The primary objective of this research and development project is development of irrigated rice production system design procedures for the project area. The proposed improvements on the irrigation and drainage system, and production schedule must take maximum advantage of the existing system physical facilities. This means the proposed enlargement of primary water conveyance systems bust be kept to a minimum. It is expected that the procedures developed will be applicable to similar projects within the Bicol River Basin. The project is also expected to establish terminal water distribution systems and management strategies that are uniquely suited for the Bicol River Basin. Furthermore, maximum utilization of available labor is required to reduce the severe unemployment and underemployment problems currently existing in the Basin area.
