2. Descripción de la Tecnología MST

2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Use of the SLM technology facilitates the development of bench terraces from contour channels by gradually removing soil material up the slope for an estimated 5 years until the terraces on the slope reach a desired width of 1.2 m.

2.2 Descripción detallada de la Tecnología

Descripción:

The SLM technology is thought to stop water run-off resulting in the prevention of damage to the top soil on steep slopes. This enables better distribution and infiltration of water into the soil. A complementing live fence, along with a metal net along the perimeter aim to stop livestock grazing. Contour ditches are planted in intervals with fruit trees, and the live fence is made of a combination of fire wood, trees and bushes. This combination makes possible the establishment of an agro forestry system on a slope in an area with limited irrigation using making use of the natural rainfall.
Details: 1. Ditches are dug out along the contour lines drawn by an "A" frame on the slope. 2. Seedlings are planted in 5 metre intervals, positioned right in the middle of the ditch. 3. The back wall behind each tree (upslope) has a half moon cutting to enable an even water/moisture supply. 4. The ditches are barriered with "septas" between two trees to trap water in the individual sections. 5. Horizontally across the ditches, the tree species vary, but vertically are homogeneous. 6. The strips between ditches are left free to enable natural grass to grow. 7. The residual soil material is mounted in front of the ditches in piles the width of a shovel. 8. The complementing perimeter live fence and metal net (1.5m height) is supported by wooden poles made of Acacia trees. (Assumed life span of poles is 25 years). 9. Improvised drip irrigation with 5 litre plastic bottles is used together with mulch coverage beneath the trees. 10. Species composition: apple, cherry, apricot, grape, walnut, pomegranate. In the garden; species of Acacia, Ailantus, dogroses and willow act as a live fence.

Purpose of the Technology: The aim of this system is to significantly reduce the water run-off that removes the top soil, and to subsequently prevent water erosion, and the formation/development of gullies. This can be achieved through the following methods; conserving the available resources and using them more efficiently, prevention overgrazing and improving the natural soil cover, as well as changing the type of land management towards a more sustainable and profitable one.

Establishment / maintenance activities and inputs: The plot was established on one side of a micro watershed. In mid February the contour lines were identified using an “A” frame. Digging of contour ditches then took until late February. The material was accumulated down the slope in deposits the width of a shovel to build a riser. At the beginning of March all the fruit tree seedlings were planted in the middle of the ditches. Perimeter fencing was constructed and live fence plants were planted up until late March. In May, the grass around the trees was cut and used for mulching beneath the trees. During June and July in the first year the plants needed watering 3 times a week which was done using a drip irrigation system with 5 litre plastic bottles. To help prevent the water heating and evaporating, the bottles were left under the mulch cover. Mulching and irrigation are repeated every dry and hot season. Every spring, the soil material is removed alongside the inner wall of the ditch just taking an amount that equals the width of a shovel, and accumulated down the slope to extend the riser. Materials required include: (1) Ditches: hand tools, stakes, rope, “A” frame, (2) Live fence: seedlings of Acacia, Ailantus, willow and dog rose, (3) Fencing: metal net, wooden poles, metal wire, (4) Cow dung, lime suspension, straw, mulch, plastic bottles.

Natural / human environment: The watershed can be characterised as follows: Hydrology - surface water is available only at times of rain and snow melt, this can be used for irrigation only. No sources of potable water exist. Soils are of loess type, as generally characteristic to the whole area. Flora - natural grasses prevail in the micro watershed, 9 species could be identified. Natural bushes and trees were completely removed due to high demand for fuelwood. Cultivation of rare tree varieties and household gardening was practiced in advance of the project. Fauna - Wild animals are often still seen such as turtles, lizards and snakes. Farm animals - mixed breeds of cattle, sheep and goats are very important. The households in this micro watershed area own almost 350 animals. The majority of these are kept for the summer season in adjacent pastures. The micro watershed was first inhabited in early 2000. Five households were established with a total of around 40 inhabitants. Family heads tend to be in their early 40s. Families have 7 to 9 members, including 5 to 7 children. All are of Tajik ethnicity, and Muslim, open to secular values. Of these 5 households, only 4 households have adopted the SLM technology. The fifth household only decided to join the project after witnessing their neighbour’s positive experiences. Both spouses tended to be involved in the activities. Both men and women took part in the training sessions and orientation meeting. However, it is likely that most decisions were made by the men, after the women had shared their ideas. Work load: providing the external inputs, construction and the heavy manual labour were done by the men. Maintenance work: watering, mulching and grass cutting was shared between men and women. Digging and fencing were performed in "hashars" - community labour groups. As women spend more time at home working within their households, they tend to perform more maintenance work on the plot compared to men. Other activities away from the farms are important to the family budget providing a means of extra income. This often includes men’s long term migration to Russia to find work.

Comentarios:

Major land use problems (compiler’s opinion): Implementation of land tenure rights at a local level was also a major barrier.

Major land use problems (land users’ perception): There is a soil and water conservation project in place to manage water runoff, soil erosion and gully formation. Low land productivity only allows for wheat production with long fallow periods. Improper pasture management has led to overall overgrazing.

Nomadism: animals taken to summer pastures

Semi-nomadism / pastoralism: animal graze around villages

Ranching: no practice

Cut-and-carry/ zero grazing: almost extinct

Improved pasture: no practice at all

Clear felling of (semi-)natural forests: No selection in times of electricity cuts in winter season.

Forest products and services: timber, fuelwood, fruits and nuts, grazing / browsing, other forest products / uses (honey, medical, etc.), nature conservation / protection

Future (final) land use (after implementation of SLM Technology): Mixed: Mf: Agroforestry

Constraints of infrastructure network (roads, railways, pipe lines, power lines): no irrigation network, heavy transports costs

Comments on adoption trend: Metal for the net was costly- farmers had to convince the project to subsidise prior to adoption, otherwise would reject adopting (area has high risk of crop damage- high livestock density, grazing not controlled).
Year following implementation: 3 farmers in neighbourhood have adopted on own funds; much more are willing to adopt, but need external support
