Institutional and policy analysis of river basin management : the Jaguaribe river basin, Ceara, Brazil

Abstract

"The authors describe and analyze water resources reform and decentralization of river basin management in the state of Ceara, Northeast Brazil, the poorest part of the country. The Jaguaribe river basin is located entirely within the state of Ceara. With a drainage area of 72,560 square kilometers, it covers almost half of the state's territory. The basin has 80 municipalities and more than 2 million people, about half rural and half urban, in primarily small towns, representing about a third of Ceara's population. Precipitation in the basin is highly variable, ranging from 400 mm in the hinterland to 1,200 mm along the coast. Rivers in the basin are ephemeral and only flow during the rainy season. The key water management challenge is to capture the water in reservoirs in rainy years and to manage it such that it will last for several years, in case the following years are drought years.
