2.1 Descrição curta da tecnologia

Definição da tecnologia:

Rehabilitation measures, including eyebrow pits and live fencing, were implemented on degraded communal grazing land to
reestablish a protective vegetative cover

2.2 Descrição detalhada da tecnologia

Descrição:

An area of heavily degraded grazing land was rehabilitated by establishing eyebrow pits to control and harvest runoff, planting trees and grasses, and fencing the site to control grazing. The main purpose was to re-establish vegetative cover on the almost bare, overgrazed site. The site is community land of the 40 households (240 people) of Dhotra village in the Jhikhu Khola watershed. These people are very dependent on this area due to the lack of alternative grazing sites. The rehabilitation site is surrounded by irrigated cropland downstream, grazing land, and degraded sal (Shorea robusta) dominated forest. Rainfed forward-sloping terraces immediately adjoin the site.
About 130 eyebrow pits were dug, together with catch drainage trenches. Several species of grass and fodder were planted along the ridges of the eyebrows and drainage trenches. Contour hedgerows were established between the eyebrow pits and trenches, and trees were planted just below the pits. The maintenance is quite easy: the vegetation needs to be cut back from time to time and the pits cleaned before the pre-monsoon period. The remaining bare areas should be revisited each year and replanted.
The area has a distinct dry season from November to May and a wet monsoon period from June to October. Annual rainfall is around 1200 mm. The site has red soils that are highly weathered and, if not properly managed, are very susceptible to erosion.

Comentários (tipos de projeto, etc.):

The hedgerow technology came from the Philliphines, modified from the SALT (Sloping agriculture land technology) technology. The eye brow pit technology was implemented by the Department of Soil Conservation and Watershed Management in Nepal and was adapted from them. Villagers approached the People and Resource Dynamics Project (PARDYP) for advice. PARDYP assisted, based on experiences made before with rehabilitation experiments under similar conditions. Mainly developed according to theoretical and site specific knowledge.

3.1 Principal/principais finalidade(s) da tecnologia

• Reduz, previne, recupera a degradação do solo

3.2 Tipo(s) atualizado(s) de uso da terra onde a tecnologia foi aplicada

Comentários:

Major land use problems (compiler’s opinion): The major land use problem is the small per capita landholding size for cropping. These holdings are mostly rainfed, have a low soil fertility status and acidity problems, and are susceptible to erosion. Intense rainfall at the beginning of the rainy season causes considerable soil loss (rill and gully erosion).

Major land use problems (land users’ perception): Overgrazing leading to lack of vegetation.

Ranching: Yes

Future (final) land use (after implementation of SLM Technology): Forests / woodlands: Fp: Plantations, afforestations

Caso o uso da terra tenha mudado devido a implementação da tecnologia, indique seu uso anterior à implementação da tecnologia:
