Description of practice
Micro-basins are formed by constructing a ridge around a cultivated area. They are highly efficient at storing water although any excess water cannot run off.
|Examples of how to use micro-basins
(see Note below)
In the Vallerani system a special tractor-pulled plough constructs micro-catchments combining traditional techniques of rainwater harvesting with mechanization for large scale land rehabilitation.
Negarims are V-shaped micro basins particularly constructed for fruit tree production in water-scarce areas. The tree is planted in the downstream corner of the basin, the rest of which serves as the catchment area.
Water harvesting basins
1 m wide basins with a 2 m wide runoff area are constructed. The basins are mulched with either straw or stones. The runoff area is left bare and untilled to encourage development of a crust over which water runs into the basin.
