6. Impacts and concluding statements
6.4 Cost-benefit analysis
How do the benefits compare with the establishment costs (from land users’ perspective)?
How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
6.5 Adoption of the Technology
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.
