In the context of economical pre-feasibility study for the design of an irrigation system, CEMAGREF has developed a methodology and carried it out in the Nord-Sommierois region (Gard - South of France). Its main daim is to evaluate the medium run agricultural water demand in order to fit water requirements, at the scheme scale, and water ressources (supply). The methodology is based on the analysis of farm management, focusing on agricultural supply modelisation, using linear programming. Simulations are implemented with different scenarios of changes in the economical and irrigation context. Results are given for two scenarios. This methodology can be considered as a decision support tool for the technical and financial design of irrigation systems. Its use should be restricted to pre-feasibility studies on small areas (around 200 farms).
