This report evaluates the impacts of climate change on water and sanitation technologies in the peri-urban areas around Lake Naivasha, reviews the water resources in Lake Naivasha and considers the potential adaptations required to mitigate the impacts. Under current forecasts of climate change, the mean temperature in Kenya is predicted to increase while precipitation is expected to decrease in volume and increase in intensity, increasing the frequency and severity of droughts.
The main impacts are identified as:
Decreasing lake and ground waters: will have a significant impact as there will be higher domestic demand whilst surface water availability decreases
Increasing lake and groundwater levels is largely positive for Naivasha as there is more water for domestic and irrigation use.
Potential short, medium and long term adaptations are identified for WSUP (or the local provider), NAIVAWASS and the City Council.
