Considering that agriculture is the largest consumer of water resources in the world, if humanity wants to face the challenges that are ahead of it in the future, it must reduce the amount of water consumption in the agricultural sector to sustainable consumption. Agriculture as the main water consumer in Minab city has attracted a lot of attention. This study was carried out with the aim of estimating the water footprint in the agricultural sector of Minab city to optimize the crop cultivation pattern. so; First, the water footprint was estimated in the introduced components (blue, green and gray) and based on the net benefit and yield, economic value and land value were estimated for each category of agricultural products, and then with the aim of reducing the water footprint and increasing the net benefit Cultivated area of each category of products (legumes, garden, oilseeds, fodder, cereals, jalizi, vegetables) during 1386 to 1400 in two scenarios of optimizing the cultivated area based on benefit maximization and optimizing the cultivated area based on the ratio of footprint to benefit , was optimized. The results showed that by applying the net profit maximization scenario (the first scenario), the cultivated area decreases by 12% and the agricultural production and water footprint increase by 61% and 13%, respectively. A very slight change (5% decrease) can be seen in the net profit, but in the second scenario, with the aim of maximizing the net profit compared to the footprint, the cultivated area decreases by 12%, agricultural production increases by 79%, and the volume of water footprint decreases by 11%. A very minor change (5% decrease) can be seen in the net profit, so the water footprint perspective in the composition of agricultural products in the region has been significantly effective in water security.
