The issue of water in the Brazilian semi-arid region

Abstract

Soil, climate conditions and socio-economic characteristics in the Brazilian semi-arid region require specific technologies aiming at water resources use and conservation. In addition to the water scarcity condition, incorrect use of water resources in the region enhances the susceptibility to desertification. Impacts of possible climate change may also negatively interfere in the productive processes, health conditions, quality of life and water availability. In this context, non- convention and low cost technologies, with easy assimilation by the communities, must be an approach deal to water scarcity problem and supply diffused population. In the present paper, some of these alternative technologies and the importance for the river basin region integration and water transport across long distances are discussed, highlighting the role of water resources management aiming at conservation and sustainable use.
