Problems in Irrigation in the Philippines
* The level of irrigation development is very low * The existing large gravity irrigation system have continuously been performing inefficiently and below expectations * The sub-optimal performance is due to interrelated technical, hydrologic, socio- economic, institutional, environmental and political issues and constraints besetting the national efforts towards accelerated irrigation development
26
* transfer of the management and administration of irrigation systems to irrigator’s associations
NIA Rationalization Plan (2008)
27
* strengthen the autonomy and empowerment of local government units (LGUs) * Transfer of the management of irrigation systems (CIS) to LGUs
Executive Order No. 138 series of 2021 (Mandanas Ruling)
28
(Republic Act No. 10068)
Organic Agriculture Act of 2010
29
(Republic Act No. 10969)
Free Irrigation Service Act (FISA) of 2017
30
* The potential benefits from irrigation development in the country have never been fully harnessed
Present State of Irrigation Development
31
2.0 million ha - total service area (64% of potential) 0.93 million ha – NIS 0.72 million ha – CIS 0.18 million ha – PIS (Private IS) 0.17 million ha – OGA (other government agency)
NIA annual report (2020)
32
Issues on and constraints to sustainable irrigation development (David, 2003)
◼ Performance of gravity irrigation systems and irrigated agriculture ◼ Sub-optimal Use of Water ◼ Recycling wastewater for agriculture ◼ Cost-effectiveness and suitability of current irrigation technologies ◼ High cost of irrigation development ◼ Subsidy, irrigation service fee (ISF) and sustainability ◼ Water Rights and water pricing ◼ Policy framework for water resources ◼ Credit for small-scale irrigation development ◼ Institutional arrangements/mechanisms ◼ Public sector’s capacity to perform essential services and functions in support of the timely adjustments in policy and policy instruments ◼ Role of Farmers and Water Users Organizations and LGUs ◼ Fragmentation of irrigation development activities
33
To achieve accelerated and sustained irrigation development... (David, 2003)
◼ Development of New Irrigation Systems ◼ Rehabilitation of National and Communal Irrigation Systems ◼ Improving the Performance of Irrigated Agriculture ◼ Farming Systems Diversification and Intensification ◼ Enhanced Institutional Capacity ◼ Research and Extension
