    Crop Prices, Agricultural Revenues, and the Rural Economy1 (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-11
    Description: Policy makers in the United States often justify agricultural subsidies by stressing that agriculture is the engine of the rural economy. We use the increase in crop prices in the late 2000s to estimate the marginal effect of increased agricultural revenues on local economies in the U.S. Heartland. We find that $1 more in crop revenue generated 64¢ in personal income, with most going to farm proprietors and workers (59%) or nonfarmers who own farm assets (36%). The evidence suggests a weak link between revenues and nonfarm income or employment, or on population. Cuts to agricultural subsidies are therefore likely to have little effect on the broader rural economy in regions like the Heartland.

    A Chat about Insurance: Experimental Results from Rural Bangladesh (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-11
    Description: Farmers throughout the developing world face multiple sources of uninsured risk to agricultural production and household assets. In this paper, we present results from an experimental demand-elicitation exercise in rural Bangladesh to shed light on smallholder farmers' interest in formal insurance products. We propose a suite of insurance and savings products, and we randomly vary the price of one insurance option (area-yield insurance) and the presence of one of the savings options (group savings). Consistent with economic theory, farmers buy more of the insurance products that cover the risks they primarily face. However, because farmers are subject to a variety of risks, they do not focus on only one type of insurance; instead, they evenly split their endowment between life and disability insurance and agricultural insurance. Demand for area-yield insurance falls with price; we also observe important cross-price elasticities with other insurance products. The presence of group savings does not alter demand for insurance, though group savings is found to be a particularly popular risk management tool, especially when decisions are made in groups.

    An integrated approach for sustainable design and assessment of residential building envelope: part I (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-16
    Description: The assessment of building envelope sustainability using existing building performance assessment methods is still a challenge and yet to be fully addressed. This is due to the single-dimensional nature and lack of integration of sustainable performance values. Besides, the issue of sustainability assessment in the building envelope requires considering many factors including life cycle considerations. As such, in an effort to develop an integrated approach that combines relevant sustainable development factors and life cycles, an integrated performance model (IPM) was developed. The IPM is an essential tool developed to aid the sustainable design of the residential building envelope that can reduce carbon emission and whole residential building energy consumption and ensure sustainable performance of the building envelope.

    Failure of natural ventilation strategy in a sustainable house in China (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-16
    Description: In recent years, the concept of green building is becoming popular in China. Architects and engineers have the opportunity to actually implement green building practices. This paper reveals the failure of a naturally ventilated LEED-certified townhouse development project in China mentioned in recent research. The house owners made great alterations for the purpose of decoration, which removed or minimized the effectiveness of natural ventilation elements in the original design. The research shows that the houses show ‘International Style’ because the natural ventilation design principles were not fully applied in the design and the localized natural ventilation strategies were not fully considered by means of computational simulation in the design stage. Also, the lack of communication between designers and the owners caused the removal of most natural ventilation elements of these houses during the occupancy period. The authors advocate three criteria to avoid failures of natural ventilation design: localized/ climate adaptive design, relationship among design elements and design intention awareness.

    Adaptive facade design for the daylighting performance in an office building: the investigation of an opening design strategy with cellular automata (2015)
    Oxford University Press
    Details
    Publication Date: 2015-08-16
    Description: Daylighting has an important role in sustainable architecture as it affects the energy consumption in a building. Especially for an office building, daylight helps not only to reduce the load on artificial lighting but also to promote work efficiency through promoting good human health, well-being and user comfort. The objective of this research is to develop an innovative façade design strategy that comes from the development of digital technology and dynamic daylight performance measuring methods. Thus, the various parameters are studied through the computational process of cellular automata (CA) to generate the several alternative opening patterns on the building façade. Each CA design value was tested under static and dynamic sky condition to analyze the quality and quantity of daylight and visual comfort throughout the year. The results were compared to find an optimum alternative design in terms of the daylighting design criteria, from building code, standard and design guidelines for the office building. Finally, research of an adaptive façade design strategy was concluded with the results from the above hybridization of generative and performative design methodology. This study discovers the architectural design approach from the CA and it will make not only progress in building façade esthetics, but also human comfort with building sustainability.

    The retrofitting of an old style semi-detached house for energy reduction and carbon savings under the UK climate (2015)
    Oxford University Press
    Details
    Publication Date: 2015-05-13
    Description: The impact of climatic change through greenhouse gas emission is a recognized major global crisis. Energy use in residential and commercial buildings is a major part of the total consumption in European countries and is estimated to be ~40% of the total load. Currently, the concept of building retrofit has become a top priority for the UK government in order to meet the national plans for reducing CO 2 emissions by 80% compared with 1990 levels by 2050. This study presents the simulation results for a case study of energy and CO 2 emission savings of a nineteenth century semi-detached building in the UK. The building was refurbished to high standards of energy efficiency, with four simulation scenarios developed for analysis: As-built, As-built 1965, As-reality and post-retrofit. DesignBuilder software was used to simulate the annual energy consumption and carbon emissions in all cases. In addition to this, thermal imaging and air-tightness tests were conducted and the results were used to validate the models. The post-retrofit results showed there is a significant reduction in energy consumption that exceeded 80% with carbon emissions being reduced above 70%. Economic analysis of each retrofit scenario was then undertaken, and results showed payback varied between 9 and 40 years due to the fluctuation in fuel prices and construction retrofit materials. The models indicate performance of the building post-retrofit can be significantly improved in terms of energy reduction and CO 2 emission savings. Further research is being performed to improve performance through field monitoring and installation of innovative retrofit technologies.

    High-efficiency ventilation and heating systems by means of solar air collectors for industry building refurbishment (2015)
    Oxford University Press
    Details
    Publication Date: 2015-05-13
    Description: For the purpose of energy conservation, modern buildings are becoming more and more air-tight and generally rely on a mechanical ventilation system. According to the literature, solar air heating systems can contribute in a cost-effective way to the heating and ventilation of utility buildings. Especially cost-efficient, unglazed, façade-integrated solar air collectors seem to be an attractive new market for façade renovation. To demonstrate the technical feasibility of generating heating energy on facades, a demonstration plant based on an unglazed solar air collector was installed in 2013 in the façade of a demonstration building and was intensively studied using energy metering.

    Local warming and violent conflict in North and South Sudan (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-14
    Description: Our article contributes to the emerging micro-level strand of the literature on the link between local variations in weather shocks and conflicts by focusing on a pixel-level analysis for North and South Sudan between 1997 and 2009. Temperature anomalies are found to strongly affect the risk of conflict, whereas the risk is expected to magnify in a range of 24–31% in the future under a median scenario. Our analysis also sheds light on the competition over natural resources, in particular water, as the main driver of such relationship in a region where pastoralism constitutes the dominant livelihood.

    Farmer Bargaining Power and Market Information Services (2015)
    Oxford University Press
    Details
    Publication Date: 2015-04-18
    Description: In many Sub-Saharan African countries, farmers typically have a choice between selling their products to traders who travel between villages and markets and transporting their products to the nearest market themselves. Because of communities’ remoteness and poor communications with marketplaces, farmers’ uncertainty about market prices is usually high. Traders may take advantage of farmers’ ignorance of the market price and extract a rent from them by offering very low prices for their products. In this article, we model bargaining interactions between farmers and traders meeting at the farmgate and we study how price information affects the bargain and the balance of power. We show the conditions for Market Information Services (MIS) to be profitable for farmers and examine efficiency issues associated with asymmetric information. Finally, we test the model’s prediction that information results in positive individual gain for farmers using original survey data collected in the Northern region of Ghana. Specifically, we estimate the causal effect of a mobile-based MIS program on farmers’ marketing performances and find that farmers who have benefited from the MIS program received significantly higher prices for maize and groundnuts: about 10% more for maize and 7% more for groundnuts than what they would have received had they not participated in the MIS program. These results suggest that the theoretical conditions for successful farmer use of MIS may be met in the field.
