| Summary: | The increasing awareness of regional climate and water-cycle changes are putting under pressure the efficient water use in agriculture. In developing countries, a reliable supply of energy is the key factor to enhance agricultural productivity and water efficiency. A neat water resources management is required for building flexibility, adaptable water distribution and reducing the extra amount of energy used. The “water-energy nexus” is a fundamental aspect for future planning and policy. The paper sheds the light on the application of an integrated methodology based on a DSS knowledge, aiming at improving the water delivery service, energy and costs optimization. The hydraulic simulation modelling is combined with an economic analysis, related to the yearly cost of energy, crops profitability and the impact of energy savings to the cost production. The analysis revealed that the application of this methodology focus on irrigation schemes critical aspects, providing optimized solutions for future policies.
