Sustainable conjunctive use of groundwater for additional irrigation
Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...
متن کاملGroundwater management for Lower Indus Basin
The present study aims to find out an optimum policy for pumping out the optimized volume of groundwater obtained from the authors' earlier Two Level Optimization Model [N.K. Garg, A. Ali, 1998. Two level optimization model for Lower Indus Basin. Agric. Water Manage. 36, 1±21] for the Dadu Canal Command of the Lower Indus Basin. It is shown that the tubewells in this canal command may be operat...
متن کاملEnergy supply and the expansion of groundwater irrigation in the Indus-Ganges Basin
Irrigation using groundwater has expanded rapidly in South Asia since the inception of the Green Revolution in the 1970s. Groundwater currently represents the largest source of irrigation in the Indus-Ganges Basin (IGB), which feeds over one billion people and provides direct livelihoods for hundreds of millions of farmers. Although abundant in absolute terms, groundwater is overexploited in th...
متن کاملSimulating and Optimizing the Conjunctive Use of Surface and Groundwater Resources Using the System Dynamics Approach (A Case Study: Dashte-Abbas Irrigation Network)
The construction of irrigation network and the water transfer from Karkheh Dam to Dashte-Abbas, due to neglecting the groundwater resources has increased groundwater level and waterlogging of the agricultural land in the recent years. The aim of this study was, therefore, to optimize the conjunctive use of surface and groundwater resources in Dashte-Abbas to minimize waterlogging problems and a...
