The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.
REDD+ is one of the leading near-term options for global climate change mitigation. More than 300 subnational REDD+ initiatives have been launched across the tropics, responding to both the call for demonstration activities in the Bali Action Plan and the market for voluntary carbon offset credits.
Written by leading international authors, this book presents a comprehensive review of forests in mountain regions, and their sustainable development. Based on a report prepared by the IUFRO Task Force in Sustainable Mountain Development, for the IUFRO Congress to be held in August 2000. The book addresses current issues and initiatives, and defines research needs. Key global issues and addressed is in general articles, while specific regional topics are described and highlighted within each chapter in shorter case studies. Case studies are drawn from all continents, examples including Mexico, Central Europe, Cameroon, Tanzania, Chile, Korea, New Zealand and many others. Contributions have been included from nearly 100 world experts, making this volume the definitive, state-of the art review of its subject.
The densely populated Bamenda Highlands of Cameroon remains one of the regions with the greatest land degradation problems in the country. Factors responsible for this include climate change, the hilly nature or topographic layout of the land, and human interference through overgrazing, destructive agricultural practices and the impact of deforestation. This detailed study of resource management and its ecological challenges in the Bamenda Highlands, stresses an important link between falling food output and soil deterioration. While most areas in this predominantly agricultural region enjoy food abundance, the inhabitants of high-density infertile, rugged mountainous areas are forced to resort to double cropping and intensified land exploitation that leave little room for soil regeneration. The population problem in relation to land degradation is infinitely more complicated than the region's sheer ability to produce enough food supply. The authors make a strong case for a delicate balance between human agency and environmental protection in this highly populated and physically challenging region where land is a precious resource and land conflicts are common.
This open access book provides a comprehensive overview of volcanic crisis research, the goal being to establish ways of successfully applying volcanology in practice and to identify areas that need to be addressed for future progress. It shows how volcano crises are managed in practice, and helps to establish best practices. Consequently the book brings together authors from all over the globe who work with volcanoes, ranging from observatory volcanologists, disaster practitioners and government officials to NGO-based and government practitioners to address three key aspects of volcanic crises. First, the book explores the unique nature of volcanic hazards, which makes them a particularly challenging threat to forecast and manage, due in part to their varying spatial and temporal characteristics. Second, it presents lessons learned on how to best manage volcanic events based on a number of crises that have shaped our understanding of volcanic hazards and crises management. Third, it discusses the diverse and wide-ranging aspects of communication involved in crises, which merge old practices and new technologies to accommodate an increasingly challenging and globalised world. The information and insights presented here are essential to tapping established knowledge, moving towards more robust volcanic crises management, and understanding how the volcanic world is perceived from a range of standpoints and contexts around the globe.
This book aims to give an overview on the present state of volcanic lake research, covering topics such as volcano monitoring, the chemistry, dynamics and degassing of acidic crater lakes, mass-energy-chemical-isotopic balance approaches, limnology and degassing of Nyos-type lakes, the impact on the human and natural environment, the eruption products and impact of crater lake breaching eruptions, numerical modeling of gas clouds and lake eruptions, thermo-hydro-mechanical and deformation modeling, CO2 fluxes from lakes, volcanic lakes observed from space, biological activity, continuous monitoring techniques, and some aspects more. We hope to offer an updated manual on volcanic lake research, providing classic research methods, and point towards a more high-tech approach of future volcanic lake research and continuous monitoring.
The substantial and growing interest in the monetary valuation of preferences for environmental improvement, and against environmental damage, has prompted a demand for case studies illustrating methodologies and applications of valuation techniques. In this book, the first of two volumes, the authors provide detailed case studies of valuation techniques that have been used in developing countries. They demonstrate that valuation works and that it can yield significant insights into policy-relevant issues regarding conservation and economic development. The authors address a whole range of environmental issues under the broad themes of water and air quality, biological diversity and forest functions. The economic approaches covered include contingent valuation, hedonic property prices, travel cost methodologies and benefits transfer. They also go on to look at the idea of extending national accounts to reflect changes in environmental assets. Examples of the varied and interesting case studies include valuing improvements to sanitation in Malaysia, the value of visits to game parks in South Africa and tropical forest values in Mexico. They highlight how valuation techniques can be applied, often with limited resources, to critical development issues. Academics and practitioners of environmental economics will draw great value from this unique and original work, as will the many multilateral and bilateral aid agencies. The book will also prove a valuable addition to graduate and undergraduate courses in environmental economics where there is a need for case material.
Drawing on case studies from Pacific Islands, Africa, Latin America and Southeast Asia, this book examines ecotourism enterprises controlled by indigenous people in tribal reserves or protected areas. It compares indigenous ecotourism in developed and developing counties and covers cultural ecotours, ecolodges, and bungalows, hunting and fishing tours, cultural attractions and other nature-based facilities or services.
