Section 1. Contexte de la meilleure pratique : conditions du cadre (environnement naturel et humain)

Brève description de la meilleure pratique

Pani-kholsi is a degraded micro-catchment of foot hills of the Chure region.  Due to loss of vegetation and fragile geological condition of the catchment a huge quantity of soil were being eroded to the downstream annually. The settlements in the upstream were highly vulnerable due to gully and landslides and downstream communities were vulnerable by flash flood, river/stream bed rising, and sedimentation, that affected the agricultural land, settlement and infrastructure. Most of cultivated land areas along the river/stream were converted to the unproductive and sandy area due to stream bank cutting and debris deposition by the stream.
The District Soil Conservation Office under the Department of Soil Conservation and Watershed Management in partnership with local community has designed the technology for the rehabilitation of land since 1995. The activities implemented were;
•Series of gabion and dry-stone check dams construction in highly risky area
•Contour ditches and trenches all over the degraded area
•Forest and fruit tree plantation based on the site condition
•Bamboo, Fodder and grass plantation.
•Bamboo shaft witling and cutting plantation  
•Construction of proper and safe drainage system
•Thinning and pruning in time to time
•A watch man for the take care of conservation works
After 10 years of rehabilitation works, the area of micro-catchment became protected and more than 1000 households of upstream and down-stream of this catchment were saved from the hazard of landslides, gully and flash floods. Presently the user group are actively managing the catchment and utilizing the forest products systematic manner.

Site

Panikholsi, Bardibans VDC-4, Mahottari District, Nepal

Brève description de l’environnement naturel du site

Sub tropical climate with maximum temperature is 370C and minimum temperature is 2.60C and average annual rainfall nearby this location is 1841.1 mm
Chure hill is formed by the classic fluvial and terrestrial sedimentary rocks and varies from clay stone, sandstone to conglomerates with the soils of sandy-clay, silts and pebbles. The geological units of Pani kholsi Micro-catchment is falls under the middle Siwalik.
Located in the bottom of Chure hills with the slopes of 10-20 percent. Panikholsi micro-catchment is directed to south west aspect with the altitude ranges from 410 - 500 meter from mean sea level.

Conditions socio-économiques dominantes des personnes vivant sur ou à proximité du site

The income level of this community is below the national average due to traditional rain fed agricultural practices and subsistence livestock farming.
The total number of household in this Pani-kholsi micro-catchment is 415 and average size of the family is 6 people per family with a total population of 2492 (Census 2001). The main occupations of these families are agriculture and only few do business as shop keeper. The literacy rate of the residents is only 66 percent. Presently the secondar
An average land holding of each family is 0.5ha, with the private ownerships and land use right.  
Agriculture is the main sources of income for the majority of farmers in this micro-catchment area. Except the agriculture, they are getting the income from cash crops i.e. vegetable, fruits and forest product.

Sur la base de quel critère/indicateur(s) (sans relation avec la stratégie) la pratique proposée et technologie correspondante ont-elles été considérées comme « meilleures »?

Panikholsi micro-catchment rehabilitation is a best practice for the degraded catchment rehabilitation because it rehabilitated the land and converted highly degraded land into the dense forest within the period of 12 years. This best practice also created oncome for local community by selling forest products and livestock raising due to increased biomass production. At the same time, the level of confidence on technology and the level of awareness on people have been increased for the replication of technology in the locality.

Section 2. Problèmes abordés (causes directes et indirectes) et objectifs de la meilleure pratique

Principaux problèmes abordés par la meilleure pratique

Rehabilitation of degraded land through micro-catchment treatment activities

Décrivez les principaux problèmes liés à la dégradation des terres abordés par la meilleure pratique

The catchment of more than 300 hectares of sloppy land was degraded due to removal of vegetation that accelerated soil erosion, gulling and landslides. Deforestation happened due to uncontrolled cutting of forest. The lands of this catchment became unproductive and the settlements around the catchment and downstream became highly vulnerable due to the risks of landslides, gullies, stream bank cutting, flood and sedimentation.
After implementation of the program of micro-catchment rehabilitation, this area is reclaimed and controlled the soil loss and river bed rising, flooding to the settlements and cultivated lands and created an income generation opportunities to the local community.

Précisez les objectifs de la meilleure pratique

The main objectives of best practices are;
1.Rehabilitation of degraded land.
2.Control of landslides, gully and stream bank cutting, and degraded land rehabilitation,
3.Reduce soil loss from degraded land and reduce sedimentation in river and reduce incidence of flooding to the settlements.
4.Creation of opportunity for the income generation for the local people.  

Section 3. Activités

Brève description des principales activités, par objectif

Rehabilitation of catchment by applying different techniques like landslides treatment, gully control through check dam, stream bank protection,

Impact sur la biodiversité et le changement climatique

Décrivez:

This best practice is very much compatible to lower down gthe impact of climate change in the local level mainly through increased biomass from grass and tree plantation, conservation of productive soil and reducing the risk of flood, sedimentation and damage of agricultural land and infrastructure protection in the downstream area. Other positive impact is increased agriculture production that secures food security of local people. Planting of fodder, grass, tree species and fruit in the community land and vegetable and cash crops are farming reduce farmers vulnerability to climate change impact.
