2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Catchment treatment of degraded forest land including social fencing, infiltration trenches and enrichment planting with trees and grasses for production and dam protection.

2.2 Detailed description of the Technology

Description:

Forest catchment treatment aims to achieve production and environmental benefits through a combination of structural, vegetative and management measures in badly degraded catchments above villages. These efforts are concentrated in the highly erodible Shiwalik Hills at the foot of the Himalayan range where soil erosion has ravaged the landscape, and the original forest has almost disappeared.
The purpose of forest catchment treatment is first to rehabilitate the forest through protection of the area by ‘social fencing’ (villagers agreeing amongst themselves to exclude livestock without using physical barriers), then construction of soil conservation measures (staggered contour trenches, check dams, graded stabilisation channels etc; see establishment activities), and ‘enrichment planting’ of trees and grasses within the existing forest stand to improve composition and cover. These species usually include trees such as Acacia catechu and Dalbergia sissoo, and fodder grasses - as well as bhabbar grass (Eulaliopsis binata), which is used for rope making. The combined measures are aimed at reestablishing the forest canopy, understorey and floor, thereby restoring the forest ecosystem together with its functions and services. Biodiversity is simultaneously enhanced.
The second main objective is to provide supplementary irrigation water to the village below through construction of one, or more, earth dams. The village community - organised into a Hill Resource Management Society - is the source of highly subsidised labour for forest catchment treatment. After catchment protection around the proposed dam site(s), the dam(s) and pipeline(s) are constructed. The dams are generally between 20,000 and 200,000 m3 in capacity, and the pipelines usually one kilometre or less in length.
Apart from irrigation, the villagers benefit from communal use of non-timber forest resources. Forest catchment treatment (associated with the approach termed ‘joint forest management’ - JFM) has been developed from a pilot initiative in Sukhomajri village in 1976, and has spread very widely throughout India. This description focuses on Ambala and Yamunanagar Districts in Haryana State.

The Shiwalik hills where the SWC technology was applied is one of the eight most degraded, rainfed agro-ecosystems of India. It is highly erodible, with presence of low water retentive soils and severe soil erosion, haing water scarcity despite average 1000 mm annual rainfall.

  • Silvo-pastoralism

Grazing land

Forest/ woodlands

  • Rehabilitated natural forest
Type of tree:
  • Acacia species
  • Dalbergia sissoo
Comments:

Major land use problems (compiler’s opinion): The Shiwalik Hills are extremely prone to both surface erosion and landslides, and general degradation of vegetation due to over-exploitation. Some areas have become completely denuded because of overgrazing and woodcutting. Furthermore there is no, or inadequate, water for irrigation of crops.

Grazingland comments: Due to free grazing, much of the forest land was becoming barren and fodder yield declined over a period of time. The average fodder yield was about two quintals/ha of forest land and fodder consumption was 26.69kg/animal/day.

Problems / comments regarding forest use: Tree species like Khaci (Acacia catechu), Dalbergio sissoo in pits and slips of bhabbar grass (Eulaliopsis binata) on mounds of trenches and hill slopes were planted. Bhabbar grass was sold out by forest department to contractors.

Type of grazing system comments: Due to free grazing, much of the forest land was becoming barren and fodder yield declined over a period of time. The average fodder yield was about two quintals/ha of forest land and fodder consumption was 26.69kg/animal/day.

Secondary types of degradation addressed: Wg: gully erosion / gullying, Wm: mass movements / landslides, Ha: aridification

Main causes of degradation: deforestation / removal of natural vegetation (incl. forest fires), education, access to knowledge and support services (Absence of institutional arrangements to disseminate the knowledge from lab to land and involve the users in implementation)

Secondary causes of degradation: overgrazing (Subsistence economy, dependance on forests for fuelwood and fodder, livestock were low quality, free grazing type. And these were no regulatory mechanisms to share usufruct from forests with people.), poverty / wealth (Lack of capital at the grassroot to take the initiative by the farmers themselves)

Comments:

This information is indicative and is based on calculations derived from Thaska village (Yamunanagar District)
where there are 3 dams - collecting the runoff from the total forest catchment of 75 ha. The cost range of treatments per
hectare of rehabilitated forest is generally US$ 200–700 (where the main cost is that of the dam construction) and typically the area of supplementary irrigation (command area) is twice as large as the forest catchment treated (in this case the irrigated area is 150 ha).
Cost per unit: the treatment of a 25 ha unit of catchment including construction of a dam costs around US$ 10,000.
