Summarizes the current state of knowledge of the drivers of land-use change and describes the analytic methods used to estimate the impact of biofuel feedstock production on land use. The larger the impact of domestic biofuels feedstock production on commodity prices and the availability of exports, the larger the international land-use effects are likely to be. The amount of pressure placed on land internationally will depend in part on how much of the land needed for biofuel production is met through an expansion of agricultural land in the U.S. If crop yield per acre increases through more intensive management or new crop varieties, then less land is needed to grow a particular amount of that crop.

The indirect land use change (ILUC) effect of biofuels has called into question the greenhouse gas (GHG) mitigation benefit of biofuels compared with that of fossil fuels. This article reviews the various economic modeling approaches being used to assess the ILUC effect and discusses the key factors that influence estimates of its magnitude. We find that there is considerable variability in the magnitude of ILUC associated with a biofuel pathway across studies and within a study, depending on underlying model parameters. These estimates are sensitive to the scale of biofuel production, the mix of policies and biofuels considered, variations in the parametric assumptions that govern price transmission through international trade, and the ease of changes in land use at the intensive and extensive margins. We discuss the challenges in implementing policies to address ILUC.

While debate on biofuels and bioenergy generally has sparked controversy over claimed greenhouse gas emissions benefits available with a switch to biomass, these claims have generally not taken into account indirect land use changes. Carbon emissions from land that is newly planted with biocrops, after land use changes such as deforestation, are certainly real - but efforts to measure them have been presented subject to severe qualifi cations. No such qualifications accompanied the paper by Searchinger et al. published in Science in February 2008, where the claim was made that a spike of ethanol consumption in the USA up to the year 2016 would divert corn grown in the USA and lead to new plantings of grain crops around the world to make up the shortfall, resulting in land use changes covering 10.8 million hectares and leading to the release of 3.8 billion tons of greenhouse gas emissions in terms of CO2 equivalent. These emissions, the paper argued, would more than offset any savings in emissions by growing biofuels in the first place; in fact they would create a carbon debt that would take 160 years to repay. Such criticism would be devastating, if it were valid. The aim of this perspective is to probe the assumptions and models used in the Searchinger et al. paper, to evaluate their validity and plausibility, and contrast them with other approaches taken or available to be taken. It is argued that indirect land use change effects are too diffuse and subject to too many arbitrary assumptions to be useful for rule-making, and that the use of direct and controllable measures, such as building statements of origin of biofuels into the contracts that regulate the sale of such commodities, would secure better results.

In its second volume, this book aims to link the academic research with development in the real world and provide a historical and institutional background that can enrich more formal research. The first section will include an assessment of the evolution and the state of the nascent second-generation biofuel as well as a perspective on the evolution of corn ethanol and sugarcane ethanol in Brazil. It will also include a historical and institutional background on the biofuel industry in Brazil that has global lessons, and later, provide a technical overview of major analytical tools used to assess the economic, land use and greenhouse gas implications of biofuel policies at a regional and global level. Additionally, the book analyzes the various drivers for land use change both at a micro-economic level and at a macro-economic level. It presents studies that apply regional and global economic models to examine the effects of biofuel policies in the US, EU and Brazil on regional and global land use, on food and fuel prices and greenhouse gas emissions. These papers illustrate the use of partial and general equilibrium modeling approaches to simulate the effects of various biofuel policies, and includes studies showing the effects of risk aversion, time preferences and liquidity constraints on farmers decision to grow energy crops for biofuel production. By presenting the tools of lifecycle analysis for assessing the direct greenhouse gas intensity of biofuels, this handbook investigates the types of indirect or market mediated effects that can offset or strengthen these direct effects. It will include tools to assess the direct and indirect effects of biofuel production on greenhouse gas emissions in the US and Brazil, and ultimately provide a comprehensive background to understand the state of biofuel in the present and how to analyze their implication.

Indirect land use change (ILUC) emissions from biofuels are commonly estimated with sophisticated economic models of world agriculture. Because these are often complex, the JRC in collaboration with K. Overmars and the Netherlands Environmental Assessment Agency (PBL) has developed an alternative approach based on "historical" data. This approach gives simple and transparent estimates of ILUC emissions in recent years, even if the method is less rigorous in principle than estimates based on sophisticated economic models. The purpose is to understand how much crop expansion (and hence ILUC) would be attributed to 1 megajoule (MJ) biofuel if the crop had been used for that purpose. ILUC emissions calculated with this methodology are broadly in line with results from economic models (both in magnitude and in the relative ILUC impact of biofuels from different crops), showing a lower impact of cereals and sugar crops compared to vegetable oils.

Biofuels, Bioenergy and Food Security: Technology, Institutions and Policies explores the popular ‘Food versus Fuel’ debates, discussing the complex relationship between the biofuel and agricultural markets. From the importance of bioenergy in the context of climate change, to the potentially positive environmental consequences of growing second generation biofuels crops, this book provides important insights into the impact of policy, the technical implementation and the resulting impact of biofuels. The discussion of existing issues hindering the growth of the cellulosic biofuel industry and their remedies are particularly relevant for policy makers and others associated with the biofuel industry. Transferring information on bioenergy economy through the discussion of the current and emerging biofuel market, country specific case studies explain the existing biofuel policy and its consequences to both the energy and agricultural markets. Economic simulation models explain the future of the bioenergy markets. Biofuels, Bioenergy and Food Security: Technology, Institutions and Policies is an invaluable resource to the students, scientific community, policy makers, and investors in the bioenergy industry. Students will benefit from a variety of perspectives on major societal questions in context of the interaction between food security and bioenergy. Its review of existing literature on the biofuel marker, investment opportunities, and energy independence provides a broad overview to allow informed decision making regarding the industry. Provides an integrated overview of the world biofuel market by country, including a summary of the existing biofuel policies, role of investment opportunities, and rural development potential Discusses the impact of biofuels on efforts by developing countries to become more energy self-sufficient Examines the environmental consequences of biomass-based biofuel use.
