Description of the SLM Technology

Short description of the Technology

Development of micro-catchment for soil and water conservation and for the provision of supplementary irrigation during the dry season.

Detailed description of the Technology

Small Water Impounding Project (SWIP) is a water harvesting and storage structure consisting of an earth embankment spillway, outlet works and canal facilities. It is designed for soil and water conservation and flood control by holding as much water as possible during the rainy season. The reduced volume and force of runoff subsequently reduced their eroding power of water thereby minimizing soil erosion and silting of fertile bottom lands. The reservoir with its stored water is an important supplemental source of water for agriculture and is also used for fisheries. SWIP development involves a holistic approach. The watershed is developed for land use that enhances water infiltration and minimizes soil erosion (for the long life of the reservoir). The most common use of the watershed is agro-forestry. The service area is used for high value crops that minimizes the use of water on a controlled basis. A holistic and integrated approach is done in managing the micro-watershed. The farmer-beneficiaries of the irrigation water and those of the watershed are organized into an association. They maintain the system and protect the watershed by advocating sustainable agriculture.
