Crescimento econômico e pressão sobre recursos hídricos

Resumo

This paper aimed, through an inter-regional input-output matrix (estimated for 2004) inan ecological-economic model, simulate three scenarios of future demand (for 2020) forthe use of water resources in river basins Piracicaba-Capivari-Jundiaí (PCJ), Paraiba do Sul(PBS), Alto Tiete (AT) and Sorocaba and Mid Tietê (SMT). These simulations are based on thehypothetical expectations of changes in the final demand of goods in the economy, resultingin a comparison between estimates results of demand for water with the hypotheticalwater availability. The growing shortage of water resources motivates studies on analysisof the demand, especially with a view to proposing sparing strategies. The simulation results showed water amounts that depict important water shortage in AT and SMT basins,which is a problem that has been around for a few decades and can become even worse. Inaddition, water shortage was identified in the PCJ basin mainly due to water transpositionsto other river basins, especially AT covering the entire metropolitan region of São Paulo.
