2. Description de la Technologie de GDT

2.1 Courte description de la Technologie

Définition de la Technologie:

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 Description détaillée de la Technologie

Description:

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.

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

Commentaires:

Main causes of degradation: soil management (Tillage on steep slope >35%.), deforestation / removal of natural vegetation (incl. forest fires) (Natural tree and shrubs removed completely.), over-exploitation of vegetation for domestic use, overgrazing (Stocking rates do exceed the standards in multiple times), disturbance of water cycle (infiltration / runoff) (Run-off is induced by maximum removal of vegetation cover.), land tenure (Unclear land right situation induces irresponsible attitudes.), inputs and infrastructure: (roads, markets, distribution of water points, other, …) (Very limited infrastructure development, vital infrastructure points are a long distance away.)

Secondary causes of degradation: Heavy / extreme rainfall (intensity/amounts) (Induces gully formation and mass movement.), droughts (If vegetation is dry then less soil cover is provided.), other natural causes (avalanches, volcanic eruptions, mud flows, highly susceptible natural resources, extreme topography, etc.) specify (The gradient is over 30%.), population pressure (Large family sizes, and high growth rates causes increased need for food and living space in the area.), poverty / wealth (Very limited financial power to develop the land.), labour availability (Though cheap labour is available, it takes much effort to organise communities to work together for SLM activities.), education, access to knowledge and support services (Basic schooling of children, no state provided extension or training after school age.), war and conflicts (The after-effects of recent civil war still have some influence.), governance / institutional (Communist attitudes still persist, very slow institutional development.)

6.5 Adoption de la Technologie

Commentaires:

100% of land user families have adopted the Technology with external material support

4 land user families have adopted the Technology with external material support

Comments on acceptance with external material support: Project subsidised only 50% of material inputs.

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

6.7 Points forts/ avantages/ possibilités de la Technologie

Points forts/ avantages/ possibilités du point de vue de l'exploitant des terres
It helped to acquire more land user rights.
Land users feel they have an increased status in local society.
It has good potential for replication in other areas.

How can they be sustained / enhanced? It would be better if the more expensive parts of the input were subsidised.
Good long term perspectives for improvement of livelihoods.
It allows a positive long term change in household provision regarding food, employment and energy sources, allowing more spare time for cultural events and education.
Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
It made possible the change to more sustainable land management techniques.
The technology is well suited to the sloping landscape and is easy to adopt.
The technology allows the use of locally available materials, and has low maintenance costs.
It fits well to the local needs for land reclamation and conservation, and sits within the legislative frameworks.

How can they be sustained / enhanced? There has been a recent state decree to encourage promotion of orchard development.
It has a positive effect on the areas downstream.

How can they be sustained / enhanced? Prior to implementation of the technology, areas downstream were often were damaged by floods.

6.8 Faiblesses/ inconvénients/ risques de la Technologie et moyens de les surmonter

Faiblesses/ inconvénients/ risques du point de vue de l’exploitant des terres Comment peuvent-ils être surmontés?
It needed some immediate on-site adjustments when structuring the half moon cuttings in the contour ditches. The farmer's opinion should be considered during the adoption of the technology, and to assist with any changes made.
It caused some disagreements between the farmers and the consultant over what part of the material input should be subsidised. The consultant should try to ensure they understand the social and economic factors affecting the locals.
Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé Comment peuvent-ils être surmontés?
Needs more until the final structure is finished This depends on the length and intensity of any precipitation/drought/dry spells etc.
It is a new technology in this area so will need some time to be proven effective.
External knowledge is needed for the establishment and maintainance of the technology.
Extra workers are needed for the complementary drip irrigation - child labour is often used for this.
