These report overviews recent developments in the consumption and production of bioenergy. It examines the main issues and possible economic implications of these developments and assesses their ...potential impact on land use and the environment, especially with respect to forests. The report examines both solid biomass and liquid biofuels, identifying opportunities and challenges at the regional and country levels. The development of bioenergy presents both opportunities and challenges for economic development and the environment. It is likely to have significant impacts on the forest sector, directly, through the use of wood for energy production, and indirectly, as a result of changes in land use. The impact of bioenergy on poverty alleviation in developing countries will depend on the opportunities for agricultural development, including income and employment generation, the potential to increase poor peoples' access to improved types of bioenergy; and the effects on energy and food prices. Five main messages emerge from this report: solid biomass will continue to be a principal source of energy; developments in bioenergy will have major implications for land use; tradeoffs, including those related to poverty, equity, and the environment, must be evaluated when choosing a bioenergy system; there is considerable potential for making greater use of forestry and timber waste as a bioenergy feedstock; and the climate benefits of bioenergy development are uncertain and highly location and feedstock specific.
Biofuels are currently in the middle of a heated academic and public policy debate. Biofuel production has increased fivefold in the past decade and is expected to further double by 2020. Most of ...this expansion will happen in developing nations. This volume is the first of its kind, providing a comprehensive overview of the biofuel debate in developing countries. The chapters are written by a multidisciplinary team of experts, exposing the key drivers and impacts of biofuel production and use. The book covers impacts as diverse as air pollution, biodiversity loss, deforestation, energy security, food security, greenhouse gas emissions, land use change, rural development, water consumption and other socioeconomic issues. Its wide focus accommodates examples from countries in Africa, America and Asia. As such, this book will become an indispensable companion to academics, practitioners and policy makers who wish to know more about biofuel issues in the developing world.
Above ground biomass has been listed by the Intergovernmental Panel on Climate Change as one of the five most prominent, visible, and dynamic terrestrial carbon pools. The increased awareness of the ...impacts of climate change has seen a burgeoning need to consistently assess carbon stocks to combat carbon sequestration. An accurate estimation of carbon stocks and an understanding of the carbon sources and sinks can aid the improvement and accuracy of carbon flux models, an important pre-requisite of climate change impact projections. Based on 15 research topics, this book demonstrates the role of remote sensing in quantifying above ground biomass (forest, grass, woodlands) across varying spatial and temporal scales. The innovative application areas of the book include algorithm development and implementation, accuracy assessment, scaling issues (local–regional–global biomass mapping), and the integration of microwaves (i.e. LiDAR), along with optical sensors, forest biomass mapping, rangeland productivity and abundance (grass biomass, density, cover), bush encroachment biomass, and seasonal and long-term biomass monitoring.
Biomass is a renewable energy source with increasing importance. The larger fraction of cost in biomass energy generation originates from the logistics operations. A major issue concerning biomass ...logistics is its storage, especially when it is characterized by seasonal availability. The biomass energy exploitation literature has rarely investigated the issue of biomass storage. Rather, researchers usually choose arbitrarily the lowest cost storage method available, ignoring the effects this choice may have on the total system efficiency. In this work, the three most frequently used biomass storage methods are analyzed and are applied to a case study to come up with tangible comparative results. Furthermore, the issue of combining multiple biomass supply chains, aiming at reducing the storage space requirements, is introduced. An application of this innovative concept is also performed for the case study examined. The most important results of the case study are that the lowest cost storage method indeed constitutes the system-wide most efficient solution, and that the multi-biomass approach is more advantageous when combined with relatively expensive storage methods. However, low cost biomass storage methods bear increased health, safety and technological risks that should always be taken into account.

Biofuels and Rural Poverty makes an original contribution to the current controversial global debate on biofuels, in particular the consequences that large-scale production of transport fuel ...substitutes can have on rural areas, principally in developing countries but also in some poor rural areas of developed countries.
Three key concerns are examined from a North-South perspective: ecological issues (related to land use and biodiversity), pro-poor policies (related to food and land security, gender and income generation) and equity of benefits within the global value chain. Can biofuels be pro-poor? Can smallholder farmers be equitably integrated in the biofuels global supply chain? Is the biofuels production chain detrimental to biodiversity?
Most other books available on biofuels take a technical approach and are aimed at addressing energy security or climate change issues. This title focuses on the socio-economic impacts on rural people's livelihoods, offering a unique perspective on the potential role of biofuels in reducing rural poverty.
