sustainable development (SD) is a multidimensional issue. However, research findings report a divide between students’ awareness and behavior. It is identified that study programs are designed more for awareness outcomes, and not so much for behavioral outcomes. For higher-order learning outcomes manifested in a sustainable development behavior, the authors argue for a model based on an understanding of learning as boundary crossing. Based on this model, learning for sustainable development occurs in relating social practices, lifestyles, academic practices, professional practices, and students’ digital practices. To inform teachers’ approaches to teaching as an important driver of institutional change, we conducted a survey among students of urban and spatial planning in Slovenia. Examined factors included personal, academic, and digital predictors for sustainable development awareness, lifestyle, and behavioral intention. We hypothesized that a significant predictor for sustainable development behavior, which was measured as sustainable lifestyle and sustainable development behavioral intention, would be learning in social practices, and that learning in social practices would predict preferred teaching methods. The findings of hierarchical regression analysis indicated personal factors as the most important predictors of SD behavioral intention, and academic predictors as the most important factors for SD awareness. Digital practices were found to be the most important predictors of a sustainable lifestyle. Social practices of sustainable lifestyle, digital practices, and perceived teaching methods predicted students’ preferred teaching methods. We discuss the future directions of sustainable development education, considering digital social media practices as essential boundary crossers.

Description: Sustainability, Vol. 10, Pages 2031: Green City Concept and a Method to Measure Green City Performance over Time Applied to Fifty Cities Globally: Influence of GDP, Population Size and Energy Efficiency Sustainability doi: 10.3390/su10062031 Authors: Ogenis Brilhante Jannes Klaas There are many concepts and methods trying to accommodate the growth of cities without impairing sustainability. However, most are too complex, cannot measure green performance over time and fail to deliver actionable advice to decision-makers. The Green City Concept (GCC) is one of the latest of these concepts. This paper introduces a Green City Conceptual Framework (IHS-GCCF) and a harmonized method to measure Global Green City Performance over time (GGCPI). The IHS-GCCF highlights the importance of energy as a steward of resource efficiency and green performance. IHS-GCCF and GGCPI can be used to measure green performance, to explain possible factors influencing the calculated green performances over time, set targets and track achievements. They are adaptable to individual city needs. By applying the method to fifty cities worldwide through desk research, the paper shows that a green city is also sustainable and liveable. It also shows that GDP influences Green City Performances positively, population size influences it negatively and sanitation and air quality sectors influence green city performance the most. The paper addresses a range of gaps in the green city field. It consolidates prior research into one actionable conceptual framework and method.

Description: Sustainability, Vol. 10, Pages 2025: Determinants of Organic Cotton Apparel Purchase: A Comparison of Young Consumers in the U.S.A. and South Korea Sustainability doi: 10.3390/su10062025 Authors: Tae-Im Han The purpose of this research was to examine consumers from distinct cultural groups and identify similarities and differences in their green purchase behaviors. The sample consisted of consumers from the U.S.A. and South Korea and the theory of planned behavior was used as a theoretical framework to test the influence of diverse constructs on consumers’ purchase intentions toward organic cotton apparel. For both countries, perceived behavioral control (PBC) and descriptive norms were strong predictors of purchase intentions and injunctive norms strongly influenced attitude formation. However, the study also found different results between the two groups. For example, while attitude was the strongest predictor of purchase intentions in the U.S.A. group (strength of influence on intentions: attitude > descriptive norms > PBC > injunctive norms), it had an insignificant effect in the South Korea group. For the South Korea group descriptive norms and PBC had strongest effects on consumers purchase intentions (strength of influence on intentions: descriptive norms = PBC > injunctive norms > attitude). South Koreans were more affected by the social pressure: their purchase intentions were strongly influenced by both injunctive norms and descriptive norms in contrast to the findings from American consumers. Injunctive norms were an insignificant predictor of purchase intentions in the U.S.A. group. This result is consistent with previous research that suggest conformity is a crucial factor for people belonging to a collectivistic culture. Exposure of others’ purchasing behavior is particularly important in motivating consumers’ buying in collectivistic culture. Marketers of organic cotton apparel may consider using diverse formats of media to display consumers’ ethical buying behaviors or creating product design or packaging that can directly reveal the ethical features of the product to display greater exposure in the market.

Description: Sustainability, Vol. 10, Pages 2024: Antecedents for College Students’ Environmentally Responsible Behavior: Implications for Collective Impact and Sustainable Tourism Sustainability doi: 10.3390/su10062024 Authors: Yu Pan Jian-Guo Liu With the advent of mass tourism, tourism-related environmental problems are often reported in the news media. Tourists’ environmentally responsible behaviors (TERB) are critical for solving tourism environmental problems. This study argues that college students are a critical source of collective impact for tourism sustainability, and examines chained relationships that might determine college student TERB. Five hundred and twenty-five (525) college tourists were surveyed. Structural equation modeling was used to determine the relationships among the variables and the mediating effects. Results confirmed our proposed relationships of chained influences from tourism destination image (as key information) to tourist expectation (as cognition), to perceived quality and value (as experiences), to tourist satisfaction, loyalty, and complaints (as emotional reflection), and finally to TERB. Such results shed light on TERB education and construction, as well as on the collective impact for sustainable tourism.

Description: Sustainability, Vol. 10, Pages 2048: A Predictive Analytics Understanding of Cooperative Membership Heterogeneity and Sustainability Sustainability doi: 10.3390/su10062048 Authors: Matthew Elliott Lisa Elliott Evert Van der Sluis Recent advances in cooperative theory have focused on membership heterogeneity as being a significant challenge for cooperative sustainability. We use predictive analytics to forecast U.S. farmer cooperative sustainability at an aggregate level and include multiple dimensions of membership heterogeneity. We report the importance and shape of the effect of membership heterogeneity when predicting and forecasting cooperative sustainability in the near-term. We also report forecasts of cooperative sustainability given expected changes to membership heterogeneity. The data this study used are from the United States Department of Agriculture (USDA)-Economic Research Service (ERS) Agricultural Resource Management Survey (ARMS) joined with USDA-Rural Development cooperative financial data at the state level. Membership heterogeneity was found to be less relevant than other variables included in the model for predicting cooperative business volume and number of cooperatives headquartered per state, and an estimate of cooperative sustainability. Membership heterogeneity effects were mostly offsetting given expected changes to member heterogeneity, and/or were offset due to changes to other macro factors. Consequently, we conclude membership heterogeneity may affect the number of cooperatives and extent consistent with theoretical literature at a micro level; however, we also expect a similar level of sustainability of cooperatives at an aggregate level in the near-term despite changes to membership heterogeneity.

Description: Sustainability, Vol. 10, Pages 2047: Garden Pollinators and the Potential for Ecosystem Service Flow to Urban and Peri-Urban Agriculture Sustainability doi: 10.3390/su10062047 Authors: Gail Ann Langellotto Andony Melathopoulos Isabella Messer Aaron Anderson Nathan McClintock Lucas Costner Hedgerows, flowering strips, and natural areas that are adjacent to agricultural land have been shown to benefit crop production, via the provision of insect pollinators that pollinate crops. However, we do not yet know the extent to which bee habitat in the form of urban gardens might contribute to pollination services in surrounding crops. We explored whether gardens might provision pollinators to adjacent agricultural areas by sampling bees from gardens in the Portland, Oregon metropolitan area, and estimating typical foraging distances in the context of commercial- and residential-scale pollination-dependent crops up to 1000 m from garden study sites. We estimate that garden bees could forage outside of the garden in which they were collected, and that when pollination-dependent crops (commercial-scale or residential-scale) are nearby, 30–50% of the garden bee community could potentially provide pollination services to adjacent crops, if urban bees readily cross boundaries and forage among habitat types. Urban gardens might thus be well-positioned to provision neighboring farms and food gardens with pollination services, or could serve as a refuge for pollinators when forage is scarce or crop management practices are inhospitable. The actual capacity of gardens to serve as a refuge for pollinators from agricultural fields depends upon the extent to which bees forage across habitat types. However, relatively little is known about the degree to which bees move among habitat patches in heterogeneous landscapes. We thus propose a research agenda that can document the extent to which gardens contribute to pollinator health and pollination services at the interface of urban, peri-urban, and rural landscapes. In particular, more data is needed on how landscape context impedes or promotes garden bee movement between habitat types.

Description: Sustainability, Vol. 10, Pages 2046: Pre-Disaster Social Capital and Disaster Recovery in Wenchuan Earthquake-Stricken Rural Communities Sustainability doi: 10.3390/su10062046 Authors: Jianwen Wei Yang Han This study examined the impact of social capital on disaster recovery in the 2008 earthquake-stricken rural communities in Wenchuan, China. The results show that quake-affected households having more social capital recovered more easily and quickly from disasters. A larger network significantly increased the amount of government aid received for housing reconstruction. This indicates that network members assist the quake-affected households to apply for and obtain government aid. These findings imply that social capital, as a kind of non-institutionalized social force, facilitates earthquake-affected households’ recovery from disaster in rural China. Based on these results, this study suggests that policymakers should pay special attention to improving the social capital of existing local households to improve disaster recovery.

Description: Sustainability, Vol. 10, Pages 2045: Water Footprint in Supply Chain Management: An Introduction Sustainability doi: 10.3390/su10062045 Authors: Dimitrios Vlachos Eirini Aivazidou The aim of this Special Issue is to explore water-related risks and challenges, as well as water management opportunities, in the modern globalised production landscape from an end-to-end supply chain perspective. As environmentally sensitive consumers press for water-friendly products, freshwater resources’ preservation has emerged as a major challenge for leading corporations that are incorporating water management initiatives into their social responsibility agendas to foster the sustainability of their supply chain networks. With respect to the scientific community, although research on water footprint assessment is increasing rapidly, the lack of a systemic integration of the water footprint aspect into the whole spectrum of the supply chain operations is evident. In this context, this Special Issue focuses on the investigation of the impact of water stewardship policies on water use and scarcity minimisation, sustainability performance and supply chain configuration.

Description: Sustainability, Vol. 10, Pages 2052: Sustainability of the Urban Transport System under Changes in Weather and Road Conditions Affecting Vehicle Operation Sustainability doi: 10.3390/su10062052 Authors: Dmitriy Zakharov Elena Magaril Elena Cristina Rada The paper suggests a methodological approach for assessing the sustainability of the urban transport system. Parameters were selected for assessing the sustainability of the transport system and significant factors affecting sustainability were determined. Parameters of the sustainability of the system when changes in the weather and road conditions affect vehicle operation were estimated on the basis of the simulation modeling. An integral indicator of sustainability was introduced to evaluate the sustainability of the transport flow management subsystem and the methodological approach to its calculation was substantiated. The results from changing the parameters of the traffic flow were demonstrated in the case of a significant amount of precipitation and the constraints put on the movement of vehicles on the road infrastructure unit due to snow-removal operations and road traffic accidents. Also, the parameters of road traffic under the reconstruction of the main street of regulated traffic into a street of uninterrupted traffic were presented.

Description: Sustainability, Vol. 10, Pages 2061: Heterogeneous Preferences for Public Goods Provided by Agriculture in a Region of Intensive Agricultural Production: The Case of the Marchfeld Sustainability doi: 10.3390/su10062061 Authors: Andreas Niedermayr Lena Schaller Petr Mariel Pia Kieninger Jochen Kantelhardt The aim of this paper is to elicit the marginal willingness to pay (MWTP) for the improved provision of public goods (PGs) by agriculture in a region of intensive agricultural production, embodying many of the environmental problems related to agriculture within and outside the European Union (EU). Our analysis was based on a participatory approach, combining the involvement of local stakeholders and a discrete choice experiment (DCE) in the Marchfeld region in Austria. We estimated a random parameters logit model (RPL), including interactions with socio-demographic factors, to disentangle preference heterogeneity and find a positive MWTP of the local population for all three PGs analyzed: (i) groundwater quality; (ii) landscape quality; and (iii) soil functionality in connection with climate stability. Furthermore, MWTP varies considerably with respect to age, farmers/non-farmers and locals/incomers. Further research could combine the results of this demand-side valuation with those of a supply-side valuation, where the opportunity costs of different management options for farmers are estimated. Based on such a cost–benefit analysis and further participation of local stakeholders, new governance mechanisms for the smart and sustainable provision of PGs by agriculture could be developed for the Marchfeld region and for comparable European regions.

Description: Sustainability, Vol. 10, Pages 2085: Sustainability of University Technology Transfer: Mediating Effect of Inventor’s Technology Service Sustainability doi: 10.3390/su10062085 Authors: Fang Li Sheng Zhang Yuhuan Jin Based on the perspective of knowledge transfer and the technology acceptance model (TAM), this paper constructs a university technology transfer sustainable development model that considers the inventor’s technology service from the perspective of the long-term cooperation of enterprise, and analyzes the mediating effect of the inventor’s technology service on university technology transfer sustainability. By using 270 questionnaires as survey data, it is found that the availability of an inventor’s technology service has a significant positive impact on the attitude tendency and practice tendency of enterprise long-term technological cooperation; enterprise technology absorption capacity and trust between a university and an enterprise also have significant influence on an inventor’s technical service availability. Therefore, the inventor’s technology service acts as a mediator in the relationship between university technology transfer sustainability and influence factors. Universities ought to establish the technology transfer model, which focuses on the inventor’s tacit knowledge transfer service, and promotes the sustainable development of the university.

Description: Sustainability, Vol. 10, Pages 2083: How to Address the Sustainability Transition of Farming Systems? A Conceptual Framework to Organize Research Sustainability doi: 10.3390/su10062083 Authors: Guillaume Martin Sandrine Allain Jacques-Eric Bergez Delphine Burger-Leenhardt Julie Constantin Michel Duru Laurent Hazard Camille Lacombe Danièle Magda Marie-Angélina Magne Julie Ryschawy Vincent Thénard Hélène Tribouillois Magali Willaume Stakeholders from academic, political, and social spheres encourage the development of more sustainable forms of agriculture. Given its scale and scope, the sustainability transition is a challenge to the entire agricultural sector. The main question is, how to support the transition process? In this article, we explore how agricultural science can address the sustainability transition of farming systems to understand and support transition processes. We discuss the potential for articulating three research approaches: comprehensive analysis, co-design, and simulation modeling. Comprehensive analysis of the sustainability transition provides perspectives on the interplay between resources, resource management, and related performances of farming systems on the one hand and technical, economic, and sociocultural dimensions of change on the other. Co-design of the sustainability transition stimulates local-scale transition experiments in the real world and identification of alternatives for change. Simulation modeling explores future-oriented scenarios of management at multiple levels and assesses their impacts. We illustrate the articulation of research approaches with two examples of research applied to agricultural water management and autonomy in crop-livestock systems. The resulting conceptual framework is the first one developed to organize research to understand and support the sustainability transition of farming systems.

Description: Sustainability, Vol. 10, Pages 2074: The Creation of an Ecovillage: Handling Identities in a Norwegian Sustainable Valley Sustainability doi: 10.3390/su10062074 Authors: Hege Westskog Tanja Winther Marianne Aasen This paper presents a qualitative study of Hurdal Ecovillage in Norway. It explores how the actors involved have interacted over time and contributed to shaping the ecovillage. The study demonstrates that the ecovillage as a concept is continuously refined both internally on an individual level and in the village, and in mainstream society. At stake is the question of ecovillage identity and what this should entail. The interviewed ecovillagers report two main motives for deciding to move to the village. One is to become part of the ecovillage community, while the other is grounded in the ecovillage as a means to achieve sustainability rather than as a goal in itself. Hurdal Ecovillage has undergone two distinct development phases. First, the members jointly owned the land, built their own houses, and attempted to be self-sufficient. The ecovillage was largely isolated from the local community. In the second phase, professional actors took over responsibility for developing the village, offering ready-made houses to be owned by individual families. This shift resulted in the ecovillage appearing more like conventional settlements. Today’s ecovillagers express a wish to constitute an attractive, sustainable alternative to conventional living, but to do so they have to maintain a distance between themselves and the wider community.

Description: Sustainability, Vol. 10, Pages 2109: The Role of SMEs’ Green Business Models in the Transition to a Low-Carbon Economy: Differences in Their Design and Degree of Adoption Stemming from Business Size Sustainability doi: 10.3390/su10062109 Authors: María A. Quintás Ana I. Martínez-Senra Antonio Sartal The purpose of this paper is to analyze how SMEs define the components of their business models (value proposition, creation and capture) from the point of view of decarbonization. We analyze SMEs as a group, and study whether their size affects this process and, in both cases, we examine evolution over time. We use a database comprising 1161 observations of SMEs, 466 in 2014, and 695 in 2016. The results show that SMEs’ value propositions give an intermediate valuation to both legally required and voluntary reduction of environmental impact, irrespective of SME size and the year analyzed. Regarding value creation, SMEs adopt practically no environmental practices, and there are significant differences according to size, with more difficulties than advantages stemming from small size. The study also shows that such environmental practices are not effective in reducing carbon. This diagnosis indicates that SMEs need help from the administration if they are to play a key role in the process of transformation toward a low-carbon economy. Legislative actions involving harsher environmental protection measures might help shape value propositions that place greater importance on reducing environmental impact, whereas training actions on available environmental techniques, promotion of research on how to adapt such techniques to SMEs and the development of specific practices for SMEs might enhance environmental value creation and capture in their BMs.

Description: Sustainability, Vol. 10, Pages 2090: Critical Factors to Achieve Dockless Bike-Sharing Sustainability in China: A Stakeholder-Oriented Network Perspective Sustainability doi: 10.3390/su10062090 Authors: Jian-gang Shi Hongyun Si Guangdong Wu Yangyue Su Jing Lan In China, dockless bike-sharing programs (DBSPs) play a significant role in promoting the goals of sustainable urban travel and carbon emissions reduction. However, the sustainability of DBSPs is increasingly being challenged as various issues associated with different stakeholders emerge. While numerous studies have focused on the barriers to traditional bike-sharing programs, the sustainability performance of new-generation DBSPs is largely overlooked. It is accordingly imperative to understand the primary challenges that impede the sustainability of DBSPs and to consider what stimulative measures can be taken. In this study, we investigate the factors that are critical to DBSPs’ sustainability from a network perspective. Stakeholder-associated factors and their interrelations were identified via literature analysis and interviews, and the social network analysis (SNA) method was employed to recognize the critical factors and links in DBSPs. As a result, 10 critical factors and 10 major interactions were identified and further classified into six challenges. Sharing transport schemes, legislative perfection, public private partnership (PPP), and product lifecycle management (PLM) were proposed to govern these challenges. This paper contributes to the existing body of knowledge of bike-sharing programs via a network approach that integrates the key influencing factors with those factors’ associated stakeholders. Furthermore, these findings provide the government and operators with implications for mitigating the tough challenges and facilitating the sustainability of DBSPs.

Description: Sustainability, Vol. 10, Pages 2064: Contrasted Effects of Relative Humidity and Precipitation on Urban PM2.5 Pollution in High Elevation Urban Areas Sustainability doi: 10.3390/su10062064 Authors: Rasa Zalakeviciute Jesús López-Villada Yves Rybarczyk Levels of urban pollution can be influenced largely by meteorological conditions and the topography of the area. The impact of the relative humidity (RH) on the daily average PM2.5 concentrations was studied at several sites in a mid-size South American city at a high elevation over the period of nine years. In this work, we show that there is a positive correlation between daily average urban PM2.5 concentrations and the RH in traffic-busy central areas, and a negative correlation in the outskirts of the city in more industrial areas. While in the traffic sites strong events of precipitation (≥9 mm) played a major role in PM2.5 pollution removal, in the city outskirts, the PM2.5 concentrations decreased with increasing RH independently of rain accumulation. Increasing PM2.5 concentrations are to be expected in any highly motorized city where there is high RH and a lack of strong precipitation, especially in rapidly growing and developing countries with high motorization due to poor fuel quality. Finally, two models, based on a logistic regression algorithm, are proposed to describe the effect of rain and RH on PM2.5, when the source of pollution is traffic-based vs. industry-based.

Description: Sustainability, Vol. 10, Pages 2093: Coordinating the Dynamic Development of Energy and Industry in Composite Regions: An I-SDOP Analysis of the BTH Region Sustainability doi: 10.3390/su10062093 Authors: Xu Li Chinhao Chong Linwei Ma Pei Liu Xuesi Shen Zibo Jia Cheng Wang Zheng Li Weidou Ni In various regions of the world, there is an urgent need to address energy challenges by accelerating the transformation of energy and industrial systems. The problem is quite complex in rapidly developing composite regions, with the necessity to coordinate the dynamic development of energy and industry in several heterogeneous subregions. Through a typical case study on the Beijing–Tianjin–Hebei (BTH) region, this study attempts to form a referable methodology for the coordinated development of energy and industry for the sustainable development of rapidly developing composite regions. The concept of an Integrated strategy of Sustainable development objectives, Decision-making systems, Operation systems, and Physical systems (I-SDOP) is proposed to describe the multilayer dynamics of complex energy and industrial systems. A five-step I-SDOP analysis is conducted to determine an integrated strategy for the coordinated development of energy and industry in the BTH region, based on the analysis of its sustainable development objectives, decision-making systems, operation systems, and physical systems. The results indicate the importance of innovation sources and extensive communications to promote market reform and engineering projects that fulfill the strong political wills and strategic plans of China’s central government.

Description: Sustainability, Vol. 10, Pages 2141: Models for Analyzing the Dependencies between Indicators for a Circular Economy in the European Union Sustainability doi: 10.3390/su10072141 Authors: Adrian Dumitru Tantau Maria Alexandra Maassen Laurentiu Fratila The circular economy has become one of the main strategic issues on a global scale in the striving towards achieving sustainable economic systems. The traditional model of production, consumption and disposal is being transformed into a recycling and waste integration process from the beginning of the production cycle of a product until its full use by the consumers. While measuring the progress towards a circular economy can be a challenging factor, several indicators can be used to evaluate developments in this direction. That is why recycling in general, as well as recycling of municipal waste, have become a main strategic issue in the process towards implementation of circular economy principles. The main objective of the paper is to elaborate a panel regression model for determining the dependency between main indicators, that are indicating progress of the circular economy in Europe, such as the recycling rate of municipal waste, circular material use rate, R&D expenditure by all sectors, trade in recyclable raw materials and environmental tax revenues, resource productivity and domestic material consumption. Furthermore, the fixed and random effects regression models estimations are included and tested through the Durbin–Hausman–Wu statistic. The research in this study is based on the analysis of regressions in the circular economy fields in the European Union and intends to contribute to the research in the field, being an emerging scientific topic due to changing technological, economic and environmental factors.

Description: Sustainability, Vol. 10, Pages 2140: Building Energy Opportunity with a Supply Chain Based on the Local Fuel-Producing Capacity Sustainability doi: 10.3390/su10072140 Authors: Flavio Andreoli Bonazzi Sirio R.S. Cividino Ilaria Zambon Enrico Maria Mosconi Stefano Poponi Studying and modeling plants for producing electric power obtained from vegetal wood cellulose biomass can become an opportunity for building a supply chain based on the local fuel-producing capacity. Focusing on energy-producing technologies, such as pyrolysis or gasification, the present work assessed the amount of vegetal biomass that may be used as fuel, both in terms of actual availability and supply price, in the Province of Rieti (Italy). The aim is to draw up a supply plan that has an intrinsic relationship with the local area. The results confirmed a production of 24 MW of project thermal power and 4 MW of project electric power. The ensuing plant was then studied following current norms about renewable energy, environmental consistency, and atmospheric emissions. An economic analysis of the cost investment was also carried out, where the total return is approximately of 19%. The results exposed that plant costs are acceptable only if short-supply chain fuel is purchased. The costs of generating energy from agroforestry biomass are certainly higher; however, the plant represents a significant territorial opportunity, especially for the economic sectors of agriculture and forestry. The employment effect plays a central role in the concession process, which is relevant for the interaction among renewable energy production and agriculture. The environmental impact of a biomass plant from agroforestry residues can be measured exclusively on atmospheric emissions: the plant must be placed in industrial areas without any landscape or naturalistic value.
