Biofuel Crop Sustainability

Biofuel Crop Sustainability brings together the basic principles of agricultural sustainability and special stipulations for biofuels, from the economic and ecological opportunities and challenges of sustainable biofuel crop production to the unique characteristics of particular crops which make them ideal for biofuel applications. This book will be a valuable resource for researchers and professionals involved in biofuels development and production as well as agriculture industry personnel. Chapters focus the broad principles of resource management for ecological, environmental and societal welfare, the sustainability issues pertaining to several broad categories of biofuel crops , as well as the economics and profitability of biofuels on both a local and international scale. Coverage includes topics such as utilizing waste water for field crop irrigation and algae production, reliability of feedstock supply, marginal lands, and identifying crops with traits of significance for survival and growth on low fertility soils. The development of production practices with low external inputs of fertilizer, irrigation, and pesticides is also covered. Biofuel Crop Sustainability will be a valuable, up-to-date reference for all those involved in the rapidly expanding biofuels industry and sustainable agriculture research fields.

Providing comprehensive coverage on biofuel crop production and the technological, environmental and resource issues associated with a sustainable biofuel industry, this book is ideal for researchers and industry personnel. Beginning with an introduction to biofuels and the challenges they face, the book then includes detailed coverage on crops of current importance or with high future prospects, including sections on algae, sugar crops and grass, oil and forestry species. The chapters focus on the genetics, breeding, cultivation, harvesting and handling of each crop.

With oil resources approaching their limits, biofuels have become increasingly attractive. This book provides a detailed description of the ecological implications of second and third generation biofuel feedstock production systems, beginning with an introduction to the importance of ecological sustainability alongside economic viability. The book is divided into sections describing theoretical foundation and benefits of various biofuel cropping systems, and providing a description of practical ecological limitations to achieve those fundamental benefits. The book covers such critical issues as greenhouse gas emissions, carbon balance, water cycle components, other biogeochemical and socioeconomic interactions alongside life cycle analysis principals for achieving sustainability. These are some of the most important sustainability, environmental and economic issues which biofuel industry and scientific community is seeking answers to.

The growing of crops for bioenergy has been subject to much recent criticism, as taking away land which could be used for food production or biodiversity conservation. This book challenges some commonly-held ideas about biofuels, bioenergy and energy cropping, particularly that energy crops pose an inherent threat to ecosystems, which must be mitigated. The book recognises that certain energy crops (e.g. oil palm for biodiesel) have generated sustainability concerns, but also asks the question "is there a better way?" of using energy crops to strategically enhance ecosystem functions. It draws on numerous case studies, including where energy crops have had negative outcomes as well as well as cases where energy crops have produced benefits for ecosystem health, such as soil and water protection from the cropping of willow and poplar in Europe and the use of mallee eucalypts to fight salinity in Western Australia. While exploring this central argument, the volume also provides a systematic overview of the socio-economic sustainability issues surrounding bioenergy.

The originality of this book is to review and characterize the current body of scientific publications that describe the complete causal sequence from reorganization of agricultural production to land use changes (LUC) and the resulting environmental impacts. The chapters examine both the range of territorial reorganizations leading to LUC and the range of associated environmental impacts considered in the literature, including GHG emissions, atmospheric pollution, biodiversity impacts, water resources, and soil quality.

The world is on the verge of an unprecedented increase in the production and use of biofuels for transport. The combination of rising oil prices, issues of security, climate instability and pollution, deepening poverty in rural and agricultural areas, and a host of improved technologies, is propelling governments to enact powerful incentives for the use of these fuels, which is in turn sparking investment. Biofuels for Transport is a unique and comprehensive assessment of the opportunities and risks of the large-scale production of biofuels. The book demystifies complex questions and concerns, such as thefood v. fuel debate. Global in scope, it is further informed by five country studies from Brazil, China, Germany, India and Tanzania. The authors conclude that biofuels will play a significant role in our energy future, but warn that the large-scale use of biofuels carries risks that require focused and immediate policy initiatives. Published in association with BMELV, FNR and GTZ.

Biofuels global emergence in the last two decades is met with increased concerns over climate change and sustainable development. This report addresses the core issue of biofuel sustainability of biofuels and related feedstocks, drawing from a wide range of sustainability related studies, reports, policy initiatives. The report critically examines the economic, environmental and social sustainability dimensions of biofuels and review the major certification initiatives, schemes and regulations. In doing so, the report relies on extensive review of a number of country case studies covering a broad range of current biofuel-feedstocks systems. The report analysis clearly distinguish feedstock efficiency (in terms of biofuel yields per unit of land) from sustainability, especially under limiting resource (irrigated water) or sensitive areas (carbon stocks). Also, long run economic viability depend on the future policy support, technical innovations in biofuel systems, economics of biofuel supply and demand and trade-offs between food and energy uses as well as feedstock productivity gains. Biofuels can present both advantages and risks for environmental sustainability; the latter being often difficult to measure or monitor and may conflict with economic sustainability unless great strides in productivity gains are achieved. Social sustainability is the weakest link in current biofuel certification schemes owing to intrinsic local factors and as efforts target more few negative social impacts; much less focus is placed on inclusive processes that strengthen marginal stockholders participation and benefits. Biofuel certification schemes need to be more smallholder inclusive, perhaps through policy initiatives. Finally, poor developing countries, especially with abundant land and biomass production potential, need to prioritise food security and poverty reduction. In many cases, biofuel models that encourage small scale integrated bioenergy systems may offer higher rural development impacts. FDI-induced larger-scale biofuel projects, on the other hand, may be suitable in those situations where countries have sufficient industrial capacity, besides land and biomass potential, and when these biofuel projects can be fully integrated into domestic energy strategies that do not conflict with food production potential and food security.

This report was produced by the Working Group on biofuels of the International Panel for Sustainable Resource Managemet. It provides an overview of the key problems and perspectives toward sustainable production and use of biofuels. It is based on an extensive literature study, taking into account recent major reviews. The focus is on so-called first generation biofuels while considering further lines of development. In the overall context of enhancing resource productivity, options for more efficient and sustainable production and use of biomass are examined. In particular, "modern biomass use" for energetic purposes, such as biomass used for (co-)generation of heat and power and liquid biofuels for transport, are addressed and related to the use of biomass for food and material purposes. Whereas improving the efficiency of biomass production plays a certain role towards enhancing sustainability, progress will ultimately depend on a more efficient use of biotic (and abiotic) resources (incl. for instance an increased fuel economy of car fleets), although a full consideration of all relevant strategies towards this end (e.g changing diets high in animal based foods and reducing food losses) is beyond the scope of this report.
