Establishing fences from stone walls and poplar trees around the perimeter of fields

Author: Knowledge Management in CACILM Phase II, ICARDA.

Definition of technology:

The site located at a foot of a narrow valley was cleared of stones, protected by a stone wall along the perimeter and surrounded with poplars for protection of a site.

Brief summary of technology:

The site full of stones was originally deprived of vegetation.

Cleaning of stones provided possibility to grow annual vegetable crops, grass and tree species. Irrigation was provided from a constant spring by means of a polyethylene pipe of small diameter.

A protective wall was built from the stones of the site along a perimeter of ca. 1.5 m height. Then this protection was enhanced by an internal strip from fast-growing poplars.

Cleaning of stones and creation of a wall strengthen an initiative of sustainable land management. The wall is important means of protection against animals which can come into this rich vegetative site (not only sheep, goats, but also wild boars). Cleaning of stones "creates" the soil which is very important for vegetation.

Currently, the site is expanded practically twice and covers 2-3 ha. Though the technology was financed by the dekhkan himself, and carried out slowly and carefully, it therefore did not render notable financial burden to the household. Stone wall was constructed by 3-4 workers during a year for a low payment.

Location: Kushon, Romit, Vakhdat, Central district of Tajikistan.

Area of technology application: 2 ha.

Stage of intervention: rehabilitation / improvement of bare land.

Main land use issues and the main causes of land degradation:

95 % of the land are covered with stones, and without their removal it is impossible to be engaged in agriculture.

Even after cleaning of stones the soil layer remains small (

Main technical features of technology:

Improvement of soil cover, structure of the top soil layer, increase of infiltration and water preservation in the soil, increase of biomass.

Type of land use Conservation measures

Non-used land.

very stony pastures (before); land/production of forages, fruit-trees, construction wood and fruit (after).

Agronomic measures:

A1: Vegetation / soil cover.

Vegetation measures:

В1: Covered by trees and bushes.

Structural measures:

С9: Other – cleaning of stones.

Management measures:

У1: Change of land use type ;

У2: Change of management/level of intensity

Environment

Habitat

Average annual rainfall: 250-500 mm.

Altitude (meter above sea level): 1000-1500 m.

Landscape: intermountain valley.

Slope (%):30-60% (abrupt).

Soil fertility: low.

Humus content in arable horizon: <1% (low).

Natural soil drainage/infiltration: low.

Anthropogenic environment

Size of land area (ha): 2 ha.

Landholder: small scale.

Land ownership: state.

Water use rights: -

Market orientation: subsistence farming (self sufficiency), free market.

Assessment

Impact of technology

Main advantages:

A variety of crops on a site (trees, perennial grass and vegetables) guarantees a stable provision of a family and a livestock with food and forage all year round.

Main disadvantages:

Very hard and laborious work on cleaning of stones and wall construction.

Acceptance/adoption of technology: There is a small tendency of spontaneous acceptance of technology. There are several fenced sites in the region.
