Agro-hydrological Evaluation of On-Farm Rainwater Storage Systems for Supplemental Irrigation in Laikipia district, Kenya

Knowledge partner:

The main objective of the study was to evaluate the hydrological and economic performance of farm ponds with the view of assessing their contributions to water and food security in semi-arid agro-systems of Kenya. Agro-hydrological evaluation of on-farm runoff storage systems entailed field survey, monitoring of water losses, analysis of rainy seasons and dry spell occurrence, soil moisture and water balance, estimation of supplemental irrigation requirement and farm-level cost-benefit analysis of cabbage production using low-head drip irrigation system.
