Book Description
Greenhouse Gases Balance of Bioenergy Systems covers every stage of a bioenergy system, from establishment to energy delivery, presenting a comprehensive, multidisciplinary overview of all the relevant issues and environmental risks. It also provides an understanding of how these can be practically managed to deliver sustainable greenhouse gas reductions. Its expert chapter authors present readers to the methods used to determine the greenhouse gas balance of bioenergy systems, the data required and the significance of the results obtained. It also provides in-depth discussion of key issues and uncertainties, such as soil, agriculture, forestry, fuel conversion and emissions formation. Finally, international case studies examine typical GHG reduction levels for different systems and highlight best practices for bioenergy GHG mitigation. For bringing together into one volume information from several different fields that was up until now scattered throughout many different sources, this book is ideal for researchers, graduate students and professionals coming into the bioenergy field, no matter their previous background. It will be particularly useful for bioenergy researchers seeking to calculate greenhouse gas balances for systems they are studying. I will also be an important resource for policy makers and energy analysts. - Uses a multidisciplinary approach to synthesize the diverse information that is required to competently execute GHG balances for bioenergy systems - Presents an in-depth understanding of the science underpinning key issues and uncertainty in GHG assessments of bioenergy systems - Includes case studies that examine ways to maximize the GHG reductions delivered by different bioenergy systems

Book Description
This book brings together information on the contrasting characteristics, condition, present use and problems of the world's main natural grasslands. Since grassland is commercialized through the grazing animal, particular attention is paid to the livestock production systems associated with each main type. Grazing resources are more than simply edible herbage: many other factors have to be taken into account, notably water in all areas, and shelter in winter-cold climates. Seasonality of forage supply is a characteristic of almost all grazing lands, so the strategies for dealing with lean seasons are described. The main problems of each type are mentioned and possible strategies for their sustainable management discussed - taking into account their multiple functions, not only livestock production. The book is primarily aimed at agricultural scientists, educationalists, extensionists and decision-makers with interests in responsible use of extensive grasslands.

Book Description
Although bioenergy is a renewable energy source, it is not without impact on the environment. Both the cultivation of crops specifically for use as biofuels and the use of agricultural byproducts to generate energy changes the landscape, affects ecosystems, and impacts the climate. Bioenergy and Land Use Change focuses on regional and global assessments of land use change related to bioenergy and the environmental impacts. This interdisciplinary volume provides both high level reviews and in-depth analyses on specific topics. Volume highlights include: Land use change concepts, economics, and modeling Relationships between bioenergy and land use change Impacts on soil carbon, soil health, water quality, and the hydrologic cycle Impacts on natural capital and ecosystem services Effects of bioenergy on direct and indirect greenhouse gas emissions Biogeochemical and biogeophysical climate regulation Uncertainties and challenges associated with land use change quantification and environmental impact assessments Bioenergy and Land Use Change is a valuable resource for professionals, researchers, and graduate students from a wide variety of fields including energy, economics, ecology, geography, agricultural science, geoscience, and environmental science.

Book Description
The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.

Book Description
This paper demonstrates the contribution of the forestry sector to national economies at the global, regional and country levels. It presents the status and trends of the forestry sector's contribution (total employment, value-added and export earnings) and analyses the driving forces behind these trends. The study gives a reasonable estimation of the general trends in the sector at the regional and global level, with some estimations at the level of individual countries. This is the second update of FAO's original report on the topic.

Book Description
The trade of global bioenergy commodities, such as ethanol, biodiesel and wood pellets has been growing exponentially in the past decade, and have by 2013 reached true “commodity” volumes, i.e. tens of millions of tonnes traded each year, and billions (both in US$/€) of annual turnover. IEA Bioenergy Task 40 was founded in 2004 and is now in its 4th triennium. For the past 9 years, task 40 has monitored the developments in international bioenergy trade, including the organization of about 20 workshops on trade-related topics, and the publication of over 100 studies, country reports, newsletters, etc. The amount of material produced over the years and insights gained in how biomass markets and international trade of biomass and biofuels has developed is impressive. Besides that the group has produced overviews and insights, also a large amount of practical experience has been brought together in what works and what doesn’t. Last but not least, based on all this, there are clear(er) views on how to proceed to build working sustainable international biomass markets in the future. This book compiles those lessons and insights into an easily accessible book publication.

Book Description
To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Book Description
Over the past decade, the Brazilian government has actively promoted oil palm in the Amazon biome as an alternative biodiesel feedstock to soy. Because of oil palms comparatively high productivity, it places less demand on land than soy and could thereby contribute to reducing pressure on the Amazonian forest. Although oil palm has long been a leading driver of deforestation and social conflict in major producer countries in Southeast Asia, the Brazilian government has put in place a number of mechanisms to ensure oil palm is cultivated sustainably and the sector is inclusive of the rural poor. Through research conducted in Brazils leading palm oil producing state of Pará, this paper analyzes the evolution and dynamics of the Brazilian palm oil value chain and the economic, environmental and social challenges faced by the sector. In so doing, it shows that under the right institutional and regulatory conditions, the palm oil sector can expand sustainably and inclusively within forested ecosystems. This though translates into considerably higher production costs for producers, thus undermining the international competitiveness of the Brazilian palm oil sector.
