![]() Moreover, water and yield obtained at the farm level were determined. Better policies on water resources utilization in the Philippines Ĭontact Information Dr. The task involved measurement of irrigation water flows to determine the amount of water abstraction, inflow (head) and outflow (tail) between the canals to determine the conveyance efficiency of the main, secondary, and tertiary canals of the traditional irrigation systems.Revisit and implement the provisions of AFMA that are geared towards water use efficiency.Better coordination among agencies, organizations and other entities that develop, manage and use water resources in the country.Prioritization of minor irrigation systems.Organization and/or strengthening of irrigators association.Proper design of new irrigation systems to incorporate measures for increasing water use efficiency.Provision of the necessary water control structures in existing irrigation systems.Provision of adequate institutional and financial support for research and technology promotion.Continued research and development on efficient irrigation technologies and practices.DA is mandated by AFMA to coordinate with DENR in the preservation and rehabilitation of watersheds to support irrigation systems.AFMA stipulates that irrigation research and development shall be pursued and priority shall be given to the development of effective, appropriate and efficient irrigation and water management technologies.DA is mandated by AFMA to formulate and develop a plan to promote minor irrigation systems e.g.The Agriculture and Fisheries Modernization Act (AFMA) of 1997 (R.A. The planning, design and management of communal irrigation systems are to be devolved to LGUs with NIA providing technical assistance.NIA is mandated by AFMA to plan, design, develop, rehabilitate and improve the National Irrigation Systems.Relevant Provisions of the Agriculture and Fisheries Modernization Act (AFMA) of 1997 (R.A. Low priority given to minor irrigation systems (STWs, LLPs, SFRs).Issues and Problems in Irrigation (cont’d.)
