The publication was prepared based on information provided by 86 countries, outcomes from regional and subregional consultations and commissioned thematic studies. It includes: •an overview of definitions and concepts related to Forest Genetic Resources (FGR) and a review of their value; •a description of the main drivers of changes; •the presentation of key emerging technologies; •an analysis of the current status of FGR conservation, use and related developments; •recommendations addressing the challenges and needs.

Recent history reveals that both the large-scale reforestation projects of the 20th century have often been less successful than anticipated, and that tree growing by smallholders – as an alternative means to combat deforestation and promote sustainable land use – has received relatively little attention from the scientific and development communities. Taking a first step to addressing that balance, this collection of peer-reviewed papers adopts a comparative approach to explore the potential role that tree growing by farmers can play in sustainable forest management. The goal of this approach is to identify common threads and to start to develop a framework for future research and practice. Presenting case studies from the Philippines and comparative data from a number of Asian countries the book reveals that farmer tree growing has the potential to play a significant role in sustainable forest management, and discusses the surrounding issues which must be addressed in order to realise this potential. The book is primarily aimed at research scientists and graduate students interested in relevant aspects of forestry, agroforestry, agricultural diversity, natural resource management and conservation in agricultural landscapes, as well as those involved in sustainable development and international development studies. It will also provide a valuable reference for professionals, managers, consultants, policy makers and planners dealing with issues in sustainable development, natural resource management, land use change issues and participatory approaches to resource management.
Tree based production systems abound especially in the tropics. Despite the pervasiveness of such multipurpose “trees-outside-forest” resources, they have not attracted adequate attention in the development paradigms of many nation states. These multispecies production systems impact the ecosystem processes favourably. Yet, our understanding of the diversity attributes and carbon dynamics under agroforestry is not adequate. This book focuses on the role of multispecies production systems involving tree and crop species as a means for carbon sequestration and thereby reduce atmospheric carbon dioxide levels. Sixteen chapters organized into three broad sections titled: Measurement and Estimation, Agrobiodiversity and Tree Management, and Policy and Socioeconomic Aspects represent a cross section of the opportunities and challenges in current research and emerging issues in harnessing carbon sequestration potential of agroforestry systems.
"In addition to assessing existing conditions and knowledge, the IAASTD uses a simple set of model projections to look at the future, based on knowledge from past events and existing trends such as population growth, rural/urban food and poverty dynamics, loss of agricultural land, water availability, and climate change effects. This set of volumes comprises the findings of the IAASTD. It consists of a Global Report, a brief Synthesis Report, and 5 subglobal reports. Taken as a whole, the IAASTD reports are an indispensable reference for anyone working in the field of agriculture and rural development, whether at the level of basic research, policy, or practice."--BOOK JACKET.
