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)

The technology was developed in the 1950’s-1960’s to secure economic projects

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation

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

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

3.7 Main types of land degradation addressed by the Technology

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)

3.8 Prevention, reduction, or restoration of land degradation

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
