Title: Case Studies on Desertification

Publisher: Natural Resources Research XVIII, UNESCO/UNEP/UNDP, 280 pp.

Date: 1980 Language: English
Available: BiL Moscow, WGiSR UW Warsaw
Classification: 5A2, 5C1-2, 5D1a-b, 5D1e, 5D2b
Region: Global, ex-Soviet Union, Turkmenistan
Summary: This text consists of regional studies on desertification, and preventive measures. For the entire ex-Soviet Union, only two brief studies were prepared by the government: measures for combating desertification in the Golodnaïa Steppe (Steppe of Hunger, Turkmenistan, pp. 265-267), and methods of controlling desertification in Turkmenistan (pp. 267-269). The two papers cover the following subjects: irrigation, population increase, development of cereal cultivation and animal production. 23,000 ha of the Golodnaïa Steppe were irrigated prior to 1929, and 600,000 ha towards the end of the 1970's. New projects in irrigation development are planned. Irrigation in Turkmenistan is connected to the Karakumy Canal (900 km in length, rate of flow of 400 m3/sec, supplemented by 2,000 km of lesser canals). It is "the largest desert hydrotechnical project in the world" (p. 267). Its success depends largely on the central planning of irrigation (p. 267) and the size of agricultural operations (surface areas of state animal production: from 27,000 to 670,000 ha).
Sand dune fixation: 1951-1968: 140,000 ha, 1971-1975: 300,000 ha, 1976-1980 (planned): 330,000 ha.

Note: There is a French version entitled: "Etude de cas de la désertification."

Classification: 2A3, 2B2b, 3C3, 4A2
Region: Kazakhstan
Summary: A detailed description is presented of prairies in the valleys of the desert zone (natural environment, floristic composition, productivity). Factors of change in these prairies are given, particularly desertification caused by human action. The 5 stages of desertification are described in plains located in river deltas (pp. 71-73: degradation of water conditions, decrease in productivity); the length of time of each stage of desertification and the time necessary for the regeneration of vegetation once conditions return to normal are also presented. Charts show the changes in the floristic composition during the salinization process. The decrease in productivity due to desertification is presented in detail (pp. 92-152). It has fallen from 10,668 to 848 g/m2; the pastoral potential has diminished 30 times and more (p. 152); however, the root biomass decreases more slowly.

Recommendations: pp. 153-165: increase in and improved management of stream flows, controlled fires, improvement in agricultural techniques.

Region: Countries of Asia and the Pacific
Summary: The region studied, Asia and the Pacific, covers 31 million km3, or 23%, of the total area of continents (excluding Antarctica); in 1984 this region had 2.4 billion inhabitants, or 53% of the total world population. Although large areas of this region are affected by desertification (2.2 billion ha, including 440 million ha which are very affected), this area plays an important role in world food production. The chief factors which influence desertification in this region are the destruction of forests, the salinization of soil, the formation of ponds and wetlands by infiltration, wind and water erosion, and the degradation of rangelands.
The study of human factors in desertification is of primary importance for combating the negative effects of the relation between man and ecosystems. The problem of desertification caused by human activities was an important issue of the UN Conference on Desertification.

Title: Environmental Management in the Soviet Union

Publisher: Cambridge Soviet Paperbacks, Cambridge University Press, 314 pp.

Date: 1991 Language: English
Available: private collections
Classification: 2A1, 2A4, 2B2g-h, 2B2f, 4B
Region: Plains of southern Russia, southwestern Siberia, Kazakhstan, Aral Sea
Summary: This book covers a wide variety of problems relating to the degradation of the natural environment in the ex-Soviet Union, from the protection of nature reserves to Chernobyl. Problems of desertification are discussed in two chapters.

1) Land protection, pp. 196-212 - dangers resulting from dust storms. The territories in danger cover 900,000 km2 in the plains of southern European Russia and 700,000 km2 in northern Kazakhstan and southwestern Siberia. In the southern plains of Russia, particularly intense deflation has taken place in the years 1953, 1960, 1965, 1969, 1974, and 1984. Certain zones are affected by 20 dust storms per year and by the annual deflation of 2-7 cm of the soil surface. Protection could be assured by the planting of trees to preserve humidity in protective strips around fields. The plantation of protective strips has decreased from 44,000 ha in 1980 to 39,000 in 1985 and to only 29,000 ha in 1987. Included is a map of dust storm frequency.
2) Water crisis in Soviet Central Asia, pp. 213-232 (chapter prepared by P.P. Micklin and L. Harrison Fund). This chapter contains general information on irrigation development in Central Asia and on the problem of the Aral Sea. Various estimations of economic losses are given: in 1979 losses were estimated to be 5.4 - 5.7 billion roubles in Uzbekistan (total over a period of several years); in 1988 estimates were 100 million roubles in the Amu-Darya delta; in 1988, according to the press, losses equalled 1.5 - 2.0 billion roubles in the entire Aral Sea region.

Date: 1985 Language: Russian
Available: BiL Moscow, IG RAN Moscow, KR FAK Alma Ata, WGiSR UW Warsaw, UAM Poznan
Classification: 1B, 2B2e, 2B2f
Region: South of the Aral Sea, Uzbekistan
Summary: Desertification in the area south of the Aral Sea is connected, among other things, to hydrological deregulation in the Amu-Darya river delta and to the reduction in the level of the sea. Until 1961, infiltration of water from the sea into the delta caused the formation of lakes and marshes. The level of the sea has decreased 8 m during the years 1961-1981. Due in part to the geological structure of the region, water reflux has declined. It is predicted that the continual decrease in the level of the sea will cause a lowering of the water table within a radius of 200 km. If the level of the sea decreases by 30 m, the water table 15 km from the sea will lower by 20 m, 40 km from the sea it will lower by 15 m, and 75-130 km from the sea it will lower by 10 m. Specialists predict that if current trends continue, salinization of the Aral Sea will reach 34% by the year 2000. In this region soil salinization can be observed; there are patches of salt along the sea coast, and in dried up marshes and lakes. The deflation of sand and dust with a high concentration of salt constitute a significant danger. They settle mainly in the delta, but dust storms carry them long distances (up to 300 km). The mass of dust carried away each year by the wind is estimated to be 15-17 tonnes. The author suggests possible scenarios of the soil and vegetation change in the different stages of aridification. To conclude, Rafikov states that combating desertification is only possible when there is profound knowledge of the natural environment.

Summary: In the Ili basin, the aridification of the landscape, the increase in the continental character of the climate and the impoverishment in fauna result from the regulation of the stream flow and the collection of water for irrigation.

The Kapchagaï dam (28 km3; 2,847 km2): an analysis of changes in the chemical characteristics of water and soil (the reservoir has flooded areas of saline soil), the drying up of the delta, and the decrease in productivity of rangelands. In an area of 50,000 ha the initial productivity of 23-45 q/ha has declined to 7 q/ha. In the region formerly covered with reeds (130,000 ha, 22 q/ha) desertification and salinization can be observed. The surface area of the delta is 8,000 km2.

Lake Balkhash: as a result of the decrease in water influx in recent years, the level of the lake has decreased by more than 1.5 m, the coastline has moved 2-3 km to the north, in places up to 7-8 km. On the dried up land the soil is strongly saline. There is an increase in the salinization of the lake. The current of groundwater has reversed - water now flows from the lake towards the lower delta. Salinization is 1-3g/l near the sea and 10-20 g/l at the southern limits of the plain surrounding the lake. The negative ecological effects are magnified by the fact that the filling of the reservoir in 1974-77 coincided with a period of low stream flow of the Ili, which lasted several years.

Title: Soviet Environmental Policies and Practices. The Most Critical Investment.

Publisher: Dartmouth (Aldershot - Brookfield, USA - Hong Kong), 215 pp.

Date: 1991 Language: English
Available: Private collections
Classification: 2A4, 5B1
Region: Central Asia
Summary: The problems of desertification are considered in part in Chapter 1, entitled «Development of agriculture and the natural environment," pp. 33-66. This chapter contains statistical charts on the extent of water resources and consumption for each republic (Chart 3.6, p. 44). Water losses are significant during transport from the water supply point to the consumption points. In the entire USSR, 50.6 billion m3 were lost for 337 billion m3 used; in Uzbekistan, 16.9 billion m3 were lost for 73.9 billion m33 used; in Turkmenistan, 7.3 billion m3 lost for 22.5 billion m3. The author also presents theoretical calculations of water costs in 1983 and 1984, information on progress in irrigation, mineralization of water in the Aral Sea basin, and on page 57, information on the salinity of the water in large reservoirs that collect drainage water.
In 1990, the area of irrigated land in the USSR was 23.1 million hectares with a drainage system covering 18.5 million hectares. By the year 2000, it should extend to 32 million hectares with a drainage system covering 21 million hectares. On page 60, the cost of irrigation reconstruction according to 1985 conditions is estimated (the author's calculations are based on various Soviet sources). Of the 17.1 million hectares of irrigated land in 1985, 6.4 million hectares will require reconstruction, which would cost 32 billion roubles (including Russia with 1.9 million hectares - 9.3 billion roubles, Uzbekistan with 1.3 billion hectares - 9.3 billion roubles, the Ukraine with 0.9 million hectares - 6.7 billion roubles, and Kazakhstan with 0.7 million hectares - 3.6 billion roubles).

Summary: This text discusses the cultivation of Glycerrhiza glabra L. on sands near the oases of Turkmenistan. The objective is sand stabilization, at the same time providing animal feed, while the roots supply a rare raw material used in the pharmaceutical and food industries. The natural resistance of this plant has considerably diminished during recent years. The authors discuss the ecological requirements of the plant and illustrate its root system. The cultivation of this plant enriches the soil in nitrogen.
An experimental cultivation of Glycerriza glabra L. was started on seven hectares near the Amu-Darya River (in the southeastern Karakumy Desert). This experiment was a success. With optimal irrigation, 16-18 tonnes/ha of dry root matter were obtained in two years. The straw of this plant has proven to be a very useful animal feed.

Region: Russia (Kalmyk, black lands)
Summary: A long-term cyclic decline in precipitation in the northern Caspian plain in the years 1940-1950 diminished the rangeland potential. Animal production has increased, especially since the end of the 1960's, which has caused a marked degradation. Calculating the costs of soil rehabilitation and the revenue from animal production, the authors have prepared a mathematical model of optimal rangeland restoration over a period of 20 years. In the first phase, revegetalization should cover 20-25% of rangelands per year, then 10 15 % per year, stopping when 83 % of the land is non-degraded, supporting 0.6 sheep per hectare. This alternative assures the maximum profit.

Region: Central Asia (Tajikistan, Turkmenistan, Uzbekistan, Kazakhstan)
Summary: This publication is probably the most up-to-date report on the deserts of Central Asia. The history of research on deserts and their economic development is discussed, including the topography of sand deserts (pp. 213-236), the desertification process and means of combating it (pp. 236-266), and predictions of future ecological changes in deserts resulting from human activity (the chapter with this title is a regional look at zones lending themselves to irrigation, containing information on the potential ecological risks). Desertification is perceived as "a process which initially manifests itself by a decrease in the biological productivity of ecosystems" (p. 236). The natural factors in desertification are treated superficially, with emphasis on sand and dust storms, chief factors in this group. Greater attention is given to human factors; numerous examples are given, such as overcropping and overgrazing, excessive use of water for irrigation, transport routes crossing deserts, etc. There are also examples of the degradation of the natural environment. Among the methods of combating desertification, sand dune stabilization is emphasized, in particular using chemical methods.

Definition: "Desertification": process initially manifested by a decrease in the biological productivity of ecosystems.

Natural factors of desertification: Chief factors: cold autumns and winters, slowing the development of short-lived vegetation, less than average precipitation over several years, decrease in the flow of large rivers, development of erosion and deflation, modifications in the surface area of lakes, and increase in the salinity of enclosed lakes.
