OBSERVATIONS / REMARKS
The area is basically has high potential for
animal production and domestic water use .
A detailed plan and support system for implementing water management strategies in Kenya's Ngoroglowa Rock Catchment area, with analyses of current water usage, future demand projections, potential maps, classification of interventions, and associated costs and efficiency. The area shows high potential for animal production and domestic water use.
