Abstract

This paper, the ninth in the IIASA water demand series, reports on the analysis of water demands of a large agroindustrial complex in the northeastern part of Bulgaria, covering a territory of about 2,700 sq. km, with a population of some 175,000. With the aid of SWIM (Silistra Water for Irrigation Model), which was developed at IIASA, several factors that both influence agricultural production and associated water demands have been analyzed. The major goal of the Silistra complex, to maximize the total crop and livestock production within the limited regional resources, has been taken into account in the analysis. The model allows analyses to be made of substitution possibilities in agricultural production (water for fertilizers, irrigated for nonirrigated crops, one sub-region for another, and so on). The work leads ultimately to determining an economically efficient level of irrigation development.
