In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.
This book addresses key questions on biofuels within agrarian political economy, political sociology and political ecology. Contributions are based on fresh empirical materials from different parts of the world. The book starts with four key questions in agrarian political economy: Who owns what? Who does what? Who gets what? And what do they do with the surplus wealth? It also addresses the emergent social and political relations in the biofuel complex and, given the impacts on natural resources and sustainability, engages with questions about people-environment interactions. At the same time, the book is concerned with the politics of representation, that is, what are the discursive frames through which biofuels are promoted and/or opposed? The book analyses the institutional structures, and cultures of energy consumption on which a biofuels complex depends, and the alternative political and ecological visions emerging that call the biofuels complex into question. Across sixteen chapters presenting material from five regions across the North-South divide and focusing on fourteen countries including Brazil, Indonesia, India, USA and Germany, these topics are addressed within the following themes: global (re)configurations; agro-ecological visions; conflicts, resistances and diverse outcomes; state, capital and society relations; mobilising opposition, creating alternatives; and change and continuity. This book was published as a special issue of the Journal of Peasant Studies.
The agriculture (ag) sector is a source of greenhouse gas (GHG) emissions, which many scientists agree are contributing to observed climate change. Ag. is also a ¿sink¿ for sequestering carbon, which might offset GHG emissions by capturing and storing carbon in ag. soils. The two key types of GHG emissions associated with agricultural activities are methane and nitrous oxide. Contents of this report: (1) Ag. Sinks and Emissions: Source of Nat. Est.; Ag. Emissions; Ag. Carbon Sinks; Potential for Additional Uptake; (2) Mitigation Strategies in the Ag. Sector: Federal Programs; State Programs; (3) Congressional Action: Climate Change Proposals; 2008 Farm Bill Provisions; Related Initiatives Involving U.S. Ag.; Considerations for Congress. Illus.
