Analysis of the water supply-demand relationship in the Sinu-Caribe basin, Colombia, under different climate change scenarios

Abstract

The water resource supply-demand relationship in the Sinu-Caribe Basin, Colombia, was analyzed based on current values and values projected for 2015 and 2025 by the Instituto de Hidrologia, Meteorologia y de Estudios Ambientales de Colombia). The projections included estimated changes in the relationship based on general circulation climate change models under A2 greenhouse gas emission scenarios. The WEAP (Water Evaluation and Planning) System was applied to analyze and simulate different water systems and to guide management policies in order to provide tools, criteria and decision-making elements for devising adaptive strategies under adverse conditions.
