Highlights Oil quality in four rapeseed cultivars was severely impaired in a climate with simultaneous elevation of temperature, [CO2] and [O3]. The effects were unforeseeable from single factor experiments., Plant oil is an essential dietary and bio-energy resource. Despite this, the effects of climate change on plant oil quality remain to be elucidated. The present study is the first to show changes in oil quality and quantity of four rapeseed cultivars in climate scenarios with elevated [CO2], [O3] and temperature (T) combined and as single factors. The combination of environmental factors resembled IPCC’s ‘business as usual’ emission scenario predicted for late this century. Generally, the climate scenarios reduced the average amounts of the six fatty acids (FAs) analysed, though in some treatments single FAs remained unchanged or even increased. Most reduced was the FA essential for human nutrition, C18:3-ω3, which decreased by 39% and 45% in the combined scenarios with elevated [CO2]+T+[O3] and [CO2]+T, respectively. Average oil content decreased 3–17%. When [CO2] and T were elevated concurrently, the seed biomass was reduced by half, doubling the losses in FAs and oil content. This corresponded to a 58% reduction in the oil yield per hectare, and C18:3-ω3 decreased by 77%. Furthermore, the polyunsaturated FAs were significantly decreased. The results indicate undesirable consequences for production and health benefits of rapeseed oil with future climate change. The results also showed strong interactive effects of CO2, T and O3 on oil quality, demonstrating why prediction of climate effects requires experiments with combined factors and should not be based on extrapolation from single factor experiments.

Along with economic growth and improved living standards, waste from households, industries, and commercial or service establishments is expected to increase rapidly over the next years. Managing this waste is a hard challenge for the Government of Vietnam because of its substantial cost and lack of awareness and participation of people and businesses. Wastes can be classified according to: their form (wastewater, solid waste); their origin (industrial wastes, agricultural wastes, urban (municipal) wastes); and their hazardous nature (non-hazardous or hazardous).

This paper informs the national and international policy discussions related to the adoption of the United Nations Reducing Emissions from Deforestation and Forest Degradation Programme. Effective program instruments must carefully consider incentives, opportunity costs, and community interactions. A choice experiment survey was applied to rural Ethiopian communities to understand respondents’ preferences toward the institutional structure of the program contracts. The results show that respondents have particular preferences about how Reducing Emissions from Deforestation and Forest Degradation programs are structured with regard to the manner in which the payments are divided between the households and the communities, the restrictions on using grazing land, and the level of payments received for the program. Surprisingly, restrictions on firewood collection do not significantly impact contract choice. The paper further analyzes the structure of the preferences by using attribute interaction terms and socio-demographic interaction terms. The analysis finds significant regional variation in preferences, indicating that Reducing Emissions from Deforestation and Forest Degradation should be tailored to specific regions. Finally, the marginal willingness to pay for attributes is calculated using the traditional preference space approach, as well as the more recent willingness-to-pay approach.

Biologically diverse ecosystems in countries served by the World Bank provide an array of valuable economic services. While the benefits of conserving ecosystems frequently outweigh the costs, conversion of these ecosystems to other uses occurs anyway, because many ecosystem benefits are of a public good nature, without markets that would reflect their real value. The objective of this paper was defined at a Concept review meeting held on December 2009 and is to increase the understanding on how biodiversity is incorporated in a development agency such as the World Bank Group (WBG) and how the WBG can enhance its role in biodiversity and ecosystems protection and management as a key ingredient to reach development sustainability. In order to define a reasonable strategy to prepare this paper, two approaches were used: the first was to carry out background and analytical studies, and the second was to consult with a wide range of stakeholders including Bank staff, Non-Governmental Organizations (NGOs), and indigenous groups. Biodiversity provides many instrumental benefits, from food and fuel to recreation. But even where biodiversity is not immediately instrumental, it represents global public goods that must be protected, if only for their potential value in the future. The Global Environment Facility (GEF) has been the mainstay of grants implemented by the Bank ($1.4 billion) for biodiversity conservation and management, but the Bank has itself committed $2 billion in loans and has leveraged $2.9 billion in co-financing.

This internal background paper has been prepared to help inform the 2010 environment strategy with respect to a proposed way forward on use of country systems. The World Bank Group environment strategy is built on three pillars: leveraging natural resources for growth and poverty reduction; managing the environmental risks to growth and development; and transforming growth paths. As part of its exploration of these three pillars, the strategy considers the question of environmental co-benefits of climate change actions. In particular, it poses the question of potential trade-offs between actions to address climate change and other local and regional environmental priorities, and considers how to maximize co-benefits arising from climate action. The primary objective of this background paper is to assess the potential for climate change mitigation and adaptation actions to provide environmental co-benefits, particularly in the quality of environmental media, flow of ecosystem services, and maintenance of biodiversity. To accomplish this, the paper is organized in five sections: section one gives provision of an organizing framework to identify and classify potential co-benefits; section two gives summary of the external literature on co-benefits; section three gives review of examples from the World Bank portfolio; section four presents initial thoughts on creation of enabling conditions for co-benefit provision; and section five gives review of implications for the environment strategy.

The world development report 2010 estimates that an additional $200 billion per year of climate-related financing is needed in developing countries between now and 2030 to keep global average temperature rise within 2 degrees Celsius. Developing countries face increased financing challenges over coming decades as they seek to pursue economic development along a lower emission trajectory. The goal of this paper is twofold: i) to provide greater information and clarity on these three mitigation-related climate financing instruments available for the World Bank Group (WBG) and their application in the context of specific projects and national policy frameworks; and ii) to draw lessons for the broader development community on how resources from different climate financing instruments can be combined for expanded impact, increased leverage, and enhanced efficiency. This paper represents an initial contribution to this field and will be followed by papers focusing on guarantees for low-carbon growth support for the private sector and the challenges of financing climate resilience and adaptation.

Resumen Actualmente se busca nuevas opciones de energías limpias para mitigar el efecto de invernadero y lograr sistemas de producción verdaderamente sostenibles; entre éstas, la energía solar y el uso de biomasa y otras fuentes renovables se han recomendado particularmente para lograr la captura local de carbono y la adaptabilidad al cambio climático. Este artículo presenta el diseño de un sistema térmico y fotovoltaico, y los resultados preliminares obtenidos tras su instalación en lecherías y plantas procesadoras de lácteos ubicadas en la Región Huetar Norte de Costa Rica, con datos que demuestran la potencialidad de la producción energética a partir de la energía solar en actividades agropecuarias. Estos resultados preliminares han permitido comprobar que mediante estos sistemas se logra producir alrededor del 30% de la energía necesaria para estas actividades, contribuyendo de esta forma a disminuir los costos de producción, la emisión de gases de efecto invernadero y por ende, la huella de carbono. Abstract New clean energy alternatives to mitigate the greenhouse effect and achieve real clean production are currently being sought. Among these alternatives, solar energy and use of biomass and other renewable sources have been recommended for their effectiveness in adaptability to climate change and local carbon sequestration. This paper presents the design and preliminary results of a thermal system installed in a milk factory and dairy processing plants located in the North Huetar Region of Costa Rica. The generated data show the potentiality of energy production by solar energy systems in agricultural activities. These preliminary results have shown that these systems make it possible to produce about 30% of the energy needed for these activities, thereby allowing reduce production costs, emission of greenhouse gases and, consequently, carbon footprint.

This paper conducts an integrated assessment of climate change impacts and climate mitigation on agricultural commodity markets and food availability in low- and middle-income countries. The analysis uses the partial equilibrium model GLOBIOM to generate scenarios to 2080. The findings show that climate change effects on the agricultural sector will increase progressively over the century. By 2030, the impact of climate change on food consumption is moderate but already twice as large in a world with high inequalities than in a more equal world. In the long run, impacts could be much stronger, with global average calorie losses of 6 percent by 2050 and 14 percent by 2080. A mitigation policy to stabilize climate below 2°C uniformly applied to all regions as a carbon tax would also result in a 6 percent reduction in food availability by 2050 and 12 percent reduction by 2080 compared to the reference scenario. To avoid more severe impacts of climate change mitigation on development than climate change itself, revenue from carbon pricing policies will need to be redistributed appropriately. Overall, the projected effects of climate change and mitigation on agricultural markets raise important issues for food security in the long run, but remain more limited in the medium term horizon of 2030. Thus, there are opportunities for low- and middle-income countries to pursue immediate development needs and thus prepare for later periods when adaptation needs and mitigation efforts will become the greatest.

This paper estimate the effects of collective action in Nepal’s community forests on four ecological measures of forest quality. Forest user group collective action is identified through membership in the Nepal Community Forestry Programme, pending membership in the program, and existence of a forest user group whose leaders can identify the year the group was formed. This last, broad category is important, because many community forest user groups outside the program show significant evidence of important collective action. The study finds that presumed open access forests have only 21 to 57 percent of the carbon of forests governed under collective action. In several models, program forests sequester more carbon than communities outside the program. This implies that paying new program groups for carbon sequestration credits under the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Degradation in Developing may be especially appropriate. However, marginal carbon sequestration effects of program participation are smaller and less consistent than those from two broader measures of collective action. The main finding is that within the existing institutional environment, collective action broadly defined has very important, positive, and large effects on carbon stocks and, in some models, on other aspects of forest quality.

Nearly half the world's population and about 81 percent of Sub-Saharan African (SSA) households rely on wood-based biomass energy (fuel wood and charcoal) for cooking. This degree of reliance is far greater than in any other region. While the use of biomass fuels in China, India and much of the developing world has peaked or will do so in the near future, SSA's consumption will either remain at very high levels or even grow over the next few decades. Population growth, coupled with strong urbanization dynamics and relative price changes of alternative fuels, offset the important achievements made over the past decade by significant investments in energy access, rural and urban electrification, off-grid energy developments, and the promotion of alternative energy sources. With increasing economic development, the demand for energy is increasing as well and consumers depend on a broader portfolio of energy sources to satisfy growing energy needs. While electricity and other energy sources are needed to satisfy additional energy needs emerging with economic development, a vast majority of Sub-Saharan African consumers continue to use wood based biomass energy for cooking. Especially electricity is not regarded a suitable alternative for cooking given equipment and use costs. Biomass burning in cook stoves also emits black carbon (BC) as part of visible smoke, which is particulate matter that results from incomplete combustion. Climate science now views BC as the second or third largest warming agent after carbon dioxide, alongside methane. In the case of biomass cooking, the warming effects of BC and the cooling effects of organic carbon that is also emitted during the burning appear to be closely balanced. Given the present uncertainty about the net impact, additional research is currently underway. Black carbon has also an impact at the regional level: it accelerates melting of ice and snow, and contributes to regional pollution which can alter climatic conditions and precipitation patterns over a wide area. This paper advocates that any policy reform should entail a combination of clear rules, transparent enforcement, strong incentives and awareness-creation/capacity development. Key stakeholders and the general public need guidance by way of information campaigns, training, and demonstration projects to ensure that awareness-deficits or false perceptions do not curtail policy implementation. The bureaucratic and administrative barriers e.g. overcomplicated forest management planning requirements, complex fiscal systems and land tenure procedures may inhibit development and thus warrant critical reflection. The regulatory framework needs to integrate externalities in order to promote adequate pricing of charcoal, and thus enhance regional economies.
