2.1 Short description of the Technology

Definition of the Technology:

Regeneration of degraded hill side using structural, vegetative & managerial measures.

2.2 Detailed description of the Technology

Description:

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.

4.2 General information regarding the calculation of inputs and costs

other/ national currency (specify):

Rupees

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

48.85

4.3 Establishment activities

4.4 Costs and inputs needed for establishment

Comments:

Duration of establishment phase: 24 month(s)

4.5 Maintenance/ recurrent activities

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

The treatment covered an area of aroung 10 ha. 1- Contour Trenches - 6000 Rmt. 2- Large Boulder Check - 58 3- Small Boulder Check - 55 4- Dugout - 1 No. 5- Doh - 1 No. Seeding with jatropha, stylo and dinanath. Planting of saplings.

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

1- Slope : - Due to steep slope , interval between contour trench lines was less; 2- Soil Depth : - Due to stony strata, excavation cost was high; 3- Material : - Boulders were transported from outside. 4- Lead/Lift : - Due to steep slope, labour output was less 5- Drought :- Replantation costs were high

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

Comments:

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.
