Description of the SLM Technology
Short description of the Technology
Controlling a small watershed comprehensively with structural, vegetative, management, and agronomic measures based on harvesting area of ground water and underground water, to improve the production and conservation of land.
Detailed description of the Technology
Over several decades of SWC practices, a successful experience of SWC has been concluded, that is Small Watershed Comprehensive Development. The main aim is regarded a small watershed as a control unit for soil and water conservation. The approach is to control soil and water loss comprehensively by structural measure combining vegetative, agronomic and management measures. Specifically:
1. Agronomic method/measure: contour cultivation, area closure, and green manure
2. Vegetative method/measure: plant trees, grass, grass strip, windbreaks and reforestation
3. Structural method/measures: terrace, ands, small reservoir, and dams
4. Land use management/measure: grazing, area closure, and land use change
