Description: China’s climate change policy has rapidly evolved from one of neglect to necessity with sinologists drawing on a wide range of theories in trying to explain this shift. The rising influence of citizens' movements coupled with international pressure are often cited as significant drivers behind the government’s evolving climate change strategy. But can the influence of public pressure and international lobbying offer a complete explanation for the government’s dramatic policy changes? In this article, we advance theoretical pluralism where three contending schools of thought are made complementary to offer distinct explanations for understanding the mechanisms and rationale for Beijing’s elite-driven climate change policy. In brief, by bridging three separate theoretical streams including rational choice theory, authoritarian environmentalism and advocacy coalition framework, we show that the interests of elites in China’s upper political echelon are the driving force behind the country’s climate change policy.

Description: Canadian Census data for 1981–2006 is used to document substantial differences in the destination locations of immigrants and interprovincial migrants. These differences have increased over time as have differences in the characteristics of the two migrant groups. Differences in age, education, and marital status of the two migrant groups explain little of the observed differences. Visible minority status and language differences are somewhat more important; however, much of the difference in migrant group destinations cannot be explained by measured characteristics.

Description: Electricity markets in the Mediterranean basin countries are characterised by the substantial disparity in their degree of openness and competitiveness. . There is also a difference in the maturity of their economies and their rate of economic and population growth. For example, the South and East Mediterranean Countries (SEMCs), which currently account for a quarter of total GDP of the region, are expected to grow at twice the rate of the North Mediterranean Countries (NMCs) until the end of the next decade. Similarly, the population in SEMCs is growing at a faster rate than the in NMCs. This imbalance has profound implications for energy stability and trade in the region. Development of cross border interconnections could reduce the energy gap among sub-regional markets and pave the way towards a well-integrated energy market. Additionally, in order for renewable energy to play an important role in the energy markets of the region the national electricity systems of the Euro-Mediterranean countries needs to be highly interconnected. Against this background, this paper aims to analyse the development of cross-border interconnections in the Mediterranean basin in light of existing disparities in the state of market maturities, institutions, national energy goals and regional objectives. Our analysis aims to illustrate how current provisions that regulate and discipline cross border interconnections in the EU do not apply, in the short- to medium-term, to SEMCs. And how the current regulatory framework, while designed to favour competition in electricity supply, appears to be poorly adapted to addressing security of supply at a regional level.

Description: This paper provides a detailed analysis of the local community response to a newly installed rare earth (RE) refinery facility and the factors underlying its acceptance. House-to-house interviews, using structured questionnaire, were conducted in 2013 ( N  = 370). Results show that the community was divided into deciding whether they agreed with the presence of the facility, 41.36 % (for) and 41.62 % (against). The remaining fraction of the community was undecided, which made up 17.03 % of the total respondents. This paper identifies six significant predictors of risk acceptance: gender, education status, place of residence, Factor 1 (variables—perception of safety, concern on effects, and trust in the operators), Factor 2 (variables—social and individual benefits), and Factor 3 (variables—no confidence in government). This study gives insights on how the public respond to potential hazardous facilities and highlights the need for policy makers to consider public sentiment which can interfere with further expansion of the RE industry.

Description: Ghana’s electricity generation capacity is currently insufficient to meet demand, making power outages and load shedding common. The resulting impact is potentially devastating for the country’s growth prospects. Traditionally, lack of an affordable and reliable fuel supply for power generation, coupled with ineffective institutions and an unfavourable investment climate, have resulted in Ghana’s electricity sector performing poorly. In light of the 2007 discovery of natural gas reserves in Ghanaian waters, this paper examines whether domestic gas could advance the performance of the electricity sector, and if so, how. The results of our analysis show that utilization of gas reserves in Ghana’s gas-to-power market is an economically superior strategy compared to an export-oriented utilization scheme. The lack of an effective regulatory framework for investment, skill shortages, and an inefficient electricity pricing structure continue to be the main constraining factors. Our analysis also considers possible approaches to modification of the electricity tariff in order to send the right signal to potential investors in generation capacity, without compromising the affordability of power supply.

Description: Farming in coastal Bangladesh includes rice/shrimp and rice/non-rice cropping systems. The former has been highly profitable but has exacerbated salinization of soil and water. We evaluate the relative profitability, riskiness, and sustainability of the two cropping systems, using data from two coastal villages in Khulna District. Shrimp cultivation was initially very rewarding. However, over 12–15 years, the cropping system experienced declining profitability, increased salinity, and adverse impacts on rice cropping and the local environment. From 2009, farmers adapted the system by changing the pond ( gher ) infrastructure, adopting delayed planting of a saline-tolerant rice cultivar, flushing out accumulated salt with freshwater during rice cropping, and allowing the soil to dry out after harvesting rice. The budgeting results show that with current management practices, the rice/shrimp system is economically more viable (higher returns to land and labour and less risky) than the rice/non-rice system. Soil analyses showed that while salinity was higher in the gher during the dry season, it was significantly reduced in the wet season and was very similar between the two systems (1–2 dS/m). Hence, as well as being more profitable and less risky, the rice/shrimp system may well be more sustainable than previously observed.

Description: This paper examines the wage and job satisfaction effects of over-education and overskilling among migrants graduating from EU-15 based universities in 2005. Female migrants with shorter durations of domicile were found to have a higher likelihood of overskilling. Newly arrived migrants incurred wage penalties which were exacerbated by additional penalties resulting from overskilling in the male labour market and overeducation in the female labour market. Established migrants were found to enjoy wage premia, with no evidence of disproportionate wage impacts arising as a consequence of mismatch. Female migrants were found to have a lower probability of being job satisfied.JEL Classification Keywords: 1J21, J31, J61, Overeducation, Overskilling, Mismatch, Migrants, Gender, Pay, Job satisfaction.

Description: The aim of this paper was to present the contribution of the sugar cane industry to reduce carbon dioxide emissions in the energy sector. Mauritius is taken as a case study. Sugar cane was introduced in Mauritius during the seventeenth century and production of sugar started around 60 years later. Since then, the cane industry has been one of the economic pillars of the country. Bagasse, a by-product of sugar cane, is used as fuel in cogeneration power plants to produce process heat and electricity. This process heat and the generated electricity are used by an annexed sugar mills for the production of sugar, while the remaining electricity is exported to the national grid. In fact, Mauritius is a pioneer in the field of bagasse-based cogeneration power plant; the first bagasse-based cogeneration power plant that was commissioned in the world was in Mauritius in 1957. The contribution of the cane industry in the electricity sector has been vital for the economic development of Mauritius and also in terms of mitigating carbon dioxide emissions by displacing fossil fuels in electricity generation, as bagasse is classified as a renewable source. Data obtained from Statistics Mauritius on electricity production for the past 45 years were analysed, and carbon dioxide emissions were calculated based on international norms. It is estimated that savings on heavy fuel oil importation were by 1.5 million tons of oil—representing a value of 2.9 billion dollars—thus avoiding 4.5 million tons of carbon dioxide emissions. This figure can be further increased if molasses, a by-product of sugar cane juice, is used to produce bio-ethanol to be used as fuel in vehicles.

Description: This study presents information on the use of medicinal animals in a semiarid area of northeast Brazil, a region where animals have recognized importance in local popular medicine. The information on the use of animals for medicinal purposes was obtained through semi-structured questionnaires, complemented by free interviews and informal conversations. The results obtained showed that the residents of the area studied utilize a considerable richness of animal species ( n  = 42) for medicinal purposes, as occurs in other areas of Brazil’s semiarid region, demonstrating that zootherapy represents an alternative form of health care that is important to the inhabitants of the region. There is a need for new investigations on medicinal fauna, aimed at promoting the sustainable use of eventual medicinal species and preserving popular knowledge associated with the use of animal species.

Description: Switzerland changed its migration policy in the 1990s from a “non-qualified only” policy to one of almost free movement of labor. To analyze the impact of this policy change on the schooling outcomes of children of first-generation migrants, the paper compares the PISA results of first-generation pupils in 2000 with the scores of children tested in 2009, whose parents immigrated after the policy changed. We find that around 75% of the 40-point increase in the PISA score of first-generation immigrant students was due to changes in the individual background characteristics of their parents and to improved school composition.Jel codes: I21, I24, J15.

Description: This issue of the Oxford Energy Forum is dedicated to gas pricing. A mild 2013/14 winter in Europe and parts of Asia and a slowing of demand growth for LNG saw European hub prices and LNG spot prices begin to fall through the summer of 2014. The collapse of the oil price in late 2014 resulted in a lagged reduction in long-term contract prices (LNG and pipeline gas) to levels below $10/MMBtu in Europe and Asia. These events followed a period from 2011 to 2013 in which regional gas reference prices in the USA, Europe, and Asia appeared to be held within stable ‘corridors’ at levels which incentivized the progression of a long list of new LNG projects in North America, East Africa, Australia, and Russia. Many of these will likely be ‘on hold’ pending indications of a more supportive future price environment, but some 150 bcm/year of new LNG supply from the USA and Australia will have achieved start-up by 2020; this will add further pressure on prices and stimulate inter-regional arbitrage.

Description: Costa Rica is internationally recognized for its abundant biodiversity and being a leader in the promotion of education strategies for biodiversity conservation. We interviewed staff from 16 institutions developing key environmental communication, education, and participation projects for biodiversity conservation in the country. Through content analysis, hierarchical cluster analysis and Chi-square tests, we examined the characteristics of the projects carried out by these institutions and developed a typology of four categories derived from six variables: primary audience, content, project purpose, location, scale, and facility. Then, we designed a conceptual model describing the integration of conservation and economic development in the educational projects. We found two key approaches related to this integration: vision of nature protection which aims to inform audiences of ecological concepts and focuses on schoolchildren and vision of sustainability which engages adult audiences and is management-oriented. Education for community - based environmental management may serve as a good example of educational projects which integrate conservation and economic development, implementing a vision of sustainability.

Description: This paper investigates the impact of Fairtrade and organic certification on household income of smallholder coffee farmers in the Jinotega Municipality of Nicaragua. Using a sample of 233 coffee farming households and employing endogenous switching regression model and propensity score matching method, the results found that Fairtrade and organic certification standards have different effects on the certified farmers; while Fairtrade farmers had experienced yield gains, organic farmers had the price advantage. However, the overall impact of these certification standards on the total household income is found to be statistically not significant. While some of the Fairtrade-certified cooperatives have used the social premium in creating community-level infrastructure, there is a need for more investment. The major constraint the organic-certified farmers face is lack of availability of adequate organic inputs such as manures and organic herbicides.

Description: This study employs an ex-ante analytical approach to explore the financial viability of cocoa agroforestry systems in Ghana using cross-sectional data on smallholder cocoa farmers in the Western Region of Ghana. The empirical results generally show that cocoa agroforestry systems are profitable, but the medium shade tends to be more profitable. The no-shade cocoa agroforestry has the highest yield compared with other cocoa agroforestry systems. Sensitivity analysis revealed that increasing the market price by 12.2 % tends to increase the profitability of cocoa agroforestry systems. Also increasing fertilizer price does not lead to any significant change in the profitability. The study recommends the medium-shade cocoa agroforestry system as the most profitable agroforestry system for optimizing ecological and economic outcomes of smallholder cocoa farmers in sub-Saharan Africa.

Description: The recent development of infrastructure all around the world has resulted in an increasing trend of online examination in universities. The paper is an approach in theory and practical aimed at analyzing the feasibility of sustainable examination in four universities and its environmental impact reducing the paper use terming it as green examination. The paper studied the integration of sustainability through the use of computers and technology in the examination of the universities viz. King Khalid University (KKU), Saudi Arabia, Integral University (IU), India, Aligarh Muslim University (AMU), India, and The Hague University (HU), The Netherlands. The study has analyzed the trend of paper requirement, paper utilized and paper wasted in all the four universities. The environmental impact resulting from reduced paper use has been also analyzed. The feasibility of e-examination, its implementation and the implications has been undertaken in the study. The study concludes that the e-examination can almost make the examinations paperless and feasible in the four universities.

Description: Malaysia has made a pledge to reduce voluntarily her carbon dioxide-equivalent (CO 2 -e) gas emission’s intensity of gross domestic product by up to 40 % based on 2005 levels by 2020. The country is considering implementing economic instruments, among others, to assist the achievement of emission reduction targets while contributing towards the nation’s energy security and sustainable development goals. This paper develops a computable general equilibrium model with explicit energy-emission linkages to appraise the economy-wide and welfare impacts of carbon and energy tax policies to reduce CO 2 emissions in Malaysia. Results indicate that the negative macroeconomic impacts of carbon and energy taxes are small relative to the quantum of emission reduction. A Hicksian welfare criterion is utilized to determine the impact of revenue natural shifts in carbon and energy taxes. Revenue neutrality assumptions show that carbon taxation is the best choice when it can provide a double dividend if the generated revenue is used for the purpose of consumption subsidy on household purchases. The notion of the double dividend is confirmed when the change in the consumption structure will result in a welfare improvement, while CO 2 emission is decreased effectively. The study also found that carbon tax policy results in greater emission reductions relative to energy taxes, while the use of renewable energy will increase more substantially.

Description: Earthworms are so closely incorporated into the soil structure that they are not calculated easily from the soil. Due to this property, their extraction from soil is tedious and time-consuming. Different methods have been used for their extraction from the soil, and efficiency of each method is affected by physical properties, viz., temperature and moisture of the soil. This study explored the advantage and disadvantage of different sampling methods for the extraction of earthworms such as hand sorting, octet method, formalin method, mustard extraction method, allyl isothiocyanate (AITC), and onion extraction method. Extraction efficiency of formalin is 20–60 times more as compared to hand sorting, but hand sorting gives satisfactory results for earthworms of more than 0.2 g live weight, and cocoons can also be recovered by this method. Octet method is effective in extracting anecic species and could easily be applied to site where chemical extraction is not a viable option. Extraction by mustard and AITC is simple, low cost, and more efficient for the extraction of deep-burrowing anecic species. The onion extraction solution is low cost and nontoxic which can be used as alternative to formalin. Like mustard, the onion solution is also inexpensive and not harmful to the earthworms and environment.

Description: Data from the International Social Survey Programme 2000 and 2010 environment modules were analyzed to explore the relationships between attitudes, behavior, and sociodemographic variables to citizens’ preferences to aspects of environmental discourse in the Philippines. Overall, significantly more people agree to multilateralism, equity, and the link between the environment and economic progress in 2010 as compared to 2000. A series of multinomial logistic regressions were conducted to determine significant predictors to peoples’ disposition to variables related to three overarching environmental discourses. After controlling for other covariates, the study found that the more the Filipinos adhere to statements toward science and nature that are negatively connoted: the more likely they are to agree to international multilateral commitments and ascribe to equity for poorer countries in environmental efforts; and less likely to disagree to the aspects of multilateralism, equity, and the link between the environment and economic progress. Furthermore, the results showed that demographics and civic participations generally did not have a statistically significant impact on Filipino’s agreement or disagreement to environmental discourses. The paper then discusses the implications of the findings and conclusions of the study.

Description: Inspired by the emergence of the positive psychology (PP) movement, recent environmental psychology studies have identified a need for further inquiry into “positive environments” (PEs). Recognizing that PP has largely neglected the role of environmental factors in the appearance of positivity, this paper proposes the study of person–environment relations in order to explain human well-being, psychological growth, sustainable behaviors, and other psychological positive factors, in addition to studying the material and social well-being that a positive environment provides. The traditional view of environmental positivity (i.e., the environment as an inexhaustible and infinite source of resources that satisfy human needs) is contrasted against an ecological vision of PE in which the conservation of the quality of the environment is as important as the satisfaction of human needs. A definition of positive environment is presented and discussed, which conceives PE as a context that promotes individual and collective benefits and that also influences human predispositions to conserve—in the long run—the sociophysical structures on which life depends.

Description: Some researchers insist that sustainability should be represented as a continuous quest, doubting that there is the ‘right’ way to be sustainable. Acknowledging the immensity of sustainability challenges, this article takes a different perspective, arguing that without understanding of concrete barriers and seeking solutions, the challenge of addressing unsustainable practices becomes unsurmountable. This article will summarize research in sustainability literature that indicates that sustainability requires a constant human population, as well as ecologically benign method of production. This article will survey a number of helpful frameworks that address the key obstacles to sustainability, namely population growth, and unsustainable production and consumption. These frameworks are discussed in the context of business-level solutions and production systems. As illustrated by examples of best practices as well as potential pitfalls associated with each system, these systems have the potential to move the quest for sustainability beyond ‘business as usual.’

Description: In this study, Mari Luomi examines how the resource-rich GCC countries are positioning themselves in the international relations of the green economy, focusing on the UAE’s state-led efforts to acquire the means of implementation for a national green energy transition. The study addresses four questions: What strategies, external relations, and engagements have the UAE and other GCC states developed over recent years that support a transition to a green energy economy? How are these engagements providing the means of implementation for a green economy transition? Are the national policy frameworks aligned with such a transition? What lessons can be drawn from the UAE’s experience by the other GCC states? The study concludes that, as the case of the UAE demonstrates, there are multiple ways in which the GCC states can actively employ their financial resources through external engagements to support a broader national green economy vision. However, enabling environments which are crucial for directing investments into green activities, jobs and infrastructure, are only beginning to emerge, and a lot of work still remains to be done in all six states, particularly in the areas of energy subsidy reform and sustainable job creation in productive sectors. The study closes with a number of related observations and recommendations. Executive Summary The post The International Relations of the Green Economy in the Gulf – Lessons from the UAE’s State-led Energy Transition appeared first on Oxford Institute for Energy Studies .

Description: As the birthplace of the oil and gas industry, Azerbaijan’s long and rich history is intertwined with hydrocarbon production, with oil drilling pre-dating activity in Pennsylvania by 13 years. The involvement of foreign oil companies in the late 1800s, including the Nobel Brothers, resulted in the country becoming the world’s foremost oil producer at the turn of that century. The Soviet era precluded further international investment, but saw a dramatic growth in gas production commencing in the 1920s. The 1990s witnessed the return of the IOCs with the Azeri-Chirag-Guneshli field (oil and associated gas) and the Shah Deniz (gas and condensate) field developments reversing the trend of production decline and creating an export surplus in both oil and gas. In this paper, Gulmira Rzayeva provides a comprehensive analysis of the challenges which were surmounted in the development of the Shah Deniz field, not least of which related to establishing export pipelines and marketing arrangements in Turkey, and (for Phase 2) Europe. Turning to the future, the paper details the nature and estimated potential of partially developed fields, discoveries at varying stages of appraisal and prospective structures in the Azerbaijan sector of the Caspian Sea. Apart from the inevitable range of uncertainty over future production levels and timing, what emerges are the twin challenges of drilling rig availability (it being impossible to bring an assembled rig into the Caspian due to width restrictions on the Volga-Don canal) and the highly challenging sub-surface drilling conditions. The modest prospects for domestic gas demand growth and Azerbaijan’s geographic location require that any future gas field development decision will also require a degree of certainty on export infrastructure capacity to the primary target markets of Turkey and South and South East Europe. These issues are covered in detail.   Executive Summary The post The Outlook for Azerbaijani Gas Supplies to Europe – Challenges and Perspectives appeared first on Oxford Institute for Energy Studies .

Description: Since the United Nations Conference on Environment and Development in 1992 in Rio de Janeiro, sustainable development became an important issue. Sustainable development often focuses on a single sector or parameter such as tourism, energy supply, water management, different aspects of nature conservation, or economy. In this paper, we provide a comprehensive picture of the development of a region since the Middle Ages and discuss whether this development can be evaluated as socially, economically and ecologically sustainable. We carried out a combined qualitative–quantitative assessment where we use quantitative data and indicators when available, as well as literature sources and expert knowledge from the region for a qualitative assessment. We judge that generally a sustainable development in the Allgäu region can be found, although also some critical points and contentious issues exist. An overall good economic and income situation for most people, the good ecological conditions and rich biodiversity, the relatively well-established social structure, as well as the identity of the people with the region and comparatively low social discrepancy, can be positively stated. In contrast, different actual and future threats exist such as new or planned infrastructure, increasing traffic or tourism activities in certain areas that degrade habitats and reduce species richness, intensification of agriculture in certain areas, but also abandonment of agriculture in other areas, loss of traditions and customs, and declining numbers of smallholders. The objective for the region would be to minimise these negative impacts and reinforce positive trends to assure the sustainable development of the Allgäu.

Description: We present a basic theoretical framework of ethnic identity, i.e., the level of immigrant's commitment to his or her host society as well as the immigrant's commitment to his or her home society. Our model can explain the emerging empirical literature which studies the effect of the immigrants' characteristics, such as age, gender, education, religion, age at arrival, stock of immigrants in the host country, etc., on their ethnic identity (such as the Ethnosizer). In addition, this paper can be used as a basis for future empirical and theoretical research on this topic.JEL classification: F22, J15, Z13.

Description: This paper investigates the saving behavior of migrants in the UK across different dimensions, i.e., comparing temporary versus permanent migrants and migrants versus natives. Established theoretical predictions show that migrants save more when they plan to stay in the destination only temporarily as target savers. Our empirical evidence takes into account the contemporaneous choice of savings and remittances. Moreover, when comparing the saving profiles of both natives and migrants, we uncover the weight of observable socio‐economic characteristics other than income and wealth. We use the British Household Panel Survey for the period 1991‐2008. The estimation results confirm that temporary migrants have a propensity to save 26 per cent higher than permanent migrants in UK. We also introduce an index of financial capability adjusted for income as an explanatory variable and, when employing the Blinder‐Oaxaca decomposition for the Tobit model of saving choice, migrants are more affected by observable social‐economic characteristics than natives.JEL classification: F22; D91; C40

Description: Over the last 15 years, Azerbaijan has doubled its protected areas territory to almost 10 % of the country’s surface area. Although the daily management of the existing strictly protected areas continues to pose a challenge, the establishment of nine national parks has been a remarkable achievement. At present, the designation of UNESCO biosphere reserves (BR) is the expressed political will of the government. By reviewing the last 25 years of nature conservation, and, in particular, the national park programme, we present an institutional analysis for integrative nature conservation in Azerbaijan. Against the cultural, social and political background, in particular the transition of the state, the challenges for cross-hierarchical governance of protected areas are outlined at the example of a BR. We find that the implementation of the UNESCO MAB philosophy, which is based on inter alia participation by administration, local communities and rural stakeholder, is hampered by this present-day political reality. The political situation and an autocratic governance scheme put successful implementation of a “model region of sustainable development” at risk. Education and empowerment are a prerequisite for eventual success; this is true for Azerbaijan as well as for other Post-Soviet countries with strong top-down regimes.

Description: Increasing environmental issues, economic and cultural differences, the regulatory framework and the great attention to social responsibility, have forced companies to face the challenge of sustainability. Thus, the adaption of a proper marketing strategy in order to achieve a sustainable competitive advantage in the market (specially export markets) has become an important principle in accepting companies. In this regard, this study is a systematic literature review, which investigated 102 published articles in international journals between 1964 and 2015. In the literature review, the main focus was on key issues such as sustainability, marketing strategies, financial and market export performance. In this article, at first, the concept of sustainability from different aspects was collected and described. Then, external factors, such as competitive intensity, public concern, regulations, technology, cultural/social, and economic, as well as internal factors, such as managers, employees, stakeholders, affecting sustainability, were studied. Finally, adaption of export marketing strategies in order to achieve sustainability export performance is discussed.

Description: This paper describes how energy policy can be evaluated in practice. The goal is to make policy makers aware of how an evaluation can be based on scientific principles and to help economists appreciate how an evaluation can be performed if strong empirical evidence is lacking. We have built a basic evaluation framework and have applied this to a selection of Dutch energy policy instruments, namely production subsidies and their complementary non-financial instrument, DEN-B. Our evaluation criterion was effectiveness, defined as the extent to which policy instruments contribute to achieving policy goals. The evaluation was based on existing ex post evaluations complemented by interviews and other available data. We conclude that production subsidies and DEN-B were (partly) effective. Furthermore, the Dutch government increased effectiveness by reconsidering the design of production subsidies. We also formulate lessons for future policy evaluations and energy markets policies.

Description: Many developing countries like Nigeria face serious challenges with regards to the provision of public housings for their citizenry. The purpose of this research article is to establish critical success factors (CSFs) for public housing projects (PHPs) in Nigeria. The data collections were performed in Nigeria using interviews, pilot survey and a questionnaire survey. The interviews were conducted with experts in housing so as to determine the sufficiency and appropriateness of the success attributes gathered from the literature review with respect to Nigerian situation. After analysing the results of the interviews, a draft questionnaire was prepared and pretested. Following a slight revision, a final version of the questionnaire was designed. A questionnaire survey was performed in which five hundred and fifty (550) questionnaires were distributed by means of stratified sampling techniques. The respondents were construction professionals with experience in PHPs implementation in Nigeria who work in developers’ companies, consultancy firms, contracting companies or public housing agencies. Two hundred and eighty-one copies of the administered questionnaires were completed and brought back, equivalent to 51 % response rate. Structural equation modelling technique was employed in the data analyses process. The study establishes seven CSFs for PHPs in Nigeria. These factors are: (1) institutional framework for public housing, (2) availability of competent personnel, (3) effective project management, (4) good maintenance management practice, (5) appropriate design and good location, (6) effective housing finance system and (7) adequate political support. The CSFs established in this study can serve as a guide to housing policy makers, public housing developers and project managers towards successful accomplishments of PHPs in Nigeria.

Description: Since the 1970s, debates on “population growth” and “sustainability” have fluctuated markedly between pessimistic forecasts and optimistic certainties. Nowadays, they have reached a strange, comfortable illusion according to which the demographic future of our planet does not seem to be a problem at all. Nevertheless, median population growth projections by 2100 indicate that an arrest of the increase by the end of the century is rather unlikely. The future prospect is made even more critical by the fact that the increase will occur in what can be called demographic “Growing spots,” strongly opposed to just as many “Aging spots.” In these terms, therefore, the future demographic dynamics will certainly pose a challenge to the “population growth-sustainability” combination, for which it will be necessary to develop a new paradigm capable of operating in a “strong transcalar perspective,” within a global space that will increasingly acquire characteristics of fluidity and changeability.

Description: China is facing the problem of climate change, environment protection and energy security. Therefore, China has to create a low-carbon society to address them. The purpose of this paper is to make a comprehensive and in-depth analysis of China’s reality and transition to a low-carbon society. The research indicates that China’s transition to low-carbon society will inevitably meet many difficulties under the relatively backward situation of China’s socio-economic structure and technologies at the current stage. Therefore, China has to take concrete policies and countermeasures to promote its development gradually. In particular, China has to vigorously promote the innovation of low carbon system, technologies, subsidy and tax, financing and investment to lay groundwork for comprehensive development of low-carbon society.

Description: The hunting of wild animals remains a common activity in various parts of the world, especially in rural communities with poor socioeconomic conditions. To investigate patterns of mammal hunting, this study adopted a rural community located in semiarid Brazil as a model to test whether variables such as perceived abundance, activity period (day or night) and animal biomass could influence the consumption potential of mammal taxa. For this study, a checklist/interview technique using 32 photographs of mammals recorded in the region and two photographs of species that did not occur in the region, which acted as “control” species, was used, in addition to other visual stimuli and free lists. All species presented in the photographs, with the exception of the “control” species, were recognized as occurring in the region. Fourteen species were cited as being those most hunted locally. The species cited as most hunted had an average perceived abundance higher than the group of the least-hunted species. However, there was no significant relationship between hunting of a species and its locally perceived abundance. No significant difference in hunting pressure between diurnal and nocturnal species was found, nor was a relationship between animal biomass and hunting pressure observed. Our findings suggest that perceived abundance is an important factor for choosing a resource fauna, but other factors such as intended use, meat flavor and vulnerability to hunting, among others, may influence the potential use of a species.

Description: The assumptions and empirical evidence linking climate change adaptation to development cooperation have led to the emergence of a range of climate change adaptation tools aiming at improving the quality of development cooperation initiatives in times of global change. In order to assess the quality of these tools, we develop an analytic framework to critically assess the social learning and sustainable development outcomes of climate change adaptation tools. The analytic framework defines project objectives, participation typology, participation tools, participation stages, scenarios development, modelling exercises, stakeholder analysis and risk communication strategies that support quality participation outcomes.

Description: This paper addresses the requirements of electrical energy for an isolated island of Masirah in Oman. The paper studied the possibility of using sources of renewable energy in combination with current diesel power plant on the island to meet the electrical load demand. There are two renewable energy sources used in this study, solar and wind energy. This study aimed to design and evaluate hybrid solar/wind/diesel/battery system in terms of cost and pollution. By using HOMER software, many simulation analyses have been proposed to find and optimize different technologies that contain wind turbine, solar photovoltaic, and diesel in combination with storage batteries for electrical generation. Four different hybrid power systems were proposed, diesel generators only, wind/diesel/battery, PV/diesel/battery, and PV/wind/diesel/battery. The analysis of the results shows that around 75 % could reduce the cost of energy by using PV/wind/diesel hybrid power system. Also, the greenhouse emission could be reduced by around 25 % compared with these by using diesel generators system that currently utilize in the Masirah Island. The solar/wind/diesel hybrid system is techno-economically viable for Masirah Island.

Description: Industrialization is a common strategy adapted by developing countries in order to stimulate urban development and socio-economic development. Unless guided by a stringent development plan, industrialization-based urban development can lead to negative environmental consequences. This paper examines the environmental conflict that raged into an impasse between the state, society and industry stakeholders at the Map Ta Put industrial zone of the Eastern Seaboard Development Program of Thailand. Using RS–GIS tools, the study conducted a spatial–environmental analysis to elucidate the causes for the conflict and the outcome of the pragmatic approach of the state to resolve it. The study finds expansion of industries and spread of industrial air pollution beyond the buffer zone into the surrounding residential area as the main reasons for the conflict. The policy interventions by the government since 2007 were found to be ineffective to resolve the conflict. Based on the lessons learnt, the study recommends a three-pronged approach to guide similar type of industrial development toward green growth in future.

Description: Providing sanitation for water-starved areas is crucial to environmental sustainability. Composting latrines are a sustainable sanitation method since they do not require water. However, little analysis has been done on the decomposition process occurring inside the latrine, including what temperatures are reached and what variables most affect the composting process. Having better knowledge of how outside variables affect composting latrines can aid designers and users on the choice, design, and use. Detailed field measurements of pit temperature in a latrine for several months were taken with the compost being frequently mixed and moistened. Ambient temperatures and the mixing of liquid to the compost resulted in temperature increases 100 % of the time, with seasonal ambient temperatures determining the rate and duration of the temperature increases. However, compost only reached total pathogen destruction levels in 10 % of the measurements. Storage time recommendation outlined by the World Health Organization should be complied with. If these storage durations are obtainable, the use of composting latrines is an economical and sustainable solution to sanitation while conserving water resources.

Description: In 2014, there was virtually no summer in northern and central-southern Italy. Storm after storm battered the peninsula, triggering floods and landslides from Veneto to Puglia. We studied the coverage of “the year without a summer” in Italy by analyzing the content of 171 news articles from two influential online newspapers. Our software-based analysis enabled us to observe that the two newspapers hardly ever mentioned climate change in their coverage of the weather anomaly that affected Italy in the summer of 2014. This type of coverage is in line with climate science, according to which there is no evidence of a climate change-related influence on summer precipitation patterns in Southern Europe—whereas such influence has been documented for northern Europe. We compared our results with a recent paper, which documented that the same online dailies chose to represent the particularly hot summer of 2012 in Italy as a direct consequence of climate change. We corroborated this comparison also on the basis of a preliminary analysis we performed on the media coverage of the exceptionally hot and arid summer of 2015 in Italy.

Description: Sustainability indicators are well recognized for their potential to assess and monitor sustainable development of agricultural systems. A large number of indicators are proposed in various sustainability assessment frameworks, which raises concerns regarding the validity of approaches, usefulness and trust in such frameworks. Selecting indicators requires transparent and well-defined procedures to ensure the relevance and validity of sustainability assessments. The objective of this study, therefore, was to determine whether experts agree on which criteria are most important in the selection of indicators and indicator sets for robust sustainability assessments. Two groups of experts (Temperate Agriculture Research Network and New Zealand Sustainability Dashboard) were asked to rank the relative importance of eleven criteria for selecting individual indicators and of nine criteria for balancing a collective set of indicators. Both ranking surveys reveal a startling lack of consensus amongst experts about how best to measure agricultural sustainability and call for a radical rethink about how complementary approaches to sustainability assessments are used alongside each other to ensure a plurality of views and maximum collaboration and trust amongst stakeholders. To improve the transparency, relevance and robustness of sustainable assessments, the context of the sustainability assessment, including prioritizations of selection criteria for indicator selection, must be accounted for. A collaborative design process will enhance the acceptance of diverse values and prioritizations embedded in sustainability assessments. The process by which indicators and sustainability frameworks are established may be a much more important determinant of their success than the final shape of the assessment tools. Such an emphasis on process would make assessments more transparent, transformative and enduring.

Description: Kolkata, home of 4.5 million people, is generating 1112 million liters of sewage per day and facing the challenge of managing this wastewater. The 125 km 2 wide wetland on the eastern fringe of the city, popularly known as the East Kolkata Wetlands is serving as a natural sewage treatment plant for more than a century where nearly 78 % of city sewage goes through an intricately designed canal network. This wetland is a designated RAMSAR site where the sewage treatment process is a rare example of an intertwined symbiotic relation between wastewater treatment and wetland aquaculture, where livelihood dependence of the local people on sewage-fed fisheries becomes of strategic importance in sustainable performance of the system. An aggressive urban expansion in the eastern fringe of the city is disturbing this age-old eco-balance by making this sewage water pisciculture less profitable. There is push factor due to reduced attraction of the wastewater fisheries and a pull factor due to emergence of alternative livelihood options through rapid urbanization. To protect wetland in its original form, the civil society and the administrative authorities are designing active interventions. However, these are not generating expected results as these instruments are targeting to mitigate the push factor only without paying much heed to the push–pull interactions.

Description: An unmodified natural adsorbent, Xanthium Strumarium, was explored for its decoloration potential for treatment of textile effluents. Batch mode experimentation was carried out to optimize several process parameters with the well characterized adsorbent. For proper assessment of optimized pathway of adsorption, adsorption isotherms were implemented to the experimental data using nonlinear method. Apart from coefficients of determination, three error analysis methods standard error (S.E.), Chi-square (χ 2 ) statistic and residual mean square error were additionally used to determine the best fitted isothermal model for the system. Freundlich model was creditably fitted to the adsorption data with minimum errors and high R 2 values. The adsorption capacity obtained was 14.7, 15.2 and 18.7 mg g −1 at 30, 40 and 50 °C, respectively. Overall adsorption process was endothermic with positive enthalpy and entropy values. Kinetic study revealed adsorption to be a two stage process initially controlled by film diffusion followed by pseudosecond order as the rate administering step during adsorption. About 95 % decoloration was achieved in 60 min. High decoloration tendency of the opted adsorbent proved that it is an effective and cheap adsorbent for treatment of coloured effluents providing a good alternative to activated carbon.

Description: The share of electricity generation from environmentally friendly renewable energy technologies is growing in many electricity markets worldwide. The increase of intermittent supply, with low variable generation costs from sources such as wind and photovoltaic, increases the need for flexibility in electricity systems. Power systems require flexibility both in the long term (secured generation capacity) as well as in the short run (system balancing). This paper focuses on short term flexibility requirements, i.e. balancing real time deviations in supply and demand. Penetration of intermittent resources can increase the cost of balancing demand and supply as the net load has more variability compared to the load itself. In the UK, the total cost of balancing service exceeded £1 billion in 2013-14. Thus, it is important that the power systems have access to an economically efficient portfolio of flexible resources. To some extent, National Grid in the UK has already started to integrate demand side in its balancing service. For example, under the Frequency Control Demand Management (FCDM) scheme, frequency response is provided through automatic interruption of contracted consumers when the system frequency transgresses the low frequency relay setting on site. National Grid is also trying to utilise slower responding demand response for load following services. In recent years advances in the design and manufacture of intermittent renewable generation technologies has allowed these resources (for example wind turbines) to contribute to various balancing services needed by power systems. However providing some of these balancing services, such as frequency response and regulation through intermittent renewable, is more costly than using conventional generation. This research analyses whether balancing mechanisms can be adjusted to more economically accommodate increasing amounts of intermittent renewable energy sources (RES). We focus on the integration of the demand side as well as the input from intermittent RES into the balancing systems. The study investigates whether both market and product design on the procurement side of balancing mechanisms could be modified to improve flexibility sources’ integration and thus reduce balancing costs. We analyse this question comparing two major European electricity systems, the British and the German market.

Description: Recent conjecture on the potential primacy of physical environmental components in education for sustainable development (ESD) efforts serves to question the centrality of social justice education as a component of ESD. This research explores a sustainable development student’s basic knowledge of social justice conditions in their country of residence and its relationships to policy attitudes that should be of importance to ESD, including beliefs about the importance of corporate social responsibility, their endorsement of gross national product as an effective measure of progress, their overall assessment of the social fairness of current national social justice policy, and their endorsement of the goals of Occupy Wall Street. Results obtained using path-model hypothesis testing indicate that accuracy of knowledge of US standing on social justice issues is significantly related to these policy attitudes, providing support for social justice content in ESD endeavors to create students empowered for engagement in broader policy goals.

Description: This paper brings new evidence to the existing literature on earnings differentials and returns to human capital for immigrants and natives. It is the first paper analysing this topic using data drawn from the Italian Labour Force Survey, a large nationally representative dataset. We show that returns to human capital are considerably lower for immigrants as compared to natives and that there is no return to pre-immigration work experience, suggesting imperfect transferability of human capital. In the second part of the paper we explore models of occupational attainment among immigrants and the native born. Our findings suggest that, contrary to what is observed for natives, immigrants’ human capital does not contribute to getting access to high-paying occupations.JEL classificationJ31, J24, J61, F22

Description: Motivations for migrants to return clearly change with integration, but the time-changing aspect of return migration has received little attention in the literature. This paper studies how migrants’ preferences for the home country change with intermarriage, i.e., marriage to a spouse from the host country. Specifically, I analyse the association between intermarriage and three outcomes related to migrants’ home country preference – intentions to return, remittances sent and actual return – using German panel data (SOEP) for the period 1984–2012. The results reveal a negative association between intermarriage and home country preference that is moreover stronger for female than for male migrants. However, some of the effect seems driven by selection since the relationship gets weaker once I control for person fixed effects.Keywords: Return migration, Intermarriage, Intentions to return, Remittances.

Description: Water scarcity at an alarming rate has been a limiting factor for sustainable agriculture in arid and semi-arid environments of the world. It has resulted in a number of problems such as poverty and food insecurity among farm households. Therefore, building and improving resilience, as a way to mitigate the impacts of water scarcity, is important for farm households. But one of the significant steps for planning to improve farm households’ resilience under water scarcity is investigation of the current level of resilience of these households and understanding their variances. Therefore, this study offers a classification of farm households’ diversity based on resilience. Primary data were collected from 260 randomly selected farm households in 21 villages around Parishan wetland, Iran. Farm Household Resilience Scale was used to measure resilience. Cluster analysis suggested three groups: highly, medium-, and low-resilient farm households. The results of comparing three groups revealed that highly resilient farm households characterize with higher risk management, more agricultural water security, more positive psychological traits, and better knowledge management. Also, they had better water quality, attended more agricultural extension activities, and used modern irrigation systems. Farm households’ resilience map using GIS software illustrated that there is a relationship between resilience and farm location from the wetland. The findings of this study could be used by planner and policy-makers to improve farm households’ resilience in arid and semi-arid environments. Improvement in knowledge management system is recommended as one of the most effective policy instruments in building resilience.

Description: In the Blue Nile Basin of Ethiopian highlands, rainfall distribution is extremely uneven both spatially and temporally. Drought frequently results in crop failure, while high rainfall intensities result in low infiltration and high runoff causing soil erosion and land degradation. These combined factors contribute to low agricultural productivity and high levels of food insecurity. Poor land management practices coupled with lack of effective rainwater management strategies aggravate the situation. Over the past two decades, however, the Government of Ethiopia has attempted to address many of these issues through a large-scale implementation of a number of soil and water conservation measures. Despite the success of interventions, uptake and adoption remains low. The conceptual framework of this study is based on the premise that farmers are more likely to adopt a combination of rainwater management technologies as adaptation mechanism against climate variability and agricultural production constraints. This contrasts the previous work that typically examined a single technology without considering the interdependence between technologies. Data used in this study come from household survey in seven watersheds in the Ethiopian Blue Nile Basin. A multivariate probit model was used to account for the potential correlation and interdependence of various components of rainwater management technologies. Our results suggest that rainwater management technologies are related with each other; hence, any effort to promote the adoption of rainwater management technologies has to consider such interdependence of technologies, or failure to do so may mask the reality that farmers face a set of choices in their adoption decisions.

Description: The code for sustainable homes (CSH), which came into existence in 2006, has not yet been investigated to determine whether its rate of adoption is on course to meet the UK government’s 2016 target for full implementation. Therefore, the aim of this investigation is to ascertain the level to which CSH has been implemented and the barriers preventing this. A questionnaire survey was sent to 71 of the Home Builders Federation (HBF) member organisations in the UK, to gauge and ascertain the following: the barriers to the implementation of CSH; the implications of implementation; and the general awareness of CSH amongst practitioners. The results from the analysis of the survey reveal that full implementation by 2016 appears a rather difficult target, as factors like economic downturn are hitting HBF and similar organisations quite hard. However, a government-driven injection of sustainable schemes is helping to bring back confidence to house builders, while also enhancing the way that barriers are handled within the industry. The key findings of the literature review identify barriers preventing the housing sector from achieving zero carbon homes by 2016. These include cost, and legislative, cultural and technical barriers, and are concordant with the results from the data obtained during the primary research. The analysis suggests that with the current trend, achieving full implementation will be difficult. However, comments made by some practitioners appear to suggest that the appointment of a CSH champion for implementation would accelerate the process of full implementation and that the target could be reached by 2016.

Description: In this article, the attempt is made to address regime interaction in environmental governance by emphasising human livelihood action as a causal factor in this interaction. The paper elucidates how governing human behaviour on environmental resources is a process of interaction between different environmental governance regimes. With a qualitative case study of sand winning in the Dormaa Municipality and Dormaa East district in midwestern Ghana, the article shows strategic ways landowners and sand vendors pursue and legitimise their livelihood, and in the process bring about interaction between a tax regime on sand winning and the customary property rights regime of the area. It notes therefore that regime interaction is not only caused by differences in the structure of institutions, but also through the ways humans act to pursue their livelihoods. Based on this, the paper highlights the need for consciousness towards livelihoods of people and how such livelihoods are pursued as important contexts within which regimes function and interact. In this way, environmental governance can be more responsive to the well-being of people.

Description: This paper identifies the factors that influence perception of program benefit of the recipients when a hypothetical public program is implemented in reality. We compare pre- and post-program Willingness to pay (WTP) estimates for improved waste management in Bally Municipality, India, and find that post-program predicted WTP falls by more than 50 % even when if there are substantial improvements in urban environment. We show that this can be explained by the relative strength of leisure cost of effort to participate in the waste management program vis-à-vis the benefit derived from cleaner environment. Our study shows that mismatch between expected and offered service attributes might be a source of disutility and could also dampen households’ perceived value of the program benefits. In such cases, the reduction in WTP might act as an indication of the local bodies regarding the scale of outreach and expansion of the program needed to finance the operation and maintenance expenses by supplementing the property tax bases through user fees.

Description: The sharp decline in the oil price has altered the economic outlook for the GCC. After a period of sustained real GDP growth, which averaged 5.8 percent during 2000-2011, the IMF projects growth rates to slowdown to 3.4% in 2015 and 3.3% in 2016. Also, after achieving large fiscal surpluses that averaged 12.2% of GDP during 2000-2011, the GCC countries are projected to run fiscal deficits of 6.3% and 4% of GDP in 2015 and 2016. The change in the macroeconomic outlook is already having its impact on key sectors. The region’s stock markets have tumbled from their high levels reached in the first half of 2014, local banks are reining back on their lending, and the confidence of the private sector has taken a strong hit. But when compared to their counterparts in other parts of the world, the GCC oil exporters are in a much better position to withstand a period of lower oil prices. Key Gulf oil producers – such as Saudi Arabia, Kuwait, and the UAE – have low foreign and domestic debt. Also over the last few years, these GCC producers have accumulated large reserves of foreign currency, which provides their economies with a large fiscal buffer. While GCC countries have become more resilient over the years (thanks in large part to their ‘prudent’ counter-fiscal policy and sustained period of high oil prices), deeply rooted structural challenges remain. This paper will explore some of these structural challenges and how GCC governments are most likely to respond to these challenges.

Description: This book will explore how far the European Union can go towards its new goal of forming its 28 member states into an Energy Union, in the belief that this will deliver energy affordability, security and sustainability. Situating today’s challenges in a broad historical sweep of EU policy development, it will deal in turn with the growing tension of liberalisation v. state intervention and subsidy in markets, the revolution in the electricity sector, and the need for a new market design and demand response to complete that revolution successfully. It will also examine the external context for Europe’s go-it-alone decarbonisation effort, specifically the cost impact on the competitiveness of energy-intensive EU industries with the rest of the world and the energy security risks of dependence on Russian gas in particular. The book will be published early autumn 2015. The post Europe’s long energy journey: towards an Energy Union? appeared first on Oxford Institute for Energy Studies .

Description: Global crude oil prices has plunged over 50% from its peak at $115 per barrel in June 2014 to around $50 per barrel in January 2015. In response to the falling oil price, the National Development and Reform Commission of China has lowered the retail prices of gasoline and diesel twelve times in a row since June 2014. The most recent retail prices for 90# gasoline and 0# diesel are 36% and 39% lower than their price levels six months ago, respectively. The plunging price of oil can have both direct and indirect impacts on the Chinese economy. For instance, it can reduce the costs of industrial production and residential consumption, which can have a direct impact on the producer price index (PPI) and consumer purchase index (CPI). In addition, the interconnection of industries in an economy means that the changes in oil price can also have indirect impacts on the price levels of industries that are not closely related to the oil industry. Some discussion is taking place around the issue of China’s economic development can benefit from the falling oil prices. However, there lacks sophisticated analysis on issues like to what extent the falling oil price could influence the Chinese economy and which sector is most likely to benefit from the price fall. This study aims to estimate the impacts of falling oil price on the general price levels (including CPI and PPI) and on industrial price levels in China. The Leontief Price Model (LPM) is used in this study. LPM is also known as cost-push input-output price model that captures the interconnections between different industries. The model has been used in the estimation of the impacts of price changes in an industry on the other industries and the economy.

Description: The integration of large share intermittent renewable resources into countries’ energy mixes necessitates more operational flexibility in their power systems. By increasing flexibility, power systems become more resilient to the inherent uncertainty of renewable energy, thus becoming capable of operating at different generation levels and smoothly shifting among them. (IEA, 2014). Although flexibility has been typically associated with rapidly dispatchable power plants, alternative resources, such as grid interconnections, storage capacity and demand-side integration are also relevant to facilitating flexibility. The future degree of flexibility required and the need to diversify the flexibility resource portfolio (in order to reduce costs and improve reliability), will shape the future role of demand side programmes. It is envisaged that in the case of Great Britain, demand side participation along with pumped storage and gas turbine plants will constitute the main sources of operational flexibility for its power system (Pöyry, 2014). In fact with ICT advancement, regulation services and contingency reserves, through automated dispatchable demand side resources, are no longer a dream. There is also the possibility of integrating slower responding demand control programmes to provide longer load following services. From an economic perspective, providing substantial amounts of flexibility to the system is costly as it increases the cost of wear and tear, fuel and the operation of flexible generation units. Additionally, it exposes the consumers to significant disutility when it is provided through demand response. Therefore electricity markets need to incentivise the resource owners to offer flexibility services. This research answers the fundamental economic question of what incentives are needed to enable flexibility in electricity markets especially in the context of demand side resources. Our contribution is: i) to explicitly model contractual relationships arising in different forms of flexibility trading, under the presence of multi-dimensional asymmetric information, ii) to model flexibility as a related but distinct commodity with three features of start-up time, capacity and duration and iii) to take a microeconomic approach by modelling individual decisions by agents involved in the exchange of flexibility.

Description: Eco-certification has been used as a tool to mitigate adverse effects of aquaculture production and might thus be understood as a private approach to sustainable ecosystem management. In production forests in Ca Mau, Vietnam, where mangrove have suffered degradation despite legal protection, different projects have targeted reversing this trend by means of private certification using the ‘Naturland’ organic standard as a reference. So far the outcomes have, however, been proven unsatisfactory. With the aim to better understand the reasons for these poor outcomes, a survey of forty households was conducted in a production forest in Rach Goc commune, Ngoc Hien District. We evaluated farmers’ perceptions on mangrove management, the drivers guiding shrimp farming, and whether there was a difference between participants and non-participants in a former ‘Naturland’ organic project. To complement the survey, a range of stakeholders involved in shrimp value chains were interviewed to better understand the terms and benefits of certification. The results of this survey suggested that, when applied to shrimp–mangrove farming systems in production forests in Ca Mau, ‘eco-certification’ and associated benefits are not very satisfactory. The survey results revealed that certified farms do not show significant differences to non-certified farms in terms of social and environmental benefits. As far as the implementation process was concerned, the survey results showed that a failure to integrate local farmers as participants consequently resulted in households becoming ‘objects’ for certification and not project partners with equal weight and power. It appears that rather than being a tool for improvement, ‘Naturland’ certification for shrimp–mangrove farming systems in Ca Mau’s production forests has become an end in itself.

Description: This study investigated methods for identifying daily incidence rates for bird species. It focused on relationships between incidence rates, site and season. We used sightings of 23 common resident species routinely reported every month from January 2004 to December 2007 at seven wetland locations in the Thale Noi non-hunting area of southern Thailand. Our findings revealed that the log-linear model gives a quite satisfactory fit, so it appears a suitable type of model for bird abundance. On taking logarithms of the incidence rates though, the zero counts must be replaced by an appropriate constant. Our model suggests that Cattle Egret ( Bubulcus ibis ) was found at the Thale Noi non-hunting area with the highest incidence rate. In contrast, we found a low mean of model outputs for Lesser Whistling-Duck ( Dendrocygna javanica ) relative to the mean in the data, and this species was not observed on at least 25 % or 3 days per year. These data had a low number of zeros and a large number of various species. Therefore, we recognize a remark on “what is being counted” that it is important to reasonably explain the species abundance in terms of statistical and ecological approaches.

Description: This paper examines consumer attitudes and behavior on the use of plastic and cloth bags in Eskişehir, Turkey. To this end, a structural equation model is proposed. Environmental consciousness regarding the use of plastic bags, social pressure, support for the banning of plastic bags, the intention to use cloth bags and behavior to reduce plastic bag use are employed as latent variables in the model. The intention to use cloth bags and the behavior to reduce the use of plastic bags are defined as endogenous latent variables in the structural model. In the conclusion of the study, it is identified that consumers who are environmentally conscious and feel under social pressure, tend to reduce the use of plastic bags and switch to using cloth bags.

Description: The occurrence of arsenic in drinking water and its detrimental effects have drawn much attention in recent years. Several studies have been conducted in the deltaic plains of River Ganga, NE part of the India, and in other countries, but no systematic study was conducted in South India on occurrence of arsenic in groundwater. The main aim of this study is to determine the level of arsenic in groundwater and to understand the relation with other geochemical parameters of groundwater in the south-eastern coastal aquifer at Kalpakkam region, India. This region is represented by three different lithologies, viz. charnockites, flood plain alluvium and marine alluvium. Twenty-nine representative samples of groundwater were collected and analysed for major ions, metals and isotopes such as 2 H and 18 O. In addition, geophysical method was also attempted to understand the subsurface condition. The spatial variation in arsenic (As) indicates that higher concentration was observed around the landfill sites and irrigated regions, which was supported by geochemical, statistical and isotopic inferences. The variation in the As with depth, lithology and sources has been clearly brought out. Though the values of As does not exceed the drinking water permissible limit (10 mg/l), it has reached a near permissible level of 8.7 ppb. Hence, it is essential to understand the geochemical behaviour of As for a proper future management of the water resource in the study area.

Description: Irrigation is indispensable to overcome insufficient rainfall and to achieve a stabilized yield for tea production. As the severe scarcity of water resources because of climate change, water conservation through efficient irrigation has turned into a vital strategy for tea sector in solving this rising challenge. This paper analyzes irrigation water use efficiency of small-scale tea farms in Vietnam and identifies its determinants applying stochastic frontier analysis. Results showed that under decreasing returns to scale, the mean irrigation water use efficiency was 42.19 %, indicating the existence of substantial water waste. If farmers become more efficient in using water, saving 57.81 % of irrigation water is possible unaccompanied by reducing the observed output. The factors affecting tea farms’ irrigation water use efficiency were investigated by Tobit model. Gender, water shortage awareness, soil and water conservation practice, off-farm income share, extension services access and well water utilization showed significant influence on the efficiency of irrigation water. The study’ results provide insights to policymakers in implementing better water resource management amid climate change.

Description: While the goal of reducing environmental impact has become an urgent imperative for Chinese leadership, the central and potentially competing objective for policy makers and planners remains economic growth and job creation. This paper systematically examines the perceived trade-offs between pollution control regulation and employment at the microeconomic and macroeconomic scale. We synthesize the theoretical literature on the employment impact of pollution control regulation at the firm, industry, and economy levels and summarize the theoretically sufficient conditions for employment-enhancing regulation. The paper examines the US experience with the impact of pollution control on job growth in the 1980s and 1990s and draws out the mechanisms through which job growth and pollution control can be congruent, examining their adaptability to the Chinese context. Specifically, this paper highlights the importance of targeting regulations toward sectors where labor costs represent a small portion of overall costs or sectors with low labor intensity. We demonstrate that in the Chinese context, a transition to an economy with a higher proportion of tertiary output is likely to facilitate a joint strategy of stringent pollution control combined with job growth.

Description: The present study was conducted to determine the physico-chemical properties and heavy metal contents in soils under three land uses (agricultural, riverbank and roadside) from areas situated around rivers (Beas and Sutlej) in Punjab, India. Heavy metal contents in wheat samples (grain and fodder) growing in the area were also analyzed in order to find out potential human health risk through wheat consumption. The studied soils under the three land uses were found to be basic in nature with sandy texture, low soil organic matter and other soil nutrients. Comparatively higher amounts of soil nutrients were observed in soils under agricultural land use as compared to riverbank and roadside land uses. The amounts of heavy metals (Cr, Cu, Co and Pb) analyzed in soils were lower than the various national and international maximum permissible limits, but heavy metal contents observed in wheat fodder samples exceeded the maximum permissible limits for fodder. The soil-to-plant metal bioaccumulation factor was found to be highest for Cu (3.812 for soil–wheat grain and 1.874 for soil–wheat fodder), which showed the bioaccumulation of heavy metals from soils to crops, and the wheat straw-to-grain translocation factor was found to be highest for Co (4.375). The hazard index calculated to assess non-carcinogenic health risks was found above 1 for children, meaning that the wheat grains can pose health risks to children.

Description: We propose a theory of free movement of goods and labor between two economies in the presence of moral hazard. Each country produces two final goods where the productive efforts of workers cannot be perfectly observed, or verified only in the complex industry. We show that national institutional quality and the system of the early childhood care and education determine the pattern of international trade. However, individuals’ decisions to emigrate depend only on the national institutional quality, where the country with more developed institutions serves as the host country of immigrants. We conclude that international labor movement promotes international trade.JEL classification: B52, I21, F10, F16, F22, J24.

Description: The aim of this paper was twofold: on the one hand, we analyse the results achieved in terms of percentages of separate collection in Italy by testing the effectiveness of Legislative Decree 152/2006 in improving the separate collection process; and on the other hand, we investigate on some of the factors, related to the sociocultural local context, that could explain the different impacts of the law in the three macro-areas considered (North, Central and South Italy). To this purpose, an econometric analysis on the Italian regions for the 1996–2013 period is performed, comparing the period before (1996–2006) and after (2006–2013) the date of entry into force of the new law. The results show the effectiveness of Legislative Decree 152/2006 in promoting separate collection, although a regional difference in terms of separate collection rate is observed. Northern regions proved to be more dynamic and reactive to the above-mentioned legislation, while Central and especially Southern regions achieved poorer results in moving to higher separate waste collection rates. Finally, our work provides evidence on some local factors that may have hampered an effective policy implementation in Southern regions, among them, the presence of criminal activities and the lack of citizen participation in politics.

Description: The objective of this is to analyse how contractual stabilization devices have evolved since the late 1990s, based on a survey of 20 countries and a review of the literature and evidence on stabilization clauses. Although fiscal stability is a commonly cited attribute of a desirable upstream petroleum regime, one of the commonly observed features of existing regimes is the lack of stability. The paper studies the major triggers that push host governments to revise the fiscal terms to which they originally agreed with investors; amongst various economic and political factors, one of the obvious drivers is the oil price. Chasing the price of oil, however, is a burdensome and inefficient strategy, as oil is an internationally traded commodity where short-term price volatility is the norm. The paper’s three broad conclusions include: First, classical stabilization models have not been successful in practice; Second, the more modern clauses are more likely to treat changes in fiscal terms symmetrically, and may be equally beneficial to governments and oil companies; Third, modern stabilization clauses can allow policymakers to consider the overall tax system and its impact on revenue and growth, without worrying about the specific impact on the oil and gas sector, and without penalizing investors in the sector. Fiscal stability clauses in developing countries will remain a key feature of contractual agreements and oil and gas laws for years to come. However, the effectiveness of the more modern clauses in achieving the desired outcome remains as questionable as that of previous stability models, particularly in countries which continue to lack the administrative capability to enforce these mechanisms, and where government policy in general and investment laws and the judiciary in particular lack credibility.

Description: Brazil is considered one of the world’s leading producers of biofuels given the predominance of ethanol fuel in its energy matrix. However, despite the prominence of Brazil in ethanol production, the vast majority of biodiesel production plants in Brazil use methanol instead of ethanol as the alcohol for transesterification reaction, as is generally the case in the rest of the world. The aim of this paper is therefore to examine the transesterification process in the Brazilian biodiesel production in terms of sustainability. In this regard, it was necessary to evaluate the way in which the industrial process is currently carried out, the role of government incentives or subsidies for the use of ethanol to produce biodiesel, and the investments of companies in technology development for the same purpose. This study presents indications that the development of the biodiesel market in Brazil is still oriented toward a production model which is inconsistent with the environmental and social aspects of sustainability.

Description: The term sustainability invites interest in the main factors that affect the deterioration of natural resources. Different hypotheses have been put forward concerning the relationship between water and its effect on different economic sectors. Several questions can be asked here, for example: Does a higher water withdrawal for one sector mean that this sector is adding more to the GDP or is it a sunk cost (it is the cost that should be ignored compared to the benefit of water withdrawal for an individual economic sector) compared with the benefits to the economy? Do social factors affect water withdrawal more than economic factors or are they both impacting equally? We aim to answer these questions and to shed light on different socio-economic factors that affect water withdrawal in different economic sectors. This study investigates, in depth, the interaction between humans and the environment and can be useful in monitoring the direct effect on water withdrawal from agricultural and non-agricultural sectors and on different national economic variables that act as an indicator for economic development and growth. We used simultaneous equation models in our analysis, both the three-stage least squares and the two-stage least squares to explore the relationships. For more credibility, we run the fixed and random effects of 2SLS. Our results showed the influence of trade openness and economic growth on water withdrawal for different economic sectors, and the effect of an increasing demand for water for non-agricultural purposes, which adds pressure on the agricultural sector and eventually may lead to rising food prices.

Description: This paper argues that electricity markets in Europe are broken. The increasing penetration of subsidised, zero marginal cost, intermittent generation has distorted prices to the extent that they can no longer give effective signals for investment or operation. The problem is increasingly being recognised but there is no consensus on the solution. The paper considers a number of options; it concludes that a serious debate needs to get under way now if we are to develop sustainable markets for a low carbon future.

Description: The increasing dominance of natural gas in power generation in the UK since the 1990s has led to growing interdependence between its gas and power sectors. From the perspective of the power sector, the security of supply of the natural gas industry has implications on the security of supply of the power industry. Following the gas sector’s perspective, demand from the power sector is more uncertain than other types of natural gas demand, posing challenge for the long-term contracting of supply and planning of infrastructure. Given this interdependence, only considering one of the industries in designing and evaluating energy policies to fulfil the UK’s energy agenda can lead to skewed perceptions and unintended consequences. This paper seeks to explore the impact of proposed regulation targeting energy security and sustainability on the extended gas-to-power supply chain, through scenario-based simulation using a System Dynamics (SD) model. The SD model is scoped to focus on industry agents that participate in the gas and power wholesale markets. The expected outcome of this research is an improved understanding of the nature, strength and dynamics of interdependencies between the investment decisions of the UK industry in power generation, gas production, pipeline/LNG terminal construction, under demand and global energy market uncertainty. The post A System Dynamics model of gas and power interdependence: the case of the United Kingdom appeared first on Oxford Institute for Energy Studies .

Description: In the present paper, the optimum design of a PV system used to operate a water pumping system was determined for Oman. The system design focused on the environmental conditions of Sohar city. The implementation and measurement of the designed system are presented to prove the effectiveness of the proposed system. The results show that the system can provide the required power at peak hours, leading to a substantial reduction in the sizing of the PV system. Consequently, the investment capital costs 2400 USD, and the cost of energy is equal to 0.309 USD/kWh. Furthermore, the results indicate that the system annual yield factor is 2024.66 kWh/kWp and that the capacity factor is 23.05 %, which is encouraging since the latter is typically 21 %. The system capital cost and the cost of energy are worth comparing to a diesel generator. A comparison is made between the proposed system and several others in the literature. The comparison indicated that the system cost of energy is promising.

Description: This study investigates the nature of the empirical link between an individual’s well-being and their carbon footprint. It employs a novel approach matching data from the Household, Income and Labour Dynamics in Australia survey, to household expenditure and greenhouse gas-based carbon footprints. The carbon footprints are calculated using environmental factor multipliers from the detailed and globally integrated multi-regional input–output (MRIO) tables provided by the Eora MRIO database. The results indicate that higher carbon footprints are associated with marginally lower levels of well-being. This relationship appears to be linear. Furthermore, this relationship does not differ greatly for individuals across the well-being distribution. The findings of this study both: (1) add to the body of knowledge on the link between carbon footprints and well-being; and (2) provide policy makers with evidence and strategic guidance on the well-being implications of mitigating carbon footprints.

Description: Forestry activities may be important complements to a farmer’s income within the context of agricultural economics, or autonomous production, with determining factors upon rural dynamics and sustainable development. Taking these ideas into account, the objective of this study was to analyze the importance of forestry for sustainability in Portugal, namely in rural regions, comparatively with the context verified across other countries in the European Union. For this, data from the Eurostat (Several statistics. European Union Statistics, Luxembourg, 2015 ) for the European countries were used, over the period 1990–2014, and for variables that allowed to capture the interrelationships among forest indicators and economic, social and environmental variables. This statistical information was analyzed from a descriptive perspective and using the pairwise correlation matrix (complemented with the Granger causality Wald tests), through the Stata (Statistics/data analysis. StataCorp, LP, College Station, TX, 2015 ) software, to understand the relationships between the different indicators. As a main finding, it is worth referring that Portugal has had, in this period, a small impact on the European Union forestry conjuncture, but with great potential, namely in terms of agricultural and rural economic sustainability.

Description: Currently, energy consumption for cooking in rural households of India is mostly based on fuelwood used in traditional stoves. This paper presents results of a study carried out in a forest fringe area of India on cooking energy use. The concept of calculating levelized cost as cost per unit of useful energy is applied on source–device combinations of cooking and validated in Bargaon Community Development Block of Sundergarh District in Odisha, India. About 92 % of the households in the study area use fuelwood as the only energy source for cooking; the total use of fuelwood for only cooking, in the Block is nearly 1.8 times the total sustainable wood supply showing an urgent need for promoting alternative cooking energy options. This paper also presents an assessment of different cooking options in terms of cost per unit of useful cooking energy. LPG, biogas and gasifier stoves are found to be far too expensive for the local people. Briquette-fired improved stoves appear to be a promising cooking energy option in the study area. Government support and intervention are recommended for promoting this option.

Description: Tehran metropolitan region (TMR) has experienced rapid urbanization in the last few decades. This accelerating urbanization trend mainly arising from high natural population growth and rural–urban migration along with rapid socioeconomic changes formed unplanned and uncontrolled urban expansion in peri-urban areas and resulted in degrading environmental quality and considerable changes in the urban landscapes of the TMR. Thus, the main objective of this research is to model spatial pattern of urban growth in eastern corridor of TMR using GIS-based SLEUTH model and the prediction of future developments of the region from 2014 to 2060. The SLEUTH is one of the most powerful models for urban growth modeling. This model analyzes the spatial pattern of urban growth based on historical data obtained from satellite images of 1987, 2003, 2011, and 2014. The results indicate that the most important factors affecting the urban growth are slope resistance and road gravity. The slope resistance is the highest coefficients value, which illustrates the limiting influence of the slopes on general trend of urban growth in eastern corridor of the TMR. The road gravity stands in second place where it displaces orientation of linear form of outlying pattern alongside the transportation network; it represents that the main pattern of urban growth in peri-urban areas of the region have a linear nature and edge expansion due to slope resistance and road-influenced growth, while spread, diffusion, and breed coefficients display low probability of new spreading center and spontaneous growth in the study area. In addition, the prediction of urban growth for 2020–2060 revealed that urban expansion which was 41,500 ha in 2014 will increase to 179,400 ha in 2060 with noticeable growth rate of 145.6 %. Comparing study area and other researches indicate that the urban growth happens in high rate in eastern corridor. One of the main reasons of this growth goes back to the formation of the second homes for residents of Tehran metropolitan city.

Description: Images in children’s books can leave a more lasting impression in young learners’ minds than text. Therefore, it is important for children’s books to use images as a teaching tool, especially regarding global issues such as environmental sustainability. This study examined how the images in nonfiction children’s books approach the topic of sustainability and whether these images support the overall goals of environmental education. We selected seven easy-to-access trade books which yielded 384 images for analysis. Two coders analyzed the images according to the following categories: (a) gender and age, (b) actions of people, (c) depictions of nature, (d) depictions of objects, (e) structures, and (f) habitation. Results show that nearly half of the images (48 %) depicted non-natural objects (16 %) or humans (31 %). One half of the images portrayed humans as consumers. Gender bias was evident, with 33 % of females portrayed as consumers and only 16 % of males portrayed as consumers. Similarly, 12 % of the images with males showed them engaged in recycling behavior, while only 4 % of the images showed females recycling. Of the 32 % of images depicting nature, individual plants rather than ecosystems were portrayed. Depictions of man-made systems predominated the images, a surprising finding. No images established the connection between consumerism and the depletion of natural resources or pollution, and further sustainable actions or lifestyles were not portrayed, implying that consumption is a societal norm. We conclude with recommendations for the use of images in children’s literature focusing on environmental education and sustainability.

Description: In emerging economies, recycling provides an opportunity for cities to increase the lifespan of sanitary landfills, to reduce the costs of solid waste management, to decrease environmental problems from waste treatment by reincorporating waste into the productive cycle and to protect and develop the livelihoods of citizens who work as informal waste pickers. However, few studies have analysed the possibilities of and strategies for integrating the formal and informal sectors in solid waste management for the benefit of both. This integration is the key, especially in developing countries, to understanding how the recycling population can develop a business despite their social and economic limitations. The aim of this study was to perform a strength, weakness, opportunity and threat (SWOT) analysis of three recycling associations in Bogotá with the aim of examining and understanding the recycling situation from the perspective of members of the informal sector in their transition to becoming authorised waste providers. This issue has rarely been studied in the context of developing countries. The data used in the analysis are derived from multiple sources, including a literature review, Bogota’s recycling database, focus group meetings, governmental reports, national laws and regulations and interviews with key stakeholders. The results of this study show that as the primary stakeholders, the formal and informal waste management sectors can identify the internal and external conditions of recycling in Bogotá. Several strategies were designed based on the SWOT analysis. The participation of recycling associations is important in the design and application of waste policy, the consolidation of recycling through an effective business model, promotional programmes for social inclusion and the development of new transformation processes and technologies to valorise recycling materials. In conclusion, recycling associations can become authorised waste providers through a profitable business that increases recycling rates to create a productive process from waste during the generation of new materials and to decrease environmental problems while improving the welfare and living conditions of recyclers. These findings are important for Bogotá to advance and promote recycling as a key strategy for integrated sustainable waste management in the city.

Description: Being located in an urban-coastal coupled system, the Hashtpar City is one of the most attractive areas for urban construction, tourism, agricultural activities and environmental protection in northern Iran. To resolve the issues between land developers and environmental conservation agencies, we conducted a scenario-based urban growth allocation procedure through the SLEUTH model. The scenarios consisted of ‘business as usual’, ‘managed urban growth’ and ‘environmentally sound growth’ that were introduced by modification of model parameters and exclusion layer. The resultant urban growth arrangements were compared for composition and configuration attributes of landscape patterns. According to the results, the pattern of urbanized lands under managed urban growth option demonstrated better connectivity and compactness of urban patches, while the two other scenarios generated a highly fragmented pattern. The managed urban growth can be considered as a compromised solution between other scenarios since it simultaneously takes into accounts both developers and environment protectors points’ of views. On this basis, a combination of centralized and decentralized urban land use planning is a recommended strategy for our urban-coastal environment to fulfill the purposes of a sustainable development process. The findings of the present article suggest that further expansion of the major urban core in the targeted area should be prohibited since it can lead to an urban patch with considerable physical size and noticeable ecological footprint.

Description: The objective of this study was to determine the main patterns and factors influencing food transition in riverine people in the Brazilian Amazon. Through interviews with a semi-structured questionnaire, we inferred their food habits and provide information about general demographic, socioeconomic, resource use and environmental context. Data from the questionnaires were categorized and analyzed using a logistic regression model to assess the relative influence of socioeconomic and environment factors on the local diet. Based on a logistic regression data analysis, it was found a greater consumption of processed food significantly associated with multiple factors such as market participation, sex (female and male), government aid to forest conservation and environment context (upland and wetland). Although the local diet is composed mainly of local resources such as fish and cassava flour, increasing incomes due to direct government subsidy programs and marketing of cassava flour have influenced these local practices and habits. Through the analysis of factors influencing food transition, it was possible to evaluate those having the greatest effect on this Amazon region and propose an alternative method to subsidy food policy grounded in local opinion surveys.

Lack of timely and accurate information on climate and prices can lead to inefficiencies in the production, harvesting, and commercialization of agricultural products, which in turn can affect farmers’ revenues and well-being. We did a Randomized Controlled Trial (RCT) experiment with 500 small-scale farmers in a rural area of Colombia where there is nearly full mobile phone usage and coverage. Treated farmers received around 8 text messages per week with prices in the main markets for crops grown in the region, and customized weather forecasts. Compared to a control group, we find that treated farmers were more likely to report that text messages provide useful information for planting and selling, and more likely to always read their messages, indicating an increase in appreciation and use of this type of technology. We also found heterogeneous effects by farmer size. Smaller farmers try to make use of the intervention by planting more crops for which they have price information. Larger farmers seek new markets and increase conversations with other producers. Despite these positive effects, we do not find a significant difference in farmers reporting a price, price differential with the market price, or sale prices received. Our results indicate that farmers are amenable to learning and using new technologies, but that the introduction of these technologies do not always translate into short-run welfare improvements for them. Given the increased interest in incorporating information and communication technologies into agriculture, our findings indicate that prior to a large-scale implementation it is necessary to better understand what prevents farmers from more directly profiting from this new information.〈/p〉〈/div〉 〈/div〉

This is due to the fact that results from different studies are not consistent, or even contradictive, which indicates the fact that the evaluation criterion itself has a great effect on the performance of the model.〈/p〉 〈p〉To explore the effect of different evaluation criteria on the performance rating of the models, four evaluation methods are applied in this paper: diffuse irradiance on facades with respect to sky condition, diffuse irradiance on facades with respect to orientation, diffuse irradiance distribution among sky dome with respect to sky condition and diffuse irradiance on buildings in obstructed environment. Based on a statistical test on available data, Igawa model is considered to be the most accurate and appropriate model for urban and building energy simulation. Besides, an evaluation criterion appropriate for screening sky diffuse models for urban and building energy simulation is proposed. Furthermore, potential errors that may occur in the measurement and the corresponding quality control is presented.〈/p〉 〈/div〉

Chandrasekharam〈/p〉 〈h5〉Abstract〈/h5〉 〈div〉〈p〉Sustainable conservation of natural resources has become a primary concern for urban cities, globally as they are centers of consumption and economy. Due to population growth, cities depend more on imports of food, energy, water, and services from all over the globe, and consume more virtual water than direct water, because of their food habits and lifestyle. Most of the imported goods are water intensive and pose challenges in tracing the source of virtual water. The goal of this research is to develop a general framework to assess the water footprint (WF) of a typical city in India using existing databases. A consumer-centric approach has been adopted for assessing WF in Hyderabad Metro Development Area (HMDA). The variation of the WF across economic classes of consumers is also analyzed. The WF is estimated based on four broad categories: 1) food consumption, 2) fossil fuels based energy, 3) electric power, and 4) direct water. Average WF of HMDA region is 1041 m〈sup〉3〈/sup〉/cap/year (2852 LPCD), in which 70% (1986 LPCD) of WF was consumed by food, 25% (744 LPCD) by electric power, only 4% (121 LPCD) is from direct water consumption and surprisingly the contribution from fossil fuel WF to total per capita WF of HMDA area is less than 1%.〈/p〉〈/div〉

In this study, an index system has been established and visualized through a Geographic Information System, for revealing both temporal and spatial characteristics of district power loads caused by heating/cooling systems, including load level and fluctuation characteristics, spatial distribution of electric loads, and load coupling relationships between individual buildings and the district. Principal component analysis was applied to identify the buildings with significant impact on district load management. Using this method, the spatial-temporal characteristics of electric loads caused by heating in one university campus in China were analyzed. The results showed that building type and the operation modes had great effects on the level and volatility of the district electric load caused by heating. Buildings with high load levels and strong coupling with the peak district electric load, such as academic buildings, often had a major impact on the power demand of the district. Therefore, they were considered as key targets for energy-saving renovation and operation optimization. Buildings with large load fluctuation, such as teaching buildings, could contribute to the peak load shaving by adjusting the heating systems’ operation.〈/p〉〈/div〉

This paper tried to answer the question: if and under what conditions, the widely-adopted 2-D CFD simulations on street canyon ventilation can represent a 3-D scenarios? 3-D simulations on street canyons with various street lengths and corresponding 2-D simulations are carried out with RNG 〈em〉k〈/em〉-〈em〉ε〈/em〉 model. Our study identified two important ventilation mechanism for controlling ventilation and dispersion in a 3-D street canyon, i.e., canyon vortex on the canyon top and the corner vortices at the street ends. The relative importance of these two driving forces will change with the street length/street width ratio (〈em〉B/W〈/em〉). For isolated street canyon, when 〈em〉B/W〈/em〉 is higher than 20 (for 〈em〉H/W〈/em〉 = 1) and 70 (〈em〉H/W〈/em〉 = 2), the street canyon ventilation will be dominated by canyon vortex, and 3-D street canyon ventilation could be simplified as a 2-D case. For multiple street canyon, the threshold of 〈em〉B/W〈/em〉 will become 20 when 〈em〉H/W〈/em〉 = 1, and 50 when 〈em〉H/W〈/em〉 = 2. The findings in this study could improve our approaches for simulating urban ventilation.〈/p〉〈/div〉

It may also affect households’ investments in renewable energy equipment, i.e. solar panels, heat pumps. Relatively little research has been conducted on how the decision to purchase electric vehicles affects the decision to invest in home renewable energy equipment. This paper, therefore, aims to examine the effects of mobility tools decisions on the intention to invest in solar panels and heat pumps, based on the data collected through a stated choice experiment. A mixed logit model is estimated to capture unobserved heterogeneity among individuals. Results show that mobility tools significantly influence the choice of home renewable energy equipment. Households who prefer to purchase electric vehicles have a higher probability to invest in solar panels and heat pumps than households who prefer other mobility tools. In addition, EV adopters’ intention to invest in solar panels are stronger than the intention to invest in heat pumps. This suggests that electric vehicle users are likely the early adopters of solar panels.〈/p〉〈/div〉

In the context of urban mobility, bicycle sharing systems deserve special mention due to the impact and growth worldwide. The dissemination and success of these systems are also linked to aspects related to quality in their provision. Thus, this paper aims to conduct a study in the context of bicycle sharing to help managers to stimulate the use of this service and contribute to the development of sustainable cities. The SERVPERF tool was adapted and used to assess the quality of bicycle sharing service, in addition to identify which aspects impact on users’ satisfaction. This approach is innovative since there is a gap in the literature about customer satisfaction analyzes and aspects related to the quality of bicycle sharing service. In this way, this study can contribute to the dissemination of this service and to the solution of urban mobility problems by identifying the aspects considered as most important for the customers and thus improving these aspects. Therefore, the bicycle sharing system may have the increasingly use and will help to reduce urban mobility problems.〈/p〉〈/div〉

In addition, we argue that this effect will be moderated by alternate non-market firm strategies, such as bribery. Using a dataset of more than 9000 firms in 30 emerging economies from Eastern Europe and Central Asia we find that political connections increase the probability of radical innovation but have no significant impact on incremental innovation. Moreover, larger bribing reduces the positive impact of political connections on radical innovation. Our results confirm the importance of political connections for firm activities, but also caution firms on their heterogeneous impact on various types of innovations, and their detrimental interplay with other non-market strategies.〈/p〉〈/div〉 〈/div〉

Srivastava, Andrew McDonald〈/p〉 〈div xml:lang="en"〉 〈h5〉Abstract〈/h5〉 〈div〉〈p〉Sustainable intensification (SI) approaches to agricultural development are urgently needed to meet the growing demand for crop staples while protecting ecosystem services and environmental quality. However, SI initiatives have been criticized for neglecting social welfare outcomes. A recent review found that better-off farmers benefitted disproportionately from SI and highlighted the dearth of studies assessing the equity of outcomes. In this study, we explore the social inclusiveness of zero-tillage (ZT) wheat adoption in Bihar, India. ZT is a proven SI technology for enhancing wheat productivity while boosting profitability and reducing greenhouse gas emissions from agricultural machinery in the densely populated Indo-Gangetic Plains. With an average landholding size of 0.39 ha, most farmers in Bihar depend on custom-hiring services to access the technology. While service provision models should foster inclusive growth by reducing financial barriers to technology adoption, early evidence suggested that smallholders remained at a disadvantage. Building on this previous research, we use a panel dataset from 961 wheat-growing households that spans a six-year period to analyze ZT adoption dynamics over time while accounting for the role of social networks and access to service provision. Using a heckprobit approach to correct for non-exposure bias, we compare determinants of ZT awareness and use in 2012 and 2015. We apply a multinomial logit model to identify determinants of early adoption, recent adoption, non-adoption, and dis-adoption. Furthermore, we explore the quality of ZT services as an additional dimension of socially-inclusive technology access. We find that the strong initial scale bias in ZT use declined substantially as awareness of the technology increased and the service economy expanded. Land fragmentation replaced total landholding size as a significant adoption determinant, which also affected the quality of ZT services received. Hence, farmers with small but contiguous landholdings appear to have gained a significant degree of access over time. We conclude that early-stage assessments of SI may be misleading, and that private sector-based service provision can contribute to socially inclusive development outcomes as markets mature.〈/p〉〈/div〉 〈/div〉

We conduct a lab experiment in the field with South African coal miners from various ethnic groups and with different trade union membership status. Our analysis suggests that union identity and ethnic identity are two social constructs that operate in a distinct and opposite fashion. Unionization acts as a factor of workers solidarity beyond the confine of union membership. Conversely, ethnicity operates as the linchpin through which discrimination among workers is infused not only between ethnic majority and minorities, but also within the majority group itself. We find that the widespread practice of subcontracting in the mining sector exacerbates ethnic discrimination among workers both between and within ethnic groupings.〈/p〉〈/div〉 〈/div〉

Nevertheless, the periodic release of certain summary statistics of the income distribution has become increasingly common. Hence, grouped data in form of income shares have been conventionally used to construct inequality trends based on lower bound approximations of inequality measures. This approach introduces two potential sources of measurement error: first, these estimates are constructed under the assumption of equality of incomes within income shares; second, the highest income earners are not included in the household surveys from which grouped data is obtained. In this paper, we propose to deploy a flexible parametric model, which addresses these two issues in order to obtain a reliable representation of the income distribution and accurate estimates of inequality measures. This methodology is used to estimate the recent evolution of global interpersonal inequality from 1990 to 2015 and to examine the effect of survey under-coverage of top incomes on the level and direction of global inequality. Overall, we find that item non-response at the top of the distribution substantially biases global inequality estimates, but, more importantly, it might also affect the direction of the trends.〈/p〉〈/div〉 〈/div〉

We argue this trickery complicates notions of social capital in community-based natural resource management, which emphasize communitarianism in the form of trust. Trust, defined as a mutual dependability often rooted in honesty, reliable information, or shared expectations, has long been recognized as essential to common pool resource management. Despite this, research that takes a critical approach to social capital places attention on the activities that foster social networks and their norms by arguing that social capital is a process. A critical approach illuminates San Evaristeño practices of lying and joking across social settings and contextualizes these practices within cultural values of harmony. As San Evaristeños assert somewhat paradoxically, for them “lies build trust.” Importantly, a critical approach to this case study forces consideration of gender, an overlooked topic in social capital research. San Evaristeña women are excluded from the verbal jousting through which men maintain ties supporting their primacy in fishery management. Both men’s joke-telling and San Evaristeños’ aversion to conflict have implications for conservation outcomes. As a result, we use these findings to help explain local resistance to outsiders and external management strategies including land trusts, fishing cooperatives, and marine protected areas.〈/p〉〈/div〉 〈/div〉

In this study, international and domestic stakeholder inputs on the future role of smart ICT in advancing Australia's infrastructure development and operations were crowdsourced for analysis. The study identifies several forms of smart ICT (e.g. building information modelling software) enabled infrastructure that possesses potential to deliver over A$9 billion per annum in domestic economic improvements, with commensurate advancement of communities, regions and urban environments. However, to be effective these smart ICT require enablement through open and interoperable data, sound governance and policy, and government leadership and coordination using dedicated resources. While smart infrastructure development is presently slow and lumbering, the identified smart ICT present as valuable strategic technologies for change and development in domestic communities.〈/p〉〈/div〉 〈/div〉

In this paper, we investigate the importance of Big Data in modern life and economy, and discuss challenges arising from Big Data utilization. Different computational intelligence techniques have been considered as tools for Big Data analytics. We also explore the powerful combination of Big Data and Computational Intelligence (CI) and identify a number of areas, where novel applications in real world smart city problems can be developed by utilizing these powerful tools and techniques. We present a case study for intelligent transportation in the context of a smart city, and a novel data modelling methodology based on a biologically inspired universal generative modelling approach called Hierarchical Spatial-Temporal State Machine (HSTSM). We further discuss various implications of policy, protection, valuation and commercialization related to Big Data, its applications and deployment.〈/p〉〈/div〉 〈/div〉

Description: 〈p〉Publication date: Available online 12 April 2018〈/p〉 〈p〉〈b〉Source:〈/b〉 Technological Forecasting and Social Change〈/p〉 〈p〉Author(s): F.W. Geels, A. McMeekin, B. Pfluger〈/p〉 〈div xml:lang="en"〉 〈h5〉Abstract〈/h5〉 〈div〉〈p〉Social acceptance and political feasibility are important issues in low-carbon transitions. Since computer models struggle to address these issues, the paper advances socio-technical scenarios as a novel methodological tool. Contributing to recent dialogue approaches, we develop an eight-step methodological procedure that produces socio-technical scenarios through various interactions between the multi-level perspective and computer models. As a specific contribution, we propose ‘transition bottlenecks’ as a methodological aid to mediate dialogue between qualitative MLP-based analysis of 〈em〉contemporary〈/em〉 dynamics and quantitative, model-generated 〈em〉future〈/em〉 pathways. The transition bottlenecks also guide the articulation of socio-technical storylines that suggest how the social acceptance and political feasibility of particular low-carbon innovations can be improved through social interactions and endogenous changes in discourses, preferences, support coalitions and policies. Drawing on results from the 3-year PATHWAYS project, we demonstrate these contributions for the UK electricity system, developing two low-carbon transition pathways to 2050 commensurate with the 2 °C target, one based on technological substitution (enacted by incumbent actors), and one based on broader system transformation (enacted by new entrants).〈/p〉〈/div〉 〈/div〉
