Impact of AFMA on irrigation and irrigated agriculture

Abstract

Compliance with the provisions and stipulations of the Agriculture and Fisheries Modernization Act (AFMA) on irrigation had been very minimal. As a result, AFMA had very little positive impact on irrigation and irrigated agriculture. After 5 yr of implementation of AFMA, the engineering performance of existing gravity irrigation facilities continued to be mediocre. In terms of cost-effectiveness, irrigation service area and irrigation intensity, AFMA had negligible impact. However, there seems to be a modest increase in the yield of irrigated rice from pre- to post-AFMA years. Despite a massive investment of over PhP5.5 billion per year on national and communal irrigation systems, the aggregate service area of such systems increased by only 9,000 ha per year from 1998- 2004. The existing systems are deteriorating at a rate of about 134,000 ha per year. There was no improvement in irrigation intensity in the national irrigation system (NIS) and communal irrigation system (CIS) service areas. To gain insights on the reasons behind the poor engineering performance of existing irrigation systems, field studies on sample irrigation systems selected at random were conducted. The results of the studies in the sample province of I locos Norte in the Philippines showed an average irrigation intensity of only 27% during the dry season. This low rate was traced to design mistakes and over-optimistic estimates of the irrigation service area during the planning stage. The impressions and expectations of stakeholders on the irrigation component of the Act conform to the findings on the tangible impact of AFMA.
