These include water pricing based on ability to pay rather than marginal cost, financing mechanisms in which cross subsidies from hydropower charges finance irrigation development, pricing irrigation water below the marginal cost of supply, the potential for irrigators to renegotiate contracts after projects are built, and the incentive to overinvest in irrigation when irrigators believe they will secure a water right. Five factors were also identified that lead to a higher value of infrastructure maintenance. These include a lower price of water charged to irrigator, a lower real cost of repairing infrastructure, a greater water savings from infrastructure maintenance, higher crop yields produced by saved water, and a lower cost of capital.
