K. de aAn approach to the sustainable use of the natural resources of the Pantanal, Upper Paraguay Basin, Brazil. c2003 aWetland Stewardship: Changing Landscapes and Interdisciplinary Challenges. aPantanal is one of the largest continuous freshwater wetlands of the world, with 140.000 square kilometers in Brazil, located in the Upper Paraguay River Basin, in the central area of the South America. The low slope, 3-5cm/km from north to scuth and 12-15cm/km, from east to west, means the flood that begins in the north, lasts to three months to cross the Pantanal. The predominant soils are sandy, except in the southeastern part when clay soils predominante. The vegetation is predominantly from savannas "cerrado", with elements from Amazon along the Paraguay River, and from Mata Atlantica and Chaco, in the southern and southwestern regions. The climate is very hot in almost of the year, with some episodic cold temperatures in the winter. Water level in the main river and its tributaries varies along the year and between years, depending on the rain that falls on the plain and on the highlands. Biological diversity comprises 1,800 plant species, 270 fish species, 700 birds, 90 mammalians, 162 reptiles and more than 1,200 butterfly species. Popauilation density comprises 20 million caimans, 400,000 capybaras, 36,000 marsh deers, 41,000 pampas deer, 5,000 fiant anteaters and 15,000 active nests of jabiru storks. The most important economical activities are the beef cattle rainsing based on native pastures and the fishings, mainly sport fishing. Ecological tourism is just trying to grow. So, it is a big challenge to Embrapa Pantanal to promote the research needed for the sustainable development one of the most unique ecosystems in the world. aBrazil anatural resources aPantanal aRecurso Natural aBacia do Alto Paraguai aSustainable use aUpper Paraguay Basin aUso sustentavel tIn: ANNUAL MEETING SOCIETY OF WETLANDS SCIENTISTS, 24., 2003, New Orleans.
