Simulated Crop Yields Response to Irrigation Water and Economic Analysis: Increasing Irrigated Water Use Efficiency in the Indian Punjab
The Indian Punjab has been heralded for its technical achievements but increasingly criticized for leveraging its success on the environment. Irrigation has been one of the main pillars of the Punjab's Green Revolution. The availability of water has pushed rice and wheat productivity to new heights. Cheap water policies have enabled farmers to exploit groundwater. Water tables are shrinking in ...
متن کاملIncreasing agricultural water use efficiency to meet future food production
With the world’s population set to increase by 65% (3.7 billion) by ∼2050, the additional food required to feed future generations will put further enormous pressure on freshwater resources. This is because agriculture is the largest single user of fresh water, accounting for ∼75% of current human water use. At present ∼7% of the world’s population live in areas where water is scarce. This is p...
متن کاملA Worldwide Comparison of Water Use Efficiency of Crop Production
Worldwide food security and water safety issues necessitate countries with low water use efficiency of crop production (CWUE) to increase it and reduce regional CWUE variations. CWUE function was estimated with stochastic frontier analysis, and CWUE variation was decomposed on inter-continental, intra-continental and international level with variance decomposition method. It is proposed that in...
متن کاملIrrigation Pumping Plant Efficiency
Rising energy costs have increased the cost of pumping to the point that many farmers are finding irrigation to be unprofitable or only marginally profitable. Fortunately, however, pumping costs are an item that farmers have some degree of control. Pumping costs often are higher than they need be for two reasons: 1.) more water is pumped than is necessary, and/or, 2.) the pumping plant operates...
متن کاملWATER USE EFFICIENCY Deficit irrigation in grapevine improves water-use efficiency while controlling vigour and production quality
Grapevine irrigation is becoming an important practice to guarantee wine quality or even plant survival in regions affected by seasonal drought. Nevertheless, irrigation has to be controlled to optimise source to sink balance and avoid excessive vigour. The results we present here in two grapevine varieties (Moscatel and Castelão) during 3 years, indicate that we can decrease the amount of wate...
