Water scarcity and land degradation are emerging threats to global food production. The dry land regions of world are affected by climate change to a greater extent and facing food insecurity. The current pattern of food production has been estimated to be inadequate to meet demands of growing population and required around 38% increase to meet world`s food demands by 2025. Food insecurity in erosion hit dry land regions of Pakistan also demands development of resource-efficient cropping systems to meet the food needs of population growing. The research studies involved different cropping patterns such as fallow-wheat, mungbean-wheat, sorghum-wheat, fallow-lentil, mungbean-lentil, sorghum-lentil, fallow-barley, mungbean-barley and sorghum-barley. The organic amendments involved farmyard manure, NPK, poultry manure, compost and inoculation by phosphorus solubilizing microbes. The effect of cropping systems and soil amendments were evaluated at field scale in terms of water use efficiency measured in terms of economic terms. The results of the studies revealed that double cropping (mungbean-lentil and mungbean-barley) was feasible option in the dryland regions of Pakistan if integrated with the use of poultry manure as alternate environmental-friendly strategy to cut down the use of mineral fertilizers and eliminate summer fallowing.
