Estimativa da demanda hídrica na pecuária no Cariri Ocidental Paraibano.

Abstract

Based on the first principles of sustainable development, watershed management is a complex task, involving many aspects related to water control and maintenance, as well as guarantees of care for future generations. The demand information is fundamental for the water management in a hydrographic unit, being important input contribution of the water system. The present research is focused on the estimation of water demand for the animal husbandry sector. The area of study involved municipalities of the Western Cariri of the state of Paraíba/Brazil, comprising the Alto Paraíba Region and the Taperoá River sub-basin (both sub-basin springs regions of the Paraíba river/PB/Brazil). The data were related to the quantitative goats, sheep, cattle, horses and pigs BEDA (Equivalent Cattle for Water Demand) methodology was used, which was used in the State Water Resources Plan of the state in 2006. To quantify the quantitative impact of the simulation, the results were compared with the maximum volumes of dam related to each municipality.
