2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Collecting rainwater in artificial trenches on hill and mountain slopes for the accumulation of water in the soil around the roots of trees planted in the trenches

2.2 Detailed description of the Technology

Description:

Intensive grazing and the felling of trees and shrubs in Turkmenistan led to the degradation of vegetation and soil. Reforestation through planting on slopes and using moisture accumulating trenches in non-irrigated bogara (rainfed) lands leads to a high survival rate of trees, even in years with low rainfall and without irrigation.
A moisture accumulating trench is triangular in cross-section; its depth is 0.4 m and the width on top is 0.7 m. It is made with the help of a single-bladed plough (the soil is dumped towards the slope) or by mounted trench diggers (the upper ridge of soil from the trench is moved to the lower slope). To remove excess water, a short dam is made at the end of the trench angled towards the slope. Marking of the trench’s location should be made perpendicular to the slope. This allows water to evenly fill the trench. If the slope is to 60-100% covered withherbaceous vegetation and does not exceed 16% steepness, the trenches are furrowed at a distance of 12 m. Seedlings are planted in the planting holes 5 m apart at the bottom of the trench. The height of the seedlings should be no less than 50 cm.Surface runoff collecting in the trenchesseeps into the soil and supplies roots with water. Native species have been planted, including Turkmen juniper, Turkmen maple and common almond. The technology also allows for the cultivation of alien species such as Eldar pine, American arborvitae and Red cedar

Purpose of the Technology: The aim of this technology is to create favourable environmental and social conditions in the Konegumbez village area through the restoration of degraded forests by planting seedlings in moisture accumulating trenches that increase the survival rate of plants in non-irrigated boraga lands

Establishment / maintenance activities and inputs: The Konegumbez village is located in the “Nokhur” pilot area of the “Combating land degradation in the three regions of Turkmenistan” project (2002-2007, GIZ-CCD/NIPRZHM). A group of volunteer foresters consisting of local activists was established with financial support and the assistance of both consultants and the project team to restore the forests around the village. The entire population of the village has been involved in the afforestation of 4 ha of land.

Natural / human environment: Konegumbez village is located 150 km west of Ashgabat in the Central Kopetdag at an altitude of 1000 m. The water table is located at a depth of 150-180 m. The ground water is fresh . The soil type is light and dark grey. The vegetation is comprised of grass-forb with sporadic juniper plants. The annual amount of precipitation is 325-355 mm and the average annual temperature is 10.9ºC. The frost-free season last for 190-222 days. The population of Konegumbez village is 400 people People in the village are engaged in livestock breeding. They also grow vegetables and fruits. The total area of pastures amounts to 3,000 hectares. The limited water supply and restricted pasture areas are important constraints for the living conditions of the local population

3. Classification of the SLM Technology

3.1 Main purpose(s) of the Technology

  • reduce, prevent, restore land degradation
  • preserve/ improve biodiversity
  • create beneficial social impact

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

Grazing land

Grazing land

Extensive grazing land:
  • Nomadism
  • Semi-nomadism/ pastoralism
Main animal species and products:

Nomadism: Sheep and cows are grazed 11 months a year on natural pastures, where shrubs and trees also grow

Semi-nomadism / pastoralism: Several farmers’ families put their small cattle together in one herd and graze them by turns. Additionally they are engaged in land cultivation. Cows are grazed without a shepherd

Forest/ woodlands

Forest/ woodlands

  • Sanitation cutting of shrubs
Products and services:
  • Fruits and nuts
  • Grazing/ browsing
Comments:

Major land use problems (compiler’s opinion): The number of animals exceeds the capacity of pastures (this results in an increasing number of innutritious and unpalatable plants), trees and shrubs are felled for fuel and construction purposes (consequently leading to a reduction of the water debit in springs and rivers and an increase in floods and soil erosion on slopes)

Major land use problems (land users’ perception): Irrigation water shortage, lack of pastures for grazing animals and mud flows washing away the vegetation planted near the river beds

Grazingland comments: Members of the “Yenish” Daikhan Association are engaged in livestock breeding and land cultivation. Small cattle and cows are grazed for 11 months in pastures covered with forests. Forests mainly consist of juniper stands, which were cut on the flat and slightly sloping parts (easily accessible by people), and now these areas are used only as pastures for grazing animals

Sanitation cutting of shrubs: Felling the old dry and diseased trees as well as trees broken by the winds and mudflows

Problems / comments regarding forest use: Currently the entirety of the mountainous part of large villages has access to gas. Cutting down trees for fuel has declined sharply. Tree felling is only made to construct outbuildings.

Future (final) land use (after implementation of SLM Technology): Mixed: Ms: Silvo-pastoralism

Type of grazing system comments: Members of the “Yenish” Daikhan Association are engaged in livestock breeding and land cultivation. Small cattle and cows are grazed for 11 months in pastures covered with forests.

Region (oblast) - velayat, district - etrap

All the forests in Turkmenistan form the State Forest Fund, which is 9.9 million hectares (including protected areas). The total area of the mountain state forest fund is 524 hectares, and the area covered by forest is 146 hectares. Most of the forest fund is managed by forestry companies consolidated into the “Gek Gushak” joint-stock company and by the enterprises and organizations of the Ministry of Nature Protection. The mountain ecosystems of Turkmenistan include deciduous (at a height of up to 650 m above sea level), juniper woodlands (700-2600 m asl.) and mountain steppes (2700-3000 m). The deciduous mountain woodlands include ecosystems that consist of Griffith’s Redbud (Cercis griffinhii), Turkmen maple (Acer turcomanicum), fluffy maple (Acer pubescens), Caucasian hackberry (Celtis caucasica), bladder senna (Colutea buhsei) and others species that grow on dry stony canyon slopes. Arid juniper woodlands grow together with the mountain steppes and sporadically occur in an area of 42 thousand ha; they never form large solid massifs. These areas are good pastures for grazing animals. Deforestation has led to a change in the water and wind conditions, which adversely affect the productivity of springs and pasture vegetation. Therefore, one of the factors named by the people in Kenegumbez village among those having negative social and environmental impact on mountain areas, is forest degradation (deforestation and overgrazing). Within the framework of the project, afforestation work has been carried out in an area of 50 hectares near the village in a participatory way. Different methods have been used to demonstrate afforestation techniques and to train people: the normal planting of seedlings and watering of plants with water-carrier vehicles for the first year, as well as restoring forests using water-saving techniques (collecting rainwater in trenches and drip irrigation). The technology, including planting forest crops in artificially made trenches, ensures a good survival rate of plants without the need of additional watering. A dedicated collection of rainwater in trenches increases the amount of moisture in the soil horizons and the depth of moisture. The method was tested on a smooth slope at an altitude of 1200 m above sea level, where only 3-4 juniper trees were growing on 4 hectares of land. Furrowing was carried out, taking into account the grass cover that allows to collect sufficient rainwater in the trenches as well as the area needed for nutrition of adult plants. Experience has shown that, under our conditions, for juniper and other plants it is better to dig furrows 12 m apart and plant seedlings in a trench with 5 m distance between plants, i.e. 170 pcs/ha

Secondary types of degradation addressed: Hs: change in quantity of surface water

Main causes of degradation: over-exploitation of vegetation for domestic use (Felling trees for fuel and construction purposes drastically reduced the vegetation biomass and changed the habitat of birds and animals), overgrazing (Overgrazing leads to the substitution of edible species with inedible species (weeds).), population pressure (The number of animals grazed exceeds pasture capacity by 1.5-2times.A lack of grazing management leads to destruction of undergrowth and hinders maturation of seeds of pasture species and their sowing)

Secondary causes of degradation: disturbance of water cycle (infiltration / runoff) (Degraded land reduces the absorption of precipitation by soil, which leads to a moisture deficiency in the soil and a reduction in active plant growth. Runoff to gullies is increasing), change in temperature (An increase in temperature leads to increased evaporation from the soil surface. Accumulating additional moisture in the soil by the trenches reduces such negative impacts), droughts (In tukmen mountains drought occurs 3 to 4 times in 10 years, affecting the productivity of plant communities. An excessive number of animals grazed on pastures increases degradation of the vegetation), governance / institutional (The absence of a plan for using the village pastures leads to the degradation of vegetation from overgrazing and inappropriate pasture use)

6.4 Cost-benefit analysis

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

slightly positive

Long-term returns:

very positive

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

slightly positive

Long-term returns:

very positive

Comments:

In the short term, degraded forest and pasture vegetation restores and provides seeds the ability to self-regenerate and for the regeneration of neighboring areas. In the long term, the forest and pasture vegetation recovers

6.5 Adoption of the Technology

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

8 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?
  • 10-50%
Comments:

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

Comments on acceptance with external material support: 5 families from the group of volunteer foresters participated in preparation for the planting and in furrowing trenches. The project provided 100% of the funds

3 land user families have adopted the Technology without any external material support

Comments on spontaneous adoption: Currently, this technology is used by 3 farmers for the greening of non-irrigated household plots

There is a little trend towards spontaneous adoption of the Technology

Comments on adoption trend: The households are mainly located on steep canyon slopes, so applying this technology or its adaptation requires significant financial and labour costs (manual labor and a bulldozer to construct the terraces). Therefore, if moisture accumulating trenches are furrowed manually, the planting areas would not be very large; plants are mainly cultivated by people who love gardening

6.7 Strengths/ advantages/ opportunities of the Technology

Strengths/ advantages/ opportunities in the land user’s view
Plants are better rooted in the areas with the forest species planted in the trenches

How can they be sustained / enhanced? We guarded this area, and now we are grazing our sheep only in winter when there is snow. Therefore, these trees will remain for long time
Trees planted in the rainwater accumulating trenches at the site grows faster in comparison to the usual plantations
Some of our farmers use similar technology (changing the distance between the furrows) for greening and planting almonds near households on degraded non-irrigated lands

How can they be sustained / enhanced? We believe that young people building new houses will use this technology, because there is a lot of land available but not enough irrigation water. This technology will help to green the households
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
This technology can be used to restore the forest or to create a garden on non-irrigated lands (bogara) with a high risk for farming

How can they be sustained / enhanced? Climate change that leads to increased temperatures and shortage of irrigation water will extend the arid areas. Demand for this technology or its varieties is always high, because it improves the plants’ survival rate, even in dry years
This technology does not require watering the planted forest for the first year after planting

How can they be sustained / enhanced? When properly managed, the forested area can be used perpetually
The depth of moisture near the root system is 1.8 times greater than in virgin soil due to the collection of rainwater in the trenches

How can they be sustained / enhanced? The trenches can be used for 10 years with no extra costs.
In dry years the survival rate of plants is reduced to 30-40% in plantations withouth water collection trenches; the use of the technology increases the rate to 85%.
The productivity of pasture vegetation has been increased by 3 times from 4 centner/ha to 11.8 centner/ha

How can they be sustained / enhanced? When properly managed, the forested area can be used in perpetuity and will constantly expand due to natural regeneration

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 good, but the 0.25 ha of land near my house are state owned and allocated to me by the government. If I were to fence the nearby degraded lands, my neighbors or the forestry service have the right to deprive me of this land It is necessary that the government allows the use of this land
If we plant forests on large areas and temporarily guard them, then we will have no pastures to graze our livestock If the government would provide us with financial support for afforestation and use of this technology in our pastures, we would select suitable places and plant the trees. We would also guard and manage the plantations
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
The area with planted forest should be guarded for 4 years. Regulated grazing. In the second year after planting, only sheep may be grazed on this area (in early spring or winter, when there is no snow). Sheep mostly eat the leaves and stems of herbaceous plants.
In the Soviet Union, when afforestation was carried out, the planting area was completely closed to grazing animals for 5-6 years. Therefore, the local communities did not like such measures. Planting forests is a nationwide problem and it should be solved systematically according to the plan developed, taking into account all the aspects of grazing animals on farms. This year the Forest Act came into force, confirming the need for restoration of forest resources
