Tropical Freshwater Wetlands

Wetlands could be described as land and water at Tropical wetlands: one and the same time, and as such are very specific on the brink ecosystems. Their often rich variety of resources makes them highly valuable to the peoples who live With a few exceptions (like the Everglades in the or regularly stay in them. However, access to them United States), the last remaining large wetlands are to be found in developing countries. Perhaps this can is difficult and those unaware of their services be explained by insufficient financial resources, frequently associate wetlands with such nuisances and calamities as mosquitos, disease, floods, impen lower popUlation density or a different concept of etrable wastelands, etc. As a result these areas are development and well-being. Whatever the reasons, often perceived as obstacles to human development many tropical wetlands still exist and support the and well-being. subsistence of many communities. But for how much History reflects these two views. Wetlands may longer? have been the cradle of great civilizations (like the During the last few decades tropical wetlands Maya, Inca, Aztec, Nilotic and Mesopotamian have also been destroyed or considerably altered. Dams and embankments now prevent water from civilizations), but elsewhere their destruction allowed other societies to develop. For example the Nether spreading into the floodplains of several rivers, like lands literally 'emerged from the waters' thanks to the Senegal, Volta and Nile.

Tropical Freshwater Wetlands deals with the sustainable management of some of the most valuable environmental assets available to developing countries, i.e. floodplains, marshes, swamps and shallow water bodies. The main types of tropical freshwater wetlands are described, their value is highlighted, and human intervention and its impact on wetlands are reviewed. A general approach to, and guiding principles for the sustainable management of these particular ecosystems are then proposed. Finally, sources of expertise and further information are indicated. The practical character of Tropical Freshwater Wetlands is enhanced by thirteen case studies in which seventeen specialists report on wetland management `in the field', a literature list which includes some 900 entries, data on more than 150 experts, and a system of indexes facilitating access to information and know-how. Together, these features make Tropical Freshwater Wetlands the first publication of its kind. Audience: An invaluable reference book and guide for all those who are interested in development or natural resources management planning at the subnational level.
