Publisher: Akadïemiïa Naouk Azïerbaïjanskoï SSR. Institut Gïeografii (Academy of Sciences of Azerbaijan, Geographical Institute), Baku, 22 pp.

Date: 1982 Language: Russian

Classification: 2A1, 2B1, 5C2
Region: Azerbaijan, Dagestan
Summary: Presentation of a doctoral thesis at Baku. Analysis of soil types and description of wind erosion and the different factors which can contribute to it (results from field work). For example, a strip of forest (windbreak) 160 m long, 7 m wide and 3.0 to 4.5 m high (composed mainly of acacias) causes a significant decrease in wind speed for up to 50 m (from 4.9 m/s to 1.4 m/s, speed measured 10 cm above the ground), but at 100 m from the strip, the speed increases again to 4.9 m/s. Wind erosion affects 53.6% of southeastern Dagestan (light erosion affects 10.4% of the area of the region, moderate erosion - 10.5%, heavy erosion - 28.9%; sand dunes cover 3.8%). Sands and solonchaks are the most eroded. In Dagestan the acceleration of erosion has been caused by over-exploitation (without indicating what types).

Two schematic maps:

1. Soil types (from the point of view of their vulnerability to wind erosion, 13 types)

2. The danger of erosion and measures for controlling it. Six types of terrain are identified and various solutions are suggested, such as: forest strips, drainage as a means of desalinization, revegetalization, regulating livestock farming and others.

Plants: Acacia, Maple

Classification: 0
Region: Kazakhstan
Summary: A map to the scale of 1:2,500,000, showing the landscape types in Kazakhstan, prepared using materials of 1:1,000,000 and others more detailed. In all, 485 landscape types are identified, including 80 deserts, 51 semi-deserts, 49 of the arid steppe type.
Desertification processes are not shown on the map. Morphological criteria differentiate landscape types. This is the first map of landscape types drawn up in one of the republics of Central Asia. Contemporary maps which show the processes of desertification, the vulnerability of ecosystems and environmental changes caused by human activities have been developed on the basis of this map of natural landscapes. (The same is true for other states of Central Asia).
Landscape types - deserts, semi-deserts and arid steppes - are identified according to the type of vegetation, and, in particular, the percentage of soil devoid of vegetation, but the map's legend does not take this into account. Within each group, several types can be identified which are uniform in terms of topography, the range in altitude, the soil and the vegetation. For example: semi-deserts; flat coastal plains; clay soils, sandy clay, and sands; landscapes with Festuca sulcuta vegetation types (solonchaks, solonïetz).

Classification: 0, 1A, 1C, 1D, 2B1, 2B2c, very generally 2A, 3C
Region: India, Turkmenistan
Summary: A comparative study of the natural environment (very good description) and of the human exploitation of the two deserts. Each chapter is divided into two parts: one prepared by an "ax-Soviet" writer (for the Karakumy Desert), the other by an Indian specialist (for the Thar). Desertification: Kharin N.G. and Babaïeva T.A., pp. 280-288, for Turkmenistan; Venkateswarlu J., Sen A.K., Gupta G.P., pp. 288-302, for India.
Desertification in Turkmenistan: general information. According to the authors the chief factor is overgrazing. The schematic map of Desertification in Turkmenistan shows the intensity of Desertification (6 degrees), the elements of Desertification (5 elements), the causes of Desertification (6 causes: insufficient grazing, overgrazing, over- exploitation of woodlands, use of fragile lands for agriculture, mining, construction, natural processes), and the improvement of the natural desert environment (2 types). The authors also show the differences in the intensity of Desertification in different administrative regions (oblasti) of Turkmenistan.

Note: According to Russian participants there is an English version in India. Title: Karakumy Desert and Thar Desert.

Definition: Desertification (p. 280): "The intensification and/or expansion of desert conditions constitutes a process which leads to a decrease in the productivity of ecosystems; this decrease, in turn, leads to a decline in pastoral resources, agricultural production and the deterioration of the conditions of human life" (Institute of Deserts). The Indian researchers' definition is very different: it is limited to Desertification caused by human activity.

Title: Opustynivaniïe v Uzbïekistanïe i bor'ba s nim (Desertification and combating desertification in Uzbekistan).

Publisher: Fan, Tashkent, 156 pp.

Date: 1988 Language: Russian
Available: BiL Moscow
Classification: 1C4 (cartography), A, 2B2e, 3B-C, 5C
Region: Uzbekistan
Summary: A summary of documents, probably the most up-to-date on desertification in Uzbekistan. Presented in 5 chapters: 1) The natural environment as the background of desertification; 2) Factors and causes of desertification; 3) Current conditions and predictions; 4) Cartography of desertification; 5) Combating desertification.
Chapter 2 focuses on the drop in temperature in the 1950's and 1970's, which contributed to droughts. Human activity is considered to be the main factor in desertification, especially overgrazing (examples on pp. 32-35). Desertification caused by modern technology plays a major role, especially trucking, which destabilizes ecosystems. Intensively-used unpaved truck routes often reach 0.5-1 km in width; north of Ustyurt, even up to 1-2 km. The criteria of desertification, chiefly an analysis of vegetation, are described on pp. 44-50.
In chapter 3, five natural regions are identified (with schematic maps). The zone near the Aral Sea is analyzed in the most detail. Predictions are pessimistic.
Chapter 4 presents the method used in the preparation of the map "The danger of erosion in the drylands of Uzbekistan"; there are charts with the criteria of the degradation of vegetation (pp. 80-81), wind erosion (p. 85), water erosion (pp. 89-90), salinization (pp. 93-95), desertification caused by modern technology (6 types, p. 98), a classification of landscape types (pp. 102-103), a chart of the current state of desertification according to landscape type (p. 104). The current state of desertification is shown on the map p. 100. Chapter 5 covers: sand dune fixation; desalinization, pasture improvement, combating desertification south of the Aral Sea, the rational use of pastures and irrigated lands.

Note: Extensive bibliography, exclusively in Russian.

Desertification caused by modern technology: Destruction of the plant cover and soil resulting from the construction of roads, factories, mines, housing developments, railroads, irrigation installations, etc., and intense off-road vehicle traffic.

Publisher: Elm, Baku, 180 pp.

Date: 1979 Language: Russian
Available: BiL Moscow, WGiSR UW Warsaw
Classification: 0, 2B2j, 5C2, 5C4
Region: Azerbaijan
Summary: In this description of the environment and natural resources of the Apsheron Peninsula, where Baku is located, problems of the degradation of the environment are treated superficially; damage is mainly due to the mining industry.
The peninsula is affected by soil salinization and by wind erosion. Information is presented on fences which stop sand encroachment and further the formation of dunes in designated places, also on forest strips (recommended species: Ulmus campestris, Haloxylon sp., Ficus carica), seeding (species for sand dune fixation are not mentioned), and on the rinsing of solonchaks (saline soils).
The authors describe the important role of park management in towns for improving the quality of life; for example, at Baku, parks covered respectively: 309 ha in 1950, 1,160 ha in 1960, 5,500 ha in 1975. The plan for the years 1976-1980 was to enlarge these areas by 6,640 ha (charts pp. 128-9). In 1975 parks, forest strips, and tree and shrub planting (including vines) covered 13,169 ha of the peninsula.

Note: Species recommended for windbreaks: Ulmus campestris, Haloxylon sp., Ficus carica.

Summary: In the ex-Soviet Union, irrigation was begun in Antiquity, covering a territory of 8 to 10 million ha, located in Central Asia and in southern Kazakhstan. Half of these lands were in the basin between two rivers: the Amu-Darya and the Syr-Darya. They have great scientific and practical importance and could be redeveloped. For several years, archaeologists, geomorphologists and pedologists have carried out comprehensive research using aerial photographs. The purpose of these studies was to explain certain issues:

1) when and which crops were grown in which soil and for how long were they irrigated?
2) when and why was farming stopped?
3) how long have they been going through the desertification process?
4) what changes have the landscape and the soil undergone?
5) what are the factors which have determined these changes?

An archaeo-geomorphological map has been drawn up, based on this research, showing cultivated lands in Antiquity, their irrigation system and the time of use. These data are very important in the planning of a new irrigation system.

Available: IG RAN Moscow, WGiSR UW Warsaw
Classification: 2B2a, 2B2, 2C-D, 3A-B
Region: Central Asia, Kazakhstan, the Caucasus
Summary: This collection of 33 articles spans the last 2,000 years. The problems dealt with are diverse, but most work focuses on changes in the sea level and the coast line of the Aral and Caspian Seas. However, the changes in question depend on factors so varied that their usefulness in analyzing climate change is low. Palynological analyses give the most concrete results. They do not show a constant trend in climate change, but long-term variations. Today the climate is evolving towards a dry period.
In the Caucasus, the most humid period was 1750-1300 B.C.; it was followed by a drier period; the driest period was in the 12th and 13th centuries (pp. 61-70, chart p. 69). In Central Asia, aridification and accompanying changes in the flora date from 4,000 years ago (p. 174). The zone with the widest range of temperature and atmospheric pressure began moving 10°-15° to the north, putting Central Asia between the northern and southern zones of atmospheric fronts, which caused a decline in precipitation. In the subsequent period, minute climatic variations have been observed in various regions of Central Asia (for example, in Fergana where the most humid period was the end of the first millenium B.C. and in the 9th and 12th centuries - p. 221). No regularities in these variations were observed.

Available: BiL Moscow, WGiSR UW Warsaw
Classification: 5C2, SB1-2
Region: Turkmenistan
Summary: This publication is an outline of methods of protection against sand encroachment (fences, barriers, etc.) and the stabilization of sand by mechanical and chemical means. There is no information on the afforestation of sands or on methods of revegetalization, despite the book's title. However, there is a detailed description of techniques of protecting roads and industrial buildings from sand encroachment, an economic calculation for different techniques of chemical stabilization, including transport costs (rare in Soviet literature), and the state of these methods in the early 1980's. At that time, stabilization with petroleum and its derivatives was the least expensive method and lasted 2 to 5 years.

Description of methods of chemical stabilization of sands:

In 1975 in Tashkent, a vehicle was made for the purpose of spraying sand with fixatives. The most frequently used substances were petroleum and its derivatives: nerozine, mulch with bitumen, mulch with fuel oil, bituminous emulsions, polymers K-9 and K-6, sunak, BRP-1, latex, SSB. Occasionally, aqueous solutions of polymers with clay in various proportions have been used; in this case, a permeable or impermeable cover is formed on the sand. Stabilization lasted 2 to 4 years depending on the substance used (the most economical were oil mulch with additives, and polymers).

Classification: 5B1, 5C1, 5C4, 5D1a, 5D1d
Region: Turkmenistan
Summary: In Turkmenistan, out of 36 million ha of pasturelands 22 million are irrigated, or 60%. There are inequalities among the systems, both in the layout of water points and in the technical condition of their equipment. The optimal distance between water points is 5 to 8 km so as neither to weaken the animals nor destroy the pastures by their movements. Studies of this matter show that when the distance between water points is 2 km, the region irrigated can be 1,256 ha, and the cost of irrigation is 8.4 roubles per hectare. When the distance between water points is 6 km, 11,000 km can be irrigated for a cost of 52 roubles per hectare; when the distance is 10 km, irrigation can cover 31,400 hectares with a cost of 34 roubles per hectare.
As for the depth of wells, the most economical are those 70 m deep. They supply more than 30m3 of water per 24 hours, with a cost of 22 roubles per m3 of water.
The irrigation of large areas is planned using aqueducts. In addition to irrigation, work has begun on projects for improving the quality of pasturelands, especially in the Karakumy Desert. Several other projects have been carried out for the purpose of protecting and improving plants as well as for the formation of man-made pasturelands.
During the ninth Five-Year Plan, these projects have consumed 1.835 million roubles. The improvement of pasturelands is planned for an area of 2.5 million hectares.

Classification: 1C1, 2B2c
Region: Central Asia (particularly Turkmenistan), Africa (Libya)
Summary: Presentation of a method of analyzing aerial photographs and satellite imagery used to study the natural environment of deserts and pasturelands. Primarily, imagery from "Salyut" was used, but also some from "Meteor." One article is devoted to the range of desertification in Turkmenistan (pp. 25-43). The area affected by a given type and degree of desertification is indicated for each administrative unit of the republic. Figures are presented for the entire republic: 35.25% of the area is not affected by desertification; 11.05% light desertification; 15.65% moderate desertification; 5.26% strong desertification; 3.87% extreme desertification. Surface water covers 2.07%. Territories affected by the degradation of vegetation cover 38.19% of Turkmenistan, by wind erosion 7.59%, by fluvial erosion 5.12%, by soil salinization 10.97%, by desertification caused by modernization 0.85 % (3,947 km2). Forests planted on sands cover 0.95% (4,633 km2), protected lands near railroad lines 1.36%, improved lands near canals 4.78%, natural reserves 2.78%. This means that on nearly 10% of the territory there seems to be an improvement in natural conditions.

Analyzing satellite imagery:

Satellite imagery is used primarily to interpret the state of the vegetation and the topography. Zones are discerned by their tone, their structure and the clarity of identical borders. All the elements represented by points or lines on the satellite imagery are identified by comparing to maps. In the field, tones and structural elements corresponding to the imagery are identified. Particular attention is paid to the state of vegetation near water points and to dunes. When possible, imagery from different years are compared to understand the dynamics of change.

Region: Ex-Soviet Union - Central Asia
Summary: An anthology of 15 articles dedicated to M.P. Pïetrov on his 75th birthday, and a bibliography of his work. The articles deal with the natural environment of Central Asian deserts (sand deserts in particular), physical and geographical regionalization and methods of drawing up geomorphological maps using satellite imagery. The study "Large Central Asian canals and the combat against desertification" (pp. 136-146) contains information on the Karakumy and Amu-Bukhara Canals. Conditions for the year 1976 and plans (in parentheses) are as follows:

- The Karakumy Canal: length - 1000 km (1400 km), rate of flow 400 m3/sec (800 m3/sec), gravitation system, irrigated area 520,000 ha (1 million ha);
- The Karchin Canal: 200 km, 200 m3/sec (550 m3/sec), 200,000 ha irrigated (850,000ha);
- The Amu-Bukhara Canal: 196 km (234 km), 269 m3/sec (300 m3/sec), 250,000 ha irrigated (400,000 ha). Excessive water consumption decreases the level of the Aral Sea, which brings on desertification, especially in the Amu-Darya and Syr Darya deltas. Short-term prevention: conducting irrigation water into the Aral Sea, possibly the future transfer of water from Siberian rivers. A study (pp. 84-102) of the topography formed by wind effect, and on general methods of sand dune stabilization is completed by information on plants used to this end

Plants used to stabilize sands: Ammodendron conollyi Bunge (sand Acacia), Haloxylon persicum Bunge ex Boiss (white saxaoul), Aellenia subaphylla var. arenaria (Chenopodiaceae), Ephedra strobilacea Bunge (Ephedraceae), Salsola richteri (Mog.) Karl et Litr., S. paletzkiana Litr.., (chenopodiaceae), Calligonum sp.

Classification: 1A-B, 2A, 2B2, 3C3-5, 4A1-2, 5A-D
Region: Soviet Central Asia, Kazakhstan
Summary: This document describes the climatic conditions of arid and semi-arid lands in Soviet Central Asia and Kazakhstan, and formulates definitions of desertification. Desertification factors according to B. G. Rozanov (1977, cf. bibl. entry 52) are presented, as are the natural and human factors in desertification, the stages of desertification in Central Asian pasturelands as a result of excessive animal production, (the succession of plant associations, examples, decline in the productivity of pasturelands). Information is given on: desertification observed along the Amu-Darya and Syr-Darya deltas after the diversion of water for irrigation; projects in the USSR in the development and improvement of pasturelands; irrigated agriculture with numerous maps and examples such as the Steppe of Hunger (Golodnaïa Steppe), and the stabilization of sands by afforestation (this information is on Central Asia and the northern Ukraine). The problem of sand stabilization is presented with a description of traditional and modern methods, species selection, seedling survival, the hardening of soil using chemical methods (fuel oil, petrol, various bituminous substances, etc., information on the depths of these treatments and on the cost: fuel oil mulch 43-53 roubles/ha, petroleum mulch 52 roubles/ha, reinforcement with fences. In Turkmenistan, afforestation and revegetalization projects have been implemented on sands at the rate of 80,000 ha per year (total area of sand dunes: 1,323,000 ha).

Remarks:

1. Rich bibliography (176 titles, mostly in Russian).
2. Russian version - bibl. entry 71.
3. The report is an official document presenting the position of the government of the USSR.

Species used in the afforestation of sands: kandym, cherkez, black saxaoul, Calligonum.

Desertification factors according to B.G. Rozanov (1977)

1. Degradation of the vegetation and soil erosion as a result of overgrazing.
2. Increase in erosion and deflation due to the use of lands for agricultural.
3. Destruction of vegetation for use as energy source.
4. Destruction of vegetation and soil as a result of the construction of roads, factories, mines, housing developments, irrigation installations, geological research.
5. Destruction of vegetation and soil caused by motor vehicle traffic.
6. Destruction of vegetation and soil by livestock near water points.
7. Secondary salinization of soil in irrigated zones.
8. Expansion of saline deserts in basins without permanent stream flow.

Summary: This document is a follow-up to a seminar held in Ashkhabad in 1988. Ninety texts are included, 33 of which were published in two subsequent issues of "Problïemy osvoïeniïa pustyn"'. The largest number (18) are articles concerned with desertification and its intensification in Africa, 6 are devoted to theoretical considerations, to research methods in studying desertification and to techniques for its prevention; 8 articles are on combating desertification in Soviet Central Asia and in Kazakhstan (particularly as it relates to irrigation), and on the possible use of this experience in Africa; 1 text deals with Iraq. The final resolution contains a definition of desertification (see: Definition).
The majority of these articles deal with problems of the environment, while social concerns are treated only marginally. In N° 3, pp. 5-10, the article entitled "From the application of Central Asian experiences to the implementation of agrarian reform in Africa" is a description of reforms introduced in the years 1921-1922, leading to the transition from the former feudal system of land and water in Turkmenistan.

Definition: "Desertification, a process caused by human economic activity, especially the use of water and soil resources in agriculture, results in the degradation of the economic systems of land, not only in arid and semi-arid regions, but also in marginal lands.

Summary: An account of the 1981 conference in Ashkhabad. This volume contains 64 brief entries divided into 5 parts: a) climate and natural resources, regionalization and protection of the environment (notably the future of the Aral Sea, description of its degradation, and, again, transfer of water from Siberian rivers); b) research on deserts using remote sensing (9 articles on methodology); c) soil resources (erosion and deflation of deserts and the steppes along the Volga; description of the process whereby an excess of fertilizer and of cultivation influence salinity); d) water resources of deserts (use of groundwater, mineralization of water for irrigation, the importance of the Karakumy Canal; the chemical features of the Aral Sea and its future; e) sand dunes and preventive measures, characteristics of sands and their water balance, protection of railroads from sand encroachment, tree plantation, using sands for the cultivation of sorghum and rice, sand storms, sand stabilization using chemical methods).

Brief description of methods of desert research: Classical methods of analyzing aerial photographs and satellite imagery (cf. bibl. entry 10) were used to draw up maps of vegetation, the condition of pasturelands, soils, zones requiring protection, soil salinity. A light to completely white phototone, pale contours and the presence of darker patches are important for detecting salinization. The scale of these maps is from 1:10,000 to 1:1,000,000, and smaller. For interpreting satellite imagery, the most rapid method is that which uses maps showing landscape types.
