2. SLM技术的说明
2.1 技术简介
技术定义:
Regeneration of degraded hill side using structural, vegetative & managerial measures.
2.2 技术的详细说明
说明:
Managerial Measures : awareness generation amongst community, users groups, area closure, cut & carry system; Structural Measures :- contour trenches, gully plugs, sunken structure for run off and erosion control; Vegetative Measures :- seeding of grasses and shrubs, plantation of dryland fruit & forest tree species, vegetative barriers across slopes & gullies.
Purpose of the Technology: Short term benefits :- increased fodder availability, increase in well water levels, increased soil moisture in foot hill crop lands; Long term benefits :- environmental regeneration leading to increased production from non-arable & surrounding arable lands.

6.5 技术采用
注释:
15% of land user families have adopted the Technology with external material support
340 land user families have adopted the Technology with external material support
Comments on acceptance with external material support: survey results
There is a little trend towards spontaneous adoption of the Technology
Comments on adoption trend: Elemets of the technology have been adopted by land users eg. SWC, grass improvement. There is tremendous pressure on grass land due to large number of local cattle & goats, migratory herds of camel & sheeps. Hence spontaneous adoption is not observed since community mobilisation is essential as also efforts for user rights.
