2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The stabilization of shifting sands by installing means of mechanical protection and planting shrubs around settlements in the Central Karakum

2.2 Detailed description of the Technology

Description:

As a result of overgrazing, the pastures surrounding Bokurdok village have been transformed into bare sand dunes which now threaten infrastructure. Families are forced to spend up to 25% of the family savings for the construction of new houses.
This problem was solved using the technology of sand dune stabilization which includes the installation of mechanical sand dune fixation devices (MSDFs) and planting vegetation adapted to desert environments. MSDFs were made using bundles of reed (of 1-1.2m length), which widely grows along the channel banks. The bundles, 0.02-0.03m in diameter, were bent in the middle (0.5m) and placed vertically into the sand in 25-30cm depth. In this way they are used to establish quadratic parcels with typically 25cm high sidewalls. The optimum grid size is 2x2m and depends on local wind and sand transport conditions. 2x2m MSDFs are used when winds of different directions dominate, otherwise MSDFs are set formed by rows perpendicular to the predominant sand transport direction
The MSDFs assure sand dune stabilization for 2 years. In subsequent years, the stabilization of the sandy surface is achieved by planting seedlings of local desert trees and shrubs and their natural reproduction. 3500-4000 seedlings per ha should be planted if the dunes are to be successfully stabilized without irrigation. If the plants are watered three times in the first season, then the standard for seedling planting is 1200-1300 plants per ha. The planting scheme is as follows: the distance between the plants in the row is 2m, and the spacing between the rows is 4m. Plants are planted 20-40cm deep after the sand has been soaked by rainfall in January-February once temperatures are above 0 ºC

Purpose of the Technology: The purpose of this technology is to improve environmental conditions and the sustainability of farms in the village in general. This can only be achieved if vegetation on degraded pastures near the village is restored and infrastructure is protected against the advance of the desert

Establishment / maintenance activities and inputs: The GTZ project “Participatory management of natural resources in 3 biogeographic regions of Turkmenistan” has provided funds for activities aimed at stabilizing sands in the Bukordak village. 7 families from the village have been involved in the work to stabilize 7 ha of sand dunes. In 2008-2010, within the framework of the CACILM project these activities have been continued. Currently, 50 ha of previously mobile sand dunes, which were threatening the hospital, the main road and houses, have been stabilized

Natural / human environment: The Bokurdak village is located 90 km north of Ashgabad in the Central Karakum Desert. The population is 4,200 people. The village’s water supply for irrigation and livestock is piped from the Karakum Canal. The plants grow on the stabilized sands: Haloxylon persicum, Calligonum sp, Salsola richter, Astragalus sp, Carex physodes perennial grass, and spring annuals. Annual precipitation is around 141mm. Maximum and minimum air temperatures are +47ºC (July) and -28 ºC (January)

3.2 Current land use type(s) where the Technology is applied

Grazing land

Grazing land

Extensive grazing land:
  • Nomadism
  • Semi-nomadism/ pastoralism
Forest/ woodlands

Forest/ woodlands

Comments:

Major land use problems (compiler’s opinion): The pastures' capacity is too low to provide enough forage for livestock grazing. The plants in desert forests are also used as forage and cutting them to satisfy fuel needs reduces the productivity of pastures. The sharp fluctuations in yields on pastures from year to year and from season to season determine the number of animals on farms. Lack of finance, commitment (pastures are state owned) and the necessary knowledge for the rehabilitation of village pastures on sand dunes among the local communities also have an impact

Major land use problems (land users’ perception): Scarce pasture lands and water for watering the animals, especially in dry years, when the salt concentration in well water increases

Nomadism: One or several families live year-round deep in the desert and care for the livestock, but they also have houses in the village

Semi-nomadism / pastoralism: 2-3 farmers take turns grazing animals around a well deep in the desert. However, they are not additionally engaged in land cultivation

Grazingland comments: Farmers of the “Karakum” Daikhan Association are engaged in livestock breeding. Sheep and camels grazed year-round on pastures around wells in the Central Karakum desert

Future (final) land use (after implementation of SLM Technology): Grazing land: Ge: Extensive grazing land

Type of grazing system comments: Farmers of the “Karakum” Daikhan Association are engaged in livestock breeding. Sheep and camels grazed year-round on pastures around wells in the Central Karakum desert

Vertical mechanical sand dune fixation means generally a stabilization of moving sands for two years (as long as the mechanical sand dune fixation can persist). Stabilization of the sandy surface in the following years is achieved by planting seedlings of local psammophytic plants (Haloxylon persicum, several species of Calligonum sp., Salsola richter, S. paletzkiana) and their further self-restoration. It is identified that in order to successfully stabilize the sandy surface (without irrigation) about 3500-4000 pieces of seedlings per 1 ha should be planted, but often we faced low level of plant rooting. When irrigation is carried out three times (60 l per plant in the summer), the ratio for seedlings planted was 1200-1300 plants per 1 ha (80-95% survival rate of plants). According to the planting scheme a distance between the plants was 2 m and 4 m between the rows. They are planted after the sand is soaked with rainfall to a depth of 30-40 cm and when the air temperatures are positive (January-February)

Comments:

Secondary types of degradation addressed: Bc: reduction of vegetation cover, Bh: loss of habitats, Bq: quantity / biomass decline, Bs: quality and species composition /diversity decline, Bl: loss of soil life

Main causes of degradation: overgrazing (Unsustainable grazing leads to the destruction of undergrowth and a reduction in the number of edible species, constraining the sustainable development of plant communities), droughts (Drought leads to reduced productivity of pasture vegetation), governance / institutional (A lack of both awareness raising measures and control by the authorities responsible for plant resources has led to their complete destruction (deforestation) in the vicinity of settlements)

Secondary causes of degradation: deforestation / removal of natural vegetation (incl. forest fires) (Lack of awareness raising measures and lack of control by the authorities responsible for plant resources has led to their complete destruction (deforestation) in the vicinity of settlements), over-exploitation of vegetation for domestic use (Cutting shrubs for fuel and building materials leads to a change in climate and to further reduction and changes in the species composition in the associated herbaceous vegetation), change in temperature (Increased temperature in the desert vegetation’s growing season leads to a decrease in the productivity of pasture vegetation), wind storms / dust storms (Dust storms carry sand from the dunes devoid of vegetation, which leads to its accumulation in other places (in households, roads, economic facilities, etc.)), population pressure (Overgrazing changes the plant species composition and reduces the land's productivity. Cutting the shrubs changes wind patterns in the plant communities and reduces the number of herbaceous vegetation)

The costs were calculated for mechanical stabilization of 1 ha of moving sand dunes by installing cells of mechanical san dune fixation made of reed (200m³/ha) and planting the sand stabilizing shrubs – 1250 pcs/ha

4.8 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

There is no special machinery for reed harvesting and packing. Therefore, only manual labor is used. The cost of transporting building materials depends on the type of transport needed and the distance to the place of harvesting. Only one leskhoz (state forestry enterprise) cultivates psammophytic plants, therefore they are expensive

Population density: < 10 persons/km2

Annual population growth: 2% - 3%

100% of the land users are average wealthy.

Off-farm income specification: 10-20% of the Daikhan Association’s members work outside the DA, they bring about 30-50% of the money coming into the family budget

Market orientation of production system: Also Daikhan association, which is a state-owned livestock farm in the Central Karakum. Only arable land on some household plots is cultivated. The village is supplied with water from a 90 km water pipe. A private farm is able to provide for its own needs and can carry out commercial sales.

The area where the work on sand stabilization has been carried out is located on the former pasture lands in the vicinity of Bokurdak village, the administrative center of the “Karakum” Daikhan Association (DA). All animals of the DA are grazed on desert pastures year-round. State-owned animals, 25,090 sheep and 2,329 camels, are grazed at the Daikhan Association’s land. Along with the state-owned cattle, there are private cattle grazed on this land. There are 63,863 privately-owned sheep and 5,909 privately-owned. Currently, there are a total of 88 953 sheep and 8238 camels grazing on the DA’s land. The total area of the DA’s pastures is 845 531 ha. All pastures are owned by the state. The state-owned livestock is leased by farmers. Usually, 1 or 2 farmers get a pasture plot and a well within the boundaries of DA with the leased animals. Farmers do not pay for pastures and wells. The administration of the DA pays the farmers for livestock management by giving them 50% of the total offspring in the herd. If the water in a well is not too salty the animals graze year-round on the pasture. If the water in a well is very salty farmers graze animals only in winter and spring, and they drive cattle closer to the wells with less mineralized water. All farmers have houses in the villages. Each private household has a certain pasture plot (which is not legally assigned to them) and there they graze on average 150-250 sheep and 5-7 camels. Privately-owned cattle is grazed on the pastures around the villages and in the areas around wells, from which the state-owned animals moved to the summer and autumn pastures, and also on unwatered pastures with no wells. For this purpose, each farmer has a vehicle (water carrier) to bring water to the herd. The government does not limit the number of animals owned by farmers. Taxes on animals and fees for pastures are not collected.

6.4 Cost-benefit analysis

How do the benefits compare with the establishment costs (from land users’ perspective)?
Short-term returns:

positive

Long-term returns:

very positive

How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:

positive

Long-term returns:

very positive

Comments:

In the short term, shifting of sand dunes to farms has been ceased. In the long term, the pasture vegetation has grown on barkhans and is already able to recover. When properly used, the vegetation can serve for many years.

6.5 Adoption of the Technology

  • more than 50%
If available, quantify (no. of households and/ or area covered):

10 households covering 100 percent of stated area

Of all those who have adopted the Technology, how many have did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 0-10%
Comments:

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

Comments on acceptance with external material support: Not only 10 families in the immediate vicinity of the area threatened by sand dunes have benefited from the measures implemented, but also the farms located in 200-300 m from the site, as well as the hospital with its outbuildings

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: Implementation of the technology is expensive; therefore people jointly apply it in desperate cases, for example, to protect their own houses in the outskirts of settlements, schools, hospitals, roads between settlements

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Barkhan sands do not come close to the houses and backyards

How can they be sustained / enhanced? We protect our territory. If we would receive assistance from the state, we could extend the territory, because it has a positive effect not only on our house, but on the whole village
Today, the road that runs along the site from the village to our houses is not covered with sand

How can they be sustained / enhanced? At the moment, the young families took plots for home construction along the plantations, where the road passes, since this area is safe from the sand. They limit the grazing of animals themselves
We graze 3 to 5 sheep at the site for our own needs; they are taken from the pastures located deep in the desert

How can they be sustained / enhanced? I do my best to prevent sheep from hindering the self-restoration of vegetation, and think of opportunities to expand my territory
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Using this technology on exposed sand dunes in the immediate vicinity of the household creates sites usable as pastures

How can they be sustained / enhanced? Incredible as it may seem, but if the sites located on the sand dunes near the households would be handed over to the farmers for their personal use, they would learn the above described technology by themselves, but for this we need a law on pastures, that would specify the approach to degraded pastures
In 2-3 years, the vegetation planted on the sand dunes could be used for harvesting the seeds

How can they be sustained / enhanced? It will also enable farmers to harvest the seeds on their plots and sell them to interested organizations. But we should remember that the seeds are often eaten by animals and this complicates their harvesting
The sand dunes are moving at a speed of 5-6 m per year. Stabilizing and planting eliminate the transfer and movement of sand and the threat of covering houses and other facilities with sand

How can they be sustained / enhanced? The farmers should be motivated not by prohibiting grazing on this site, but by its proper use (one can keep few sheep for personal needs, but grazing should follow all agreed rules). The farmers will get a double benefit: they will graze animals to supplement their diet and prevent the threat of covering the household with sand
The wind speed is reduced by 20-25% in the areas protected by the vegetation planted on the dunes. Reduced transport of dust in the air improves the living conditions in the houses and has a positive impact on people's health

How can they be sustained / enhanced? To expand and strengthen these positions it should be demonstrated to other farmers how this technology creates a comfortable environment. The people will understand that a neighbor's living conditions are better, and that the neighbor not only ensures the safety of his house against the sand, but also uses pastures and receives income

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?
The technology is expensive The state provides funds to cover the costs of materials for the land user
If the land user stabilizes the sand near his house, but the neighbors (neighbors can be different) allow their cattle to graze on this territory (land is owned by the state), then the farmer has no mechanisms to protect the territory from the animals coming from outside Transfer the land to private hands (the right of ownership or lease). Then the land users will take advantage of applying this technology on a large scale, because a small pasture area near the household is only convenient for keeping a few animals (weak and sick) for their personal use
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
The technology of stabilizing sand with mechanical sand dune fixation means made of plant material and with planting shrubs on them is costly The state finances such a technology when constructing the roads, railways and gas pipelines in the desert. Currently, the Uchadzhi village is being improved in Karakum desert, where the government finances this technology. Similar programs should be developed in the future for all villages in the desert. This provides the village with a reduction in fixed costs to clear the roads, farm buildings, schools and medical facilities of sand
There is no law on pastures A draft law is under consideration by the Cabinet of Ministers
