Book Description
For thousands of years, forest biomass or wood has been among the main energy sources of humans around the world. Since the industrial revolution, fossil fuels have replaced wood and become the dominant source of energy. The use of fossil fuels has the disadvantage of increasing atmospheric concentrations of greenhouse gases (GHGs), especially carbon dioxide (CO2), with the consequent warming of global climate and changes in precipitation. In this context, the substitution of fossil fuels with renewable energy sources like forest biomass is among the ways to mitigate climate change. This book summarizes recent experiences on how to manage forest land to produce woody biomass for energy use and what are the potentials to mitigate climate change by substituting fossil fuels in energy production. In this context, the book addresses how management can affect the supply of energy biomass using short-rotation forestry and the conventional forestry applying long rotations. Furthermore, the book outlines the close interaction between the ecological systems and industrial systems, which controls the carbon cycle between the atmosphere and biosphere. In this context, sustainable forest management is a key to understand and control indirect carbon emissions due to the utilization of forest biomass (e.g. from management, harvesting and logistics, and ecosystem processes), which are often omitted in assessing the carbon neutrality of energy systems based on forest biomass. The focus in this book is on forests and forestry in the boreal and temperate zones, particularly in Northern Europe, where the woody biomass is widely used in the energy industry for producing energy.

Book Description
Bioenergy from Sustainable Forestry synthesizes information needed to design or implement sustainable forest management systems for production of biomass for energy in conjunction with other forest products. It is organized around the criteria for sustainable forest management: productivity, environment, social issues, economics, and legal and institutional framework. More than 25 international experts from 10 countries have brought together available ecological, physical, operational, social and economic information and identified gaps in knowledge related to biomass production and harvesting systems. This is the first time that such comprehensive information has been brought together under one cover, using an integrated, holistic approach. Guiding principles and state of the art knowledge are emphasized. The book will enable forest resource managers and planners to evaluate the ability of specific forest regions to sustainably meet bioenergy production demands.

Book Description
Within Oregon there is considerable interest in the possibility of converting woody biomass to energy. This interest stems from three converging factors: the desire to reduce the threat of uncharacteristic wildfire by removing excess material from the forests, the possibility to stimulate rural economies that are dependent on forest products, and generation of renewable and/or clean energy from a local source. There have been a number of studies to assess the feasibility of wide-scale conversion of biomass to energy. These efforts have largely focused on technical barriers to the use of biomass for energy rather than social barriers. This study explores the social context of converting forest biomass to energy, through use of semi-structured interviews. Forty interviewees were purposively selected from the following Oregon stakeholder groups: federal and state agencies, elected officials, community organizations, conservation organizations, the forest industry sector, Tribes, energy utilities and non-utility energy experts. Information gained through the interviews was used to meet two research objectives: 1) to understand stakeholders' views on converting forest biomass to energy in Oregon; 2) to identify, from the perspectives of stakeholders, the opportunities for and barriers to converting forest biomass to energy, and potential strategies to overcome the barriers. In addition, there were two secondary objectives: a) to identify areas of common ground and conflict between and within stakeholder groups; and b) to identify policy components that would be necessary in the integration of the forestry and energy industries in Oregon. Among research participants there was wide agreement on what constitutes forest biomass; typically small diameter material that is currently non-merchantable, produced as a by-product of restoration or other forest management activities. There was most agreement that restoration treatments are needed in low-elevation ponderosa pine forests in eastern and southwestern Oregon to reduce the risk of uncharacteristically large and severe wildfire. It is this risk of unusually intense wildfire that many research participants felt was driving this issue in Oregon, rather than potential energy or rural economic development benefits. Many research participants wanted at-risk forests restored to conditions within their historic/natural range of variability, which depended on site specific characteristics, but generally meant fewer trees per acre and inclusion of low-intensity fire. The top three reasons research participants were interested in biomass utilization were the opportunities to generate renewable energy, restore forests, and stimulate economic growth in rural communities. While participants were enthusiastic about these opportunities, they brought up a number of barriers that would have to be addressed before the full suite of opportunities could be realized. The most vital and most challenging barrier was access to supply. Factors making supply more difficult to secure included the expense associated with long transport distances, and that while supply needs to be long-term, continuous, inexpensive, and guaranteed, it is mostly on federal land, where the public is involved in land management decisions and politics plays a role. Another challenge is the long history of contention between parties related to forest products coming from federal land, and these parties would have to all agree that biomass utilization using supply from federal forests is acceptable before supply could be made available. Many research participants suggested that collaboration could allow these projects to be developed in a manner acceptable to all parties. Costs could be federally subsidized to make projects more feasible. Participants encouraged development of pilot projects to move discussion from speculation to actuality. Many research participants expressed more comfort in smaller energy facilities to prevent energy needs from dictating forest management, i.e., to prevent "the tail from wagging the dog." The overarching goal of this research is to provide information useful to collaboration groups, policymakers, land managers, communities, and relevant advocacy groups to create a foundation for discussions as forest biomass energy becomes an increasingly prominent issue in Oregon.

Book Description
From time immemorial, firewood has been a very important source of energy for mankind. Later in history, wood for energy decreased its importance because of other more convenient and cheaper sources, mainly fossil fuels. Today, focus is again on use of forests as a producer of energy with main drivers being climate change, shortage and increasing prices of fossil fuel sources, and safety in energy supplies. However, intensive use of forest biomass is qu- tioned since fundamental ecological processes may be influenced negatively thus making up a trade-off with the benefits of using an otherwise sustainable source of energy. In this book, selected aspects of intensive use of forest b- mass for energy is treated with main focus on ecological aspects like maintenance of soil fertility, recycling of the combustion ash, inf- ence on biodiversity and pests, and economical aspects both at forest owners level and for society. Another focus point is the implemen- tion of this knowledge into decision support, recommendations and guidelines. The geographical scope is mainly the Nordic and Baltic region. The EU-financed project “Wood for Energy, - a contribution to the development of sustainable forest Management” (WOOD-EN- 1 MAN) , make up the frame for the book. Seven partners participated in the project: Forest & Landscape Denmark, Swedish University of Agricultural Sciences, Finnish Forest Research Institute, Norwegian Forest and Landscape Institute, Lithuanian Forest Research Institute, Latvian State Forestry Research Institute, and Estonian University of Life Sciences with Forest & Landscape Denmark as coordinator.

Book Description
Interest in biomass energy resources from forests, farms and other sources has been rapidly increasing in recent years because of growing concern with reducing carbon dioxide emissions and developing alternatives to increasingly scarce, expensive and insecure oil supplies. The uniqueness of this book is its coverage of biomass energy markets in the US from an economic as well as technical perspective. Existing books typically focus on single markets or technical aspects at the exclusion of economics, and have given greater coverage to biomass energy outside the US. This edited collection has three main parts. Part One provides a historical overview of forest biomass energy use in the US; the major technologies, economics, market prospects, and policies. Part Two presents forest biomass energy assessments, including life cycle and sustainability perspectives, and Part Three includes five sets of regional case studies. After reviewing the history of wood energy use in the US and technology options, the book shows that forests could displace sixteen per cent of domestic transportation fuel use in 2030. Renewable Energy from Forest Resources in the United States includes a Foreword from Chris Flavin, President of the Worldwatch Institute.
