Abstract    Modern irrigation systems are considered as a way to both respond to the effects of climate changes and improve the water security. Applying such systems, save the water used in farming activities and consequently made some environmental challenges in terms of increasing energy consumption and greenhouse gas emissions. Although some recent studies analyzed the relationship between water and energy in the agricultural irrigation systems, considering the objectives on productivity, adaptation, and mitigation in a cropping pattern optimization problem is necessary. ClimateSmart agriculture as a strong programming concept, addresses these three objectives and has created the potential for a &triplewin& solution. This study is an effort to fill the study gap on triplewin solution in modern irrigation by developing an integrated economichydrologicalenvironmental model called WECSAM at the basin level using a hydrological model called WEAP. For this purpose, a multiobjective optimization model has been developed with the concepts of water footprint, energy footprint, and the greenhouse gas emissions in the context of CSA. We applied the model to the northern region of Bakhtegan basin called Doroodzan irrigation network located in Iran. The result of the WECSAM model indicated that by simultaneously optimizing the conflicting objectives of maximizing profit and minimizing water footprint, energy footprint, and CO2 emissions, as compared to the singleobjective model of maximizing economic profit, the water footprint decreases by 8.2%, Energy footprint decreases by 21.2%, CO2 emissions decreases by 6.9% and profit decreases by 7.4%. The share of each system in irrigating the watersmart, energysmart, and climatesmart cropping pattern is as follow: 54% for drip system, 26% for semipermanent sprinkler system, 11% for surface systems, 8% for centerpivot, and <1% for classic permanent sprinkler system.
