Evaluation and comparison of the water footprint index of crops in Khorasan Razavi, Kerman and Isfahan provinces

Examining the current situation of agriculture shows that despite the potential to increase the agricultural products, due to the lack of a proper management system, the possibility of optimal use of water and soil resources has not been possible. In this regard, it is necessary and necessary to examine the solutions for optimal use of water through a review of the allocation of water resources and its management. In this research, using the evaluation of the water footprint index, the water footprint of alfalfa, watermelon, fodder corn, wheat, rapeseed, cucumber and onion products in Razavi Khorasan, Kerman and Isfahan provinces were calculated and compared with each other to determine Which province has more favorable planting conditions for each product from the point of view of the water footprint index.Uneven distribution of rainfall and lack of water in many parts of the world have created many problems for the production of agricultural products and even the provision of safe drinking water. As some scenarios predict, by 2025, 60% of the world's regions will experience water stress due to the increased use of water resources. Most of these regions are located in Africa, Asia and Latin America.Therefore, due to the lack of proper time and place distribution of rainfall, agricultural management to increase the efficiency of water consumption is much more difficult than in countries with favorable water conditions.
