Water Intervention Plan in Urum-Loima Region
This water intervention plan in the Urum-Loima region focuses on addressing water gaps and potential zones for groundwater exploration. It includes related interventions such as open water storage and sand dams to meet current and future water demands for domestic, livestock, and agricultural use. The plan identifies suitable interventions based on water user groups and intervention quantity and quality. Additionally, potential yields and costs are compared for different intervention options in the region.

COMMENTS Its difficult to quantify spate irrigation and thus its hard to get the cost of the intervention sand dams are used by all the user groups and so its viable and a number of them can be constructed Urum is a dry season grazing area and migratory route and therefore need to have adequate water sources
