Irrigation is a key component of the government`s strategy to improve agricultural productivity and attain food self-sufficiency. In recent years, the government has been investing in deep-well pumps as an option to develop more water sources amid the expansion of service areas. This study undertakes a rapid appraisal of deep-well pump projects in several national irrigation systems in Central Luzon, operated by the National Irrigation Administration. It also provides a preliminary assessment of the suitability of such investments. It then lists down some lessons that should be considered to improve planning and implementation of irrigation projects.
