Environmental Problems of Central Asia and their Economic, Social and Security Impacts NATO Science for Peace and Security Series This Series presents the results of scientific meetings supported under the NATO Programme: Science for Peace and Security (SPS). The NATO SPS Programme supports meetings in the following Key Priority areas: (1) Defence Against Terrorism; (2) Countering other Threats to Security and (3)NATO, Partner and Mediterranean Dialogue Country Priorities. The types of meeting supported are generally "Advanced Study Institutes" and "Advanced Research Workshops". The NATO SPS Series collects together the results of these meetings.The meetings are co- organized by scientists from NATO countries and scientists from NATO's "Partner" or "Mediterranean Dialogue" countries.The observations and recommendations made at the meetings, as well as the contents of the volumes in the Series, reflect those of parti- cipants and contributors only;they should not necessarily be regarded as reflecting NATO views or policy. Advanced Study Institutes (ASI) are high-level tutorial courses intended to convey the latest developments in a subject to an advanced-level audience Advanced Research Workshops (ARW) are expert meetings where an intense but informal exchange of views at the frontiers of a subject aims at identifying directions for future action Following a transformation of the programme in 2006 the Series has been re-named and re-organised. Recent volumes on topics not related to security, which result from meetings supported under the programme earlier, may be found in the NATO Science Series. The Series is published by IOS Press, Amsterdam, and Springer, Dordrecht, in conjunction with the NATO Public Diplomacy Division. Sub-Series A. Chemistry and Biology Springer B.

FOREWORD The Aral Sea that was once a thriving body of water is no more. That sea is dead. “Long Live the Aral Sea”. What does exist in its place are the Aral Seas, that is, there are in essence three bodies of water, one of which is rising (the Little Aral), while the other two, though marginally still con- nected, continue to decline in level. In 1960 the level of the sea was about 53 m above sea level. By 2006 the level had dropped by 23 to 30 m above sea level. This was not a scenario generated by a computer model. It was a process of environmental degradation played out in real life primarily as a result of human activities. Despite wishes and words to the contrary, it will take a heroic global effort to save what remains of the Big Aral. It would even take a degree of sacrifice to restore it to a previous acceptable level. The setting There are several countries in the Aral Sea Basin. Most people refer to the five former Central Asian Republics of the Soviet Union as THE basin states: Turkmenistan, Kazakhstan, Uzbekistan, Kyrgyzstan and Tajikistan. However, Afghanistan and Iran are also in the basin, with only 1% on Iranian soil and an estimated 17% on Afghanistan’s soil. The two major regional rivers are the Amu Darya (darya is river in the Turkic language) and the Syr Darya. The former is about twice the size of the latter with the Amu Darya carrying about 70 km3 per year on average. The Amu Darya begins in the Pamirs and flows through Tajikistan and Afghanistan before it starts its decent toward the sea, passing through Turkmenistan and Uzbekistan. The Syr Darya also starts in Tajikistan and Kyrgyzstan and passes to the sea through a long stretch of Kazakhstan territory. Aralsk in Kazakhstan and Myunak in Uzbekistan were major fishing ports in the Aral Sea supporting into the 1960s a fishing sector of about 60,000 workers. In fact, there is a third major river in Central Asia, the Karakum Canal. This is in essence a manmade river, much of which is an unlined canal dug out of the desert sands, the construction of which began in the mid-1950s. It was designed to bring water to the least populated, most desertified country of the five Soviet Republics, Turkmenistan. It was over 1,000 km long and in recent years was extended about 300 additional km by the late president Niyazov. The demise of the Aral Sea did not occur overnight, but it did not take centuries either. It happened in a period of four to five decades. The dis- cussions about whether to exploit the sea’s waters took a bit longer than v vi FOREWORD did the sea’s recent decline. In 1908 Russian scientists first spoke of tapping the sea’s waters for “useful” purposes (read that as using the water for purposes suited to the needs of the Russian Empire). It was in the 1950s that Soviet leaders decided to sharply expand cotton production in the basin which required a major increase in diversions from the regions two major rivers. In that decade plans were developed that, around 1960, put into practice by the Soviet Politburo in the Kremlin sought to double the amount of hectares planted for cotton production. It was at about 4 million hectares then and was planned to go to about 8 million hectares devoted to cotton production. Hence, the necessity of increasing diversions from the rivers that fed the sea. After 1960, increasing amounts of water were diverted from the Amu Darya and the Syr Darya primarily in order to increase cotton production. Cotton has been the major crop in Central Asia, as the climate and soils were perfect for it. The missing ingredient in this equation was water. The rate at which diversions were made up to the 1950s was apparently below a threshold of adverse impacts on streamflow into the sea. Aside from its normal annual, decadal and other time scale fluctuations, human activities began to impinge on the quantity reaching the sea in the 1950s. The drying out of the Aral Sea turns out to be a perfect example of a “creeping” environmental change. These are environmental changes that are low grade, incremental but cumulative over time for which no obvious thresholds (step-like or irreversible change) can be identified in advance of crossing that threshold. Such changes almost always become creeping environmental problems (or CEPs), if not crises, which then demand the full attention of policy makers from the local to the national level. The Aral Sea was once the world’s fourth-largest inland sea. Its surface area once measured 66,100 km2 (25,521 square miles). Its problems began in the 1960s and 1970s with the diversion of the main rivers that feed it. By 1987, the Aral Sea had lost about 60% of its volume, its depth had dropped by 14 m (45 ft), and its salt concentration had doubled, killing the commercial fishing industry. Wind storms carried toxic dust onto farms a few hundred kilometers downwind, transporting fine grains of pesticide- and herbicide-laden dust that had been deposited for decades on the exposed sea floor. Life expectancies in the districts near the sea are significantly lower than in surrounding areas. The sea is now a quarter of the size it was 50 years ago and has broken into several parts, the North Aral Sea and the South Aral Sea (which is nearly separated in to two parts). Re-engineering a barrier to separate the Little (North) Aral from the Big Aral has served to retain water in the North Aral Sea. FOREWORD vii The science related to the Aral Sea is actually quite easy to understand, as complex as its components and their interactions might be. Many studies over at least half a century have provided researchers with considerable amounts of data relating to the climate, water and soils. The hydrological balance is known as are the many ways that settlements have interfered with or disrupted it. Clearly there is more water leaving the Aral Sea than is entering it (through land surface and sea water evaporative processes and water diversion to an adjacent basin). Cotton has been blamed for the demise of the sea and the poisoning of the water and agricultural lands. Fertilizers, herbicides and pesticides were applied to the cotton fields in great amounts, based on the assumption that if a small amount did some good than a lot would do even greater good for cotton production. It was revered as a crop and for the high level of pro- duction in the region. Little political attention was paid, however, to the environmental costs associated with cotton production. Quotas set in Moscow drove regional political leaders and collective farm managers to push hard on the workers to meet the unrealistic quotas, quotas that were often met only on papers sent back to Moscow. There are now many documented accounts about how the cotton production statistics were manipulated to please the Politburo thousands of kilometers away from Central Asia. To be fair to policy makers, the problems related to the Aral Sea were not the only ones these leaders had to face. Recall that the sea had been dropping slowly over time and not changing in notably sharp, step-like increments. These leaders have had to juggle many issues at the same time. The issues noted in the following list are meant to be illustrative and are not presented in order of priority. Under “normal” conditions, the five Central Asian Basin states (and Afghanistan) operate in a multi-stressed environment. Diverted streamflow Pesticide & fertilizer use Declining water quantity Declining water quality Shortened life expectancy Ethnic conflicts Rapid sea level drop Contaminated aerosols Loss of biological productivity Dust storms Loss of biological diversity Karakum Canal Loss of wildlife and forests Five competing nations Islamic fundamentalist threat Terrorist groups Upstream-downstream issues Authoritarian regimes Oil & gas haves vs. have-nots Global warming Hotter summers, colder winters Loss of cultural heritage Admittedly, it is easy to sit in an armchair far away from Central Asia and advise the leaders of the Central Asian republics about the need to break their dependence on cotton or to use water more efficiently. It is also viii FOREWORD easy to tell them that they must cooperate on issues related to the efficient management and use of water resources and related water supply issues. But to make the needed drastic changes is much easier said than done. The contributions to this volume represent sincere research efforts to improve the understanding of how the sustainability of Aral Basin ecosystems, water resources, soils, and human activities has each been undermined not precipitously but slowly over time. And, as creeping (slow onset, incremental but cumulative over time) as has been the widespread degradation through- out the basin, likely as creeping will be its rehabilitation. Sustained monitoring of environmental and social change and continued research to identify poten- tial pathways to rehabilitate local and regional ecosystems and societies are a necessity if leaders in the region have any hope for long term economic progress. Michael Glantz Boulder, Colorado, June 2008 PREFACE Central Asia is largely arid and semi-arid and therefore very sensitive to environmental perturbations. Recent changes in social structures, accom- panied by regional climate change, have caused substantial environmental changes leading to security concerns in the region. Water levels in the major rivers of the region, the Amu Darya and Syr Darya have been reduced significantly due to overdraws along their courses from intensified irrigation and industrial use. Soil salinization problems have worsened due to increased surface evaporation. Snow covers and glaciers have receded due to regional climate change and thus reduced freshwater supplies to the region. As a result, the local economy has been significantly impacted to the extent that the potential for social unrest is a big concern. There is a need to develop new technologies and adaptation strategies to mitigate these environmental problems and cope with continued environmental change. In order to address these issues, regional experts from 13 countries gathered together for an international workshop sponsored by the NATO Science for Peace and Security Program in Tashkent, October 1–5, 2007, to share information about ongoing efforts in the region. Their areas of expertise included climate science and modeling, land use/cover change, biogeochemical processes, socioeconomics, resource management, and geo- spatial technologies. Specific science questions the experts addressed were: 1. What are the emerging environmental and societal issues of the region? 2. What are the state-of-the-art research methodologies used in address- ing these issues? 3. What technologies are available to help mitigate the environmental and societal issues of the region? 4. Finally, what institutional policies should be implemented to miti- gate the emerging environmental issues? This book highlights research efforts that address one or more of these questions using case studies as a demonstration of mitigation and adaptation strategies for environmental problems in Central Asia. It is hoped that these studies will serve as examples that can be scaled up and transferred to deci- sion makers in an effort to implement effective policies and management practices. The editors are grateful for the contributions of the authors, both to the workshop and to this book. We would like to give our sincerest thanks as well to the dedicated staff members in Uzbekistan who overcame numerous ix x PREFACE logistic challenges to make this workshop possible. Organizational support for this workshop was provided by the Scientific-Research Department of Ecology at the National University of Uzbekistan, the Heat Physics Depart- ment of the Uzbek Academy of Sciences, and the Center for Global Change and Earth Observations at Michigan State University.
