Utilization of Small Farm Reservoir (SFR) for Upland Agriculture of Bataan, Philippines

Abstract

To mitigate and adapt the climate change in the hilly areas, rainwater harvesting will solve the water supply problem in the upland. The main objective of the study was to assess and evaluate the performance of the rainwater impounding reservoir as influenced by hydrological, physical and economic factors specifically demonstrate the benefits in the upland agriculture using harvested water from runoff. There were 20 SFR sites established in the Bataan province. SFR capacity ranges from 126.0 m3 to 3,134.0 m3 of runoff or rainfall water. The average production area was 1.0 hectare. The production without the project was 3.25 to 3.45 tons per hectare while with the SFR were 4.05 to 4.25 tons per hectare. The net income was Php 24,777.49. The Payback Period for SFR was 1.76 years to recover the investment in establishing SFR. Some farmer had no production during the second cropping, for them it was not enough to produce crops, better to put fingerlings.
