Tropical Deforestation And Climate Change

Tropical deforestation, fires and emissions: measurement and monitoring; How to reduce deforestation emissions for carbon credit: compensated reduction; Policy and legal frameworks for reducing deforestation emissions.

Tropical forests are an undervalued asset in meeting the greatest global challenges of our time—averting climate change and promoting development. Despite their importance, tropical forests and their ecosystems are being destroyed at a high and even increasing rate in most forest-rich countries. The good news is that the science, economics, and politics are aligned to support a major international effort over the next five years to reverse tropical deforestation. Why Forests? Why Now? synthesizes the latest evidence on the importance of tropical forests in a way that is accessible to anyone interested in climate change and development and to readers already familiar with the problem of deforestation. It makes the case to decisionmakers in rich countries that rewarding developing countries for protecting their forests is urgent, affordable, and achievable.

Tropical rain forest is being cleared so rapidly and on such a scale that it is a major global environmental problem, threatening the survival of half of the world's plant and animal species and contributing to global climate change through the greenhouse effect. But, despite widespread concern for over twenty years, only limited progress has been made in controlling deforestation and improving forest management in the humid tropics. In this book Alan Grainger offers afresh analysis of the causes of deforestation and presents an integrated strategy for controlling it. His strategy embraces agriculture, forestry and conservation and stresses the need for changes in government policies if land use is to be made more sustainable and the underlying causes of the problem are to be addressed. Controlling Tropical Deforestation is essential reading for policy makers, agronomists, foresters, conservationists and development professionals. To general readers and students on introductory courses at schools and universities it also offers the first concise but comprehensive overview of the causes, scale and consequences of deforestation. Alan Grainger is a lecturer in geography at the University of Leeds. He is author of The Threatening Desert: Controlling Desertification, also published by Earthscan. Originally published in 1992

Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

Efforts to mitigate climate change have focused on reducing carbon dioxide (CO2) emissions into the atmosphere. Some of these efforts center on reducing CO2 emissions from deforestation, since deforestation releases about 17% of all annual anthropogenic greenhouse gas (GHG) emissions and is seen as a relatively low-cost target for emissions reduction. Policies aimed at reducing deforestation are central points of a strategy to decrease carbon emissions, reflected in pending legislation in Congress (e.g., H.R. 2454 and S. 1733) as well as in international discussions, such as the December 2009 negotiations in Copenhagen. Forests exist at many latitudes. Many are concerned about the possible impacts of losing boreal and temperate forests, but existing data show little, if any, net deforestation, and their loss has relatively modest carbon consequences. In contrast, tropical deforestation is substantial and continuing, and releases large amounts of CO2, because of the carbon stored in the vegetation and released when tropical forests are cut down. There are many causes of tropical deforestation-commercial logging, large-scale agriculture (e.g., cattle ranching, soybean production, oil palm plantations), small-scale permanent or shifting (slash-and-burn) agriculture, fuelwood removal, and more. Often, these causes combine to exacerbate deforestation; for example, commercial logging often includes road construction, which in turn opens the forest for subsistence farmers. At times, tropical deforestation results from weak land tenure and/or weak or corrupt governance to protect the forests. Congress and international bodies are discussing various policies to reduce carbon emissions from deforestation and forest degradation (REDD). Reducing deforestation in the tropics is likely to have additional benefits as well, such as preserving biological diversity and sustaining livelihoods for the rural poor and for indigenous communities and cultures. Proposals may be adapted to address local and regional causes of deforestation. Various forestry practices can reduce the impacts of deforestation, and several market approaches are evolving to compensate landowners for preserving their forests. Many challenges remain for implementing REDD programs, particularly internationally, including monitoring REDD projects and improving developing-country capacity to ensure compliance. Existing evidence on forests and deforestation suggest the difficulties might be significant. Measuring forests is complicated, with multiple definitions, inaccessible sites, and expensive, complicated, and imperfect measurement technologies. This report provides basic information on forests and climate change. The first section discusses the linkages between forests and climate. The next three describe the characteristics of the three major forest biomes, with an overview of deforestation causes and impacts. This is followed by an overview of approaches to reducing deforestation. The final section examines issues related to forest and deforestation data.

The intent has been to create actionable, politically viable recommend. that can inform and guide the U.S. in its legislative and diplomatic negotiations on this issue.

Climate change represents one of the most alarming long-term threats to ecosystems the world over. This new collection of papers provides, for the first time, an overview of the potentially serious impact that climate change may have on tropical forests. The authors, a multi-disciplinary group of leading experts in climatology, forestry, ecology and conservation biology, present a state-of-knowledge snapshot of how tropical forests are likely to react to the changes being wrought on our planet's atmosphere and climate. Tropical forests represent extraordinary harbours for biological diversity, and yet as deforestation and degradation continue apace, they are under greater pressure from human impacts than ever before. Climate change adds yet another threat to these valuable ecosystems, and this volume demonstrates just how significant a problem this may really be. The authors identify certain types of forest, including tropical montane cloud forest that may be particularly vulnerable. They also show the strong likelihood of global warming aggravating problems in already fragmented forest areas.
