Because of the major opportunities and risks associated with it, and the complexity of the subject, bioenergy policy has in a short time become a challenging political task for regulators and planners – a task that can only be accomplished through worldwide cooperation and the creation of an international framework. This book's central message is that the sustainable potential of bioenergy, which can be tapped all over the world, should be utilized – provided that threats to sustainability are avoided. In particular, the use of bioenergy must not endanger food security or the goals of nature conservation and climate change mitigation.

The North American Great Plains is a major global breadbasket but its agriculture is stressed by drought, heat, damaging winds, soil erosion and declining ground water resources. Biomass production and processing on the Plains would partially restore a perennial vegetative cover and create employment opportunities. This book explores the possibility that the ecology and economy of the Plains region, and similar regions, would benefit from the introduction of perennial biomass crops.

This book provides a holistic framework for assessing the environmental and economic impacts of land-use strategies for a range of purposes, such as food, animal feed, biomass and biofuels, and timber. Using land for one purpose negates its use for any other competing purpose. Given that it is in limited supply, land needs to be optimised so that it can meet the increasing demand for crops of a growing and wealthier human population, while providing ecosystem services, such as carbon storage (i.e. climate-change mitigation). The framework is quantitative and includes various indirect effects, like indirect land-use change, and is a robust basis with which to assess global impacts from land-use decisions on climate change, ecosystem services and biodiversity.

This completely revised second edition includes new information on biomass in relation to climate change, new coverage of vital issues including the "food versus fuel" debate, and essential new information on "second generation" fuels and advances in conversion techniques. The book begins with a guide to biomass accumulation, harvesting, transportation and storage, as well as conversion technologies for biofuels. This is followed by an examination of the environmental impact and economic and social dimensions, including prospects for renewable energy. The book then goes on to cover all the main potential energy crops.

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.
