Utilizacao de aguas subterraneas em aluvioes no Agreste Pernambucano.

Abstract

In a semi arid scenario under salinization risk, in the Northeast region of Brazil (Pernambuco State), three areas have been investigated in a study of groundwater use for agriculture, livestock and human supply. Adopting a methodology of interviews and field surveys it has been possible to verify that selection criteria for groundwater are applied only in periods of large water resource offers. In other situations there is no restriction for use, except when required for human supply. In the situations of water scarcity, in the three analyzed areas, irrigated crops give way to livestock supply, which in periods of drought present more income than attempts to irrigate with high salinity levels. The communities, specially the settlements, are dependent on state official programs of financial support to develop the irrigation and the scarcity of financial resources is a limiting factor for technology implementation. The farmers motivation for innovation in processes and technologies has occurred slowly, but gradually. The acceptance of 'know how' offered by the research team has occurred with positive results. This work is part of a proposal of management of the water resources for sustainable use, through participatory process.
