An overview of the results of several recent field studies on water management and distribution in the Philippine provinces of Laguna, Bulacan, and Nueva Ecija is presented. The diversion irrigation systems studied ranged from 3,600 to 75,000 ha in size. Factors found to have insignificant influence on the performance of the systems are farm-ditch density, the distances of farms from turnouts, and the rotation of water supplies at the farm level. But the location of farmers' fields along distribution canals and the rotation of water supplies among laterals or sublaterals markedly influenced the performance of the systems.

The effects of location and hydrologic factors on drought occurrence in the 5,700 ha command area of a lateral in the Philippines' Pe$aranda River Irrigation System were studied. Greater moisture stress was observed on fields located further along major canals. Minimum water requirements for rice increased substantially when fields were allowed to dry out and crack during periods of water scarcity because of increased seepage and percolation through the cracks when water was resupplied.

The interpretative summary reviews the observations and impressions of the authors from a seminar on Policy and Management Issues in Irrigation Systems in Southeast Asia. The three basic issues that were discussed at the seminar were (1) alternative strategies to develop irrigation infrastructure; (2) alternative approaches to improve the operations and maintenance (O&M) of irrigation systems; and (3) specific policy options in irrigation development.
