Proposta de um modelo de gestão para o uso eficiente da água numa escala de tempo plurianual: um estudo de caso com os colonos do perímetro irrigado de São Gonçalo no Sertão Paraibano.

Abstract

Water is a natural essential resource to life on earth and, as economic activities emerge, increasingly requires water in quantity and quality. To mitigate and equating this problem is necessary a management model of efficient and improved water demand. Thus, the general objective of this research is to propose a management model that promotes the adaptation of the efficient use of water, in a multiannual time scale, to the settlers of the Irrigated Perimeter of São Gonçalo, located in Paraiba backlands, looking at minimization of the drought effects. The methodology used in the research was bibliographical, exploratory, case study and on-site visit by a qualitative and quantitative approach. Considering the data collected and the methods for the calculation of water demands were obtained the results on a multiannual scale, in which was chosen and proposed to the social technology called claypit trench modified (BTM). That technology, besides minimizing the rate of infiltration and evaporation, will allow the storage of water to supply the water need of a family with five people that could develop fish farming activities, livestock and irrigated agriculture in dry periods, for 3 years. So if this management model is implemented and has technical monitoring, will teach the local settlers to live with the drought, moreover, will minimize the exercised pressure on the water system of São Gonçalo and Engenheiro Àvidos.
