Optimization modelling of conjunctive use of the irrigation water resources for agricultural sustainability

Agriculture is the base to all strategies for planned socio-economic development of most of the countries. Studies have shown that 40% of food production is achieved from 17% of the irrigated areas in the world. As it is not possible to expand agricultural area and possibility of increasing production per unit area of available land and water resources are minimal, it is the need of time that surface and groundwater should be used in conjunction for optimal utilization of water resources.
