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 m<sup>3</sup> to 3,134.0 m<sup>3</sup> 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.
Highlights
Climate change is a significant change in climate in the regions which is result of careless human activities that was observed on common measurements like rainfall, temperature, and air.To mitigate and adapt the climate change in the hilly areas, rainwater harvesting will solve the water supply problem in the upland
Water storage was used in rainfed-growing areas to provide supplemental irrigation water during rainy season and off-season rice production [1]
Aside from irrigation, water in the small farm reservoir could be used for small scale fish production, livestock watering and groundwater recharging [2]
Summary
Climate change is a significant change in climate in the regions which is result of careless human activities that was observed on common measurements like rainfall, temperature, and air.To mitigate and adapt the climate change in the hilly areas, rainwater harvesting will solve the water supply problem in the upland. Water storage was used in rainfed-growing areas to provide supplemental irrigation water during rainy season and off-season rice production [1]. Aside from irrigation, water in the small farm reservoir could be used for small scale fish production, livestock watering and groundwater recharging [2]. Despite of abundance during rainy season, water in the mountains usually goes to rivers down to lakes and oceans when not properly stored or harvested thereby limiting the chance for farmers to store free water from rainfall at any ways when dry season’s rice production will come [3]. Establishment of water impounding reservoir uses the surface runoff to conserve water for productive use and to mitigate climate change. Aside from uses, stored water on the reservoir would use of areas where normally crop production not feasible [5]
