Estimativa da demanda de água em usos prioritários no setor rural da região do Alto Paraíba e na sub-bacia do Taperoá.

Abstract

The granting of water use rights is one of the control instruments of the Brazilian Water Resources Policy (Law No. 9.433 / 97). In this sense, the input and output information of the water system is fundamental for effective management control. The contributions for human supply and animal desedentation are highlighted with priority uses in the referred Law. The present work refers to the estimate of priority water demand, integrating rural and livestock human consumption in municipalities located in the Alto Paraíba and Sub Taperoá basin, both belonging to the Paraíba river basin / PB. Thus, the comparative analysis of the proportions of these consumptions against the total demand in the sector stands out. To this end, we used the 2006 Agricultural Census database and 2007 and 2010 population data, all from the Brazilian Institute of Geography and Statistics - IBGE. Integrating a comparative approach with information on availability indices of the Paraíba State Water Resources Plan - PERH 2006, make up the importance of the quantity of such demands in the management of water resources in the studied hydrographic regions.
