A satisfação das necessidades hídricas humanas e ambientais é um tema que tem merecido atenção no âmbito da gestão e planejamento dos recursos hídricos no mundo. As incertezas sobre as possiblidades de atender as necessidades de água futuras na bacia do rio Inhanombe motivaram a realização deste trabalho. Este artigo tem como objetivo avaliar a capacidade de satisfação das necessidades de água, através da aplicação do WEAP (Water Evaluation And Planning System). Simularam-se três cenários: o cenário de referência que corresponde a exploração atual dos recursos hídricos; dois cenários de impacto: Médio e Alto crescimento que correspondem à expansão da área irrigada e do crescimento populacional entre 2019 e 2040. Os resultados obtidos demonstram a incapacidade do sistema de satisfazer as necessidades futuras nos cenários de Médio e Alto crescimento com níveis baixos de garantias mensais e muitas falhas no fornecimento.
Water Allocation Assessment in the Inhanombe river basin, Mozambique
A B S T R A C T
Meeting human and environmental water needs is a topic that has deserved attention in the area of water resources management and planning in the world. Uncertainties about the possibilities of meeting future water needs in the Inhanombe river basin motivated this work. This article aims to evaluate the ability to meet water needs through the application of WEAP. Three scenarios were simulated: the reference scenario that corresponds to the current exploitation of water resources; two impact scenarios: Medium and High growth corresponding to the expansion of irrigated area and population growth between 2019 and 2040. The results show the system's inability to meet future needs in medium and high growth scenarios with low monthly guarantee levels and many supply failures.
Keywords: Water demand, river basin, Inhanombe river, WEAP.
