Purpose of the Technology: the technology serves the folowing purposes 1. Short and long term economic benefits to land owners 2. Employment generation leading to reduced migration 3. Conservation of soil and water through vegetative and mechanical measures.

Establishment / maintenance activities and inputs: 1. Community organisation, formation of Village Development Association, Identification and training of beneficiaries 2. Delineation of micro-watersheds and plantation blocks. 3. Establishment of farmers's nurseries 4. Land preparation, sinking bore-well, plantation and inter-cropping 5. Watch and ward.

Natural / human environment: The environment is semi-arid, drought prone and subject to wind erosion. Soil depth is good.

注释:

Total area covered by the SLM Technology is 3.83 km2.

The area is predominantly degraded land affected by wind erosion. The annual rainfall is <600 mm, however distribution is erratic resulting in drought conditions. People are mostly small farmers engaged in rainfed agriculture, however large areas have been abandoned due to frequent crop failure. The technology has been applied in a gross area of over 300 sq.km.

Major land use problems (compiler’s opinion): Uncontrolled grazing on un-cultivated lands, abandonment of fields by poor farmers due to recurrent crop failure as a result of drought.

Major land use problems (land users’ perception): Crop lands are not economocal to cultivate due to recurrent crop failure as a result of drought. This has lead to abandonment of fields and increase in numbers of small livestock which are left free to graze.

Type of cropping system and major crops comments: The area is single cropped and hence only one food crop is taken per year.
