Earth dams: A simple way to save lives
When rainfall ceases for long periods of time, earth dams are life-saving. They bridge the gap between rainy seasons and ensure people can easily access water for drinking, washing and farming.
Earth dams are simple and cost-effective, and allow people to harvest water nearer their homes. They are built up by compacting successive layers of earth (soil, silt, gravel and rock) in a large site.
This site acts as a sort of reservoir. The rain water collected is safely stored there, then piped from the site to a community water point.
An effective way to build resilience against climate change. The dams make sure that when it does rain, the water will be conserved and used as best it can. They increase the amount of water available to people and the length of time it is available, leading to more stable income for farmers and ensuring there is more food harvested.
