Optimization of water resources for cropping pattern under sustainable conditions through fuzzy logic system

Abstract

The optimization problem attempts to find a suitable combination, out of many feasible combinations of resources and their allocations, which maximizes a benefit or minimizes a cost subject to given constraints expressed through simple linear algebraic expression or equations. The Fuzzy Interface System (FIS) has many applications in water resources engineering. It has been used for planning the conjunctive use of surface water in canal command regions. The proposed FIS supports the cooperation between water administration and water users, and the cultivators in relation to revising cropping patterns. Fuzzy system modelling considers the fuzziness in the variables, which can be implemented in the field. The degree of satisfaction gives the reliability of the fuzzy modelling. In the earlier studies, many researches have included the fuzziness in a linguistic form and also included either in the inflow or in the demand. Hence, it is felt necessary to carry out study on development and application of fuzzy logic systems in context with the sustainable development. The model was used in command regions under the Pench irrigation project of Maharashtra State, India for determining optimal cropping activities during kharif, rabi, and hot weather seasons so as to maximize economic returns to the agricultural producers by making most efficient use of surface water resources at different reliable flow conditions. © 2007 WIT Press.
