Abstract

Sustainability of Cuban agriculture faces great challenges in a lower water availability horizon due to the decrease in rainfalls by the effects of variability and climate change for Cuba. This work is a first approach to the application of WEAP model as a tool to support decision making in the integrated management of water resources in the municipality of Los Palacios, in western Cuba, highlighting its potential in support of the adaptation to climate change of the local agricultural sector. The conceptual models of the basins in the municipalities San Diego, Los Palacios and Bacunagua, were generated with WEAP, which feed a general model that is visually aggregated but in its databases retains the disaggregated approach per user and per group of crops and allows these basins to be treated as a system, since the hydraulic infra- structure that connects them works like a single basin. The generated conceptual model of water management in this municipality under the hydrological planning approach has as main features that the variation of demand is analyzed on a monthly basis and allows to describe the sowing calendars of the crops and the particular practices of the farmers, and also the analysis of runoff by sub-basins and estimate unregulated runoff, water losses by conduction in the systems and the possibility of water reuse within the irrigation zone.
