2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Stones cleared from land within a narrow valley floor where flat land is at a premium, was used to construct a perimeter stone wall which was subsequently supplemented with a row of poplar tree to protect an agro-forestry area with small scale supplementary irrigation.

2.2 Detailed description of the Technology

Description:

The area in question is a very narrow, flat valley floor, 95% of which was covered in stones and boulders, and devoid of vegetation, both grass and trees/shrubs. The stones in the area were cleared and used to build a protecting, perimeter wall (approx. 1.5 m high). This was then supplemented by an inner row of fast growing poplar trees. The stone clearing has resulted in deeper soil within the protected area that has led to far greater vegetation coverage, such as grass (that can be cut and used as fodder), forest and orchard trees and vegetable gardens. Irrigation was provided to the area by a small diameter poly pipe from a permanent spring. The area is now being extended to almost double the size of the initial walled agro-forest area.

Purpose of the Technology: The farmer’s primary aim, in initiating and continuing this SLM approach, was to “leave a legacy of improved land” for future generations, recognising how little flat and potentially productive land there is in this high, narrow valley location. Clearing the land of stones and building a walled enclosure that was irrigated greatly assured the quantity and quality of fodder for his animals, as they remain fenced in beside his village home almost all year. Fruit and vegetable production was also greatly improved.

Establishment / maintenance activities and inputs: The family commenced stone clearing and wall construction in 2005. The next task was tree planting; poplar trees were planted around the wall's perimeter. The irrigation source was tapped into using a poly pipe. The vegetable gardens are seasonal and their plants change with the seasons and the family’s needs. Stone removal continues even now, to improve the soil in the walled area. The farmer hopes to extend the walled area in the future.

Natural / human environment: Before the family began clearing stones and building the wall, this land had almost zero productivity. This area has a shortage of cultivated land and with increases in popluation and continued food insecurity, cultivated land is at a premium.

Comments:

Major land use problems (compiler’s opinion): This area is strongly dependent on the extremely limited flat, valley bottom land for the production of pasture, 'cut and carry' fodder, orchards and vegetable production. 95% of this land is covered in stones that require removal before any productive capacity can be achieved. Even when cleared of stones the soil is still very shallow (< 20cm) and requires irrigation to ensure plants survive the hot summer months

Major land use problems (land users’ perception): Same – the above words were used by him in the on-farm interview

Cut-and-carry/ zero grazing: sheep/cattle

Plantation forestry: The Poplar trees they planted are pruned and thinned for firewood and construction materials

Other type of forest: orchard species: Apple, Apricot, Cherry

Forest products and services: timber, fuelwood, fruits and nuts

Future (final) land use (after implementation of SLM Technology): Grazing land: Gi: Intensive grazing/ fodder production

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

The human labour costs involving the family were nothing as they willingly gave of their time to clear the land and build the wall, plant trees and create vegetable gardens. The real labour cost were the few days when the farmer paid 3 men to help build the wall.
The cost of the wall cost was also nothing as all materials came from on site.
Trees – there was an initial start up cost and the farmer said he tries to plant at least 20 new trees each year to maintain and enhance productivity
Grasses (fodder) – are self regenerating and local. The farmer has never bought grass seed or used fertiliser on the grass

  • poor
Individuals or groups:
  • individual/ household

Gender:
  • men
Indicate other relevant characteristics of the land users:

Land users applying the Technology are mainly common / average land users

Difference in the involvement of women and men: Not a large difference. The farmer’s wife shares the workload but tends to focus more on the garden, fruit production, household duties and bee keeping. The farmer conducts hay cutting and gathering, stone removal, fence upkeep and animal tending (feeding and slaughtering when required).

Population density: < 10 persons/km2

Annual population growth: 1% - 2%

100% of the land users are poor.

Off-farm income specification: The issue is that the older and the very young family members (ie the farmer and his wife are in their late 50s ) stay on the farm. The rest (18 to 50 yrs ) have paid employment in Dushanbe and Russia, and only visit the farm, occasionally. However, it is believed they part-finance (contribute) to the upkeep of the family farm.

Market orientation of production system: All of the farm produce stays on the farm for home consumption, but they do eat well and very healthy (fresh and organic) food. Their cattle are also well fed and healthy .

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 91-100%
Comments:

100% of land user families have adopted the Technology without any external material suppor

Comments on spontaneous adoption: Unsure how many such walled agro-forests are in this region. Would need to consult with Jamoat leader. There are quite a few walled areas. But unsure about the number and content (ie technologies inside).

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: There seem to be quite a few enclosures in this area – but we have not conducted a formal survey.

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
As above, as these words were transcribed during the farmer interview, on site.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
The stone clearing and wall building underpins the whole SLM initiative. That it was achieved by only 3 or 4 people, in under a year and at such a low cost (with minimal paid labour) adds to the strengths. The wall is also critical to keep animals out of this now richly vegetated area, not only sheep and goats but also wild pigs and even wolves. The stone clearing “created” soil which is critical for all the vegetation growth within the walled area.

How can they be sustained / enhanced? The farmer is in the process of expanding the stone cleared area, and is using the stone to build a larger perimeter fence, aiming for a larger plot of 2 or 3 ha.
Bringing water to the site (at his own cost) by poly pipe was a critical part to the technology. The walled agro-forestry area would have struggled without this extra and constant water supply – as the soil is so shallow (all the rock remains below the soil surface). Now he can have good fodder grass, trees, orchard and vegetables with a guarenteed regular supply. Getting the plants and trees through the hot summer months is the key use of the water.

How can they be sustained / enhanced? The farmer wishes to source a 2nd spring to water the extended (2 - 3 ha) site.
The rich mix of vegetation on the site (trees, perennial grasses and vegetable production) not only ensures the intervention remains viable but also ensures a continuous, rich, healthy food supply to the family and their animals year round.

How can they be sustained / enhanced? The farmer has already started to plant new fruit trees outside the original walled area, in readiness for moving the fence to encompass a 2 -3 ha site.

6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
As above; as these were the sentiments of the farmer during the on site interview.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
None really. What the farmer has achieved is most impressive. Particularly as his Technologies were all self-financed and conducted slowly and carefully, hence with no financial burden to the family and no interruption or lessening of their food supply. If costs / budget permit (unlikely) to bring some power-type assistance to stone removal (like a small tractor) or a solar powered pump to increase irrigation water pressure. However, the farmer may not wish to be reliant on such items, as if they breakdown, his whole enterprise (currently so successful) may suffer.
