Book Description
Biofuels and food are dependent on the same resources for production: land, water, and energy. The conjuncture of food, energy, and climate crises demands a new direction in how to harness agriculture to the joint tasks of energy-saving, emissions reduction, and food security. Global Economic and Environmental Aspects of Biofuels focuses on the all-important question of the efficacy of biofuels as a solution to the global energy problem. Written by a distinguished team from five countries and multiple disciplines including agronomy, petroleum engineering, ecology, and meteorology, the book addresses the use of biofuels produced from crops and various organic materials as alternatives or supplements to petroleum. Key Features Discusses biofuels within the context of the world population problem, food, malnutrition, resource depletion, and climate change Asks the critical question whether the production of ethanol from corn, sugar cane, crop residues, and other organic materials has proven too costly in both economic and environmental terms Analyzes the uses and interdependencies among land, water, and fossil energy resources in food versus biofuel production Includes case studies on the economic and environmental impacts of biofuel production and use from the United States, Europe, Brazil, and tropical environments Explores the future production of biodiesel and ethanol from salt-water algae and tropical palms, while recognizing the technological problems that must be resolved in processing these materials This book examines key environmental and economic issues associated with the production of ethanol as a fuel, from corn, sugar cane, crop residues, and other organic materials. It brings together the opinions of a number of U.S. scientists and experts from Spain, Italy, the United Kingdom, and Brazil, and highlights the remarkable agreement among the contributors on the pros and cons of biofuels as an answer to future petroleum shortages. This mix of contributors and opinions presents a well-rounded view of the subject that puts a spotlight on unresolved concerns and complexities that are often overlooked.

Book Description
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.

Book Description
Around the world, many countries are increasing efforts to promote biomass production for industrial uses including biofuels and bio-products such as chemicals and bio-plastic. Against a backdrop of lively public debate on sustainability, bioenergy wields both positive and negative impacts upon a variety of environmental and socio-economic issues. These include property rights, labor conditions, social welfare, economic wealth, poverty reduction and more. This book discusses the issues and impacts of bioenergy, taking into account the local and regional framework under which bioenergy is produced, touching upon educational level, cultural aspects, the history and economies of the producing countries and an array of policies including environmental and social targets. The book surveys and analyzes global bioenergy production from a number of perspectives. The authors illustrate the complexity of interrelated topics in the bioenergy value chain, ranging from agriculture to conversion processes, as well as from social implications to environmental effects. It goes on to offer insight on future challenges associated with the expected boom of a global bio-based economy, which contributes to the paradigm shift from a fossil-based to a biomass and renewable energy-based economy. The expert contributors include researchers, investors, policy makers, representatives from NGOs and other stakeholders, from Europe, Africa, Asia and Latin America. Their contributions build upon the results of the Global-Bio-Pact project on “Global Assessment of Biomass and Bio-product Impacts on Socio-economics and Sustainability,” which was supported by the European Commission in its 7th Framework Program for Research and Technological Development, conducted from February 2010 to January 2013. The book benefits policy makers, scientists and NGO staffers working in the fields of agriculture, forestry, biotechnology and energy.

Book Description
A new economic opportunity for sub-Saharan Africa is looming large: biofuel production. Rapidly rising energy prices are expected to remain high for an extended period of time because of the increasing demand in prospering and populous countries such as China and India, the depletion of easily accessible supplies of crude oil, and concern over global climate change. As a result, there is renewed interest in biofuels as an alternative to fossil fuels. Africa is uniquely positioned to produce these new cash crops for both domestic use and export. The region has abundant land resources and preferential access to protected markets with higher-than-world-market prices. The rapid growth in the demand for transport fuels in Africa and high fuel prices create domestic markets for biofuels. The European Union and the United States have approved legislation that requires large increases in the consumption of biofuels over at least the next decade. Imports are expected to be needed to meet these mandates, thus opening the door to African and other developing countries that can produce biofuels or feedstocks for biofuels competitively. Expanding the production of crops for biofuels will affect the entire rural sector in Africa as resources are shifted away from traditional crops and the prices of all agricultural commodities rise. Even smallholders can participate in producing biofuel crops. To promote the sustainability and significant contribution of this enterprise, Biofuels in Africa provides guidance in formulating suitable policy regimes, which are based on protecting the rights of current land users, developing revenue-sharing schemes with local communities, safeguarding the environment and biodiversity, expanding institutional capacity, formulating new regulations and procedures, and emulating best practices from experienced countries. This volume will be of value to anyone interested in biofuels, including policy makers, development practitioners, private investors, researchers, and the general public. Now that African countries are trying to significantly increase their energy supply systems, biofuels are an attractive option using both dedicated crops and agricultural waste. This book provides guidance for them to develop a suitable policy regime for a significant contribution by biofuels. Professor Ogunlade R. Davidson, Minister of Energy and Water Resources, Sierra Leone Biofuels in Africa is a sorely needed resource for our understanding of the problems of expanding biofuels production in Africa. A high point of the book is a description of the projects that were started in several countries. A very useful book! Professor Jos Goldemberg, University of S o Paulo, Brazil As Africa most likely will play the same role for global biofuels as the Middle East does for oil, this comprehensive book on African biofuels should be compulsory reading for anyone interested in either African development or biofuels. The book captures the essence of long-term drivers and opportunities as well the complex challenges for investors and society of this huge emerging industry.

Book Description
Biofuels made from algae are gaining attention as a domestic source of renewable fuel. However, with current technologies, scaling up production of algal biofuels to meet even 5 percent of U.S. transportation fuel needs could create unsustainable demands for energy, water, and nutrient resources. Continued research and development could yield innovations to address these challenges, but determining if algal biofuel is a viable fuel alternative will involve comparing the environmental, economic and social impacts of algal biofuel production and use to those associated with petroleum-based fuels and other fuel sources. Sustainable Development of Algal Biofuels was produced at the request of the U.S. Department of Energy.

Book Description
This open access book presents a comprehensive analysis of biofuel use strategies from an interdisciplinary perspective using sustainability science. This interdisciplinary perspective (social science-natural science) means that the strategies and policy options proposed will have significant impacts on the economy and society alike. Biofuels are expected to contribute to reducing greenhouse gas emissions, revitalizing economies in agricultural communities and alleviating poverty. However, despite these anticipated benefits, international organizations such as the FAO, OECD and UN have published reports expressing concerns that biofuel promotion may lead to deforestation, water pollution and water shortages. The impacts of biofuel use are extensive, cross-sectoral and complex, and as such, comprehensive analyses are required in order to assess the extent to which biofuels can contribute to sustainable societies. Applying interdisciplinary sustainability science concepts and methodologies, the book helps to enhance the establishment of a sustainable society as well as the development of appropriate responses to a global need for urgent action on current issues related to biofuels.

Book Description
Land has long been overlooked in economics. That is now changing. A substantial part of the solution to the climate crisis may lie in growing crops for fuel and using trees for storing carbon. This book investigates the potential of these options to reduce greenhouse gas emissions, estimates the costs to the economy, and analyses the trade-offs with growing food. The first part presents new databases that are necessary to underpin policy-relevant research in the field of climate change while describing and critically assessing the underlying data, the methodologies used, and the first applications. Together, the new data and the extended models allow for a thorough and comprehensive analysis of a land use and climate policy. This book outlines key empirical and analytical issues associated with modelling land use and land use change in the context of global climate change policy. It places special emphasis on the economy-wide competition for land and other resources, especially; The implications of changes in land use for the cost of climate change mitigation, Land use change as a result of mitigation, and Feedback from changes in the global climate to land use. By offering synthesis and evaluation of a variety of different approaches to this challenging field of research, this book will serve as a key reference for future work in the economic analysis of land use and climate change policy.

Book Description
Extensive effort is being made globally to develop various biofuels as an inexhaustible and renewable energy source. Biofuels are viewed as promising alternatives to conventional fossil fuels because they have the potential to eliminate major environmental problems such as global warming and climate change created by fossil fuels. Among the still-developing biofuel technologies, biodiesel production from algae offers a good prospect for large-scale practical use, considering the fact that algae are capable of producing much more yield than other biofuels such as corn and soybean crops. Although research on algae-based biofuel is still in its developing stage, extensive work on laboratory- and pilot-scale algae-harvesting systems with promising prospects has been reported. This chapter presents a discussion of the literature review of recent advances in algal biomass harvesting. The chapter focuses on stability and separability of algae and algae-harvesting methods. Challenges and prospects of algae harvesting are also outlined. The review aims to provide useful information for future development of efficient and commercially viable algal biodiesel production.
