Abstract | Increasing water productivity of irrigated rice remains the most promising challenge to tackle the increasing water scarcity problems. The aim of this study is, therefore, to measure scale effects on water productivity through water accounting coupled with remote sensing and geographic information system (GIS) in rice-based irrigation system of District I of the Upper Pampanga River Integrated Irrigation System (UPRIIS), Philippines. The water accounting is applied at five different spatial scales to study water savings and impacts on different scales. The spatial scale ranges from a micro scale at the size of farmers field (area of 1 ha), to sub-irrigation canal scale (10,000 ha) and a system scale (area of 18,000 ha) covering the entire District I area. Daily measurements of all surface water inflows and outflows, rainfall, evapotranspiration, and amounts of water internally reused through check dams and shallow pumping are summed into seasonal totals, from November 19, 2000 to May 18, 2001 for five spatial scale units ranging from 1 to 18,000 ha. Water accounting technique is applied to measure performance indicators of the water productivity at each spatial scale. |
