It was a low-cost project to retain mudstreams/erosion consequences by the building of a horizontal dyke/dams at the bottom in the valley, which will retain the water longer in the valley, so reducing runoff and sediment transport to the villages downstream. Additionally they changed crop growing from corn to grasslands to help reduce erosion.
