The present system of pricing of irrigation water in the gravity irrigation systems of the Philippines results in inefficient allocation and use of water. Furthermore, the low price of water results in the capitalization of irrigation benefits into land values. Hence, landowners are the major beneficiaries. Gradually increasing the price of water so that it is more in line with its opportunity cost under optimum management would improve the economic efficiency of water use and encourage the collection of government revenues for further public investment. As soon as practicable, water should be metered directly to farmers' paddy fields and the water charged based upon the amount actually diverted.

A survey of 52 small-scale pumping units in Quezon and Batangas provinces in 1971-72 reveals that pump irrigated rice farms had positive net returns, with the wet season returns slightly greater than those of the dry season. But pump systems in the study areas performed poorly. They had low pump discharge rates and served limited areas. Four inch pumps had a greater average pump discharge than 5-inch pumps operating even at lower revolutions per minute. No substantial differences were found in yields of farms irrigated from different water table depths, or of different soil types. There were significant differences in pump discharge among soil types although they were not significant with respect to depth of water table. It was also found that area served was more dependent on available irrigable land than on soil type or water table depth. The study revealed that water is often conveyed through poorly maintained earth canals which we believe considerably reduced the efficiency of water use. The most common method of irrigation fee payment is 20 percent of net product shared by the tenant and landlord in both the wet and dry seasons. The major problem of pump owners is the lack of cash for pump repairs.

The reservoir-supplied Upper Pampanga River Project in Central Luzon, Philippines, was completed in 1975. It has a command area of about 83,000 ha. A preliminary study showed the project to be economically viable, but the 1974-75 surplus income from rice production was found inadequate to fully cover farm production costs, family expenses, and current irrigation fees.

The economic performance in 1974 of seven diversion irrigation systems ranging in size from 2,400 to 9,000 has is compared with their performance as initially projected. Construction costs are generally about 15% higher than originally projected, operation and maintenance costs are about 55% higher, and farm income benefits from irrigation are about double. The greater farm income benefits stem from the much higher rice prices in 1974 than those that were projected. Area irrigated and yields were both substantially below projected levels.
