Other authors suggest that subsidies can be justified because irrigation projects provide both public and private goods, or that higher water prices will reduce agricultural net revenues without motivating notable reductions in irrigation diversions. Those authors often cite the low elasticities of demand for irrigation water observed in many settings. When demand is price inelastic, quantity demanded declines by a smaller proportion than an increase in price, such that revenues collected from water users increase substantially, with little change in the volume of irrigation water used.
