Pricing Irrigation Water in Mexico: Efficiency, Equity and Revenue Considerations
The withdrawal of water for i r r igat ion in the d ryer regions of Mexico already accounts for some 91% of potential availabil i ty. Fur ther expansion of i r r igated acreage, therefore, must re ly more on increased water use efficiency ra ther than increased supply from engineering works. A pr ime ins t rument to br ing about such an improvement could be an appropriate water pr ic ing s t ru...
متن کاملIrrigation efficiency and water-policy implications for river basin resilience
Rising demand for food, fiber, and biofuels drives expanding irrigation withdrawals from surface water and groundwater. Irrigation efficiency and water savings have become watchwords in response to climate-induced hydrological variability, increasing freshwater demand for other uses including ecosystem water needs, and low economic productivity of irrigation compared to most other uses. We iden...
متن کاملEffects of irrigation on water use and water use efficiency in two fast growing Eucalyptus plantations
Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...
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...
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...
