| Abstract: | Water, a valuable asset, needs to be harnessed and well-managed to ensure it is not depleted for future generations, especially in this era of climate change. This requires management actions to ensure efficient use of water resources. In the area of agriculture, indicators are used as benchmarks towards effective and efficient use of water resources. This research uses WaPOR datasets and methodology to determine the efficiency in the water distribution and the delivery of irrigated water on the KIS scheme at the field level for farmers pre- and post-rehabilitation. Based on satellite interpretation and validation, the SOS and EOS used in this assessment were June to October for the major season and November to March for the minor season. The seasonal distribution of rainfall within the scheme shows varying trends which should be taken into consideration in the scheme’s plans for the seasons. The performance indicators generally show a fairly uniform scheme with adequate distribution. The beneficial consumption seems good which could be attributed to better management practices. However, there were uncertainties with the outcome of the water productivity. This is largely due to the discrepancies between the WaPOR yield and the yield from the stakeholder survey. |
