Demanda para a aquicultura: desafios legais e institucionais ante os múltiplos usos na gestão dos recursos hídricos no baixo curso do Rio Paraíba.

Abstract

Water resources are increasing their visibility in multiple areas of knowledge and challenging the management bodies. This fact affects the territories in different ways. It is often explicit the inability of Public Water Resources Policies to resolve conflicts over water use. The present work aims to support the water resources management in the Lower course of the Paraíba River, based on specific water permits for aquaculture throughout the state. The study uses a water allocation database for the year 2019 downstream of the Acauã dam (Itatuba, PB) and upstream of the Campo Grande dam (Itabaiana, PB). Therefore, according to the water availability and the regularized volume to water demands, a divergence between water supply and water demand was found. In consequence, there are different conflicts due to priorities of the service versus other consumptive uses. With the effects generated by the disharmony in the distribution of water in the region, it is necessary to implement regulations to minimize the impacts arising from such an imbalance. This effort justifies the work scenario, above all, in the research for the legal framework of a state with a historical water complex reality ruled mainly by scarcity and drought.
