Book excerpt: In spite of the importance of the world's humid tropical forests our knowledge concerning their rates of change remains limited (IPCC, 2000). The second phase of a research programme (TREES-II) exploiting the global imaging capabilities of Earth observing satellites has just been completed to provide the latest information on the status of these forests. The results of the TREES II programme show that in 1990 (the Kyoto Protocol baseline year) there were some 1,150 ±54 million hectares of humid tropical forest. Furthermore the 1990-97 period showed a marked reduction of dense and open natural forests: the annual deforestation rate for the humid tropics is estimated at 5.8 ±1.4 million hectares with a further 2.3 ±0.7 million hectares of forest degradation visible from satellite imagery. Large non-forest areas were also re-occupied by forests. But this consists mainly of young re-growth on abandoned land and partly of new plantations, both of which are very different from natural forests in ecological, biophysical and economic terms, and therefore not appropriate in counterbalancing the loss of old growth forests. These new figures are the most consistent currently available. They show that Southeast Asia is the continent where forests are under the highest threat (0.91% annual deforestation rate). The annual area deforested in Latin America is similarly large, but the rate (0.37%) is lower, due to the vast Amazonian forest. The humid forests of Africa are being depleted at a similar rate to that of Latin America. At the global level, these figures indicate a 23% lower net forest cover change rate for the tropical humid forests than was generally accepted until now. This has major repercussions on the calculation of carbon fluxes in the global budget resulting in a terrestrial sink smaller than previously inferred.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book The Conservation Atlas of Tropical Forests written by International Union for Conservation of Nature and Natural Resources and published by Macmillan Reference USA. This book was released on 1992 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa's forests are being depleted at a faster rate than of any other continent. A major increase in the population growth rate began after World War II and it is now running at an annual rate of 2.9 per cent, resulting in massive demands for agricultural land, water, fuelwood and other products. There is no simple answer to environmental degradation and forest conservation must be part of a broader process of managing the landscape. Here to address this topic is the new Conservation Atlas of Tropical Forests: Africa, the first authoritative reference work on this subject. The second in a series this Conservation Atlas follows the format of the acclaimed Conservation Atlas of Tropical Forests: Asia and the Pacific (1991). Part I describes the issues, history of forests and climate, biological diversity, conservation of large mammals, and the peoples of the forests. Included are discussions of the links between population, environment and agriculture, the timber trade, protected areas system and the future for Africa's forests. Part II of the Atlas is a country by country survey of the forests of Africa. Stunning four-color maps, in a 9 x 12 format, have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies. Both maps and text have been prepared and reviewed by a broad spectrum of specialists. The Atlas also includes four-color photographs and sketch maps. They represent the best visual portfolio available of Africa's forests today. For anyone interested in environmental issues, geography, forestry, development, economics, and the African region, this Atlas will be an essential resource.

Available in PDF, EPUB and Kindle. Book excerpt: Reducing tropical deforestation has been a primary focus for the implementation of policies that are aimed at biodiversity conservation, and reducing greenhouse gas emissions, as tropical forests have, biologically, the richest ecosystem on Earth, tropical deforestation is one of the largest sources of anthropogenic carbon emission into the atmosphere, and preventing it is the most inexpensive option, in order to reduce carbon emissions and conserve biodiversity. To set the effective policies and conservation plans to reduce emission from tropical deforestation, the evaluation of effectiveness of both the current and previous efforts for conservation is critical. The three studies in this dissertation describe the development of the methods to accurately monitor pan-tropical forest cover change, using satellite remote sensing data, and their integration with the econometrics approach, to evaluate the effectiveness of the tropical forest conservation practices. The dissertation contributes a method for long-term, global forest cover change estimation from Landsat, and the methods are applied to report the first, pan-tropical forest cover change trends, between the 1990s and the 2000s. The global forest cover change product from 1990 to 2000, which was produced, based on the developed methods which are evaluated to have an overall accuracy of 88%. The results demonstrate that tropical deforestation has accelerated between the 1990s and the 2000s by 62%, which contradicts the assertions of it being decelerating. The results further show that the increased deforestation rate between the 1990s and the 2000s is significantly correlated with the increases in Gross Domestic Product (GDP) growth rate, agricultural production growth, and urban population growth between the two decades. Protected Areas (PA), throughout the tropics, avoided 83,000 ± 22,000 km2 of the deforestation during the 2000s. The effectiveness of international aid can be suppressed by weak governance and the lack of forest change monitoring capacity of each country. The conclusions of this dissertation provide a historical baseline for the estimates of tropical forest cover change, and for the evaluation of effectiveness of such conservation efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests occupy only one-tenth of the world's land area but are home to more than half of the world's flora and fauna. They comprise extremely complex labyrinth of ecological interactions. The astounding richness and biodiversity of tropical forests are rapidly dwindling. There is a fear that the burgeoning human population and industrialization, where a majority of these tropical forests are found, may lead to the clearing or modification or may be a complete disappearance of the remaining tropical forests within few decades. This has severely altered the vital biogeochemical cycles of carbon, phosphorus, nitrogen, and so on and has led to the change in global climate and pristine natural ecosystems. Hence, there is an urgent need to protect, restore, conserve, and improve the forest resources before they are irrevocably lost. In this second edition of the book Tropical Forests, the chapters share the above issues and help in understanding, educating, and creating awareness on the role of "tropical forests" for the very survival of mankind, climate change, and the diversity of biota across the globe. This book will be of great use and could be useful to students, scientists, ecologists, population and conservation biologists, and forest managers across the globe.
