Full Text Available This is the first study of the role Soviet diplomats and representatives of the Communist International (Comintern played in the Soviet-Tuvan relations during the first decade after the emergence of the young Tuvan state – People’s Republic of Tuva (1920s. From representing the interests of a small military mission, the Soviet diplomatic office in Tuva evolved into a full-scale embassy of the Soviet state. Its history clearly falls into two stages: from early 1920s to 1927 Soviet mission members largely abstained from interfering into PRT’s internal issues, but subsequently they started actively promoting the left wing of Tuvan People Revolutionary Party, which contributed to its accession to power. The Soviet state began to act as PRT’s patron on the international arena. This policy of support and custody was in accordance with Article 2 of PRT’s constitution. Using documentary sources, this article traces the appointments and transfers of a number of Soviet diplomatic officers and consuls (F.G. Falsky (Falkovsky, I.A. Chichayev, F.F. Razumov, A.G. Starkov, as well as Comintern representatives (I.G. Safyanov, B. Tsivenzhapov, V. Borovikov, A.M. Amur-Sanan, S.A. Natsov, V. Machavariani, V.A. Bogdanov. In the duopoly of consuls and Comintern representatives, the former dominated at the earlier stages, but after the defeat of Chinese communists in 1927 the Soviet leaders thought that Socialist transformations in Mongolia in Tuva should be sped up.

Forest fires resulting from long periods of drought cause extensive forest ecosystem destruction and can impact on the carbon balance and air quality and feed back to the climate system, regionally and globally. Past fire frequency is reconstructed for Tuvan Scots pine stands using dendrochronology and statistics. Central Tuvan Scots pine (Pinus sylvestris) stands are subject to annual fire regimes; however high intensity fires are rare but they are responsible for most of the damage. Low, medium, and high severity fires have shaped the multi-story Scots pine communities, locally and regionally. Fire type and frequency are directly related to weather and climate and are also dependent on anthropogenic influences. The primary dry period, which promotes fire ignition and spread, in Tuva occurs in April and May. In some years, the precipitation deficit combined with high air temperatures induces long periods of drought. Unlike the typical surface fire regime, forest fires that burn during these extreme droughts often become crown fires that result in substantial forest damage and carbon release. The mean fire interval (MFI) is found to be 10.4 years in Balgazyn stands, and the landscape-scale MFI is 22.4 years. High severity, stand-replacing crown fires have a longer MFI. The warmer and dryer weather that is predicted by global climate models is evident in Tuva, and we believe that these changes in weather and climate have resulted in increased fire intensity and severity, rather than fire frequency in the Tuvan region.

Soil salinization in different natural zones of intermontane depressions in Tuva

Science.gov (United States)

Chernousenko, G. I.; Kurbatskaya, S. S.

2017-11-01

Soil salinization features in semidesert, dry steppe, and chernozemic steppe zones within intermontane depressions in the central part of the Tuva Republic are discussed. Chernozems, chestnut soils, and brown desert-steppe soils of these zones are usually nonsaline. However, salinization of these zonal soils is possible in the case of the presence of salt-bearing parent materials (usually, the derivatives of Devonian deposits). In different natural zones of the intermontane depressions, salt-affected soils are mainly allocated to endorheic lake basins, where they are formed in places of discharge of mineral groundwater, and to river valleys. The composition and content of salts in the natural waters are dictated by the local hydrogeological conditions. The total content of dissolved solids in lake water varies from 1 to 370 g/L; the water is usually of the sulfate-chloride or chloride-sulfate salinity type; in some cases, soda-sulfate water is present. Soil salinity around the lakes is usually of the chloride-sulfate-sodium type; gypsum is often present in the profiles. Chloride salinization rarely predominates in this part of Tuva, because chlorides are easily leached off from the mainly coarse-textured soils. In some cases, the predominance of magnesium over sodium is observed in the composition of dissolved salts, which may be indicative of the cryogenic transformation of soil salts. Soda-saline soils are present in all the considered natural zones on minor areas. It is hardly possible to make unambiguous statements about the dominance of the particular type of salinity in the given natural zones. Zonal salinity patterns are weakly expressed in salinization of hydromorphic soils. However, a tendency for more frequent occurrence of soda-saline soils in steppe landscapes and chloride-sulfate salinization (often, with participation of gypsum) in the dry steppe and semidesert landscapes is observed.

The Central Asian region, which encompasses Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan and Kyrgyzstan, is an interesting geographic region with a rich history dating back to the Silk Road, Mongol conquests and expansion of the Russian Empire. However, from a public health viewpoint, the Central Asian region is under-investigated, and many public health challenges exist, as countries of Central Asia inherited the centralised medical systems practiced in the Soviet Union, and are currently undergoing rapid transitions. A large number of low and middle-income countries around the world, including countries of Central Asia, face a double burden of chronic and infectious disease. This essay focuses on the exploration of the most important public health challenges in the Central Asian region, including limited scientific productivity, the double burden of chronic and infectious disease, the need for healthcare reform and the reduction in care variation. Central Asia has a large number of medical schools, medical centres, and emerging research institutes that can be used to foster a change in medical and public health practice in the region.

Paleoclimate records of effective moisture (precipitation minus evaporation, or P-E) show a dry (low effective moisture) period in mid-latitude arid/semi-arid central Asia during the early Holocene (11,000-8,000 years ago) relative to the middle and late Holocene, in contrast to evidence for greater-than-present precipitation at the same time in the south and east Asian monsoonal areas. To investigate the spatial differences in climate response over mid-latitude central Asia and monsoonal Asia we conducted a series of simulations with the Community Climate System Model version 3 coupled climate model for the early, middle and late Holocene. The simulations test the climatic impact of all important forcings for the early Holocene, including changes in orbital parameters, the presence of the remnant Laurentide ice sheet and deglacial freshening of the North Atlantic. Model results clearly show the early Holocene patterns indicated by proxy records, including both the decreased effective moisture in arid central Asia, which occurs in the model primarily during the winter months, and the increase in summer monsoon precipitation in south and east Asia. The model results suggest that dry conditions in the early Holocene in central Asia are closely related to decreased water vapor advection due to reduced westerly wind speed and less evaporation upstream from the Mediterranean, Black, and Caspian Seas in boreal winter. As an extra forcing to the early Holocene climate system, the Laurentide ice sheet and meltwater fluxes have a substantial cooling effect over high latitudes, especially just over and downstream of the ice sheets, but contribute only to a small degree to the early Holocene aridity in central Asia. Instead, most of the effective moisture signal can be explained by orbital forcing decreasing the early Holocene latitudinal temperature gradient and wintertime surface temperature. We find little evidence for regional subsidence related to a stronger summer Asian

The Islamic factor on the territory of Central Asia

Full Text Available The countries of Central Asia belong mainly to Turkish speaking area, thus the Islamic religion and culture. Islam began to spread across this territory through new cultural contacts around 700 AD as a result of conquest, distant trade and missionary activities. Tendencies of Russia and Turkey towards Central Asia are increasing the danger of the conflict outbreak in the critical areas of the region. From the early 2000s until now, Central Asia has become much more divided interethnically than it was during the Soviet period. At the end of 1970s the establishment of new Islamic Movements began. The most active movements today are: Hizb Ut-Tahrir, the Islamic Movement of Uzbekistan and the Islamic Renaissance Party of Tajikistan. Extremism and radicalism are the most active, but also the smallest part of the Islamic movement in the whole world, including Central Asia. These movements have different tactics that are manifested in the form of various methods and means used for achieving objectives.

Prospects for a nuclear-weapon-free zone in Central Asia

International Nuclear Information System (INIS)

Potter, W.C.

1997-01-01

This paper examines the concept of a Nuclear-Weapon-Free Zone (NWFZ) as an approach to nuclear nonproliferation with special reference to Central Asia . 20 More specifically, it describes the evolution of a NWFZ in the region, the potential benefits of a zone, the principal obstacles in the path of its implementation, and the practical steps that need to be taken if a NWFZ in Central Asia is to be realized. The paper concludes that a NWFZ in Central Asia, as with prior NWFZ, would likely lead to advances in the application of an important nonproliferation approach. One innovative aspect of the zone in Central Asia might be its treatment of environmental issues. Although it will not be a simple process to rally support from all of the P-5 states for a new NWFZ, all countries of Central Asia - as well as global community of nations - should profit from creation of a zone which reinforces the international nonproliferation regime improves prospects for political and economic stability in a region of growing importance

Full Text Available This is a study of author-performed song in Tuva, the history of which begins when the People’s Republic of Tuva was declared in 1921. This crucial moment in the history of the region, which bore a strong influence of the October Revolution in Russia and of the following years of social change, had a profound impact on songwriting in the 1920s. The songs expressed gratitude to the October Revolution, Lenin and the Russian people for helping Tuvans get rid of the socially oppressive system (“The Glorious International”, “Freedom from Torment”, “The Great River”, “The Emergency Session of the Khural”, “No More Oppression”, etc.. New songs glorified such iconic features of new life as the first schools, the birth of national literature and the new system of writing, the change in attitude to women, the rise of the new generation of authors, the construction of a new automobile road, etc. In the 1930s further socioeconomic transformation gave rise to songs like “I Am a Kolkhoz Member”; “The Tractor Driver”, “The Propagandist”, “The Beautiful Soviet Land”, etc. By the end of the 1930s Tuva got its first amateur composers and author-performed songs. The arrival of theater, dance and music professionals from the USSR at the beginning of the 1940s at the bequest of PRT’s government led to a sea change in professionalization of Tuvan performing arts. In 1951 A. Chyrgal-ool became the first Tuvan student to join a conservatoire in Kazan which he graduated from in 1957. His works composed in 1950s marked a new stage in the rise of professional music in the region. Thus Tuvan song art featured almost the same trends and developments as most other ethnic groups in the Soviet Union.

Central Asia is a typical arid area, which is sensitive and vulnerable part of climate changes, at the same time, Central Asia is the Silk Road Economic Belt of the core district, the warm-humid climate change will affect the production and economic development of neighboring countries. The average annual precipitation, average anneal temperature and evapotranspiration are the important indexes to weigh the climate change. In this paper, the annual precipitation, annual average temperature and evapotranspiration data of every pixel point in Central Asia are analyzed by using long-time series remote sensing data to analyze the trend of warm and humid conditions. Finally, using the model to analyzed the distribution of warm-dry trend, the warm-wet trend, the cold-dry trend and the cold-wet trend in Central Asia and Xinjiang area. The results showed that most of the regions of Central Asia were warm-humid and warm-dry trends, but only a small number of regions showed warm-dry and cold-dry trends. It is of great significance to study the climatic change discipline and guarantee the ecological safety and improve the ability to cope with climate change in the region. It also provide scientific basis for the formulation of regional climate change program. The first section in your paper

Oil and the geopolitics of Central Asia: A "new 'great game'"?

Science.gov (United States)

Al-Sati, Saud M.

The nineteenth century rivalry between the Russian Empire and Great Britain over Central Asia, known as the "great game," was triggered by the quest for power and dominance. This study revisits Sir Halford Mackinder's thesis, which viewed the "heartland," consisting of Russia and Central Asia, as being crucial for international politics. It also discusses the influence of Mackinder's ideas on twentieth century geopolitical thinking. The study also examines the common assumption that the new "great game" in Central Asia is evolving around the exploitation of energy resources, and analyzes the consequences of this new factor for the geopolitical significance of the region. The landlocked nature of the Central Asian countries makes it necessary for them to rely on their neighbors for the export of oil and gas to international markets. Thus, the political and economic interests of Russia, Iran, and Turkey motivate them to compete with each other for export routes through their territories. This study also shows that the estimates of Central Asian proven oil reserves are characterized by considerable ambiguity. Estimates vary from seven to twenty-two billion barrels. Despite the fact that these proven oil reserves are limited compared to those of other regions, such as the Middle East, continued exploration is compatible with the Western strategy of energy resource diversification. Another primary aim of American involvement is to prevent the reintegration of Central Asia into the Russian federation and to block Chinese influence in Central Asia. This study reveals that realities in today's Central Asia are different from those of the nineteenth century. Central Asia now consists of independent countries; the competing powers have changed, with the exception of Russia; and oil has emerged as a new factor. However, the perpetual quest for power and dominance that marked the historical "great game" is still at work in the last decade of the twentieth century. Finally, the

Women’s world in contemporary Tuva

Full Text Available The article examines the ethnodemographic and ethnosocial position of ethnic Tuvan women in Tuva. Our analysis makes use of the concept of ‘women’s world’ which is actively used by researchers in the current state of increasing gender asymmetry. We treat ‘women’s world’ as a holistic worldview of women united by single values, attitudes and practices of living. The contemporary shift in traditional male and female roles leads to blurring the boundaries between male and female functions and responsibilities. The crisis of family values has been brought about by the market economy and the overall social and economic situation in the country. In contemporary society women find themselves involved in public life, which limits her abilities in the sphere of family relations and marriage. To analyze the values, attitudes and practices which are important for Tuvan women, we have held an opinion poll of 250 women respondents in Tuva in spring 2015. Tuvan society has always viewed family as the supreme value, and still does. When choosing a partner (which a woman is free to decide for herself, Tuvan women look for a caring, understanding, kind, educate, loving partner, with no pernicious addictions. Three is the ideal number of children in the family, although most families have only 1 or 2. Women of elder generations would typically have a bigger number of children. Younger generations are known for high divorce rate. One of the most important reasons for divorce is the urgent need for satisfying the family’s material needs. A contemporary Tuvan woman combines in her social position both traditional and new functions, trying to uphold the values of family life, high level of welfare and the opportunity for self-actualization. Due to this combination, Tuvan society has a relatively high (if compared to other regions level of reproductive goals, which means that a large part of respondents plans to have many children. However, the unstable

Central Asia is one of the regions that suffer the most prominent transboundary water and energy problems in the world. Effective transboundary water-energy resource management and cooperation are closely related with socioeconomic development and stability in the entire Central Asia. Similar to Central Asia, Northwest China has an arid climate and is experiencing a water shortage. It is now facing imbalanced supply-demand relations of water and energy resources. These issues in Northwest China and Central Asia pose severe challenges in the implementation of the Silk Road Economic Belt strategy. Based on the analysis of water and energy distribution characteristics in Central Asia as well as demand characteristics of different countries, the complexity of local transboundary water problems was explored by reviewing corresponding historical problems of involved countries, correlated energy issues, and the evolution of inter-country water-energy cooperation. With references to experiences and lessons of five countries, contradictions, opportunities, challenges and strategies for transboundary water-energy cooperation between China and Central Asia were discussed under the promotion of the Silk Road Economic Belt construction based on current cooperation conditions.

The extent to which climate variability in Central Asia is causally linked to large-scale changes in the Asian monsoon on varying timescales remains a longstanding question. Here we present precisely dated high-resolution speleothem oxygen-carbon isotope and trace element records of Central Asia's hydroclimate variability from Tonnel'naya cave, Uzbekistan, and Kesang cave, western China. On orbital timescales, the supra-regional climate variance, inferred from our oxygen isotope records, exhibits a precessional rhythm, punctuated by millennial-scale abrupt climate events, suggesting a close coupling with the Asian monsoon. However, the local hydroclimatic variability at both cave sites, inferred from carbon isotope and trace element records, shows climate variations that are distinctly different from their supra-regional modes. Particularly, hydroclimatic changes in both Tonnel'naya and Kesang areas during the Holocene lag behind the supra-regional climate variability by several thousand years. These observations may reconcile the apparent out-of-phase hydroclimatic variability, inferred from the Holocene lake proxy records, between Westerly Central Asia and Monsoon Asia.

Similar speleothem δ18O signals indicating diverging climate variations in inland central Asia and monsoonal south Asia during the Holocene

High-resolution and precisely dated speleothem oxygen isotope (δ18O) records from Asia have provided key evidence for past monsoonal changes. It is found that δ18O records of stalagmites from Kesang Cave (42°52'N, 81°45'E, Xinjiang, China) in inland central Asia were very similar to those from Qunf Cave (17°10'N, 54°18'E, southern Oman) in South Asia, shifting from light to heavy throughout the Holocene, which was regarded as a signal that strong Asian summer monsoon (ASM) may have intruded into the Kesang Cave site and/or adjacent areas in inland central Asia to produce heavy rainfall during the high insolation times (e.g. the early Holocene). However, this is in contrast to conclusions based on other Holocene proxy records and modeling simulations, showing a persistent wetting trend in arid central Asia during the Holocene with a dryer condition in the early Holocene and the wettest condition in the late Holocene. With an analysis of model-proxy data comparison, we revealed a possible physical mechanism responsible for the Holocene evolution of moisture/precipitation in Asian summer monsoon (ASM)-dominated regions and that in the inland central Asia. It is revealed that a recurrent circumglobal teleconnection (CGT) pattern in the summertime mid-latitude circulation of the Northern Hemisphere was closely related to the ASM and the climate of inland central Asia, acting as a bridge linking the ASM to insolation, high-latitude forcing (North Atlantic sea surface temperature (SST)), and low-latitude forcing (tropical Ocean SST). Also, the CGT influence speleothem δ18O values in South Asia via its effect on the amount of precipitation. In addition, the moisture source from the Indian Ocean is associated with relatively high δ18O values compared with that from the North Atlantic Ocean, leading to increased precipitation δ18O values. Hence, the CGT has probably been the key factor responsible for the in-phase relationship in speleothem δ18O values (Kesang Cave

MSVI was present in 1,178,000 (95% CI 772,000 to 2,243,000) people in the Central Asia, and in 71,600,000 (95% CI 57,600,000 to 92,600,000) people in South Asia. Women were generally more often affected than men. The leading causes of blindness (cataract) and MSVI (undercorrected refractive error) did not change from 1990 to 2010. The prevalence of blindness and MSVI in South Asia is still three times higher than in Central Asia and globally, with women generally more often affected than women. In both regions, cataract and undercorrected refractive error were major causes of blindness and MSVI.

Full Text Available Changes in the system of value orientations and cultural preferences in post-Soviet Russia are of highest importance for contemporary researchers. This article examines the value orientations of the residents of the Republic of Tuva (a constituent subject of Russian Federation both in toto and by generation and along the urban/rural divide. Our analysis utilized the outcomes of our empirical studies titled “The current state of sociocultural institutions in the Republic of Tuva and their role in preventing social problems” (2011 and “The rural culture of the Republic of Tuva” (2011-2012. I am grateful to students of the Tuva Branch of East Siberian State Academy of Culture and Fine Arts for their aid in conducting the study. The study showed that the system of value orientations in Tuva features certain distinctions between those of urban and rural residents, and along the generational divide. The urban population’s vital values are health, personal security and success (for the elder generation and health, money and personal success (for the younger generation. Among the social values the elder generations most frequently name respect from others, integrity, good family relations, while the younger generation focuses on respect from others, good friendship and integrity. Rural population places family and health above everything else. Studying leisure time of the urban population in Tuva showed that the list of top activities includes spending time with friends and/or family, watching TV and a day outdoors. The outcomes of our study do not completely match the hierarchy of leisure time activities in other regions of Russia and the national average. There is a certain danger in contemporary urban environment’s trend towards leaning down the variety of leisure activities. Our study showed that the urban and rural populations have almost identical TV watching habits, with the majority preferring newscasts, music shows and crime reports

Regional integration in Central Asia: From knowing-that to knowing-how

Ulugbek Azizov

2017-07-01

Full Text Available The paper examines regional integration in Central Asia in the context of two types of knowledge, that is, knowing-that and knowing-how. While knowing-that prioritizes representational (i.e. “talking” practices of actors to explain region-building processes, knowing-how focuses on non-representational (i.e. “doing” practices. The article demonstrates that the orthodox scholars, who deal with the region of Central Asia, mostly employ knowing-that to explain region-building processes. The article criticizes knowing-that, assuming that this type of knowledge limits our understanding with regard to how regions get their boundaries and symbolism in the era of globalization and standardization of sectoral activities. Thus the article develops and introduces an alternative knowing-how framework to better understand the region-building processes in Central Asia and beyond it.

US POLICY TOWARDS CENTRAL ASIA UNDER TRUMP

Lance Alred

2017-10-01

Full Text Available U.S. policy faces numerous challenges in Central Asia, such as the decreasing U.S. military and economic resources in the region; Russian and Chinese hostility to a long-term U.S. military presence in Eurasia; restrictions on religious and other freedoms due partly to counterterrorism concerns; limited U.S. involvement in the region compared to other external players (like Japan as well as Russia and China; an undeveloped U.S. policy regarding regional multinational institutions; and the indifference and ignorance of U.S. business toward regional commercial opportunities beyond the energy sector. However, advocates of “America First” in the Trump administration do not see these threats as sufficiently serious to garner U.S. military intervention beyond occasional training, equipping, and intelligence sharing. Terrorism, drug trafficking, economic isolation, and human rights restrictions in Central Asia do not present an immediate existential threat to the United States, sowing ambivalence over the future of U.S. foreign policy in the region.

The Russian State, Lenin and the Central Asia

Full Text Available Central Asian nations faced a challenge of state-building objectives after the collapse of the USSR. However, it was a complicated task, because those nations were parts of the Russian and, lately, the Soviet state. State-building objectives include the creation of new historical narrative. Central Asia is now experiencing the process that is called "national novel" in the Western European historiography. Central Asian national variants of historical narratives serve as a conceptual basis for the writing of school and university textbooks. The introduction of ideological constructs through the education system is carried out everywhere. However, it is important to note that inevitable ideological indoctrination should not undermine scientific essence of textbooks. Politics of nation formation and the preservation of its identity is implemented and fostered by states carefully as well as clumsy. There is no doubt that there is an inevitable and practical need for constructing "national novel" in the new states. But historical politics should not ignore some of the methodological and at the same time mental traps that exist in the field of studying the history of the peoples of Central Asia in the period of the Russian Empire.

“URIANKHAI ISSUE”IN FOREIGN POLICY OF RUSSIA IN EARLY 20TH CENTURY AND THE PROBLEM OF FOREIGN STATES’ PARTICIPATION IN IT

В А Василенко

2017-12-01

Full Text Available The article presents the analysis of the participation of foreign countries in solving the problems related to the management of domestic and foreign policy in Tuva in the ear-ly twentieth century.The problem of determining the legal and political status of Tuva and its territorial jurisdiction is traditionally bound in domestic and foreign historiography with the words “Uriankhaiissue”. The latter, as a rule, is considered in the context of rivalry be-tween Russia, China and Mongolia - the countries of the “Central Asian triangle”. The author pays attention to the interests of other countries, including Japan and the coun-tries of Western Europe, in this region. There has been conducted a generalized analysis of the information relating to the presence of Western industrial capital inTuva, shows the nature of the relations between the European entrepreneurs from Russia, China and Tuva authorities. The article provides the detailed facts of the presence of various groups of foreign citizens in the province in the period of the protectorate. In the context of the analysis of the general geo-political situation in Central Asia, the author describes the actions of the Russian authorities against foreign troops, including the methods and forms of work in that direction. The author comes to the conclusion that, despite the use of exclusively peaceful measure-sagainst foreign troops in Tuva, the local authorities sought to prevent any actions aimed at undermining the Russian positions in the region. For this reason, depending on the geopolitical situation in Tuva, the regime of stay of foreigners, issuance of permits softened or hardened. The author concludes the study with the description of the events of the 1920s, the time when there was a change of concept relations with foreign states due tothe Bolsheviks’ coming to power.

Oil sector developments: Russia, Azerbaijan and Central Asia

International Nuclear Information System (INIS)

Ebel, R.E.

1997-01-01

The level of resource development in Russia, Azerbaijan and in the countries of Central Asia was discussed. The resources of crude oil and natural gas in the area are considered more than sufficient to support any reasonable expansion for the foreseeable future and this should mean higher exportable surpluses. The collapse of the Soviet Union resulted in the emergence of 15 sovereign and independent nations, collectively known as the Commonwealth of Independent States (CIS). The end of the cold war opened the CIS's oil sector to foreign investors. However, access to these markets has been blocked by the physical isolation of Azerbaijan and Central Asia. According to forecasters, by the year 2005, the annual oil production of the CIS shall reach 7.9 million barrels per day, approximately 11.3 per cent higher than in 1996. Natural gas production is expected to increase by about 30 per cent to 900 billion cubic meters per year. Western capital will be key to the future of resource development in Azerbaijan, Kazakhstan, and Turkmenistan. It was suggested that by 2010, the exportable oil from the Caspian Sea and Central Asia will represent 3 to 4 per cent of world oil supply. This projection emphasizes the fact that this new oil would be in addition to, and not in place of oil from the Persian Gulf. Some of the economic and political problems that have had a delaying effect on the development of pipelines through these regions were also reviewed

China, Russia and Central Asia: The energy dilemma

Energy Technology Data Exchange (ETDEWEB)

Bergsager, Henrik

2012-07-01

How China will satisfy its rising energy demand will have impact on the availability and market price of energy resources such as oil and gas, but also on foreign policy. Of special interest is the role of rising neighboring countries and region; Russia and Central Asia countries, who can supply China by way of pipelines. In this paper important factors influencing Chinese energy decision-making are discussed, with a particular focus on energy investments abroad. The state capitalism framework is used to explain the long-term policies of Chinese energy investments as well as discuss the importance of State-Owned Enterprises and National Oil Companies to the Chinese economy. On this background the energy relations between Russia, China and other Central Asia states is discussed. The main focus is on the influence Chinese Energy Based Loan (EBL) agreements have on the Chinese presence both economically and politically in the region. The objective is to present the current situation and outlook for Sino-Russian-Central Asian energy relations as well as the economic implications a closer Chinese presence could have for the region. China's EBLs with Central Asian countries illustrate the preferred Chinese approach in expanding trade relations and should be considered as important examples for future bilateral agreements.(Author)

Soft Power in Central Asia: Actors and Its Activities

Directory of Open Access Journals (Sweden)

Marina M. Lebedeva

2014-01-01

Full Text Available Article considers theoretical aspects of soft power concept and its use by various actors in Central Asia. It is noted that scholars as well as practitioners are paying insufficient attention to such key concepts position J. Nye, as an attraction. As a result the efficiency of the use of soft power is significantly reduced. It also shows that the attractiveness is not a universal characteristic. For this reason, attractiveness and hence soft power of different actors are different and aimed at different segments of the population. These differences lead to competition of actors, but they do not reduce interaction in the region to zero-sum game. Specific forms and directions of the soft power of Russia, the U.S., the EU and China in Central Asia are discussed. The article emphasizes that the Central Asian states are not just recipients of soft power of external actors, but also themselves form behavioral strategies that are attractive to others.

What caused the cool summer over northern Central Asia, East Asia and central North America during 2009?

Cool and wet weather conditions hit northern Central Asia, East Asia and central North America during the 2009 summer in concert with a strong jet stream and a prominent meandering upper-level circulation in the Northern Hemisphere mid-latitudes despite the fact that the year 2009 is the fifth warmest year globally in the modern record. It is found that the conspicuous atmospheric variability in the entire Northern Hemisphere mid-latitudes during the summer of 2009 was caused by a combination of teleconnections associated with significant tropical thermal forcings, strong polar forcing, and interaction between high-frequency weather events and climate anomalies. The strong negative circumglobal teleconnection pattern associated with the deficient Indian summer monsoon rainfall and developing El Niño condition was the major contributor to the cool and wet summer in June. On the other hand, the July weather conditions were attributable to the high-latitude impact of the unprecedented negative Arctic Oscillation, together with the Rossby wave response to the subtropical heating generated by convective activities over the Western North Pacific summer monsoon region. It is also noted that enhanced storm track activity and frequent cold surges from high-latitudes may have played a role in the cool and wet summer over the regions of interest. (letter)

Central Asia in the Iranian geopolitical imagination

Directory of Open Access Journals (Sweden)

Edward Wastnidge

2017-02-01

Full Text Available This article charts Iran’s relations with Central Asia following the break-up of the Soviet Union in 1991. This event gave Iran a new set of neighbours to the north, and this came at a time when Iran was undergoing changes in the direction of its foreign policy from radical idealistic goals, such as the export of the Islamic Revolution, to more pragmatic aims, including giving priority to its own national interests and pursuing good neighbourly relations. Since 1991, Iran has attempted to develop relations towards the Central Asian states, both bilaterally and through various regional fora. Iran’s actions have been based, in part, on a greater commitment to regionalism that has been evident in Iranian foreign policy since the early 1990s. This has focused on cultivating economic, infrastructural and cultural links with the region, rather than any form of ideological crusade, and has helped reduce Iran’s international isolation. Following a historical contextualisation and explanation of the place that the lands of Central Asia hold in the Iranian geopolitical imagination, the article explores the key concerns of Iran in the region. It will examine Iran’s position on what it perceives as being the key issues shaping its Central Asian diplomacy, namely regional economic cooperation, pipeline politics, the status of the Caspian Sea, security cooperation and cultural diplomacy. This provides a revealing case study of how Iran perceives itself as a vital player in the region, seeking to emphasise the benefits of its geostrategic location, relative stability, and increasing international role following the nuclear deal.

2014-01-01

Based on NOAA/AVHRR NDVI biweekly time-series data, the start and end of the growing season of Central Asia from 1982 to 2006 were estimated. Trend analysis results indicate an earlier green-up and a later dormancy over the entire area during the study period. For seven main vegetation types, the largest advance of greenup onset (0.597 days/year) occurs in cropland and the longest delay of dormancy (1.109 days/year) in open shrubland. The smallest advance (0.164 days/year) occurs in evergreen needleleaf forest and delay (0.443 days/year) in crop/natural vegetation mosaic. These results imply enhanced vegetation activity in the Central Asia region over last decades

Toward a cross-border early-warning system for Central Asia

Directory of Open Access Journals (Sweden)

Jacek Stankiewicz

2015-04-01

Full Text Available Rapidly expanding urban areas in Central Asia are increasingly vulnerable to seismic risk; but at present, no earthquake early warning (EEW systems exist in the region despite their successful implementation in other earthquake-prone areas. Such systems aim to provide short (seconds to tens of seconds warnings of impending disaster, enabling the first risk mitigation and damage control steps to be taken. This study presents the feasibility of a large scale cross-border regional system for Central Asian countries. Genetic algorithms are used to design efficient EEW networks, computing optimal station locations and trigger thresholds in recorded ground acceleration. Installation of such systems within 3 years aims to both reducing the endemic lack of strong motion data in Central Asia that is limiting the possibility of improving seismic hazard assessment, and at providing the first regional earthquake early warning system in the area.

Water is an indispensable necessity of life for people in the whole world. In central Asia, water is the key factor for economic development, but is already a narrow resource in this region. In fact of climate change, the water problem handling will be a big challenge for the future. The regional research Network "Central Asia Water" (CAWa) aims at providing a scientific basis for transnational water resources management for the five Central Asia States Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan and Kazakhstan. CAWa is part of the Central Asia Water Initiative (also known as the Berlin Process) which was launched by the Federal Foreign Office on 1 April 2008 at the "Water Unites" conference in Berlin. To produce future scenarios and strategies for sustainable water management, data on water reserves and the use of water in Central Asia must therefore be collected consistently across the region. Hydro-meteorological stations equipped with sophisticated sensors are installed in Central Asia and send their data via real-time satellite communication to the operation centre of the monitoring network and to the participating National Hydro-meteorological Services.[1] The challenge for CAWa is to integrate the whole aspects of data management, data workflows, data modeling and visualizations in a proper design of a monitoring infrastructure. The use of standardized interfaces to support data transfer and interoperability is essential in CAWa. An uniform treatment of sensor data can be realized by the OGC Sensor Web Enablement (SWE) , which makes a number of standards and interface definitions available: Observation & Measurement (O&M) model for the description of observations and measurements, Sensor Model Language (SensorML) for the description of sensor systems, Sensor Observation Service (SOS) for obtaining sensor observations, Sensor Planning Service (SPS) for tasking sensors, Web Notification Service (WNS) for asynchronous dialogues and Sensor Alert Service

Ethnic entrepreneurship without migration: the cases of Tuva and Kalmykia

Svetlana P. Tyukhtenyeva

2018-06-01

When compared to ethnic entrepreneurs who migrate out of their region, their two counterparts in Tuva and Kalmykia find themselves in a much more advantageous social environment. Their projects follow within the course of ever intensifying national rebirth, but have to grapple with economic difficulties typical for agrarian regions which rely on animal farming. Also important for the success of the business is the personality factor, which comprises a whole host of identities – ethnocultural, gender, local, civic, and others, all of them informing the activity of the person. A drive towards variety is a common feature among ethnic entrepreneurs, which allows them to diversify their businesses. The very ethnicity of an entrepreneur can be seen as an asset, since it can improve their competitiveness.

Russian autonomous labor colony in the People’s Republic of Tuva as a unique case of Russian regionalism

Directory of Open Access Journals (Sweden)

Vladimir G. Dazishen

2016-09-01

Full Text Available The article examines the experience of Russian regionalism in mid-19th – early 20th century Tuva, which took shape of setting up a colony of Russian subjects and became one of the most powerful factors behind the declaration of the People’s Republic of Tuva. Russian Autonomous Labor Colony (RALC was established in early 1920s and lasted for 10 years as a unique political entity in the history of Russia. RALC was fully controlled by official representatives of the Soviet state. Its stable population of over 10000 was mainly involved in cattle breeding, agriculture, crafts and even trade. RALC had its own legislation which even provided for certain elements of statehood. It was allowed to create its own flag and emblem, control its budget, and had its own military unit. The land under use by the colonists was on official lease from the government of the People’s Republic of Tuva (PRT. Ethnic Russians with Soviet citizenship complied with the legislation of the RSFSR. RALC had its own court, with convicted criminals serving their sentence in the PRT. Both RALC and PRT passed through several stages of increasingly radical left-wing reforms, which gave Moscow a firm grip over the local political establishment. In the second half of the decade the sociopolitical structure that included the RALC started to crumble away. On May 24, 1932, the autonomy was abolished by the new USSR-PRT agreement that oversaw the transformation of the colony’s remnants into Committees of Soviet Citizens. The article introduces a number of unpublished or little-known documents from the state archives of Krasnoyarsk, Novosibirsk, Irkutsk and other cities of the Russian Federation.

Central Asia: A major emerging energy player in the 21st century

International Nuclear Information System (INIS)

Dorian, James P.

2006-01-01

Energy is the most abundant and valuable natural resource of Central Asia and northwest China and includes oil, gas, coal, electricity, and renewables. Kazakhstan has large reserves of oil and coal. Turkmenistan and Uzbekistan have significant reserves of gas. Kyrgyzstan produces significant amounts of hydroelectric power. Xinjiang, China has significant coal resources and an uncertain, although generally promising, potential for oil in the Tarim basin. These energy reserves form the basis for future economic growth and development in the region, and energy exports are beginning to generate important foreign exchange revenues. Although Central Asia enjoys vast energy development potential, there are obstacles to exploiting these resources, including limited infrastructure for transporting energy-notably oil and gas pipelines and electric transmission lines-in the region, political turmoil, payment difficulties, and inadequate energy policies. Despite these challenges, however, with appropriate government planning Central Asia is poised to become a significant world supplier of energy, especially in the oil and gas sectors, and the region is likely to diminish OPEC's influence of the global oil market over the long term.

The Geopolitics of Central Asia after the Annexation of Crimea in 2014

Directory of Open Access Journals (Sweden)

Razma Ainis

2015-12-01

Full Text Available The annexation of Crimea accomplished by Russia in 2014 is the event that stands out sharply in the context of post-Cold War international relations: it was the first time after the end of WWII in Europe that a part of the territory of a sovereign state was forcefully annexed. This means that the re-drawing of borders and revisionism are back in international relations as the principles and ways of policy making. It would be plausible to assume that the consequences of an event of such scale would be noticeable not only in its direct neighborhood but as well in more distant, though geopolitically sensitive contexts. The article explores the impact that Russia‘s Crimea campaign has had on the geopolitics of Central Asia and what consequences could be deemed plausible in the future. It is assumed that, due to the annexation of Crimea, international relations started polarizing around the two centers of power: the West and Russia. This trend brings the mentality of strategic confrontation back into international relations. The polarization seemingly becomes a geopolitical factor, which influences the power dynamics in Central Asia in its cultural-informational, military and economic aspects. From the cultural-informational perspective, the polarization is incompatible with the provisions of multivector foreign policies, and pursued by the Central Asian states; therefore, they attempt to neutralize the trend by withholding from taking clear-cut positions with regard to the Ukrainian events. Such a stance, however, does not provide for hedging against military threats, which are perceived as rather real in Central Asia because of the Russian modus operandi in Ukraine, as well as due to the seemingly catalyzing impact of current Russian policies on the local separatist forces and radical Islamic groups. Apprehension about a replication of a Crimean scenario as well as the asymmetric character of military threat may push the Central Asian states to

Full Text Available This article analyses the economic evolution of the former Soviet states of Central Asia since their independence, especially in regard to growth and in comparison with growing inequality. The following topics are considered: first of all, the initial conditions in whichthe economic transition of these countries began; secondly, the transformations of widely varying scope (different “routes of transition” that these economies have experienced, from an almost non-reform (Turkmenistan or a gradual or partial reform (Uzbekistan and Tajikistan, to a large-scale reform (Kyrgyzstan and Kazakhstan; and thirdly, the economic performance of the Central Asian states, which, with the exception of Uzbekistan, has been quite poor and has generated what we could call two kinds of “duality”: one which is generated by the expansion of extracting industries (oil, gas and metals, to the detriment of other sectors fundamental to the countries’ development, and another one originating from the growingunequal distribution of income among the population. While the first of these “dualities” cannot be maintained as a long-term development strategy, the second one could culminate in social agitation and instability, even in the medium term, which could contribute to thedestabilisation of the already fragile and volatile region of Central Asia.

Central Asia, Euro-centrism and Colonialism

Full Text Available The following article should not be dismissed as yet another attempt to construct a renewed round ofrevisionism in history. On the contrary, it aims to explore the possibility of scaling down the dominant Eurocentric epistemology that served as a basis for a stereotypical frame of knowledge about Central Asia. The majority of researchers of the region do not deem the need to review the scale of contradictory clashes created by the notion of Eurocentrism. The latter is reflected in numerous articles about the frozen (and sadly deadlock dilemma on why and how were the lands of Tajiks, Uzbeks and Kazakhs divided. By publishing conventional analyses on the region's "clumsy separation", experts illustrate their subaltern, narrowly framed by the colonial world, knowledge and hence, remain as gravestones of the Eurocentric methodology. In the process of such explication, the most important role is allocated to the modern culture, which encouraged the formation of the paradox, represented to us via the paraphrased Soviet aphorism: modernity and coloniality are twin brothers. The initiation of the process of decolonizing the mind within the five republics of the region is possible. One of the solutions involves recognizing the integrity of the pluralist-cycled culture and philosophy of the region. The proposed act will allow shrinking the focus on the knowledge within the limited national units and frames (thus, lessening the degree of'fetishism of the national identity', and rather creating conditions for designing the "bridge", linking different cultures, ideologies and institutional spaces in Central Asia, as a transnational intellectual matrix. The aforementioned theory will provide a basis and structure for empirical facts, and, therefore, drive the researchers from merely constituting to critically thinking, and consequently, inspire to come upon new approaches and fields of study, connecting them with the existing, colonial experiences.

Opportunities for renewable energy sources in Central Asia countries

Energy Technology Data Exchange (ETDEWEB)

Obozov, A.J. [Project KUN (Kyrgyzstan); Loscutoff, W.V. [National Renewable Energy Lab., Golden, CO (United States)

1998-07-01

This report presents an overview of the state of conventional energy sources and the potential for development of renewable energy sources in the Central Asia countries of Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan. The region has a population of about 50 million in an area of more than four million square kilometers. The per capita gross internal product is more than $2,500, although the economy has been declining the past five years. The area has substantial coal, oil, uranium, and natural gas reserves, although they are not distributed equally among the five countries. Energy production is such that the countries do not have to rely heavily on imports. One of the problems in Central Asia is that the energy prices are substantially below the world prices. This is a factor in development of renewable energy sources. The primary renewable energy resources available are wind in Kazakhstan, solar in the entire region, biomass in Kyrgyzstan, and micro-hydropower stations in Kazakhstan and Kyrgyzstan. All of these have the potential to provide a significant amount of the required energy for the region. However, all of the countries have an abundance of various renewable energy resources. To effectively use these resources, however, a number of barriers to their development and commercialization must be overcome. These include low prices of conventional energy sources, absence of legislative support, lack of financing for new technologies, and lack of awareness of renewable energy sources by the population. A number of specific actions are proposed to overcome these barriers. These include establishment of a Central Asia coordinating council for renewable energy, development of a regional renewable energy program, and setting up a number of large demonstration projects. 16 figs.

Review article: Hydrological modeling in glacierized catchments of central Asia - status and challenges

Science.gov (United States)

Chen, Yaning; Li, Weihong; Fang, Gonghuan; Li, Zhi

2017-02-01

Meltwater from glacierized catchments is one of the most important water supplies in central Asia. Therefore, the effects of climate change on glaciers and snow cover will have increasingly significant consequences for runoff. Hydrological modeling has become an indispensable research approach to water resources management in large glacierized river basins, but there is a lack of focus in the modeling of glacial discharge. This paper reviews the status of hydrological modeling in glacierized catchments of central Asia, discussing the limitations of the available models and extrapolating these to future challenges and directions. After reviewing recent efforts, we conclude that the main sources of uncertainty in assessing the regional hydrological impacts of climate change are the unreliable and incomplete data sets and the lack of understanding of the hydrological regimes of glacierized catchments of central Asia. Runoff trends indicate a complex response to changes in climate. For future variation of water resources, it is essential to quantify the responses of hydrologic processes to both climate change and shrinking glaciers in glacierized catchments, and scientific focus should be on reducing uncertainties linked to these processes.

Beyond the drug-terror nexus: drug trafficking and state-crime relations in Central Asia.

Science.gov (United States)

De Danieli, Filippo

2014-11-01

In the wake of collapse of the Soviet Union, Central Asia has transformed into a key hub along the Afghan opiates trafficking routes. Around 30 percent of the heroin manufactured in Afghanistan is estimated to be smuggled through Central Asian republics in its way to booming drug markets in Russia and Eastern Europe. Building upon available evidence and extensive fieldwork research, the article seeks to confute mainstream analyses which emphasize connections between criminal and terrorist networks. The focus is on conducive factors for the establishment of drug routes in Central Asia, the characteristics of drug related networks, and the nature of political-criminal relations across the region. It is argued that in all five Central Asia republics strategic partnerships have formed between drug traffickers and state actors around the exploitation of drug rents and that mafias' influence on politics is stronger in Tajikistan and Kyrgyzstan, the region's poorest countries. By moving the focus from narco-terror to the state-crime connections, the article provides a critical insight into political economy issues surrounding a complex and multifaceted phenomenon such as the drug trade.

Mental and ethno-psychological features of Tuvans within the system of development determinants of the Republic of Tuva: the case of ethno-tourism

Directory of Open Access Journals (Sweden)

Svetlana A. Madyukova

2018-06-01

Full Text Available Ethno-tourism is now often seen as an economic and sociocultural determinant of regional development in the Republic of Tuva. This is now understood by the regional authorities, embodied in a certain amount of legislation and implemented through a number of action plans. However, the work of the authorities relies largely on economic resources available. In this article, the author chose to focus on Tuvan mental and ethno-psychological features which can either facilitate or impede the progress of tourism in the region. Among these significant features of Tuvan ethnic character are the small degree of mental openness to outside influence, the high importance of family affinities and of belonging to kinship groups, the collectivist way of thinking, national pride and love of the homeland, low acquisitive demands (especially concerning money, a certain inertia of behavior, the presence of specific ‘Tuvan time’, bilingualism and the negative image of Tuvans in mass media – an image which does not match the self-image of Tuvans. Having analyzed festivals and ethnic celebrations in Tuva which can be classified as resources of event tourism, the author focused on one of the most implication-rich aspects of developing ethno-tourism in the region. It concerns the value-based and ethical transformation of the ethnic self-consciousness which found their expression in desacralization and commercialization of traditional culture. Ethno-tourism appears to be the most “eloquent” practice in the rise of this ersatz culture, where traditional cuisine is simplified, cheaper cloth and machine embroidery is used, the traditional designs, such as that of the yurta, appear in commercial projects, e.g. of holiday camps. The author concludes that, on the one hand, increasing popularity of ethno-tourism in Tuva can propel the industry to becoming an important economic determinant of regional development. More positive influences can be expected in potential

Hydrocarbon-Rich Territories in Central Asia: Producing Countries, Exporting Enclaves or Transit Countries?

Full Text Available This article aims to qualify the different analyses and currents of opinion that are circulating with respect to Central Asia’s capacity to become one of the main exporters of hydrocarbons in the next decade. For this, it first examines whether or not, in quantitativeterms, the hydrocarbon-rich territories of Central Asia can become one of the main suppliers on a world scale; secondly, it explains why the countries of Central Asia will play a necessarily different role on the international energy scene than that played by the OPEC countries; and, finally, it indicates what the relevance of this area could be in the organisation (structure of the contemporary international energy scene. In this sense, it discusses not producing countries, but rather countries of passage.

The quest for the oil and gas infrastructure protection in central Asia : time bombs and policy options

Energy Technology Data Exchange (ETDEWEB)

Bi, J. [Carleton Univ., Ottawa, ON (Canada). Norman Paterson School of International Affairs

2006-03-15

The growing economies of China and India have increased global anxieties over dwindling fossil fuel resources. Regional countries in central Asia have advocated for more extensive strategic partnerships within the oil and gas industry as insurance against the pressures of more powerful nations. However, non-traditional threats such as terrorism raise serious questions about critical oil and gas infrastructure protection in central Asia. This paper assessed the vulnerability and threats inherent in protecting the critical oil and gas infrastructure of Central Asia, with a specific focus on Kazakhstan, Turkmenistan, Uzbekistan, and the region of Xinjiang in China. An-depth analysis of the development strategies, terrorist threats, and water issues confronted by Central Asian powers was conducted to demonstrate their vulnerability. The analysis was then used to consider options available for managing oil and gas infrastructure in the regions. It was observed that different perceptions and technological difficulties have made cooperation on critical oil and gas infrastructure protection less important than national sovereignty and domestic stability. It was concluded that a low-key approach to homeland security and oil and gas infrastructure may be the best strategy for Central Asia and China. 44 refs.

Diversity of the Mountain Flora of Central Asia with Emphasis on Alkaloid-Producing Plants

Directory of Open Access Journals (Sweden)

Karimjan Tayjanov

2017-02-01

Full Text Available The mountains of Central Asia with 70 large and small mountain ranges represent species-rich plant biodiversity hotspots. Major mountains include Saur, Tarbagatai, Dzungarian Alatau, Tien Shan, Pamir-Alai and Kopet Dag. Because a range of altitudinal belts exists, the region is characterized by high biological diversity at ecosystem, species and population levels. In addition, the contact between Asian and Mediterranean flora in Central Asia has created unique plant communities. More than 8100 plant species have been recorded for the territory of Central Asia; about 5000–6000 of them grow in the mountains. The aim of this review is to summarize all the available data from 1930 to date on alkaloid-containing plants of the Central Asian mountains. In Saur 301 of a total of 661 species, in Tarbagatai 487 out of 1195, in Dzungarian Alatau 699 out of 1080, in Tien Shan 1177 out of 3251, in Pamir-Alai 1165 out of 3422 and in Kopet Dag 438 out of 1942 species produce alkaloids. The review also tabulates the individual alkaloids which were detected in the plants from the Central Asian mountains. Quite a large number of the mountain plants produce neurotoxic and cytotoxic alkaloids, indicating that a strong chemical defense is needed under the adverse environmental conditions of these mountains with presumably high pressure from herbivores.

Constrained Magnetostratigraphic Dating of a Continental Middle Miocene Section in the Arid Central Asia

Directory of Open Access Journals (Sweden)

Verena Verestek

2018-05-01

Full Text Available The Neogene succession of the Aktau Mountains in the Ili Basin, southeast Kazakhstan, is a terrestrial archive well suited for researching the role of Central Asia in Miocene climate evolution. We present an integrated approach for dating the well-exposed Bastau Formation, based on magnetostratigraphy and constraints from cyclostratigraphy and biostratigraphy. Stepwise demagnetization yielded characteristic remanence directions that are consistent with those expected for the Miocene in Central Asia. The reddish-colored alluvial floodplain deposits and gray lacustrine deposits show partly complex magnetic behavior with magnetite and hematite as the main magnetic carriers, with variable demagnetization behavior and non-dipolar normal and reverse polarity directions. The observed magnetic properties are best explained by depositional variability and magneto-mineralogical alteration effects of both dissolution and neo-formation of magnetite, including significant secondary magnetization. The mean of reverse polarity directions is flatter than the expected Middle Miocene Earth magnetic field, which is an indicator for the existence of inclination shallowing that supports a primary origin. Detailed rock magnetic analyses are used to analyze the nature of the characteristic remanent magnetization and to discriminate primary and secondary remanence directions in order to obtain a reliable magnetostratigraphic result. The proposed age of 15.3–13.9 Ma for the Bastau Formation corresponds to the known biostratigraphic setting, matches with typical sedimentation rates of foreland basins in Central Asia, and coincides with spectral analysis of geochemical proxies of that section. The resulting age model serves as a robust framework for paleoclimate reconstruction of Neogene climate dynamics in Central Asia.

Full Text Available The author analyses the European Union’s foreign policy in Central Asia. He indicates the basic tendencies of development of the EU cooperation with the countries of Central Asian region. Further, the author analyzes the implementation of joint projects within the framework adopted by the Partnership Agreements. Based on a critical analysis, the researcher highlights a number of constraints to effective development of relations between the EU and Central Asian states. He carries out a structural analysis of conceptual documents of the European Union for the development of bilateral and multilateral relations with Central Asian countries in the region. Scientific novelty of this work lies in the systematization of stages in the evolution of relations between the European Union and the countries of Central Asia. The author divides the formation of cooperation into four main stages. The first stage of the relations between the EU and the countries of Central Asia includes conceptual framework of the legal regulatory structure of bilateral and multilateral cooperation. The second stage is characterized by the realization of a number of joint projects in the field of transport communications, democratic transformations, regional security and stability. The third stage of the relations is determined by acquiring of special geographical significance of the region of Central Asia resulting from the engagement of the International Security Assistance Force in Afghanistan in 2001. The fourth stage has begun in 2015 with the adoption of the EU Strategy for a New Partnership with Central Asia for 2017-2021. These studies serve as a basis for developing some important proposals and recommendations for the improvement of the effectiveness of cooperation between the parties.

Abrupt climatic events recorded by the Ili loess during the last glaciation in Central Asia: Evidence from grain-size and minerals

The loess record of Central Asia provides an important archive of regional climate and environmental changes. In contrast to the widely investigated loess deposits in the Chinese Loess Plateau, Central Asian loess-paleosol sequences remain poorly understood. Here, we present an aeolian loess section in the southern Ili Basin. Based on granularity and mineralogical analyses, we reconstruct climatic changes during the last glaciation. The results indicated that most of the abrupt climatic events (such as Dansgaard-Oeschger events and Heinrich events) were imprinted in this loess section, although their amplitudes and ages showed some differences. Compared with the millennial oscillations recoded in loess and stalagmites in East Asia, the arid Central Asia responded more sensitively to the warming events than to the cooling events. The shifting trajectory of westerlies across Central Asia played an important role in dust deposition during the stadials. The North Atlantic climatic signals may have been transmitted from Central Asia to the East Asian monsoon regions via the westerlies.

The dynamics of aridity in Central Asia for over the past 12,000 years has been analyzed using deep ice core records recovered from the Siberian Altai, Tien Shan and Pamir glaciers. An analysis of aridity in the 20-21 centuries based on the long-term meteorological observations complements the paleo- climate reconstruction. The goal of our research is to examine an aridity (at low and high temperatures) in Central Asia as a complex of characteristics including air temperature-precipitation relationship (Koppen, 1918, Geiger, 1961, Mezencev, 1973), intensity of dust loading and biomass burning. The stable isotope ratio, soluble ionic and insoluble particulate geochemical components and oxalate preserved in ice were considered in relation to climatic and environmental changes; and to determine the main aerosol sources using ground- and upper-level meteorological data. Multivariate statistical methods were employed for examination of the main geo-chemical components responsible for the preserved aridity variability. Insoluble particle concentrations preserved in the ice core were affected mainly by precipitation regimes and wind speed. Concentration of all size particles was found to be negatively correlated with monthly temperatures indicating low temperatures during the dry particle deposition. Two abrupt depletions in stable isotope records, i.e., Younger Dryas and Centurial Sever Drought (CSD), occurred during cold, dry, windy periods of intensified dust storms in large desert areas. When climate became colder and drier, the Central Asian deserts extended, wind speeds increased loading mineral dust to atmosphere, which formed inversion while the convection processes and precipitation occurrence were limited. Warmer and wetter conditions are associated with less dust loading that occurred during the Holocene climate optimum, medieval warm and modern warm periods. The sudden climate transitions are accompanied by the most intensifying mineral dust loading. From the

Building a Higher Education Area in Central Asia: challenges and prospects

2014-12-01

Full Text Available In recent years, for a variety of reasons, higher education has begun to be considered much more frequently than previously in terms of ‘regions’, or ‘macro-regions’. Although for decades countries sharing some characteristics, or perceived as geographically or culturally closely related to each other, have promoted forms of cooperation between their higher education institutions (with varying degrees of success, it is now widely accepted that to ‘count’ on the world stage, it is useful for single countries, and especially for smaller countries, to work together with a view to making their systems better able to interact and hopefully to promote, increase and make visible their merits. Of course, in higher education as in many other fields, the regions or macro-regions are not defined once and for all, but are the result of stronger or weaker ad hoc groupings which take into account different factors in different contexts. Central Asia is one such potential region: it does not have unquestioned boundaries, but like other macro-regions, and more so than most, it can be understood and constructed in different ways. A current shared understanding of ‘Central Asia’ is that it is formed by the 4 ex-Soviet Republics of Central Asia (Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, plus Kazakhstan. Over the last decade the possibility of building a Higher Education Area in those five republics has been explored, and a large-scale project which uses Tuning methodology to this end is under way. This project, called TuCAHEA (“Towards a Central Asian Higher Education Area: Tuning Structures and Building Quality Culture”, has already elaborated a Central Asian list of Generic Competences and eight Subject Area Groups have formulated their Reference Points and Guidelines. The five Ministries of the five countries have signed a Communiqué indicating their intention to collaborate more closely; a pilot student mobility scheme is soon

2010-05-01

Investigation of atmospheric transport of arid aerosol from Central Asia was held within the ISTC project 3715. Particular attention was paid to the removal of aerosol from the Aral Sea region and its further transport, because aerosol and pollutants emission from Central Asia affect the airspace of the entire Asian continent. At the same time measurements of aerosols in the atmosphere of Central Asia are holding in a small number of stations, and currently available data are insufficient to define the initial conditions and/or verification of models of long-range transport. To identify sources of pollution transported from Central Asia, in Kyrgyzstan measurement and sampling of air were organized: at the station on the northern slope of the Kirgiz Range, 30 km south of Bishkek, at an altitude of 1700 m above sea level (Bishkek Site, 42,683N; 74,694E ), and on permanent alpine Teploklyuchenka lidar station in the Central Tien Shan at an altitude of 2000 m above sea level (Lidar Site, 42,467N; 78,533E). The chemical analysis of collected aerosol and soils samples was carried out. Measurements of aerosol at these stations have been merged with the simulation of the trajectories of air masses in the study region and with the satellite (the Terra and Aqua satellites) observations of aerosol optical thickness in this region. Satellite data for the region 43-47 N, and 58-62 E (Aral Sea) from April 2008 to September 2009 were analyzed. The moments were selected, when the value of aerosol optical thickness (AOT) was greatest (more than 0.5), and the transport from the Aral Sea region to the observation sites took place. For each of these days, the forward trajectories, which started at 6 points within the region, were calculated using the HYSPLIT model. The days, on which the trajectories reached the BISHKEK and LIDAR sites, were determined from the data obtained. Calculations on the basis of the RAMS model were performed for these days. These calculations were performed

In March of 2000, scientists from four nuclear physics research institutes in the Central Asia Republics of Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan, and the U.S. Sandia National Laboratories embarked on a three-year cooperative transboundary river monitoring experiment. The experiment, named Navruz (meaning 'new beginning'), uses standardized methods to monitor basic water quality parameters, radionuclides, and metals in the Syr Darya and Amu Darya rivers. Overall, the project addresses three main goals: (1) to help increase capabilities in Central Asian nations for sustainable water resources management; (2) to provide a scientific basis for supporting nuclear transparency and non-proliferation in the region; and (3) to help reduce the threat of conflict in Central Asia over water resources. Contamination of these rivers is a result of growing population, urbanization, agricultural uses, and radioactive and metals contamination from a legacy of uranium mining, industry, and other activities of the former Soviet Union. The project focuses on waterborne radionuclides and metals because of the importance of these contaminants to public health and political stability in Central Asia. Moreover, the method of enabling scientists from bordering countries to study a transboundary problem, can lead to a greater scientific understanding, consensus on necessary mitigation steps, and ultimately the political resolution of the issue. The project scope, approach, and preliminary results are presented. (author)

Rozwadowski Andrzej

2017-06-01

Full Text Available The paper describes the story of discovering South African rock art as an inspiration for research in completely different part of the globe, namely in Central Asia and Siberia. It refers to those aspect of African research which proved to importantly develop the understanding of rock art in Asia. Several aspects are addressed. First, it points to importance of rethinking of relationship between art, myth and ethnography, which in South Africa additionally resulted in reconsidering the ontology of rock images and the very idea of reading of rock art. From the latter viewpoint particularly inspiring appeared the idea of three-dimensionality of rock art ‘text’. The second issue of South African ‘origin,’ which notably inspired research all over the world, concerns a new theorizing of shamanism. The paper then discusses how and to what extent this new theory add to the research on the rock art in Siberia and Central Asia.

Central Asian dry lands are grass- and desert shrub-dominated ecosystems stretching across Northern Eurasia. This region supports a population of more than 100 million which continues to grow at an average rate of 1.5% annually. Dry steppes are the primary grain and cattle growing zone within Central Asia. Degradation of this ecosystem through burning and overgrazing directly impacts economic growth and food supply in the region. Fire is a recurrent disturbance agent in dry lands contributing to soil erosion and air pollution. Here we provide an overview of inter-annual and seasonal fire dynamics in Central Asia obtained from remotely sensed data. We evaluate the accuracy of the Moderate Resolution Imaging Spectroradiometer (MODIS) global fire products within Central Asian dry lands and use these products to characterize fire occurrence between 2001 and 2009. The results show that on average ˜15 million ha of land burns annually across Central Asia with the majority of the area burned in August and September in grasslands. Fire is used as a common crop residue management practice across the region. Nearly 89% of all burning occurs in Kazakhstan, where 5% and 3% of croplands and grasslands, respectively, are burned annually.

Argas vespertilionis is a geographically widespread haematophagous ectoparasite species of bats in the Old World, with a suspected role in the transmission of Babesia vesperuginis. The aims of the present study were (1) to molecularly screen A. vespertilionis larvae (collected in Europe, Africa and Asia) for the presence of piroplasms, and (2) to analyze mitochondrial markers of A. vespertilionis larvae from Central Asia (Xinjiang Province, Northwestern China) in a phylogeographical context. Out of the 193 DNA extracts from 321 A. vespertilionis larvae, 12 contained piroplasm DNA (10 from Hungary, two from China). Sequencing showed the exclusive presence of B. vesperuginis, with 100% sequence identity between samples from Hungary and China. In addition, A. vespertilionis cytochrome oxidase c subunit 1 (cox1) and 16S rRNA gene sequences had 99.1-99.2 and 99.5-100% similarities, respectively, between Hungary and China. Accordingly, in the phylogenetic analyses A. vespertilionis from China clustered with haplotypes from Europe, and (with high support) outside the group formed by haplotypes from Southeast Asia. This is the first molecular evidence on the occurrence of B. vesperuginis in Asia. Bat ticks from hosts in Vespertilionidae contained only the DNA of B. vesperuginis (in contrast with what was reported on bat ticks from Rhinolophidae and Miniopteridae). Molecular taxonomic analyses of A. vespertilionis and B. vesperuginis suggest a genetic link of bat parasites between Central Europe and Central Asia, which is epidemiologically relevant in the context of any pathogens associated with bats.

In Central Asia, the water deficit and water-energy problem have been one of among the most acute and conflict-ridden challenges for the sustainable development of the region and for regional security. Key trade and investment partners, including Russia and the European Union, could play a considerable role in influencing this issue, due to the long-lasting status quo, the inability to find a solution through intra-regional dialogue and the region’s rising dependence on foreign trade. Indeed,...

2017-06-01

Full Text Available This essay also gives an idea of recent research trends and topics in music education in Central Asia. It consists of five parts including teaching music history, teaching epics, teaching songs and instrumental music, teaching traditional instruments, and dictionaries and language resources. Because of the extraordinary increase in the number of books published recently, a careful selection has been made in order to keep the references section to an acceptable length. Hence, the bibliography does not embody all of the works of a single author on the topic. This essay covers books and textbooks dealing with the music of Kazakhstan and the Kyrgyz Republic—two neighboring countries with strong common historical roots and closely related musical traditions. In addition to reviewing textbooks published in Kazakhstan and the Kyrgyz Republic, this article includes some relevant works by Russian authors. However, the extensive body of works authored by Central Asian scholars abroad was excluded from this essay. It contains references only in Kazakh, Kyrgyz, and Russian languages.

Russia's projects and investments in Central Asia: the oil and gas industry

OpenAIRE

Paramonov, Vladimir; Strokov, Aleksei

2008-01-01

In the 1990s, Russia's projects and investments in the Central Asian oil and gas industry were mainly concentrated in Kazakhstan, while its interest in other states of the region were minimal. When Vladimir Putin became Russian president in 2000 and the price of hydrocarbons steadily rose, Central Asia's importance abruptly increased. This caused the Russian Federation and Russian oil and gas companies to drastically step up their activity not only in Kazakhstan, but also in Turkmenistan and ...

In the frames of ISTC project #3715 for an overview of the year evolution of aerosol in Central Asia the analysis of aerosol optical thickness (AOT) was producing. Monitoring of AOT was making on the base of AOT satellite observation by MODIS devices, located on board of the Terra and Aqua satellites. The region was 34-51 N, and 54-96 E for the year 2007. The analysis revealed that AOT in the region is characterized by pronounced annual pace with the rapid growth of AOT winter, spring peak (τ ~ 0,4), the slow decline of ALO spring to autumn and autumn minimum (τ ~ 0,2). In August a weak secondary maximum of AOT took place. In mid-June and in the first decade of July and August in the region had increased the value of AOT, accompanied by significant increase in AOT volatility. In particular, 8 and 9 August, the average for the region AOT exceeded 0.6. Diagnosis of aerosol emissions was based on an analysis of the spatial and temporal changes of AOT field. Obviously, the spatial scale of data and data discretization in time determines the emissions of power can be diagnosed. The spatial AOT distribution shows that aerosol plumes from the area of the Aral Sea in 2007 were carried out mainly by southeastern and eastern fronts. In the region, there are two major sources of aerosol emissions: one of them located in the south of the Aral Sea and the Kara-Kum desert, and a second, more powerful - over Taklamakan desert. Particularly, data were obtained on the dust storms occurrence of December 15, 2007 in the southern Aral Sea region. In order to detect its influence on the Kyrgyzstan stations dust measurements, simulations of the dust plume from the area of Aral Sea were produced by SILAM model of Finnish Meteorological Institute. Two sets of runs have been performed: forward simulations for estimation of the area affected by the dust elevated by the wind during the storm from the area of Aral Sea. The model has evaluated 5-day dispersion of the plume. The second run

Quantitative Biostratigraphic Analysis of Central Asia with Implications for the Tien Shan of Kyrgyzstan

McLaughlin, W. N.; Hopkins, S. S.

2013-12-01

Central Asia lies at a nexus both in terms of geology and evolutionary biogeography. With the convergence of the Indian and Asian plates creating high rates of deformation over broad regions, shortening of the Paleozoic and Mesozoic basement rocks has created a rich history of late Cenozoic sedimentary basins. In fact, Kyrgyzstan is the most seismically active country in the world. Additionally, Central Asia is a biogeographic crossroads, facilitating the intercontinental migrations of distant faunas from North American, Europe, Africa, and Southern Asia. With such an active geologic and biological evolution, the usefulness of temporal constraints is apparent. However, the continental collision environment has provided few volcanic rocks suitable for radiometric dating. Therefore, while less precise, the biostratigraphic analysis of Central Asia I present is an ideal method for both establishing ages and correlating between disparate basins. The last several decades provided great advancements in quantitative biostratigraphic methods applied to marine microfossils from drill cores. While these newer methods such as RASC (ranking and scaling), its sister program CASC, and CONOP (constrained optimization) provide a clear improvement over older methods such as graphic correlation, they have yet to be applied to terrestrial vertebrate faunas. Graphic correlation only allows comparison between two stratigraphic columns at a time and is heavily weighted by the initial selection of a type section. Both RASC and CONOP compare all stratigraphic sections simultaneously, eliminating type section bias. Previous vertebrate biostratigraphy methods attempted to predict FADs and LADs with the assumption they are generally minimum estimates. RASC instead establishes average stratigraphic ranges for each taxon and with CASC actually provides confidence intervals for each prediction, reducing the potential error resulting from reworking. CONOP generates maximum stratigraphic ranges

Impact of Desiccation of Aral Sea on the Regional Climate of Central Asia Using WRF Model

Science.gov (United States)

Sharma, Ashish; Huang, Huei-Ping; Zavialov, Peter; Khan, Valentina

2018-01-01

This study explores the impacts of the desiccation of the Aral Sea and large-scale climate change on the regional climate of Central Asia in the post-1960 era. A series of climate downscaling experiments for the 1960's and 2000's decades were performed using the Weather Research and Forecast model at 12-km horizontal resolution. To quantify the impacts of the changing surface boundary condition, a set of simulations with an identical lateral boundary condition but different extents of the Aral Sea were performed. It was found that the desiccation of the Aral Sea leads to more snow (and less rain) as desiccated winter surface is relatively much colder than water surface. In summer, desiccation led to substantial warming over the Aral Sea. These impacts were largely confined to within the area covered by the former Aral Sea and its immediate vicinity, although desiccation of the Sea also led to minor cooling over the greater Central Asia in winter. A contrasting set of simulations with an identical surface boundary condition but different lateral boundary conditions produced more identifiable changes in regional climate over the greater Central Asia which was characterized by a warming trend in both winter and summer. Simulations also showed that while the desiccation of the Aral Sea has significant impacts on the local climate over the Sea, the climate over the greater Central Asia on inter-decadal time scale was more strongly influenced by the continental or global-scale climate change on that time scale.

Radioactive Waste Management in Central Asia - 12034

Energy Technology Data Exchange (ETDEWEB)

Zhunussova, Tamara; Sneve, Malgorzata; Liland, Astrid [Norwegian Radiation Protection Authority (Norway)

2012-07-01

After the collapse of the Soviet Union the newly independent states in Central Asia (CA) whose regulatory bodies were set up recently are facing problems with the proper management of radioactive waste and so called 'nuclear legacy' inherited from the past activities. During the former Soviet Union (SU) period, various aspects of nuclear energy use took place in CA republics of Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan. Activities range from peaceful use of energy to nuclear testing for example at the former Semipalatinsk Nuclear Test Site (SNTS) in Kazakhstan, and uranium mining and milling industries in all four countries. Large amounts of radioactive waste (RW) have been accumulated in Central Asia and are waiting for its safe disposal. In 2008 the Norwegian Radiation Protection Authority (NRPA), with the support of the Norwegian Ministry of Foreign Affairs, has developed bilateral projects that aim to assist the regulatory bodies in Kazakhstan, Kyrgyzstan Tajikistan, and Uzbekistan (from 2010) to identify and draft relevant regulatory requirements to ensure the protection of the personnel, population and environment during the planning and execution of remedial actions for past practices and radioactive waste management in the CA countries. The participating regulatory authorities included: Kazakhstan Atomic Energy Agency, Kyrgyzstan State Agency on Environmental Protection and Forestry, Nuclear Safety Agency of Tajikistan, and State Inspectorate on Safety in Industry and Mining of Uzbekistan. The scope of the projects is to ensure that activities related to radioactive waste management in both planned and existing exposure situations in CA will be carried out in accordance with the international guidance and recommendations, taking into account the relevant regulatory practice from other countries in this area. In order to understand the problems in the field of radioactive waste management we have analysed the existing regulations through

The Navruz Project engages scientists from nuclear physics research institutes and water science institutions in the Central Asia Republics of Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan, and Sandia National Laboratories. The project uses standardized methods to monitor basic water quality parameters, radionuclides, and metals in the Syr Darya and Amu Darya rivers. Phase I of the project was initiated in 2000 with 15 sampling points in each of the four countries with sample analysis performed for over 100 parameters. Phase II of the project began in 2003 and expanded sampling to include at least 30 points in each country in an effort to characterize ''hot spots'' and to identify sources. Phase III of the project began in 2006 and will integrate decision support modeling with the existing monitoring. Overall, the project addresses four main goals: to create collaboration among Central Asian scientists and countries; to help increase capabilities in Central Asian nations for sustainable water resources management; to provide a scientific basis for supporting nuclear transparency and nonproliferation in the region; and to help reduce the threat of conflict in Central Asia over water resources. Contamination of these rivers is a result of growing population, urbanization, and agricultural activities, as well as radioactive contamination from a legacy of uranium mining and related activities of the former Soviet Union. The project focuses on waterborne radionuclides and metals because of the importance of these contaminants to public health and political stability in Central Asia.

Full Text Available The article examines the earliest stages of the history of the Tatars. The origins of the Tatars are traced from the collapse of both the Han Empire and the Empire of Xiongnu and are considered during the subsequent periods preceding the emergence of the empire of Genghis Khan. The author argues that the Tatar state appeared long before the Mongol era, providing information on the resettlement of the Tatars in the 9th and 10th centuries, which explains why a century later the Mongols, who occupied the same space, were called the “Tatars” in the Turkic and Muslim environment, as well as in China. This Turkic desig­nation of the Mongols took root not only in Central Asia and the Middle East but also in Russia and Western Europe.

The study of lake level changes in arid region of Central Asia not only has important significance for the management and sustainable development of inland water resources, but also provides the basis for further study on the response of lakes to climate change and human activities. Therefore, in this paper, eleven typical lakes in Central Asia were observed. The lake edges were obtained through image interpretation using the quasi-synchronous MODIS image, and then water level information with long period (2002-2015) was acquired using ENVISAT/RA-2 and Cryosat-2 satellite borne radar altimeter data. The results show that these 11 lakes all have obvious seasonal changes of water level in a year with a high peak at different month. During 2002 - 2015, their water levels present decreased trend generally except Sarygamysh Lake, Alakol Lake and North Aral Sea. The alpine lakes are most stables, while open lakes’ levels change the most violently and closed lakes change diversely among different lakes.

The Water Efficiency Paradox, a study of Central Asia

Science.gov (United States)

Merks, Joreen; Bastiaanssen, Wim

2017-04-01

Water scarcity is a rapidly growing concern in the semi-arid areas of Central Asia. Water savings and efficiency improvement programs are promoted as a possibility to save the Aral Sea. The Aral Seas lost 92% of its volume between 1960 and 2009. Projects on rehabilitating the Aral Sea and increasing the efficiency of water use in the irrigation sector are, however, not making progress. In Central Asia, 90% of the water withdrawal is allocated to agriculture. Irrigation efficiency programs often disregard the downstream connectivity of the water flow path. Not all water being applied is consumed by crop evapotranspiration and in fact an equally great portion of water returns back into the river basin system and is reused downstream. This cascade effect implies that results in one location can induce a scarcity of water in another location. The cascade effect in the Syr Darya has been studied by means of the Aral Sea Basin Management Model (ASBMM) designed by SIC-ICWC and remote sensing data produced by UNESCO-IHE. We will demonstrate the impact of increasing irrigation efficiency locally on the overall water consumption in the basin. We will show that efficiency increases with larger areas, and that there are caps to the maximum efficiency at basin scale. Increasing efficiency is thus not self-evident. Classical solutions on promoting increase of efficiency and water savings are therefore outdated and misleads stakeholders. We will look into the misconceptions and challenges in the communication between researchers and policy makers regarding increasing efficiency.

Energy investment and trade opportunities emerging in Central Asia, Northwest China

Cooperation in the business of oil and natural gas among governments of Central Asia and Northwest China could help the countries overcome obstacles to development of their vast petroleum resources. The most important obstacle facing these countries is also the one most widely discussed: limited infrastructure for transporting energy. But there are other problems holding back oil and gas development. They include poor communications infrastructure, unstable government structures, political conflict, payments difficulties, and inadequate energy policies. For countries analyzed in a recent Asian Development Bank (ADB) study of economic cooperation in the region--Uzbekistan, Kazakhstan, the Kyrgyz Republic, and the Xinjiang autonomous region of the People's Republic of China (Xinjiang PRC)--oil and gas are the most abundant and valuable natural resources. While Central Asia is poised to become a major world supplier of energy, especially oil and gas, countries in the region emphasize energy self-sufficiency at the expense of developing new trading linkages. Governments thus tend to ignore the benefits of regional cooperation and remain reluctant to commit to area-wide trade and other forms of cooperation. The paper discusses oil and gas sectors; major energy trends, including restructuring, foreign investment, and energy diversification; opportunities for cooperation; impediments to cooperation; and models of cooperation

Lakes in arid regions of Central Asia act as essential components of regional water cycles, providing sparse but valuable water resource for the fragile ecological environments and human lives. Lakes in Central Asia are sensitive to climate change and human activities, and great changes have been found since 1960s. Mapping and monitoring these inland lakes would improve our understanding of mechanism of lake dynamics and climatic impacts. ICESat/GLAS satellite laser altimetry provides an efficient tool of continuously measuring lake levels in these poorly surveyed remote areas. An automated mapping scheme of lake level changes is developed based on GLAS altimetry products, and the spatial and temporal characteristics of 9 typical lakes in Central Asia are analyzed to validate the level accuracies. The results show that ICESat/GLAS has a good performance of lake level monitoring, whose patterns of level changes are the same as those of field observation, and the max differences between GLAS and field data is 3cm. Based on the results, it is obvious that alpine lakes are increasing greatly in lake levels during 2003-2009 due to climate change, while open lakes with dams and plain endorheic lakes decrease dramatically in water levels due to human activities, which reveals the overexploitation of water resource in Central Asia.

Biothreat Reduction and Economic Development: The Case of Animal Husbandry in Central Asia.

Science.gov (United States)

Walker, Robert; Blackburn, Jason

2015-01-01

Improving human welfare is a critical global concern, but not always easy to achieve. Complications in this regard have been faced by the states of the Former Soviet Union, where socialist-style economic institutions have disappeared, and the transition to a market economy has been slow in coming. Lack of capital, ethnic conflict, and political instability have at times undermined the institutional reform that would be necessary to enable economic efficiency and development. Nowhere are such challenges more pronounced than in the new nation states of central Asia, including Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Here, a severe climate limits agriculture, and industrialization has been inhibited by lack of infrastructure, low levels of human capital, and a scarcity of financial resources. These conditions are aggravated by the fact that the central Asian states are landlocked, far from centers of market demand and capital availability. Despite these daunting barriers, development potential does exist, and the goal of the paper is to consider central Asia's pastoral economy, with a focus on Kazakhstan, which stands poised to become a regional growth pole. The article pursues its goal as follows. It first addresses the biothreat situation to central Asian livestock herds, the most significant existing impediment to realizing the full market potential of the region's animal products. Next, it provides an outline of interventions that can reduce risk levels for key biothreats impacting central Asia, namely foot and mouth disease (FMD), which greatly impacts livestock and prohibits export, and Brucellosis, a bacterial zoonosis with high incidence in both humans and livestock in the region. Included is an important success story involving the FMD eradication programs in Brazil, which enabled an export boom in beef. After this comes a description of the epidemiological situation in Kazakhstan; here, the article considers the role of wildlife in

Rare earth elements (REE), with their unique physical and chemical properties, are an essential part of modern living. REE have enabled development and manufacture of high-performance materials, processes, and electronic technologies commonly used today in computing and communications, clean energy and transportation, medical treatment and health care, glass and ceramics, aerospace and defense, and metallurgy and chemical refining. Central Asia is an emerging REE and rare metals (RM) producing region. A newly compiled inventory of REE-RM-bearing mineral occurrences and delineation of areas-of-interest indicate this region may have considerable undiscovered resources.

The Russian-Soviet legacies in reshaping the national territories in Central Asia: A catastrophic case of Tajikistan

Full Text Available In every period of history many parts and territories of the world divide and get a new shape. There are lots of such examples. One clear example is the so-called ‘Grate Game’ and division of Central Asia by the British and Russian Empires. In general, Central Asian region has been under Russian influence for more than 150 years. Today in the 21st century Central Asia once again is facing a new ‘Great Game’, but this time with new and non-traditional powers in the region like the U.S. and China, which challenge the influence of region's traditional power – Russia. This paper tries to touch upon the situation and the tragic fate of Tajiks during the Russian-Soviet empires within the different political entities, administrations and territories. It analyzes the impact of Russian and Soviet legacies and territorial policies on Tajiks and Tajikistan. According to the findings of this paper, most of the previous Western and other foreign authors occasionally and briefly opine about this topic, especially about the catastrophic impact of the Russian and Soviet territorial legacies to the Tajik nation, in their work mainly focusing on the history of Central Asia. The paper draws together the main conclusions of relevant literature and tries to fill the gap within the body of existing literature and understandings concerning the topic.

Central Asia is experiencing one of the fastest growing HIV epidemics in the world, with some areas' infection rates doubling yearly since 2000. This study examines the impact of multilevel stigma (individual, family, and community) on uptake of HIV testing and receipt of HIV testing results among women in Central Asia. The sample consists of 38,884 ever-married, Central Asian women between the ages of 15 and 49. Using multilevel modeling (MLM), HIV stigma variables at the individual, family, and community levels were used to assess the significance of differences in HIV testing and receipt of HIV test results among participants while adjusting for possible confounding factors, such as age, wealth, and education. MLM results indicate that HIV stigma is significantly associated with decreased HIV testing uptake at the individual, family, and community levels and with a decrease in receipt at the community level. A one standard deviation increase in individual, family, and community level composite stigma score was associated with a respective 49 %, 59 %, and 94 % (p hinder HIV testing uptake and at the community level to hinder receipt. These findings have important interventions implications to improve uptake of HIV testing and receipt of HIV test results.

The European Centre for Disease Prevention and Control (ECDC) supports countries to monitor progress in their response to the HIV epidemic. In line with these monitoring responsibilities, we assess how, and to what extent, the continuum of care is being measured across countries. The ECDC sent out questionnaires to 55 countries in Europe and Central Asia in 2014. Nominated country representatives were questioned on how they defined and measured six elements of the continuum. We present our results using three previously described frameworks [breakpoints; Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets; diagnosis and treatment quadrant]. Forty countries provided data for at least one element of the continuum. Countries reported most frequently on the number of people diagnosed with HIV infection (37; 93%), and on the number in receipt of antiretroviral therapy (ART) (35; 88%). There was little consensus across countries in their approach to defining linkage to, and retention in, care. The most common breakpoint (>19% reduction between two adjacent elements) related to the estimated number of people living with HIV who were diagnosed (18 of 23; 78%). We present continuum data from multiple countries that provide both a snapshot of care provision and a baseline against which changes over time in care provision across Europe and Central Asia may be measured. To better inform HIV testing and treatment programmes, standard data collection approaches and definitions across the HIV continuum of care are needed. If countries wish to ensure an unbroken HIV continuum of care, people living with HIV need to be diagnosed promptly, and ART needs to be offered to all those diagnosed. © 2017 The Authors.

EU-Russia Relations Regarding Water Resources in Central Asia

2014-05-01

Full Text Available In Central Asia, the water deficit and water-energy problem have been one of among the most acute and conflict-ridden challenges for the sustainable development of the region and for regional security. Key trade and investment partners, including Russia and the European Union, could play a considerable role in influencing this issue, due to the long-lasting status quo, the inability to find a solution through intra-regional dialogue and the region’s rising dependence on foreign trade. Indeed, water-related interactions between Russia and the EU have been developing in a complementary manner. The EU possesses new technologies and its members have access to long-term capital markets, while Russia carries influence through providing security, regulating migration and holding a favourable political position for offering mediation services to the republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. This article examines EU-Russia relations regarding water issues in Central Asia over the medium term. By analyzing cooperative and non-cooperative strategies used by the major stakeholders in the water conflict (the five republics and the third parties of Russia and the EU, it confirms the continuous complementary character of EU and Russian activities in this context. Russia will take responsibility for moderating the principal questions (as with the construction of big dams such as Rogunor Kambarata, as they relate to the provision of security guarantees. The EU will act through providing support for water companies from small and medium-sized enterprises, and promoting the European Water Initiative principles and by developing its investment policy. The intersection of interests is possible when if Russia will attracts an independent arbiter, such as an actor available to provide guarantees related to the values of professional objectivism, human rights support and environment protection. These issues inevitably arise with

Rheumatologic and public health services of Central Asia's republics have suffered hugely as a result of social and economic declines following the dissolution of the Union of Soviet Socialist Republics (USSR) and transition of these republics to market economies. Between 1990 and 2000 there was a mass outflow of highly skilled rheumatologists and teachers and researchers in rheumatology to countries abroad, leading to significant deprivation of rheumatological service in Central Asian countries. During this time, there was continued growth of various rheumatic diseases (RDs) including rheumatic fever, and musculoskeletal and connective tissue disorders. The medical and social burden of RDs imposed on society was strongly underestimated until recent times. There is an urgent need to define the epidemiology of RDs and their impact on the quality of life of people afflicted by these conditions, and to improve the diagnostics and treatment of these conditions.

National independence and nonproliferation in the new states of Central Asia

Energy Technology Data Exchange (ETDEWEB)

Gleason, G.

1993-12-01

Five independent states emerged in Central Asia from the breakup of the USSR. One of these states, Kazakhstan, possesses nuclear weapons. The other four of these states, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, are not known to possess nuclear weapons, however they occupy a geostrategic position which makes them important to non-proliferation efforts. The present report profiles the capabilities and intentions of these four Central Asian states. The analysis of capabilities suggests that none of these states has the capability to develop a usable nuclear weapon. However, all of these countries-- especially Uzbekistan--have components of the old Soviet nuclear weapons complex which are now orphans. They have no use for these facilities and must either re-profile them, destroy them, or transfer them. The analysis of intentions suggests that the dynamics of national independence have created a situation in which Uzbekistan has hegemonic designs in the region. Implications for retarding nuclear proliferation in the Central Asian region are examined. Opportunities for outside influence are assessed.

Full Text Available This paper investigates the formation and use of water resources in Tajikistan. The natural and geographic conditions as well as distribution of water resources across the economic regions are analyzed. It is stressed that after breakup of the Soviet Union the water use issues in Central Asia have acquired the dimensions of the interstate economic and political problems. Demographic growth, activation of desertification, global warming make most relevant the issue of equitable redistribution of water resources as the most valuable resource for economy.

Two main tasks are to be implemented for elaboration of the governmental water distribution criteria in Central Asia: 1 -development of the common methodological basis for the intergovernmental water distribution; and 2 - to reopen and continue both theoretical and experimental researches of various aspects of the wastewater reuse. The prospects of socio economic development of all Central Asian countries are substantially defined by the water resources availability. The water resources of Central Asia belong, mainly, watersheds of the Syr-Darya and Amu Darya rivers. The basic flow of Amu Darya is formed in territory of Tajikistan. Then the Amu Darya river proceeds along border of Afghanistan with Uzbekistan, crosses Turkmenistan and again comes back to Uzbekistan and then runs into the Aral Sea. The Syr-Darya is second river on the water discharge and is first river on length in Central Asia. The basic flow of Syr Darya is formed in territory of Kyrgyzstan. Then the Syr-Darya river crosses of Uzbekistan and Tajikistan and runs into the Aral Sea in territory of Kazakhstan. During the Soviet Union the water resources of two river watersheds were divided among the Central Asian republics on the basis of the general plans developed by the center in Moscow. In the beginning of 90s years, after taking of sovereignty by the former Soviet republics, the unified control system of water resources management was abolished and the various approaches to its transformation caused by features of the national economy developing, elected models of transition from command to market mechanisms of economic activity, and also specificity of political and social processes in each of the states of region were planned. The distinctions of modern priorities of economic development of the states of region have generated the contradiction of interests in the intergovernmental water distribution that can in the long term become complicated even more in connection with the increasing of water

Afghanistan in the whirlwind of US-Russia rivalry in Central Asia

Full Text Available Afghanistan has been the political and military focal points of the United States (US and Russia (formerly the Soviet Union for over a half a century. Initially, from the 1950s through to the 1970s, the superpowers competed for influence through educational, economic and technical development projects. They used their international development aid as a strategic tool to penetrate the country’s political elite circles to create a space for their political and strategic influence. The nature of development aid then changed to a series of proxy military conflicts throughout the 1980s, which also changed the fate of Afghanistan from that of a developing to that of a conflict country. The current US occupation of Afghanistan (October 2001-present is the latest in the cycle of conflict and rivalry between the US and Russia in Afghanistan and Central Asia. Against this background, this article presents an analysis of how (i the US and Russia create a context and a situation in which they develop, advance, and implement their political and military discourses and strategic concepts, intending to influence each other’s areas of strategic interests; (ii the different components of conflicts and violence are interconnected with one another; and (iii their rivalry for strategic influence in Afghanistan and the broader region of Central Asia triggered a cycle of conflict and a series of continuing proxy wars in Afghanistan. This article applies Johan Galtung’s theories of conflicts as the broader theoretical framework. The developed framework combines Galtung’s three theories of conflict, namely the ABC triangle of conflict, triangle of violence and triangle of peace strategy (Galtung, 1967, 1996. The findings of this article demonstrate that both the US and Russia fight each other in Afghanistan as well as in the wider Central Asia region by supporting and maintaining their satellite countries and periphery elites in power and negotiate each other�

Energy in Asia. An Outline of Some Strategic Energy Issues in Asia

The Asian countries are expected to generate 45% of the world energy consumption and Japan is the absolutely greatest consumer in Asia, but China is the country that will be most important as a new consumer on the world energy markets. China, like India and later possibly even Japan try to change to natural gas as a source of energy as much as possible. This is causing a competition about the resources that can be reached by pipelines for gas, which in practice means those in Russia and Central Asia. Russia is trying to control the gas in Central Asia. The competition is also increasing about oil. China is becoming heavily dependent on Muslim countries in the Middle East and Central Asia. This also leads to an effort to increase the safety along the sea lanes, which may collide with the interests of other countries. Territorial conflicts with gas and oil as underlying elements exist in Asia. USA is a player on the energy market, who is using military means as well, but it is possible that in the short perspective, the American acting may not seriously disturb European interests. In the long term perspective, however, the American activity can cause potential conflicts between USA and the Muslim world, that also affects the relations between Europe and its Muslim neighbours. China and other Asian countries may choose a more pro-islamic line of policy in order to gain advantages in the competition about oil and gas. Europe (and Sweden) ought not to wait until the countries of Asia have finalised their negotiations with Russia and Central Asia about access to resources of natural gas but instead form a clear strategy for negotiations built on its own present demand and act accordingly

Tree Shelterbelts as an Element to Improve Water Resource Management in Central Asia

Directory of Open Access Journals (Sweden)

Niels Thevs

2017-10-01

Full Text Available In Central Asia, agriculture, notably irrigated agriculture, is the largest water consumer. Currently, flood and furrow irrigation are the dominant irrigation methods in Central Asia, in particular in the post-Soviet countries. Against the background of current and increasing competition for water—e.g., through reduced river runoffs in the course of climate change—water consumption of agriculture needs to be reduced. On the field plot level, improved irrigation technologies, like drip irrigation or plastic mulch, can reduce water consumption substantially. Alternatively, tree lines as wind breaks (shelterbelts also can reduce crop water consumption, as shown by research from many drylands around the world. As previous research has concentrated on crop water consumption and not on tree water consumption, this paper brings the two together, in order to approach a more holistic picture, in how far shelterbelt systems, including the trees, may have the potential to save water or not. Crop water consumption was assessed through the Penman–Monteith approach for corn, wheat, potato, barley, and pear under open field conditions and under an assumed influence of a tree shelterbelt. Tree water consumption was investigated through sap flow measurements. Crop water consumption was reduced by 10–12% under influence of a shelterbelt compared to open field conditions. When water consumption of shelterbelts was added, a slight reduction of water consumption of the whole crop-shelterbelt system was found for corn, potato, and pear under the assumption 25 ha (500 × 500 m field sizes. Under an assumption of 4 ha (200 × 200 m field size, water consumption of the whole crop-shelterbelt system was higher for all crops investigated except for pear. The results suggest that shelterbelts may play a role in improving water resource management in Central Asia in the context of water demanding crops, like corn or cotton. In further research, other effects of

Anthropogenic emissions of the toxic heavy metal mercury (Hg) have substantially increased atmospheric Hg levels during the 20th century compared to preindustrial times. However, on a regional scale, atmospheric Hg concentration or deposition trends vary to such an extent during the industrial period that the consequences of recent Asian emissions on atmospheric Hg levels are still unclear. Here we present a 320 year Hg deposition history for Central Asia, based on a continuous high-resolution ice-core Hg record from the Belukha glacier in the Siberian Altai, covering the time period 1680-2001. Hg concentrations and deposition fluxes start rising above background levels at the beginning of the 19th century due to emissions from gold/silver mining and Hg production. A steep increase occurs after the 1940s culminating during the 1970s, at the same time as the maximum Hg use in consumer products in Europe and North America. After a distinct decrease in the 1980s, Hg levels in the 1990s and beginning of the 2000s return to their maximum values, which we attribute to increased Hg emissions from Asia. Thus, rising Hg emissions from coal combustion and artisanal and small-scale gold mining (ASGM) in Asian countries determine recent atmospheric Hg levels in Central Asia, counteracting emission reductions due to control measures in Europe and North America.

We present results of the impact of climate change on the agricultural output in Central Asia (CA) since 1991. While profit-maximizing farmers in the market based economies would be expected to change their cropping patterns fairly fast in response to climate change, we do not expect that to happen in the CA region that was for a long time driven by Soviet production plans with a limited room for personal choice. We explore the relationship between the agricultural productivity (measured by the actual output) and the variations in average monthly temperatures during growing seasons and precipitation. The climate data for Central Asia are generated using the Weather Research (WRF) Model for 1985-2012. We make use of data on air temperature on 2m height, C, and total precipitation. The data on the agricultural production comes from the State Statistical Agencies of the three Central Asian countries: Kazakhstan, Kyrgyzstan and Tajikistan. Data on agricultural production for Turkmenistan and Uzbekistan are not available from online government sources. We model the agricultural production as a function of annual realization of weather in a specific region. This economic approach includes converting daily temperature into degree days, which represents heating units. The two key weather variables are a measure of heat (degree days) and total precipitation in the growing season, April 1st to October 30th. Preliminary regression results estimated for Kazakhstan, indicate that degree days during growing season is negatively and total precipitation is positively associated with the agricultural output. Both coefficients are not statistically significant. Further analysis will include data from other countries and also by the region.

Full Text Available in accordance with the article, 11 deposits coal on the territory of Tuva are accounted by State Reserves Register of the Russian Federation, the total profitable reserves are estimated at 1,12 billion tons whereof 936.6 thousand tons are dealt with as coking coals. The vast majority of explored deposits of coals of the republic are concentrated in the Ulugh-Khem basin, the total projected resources of which exceed 20 bill.t. It is substantiated that coking coal of the Ulugh-Khem basin is the most competitive resource of Tyva Republic. Low ash content, excellent caking index, low sulfur and phosphorus in coking coal of ranks GG and GZh indicate their high quality, according to these characteristics GG, GZh coal ranks take precedence over Kuznetsk and Pechora coals. About 70 bill.t of coking coal are annually mined in Russia, but there is a deficit on certain coal ranks. It is primarily related to internal prices increase for coking coal in Russia. According to forecasts of researchers coal deficit will rise up to 15–17 bill.t in the country.

Arid areas play a significant role in the global nitrogen cycle. Dry and wet deposition of inorganic nitrogen (N) species were monitored at one urban (SDS) and one suburban (TFS) site at Urumqi in a semi-arid region of central Asia. Atmospheric concentrations of NH3, NO2, HNO3, particulate ammonium and nitrate (pNH4 (+) and pNO3 (-)) concentrations and NH4-N and NO3-N concentrations in precipitation showed large monthly variations and averaged 7.1, 26.6, 2.4, 6.6, 2.7 µg N m(-3) and 1.3, 1.0 mg N L(-1) at both SDS and TFS. Nitrogen dry deposition fluxes were 40.7 and 36.0 kg N ha(-1) yr(-1) while wet deposition of N fluxes were 6.0 and 8.8 kg N ha(-1) yr(-1) at SDS and TFS, respectively. Total N deposition averaged 45.8 kg N ha(-1) yr(-1)at both sites. Our results indicate that N dry deposition has been a major part of total N deposition (83.8% on average) in an arid region of central Asia. Such high N deposition implies heavy environmental pollution and an important nutrient resource in arid regions.

Influences of deglaciation on the river run-off in Central Asia

G. E. Glazyrin

2013-01-01

Full Text Available Glaciers form a great deal of runoff of rivers in Central Asia. It is clear that amount of melted water directly depends on total area of glaciers in the river basins – their glaciation. It is well known that at present the area quickly reduces. The complete inventory of glaciers was performed in former Soviet Union in the middle of last century. Airphoto images were used as a basis for our calculations. The inventory was repeated later for several river basins using airphoto- and space images. Unfortunately only three inventories is performed in several river basins for the last half of XX century. Amount of water, coming to a river network from glaciers, can be divided into two parts. The first is usual annual melting. It exists under stationary glaciation condition. The second, being part of the first, is caused by reduction of the glaciation volume. It can be negative in some years when glaciers volume is increasing as a result of favorable meteorological conditions. In these cases the part of water containing in seasonal snow cover does not go to river network. Two components of the glacial feeding were calculated for six rivers located in various regions of Central Asia. It is shown that present day glaciers reduction does not lead to disastrous consequences for river run-off. It leads only to the changes of annual distribution in the run-off. The results should be considered as preliminary because of low accuracy of hydrometeorolological data and number of admissions during calculation.

Genotyping and phylogenetic analysis of Yersinia pestis by MLVA: insights into the worldwide expansion of Central Asia plague foci.

Directory of Open Access Journals (Sweden)

Yanjun Li

Full Text Available BACKGROUND: The species Yersinia pestis is commonly divided into three classical biovars, Antiqua, Medievalis, and Orientalis, belonging to subspecies pestis pathogenic for human and the (atypical non-human pathogenic biovar Microtus (alias Pestoides including several non-pestis subspecies. Recent progress in molecular typing methods enables large-scale investigations in the population structure of this species. It is now possible to test hypotheses about its evolution which were proposed decades ago. For instance the three classical biovars of different geographical distributions were suggested to originate from Central Asia. Most investigations so far have focused on the typical pestis subspecies representatives found outside of China, whereas the understanding of the emergence of this human pathogen requires the investigation of strains belonging to subspecies pestis from China and to the Microtus biovar. METHODOLOGY/PRINCIPAL FINDINGS: Multi-locus VNTR analysis (MLVA with 25 loci was performed on a collection of Y. pestis isolates originating from the majority of the known foci worldwide and including typical rhamnose-negative subspecies pestis as well as rhamnose-positive subspecies pestis and biovar Microtus. More than 500 isolates from China, the Former Soviet Union (FSU, Mongolia and a number of other foci around the world were characterized and resolved into 350 different genotypes. The data revealed very close relationships existing between some isolates from widely separated foci as well as very high diversity which can conversely be observed between nearby foci. CONCLUSIONS/SIGNIFICANCE: The results obtained are in full agreement with the view that the Y. pestis subsp. pestis pathogenic for humans emerged in the Central Asia region between China, Kazakhstan, Russia and Mongolia, only three clones of which spread out of Central Asia. The relationships among the strains in China, Central Asia and the rest of the world based on the MLVA

Central Asia is a vast geographic region that includes five former Soviet Union republics: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The region has a unique infectious disease burden, and a history that includes Silk Road trade routes and networks that were part of the anti-plague and biowarfare programs in the former Soviet Union. Post-Soviet Union biosurveillance research in this unique area of the world has met with several challenges, including lack of funding and resources to independently conduct hypothesis driven, peer-review quality research. Strides have been made, however, to increase scientific engagement and capability. Kazakhstan and Kyrgyzstan are examples of countries where biosurveillance research has been successfully conducted, particularly with respect to especially dangerous pathogens. In this review, we describe in detail the successes, challenges, and opportunities of conducting biosurveillance in Central Asia as exemplified by our recent research activities on ticks and tick-borne diseases in Kazakhstan and Kyrgyzstan.

Full Text Available The paper focuses on the study of the of impact ethnic, religious, civil and Russian identities, ethnic stereotypes on the strategies of acculturation and on the adaptation of migrants from Central Asia in the Moscow region. Representatives of two ethnic groupsparticipated in the research: 105 Uzbeks and 96 Tajiks (N= 201. The methods of the study included the scales of acculturation strategies, ethnic and national identities from the MIRIPS (Mutual Intercultural Relations in Plural Societies project questionnaire. The results of path analysis in AMOS program showed that integration and assimilation are the most successful strategies for migrants from Central Asia: integration contributed to self-esteem, while assimilation promoted life satisfaction. Integration is basically determined by ethnic and Russian identities, whereas assimilation is determined mostly by identification with the country of origin and by Russian identity as well as by the negative impact of ethnic identity. Separation and marginalization do not contribute to self-esteem of the migrants; however, positive heterostereotype of the Russians and Russian national identity prevent the migrants from choosing separation and marginalization. The choice of strategy is largely affected by religious identity. Expressed religious identity has a negative impact on the socio-cultural adaptation of the migrants from Central Asia in the Moscow region.

Central Asia has one of the world's highest levels of earthquake hazard, owing to its exceptionally high deformation rates. Moreover, vulnerability to natural disasters in general is increasing, due to rising populations and a growing dependence on complex lifelines and technology. Therefore, there is an urgent need to undertake seismic hazard and risk assessment in this region, while at the same time improving upon existing methodologies, including the consideration of temporal variability in the seismic hazard, and in structural and social vulnerability. Over the last few years, the German Research Center for Geosciences (GFZ), in collaboration with local partners, has initiated a number of scientific activities within the framework of the Global Change Observatory Central Asia (GCO-CA). The work is divided into projects with specific concerns: - The installation and maintenance of the Central-Asian Real-time Earthquake MOnitoring Network (CAREMON) and the setup of a permanent wireless mesh network for structural health monitoring in Bishkek. - The TIPAGE and TIPTIMON projects focus on the geodynamics of the Tien-Shan, Pamir and Hindu Kush region, the deepest and most active intra-continental subduction zone in the world. The work covers time scales from millions of years to short-term snapshots based on geophysical measurements of seismotectonic activity and of the physical properties of the crust and upper mantle, as well as their coupling with other surface processes (e.g., landslides). - Existing risk analysis methods assume time-independent earthquake hazard and risk, although temporal changes are likely to occur due to, for example, co- and post-seismic changes in the regional stress field. We therefore aim to develop systematic time-dependent hazard and risk analysis methods in order to undertake the temporal quantification of earthquake activity (PROGRESS). - To improve seismic hazard assessment for better loss estimation, detailed site effects studies

Due to lack of reliable proxies from the Westerlies-dominant region, the strength change of Northern Hemisphere Westerlies remains poorly understood. The aim of this study is to provide a reliable paleoclimatic proxy about the Northern Hemisphere Westerlies change. Here we report a 30.7 m thick loess section from the Ili basin directly controlled by the Westerlies. Based on optically stimulated luminescence (OSL) and high resolution grain-size records, we reconstruct the change history of the Westerlies strength during the last glacial period (mainly Marine Isotope Stages 2, MIS2), being similar with the Westerlies index recorded in the Qinghai Lake sediments. Within error limits, all ages are in stratigraphic order. We further compare the climatic records among the Ili loess, Qinghai Lake and the NGRIP, their similarity shows a good climatic coupling relationship among the Central Asia, East Asia and the North Atlantic, and the Westerlies plays a critical influence in transporting the North Atlantic signal to Central and East Asia.

Full Text Available DE L’HORIZON MOYEN A L’HORIZON RECENT SUR LA COTE CENTRALE : LE CAS DE LA VALLEE DE ASIA. La vallée de Asia, située à quelque 100 km au sud de Lima, a joué un rôle important durant l’Horizon moyen. En effet, les contextes funéraires de la Huaca Malena et les textiles élaborés qui en sont issus, suggèrent d’étroites relations avec Huari, Pachacamac, et les côtes centrale et nord. L’étude des textiles nous permet de voir que la transition de l’Horizon moyen à la période Intermédiaire récent se marque par une croissance des relations avec la côte centrale. Selon les données ethnohistoriques, la vallée de Asia était durant la période Intermédiaire récent habitée par les Coyallo, qui versaient tribut à Pachacamac. À l’Horizon récent, les Incas construisirent d’importants centres administratifs dans la vallée, et durant cette période le matériel céramique montre de fortes relations avec les styles des vallées voisines au nord, comme Mala, Chilca, et la côte aux alentours de Lima. El valle de Asia, situado a 100 kilómetros al sur de Lima, jugó un rol de importancia durante el Horizonte Medio. En efecto, los contextos funerarios de Huaca Malena, así como los finos textiles que los acompañan indican una fuerte relación con Wari, Pachacamac, la Costa Central y la Costa Norte. De acuerdo con la evidencia textil, el tránsito del Horizonte Medio al periodo Intermedio Tardío incrementó las relaciones con la costa central. Para el periodo Intermedio Tardío, de acuerdo a la información etnohistórica, el valle estuvo habitado por los coayllo, quienes tributaban a Pachacamac. Durante el Horizonte Tardío, los incas construyen importantes centros administrativos en el valle, y la cerámica durante este periodo se relacionó fuertemente con los estilos propios de los vecinos valles norteños de Mala, Chilca y la costa de Lima.

Central Asia is a region that has a large land mass, yet meteorological stations in this area are relatively scarce. To address this data issues, in this study, we selected two reanalysis datasets (the ERA40 and NCEP/NCAR) and downscaled them to 40 × 40 km using RegCM. Then three gridded datasets (the CRU, APHRO, and WM) that were extrapolated from the observations of Central Asian meteorological stations to evaluate the performance of RegCM and analyze the spatiotemporal distribution of precipitation and air temperature. We found that since the 1960s, the air temperature in Xinjiang shows an increasing trend and the distribution of precipitation in the Tianshan area is quite complex. The precipitation is increasing in the south of the Tianshan Mountains (Southern Xinjiang, SX) and decreasing in the mountainous areas. The CRU and WM data indicate that precipitation in the north of the Tianshan Mountains (Northern Xinjiang, NX) is increasing, while the APHRO data show an opposite trend. The downscaled results from RegCM are generally consistent with the extrapolated gridded datasets in terms of the spatiotemporal patterns. We believe that our results can provide useful information in developing a regional climate model in Central Asia where meteorological stations are scarce.

Esophageal squamous cell carcinoma (ESCC) shows geographic variations in incidence, with high incidences (>50/10 5 person-years) in central Asia, including North Eastern Iran (Golestan) and Northern India (Kashmir). In contrast to Western countries, smoking does not appear to be a significant risk factor for ESCC in central Asia. In lung adenocarcinoma, activating mutations in the gene encoding epidermal growth factor receptor (EGFR) are frequent in tumors of never smokers of Asian origin, predicting therapeutic sensitivity to Egfr-targeting drugs. In this study 152 cases of histologically confirmed ESCC from Iran (Tehran and Golestan Province) and North India (Kashmir Valley) have been analyzed for EGFR mutation by direct sequencing of exons 18–21. Egfr protein expression was evaluated by immunohistochemistry in 34 samples from Tehran and HER2 mutations were analyzed in 54 cases from Kashmir. A total of 14 (9.2%) EGFR variations were detected, including seven variations in exons. Among those, four (2.6%) were already documented in lung cancers, two were reported as polymorphisms and one was a potentially new activating mutation. All but one variation in introns were previously identified as polymorphisms. Over-expression of Egfr was detected in 22/34 (65%) of tested cases whereas no HER2 mutation was found in 54 cases from Kashmir. Overall, EGFR mutations appear to be a rare event in ESCC in high incidence areas of central Asia, although a very small proportion of cases may harbor mutations predicting sensitivity to anti-Egfr drugs

Capsule: We describe ecological factors associated with movements of a globally declining raptor species, the Eastern Imperial Eagle Aquila heliaca.Aims: To describe the movements, habitat associations and resource selection of Eastern Imperial Eagles marked in Central Asia.Methods: We used global positioning system (GPS) data sent via satellite telemetry devices deployed on Eastern Imperial Eagles captured in Kazakhstan to calculate distances travelled and to associate habitat and weather variables with eagle locations collected throughout the annual cycle. We also used resource selection models to evaluate habitat use of tracked birds during autumn migration. Separately, we used wing-tagging recovery data to broaden our understanding of wintering locations of eagles.Results: Eagles tagged in Kazakhstan wintered in most countries on the Arabian Peninsula, as well as Iran and India. The adult eagle we tracked travelled more efficiently than did the four pre-adults. During autumn migration, telemetered eagles used a mixture of vegetation types, but during winter and summer, they primarily used bare and sparsely vegetated areas. Finally, telemetered birds used orographic updrafts to subsidize their autumn migration flight, but they relied on thermal updrafts during spring migration.Conclusion: Our study is the first to use GPS telemetry to describe year-round movements and habitat associations of Eastern Imperial Eagles in Central Asia. Our findings provide insight into the ecology of this vulnerable raptor species that can contribute to conservation efforts on its behalf.

Reinhardt, Katja; Samimi, Cyrus

2017-04-01

For the assessment of the global climate change and its consequences, the results of computer based climate models are of central importance. The quality of these results and the validity of the derived forecasts are strongly determined by the quality of the underlying climate data. However, in many parts of the world high resolution data are not available. This is particularly true for many regions in Central Asia, where the density of climatological stations has often to be described as thinned out. Due to this insufficient data base the use of statistical methods to improve the resolution of existing climate data is of crucial importance. Only this can provide a substantial data base for a well-founded analysis of past climate changes as well as for a reliable forecast of future climate developments for the particular region. The study presented here shows a comparison of different interpolation methods for the wind components u and v for a region in Central Asia with a pronounced topography. The aim of the study is to find out whether there is an optimal interpolation method which can equally be applied for all pressure levels or if different interpolation methods have to be applied for each pressure level. The European reanalysis data Era-Interim for the years 1989 - 2015 are used as input data for the pressure levels of 850 hPa, 500 hPa and 200 hPa. In order to improve the input data, two different interpolation procedures were applied: On the one hand pure interpolation methods were used, such as inverse distance weighting and ordinary kriging. On the other hand machine learning algorithms, generalized additive models and regression kriging were applied, considering additional influencing factors, e.g. geopotential and topography. As a result it can be concluded that regression kriging provides the best results for all pressure levels, followed by support vector machine, neural networks and ordinary kriging. Inverse distance weighting showed the worst

Holocene climate variability in arid Central Asia as revealed from high-resolution sedimentological and geochemical analyses of laminated sediments from Lake Chatyr Kol (Central Tian Shan, Kyrgyzstan)

A pronounced trend from a predominantly wet climate during the early Holocene towards significantly drier conditions since the mid-Holocene, mainly attributed to the weakening of the Asian summer monsoon (ASM), is documented in numerous palaeoclimate records from the monsoon-influenced parts of Asia, e.g. the Tibetan Plateau and north- and southeastern China. In contrast, climate in the adjacent regions of mid-latitude arid Central Asia, located north and northwest of the Tibetan Plateau, is supposed to have been characterized by pronounced dry conditions during the early Holocene, wet conditions during the mid-Holocene and a rather moderate drying during the late Holocene, which is mainly attributed to the complex interplay between the mid-latitude Westerlies and the ASM. However, although mid-latitude Central Asia thus might represent a key region for the understanding of teleconnections between the ASM system and the Westerlies, knowledge about past climate development in this region is still ambiguous due to the limited number of high-resolution palaeoclimate records. Hence, new well-dated and highly resolved palaeoclimate records from this region are expected to provide important information about spatio-temporal changes in the regional interplay between Westerlies and ASM and thus aid the understanding of global climate teleconnections. As a part of the project CADY (Central Asian Climate Dynamics), aiming at reconstructing past climatic and hydrological variability in Central Asia, a sediment core of about 6.25 m length has been recovered from alpine Lake Chatyr Kol (40°36' N, 75°14' E, 3530 m a. s. l., surface area ~170 km2, maximum depth ~20 m), located in the Central Tian Shan of Kyrgyzstan. Sediment microfacies analysis on large-scale petrographic thin sections reveals continuously sub-mm scale laminated sediments throughout the record except for the uppermost ca. 60 cm.

The Working Party on Gas of the United Nations Economic Commission for Europe (UN/ECE), at its sixth session in 1996, decided to undertake a study on 'Underground gas storage in Europe and Central Asia'. The study was launched by the Working Party on Gas in the recognition of the role of underground gas storage (UGS) in the creation of unified European gas market, its liberalization, security of gas supply and cooperation among gas enterprises. The data analysed by the study was collected through the comprehensive questionnaire, circulated among gas companies/organizations of the ECE member-countries. To carry out the study, a special Ad Hoc Group of Experts, representing leading gas companies of the region, was set up. The study deals with a wide range of issues related to the underground storage of gas, such as current status of UGS in Europe and Central Asia, new and emerging technologies, new and existing UGS projects, regulatory framework, cost of storage in USA and in Europe, future gas markets development. An attempt was also made to identify the UGS facilities that play (and could provide in the future) the international contract border services. (authors)

Estimating continental water storage variations in Central Asia area using GRACE data

2014-01-01

The goal of GRACE satellite is to determine time-variations of the Earth's gravity, and particularly the effects of fluid mass redistributions at the surface of the Earth. This paper uses GRACE Level-2 RL05 data provided by CSR to estimate water storage variations of four river basins in Asia area for the period from 2003 to 2011. We apply a two-step filtering method to reduce the errors in GRACE data, which combines Gaussian averaging function and empirical de-correlation method. We use GLDAS hydrology to validate the result from GRACE. Special averaging approach is preformed to reduce the errors in GLDAS. The results of former three basins from GRACE are consistent with GLDAS hydrology model. In the Tarim River basin, there is more discrepancy between GRACE and GLDAS. Precipitation data from weather station proves that the results of GRACE are more plausible. We use spectral analysis to obtain the main periods of GRACE and GLDAS time series and then use least squares adjustment to determine the amplitude and phase. The results show that water storage in Central Asia is decreasing

Drought occurrence and duration in central Asia are of important socioeconomic, ecological, and geophysical significance and have received increasing research attention in recent years. Understanding long-term drought trends and their driving forces require reliable records of past drought variability with broad spatial representativeness. Here, we compiled four tree-ring δ18O records from eastern central Asia (ECA) and composited them into a drought-sensitive proxy to explore regional ECA moisture variations over the past 301 years (1710-2010 CE). A robust regional standardized precipitation-evapotranspiration index (SPEI) reconstruction was established based on the tree-ring cellulose δ18O fractionation mechanism and statistically significant proxy-climate relationships. We identified prominent droughts in 1710-1770, 1810-1830, and the beginning of the twenty-first century, and a regime shift to a persistently wet period from the 1880s to 2000. Our reconstruction reveals the impact of drought and pluvial patterns on the decline of Zhungar Empire, and on historical agricultural and socio-economical activities, including increased migration into ECA during the 1770-1800 pluvial. Our findings also suggest that wet conditions in the twentieth century in ECA were related to a strengthening of the westerly circulation and thus shed light on large-scale atmospheric circulation dynamics in central Asia.

Overview of Iodine Deficiency Prevention Strategies in the South-Eastern Europe and Central Asia Region: 2009–2016

Full Text Available Universal salt iodization (USI strategies gained strong momentum in countries of the Southern Europe and Central Asia (SECA region during the 2000–2009 decade. By the end of the first decade, several countries in the region had already reached the goal of optimum iodine nutrition; other countries were quickly approaching this goal, and in only a few countries the progress toward USI had remained slow. This paper reports an overview of the two Sub-Regional workshops (for countries of Eastern Europe and Central Asia and South-Eastern Europe conducted in 2015 and 2016. Both workshops demonstrate that the SECA region remains on track in the pursuit of USI for sustainable IDD elimination. Notwithstanding the noted imperfections, none of the data or information from countries of the region suggested that the conquest of iodine deficiency is seriously threatened. However, more efforts should be made to develop and streamline USI strategies in Russia and Ukraine, two major countries that are lagging behind.

Full Text Available The Soil and Water Assessment Tool (SWAT was used to simulate five glacierized river basins that are global in coverage and vary in climate. The river basins included the Narayani (Nepal, Vakhsh (Central Asia, Rhone (Switzerland, Mendoza (Central Andes, Argentina, and Central Dry Andes (Chile, with a total area of 85,000 km2. A modified SWAT snow algorithm was applied in order to consider spatial variation of associated snowmelt/accumulation by elevation band across each subbasin. In previous studies, melt rates varied as a function of elevation because of an air temperature gradient while the snow parameters were constant throughout the entire basin. A major improvement of the new snow algorithm is the separation of the glaciers from seasonal snow based on their characteristics. Two SWAT snow algorithms were evaluated in simulation of monthly runoff from the glaciered watersheds: (1 the snow parameters are lumped (constant throughout the entire basin and (2 the snow parameters are spatially variable based on elevation bands of a subbasin (modified snow algorithm. Applying the distributed SWAT snow algorithm improved the model performance in simulation of monthly runoff with snow-glacial regime, so that mean RSR decreased to 0.49 from 0.55 and NSE increased to 0.75 from 0.69. Improvement of model performance was negligible in simulations of monthly runoff from the basins with a monsoon runoff regime.

Full Text Available Airborne mineral dust is thought to have a significant influence on the climate through absorbing and scattering both shortwave and longwave radiations and affecting cloud microphysical processes. However, a knowledge of long-term dust emissions is limited from both temporal and spatial perspectives. Here, we have developed a quantitative climatology: the column-integrated mass of the dust aerosol loading in Central Asia by incorporating the dust module (DuMo into the Weather Research and Forecasting coupled with Chemistry (WRF-Chem model and accounting for regional climate and Land-Cover and Land-Use Changes for the 1950-2010 period in April. This data set is lowly to moderately correlated (0.22-0.48 with the satellite Aerosol Optical Depth in April of the 2000s and lowly correlated (0.02-0.11 with the Absorbing Aerosol Index in April of the 1980s, 1990s, and 2000s. The total dust loading is approximately 207.85 Mton per month in April during the recent decade (2000-2014 over dust source regions. Although only the month of April was simulated, results suggest that trends and magnitudes are captured well, using the WRF-Chem-DuMo.

RUSSIAN PERIODICALS AT THE TURN OF THE 19TH -20TH CENTURIESON RUSSIAN MIGRANTS’ SOCIOCULTURAL ADAPTATION IN CENTRAL ASIA

2017-12-01

Full Text Available In the Russian historiography, the views of the publicists of the early 20th century of the Russian colonists’ life in Central Asia aren’t duly highlighted. The novelty and aim of the research consist in revealing the general and particular in the Russian periodicals’ percep-tion of the colonization of Turkestan, in determining their ideological bent. The authors have discovered that all the reviewed periodicals were adherents of Central Asia colonization. They supported the imperial policy of the government with minor reserva-tions. Most publicists noted that the settling of colonists depended on the actions of the central government, which insuffi ciently took into account the local conditions. However, publicists differed in the choice of the main direction and in the assessments of the value of colonists’ adaptation activity; they proposed various ways of developing the intercultural dialogue.The authors come to the conclusions that liberal periodicals paid special attention to the economic activities of Russian immigrants, assessing the degree of their adaptation by the level of well-being achieved. The Narodnik periodicals considered migrants as a part of the peasant world of Russia. They were concerned, above all, about the colonists’ commu-nity, which they considered an effective means of adaptation, preserving the culture and moral qualities of the Russians. Probably, they considered it a pledge of building fair relations with the local population. Conservative and offi cial publicists viewed Russian immigrants primarily as support of the Russian government in Central Asia. That is why they paid special attention to the preservation of assimilation qualities of the Russians, the loss of which could become, in their view, an obstacle to the strengthening of the empire positions in the region.

Empirically derived coda source spectra provide unbiased, absolute moment magnitude (Mw) estimates for events that are normally too small for accurate long-period waveform modeling. In this study, we obtain coda-derived source spectra using data from Central Asia (Kyrgyzstan networks - KN and KR, and Tajikistan - TJ) and South Korea (Korea Meteorological Administration, KMA). We used a recently developed coda calibration module of Seismic WaveForm Tool (SWFT). Seismic activities during this recording period include the recent Gyeongju earthquake of Mw=5.3 and its aftershocks, two nuclear explosions from 2009 and 2013 in North Korea, and a small number of construction and mining-related explosions. For calibration, we calculated synthetic coda envelopes for both P and S waves based on a simple analytic expression that fits the observed narrowband filtered envelopes using the method outlined in Mayeda et al. (2003). To provide an absolute scale of the resulting source spectra, path and site corrections are applied using independent spectral constraints (e.g., Mw and stress drop) from three Kyrgyzstan events and the largest events of the Gyeongju sequence in Central Asia and South Korea, respectively. In spite of major tectonic differences, stable source spectra were obtained in both regions. We validated the resulting spectra by comparing the ratio of raw envelopes and source spectra from calibrated envelopes. Spectral shapes of earthquakes and explosions show different patterns in both regions. We also find (1) the source spectra derived from S-coda is more robust than that from the P-coda at low frequencies; (2) unlike earthquake events, the source spectra of explosions have a large disagreement between P and S waves; and (3) similarity is observed between 2016 Gyeongju and 2011 Virginia earthquake sequence in the eastern U.S.

The aim of the study was to measure and compare national continuum of HIV care estimates in Europe and Central Asia in three key subpopulations: men who have sex with men (MSM), people who inject drugs (PWID) and migrants. Responses to a 2016 European Centre for Disease Prevention and Control (ECDC) survey of 55 European and Central Asian countries were used to describe continuums of HIV care for the subpopulations. Data were analysed using three frameworks: Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets; breakpoint analysis identifying reductions between adjacent continuum stages; quadrant analysis categorizing countries using 90% cut-offs for continuum stages. Overall, 29 of 48 countries reported national data for all HIV continuum stages (numbers living with HIV, diagnosed, receiving treatment and virally suppressed). Six countries reported all stages for MSM, seven for PWID and two for migrants. Thirty-one countries did not report data for MSM (34 for PWID and 41 for migrants). In countries that provided key-population data, overall, 63%, 40% and 41% of MSM, PWID and migrants living with HIV were virally suppressed, respectively (compared with 68%, 65% and 68% nationally, for countries reporting key-population data). Variation was observed between countries, with higher outcomes in subpopulations in Western Europe compared with Eastern Europe and Central Asia. Few reporting countries can produce the continuum of HIV care for the three key populations. Where data are available, differences exist in outcomes between the general and key populations. While MSM broadly mirror national outcomes (in the West), PWID and migrants experience poorer treatment and viral suppression. Countries must develop continuum measures for key populations to identify and address inequalities. © 2018 British HIV Association.

Grassland degradation and desertification is a complex process, including both state conversion (e.g., grasslands to deserts) and gradual within-state change (e.g., greenness dynamics). Existing studies hardly separated the two components and analyzed it as a whole based on time series vegetation index data, which cannot provide a clear and comprehensive picture for grassland degradation and desertification. Here we propose an integrated assessment strategy, by considering both state conversion and within-state change of grasslands, to investigate grassland degradation and desertification process in Central Asia. First, annual maps of grasslands and sparsely vegetated land were generated to track the state conversions between them. The results showed increasing grasslands were converted to sparsely vegetated lands from 2000 to 2014, with the desertification region concentrating in the latitude range of 43-48° N. A frequency analysis of grassland vs. sparsely vegetated land classification in the last 15 yr allowed a recognition of persistent desert zone (PDZ), persistent grassland zone (PGZ), and transitional zone (TZ). The TZ was identified in southern Kazakhstan as one hotspot that was unstable and vulnerable to desertification. Furthermore, the trend analysis of Enhanced Vegetation Index during thermal growing season (EVI TGS ) was investigated in individual zones using linear regression and Mann-Kendall approaches. An overall degradation across the area was found; moreover, the second desertification hotspot was identified in northern Kazakhstan with significant decreasing in EVI TGS , which was located in PGZ. Finally, attribution analyses of grassland degradation and desertification were conducted by considering precipitation, temperature, and three different drought indices. We found persistent droughts were the main factor for grassland degradation and desertification in Central Asia. Considering both state conversion and gradual within-state change

Caucasus and Central Asia represents regions of high seismic activity, composing a significant part of Alpine-Himalayan continental collision zone. Natural catastrophic events cause significant damage to the infrastructure worldwide, among these approximately ninety percent of the annual loss is due to earthquakes. Monitoring of Seismic Activity in these regions and adequate assessment of Seismic Hazards represents indispensible condition for safe and stable development. Existence of critical engineering constructions in the Caucasus and Central Asia such as oil and gas pipelines, high dams and nuclear power plants dramatically raises risks associated with natural hazards and eliminates necessity of proper monitoring systems. Our initial efforts were focused on areas that we are most familiar; the geophysical community in the greater Caucuses and Central Asia experiencing many of the same problems with the monitoring equipment. As a result, during the past years GMSys2009 was develop at the Institute of Earth Sciences of Ilia State University. Equipment represents a cost-effective, multifunctional Geophysical Data Acquisition System (DAS) to monitor seismic waves propagating in the earth and related geophysical parameters. Equipment best fits local requirements concerning power management, environmental protection and functionality, the same time competing commercial units available on the market. During past several years more than 30 units were assembled and what is most important installed in Georgia, Armenia, Azerbaijan and Tajikistan. GMSys2009 utilizes standard MiniSEED data format and data transmission protocols, making it possible online waveform data sharing between the neighboring Countries in the region and international community. All the mentioned installations were technically supported by the group of engineers from the Institute of Earth Sciences, on site trainings for local personnel in Armenia, Azerbaijan and Tajikistan was provided creating a

Linguistic Phylogenies Support Back-Migration from Beringia to Asia

Sicoli, Mark A.; Holton, Gary

Recent arguments connecting Na-Dene languages of North America with Yeniseian languages of Siberia have been used to assert proof for the origin of Native Americans in central or western Asia. We apply phylogenetic methods to test support for this hypothesis against an alternative hypothesis that Yeniseian represents a back-migration to Asia from a Beringian ancestral population. We coded a linguistic dataset of typological features and used neighbor-joining network algorithms and Bayesian model comparison based on Bayes factors to test the fit between the data and the linguistic phylogenies modeling two dispersal hypotheses. Our results support that a Dene-Yeniseian connection more likely represents radiation out of Beringia with back-migration into central Asia than a migration from central or western Asia to North America.

A mid-Holocene shift from predominantly wet to significantly drier climate conditions, attributed to the weakening of the Asian summer monsoon (ASM), is documented in numerous palaeoclimate records from the monsoon-influenced parts of Asia, e.g. the Tibetan Plateau and north- and southeastern China. In contrast, Holocene climate development in the arid regions of mid-latitude Central Asia, located north and northwest of the Tibetan Plateau, is less well-constrained but supposed to have been influenced by a complex interaction between the mid-latitude Westerlies and the ASM. Hence, well-dated and highly resolved palaeoclimate records from Central Asia might provide important information about spatio-temporal changes in the regional interplay between Westerlies and ASM and thus aid the understanding of global climate teleconnections. As a part of the project CADY (Central Asian Climate Dynamics), aiming at reconstructing past climatic and hydrological variability in Central Asia, several sediment cores were recovered from alpine Lake Son Kol (41° 48'N, 75° 12'E, 3016 m a. s. l.) in the Central Tian Shan of Kyrgyzstan. A radiocarbon-dated sediment sequence of 154.5 cm length, covering approximately the last 6000 years, was investigated by using a multi-proxy approach, including sedimentological, (bio)geochemical, isotopic and micropalaeontological analyses. Preliminary proxy data indicate hydrologically variable but predominantly wet conditions until ca. 5100 cal. a BP, characterized by the deposition of finely laminated organic-carbonatic sediments. In contrast to monsoonal Asia, where a distinct trend towards drier conditions is observed since the mid-Holocene, the hydrologically variable interval at Lake Son Kol was apparently followed by an only short-term dry episode between ca. 5100 and 4200 cal. a BP. This is characterized by a higher δD of the C29 n-alkanes, probably reflecting increased evapotranspiration. Also pollen, diatom and ostracod data point

Full Text Available The pet trade with decapod crustaceans has been considered one of the main pathway of introduction of these animals worldwide. As the leading markets in this regards are the Czech Republic, Germany and the USA. Central Asia is not perceived as an important market with ornamental decapod crustaceans. Despite this assumption, we found at least 16 species of freshwater shrimp, crayfish and crab species pet-traded in the Republic of Kazakhstan, the largest country in this region. Considering computed risk assessment, the origin of particular species, their availability on the market, the probability of establishment and further aspects, we identified two crayfish Procambarus clarkii and Procambarus fallax f. virginalis being the seriously hazardous taxa with high potential to threaten native crayfish species as well as inhabited ecosystems. To prevent their introductions and to minimize the risks of mentioned species, similarly as in the case of European Union, we recommend the total ban of import, trade and keeping of these high-risk taxa within Central Asia.

Meena Singh Roy

2017-10-01

Full Text Available The present article tries to examine India’s initiatives in the region in the context of the emerging regional geo-strategic landscape. With an aim to enhance political, economic and strategic ties, India’s policy towards the region has moved from ‘Look North’ to ‘Connect North’. Notably, the full membership of SCO offers India greater synergies to play a more active role in the region. India is, thus, all set to build more meaningful partnerships with the region in the context of new geo-political changes shaping Central Asia. More importantly, the region is seeking India to play a more active role. It is argued that the beginning of a new era of cooperation initiated by PM Modi can only be sustained if New Delhi continues to implement its various agreements and commitments. While building stronger bilateral ties with the region is important, working closely in the regional groupings will also help address regional economic and security challenges

Full Text Available China´s interests in Central Asia were propelled, with the launching of the initiative “One Belt, One Road”, renamed as “The Belt and Road Initiative”, better known as the New Silk Road. Thanks to the infrastructure investment China will become interconnected with other regions of the world, breaking up its secular isolation and will send its products to the global market more easily by land and sea. One principal question in this revolutionary change has to do with China´s hypothetical second intentions of geopolitical influence on the countries affected by the new routes (countries of transit or final destination. The article tries to answer the following questions: Does the People's Republic of China aim only to revive its internal labour market, reduce its industrial overcapacity and boost its exports? Is globalization coming to an end or is it entering a new phase of interconnectivity? How does this affect the relations between Russia and China in the Asian region?

Could Changing Power Relationships Lead to Better  Water Sharing in Central Asia?

Directory of Open Access Journals (Sweden)

Aibek Zhupankhan

2017-02-01

Full Text Available Even though Central Asia is water rich, water disputes have characterized the region after crumbling of the Soviet Union in 1991. The uneven spatial distribution and complex pattern of transboundary water sources with contrasting national water needs have created an intricate water dilemma. Increasing national water needs, water claims by surrounding countries, uncertainties in renewable water volumes, and effects of climate change will put further strain on the future water use in Central Asia. We argue that the present power distribution with three downstream hegemons (Kazakhstan, Turkmenistan, and Uzbekistan and two upstream much poorer countries with less political influence (Kyrgyzstan and Tajikistan is not likely to lead forward to a greater willingness to share water. We discuss this situation with the analogue Egypt-Sudan-Ethiopia in the Nile Basin. Thus, as in the case of Ethiopia in the Nile Basin, gradually economically stronger upstream countries Kyrgyzstan and Tajikistan due to hydropower development are likely to eventually re-define the hydropolitical map of Central Asia. As in the case of the Nile Basin, a more even power balance between upstream and downstream countries may lead to an improved political structure for a much-needed better collaboration on water issues.

Quantifying the Impacts of Environmental Factors on Vegetation Dynamics over Climatic and Management Gradients of Central Asia

Full Text Available Currently there is a lack of quantitative information regarding the driving factors of vegetation dynamics in post-Soviet Central Asia. Insufficient knowledge also exists concerning vegetation variability across sub-humid to arid climatic gradients as well as vegetation response to different land uses, from natural rangelands to intensively irrigated croplands. In this study, we analyzed the environmental drivers of vegetation dynamics in five Central Asian countries by coupling key vegetation parameter “overall greenness” derived from Moderate Resolution Imaging Spectroradiometer (MODIS Normalized Difference Vegetation Index (NDVI time series data, with its possible factors across various management and climatic gradients. We developed nine generalized least-squares random effect (GLS-RE models to analyze the relative impact of environmental factors on vegetation dynamics. The obtained results quantitatively indicated the extensive control of climatic factors on managed and unmanaged vegetation cover across Central Asia. The most diverse vegetation dynamics response to climatic variables was observed for “intensively managed irrigated croplands”. Almost no differences in response to these variables were detected for managed non-irrigated vegetation and unmanaged (natural vegetation across all countries. Natural vegetation and rainfed non-irrigated crop dynamics were principally associated with temperature and precipitation parameters. Variables related to temperature had the greatest relative effect on irrigated croplands and on vegetation cover within the mountainous zone. Further research should focus on incorporating the socio-economic factors discussed here in a similar analysis.

Asthenospheric counterflows beneath the moving lithosphere of Central and East Asia in the past 90 Ma: volcanic and tomographic evidence

Science.gov (United States)

Rasskazov, Sergei; Chuvashova, Irina; Kozhevnikov, Vladimir

2015-04-01

Asthenospheric counterflows, accompanied motions of the lithosphere in Central and East Asia, are defined on basis of spatial-temporal activity of mantle sources [Rasskazov et al., 2012; Rasskazov, Chuvashova, 2013; Chuvashova, Rasskazov, 2014] and the tomographic model of the Rayleigh wave group velocities [Kozhevnikov et al., 2014]. The opposite fluxes are defined relative to centers of convective instability (low-velocity anomalies), expressed by thinning of the mantle transition layer under Southwestern Gobi (44 °N, 95 °E) and Northern Baikal (52 °N, 108 °E). Cretaceous-Paleogene volcanic fields in Southern Gobi are shifted eastwards relative to the former anomaly over 600 km with the opposite sub-lithospheric flux at depths of 150-300 km. Likewise, the Late Tertiary Vitim volcanic field is shifted relative to the latter anomaly over 100-200 km. We suggest that the Gobi and Baikal asthenospheric counterflows contributed to the rollback mechanism of downgoing slab material from the Pacific under the eastern margin of Asia in the Cretaceous-Paleogene and Early-Middle Miocene. The east-west Gobi reverse flux, caused by differential block motions in front of the Indo-Asian convergence, resulted in the oblique Honshu-Korean flexure of the Pacific slab that propagated beneath the continental margin, while the Japan Sea was quickly opening at about 15 Ma. The Baikal N60°W reverse flux, originated due to oncoming traffic between Eurasia and the Pacific plate, entailed the formation of the Baikal Rift Zone and direct Hokkaido Amur slab flexure [Rasskazov et al., 2004].

Zika virus (ZIKV) is an emerging mosquito-borne virus that was first isolated from a sentinel rhesus monkey in the Zika Forest in Uganda in 1947. In Asia, the virus was isolated in Malaysia from Aedes aegypti mosquitoes in 1966, and the first human infections were reported in 1977 in Central Java, Indonesia. In this review, all reported cases of ZIKV infection in Asia as of September 1, 2016 are summarized and some of the hypotheses that could currently explain the apparently low incidence of Zika cases in Asia are explored.

Climate model performance and change projection for freshwater fluxes: Comparison for irrigated areas in Central and South Asia

2016-03-01

Full Text Available Study region: The large semi-arid Aral Region in Central Asia and the smaller tropical Mahanadi River Basin (MRB in India. Study focus: Few studies have so far evaluated the performance of the latest generation of global climate models on hydrological basin scales. We here investigate the performance and projections of the global climate models in the Coupled Model Intercomparison Project, Phase 5 (CMIP5 for freshwater fluxes and their changes in two regional hydrological basins, which are both irrigated but of different scale and with different climate. New hydrological insights for the region: For precipitation in both regions, model accuracy relative to observations has remained the same or decreased in successive climate model generations until and including CMIP5. No single climate model out-performs other models across all key freshwater variables in any of the investigated basins. Scale effects are not evident from global model application directly to freshwater assessment for the two basins of widely different size. Overall, model results are less accurate and more uncertain for freshwater fluxes than for temperature, and particularly so for model-implied water storage changes. Also, the monsoon-driven runoff seasonality in MRB is not accurately reproduced. Model projections agree on evapotranspiration increase in both regions until the climatic period 2070–2099. This increase is fed by precipitation increase in MRB and by runoff water (thereby decreasing runoff in the Aral Region.

Integrated spatiotemporal characterization of dust sources and outbreaks in Central and East Asia

Science.gov (United States)

Darmenova, Kremena T.

The potential of atmospheric dust aerosols to modify the Earth's environment and climate has been recognized for some time. However, predicting the diverse impact of dust has several significant challenges. One is to quantify the complex spatial and temporal variability of dust burden in the atmosphere. Another is to quantify the fraction of dust originating from human-made sources. This thesis focuses on the spatiotemporal characterization of sources and dust outbreaks in Central and East Asia by integrating ground-based data, satellite multisensor observations, and modeling. A new regional dust modeling system capable of operating over a span of scales was developed. The modeling system consists of a dust module DuMo, which incorporates several dust emission schemes of different complexity, and the PSU/NCAR mesoscale model MM5, which offers a variety of physical parameterizations and flexible nesting capability. The modeling system was used to perform for the first time a comprehensive study of the timing, duration, and intensity of individual dust events in Central and East Asia. Determining the uncertainties caused by the choice of model physics, especially the boundary layer parameterization, and the dust production scheme was the focus of our study. Implications to assessments of the anthropogenic dust fraction in these regions were also addressed. Focusing on Spring 2001, an analysis of routine surface meteorological observations and satellite multi-sensor data was carried out in conjunction with modeling to determine the extent to which integrated data set can be used to characterize the spatiotemporal distribution of dust plumes at a range of temporal scales, addressing the active dust sources in China and Mongolia, mid-range transport and trans-Pacific, long-range transport of dust outbreaks on a case-by-case basis. This work demonstrates that adequate and consistent characterization of individual dust events is central to establishing a reliable

Multiple sclerosis (MS) is one of the most common chronic immune-mediated diseases of the human central nervous system and an important cause of non-traumatic neurologic disability among young population in several countries. Recent reports from East Asia, South East Asia and South Asia have proposed a low to moderate prevalence of MS in these countries. A literature review search was carried out in December 2014 in Medline, Embase, Scopus and Cochrane library to recover original population-based studies on MS epidemiology in East Asia, South East Asia and South Asia countries published between January 1, 1950 and December 30, 2014. We intended search strategies using the key words: multiple sclerosis, prevalence, incidence and epidemiology. Based on our inclusion criteria, 68 epidemiologic studies were included in this systematic review. The most extensively used diagnostic criteria in the studies were McDonald's criteria. Most studies were performed in a multi-center hospital setting. The female to male ratio varied and ranged from 0.7 in India to 9.0 in China. The mean age at disease onset ranged from the lowest age of 25.3 in Iran to the highest age of 46.4 in China. MS prevalence ranged from 0.77 in 100,000 populations in Hong Kong (1999) to 85.80 in 100,000 in Iran (2013). Advances in MS registries around the globe allow nationwide population-based studies and will allow worldly comparisons between the prevalence and incidence in different regions that are provided to monitor estimation. © 2016 S.

Rather,corruption has directconsequences on economic and governance factors, intermediaries that in turn producepoverty. Although corruption is seen inmany countries in the world, it ishigher and widespread in developingcountries. This study investigates relationbetween corruption, poverty, and economic performance by using apanelconsisting of countries in the Eastern Europe and Central Asia countries. It wasshown that corruptionaffected directly economic performance and low economicperformance leads to poverty. Additionally, resultsimply that rules againstcorruption could affect economic growth indirectly through their impact on thelevel ofc orruption.

The U.S. Geological Survey conducted an assessment of resources associated with porphyry copper deposits in the western Central Asia countries of Kyrgyzstan, Uzbekistan, Kazakhstan, and Tajikistan and the southern Urals of Kazakhstan and Russia as part of a global mineral resource assessment. The purpose of the study was to (1) delineate permissive areas (tracts) for undiscovered porphyry copper deposits; (2) compile a database of known porphyry copper deposits and significant prospects; (3) where data permit, estimate numbers of undiscovered deposits within those permissive tracts; and (4) provide probabilistic estimates the amounts of copper (Cu), molybdenum (Mo), gold (Au), and silver (Ag) that could be contained in those undiscovered deposits.

This paper describes the present politics, economy and problems of Central Asian countries such as Uzbekistan, Kazakhstan, Turkmenistan and others. The presidents of five Central Asian countries are old communists except one country, and these countries are governed undemocratically by state power of presidents. The outline of national security in Central Asia is basically composed of the collective security treaty and each treaty between each country and Russia. Central Asian countries can`t maintain their own armed forces because of financial trouble, depending on Russia. The following can be pointed out as racial problems: overseas Russians lived in old republics of USSR, unstable race structure of Kazakhstan, Tadzhikistan problem, nationalism problem in Uzbekistan, independent movement of minority races, and expansion movement of self-government right. In the old USSR era, the economy of each country depended on the subsidy from Moscow, and such condition continued up to 1993 after their independence, while remarkable reduction of the economy of every country is found since 1994. 75 refs., 12 tabs.

Contemporary Youth Identity in the Republic of Tuva, Russia

2017-09-01

Full Text Available Youth of ethnic Tuvan heritage within the Tuvan Republic (part of the Russian Federation aged 6 to 24 represent a dynamic force which has been shaped by two factors. One is the ancient Turkic heritage of Tuvan culture. Contemporary Tuvans, including youth, display both Russian and Tuvan nationalist feelings, admire martial culture and explore their cultural uniqueness. They hold in high esteem contact sports, especially martial arts such as sambo or judo. Tuvan athletes successfully compete for Russia at international events, including the Olympics. The current Minister of Defense of the Russian Federation is half-Tuvan and extremely popular in the republic, where people see him as nothing short of a national hero. At the same time, young multi-lingual Tuvans, who also speak Russian, and, with access to foreign language education, Korean and English, are being influenced by mediums and through technologies that are international like never before. A special focus is made on the impact of East Asian pop-culture, specifically that of South Korea. Tuva is located in Asia’s geographical center, and is a place where for many centuries Tibetan Buddhism coexisted with Shamanism. Thus, Tuvans strongly identify themselves with Asian culture. They tend to believe in metempsychosis and often tell those who take interest in Tuvan culture that they were Tuvans in their past lives. In their view, Tuvan language has preserved the features of “original” Turkic. These and many other ideas and beliefs show that historical facts and myths are closely intertwined within Tuvan identity. Studying and speaking foreign languages helps prioritize the positive outlook in Tuvan youth, who eagerly study both English and Eastern languages.   In working with Tuvan youth, I was able to teach through games and informal conversation. I was able to meet community leaders who use language to foster lasting change in children’s perception of themselves, as an attempt to

Zika virus (ZIKV) is an emerging mosquito-borne virus that was first isolated from a sentinel rhesus monkey in the Zika Forest in Uganda in 1947. In Asia, the virus was isolated in Malaysia from Aedes aegypti mosquitoes in 1966, and the first human infections were reported in 1977 in Central Java, Indonesia. In this review, all reported cases of ZIKV infection in Asia as of September 1, 2016 are summarized and some of the hypotheses that could currently explain the apparently low incidence of...

High level of molecular and phenotypic biodiversity in Jatropha curcas from Central America compared to Africa, Asia and South America

Science.gov (United States)

2014-01-01

Background The main bottleneck to elevate jatropha (Jatropha curcas L.) from a wild species to a profitable biodiesel crop is the low genetic and phenotypic variation found in different regions of the world, hampering efficient plant breeding for productivity traits. In this study, 182 accessions from Asia (91), Africa (35), South America (9) and Central America (47) were evaluated at genetic and phenotypic level to find genetic variation and important traits for oilseed production. Results Genetic variation was assessed with SSR (Simple Sequence Repeat), TRAP (Target Region Amplification Polymorphism) and AFLP (Amplified fragment length polymorphism) techniques. Phenotypic variation included seed morphological characteristics, seed oil content and fatty acid composition and early growth traits. Jaccard’s similarity and cluster analysis by UPGM (Unweighted Paired Group Method) with arithmetic mean and PCA (Principle Component Analysis) indicated higher variability in Central American accessions compared to Asian, African and South American accessions. Polymorphism Information Content (PIC) values ranged from 0 to 0.65. In the set of Central American accessions. PIC values were higher than in other regions. Accessions from the Central American population contain alleles that were not found in the accessions from other populations. Analysis of Molecular Variance (AMOVA; P jatropha oil significantly differed (P < 0.05) between regions. Conclusions The pool of Central American accessions showed very large genetic variation as assessed by DNA-marker variation compared to accessions from other regions. Central American accessions also showed the highest phenotypic variation and should be considered as the most important source for plant breeding. Some variation in early growth traits was found within a group of accessions from Asia and Africa, while these accessions did not differ in a single DNA-marker, possibly indicating epigenetic variation.

A new order in northeast Asia

Segal, G.

1991-01-01

The fate of northeast Asia is central to the global balance of power. But just as the Cold War took a different course in northeast Asia than it did in its central battleground in Europe, so the post-Cold War world in northeast Asia is taking on a different shape. In Europe, formal arms control was a feature of the political landscape both before and after sweeping changes began altering the face of the continent in 1989. In contrast, northeast Asia saw only informal arms control measures before 1989. But in the post-Cold War world, the opportunity for more formal accords seems to be growing as the changing political environment makes them possible. In the rapidly developing virtuous circle of detente in northeast Asia, the prospects for arms control progress are better than ever, although considerable obstacles remain in the way. One of the unique features of northeast Asia is the convergence of interests of four of the world's most powerful nations - the US, the Soviet Union, Japan, and China. But unlike Europe, where the interests of the Soviet Union and the US have intermingled with those of the diverse members of the European Community (EC) and resulted in far-reaching arms reduction and confidence-building accords, northeast Asia has known only limited regional efforts at reducing tension and enhancing regional security. Nevertheless, unilateral moves and bilateral discussions among the four powers have produced a Sino-Soviet detente, reductions in US and Soviet forces in the Pacific region, the beginning of a Soviet-Japanese dialogue aimed at normalizing relations, and an overall trend toward closer diplomatic and economic relations throughout the region

Alberto Sendra

2017-09-01

Full Text Available A striking new genus and species of Campodeidae (Diplura, Turkmenocampa mirabilis Sendra & Stoev, gen.n., sp.n., found in Kaptarhana cave in Eastern Turkmenistan is described. This represents the first record of Diplura from Central Asia and also the first terrestrial troglobiont found in Turkmenistan. The new taxon shows several unique characters such as the lack of crests on the telotarsus, the presence of a side-shoot process and the shape of barbs on the ventral side of the laminar telotarsal processes hitherto unknown in other members of this family. Although T. mirabilis is tentatively placed in the subfamily Plusiocampinae, its true affinities remain uncertain. The new finding provides further support to the importance of Kaptarhana as a refuge for a number of endemic invertebrates.

China-Russia relations in Central Asia. Energy policy, Beijing's new assertiveness and 21{sup st} century geopolitics

Energy Technology Data Exchange (ETDEWEB)

Eder, Thomas Stephan [Wien Univ. (Austria). Inst. fuer Ostasienwissenschaften

2014-07-01

Publication in the field of social sciences. As China rises to global power status, its relations with other major powers, including Russia, are constantly renegotiated. Energy figures prominently in both countries' foreign policy. An extensive analysis of Chinese language sources - academic debate 1997-2012 - confirms a collision of interests over Central Asian reserves. While unanimous appeals to compromise render previous predictions of impending confrontation unconvincing, descriptions of Sino-Central Asian energy relations as ''central to energy security'', and the explicit rejection of a Russian ''sphere of influence'', also exclude a retreat. In the long term, China will likely replace Russia as the dominant force in Central Asia's energy sector, causing the Kremlin to perceive another ''encroachment''. The current notion of a ''strategic partnership'' will inevitably be challenged.

A Study on International Multimodal Transport Networks from Korea to Central Asia: Focus on Secondhand Vehicles

2016-03-01

Full Text Available Currently, high-income countries use multimodal transportation to export large quantities of secondhand vehicles to low-income countries. Secondhand vehicle export has shown its highest growth in recent years, especially in Korea. The problem of transporting secondhand vehicles from Korea to Central Asia is becoming an important issue, but few researchers are interested in it. The objective of this research is to determine the optimal transport network for exporting secondhand vehicles from Korea to Central Asian countries by combining experts’ opinions and real data from existing transport networks. The fuzzy Delphi method was applied to obtain factors to evaluate alternative multimodal transport networks for moving secondhand vehicles from Korea to Central Asian countries by judgment from experts. The analysis shows that among the five factors (total cost, total time, reliability, security, and transportation capability, total cost is the most considerable factor, followed by reliability, transportation capability, total time, and security. Additionally, in the mainly three multimodal transport networks, the sea+Trans-China Railway route is ranked first, followed by the sea+Trans-Siberian Railway and sea+truck routes.

Historical Influences and a Modern Alternative for Leadership Models in Central Asia = Orta Asya'da Liderlik Modellerinde Tarihsel Etkiler ve Modern Alternatifler

Directory of Open Access Journals (Sweden)

Sean Michael COX

2002-06-01

Full Text Available The 1991 demise of the Soviet Union that led to the emancipation of many Central Asian states, also led to a grab for power by a variety of leadership types. Although the characteristics of leadership types in the 1990s were diverse, few followed the pattern of Samuel Huntington's Third Wave of authoritarian transition, whereby authoritarian regimes were abandoned in favor of democratically elected and democratically oriented governments. Historically, Eurasia has had little experience with popular government. This is reflected in the general characteristics of leadership types in the post-Soviet era, which closely follow three regional historical influences - the early Islamic Emperors, the Mongolian Khans and the Russian Tsars (and later Soviet leaders. This article examines the historic influences on Eurasian leadership types and the impact of these types on the politics, societies and economies of these same states. It will be argued that at the current stage of political development, it would ultimately benefit the states of Central Asia to follow, at this time, the most successful Eurasian model to date, that of Kemal Atatürk and Turkey, rather than to push for a fully participatory democracy or sustain the post-Soviet personal dictatorships that have prospered throughout Central Asia.

Tracing the origin of the east-west population admixture in the Altai region (Central Asia.

Mercedes González-Ruiz

Full Text Available A recent discovery of Iron Age burials (Pazyryk culture in the Altai Mountains of Mongolia may shed light on the mode and tempo of the generation of the current genetic east-west population admixture in Central Asia. Studies on ancient mitochondrial DNA of this region suggest that the Altai Mountains played the role of a geographical barrier between West and East Eurasian lineages until the beginning of the Iron Age. After the 7th century BC, coinciding with Scythian expansion across the Eurasian steppes, a gradual influx of East Eurasian sequences in Western steppes is detected. However, the underlying events behind the genetic admixture in Altai during the Iron Age are still unresolved: 1 whether it was a result of migratory events (eastward firstly, westward secondly, or 2 whether it was a result of a local demographic expansion in a 'contact zone' between European and East Asian people. In the present work, we analyzed the mitochondrial DNA lineages in human remains from Bronze and Iron Age burials of Mongolian Altai. Here we present support to the hypothesis that the gene pool of Iron Age inhabitants of Mongolian Altai was similar to that of western Iron Age Altaians (Russia and Kazakhstan. Thus, this people not only shared the same culture (Pazyryk, but also shared the same genetic east-west population admixture. In turn, Pazyryks appear to have a similar gene pool that current Altaians. Our results further show that Iron Age Altaians displayed mitochondrial lineages already present around Altai region before the Iron Age. This would provide support for a demographic expansion of local people of Altai instead of westward or eastward migratory events, as the demographic event behind the high population genetic admixture and diversity in Central Asia.

In Central Asia (CA) the radioactive waste comes mainly from uranium mining and milling, nuclear weapon testing and nuclear power development and other ionizing sources. This waste was produced, to a greater extent, by the military-industrial complex and the uranium and non-uranium industry, and, to a lesser extent, by the nuclear industry and in the process of use of isotope products. Exploitation and mining of uranium and thorium deposits produce a large amount of solid and liquid radioactive waste, as well volatile contaminants which need a proper management. In Central Asia the wastes are mainly stored at the surface in large piles and represent a long-term potential health and environmental hazard. The process of remediating legacy sites of the past and reducing the threats is now getting under way, with the design and implementation of remediation activities, partly with international support. However, there is a significant lack in the regulatory basis for carrying out such remediation work, including a lack of relevant radiation and environmental safety norms and standards, licensing procedures and requirements for monitoring etc., as well as expertise to transform such a basis into practice. Accordingly, the objective of the proposed project is to assist the relevant regulatory authorities in Kazakhstan, Kirgizstan and Tajikistan to develop national robust and adequate regulations and procedures, taking into account the international guidance and Norwegian experience with regulatory support projects in Russia. Specific expected results in the project period include: a threat assessment report identifying priority areas for regulatory development, based on the status of current regulatory documents and the hazard presented by the different sites and facilities; development of national radioactive waste management strategies in each country; development of an enhanced regulatory framework for supervision of nuclear matters, and an enhanced safety culture

2005-04-15

This research deals with a number of issues on the transformation process, sustainable development and regional cooperation in Central Asia. These areas of the research are discussed within the three models of development, i.e. national, regional, and global. Within the new concept on stability and conflict prevention, the author attempted to sort out the economic fundamentals affecting contemporary development of the states in the region. The main focus is made on Uzbekistan which is the most populated country in the region and whose socio-political and economic development has substantial impact on the regional situation. The analysis of the country's progress in domestic economic reforms in the past not only defines some conflict areas of development, but also tries to shape those fields where national strategy is confronted with difficulties on the long and pain-staking way from the plan system towards liberal market economy and democratic society. At the sector-specific level, particular attention is paid to the trends in Uzbekistan's energy sector. Simultaneously the work argues that national policy decisions in the energy field go much beyond national borders, and strongly correlated to intra-regional relations, as well as to those heated by geopolitical and geoeconomic considerations of the USA, Russia, Iran, China, the EU, and Turkey. Subsequently, the research concludes that Central Asia so far remains mainly as an object of expansion of great geopolitical interests rather than being a sovereign player in international relations. In this regard, sustainable development of the states in the region is expected to depend to a large extent on how the interests of the regional states will be put in line with those of non-regionals. Finally, the research emphasizes that in terms of limited domestic resources, investment and donor activities are desperately needed, both in Uzbekistan and the whole region, to modernize production process, raise efficiency, create

The vast arid and semi-arid regions of central Asia, Mongolia, and Northern China are the world's second largest source of atmospheric mineral dust. In recent years, severe dust storms in Asia have intensified in frequency, duration, and areal coverage. However, limited spatial and temporal extent of aerosol measurements precludes definitive statements to be made regarding relationship between the Asian aerosol generation and climate. It has been well known that glaciers are the natural archives of environmental records related to past climate and aerosol generation. In our research, we utilized central Asian and western Siberia shallow ice-core records recovered from Altai, Tien Shan and Pamir mountain glaciers. Despite the fact that ice-core data may extend climate/aerosol records back in time, their sparse coverage is inadequate to document aerosol spatial distribution. The NASA products from Aura, Terra and Aqua satellite missions address this gap identifying aerosol sources, transport pathways, and area of deposition. The main objective of our research is to evaluate an affect of climate variability on dynamics of Asian aerosol loading to atmosphere and changes in aerosol transport pathways. Dust particle, major and rare earth element analysis from dust aerosols deposited and accumulated in Altai, Tien Shan and Pamir glaciers suggests that loess from Tajikistan, Afghanistan and north-western China are main sources of aerosol loading into the upper troposphere over the central Asia and western Siberia. At the same time, the soluble ionic component of the ice-cores, related to aerosol generated from evaporate deposits, demonstrated both anthropogenic and natural impacts on atmospheric chemistry over these regions. Large perturbations of Ca2+ derived from CaCO3- rich dust transported from Goby Desert to Altai and Tien Shan. Origin and pathway of the ice-core aerosol depositions for the last 10-years were identified through calibrating ice-core records with dust

To evaluate glaucoma prevalence and disease burden across Asian subregions from 2013 to 2040. We conducted a systematic review and meta-analysis of 23 population-based studies of 1318 primary open angle glaucoma (POAG) cases in 66,800 individuals and 691 primary angle closure glaucoma (PACG) cases in 72,767 individuals in Asia. Regions in Asia were defined based on United Nations' (UN) classification of macro-geographic regions. PubMed, Medline and Web of Science databases were searched for population-based glaucoma prevalence studies using standardised criteria published to 31 December 2013. Pooled glaucoma prevalence for individuals aged 40-80 years was calculated using hierarchical Bayesian approaches. Prevalence differences by geographic subregion, subtype and habitation were examined with random effects meta-regression models. Estimates of individuals with glaucoma from 2013 to 2040 were based on the UN World Population Prospects. In 2013, pooled overall glaucoma prevalence was 3.54% (95% credible interval (CrI) 1.83 to 6.28). POAG (2.34%, 95% CrI 0.96 to 4.55) predominated over PACG (0.73%, 95% CrI 0.18 to 1.96). With age and gender adjustment, PACG prevalence was higher in East than South East Asia (OR 5.55, 95% CrI 1.52 to 14.73), and POAG prevalence was higher in urban than rural populations (OR 2.11, 95% CrI 1.57 to 2.38). From 2013 to 2040, South Central Asia will record the steepest increase in number of glaucoma individuals from 17.06 million to 32.90 million compared with other Asian subregions. In 2040, South-Central Asia is also projected to overtake East Asia for highest overall glaucoma and POAG burden, while PACG burden remains highest in East Asia. Across the Asian subregions, there was greater glaucoma burden in South-Central and East Asia. Sustainable public health strategies to combat glaucoma in Asia are needed.

In this study, structural analysis, 40Ar-39Ar dating, and paleomagnetic studies were performed to investigate the kinematics of the XMF and to further discuss its Triassic geodynamic significance in the Central-Eastern Asia framework after the Paleozoic Central Asian Orogenic evolution. The structural analyses reveal two phases of ductile deformation. The first one (D1), which displays N-verging and E-W trending folds, is related to the Early Paleozoic collisional event between the NCB and the Songliao-Hunshandake Block (SHB). The second phase (D2) displays a high-angle foliation and a pervasive sub-horizontalE-W stretching lineation with kinematic criteria indicative of dextral strike-slip shearing. The 40Ar-39Ar dating on mylonitic granite places the main shearing event around 227-209 Ma. This D2 shearing is coeval with that of the dextral strike-slip Bayan Obo-Chifeng Fault (BCF) and the Chicheng-Fengning-Longhua Fault to the south, which together constitute a dextral shearing fault system on the northern margin of the NCB during the Late Triassic. The paleomagnetic study performed on the Middle Permian Guangxingyuan pluton, located between the XMF and BCF, documents a local clockwise rotation of this pluton with respect to the NCB and SHB. Our multidisciplinary study suggests anNNW-SSE shortening and strike-slip shearing dominated tectonic setting on the northern margin of the NCB during the Late Triassic. Combining the contemporaneous dextral strike-slip movements of the XMF and BCF in northern China and the sinistral strike-slip movement of East Gobi Fault (EGF) in southeastern Mongolia with the large-scale tectonic framework, a Late Triassic NNW-SSE shortening-eastward extrusion

the world. Tuva now has its rock, as well as avant-garde, women bands, etc. Throat-singing became a popular type of vocal arts. Tuvan music attracts hundreds of thousands of fans around the world. Circulation of media, especially with Tuvan music, allowed musicians of Sayan-Altai region and Central Asia to rediscover many of their own genres. Thus, Tuvan music burst into the world like a Mongol invasion in early 1990s. Global success of Tuvan music on the world music market is obvious. But the process of normalization of Tuvan music perception by the outer world is inevitable.  This article has audio files attached (please, see "Supplementary files" in "Article tools".

Demyelinating diseases in Asia.

The present review aims to discuss the recent advances in inflammatory demyelinating diseases of the central nervous system in Asia. Prevalence of multiple sclerosis (MS) in Asia is lower than that in Western countries, although it has been increasing recently. Meanwhile, there seems to be no major difference in neuromyelitis optica (NMO) prevalence in various regions or ethnicities. Thus, the ratios of NMO/NMO spectrum disorder (NMOSD) to MS are higher in Asia as compared with Western countries, indicating that the differential diagnosis between NMO/NMOSD and MS is a major challenge in Asia. Although the detection of aquaporin-4 (AQP4)-antibody is critical in distinguishing NMO/NMOSD from MS, some patients with NMO/NMOSD phenotype are seronegative for AQP4-antibody, and a fraction of those patients possess autoantibody against myelin oligodendrocyte glycoprotein. The clinical profile of Asian MS seems to be essentially similar to that in Western MS after careful exclusion of NMO/NMOSD, although some unique genetic and/or environmental factors may modify the disease in Asians. MS prevalence has been low but is increasing in Asia. In contrast, NMO/NMOSD prevalence seems relatively constant in the world. Asian MS is not fundamentally different from Western MS, but some genetic and/or environmental differences may cause some features unique to Asian patients.

Water is a key agent in Central Asia ultimately determining human well-being, food security, and economic development. There are complex interplays among the natural and anthropogenic drivers effecting the regional hydrological processes and water availability. Analysis of the data combined from regional censuses and remote sensing shows a decline in areas of arable and irrigated lands and a significant decrease in availability of arable and irrigated lands per capita across all Central Asian countries since the middle of 1990thas the result of post-Soviet transformation processes. This change could lead to considerable deterioration in food security and human system sustainability. The change of political situation in the region has also resulted in the escalated problems of water demand between countries in international river basins. We applied the University of New Hampshire - Water Balance Model - Transport from Anthropogenic and Natural Systems (WBM-TrANS) to understand the consequences of changes in climate, water and land use on regional hydrological processes and water availability. The model accounts for sub-pixel land cover types, glacier and snow-pack accumulation/melt across sub-pixel elevation bands, anthropogenic water use (e.g. domestic and industrial consumption, and irrigation for most of existing crop types), hydro-infrastructure for inter-basin water transfer and reservoir/dam regulations. A suite of historical climate re-analysis and temporal extrapolation of MIRCA-2000 crop structure datasets has been used in WBM-TrANS for this project. A preliminary analysis of the model simulations over the last 30 years has shown significant spatial and temporal changes in hydrology and water availability for crops and human across the region due to climatic and anthropogenic causes. We found that regional water availability is mostly impacted by changes in extents and efficiency of crop filed irrigation, especially in highly arid areas of Central Asia

This evolution, especially with regard to the deficiencies in democracy and legitimacy of the majority of the current governments, based, in many cases, on personalist, authoritarian regimes, points to an uncertain future for a region in which, too frequently, its rulers have used all the means at their disposal (persecution of political opposition, disregard for human rights, constraint of the mass media and NGOs, etc. to guarantee their continuance in power.

This article examines impacts of infrastructure development and climate variability on economic outcomes for the Amu Darya Basin in Central Asia. It aims to identify the most economically productive mix of expanded reservoir storage for economic benefit sharing to occur, in which economic welfare of all riparians is improved. Policies examined include four combinations of storage infrastructure for each of two climate futures. An empirical optimization model is developed and applied to identify opportunities for improving the welfare of Tajikistan, Uzbekistan, Afghanistan, and Turkmenistan. The analysis 1) characterizes politically constrained and economically optimized water-use patterns for these combinations of expanded reservoir storage capacity, 2) describes Pareto-Improving packages of expanded storage capacity that could raise economic welfare for all four riparians, and accounts for impacts for each of two climate scenarios. Results indicate that a combination of targeted water storage infrastructure and efficient water allocation could produce outcomes for which the discounted net present value of benefits are favorable for each riparian. Results identify a framework to provide economic motivation for all riparians to cooperate through development of water storage infrastructure. Our findings illustrate the principle that development of water infrastructure can expand the negotiation space by which all communities can gain economic benefits in the face of limited water supply. Still, despite our optimistic findings, patient and deliberate negotiation will be required to transform potential improvements into actual gains.

Recent biomass burning in Southeast Asia has raised global concerns over its adverse effects on visibility, human health, and global climate. The concentrations of total suspended particles (TSPs) and other vapor-phase pollutants (CO and ozone) were monitored at Lulin, an atmospheric background station in central Taiwan in 2008. To evaluate the long-range transport of persistent organic pollutants (POPs) during the Southeast Asia biomass burning event, the atmospheric polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were also measured at Lulin station. The atmospheric PCDD/F and TSP concentrations measured at Lulin station ranged from 0.71-3.41 fg I-TEQ/m(3) and 5.32-55.6 microg/m(3), respectively, during the regular sampling periods. However, significantly higher concentrations of PCDD/Fs, TSPs, CO, and ozone were measured during the spring season. These high concentrations could be the result of long-range transport of the products of Southeast Asia biomass burning. During the Southeast Asia biomass burning event (March 18-24, 2008), an intensive observation program was also carried out at the same station. The results of this observation program indicated that the atmospheric PCDD/F concentration increased dramatically from 2.33 to 390 fg I-TEQ/m(3) (March 19, 2008). The trace gas (CO) of biomass burning also significantly increased to 232 ppb during the same period, while the particle-bound PCDD/Fs in the TSP increased from 28.7 to 109 pg I-TEQ/g-TSP at Lulin station during the burning event. We conclude that there was a significant increase in the PCDD/F concentration in ambient air at a high-altitude background station in central Taiwan during the Southeast Asia biomass burning event.

The position of the Pamirs and the Hissar-Alai mountainous system in the structure of Central Asia and features of their junction are considered. It is shown that their outer contours and tectonic infrastructure are significantly distinct in the planar pattern: latitudinally linear and arched for the Hissar-Alai and the Pamirs, respectively. These structures logically match those of the Central Asian and Alpine-Himalayan belts, respectively. The Pamir orogen is a relatively autonomous structural element of the crust, which is located discordantly relative to the country lithospheric blocks. Most of the Pamirs (at least, the Northern and Central) probably form a giant allochthon on the ancient basement of the Tarim and Afghan-Tajik blocks. The junction zone of these two "hard" crustal segments is reflected in the transverse Transpamir threshold, which is expressed in the relief, deep structure, and seismicity. The specific geological structure of the junction zone of the Pamirs and Hissar-Alai (systems of the Tarim, Alai, and Afghan-Tajik troughs) is shown. It suggested that this zone is a damper, which significantly neutralizes the dynamic influence of the Pamir and the southernmost elements of the Pamir-Punjab syntax on Hissar-Alai structures.

Accurate and update assignment of population-related environmental matters onto fine grid cells in oasis cities of arid areas remains challenging. We present the approach based on Suomi National Polar-orbiting Partnership (S-NPP) -Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) to reallocate population onto a regular finer surface. The number of potential population to the mercury were reallocated onto 0.1x0.1 km reference grid in Urumqi city cluster of China’s Xinjiang, central Asia. The result of Monte Carlo modelling indicated that the range of 0.5 to 2.4 million people was reliable. The study highlights that the NPP-VIIRS DNB-based multi-layered, dasymetric, spatial method enhances our abilities to remotely estimate the distribution and size of target population at the street-level scale and has the potential to transform control strategies for epidemiology, public policy and other socioeconomic fields.

The seasonal, interannual, and long-term variations in biomass burning activity and related emissions are not well studied over South Asia. In this regard, active fire location retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS), the retrievals of aerosol optical depth (AOD) from MODIS Terra, and tropospheric column NO2 from Ozone Monitoring Instrument (OMI) are used to understand the effects of biomass burning on the tropospheric pollution loadings over South Asia during 2003-2013. Biomass burning emission estimates from Global Fire Emission Database (GFED) and Global Fire Assimilation System (GFAS) are also used to quantify uncertainties and regional discrepancies in the emissions of carbon monoxide (CO), nitrogen oxide (NOx), and black carbon (BC) due to biomass burning in South Asia. In the Asian continent, the frequency of fire activity is highest over Southeast Asia, followed by South Asia and East Asia. The biomass burning activity in South Asia shows a distinct seasonal cycle that peaks during February-May with some differences among four (north, central, northeast, and south) regions in India. The annual biomass burning activity in north, central, and south regions shows an increasing tendency, particularly after 2008, while a decrease is seen in northeast region during 2003-2013. The increase in fire counts over the north and central regions contributes 24 % of the net enhancement in fire counts over South Asia. MODIS AOD and OMI tropospheric column NO2 retrievals are classified into high and low fire activity periods and show that biomass burning leads to significant enhancement in tropospheric pollution loading over both the cropland and forest regions. The enhancement is much higher (110-176 %) over the forest region compared to the cropland (34-62 %) region. Further efforts are required to understand the implications of biomass burning on the regional air quality and climate of South Asia.

Long-range transport of air pollution from continental Asia is currently an important issue concerning the Japanese environment, especially in regions susceptible to acidification due to low buffering capacity, such as Murakami, Niigata prefecture, located on the west coast of central Japan. Evidence for long-range transport was obtained through lead and lead isotopic analysis of 84 archived precipitation filters, showing seasonal changes in lead deposition from May 1999 to May 2002. Lead deposition was highest in winter and spring (November through May) each year and lowest in summer. Computed 72-h back trajectories showed that in winter air masses were predominantly transported from the northwest, passing over northern China and eastern Russia, whilst in summer air masses predominantly originated from the southeast passing over Japan. Lead isotopic analysis showed higher 208 Pb/ 206 Pb during winter, indicating that lead originated from a different source. A plot of 207 Pb/ 206 Pb vs. 208 Pb/ 206 Pb identified a thorogenic component, which is excess 208 Pb compared to a standard lead growth curve, indicative of certain lead ores and coals in continental Asia. The data provided evidence of long-range transport of lead from continental Asia to Japan. Bark pockets included within the trunks of two Japanese cedar trees harvested near Murakami, dating between 1972 and 1982, exhibited lead isotope ratios indicative of Japanese-sourced lead. In contrast, current (2003) bark showed thorogenic ratios, consistent with a relative decline in Japanese-sourced and increase in continental-sourced lead

To evaluate etanercept in patients from Latin America, Central/Eastern Europe, and Asia with non-radiographic axial spondyloarthritis (nr-axSpA). A subset analysis was performed on nr-axSpA patients from Argentina, Colombia, the Czech Republic, Hungary, Russia and Taiwan who were enrolled in EMBARK (NCT01258738). Patients received either etanercept 50 mg or placebo once weekly. The primary endpoint was proportion of patients achieving 40% improvement from baseline based on Assessment of SpondyloArthritis International Society (ASAS) criteria. Secondary endpoints included other efficacy assessments, health-related quality of life (HRQoL) and safety. Of the 117 patients in this subset, 59 were treated with etanercept and 58 received placebo. At week 12, numerically greater improvements from baseline were observed for all efficacy endpoints in etanercept-treated patients compared with those receiving placebo. Statistically significant differences between the two treatment groups were observed for proportion of patients achieving ASAS40 (P = 0.0413, at week 8), ASAS5/6 (P = 0.0126), Ankylosing Spondylitis Disease Activity Score - C-reactive protein (CRP) inactive disease (P = 0.0093), Spondyloarthritis Research Consortium of Canada magnetic resonance imaging of sacroiliac joint scores (P = 0.0014), high-sensitivity CRP (P=0.032), and erythrocyte sedimentation rate (P = 0.0082). Statistically significant improvements in the etanercept-treated group compared with placebo group were observed for nocturnal back pain (P = 0.040), total back pain (P = 0.025), physician global assessment of disease (P = 0.023), and Work Productivity and Activity Impairment Questionnaire percent impairment while working (P = 0.047). Adverse events were similar between the two treatment groups. In this subset of patients with nr-axSpA from Latin America, Central/Eastern Europe, and Asia, treatment with etanercept, compared with placebo, resulted in improved disease symptoms and patient HRQo

Last Glacial Maximum (LGM) carbon storage in eastern Asia is a key issue for understanding the sinks and sources of paleocarbon. Palynological data with good time constraint for the LGM in a peat bog from a site at 650 m above mean sea level in central Taiwan, together with data from low-lying deltaic and basin deposits of Taiwan and South China, increase our understanding about vegetational evolution and possible terrestrial carbon storage in this area and probably eastern Asia. Contrasting to today`s Machilus-Castanopsis forest zone around the peat bog, the vegetation before the LGM was dominated by Alnus, a relatively xerophytic element in Taiwan. An increase in herbs and decrease in spores during the LGM is recognized when compared with Holocene and modern assemblages. A less humid interval dominated by herbs (>50%) occurred between 21 and 15.8 ka. Basin deposits in northern Taiwan and deltaic deposits in central Taiwan show that during the LGM Artemisia, Umbelliferae and Gramineae were the main components contrasting with the Pinus or Cyclobalanopsis-dominant assemblages in the rest of the last glacial. Thus, less humid conditions lasted about 5000 to 6000 years in the LGM even on this very humid island. This may also be true in eastern Asia where a large area of the widely exposed continental shelf may have been occupied by grasslands and the uplands of South China were occupied by less dense coniferous or temperate forests during the LGM in contrast to the modern subtropical forest. This scenario improves our understanding of the terrestrial paleocarbon storage

Conservation Agriculture for combating land degradation in Central Asia: a synthesis

Directory of Open Access Journals (Sweden)

J.P.A. Lamers

2016-04-01

Full Text Available This manuscript reviews scientific findings on agricultural systems, associated land degradation and selected remedies such as Conservation Agricultural (CA practices to counterbalance these. In particular, this review addresses the research findings onCA practices conducted in the rainfed and irrigated systems in Central Asia. The arid and semi-arid croplands in this region are vulnerable to different types of soil and environmental degradation, and particularly to degradation caused by intensive tillage, irrigation water mismanagement, and cropping practices, especially in the Aral Sea Basin. Overall, the evidence shows that various CA elements, such as permanent beds, seems to be technically suitable for the major cropping systems and despite the heterogeneous conditions in the region. CA practices can contribute to combating on-going land degradation. No-till seeding along with the maintenance of a permanent soil coverage e.g. by residue retention, reduces wind and water erosion, increases water infiltration and storage which can reduce crop water stress, improve soil quality and increase soil organic matter. Further, CA practices can lead to similar or even higher crop yields while reducing production resource needs and costs considerably, including fuel, seeds, agrochemicals, water and labour. Nevertheless, the growing research evidence on the productivity, economic and environmental benefits that can be harnessed with CA, still is from a limited number of studies and hence more research at local scale is needed.

Both climate change and anthropogenic activities contribute to deterioration of terrestrial water resources and ecosystems worldwide. It has been observed in recent decades that water-limited steppe regions of Central Asia are among ecosystems found to exhibit enhanced responses to climate variability. In fact, the largest share of worldwide net loss of permanent water extent is geographically concentrated in the Central Asia and Middle East regions attributed to both climate variability/change and human activities impacts. We used a digital elevation model, digitized bathymetry maps and high resolution Landsat images to estimate the areal water cover extent and volumetric storage changes in small terminal lakes in Burabay National Nature Park (BNNP), located in Northern Central Asia, for the period 2000-2016. Based on the analysis of long-term climatic data from meteorological stations, hydrometeorological network observations as well as regional climate model projections we evaluate the impacts of past thirty years and future climatic conditions on the water balance of BNNP lake catchments. The anthropogenic water consumption was estimated based on data collected at a local water supply company and regulation authorities. One the one hand historical in-situ observations and future climate projections do not show a significant change in precipitation in BNNP. On the other hand both observations and the model demonstrate steadily rising air temperatures in the area. It is concluded that the long-term decline in water levels for most of these lakes can be largely attributed to climate change (but only via changes in air temperature, causing evaporation to exceed precipitation) and not to direct anthropogenic influences such as increased water withdrawals. In addition, the two largest lakes, showing the highest historical water level decline, do not have sufficient water drainage basin area to sustain water levels under increased evaporation rates.

Sustainable waste management and disposal is a societal challenge in terms of economics, public health and environmental impact. The situation in developing countries, and in particular those subject to extreme natural hazards, results in increased overall risk as governments prioritize investments to issues of perceived higher economic importance. This dissertation investigates environmental risks associated with landfills in seismically active regions in the New Independent States of Central Asia. Environmental risk from municipal solid waste landfill sites encompasses a wide range of topics within socio-economics, physical sciences and engineering and therefore necessitates a multi-disciplinary approach. The underlying study is an accumulative result of a three-year collaborative research project (Contract No. INCO-CT-2005-516732) funded within the Eu Sixth Framework Programme (FP6). The international cooperation involved European, Russian and Central Asian research partners forming a multi-disciplinary consortium covering: GIS technologies, geology / hydrogeology geophysics and geotechnical engineering; landfill design and operation and waste management. understanding the relevant socio-economic aspects and legislative frameworks was necessary to prepare results and recommendations to address stakeholders in the Central Asian countries: Kazakhstan, Kyrgyzstan,Tajikistan,Turkmenistan and uzbekistan.

Connections between Central Asia and Mediaeval Croatia

Emil Heršak

1999-06-01

Full Text Available The paper analyses the development of Croat visions of self-origin, especially in relation to the Central Asian or Central Eurasian world. Located on the southern rim of the Pannonia plain, which constitutes a type of continuity of the great Eurasian steppe, the area of Croatia has many times in the past been exposed to diverse incursions of nomadic peoples from the East. True, the oldest expansions from the East in the context of initial Indo-Europeanisation (i.e. effects on the aeneolithic Vučedol culture, etc. cannot yet be included in such a scheme. The “Scythian-Cimmerian phenomenon” in the early Iron Age marks the first appearance of this model in regard to the Croatian area. Towards the end of historical Antiquity, Yazygs and other Sarmatians arrived from the East, and later the movement of the Huns created the stereotype through which contemporaries envisioned the following incursions of Bulgars and Avars, closed connected to the Slavic migrations, the arrival of the Hungarians and later the Tatar-Mongol invasion. Although essentially different, the subsequent Ottoman Turk expansion – which was to have significant ramifications for Croatia – also constituted an aspect of the total picture of relations with Asia. At the beginning of the Ottoman invasion, the old phrase dating from the Mediaeval Crusades, antemurale Christianitatis, was applied to Croatia. This had double significance. On the one hand it confirmed ties with the Western Christendom, but on the other hand the very term antemurale (“forewall, bulwark” implies an external position, hence a certain conceptual shift of Croatia toward the Orient. In the next part of the paper, the authors examine various legends pertaining to Croat origins. The oldest were registered by the Byzantine emperor Constantine VI Porphyrogenitus. This included the account of the invitation made by the emperor Heraclius to the Croats and the story of the arrival of the Croats under the

Postoperative central nervous system infections (PCNSIs) are rare but serious complications after neurosurgery. The purpose of this study was to examine the prevalence and causative pathogens of PCNSIs at a modernized, resource-limited neurosurgical center in South Asia. A retrospective analysis was conducted of the medical records of all 363 neurosurgical cases performed between June 1, 2012, and June 30, 2013, at a neurosurgical center in South Asia. Data from all operative neurosurgical cases during the 13-month period were included. Cerebrospinal fluid (CSF) analysis indicated that 71 of the 363 surgical cases had low CSF glucose or CSF leukocytosis. These 71 cases were categorized as PCNSIs. The PCNSIs with positive CSF cultures (9.86%) all had gram-negative bacteria with Pseudomonas aeruginosa (n = 5), Escherichia coli (n = 1), or Klebsiella pneumoniae (n = 1). The data suggest a higher rate of death (P = 0.031), a higher rate of CSF leak (P < 0.001), and a higher rate of cranial procedures (P < 0.001) among the infected patients and a higher rate of CSF leak among the patients with culture-positive infections (P = 0.038). This study summarizes the prevalence, causative organism of PCNSI, and antibiotic usage for all of the neurosurgical cases over a 13-month period in a modernized yet resource-limited neurosurgical center located in South Asia. The results from this study highlight the PCNSI landscape in an area of the world that is often underreported in the neurosurgical literature because of the paucity of clinical neurosurgical research undertaken there. This study shows an increasing prevalence of gram-negative organisms in CSF cultures from PCNSIs, which supports a trend in the recent literature of increasing gram-negative bacillary meningitis.

The earth is warming, and it is warming quickly. Epidemiological studies have demonstrated that global warming is correlated with the frequency of pollen-induced respiratory allergy and allergic diseases. There is a body of evidence suggesting that the prevalence of allergic diseases induced by pollens is increasing in developed countries, a trend that is also evident in the Mediterranean area. Because of its mild winters and sunny days with dry summers, the Mediterranean area is different from the areas of central and northern Europe. Classical examples of allergenic pollen-producing plants of the Mediterranean climate include Parietaria, Olea and Cupressaceae. Asia Minor is a Mediterranean region that connects Asia and Europe, and it includes considerable coastal areas. Gramineae pollens are the major cause of seasonal allergic rhinitis in Asia Minor, affecting 1.3-6.4 % of the population, in accordance with other European regions. This article emphasizes the importance of global climate change and anticipated increases in the prevalence and severity of allergic disease in Asia Minor, mediated through worsening air pollution and altered local and regional pollen production, from an otolaryngologic perspective.

Creation of zone free nuclear weapon (ZFNW) in the Central Asia

Issues on non-proliferation of mass demolition weapons are of special importance for people of Kazakhstan. The whole damage brought to nature and people's health by nuclear tests at the Semipalatinsk test site (STS) is not revealed yet. Kazakhstan contributed much to the matter of nuclear disarmament. More than six years ago for the first time in the world by RK President's resolution an operating nuclear test site closed. Kazakhstan was the first to fulfill obligations in accordance with Lisbon protocol. Kazakhstan liquidated the fourth nuclear potential in the world. It's time to undertake further steps in the field of non-proliferation. One of such steps is the creation of a ZFNW in the central Asia. The idea of ZFNW creation is being acknowledged more and more during last 30 years. All the four present zones include more than 100 countries. If the Antarctic Region is taken into account the zones cover more than 50% of dry land. Regional ZFNWs attract attention as a means of reflecting and rewarding general valuers in the sphere of nuclear disarmament and armament control. Such zones help tj narrow geographical sphere of military nuclear activity and to strengthen non-proliferation regime. The importance of ZFNW in the process of strengthening global and regional peace and safety is confirmed by the documents of Conference for countries joined the agreement on non-proliferation (AN) of 1995 and the first meeting of the Organizing Committee for Conference of 2000

Bridging Glaciological and Hydrological Trends in the Pamir Mountains, Central Asia

Malte Knoche

2017-06-01

Full Text Available With respect to meteorological changes and glacier evolution, the southern Pamir Mountains are a transition zone between the Pamirs, Hindu Kush and Karakoram, which are water towers of Central Asia. In this study, we compare runoff and climate trends in multiple time periods with glacial changes reported in the literature. Recent glacier evolution in the Southern Pamirs and its contribution to river runoff are studied in detail. Uncertainties of estimating glacier retreat contribution to runoff are addressed. Runoff trends in the Pamir-Hindu Kush-Karakoram region appear to be a strong proxy for glacier evolution because they exhibit the same spatial pattern as glacial change. There is an anomaly in the North-West Pamirs and Northern Karakoram, showing decreasing runoff trends. In the opposite way, there is a glacier and hydrological change experienced in the Southern Pamirs and Hindu Kush. The prevailing hypothesis for the Karakoram Anomaly, decreasing summer temperatures along with increasing precipitation rates, seems to be valid for the North-Western Pamirs, as well. In the Southern Pamirs, temperature trends have been rising since 1950. Here, the unique water cycle of exclusively winter precipitation does not protect glaciers from accelerated retreat. Snow cover is preset to melt within the seasonal water cycle, due to much lower precipitation amounts falling on glaciers. Therefore, a probable increase in westerly precipitation in both regions causes glacier mass gain in the Northern Pamirs and rising river flows in the Southern Pamirs.

Teaching Central Eurasia in Undergraduate Survey Courses: Problems and Strategies

Amy Kardos

2014-06-01

Full Text Available Recent scholarship has challenged narratives of Central Eurasia’s relationships with its neighbors in East Asia, South Asia, and Southwest Asia.  This scholarship explains the trade networks that are commonly called the “Silk Routes” as the foreign trade component of a complex and dynamic Central Eurasian economy.  Scholarship of Central Eurasia also challenges long-standing narratives of “needy” or “predatory” nomads that militarily overwhelm sedentary empires. This article discusses the importance of incorporating such ideas into world history and Asian history survey courses, which are often taught by non-specialists who have only encountered Central Eurasia in their respective fields as a periphery.  Correcting misconceptions about Central Eurasia’s relationship with its neighbors also provides opportunities for students to think critically about historical sources and move past stereotypes of “barbarian” and “civilization.”

Uranium resources potential for Asia and the Pacific

Tauchid, M.

Only four countries in Asia, India, Japan, the Republic of Korea and Turkey, reported having uranium resources in response to a Nuclear Energy Agency of the OECD/International Atomic Energy Agency questionnaire circulated before preparation of the report on Uranium: Resources, Production and Demand (the 'Red Book'). The reasonably assured resources (RAR) of these countries, which are recoverable at costs of up to US $130/kg U, amount to 67,690 t U or 3% of the total for the World Outside the Centrally Planned Economies Area (WOCA). It is believed that the largest uranium resources in Asia are in China; however, no official published figures are available to substantiate this fact. Within the framework of the International Uranium Resources Evaluation Project (IUREP) it was estimated that the speculative resources (SR) for Asia and the Far East outside the Centrally Planned Economies Area (CPEA) are of the order of 300,000 t U. This is 4.7% of the total for WOCA. With the exception of Proterozoic unconformity related deposits, all types of uranium deposits and occurrences are known to exist in Asia. Most deposits are of the vein and sandstone hosted types. Several published reports indicate that deposits in China are mainly of the volcanic type and those associated with granitic intrusion. For undiscovered deposits, probably India and China have the best possibility of finding deposits of the Precambrian quartz-pebble conglomerate and Proterozoic unconformity related types. In South-East Asia the deposits most likely to be found are those associated with Mesozoic granites and those in the intramontane basin sediments adjacent to these intrusions. The less known acid volcanic type is also a possibility. Only in China, India and Pakistan does there appear to be the possibility of finding calcrete type deposits. Uranium can still be recovered as a by-product of the phosphate rocks, monazite placer deposits and carbonatite known in many parts of Asia. (author). 21 refs

Full Text Available Penile fracture is a well-recognized, relatively uncommon medical condition and its etiology differs according to geographic area. In this review article, we evaluated literature reported in the past decade, aiming to verify whether there has been any change in the etiology of this condition. A literature review was done for studies published in the past 10 years and focusing on the etiology of penile fracture. Inclusion criteria comprised articles in English language, of sample size more than 10 patients and originating from the Middle East and Central Asia. Data relating to the studied population, etiology of penile fracture, clinical presentation, investigations, management, and outcome was analyzed. One thousand six hundred and twenty-nine patients from 21 original articles were included in the study. The mean age ΁ standard deviation of the patients was 33.3 ΁ 3.23 years. Etiologies of penile fracture were vigorous sexual intercourse, manual bending of erect penis, vigorous masturbation, rolling over in bed and blunt trauma in 41%, 29%, 10%, 14% and 6% patients, respectively. Treatment choices were surgery and conservative, in 1580 (95%, 83 (5% patients, respectively. A higher incidence of complications was found in conservatively treated patients. As a conclusion, in the last 10 years, vigorous sexual intercourse was the commonest etiology of penile fracture in the Middle East and Central Asia regions. Surgery remains the preferred treatment option for patients diagnosed with penile fracture.

[The population and economic problems of South Asia].

Gu, J

1983-07-29

South Asia, which includes Central South Asia, Southeast Asia, and Southwest Asia, had a comparatively higher population growth rate during the 30-year postwar period because of the overall backward economy and strong religious tradition. From the viewpoint of economics, the high population growth in South Asia has slowed down economic growth, increased the foreign trade imblance, and worsened poverty. Secondly, the rapid population growth has overburdened the area's educational system. The illiteracy rate has been going up continuously because of inadequate funds available for education. Thirdly, young labor is lacking in skills, training, and work experience, and related productivity has declined. Consequently, profits, the investment capability, and wages are also declining. The problems of the oversupply of labor, unemployment, and poverty have also become increasingly serious. In addition, the rapid population growth has intensified the pressure on the food supply and worsened the average nutrition of the general public. In recent years, countries in South Asia have been trying to deal with various problems caused by the rapid population growth. Measures have been taken to control the population growth, with a redistribution of the population to places outside cities, and export labor to oil-producing nations of the Middle East and Africa in order to solve the problem of the domestic labor surplus and earn more income for the foreign exchange. Countries in South Asia need more time and effort to achieve a balance between the population growth and economic development.

Ono, H S; Kawamura, T

1991-06-01

This study identifies characteristics of the geographical distribution of sensible climates and their diurnal and annual variations, and presents a classification of bioclimates in monsoon Asia by using Kawamura's discomfort index formula. During the hottest month, tropical areas and areas in central and South China are uncomfortable for humans throughout the day and night, and temperate zones in lowlands are uncomfortable during the daytime. Tropical zones are uncomfortable all year long and temperate zones in lowlands are uncomfortable during summer. Four climatic types were distinguished in monsoon Asia. Climatic type I, hyperthermal throughout the year, occurs in the tropics south of latitude 20 degrees N. Climatic type II, hyperthermal in the hottest month and comfortable in the coldest month, extends over latitudes from 20 degrees to 30 degrees N except in the highlands. Climatic type III, hyperthermal in the hottest month and hypothermal in the coldest month, encompasses temperate zones of East Asia and subtropical arid areas of northwestern India. Climatic type V, comfortable in the hottest month and hypothermal in coldest month, occurs near the southeast coast of the Soviet Union and in the highlands of the Himalayas.

Isolated communities in remote regions of Afghanistan, Kyrgyz Republic, Pakistan and Tajikistan lack access to high-quality, low-cost health care services, forcing them to travel to distant parts of the country, bearing an unnecessary financial burden. The eHealth Programme under Central Asia Health Systems Strengthening (CAHSS) Project, a joint initiative between the Aga Khan Foundation, Canada and the Government of Canada, was initiated in 2013 with the aim to utilize Information and Communication Technologies to link health care institutions and providers with rural communities to provide comprehensive and coordinated care, helping minimize the barriers of distance and time. Under the CAHSS Project, access to low-cost, quality health care is provided through a regional hub and spoke teleconsultation network of government and non-government health facilities. In addition, capacity building initiatives are offered to health professionals. By 2017, the network is expected to connect seven Tier 1 tertiary care facilities with 14 Tier 2 secondary care facilities for teleconsultation and eLearning. From April 2013 to September 2014, 6140 teleconsultations have been provided across the project sites. Additionally, 52 new eLearning sessions have been developed and 2020 staff members have benefitted from eLearning sessions. Ethics and patient rights are respected during project implementation.

Eolian dust dispersal patterns since the last glacial period in eastern Central Asia: insights from a loess-paleosol sequence in the Ili Basin

Full Text Available The extensive loess deposits of the Eurasian mid-latitudes provide important terrestrial archives of Quaternary climatic change. As yet, however, loess records in Central Asia are poorly understood. Here we investigate the grain size and magnetic characteristics of loess from the Nilka (NLK section in the Ili Basin of eastern Central Asia. Weak pedogenesis suggested by frequency-dependent magnetic susceptibility (χfd% and magnetic susceptibility (MS peaks in primary loess suggest that MS is more strongly influenced by allogenetic magnetic minerals than pedogenesis, and may therefore be used to indicate wind strength. This is supported by the close correlation between variations in MS and proportions of the sand-sized fraction. To further explore the temporal variability in dust transport patterns, we identified three grain size end-members (EM1, mode size 47.5 µm; EM2, 33.6 µm; EM3, 18.9 µm which represent distinct aerodynamic environments. EM1 and EM2 are inferred to represent grain size fractions transported from proximal sources in short-term, near-surface suspension during dust outbreaks. EM3 appears to represent a continuous background dust fraction under non-dust storm conditions. Of the three end-members, EM1 is most likely the most sensitive recorder of wind strength. We compare our EM1 proportions with mean grain size from the Jingyuan section in the Chinese loess plateau, and assess these in the context of modern and Holocene climate data. Our research suggests that the Siberian High pressure system is the dominant influence on wind dynamics, resulting in loess deposition in the eastern Ili Basin. Six millennial-scale cooling (Heinrich events can be identified in the NLK loess records. Our grain size data support the hypothesis that the Siberian High acts as teleconnection between the climatic systems of the North Atlantic and East Asia in the high northern latitudes, but not for the mid-latitude westerlies.

The desert and semi-desert region of arid central Asia is one of the most important areas of middle-latitude dust emission and deposition in the Northern Hemisphere. Marine isotope stage 2 (MIS 2) was the latest and one of the most representative intervals of dust emission from the region, and it is especially important for research into processes of dust transportation and deposition. Here, we report the results of an optically stimulated luminescence study of the Hoalin section in southern Tajikistan, which was deposited during MIS 2. The fine-grained quartz single aliquot regeneration (SAR) approach was used and its reliability was verified by internal checks. In addition, grain-size analyses, calculated dust accumulation rates (DARs) and mass accumulation rates (MARs) were used to reconstruct the pattern of climate change during MIS 2. The mean DAR for southern Tajikistan during MIS 2 was 0.43 m/ka, and the corresponding average MAR was 673 g/cm2/a for a non-river-terrace site, which is higher than the average MARs estimated for the central and southern Chinese Loess Plateau (CLP). In contrast to previous suggestions, the high dust DARs and MARs during the LGM indicate a 'cold-dry' climatic pattern, rather than a 'cold-humid' pattern. Our results also confirm that the patterns of high dust emission and deposition during the LGM in the mid-latitude arid zone of Asia were synchronous.

Full Text Available This paper uses a probit and dprobit model to examine the domestic determinants of corruption in Eastern Europe and Central Asia. In addition, it also looks at whether economic links with a country that is perceived as corrupt—Russia—leads to an increase or decrease in the level of domestic corruption. Using a dataset at the firm level provided by the World Bank, this paper finds that the “Control Rights Hypothesis,” the “Bargaining Power Hypothesis”, and the “Grease the Wheels Hypothesis” are statistically significant at the domestic level and also shows that increased commerce links with Russia leads to a statistically significant correlation with the instance of corruption via the “Grease the Wheels Hypothesis” channel.

Allergic conjunctivitis in Asia.

Science.gov (United States)

Thong, Bernard Yu-Hor

2017-04-01

Allergic conjunctivitis (AC), which may be acute or chronic, is associated with rhinitis in 30%-70% of affected individuals, hence the term allergic rhinoconjunctivitis (AR/C). Seasonal and perennial AC is generally milder than the more chronic and persistent atopic and vernal keratoconjunctivitis. Natural allergens like house dust mites (HDM), temperate and subtropical grass and tree pollen are important triggers that drive allergic inflammation in AC in the Asia-Pacific region. Climate change, environmental tobacco smoke, pollutants derived from fuel combustion, Asian dust storms originating from central/north Asia and phthalates may also exacerbate AR/C. The Allergies in Asia Pacific study and International Study of Asthma and Allergies in Childhood provide epidemiological data on regional differences in AR/C within the region. AC significantly impacts the quality of life of both children and adults, and these can be measured by validated quality of life questionnaires on AR/C. Management guidelines for AC involve a stepped approach depending on the severity of disease, similar to that for allergic rhinitis and asthma. Topical calcineurin inhibitors are effective in certain types of persistent AC, and sublingual immunotherapy is emerging as an effective treatment option in AR/C to grass pollen and HDM. Translational research predominantly from Japan and Korea involving animal models are important for the potential development of targeted pharmacotherapies for AC.

Full Text Available Examining the situation in Central Asia (Kazakhstan, Tayikistan, Kyrgyzstan, Turkmenistan and Uzbekistan is an interesting excercice in order to analyze the evolution of the international environmental security concept. As an exemple of how environmental changes may come to acquire an entity such as to be perceived as a threat when they combine with inequitable allocation of resources, we focus on shared water resources management. The framework at international level should be the two main instruments in this field, the 1992 Convention on the Protection and Use of Transboundary Watercourses and International Lakes and the 1997 Convention on the Law of the Non-navigational Uses of International Watercourses. On the one hand, Central Asian States have shown only a weak commitment to these international regimes. On the contrary, they have prioritized the former URSS’s model of water and energy exchange. This model, as being unsustainable and inequitable, favors the extreme dichotomy between the two major competing uses of water in the region (irrigation and hydropower production. On the other hand, some sub-regional institutions served to clarify the articulation of water management structures. However, because of important issues on their internal organization, they have not been able to achieve their mission and their efforts seems to be directed to seek stability and the status quo in Central Asia.

Asia: point of no return?

Perhaps 1 million people in Asia are HIV positive (1% of the world's total). Even many more people are at risk since Asia has 50% of the world's population. Sexual transmission is the main mode of transmission. Yet people in Asia do not want to deal with sexual behavior. Thus high level political commitment is needed such has been done in Thailand which has set up a national AIDS committee. An AIDS expert predicts that by 1995 the number of HIV positive individuals in Asia will surpass the number of HIV positive individuals in all the developed countries. India, Myanmar, and Thailand where prostitution and intravenous (IV) drug use abounds (the Golden Triangle) suffer from the worst AIDS epidemics in the region. International sex tourism contributes greatly to both the heterosexual and homosexual spread of AIDS. In fact, the national AIDS committee in Thailand has begun a campaign to stop sex tourism, but as of September 1991, it had no effect. Further some sex businesses have attempted to stop the spread of AIDS. For example, 2 brothels in central Thailand have implemented a condom only policy for their clients. High rates of sexually transmitted diseases among prostitutes facilitate HIV transmission. This highlights the need for Asian countries to promote condom use. Not all of the Asian countries screen 100% of their blood and blood products. In fact, in India, commercial blood banks do not always screen donated blood since screening eats into their profits. Further unsterile needles are often used in medical facilities such as in India and Viet Nam. Hong Kong sells inexpensive sterile needles over the counter which may account for its low HIV positive rate among drug users. Despite the many problems in Asia which facilitate HIV transmission, tragedy can be averted if governments act at once.

The approach to emerging energy markets in Asia of Enron, one of the major independent producers and developers of natural gas, is described. The interest of the company has been stimulated both by the availability of gas resources in Asia and the interest shown in many countries in using natural gas as a fuel for power generation. Possibilities for development are being created by plans for major new pipelines from Russia and the central Asian states and the availability of liquefied natural gas. (UK)

Smoke haze, caused by vegetation and peat fires in Southeast Asia, is of major concern because of its adverse impact on regional air quality. We apply two different methods (a chemical transport model and a Lagrangian atmospheric transport model) to identify the locations of fires contributing to the increased mass concentration of particulate matter with diameters less than 2.5 μm (PM 2.5 ) in Singapore over the period 2004–09. We find that fires in southern Sumatra account for the greatest percentage of the total fire enhancement to PM 2.5 concentrations in Singapore (42–62%), with fires in central Sumatra and Kalimantan contributing 21–35% and 14–15%, respectively. Furthermore, we find that fires in these regions also increase PM 2.5 concentrations in other major cities across Southeast Asia. Our results suggest that acting to reduce fires in southern and central Sumatra (specifically in the eastern parts of the provinces of Jambi, South Sumatra, Lampung and Riau) and southwest Kalimantan (the southern extent of the provinces of West, Central and South Kalimantan) would have the greatest benefit to particulate air quality in Singapore and more widely across Southeast Asia.

For working out and proposing project themes optimum for the popularization of technologies for effectively utilizing energy in four countries in Central Asia (Kazakhstan, Uzbekistan, Turkmenistan, and Azerbaijan), basic surveys were conducted into their energy policies, trends of supply and demand, electric power industry, metal refining industry, and cement making industry. Common to the four nations were that they were rich in energy resources (natural gas, oil, and coal) but that they failed to utilize them effectively despite of an increase in the yields. Incomplete infrastructures and delay in the implementation of energy measures attracted attention. A higher priority was found attached to the upgrading of and investment in structures, renewal of facilities, and the intensification of management. The basic industries wanted the modernization of their facilities and processes. As for electric power consumption, Kazakhstan consumed 53.0-billion kWh, Uzbekistan 39.0-billion kWh, Turkmenistan 4.4-billion kWh, and Azerbaijan 16.4-billion kWh. In Uzbekistan, where the nonferrous metal refining industry led its national economy, the energy consumption rate was found to be quite high. There was a decrease in production in the cement making industry. (NEDO)

Long-range transport and deposition of sulfur in Asia

Arndt, R.L.; Carmichael, G.R.

1995-01-01

The long range transport of sulfur in Asia is analyzed through the use of a multi-dimensional acid deposition model. The air quality of this region is heavily influenced by the combination of Asia's growing population, its expanding economy, and the associated systems of energy consumption and production. These factors combined with a shift to using indigenous coal as the primary fuel source for the region, will result in increased emissions of pollutants into the environment. By the year 2020 sulfur emissions from Asia are projected to exceed the combined emissions from Europe and North America. The authors have estimated sulfur deposition in Asia on a one-by-one degree spatial resolution in the region from Pakistan to Japan and from Indonesia to Mongolia using a 3-layer Lagrangian model. Deposition in excess of 10 g S/m 2 is predicted in south-central China. The relationship between emission source and receptor has been developed into a deposition matrix and examples of the source-receptor relationship are presented. 11 refs., 2 figs., 2 tabs

The semi-arid regions of Central Asia crucially depend on the water resources supplied by the mountainous areas of the Tien-Shan and Pamirs. During the summer months the snow and glacier melt dominated river discharge originating in the mountains provides the main water resource available for agricultural production, but also for storage in reservoirs for energy generation during the winter months. Thus a reliable seasonal forecast of the water resources is crucial for a sustainable management and planning of water resources. In fact, seasonal forecasts are mandatory tasks of all national hydro-meteorological services in the region. In order to support the operational seasonal forecast procedures of hydromet services, this study aims at the development of a generic tool for deriving statistical forecast models of seasonal river discharge. The generic model is kept as simple as possible in order to be driven by available hydrological and meteorological data, and be applicable for all catchments with their often limited data availability in the region. As snowmelt dominates summer runoff, the main meteorological predictors for the forecast models are monthly values of winter precipitation and temperature as recorded by climatological stations in the catchments. These data sets are accompanied by snow cover predictors derived from the operational ModSnow tool, which provides cloud free snow cover data for the selected catchments based on MODIS satellite images. In addition to the meteorological data antecedent streamflow is used as a predictor variable. This basic predictor set was further extended by multi-monthly means of the individual predictors, as well as composites of the predictors. Forecast models are derived based on these predictors as linear combinations of up to 3 or 4 predictors. A user selectable number of best models according to pre-defined performance criteria is extracted automatically by the developed model fitting algorithm, which includes a test

Background One fifth of Kazakhstan’s population is labor migrants working in poor conditions with limited legal rights. This paper examines self-rated health, mental health and access to health care among migrant workers. Methods Using geo-mapping, a random sample of internal and external migrant market workers was selected in Almaty (N=450). We used survey logistic regression adjusted for clustering of workers within stalls. Results Almost half of participants described their health as fair or poor and reported not seeing a doctor when needed, 6.2% had clinical depression and 8.7% met criteria for alcohol abuse. Female external migrants were at higher risk for poor health and underutilization of health services. High mobility was associated with depression among internal migrants and with alcohol abuse among female migrant workers. Conclusions This study demonstrates the urgent need to address health and mental health needs and improve access to health care among labor migrants in Central Asia. PMID:24186359

Comprehensive measurements of atmospheric aerosols were made in Phimai, central Thailand (15.183°N, 102.565°E, elevation: 206 m) during the BASE-ASIA field experiment from late February to early May in 2006. The observed aerosol loading was sizable for this rural site (mean aerosol scattering: 108 ± 64 Mm-1; absorption: 15 ± 8 Mm-1; PM10 concentration: 33 ± 17 μg m-3), and dominated by submicron particles. Major aerosol compounds included carbonaceous (OC: 9.5 ± 3.6 μg m-3; EC: 2.0 ± 2.3 μg m-3) and secondary species (SO42-: 6.4 ± 3.7 μg m-3, NH4+: 2.2 ± 1.3 μg m-3). While the site was seldom under the direct influence of large forest fires to its north, agricultural fires were ubiquitous during the experiment, as suggested by the substantial concentration of K+ (0.56 ± 0.33 μg m-3). Besides biomass burning, aerosols in Phimai during the experiment were also strongly influenced by industrial and vehicular emissions from the Bangkok metropolitan region and long-range transport from southern China. High humidity played an important role in determining the aerosol composition and properties in the region. Sulfate was primarily formed via aqueous phase reactions, and hygroscopic growth could enhance the aerosol light scattering by up to 60%, at the typical morning RH level of 85%. The aerosol single scattering albedo demonstrated distinct diurnal variation, ranging from 0.86 ± 0.04 in the evening to 0.92 ± 0.02 in the morning. This experiment marks the first time such comprehensive characterization of aerosols was made for rural central Thailand. Our results indicate that aerosol pollution has developed into a regional problem for northern Indochina, and may become more severe as the region's population and economy continue to grow.

Among natural gas producing nations, there has been some concern about how the Asia Pacific will meet future demand for energy. We argue that natural gas, both regional and global, will play a vital role. Estimates of potential gas consumption in the region are analyzed and used to develop consensus projections to 2030. These consumption profiles are compared with gas supply estimates including indigenous, pipeline and LNG for the Asia Pacific market. From this analytical framework, we find that demand will be sufficiently large to accommodate supplies from diverse sources including North America, the Middle East, Central Asia, Russia, and the Asia Pacific itself. An important policy implication is that gas producing and consuming nations should benefit from promoting gas trade and not be concerned about a situation of potential lack of demand coupled with oversupply. - Highlights: • Estimates of gas consumption in the Asia Pacific (AP) in 2030 are presented. • Compared with supply estimates for AP including indigenous, pipeline, and LNG. • Find that demand in AP large enough to accommodate supply from all regions. • Nations should promote gas trade policy and not be overly concerned about oversupply

Full Text Available Through the application and use of geospatial data, this study aimed to detect and characterize some of the key environmental drivers contributing to landscape-scale vegetation response patterns in Central Asia. The objectives of the study were to identify the variables driving the year-to-year vegetation dynamics in three regional landscapes (desert, steppe, and mountainous; and to determine if the identified environmental drivers can be used to explain the spatial-temporal variability of these spatio-temporal dynamics over time. It was posed that patterns of change in terrestrial phenology, derived from the 8 km bi-weekly time series of Normalized Difference Vegetation Index (NDVI data acquired by the Advanced Very High Resolution Radiometer (AVHRR satellites (1981–2008, can be explained through a multi-scale analysis of a suite of environmental drivers. Multiple linear stepwise regression analyses were used to test the hypotheses and address the objectives of the study. The annually computed phenological response variables or pheno-metricstime (season start, season length, and an NDVI-based productivity metric were modeled as a function of ten environmental factors relating to soil, topography, and climate. Each of the three studied regional landscapes was shown to be governed by a distinctive suite of environmental drivers. The phenological responses of the steppe landscapes were affected by the year-to-year variation in temperature regimes. The phenology of the mountainous landscapes was influenced primarily by the elevation gradient. The phenological responses of desert landscapes were demonstrated to have the greatest variability over time and seemed to be affected by soil carbon content and year-to-year variation of both temperature regimes and winter precipitation patterns.

Full Text Available Studying locations of strong earthquakes (М≥8 in space and time in Central Asia has been among top prob-lems for many years and still remains challenging for international research teams. The authors propose a new ap-proach that requires changing the paradigm of earthquake focus – solid rock relations, while this paradigm is a basis for practically all known physical models of earthquake foci. This paper describes the first step towards developing a new concept of the seismic process, including generation of strong earthquakes, with reference to specific geodynamic features of the part of the study region wherein strong earthquakes were recorded in the past two centuries. Our analysis of the locations of М≥8 earthquakes shows that in the past two centuries such earthquakes took place in areas of the dynamic influence of large deep faults in the western regions of Central Asia. In the continental Asia, there is a clear submeridional structural boundary (95–105°E between the western and eastern regions, and this is a factor controlling localization of strong seismic events in the western regions. Obviously, the Indostan plate’s pressure from the south is an energy source for such events. The strong earthquakes are located in a relatively small part of the territory of Central Asia (i.e. the western regions, which is significantly different from its neighbouring areas at the north, east and west, as evidenced by its specific geodynamic parameters. (1 The crust is twice as thick in the western regions than in the eastern regions. (2 In the western regions, the block structures re-sulting from the crust destruction, which are mainly represented by lense-shaped forms elongated in the submeridio-nal direction, tend to dominate. (3 Active faults bordering large block structures are characterized by significant slip velocities that reach maximum values in the central part of the Tibetan plateau. Further northward, slip velocities decrease

Despite the demonstrated efficacy of etanercept for the treatment of ankylosing spondylitis (AS), sulfasalazine is often prescribed, especially in countries with limited access to biologic agents. The objective of this subset analysis of the ASCEND trial was to compare the efficacy of etanercept and sulfasalazine in treating patients with AS from Asia, Eastern/Central Europe, and Latin America. A total of 287 patients, 190 receiving etanercept 50 mg once weekly and 97 receiving sulfasalazine 3 g daily, from eight countries were included in this subset analysis. Differences in disease activity and patient-reported outcomes assessing health-related quality-of-life (HRQoL) parameters in response to treatment were analyzed using the Cochran-Mantel-Haenszel test for categorical efficacy endpoints and analysis of covariance model for continuous variables. At week 16, a significantly greater proportion of patients receiving etanercept achieved ASAS20 (79.0 %) compared with patients receiving sulfasalazine (61.9 %; p = 0.002). At week 16, treatment with etanercept also resulted in significantly better responses than sulfasalazine for ASAS40 (64.7 vs. 35.1 %; p Disease Activity Index (65.8 vs. 42.3 %; p Asia, Central/Eastern Europe, and Latin America.

Cancer incidence and mortality varies across region, sex and country's economic status. While most studies focused on global trends, this study aimed to describe and analyse cancer incidence and mortality in Asia, focusing on cancer site, sex, region and income status. Age-standardised incidence and mortality rates of cancer were extracted from the GLOBOCAN 2012 database. Cancer mortality to incidence ratios (MIRs) were calculated to represent cancer survival. The data were analysed based on the four regions in Asia and income. Cancer incidence rate is lower in Asia compared to the West but for MIR, it is the reverse. In Asia, the most common cancers in men are lung, stomach, liver, colorectal and oesophageal cancers while the most common cancers in women are breast, lung, cervical, colorectal and stomach cancers. The MIRs are the highest in lung, liver and stomach cancers and the lowest in colorectal, breast and prostate cancers. Eastern and Western Asia have a higher incidence of cancer compared to South-Eastern and South-Central Asia but this pattern is the reverse for MIR. Cancer incidence rate increases with country income particularly in colorectal and breast cancers but the pattern is the opposite for MIR. This study confirms that there is a wide variation in cancer incidence and mortality across Asia. This study is the first step towards documenting and explaining the changing cancer pattern in Asia in comparison to the rest of the world.

Humans have been changing the LCLU dynamics over time through the world. In the Central Asia region, these changes have been especially pronounced due to the political and economic transformation. We present a detailed analysis, focusing on identifying and quantifying the anthropogenic signature in the water and land use across the region. We have characterized the anthropogenic dust emission by combining the modeling and observations. The model is a fully coupled model called WRF-Chem-DuMo that takes explicitly into account the vegetation treatment in modeling the dust emission. We have reconstructed the anthropogenic dust sources in the region, such as the retreat of the Aral Sea, changes in agricultural fields, etc. In addition, we characterize the anthropogenic water use dynamics, including the changes in the water use for the agricultural production. Furthermore, we perform an analysis to identify the anthropogenic signature in the NDVI pattern. The NDVI were analyzed in conjunction with the meteorological fields that were simulated at the high special resolution using the WRF model. Meteorological fields of precipitation and temperature were used for the correlation analysis to separate the natural vs. anthropogenic changes. In this manner, we were able to identify the regions that have been affected by human activities. We will present the quantitative assessment of the anthropogenic changes. The diverse consequences for the economy of the region, as well as, the environment will be addressed.

Comparison of GPS and Quaternary slip rates: Insights from a new Quaternary fault database for Central Asia

Mohadjer, Solmaz; Ehlers, Todd; Bendick, Rebecca; Mutz, Sebastian

2016-04-01

Previous studies related to the kinematics of deformation within the India-Asia collision zone have relied on slip rate data for major active faults to test kinematic models that explain the deformation of the region. The slip rate data, however, are generally disputed for many of the first-order faults in the region (e.g., Altyn Tagh and Karakorum faults). Several studies have also challenged the common assumption that geodetic slip rates are representative of Quaternary slip rates. What has received little attention is the degree to which geodetic slip rates relate to Quaternary slip rates for active faults in the India-Asia collision zone. In this study, we utilize slip rate data from a new Quaternary fault database for Central Asia to determine the overall relationship between Quaternary and GPS-derived slip rates for 18 faults. The preliminary analysis investigating this relationship uses weighted least squares and a re-sampling analysis to test the sensitivity of this relationship to different data point attributes (e.g., faults associated with data points and dating methods used for estimating Quaternary slip rates). The resulting sample subsets of data points yield a maximum possible Pearson correlation coefficient of ~0.6, suggesting moderate correlation between Quaternary and GPS-derived slip rates for some faults (e.g., Kunlun and Longmen Shan faults). Faults with poorly correlated Quaternary and GPS-derived slip rates were identified and dating methods used for the Quaternary slip rates were examined. Results indicate that a poor correlation between Quaternary and GPS-derived slip rates exist for the Karakorum and Chaman faults. Large differences between Quaternary and GPS slip rates for these faults appear to be connected to qualitative dating of landforms used in the estimation of the Quaternary slip rates and errors in the geomorphic and structural reconstruction of offset landforms (e.g., offset terrace riser reconstructions for Altyn Tagh fault

Laws, Institutions and Transboundary Pasture Management in the High Pamir and Pamir-Alai Mountain Ecosystem of Central Asia

2012-06-01

Full Text Available Enhanced rangeland governance is a priority for the governments of the post-Soviet Central Asian states of the Kyrgyz Republic and Tajikistan. Major transitional challenges confront the newly independent states of Central Asia. These challenges include the withdrawal of subsidies previously provided by the centralised Soviet government; moves towards privatisation and the conversion of administrative boundaries to international boundaries. In this context transboundary approaches to rangeland management are essential. This paper highlights the challenges for effective pasture management in the Pamir, Pamir-Alai ecosystem; the inadequacies of pasture-related legal instruments and the absence of institutions for the implementation of these instruments. Transboundary management is hampered by the lack of agreements between the two countries and the differences between national level laws and institutions. Meaningful transboundary agreements and the harmonization of national level laws would be a significant step towards achieving sustainable transboundary pasture management. However, on their own these legal tools are insufficient. Long-term effective pasture management in the Pamir, Pamir-Alai ecosystem necessitates that the causes of degradation are addressed. Mountain communities would also need to be convinced of economic and other benefits before current resource-use practices could be expected to change. Institutional and capacity building and adequate funding are also fundamental to ensuring the effectiveness of any legal instruments that are developed and any strategies that are employed.

Long highly-resolved proxies for runoff are in high demand for hydrological forecasts and water management in arid Central Asia. An accurate (R2 = 0.53) reconstruction of October-September discharge of the Ili River in Kazakhstan, 1779-2015, is developed from moisture-sensitive tree rings of spruce sampled in the Tian Shan Mountains. The fivefold extension of the gauged discharge record represents the variability of runoff in the Lake Balkhash Basin for the last 235 years. The reconstruction shows a 40 year long interval of low discharge preceded a recent high peak in the first decade of the 2000s followed by a decline to more recent levels of discharge not seen since the start of the gauged record. Most reconstructed flow extremes (± 2σ) occur outside the instrumental record (1936-2015) and predate the start of large dam construction (1969). Decadal variability of the Ili discharge corresponds well with hydrological records of other Eurasian internal drainages modeled with tree rings. Spectral analysis identifies variance peaks (highest near 42 year) consistent with main hemispheric oscillations of the Eurasian climatic system. Seasonal comparison of the Ili discharge with sea-level-pressure and geopotential height data suggests periods of high flow likely result from the increased contribution of snow to runoff associated with the interaction of Arctic air circulation with the Siberian High-Pressure System and North Atlantic Oscillation.

Full Text Available China's footprints in Afghanistan are vied by many, both, friends and rivals as it cautiously reveals its geostrategic goals. It would like to emulate the African and Central Asian success story in Afghanistan as well, which is not terra incognito. Afghanistan has been the fulcrum of geopolitical balance of power during the Cold war days. China's Afghanistan policy (CAP is marked by its insecurities of terrorism, extremism and separatism in Xinjiang province. It has heavily invested in procuring Central Asian energy resources. Both, the concerns go well in formulation of CAP. However, the presence of the US and Russia make the scenario competitive, where its ‘Peaceful Rise’ may be contested. Besides, China sees South Asian Region as its new Geoeconomic Frontier. All these concerns get factored into CAP. It remains to be seen what options partake in CAP, as China prepares for durable presence in Afghanistan in the long run.

Full Text Available The deep structure and paleogeodynamics of the Siberian craton and the Central Asian folded belt are studied by two specialized laboratories of the Institute of the Earth’s Crust, SB RAS – the Laboratory of Complex Geophysics and the Laboratory of Paleogeodynamics. A variety of modern geophysical methods is applied. Surface wave tomography is focused on determination of 3D velocity structure of the upper mantle. Seismic, gravimetric and electrical surveys are aimed at stu­dies of structures of the crust and the upper mantle. Geothermic parameters of the lithosphere in Central Asia are measured. In search for mineral resources, new geophysical prospecting technologies are developed. Quality paleogeodynamics reconstructions require a proper understanding of the structural evolution of the Siberian craton and the Central Asian folded belt. Researches in this scientific field are conducted by the Laboratory of Paleogeodynamics. Besides, the Laboratory studies new minerals and conditions of their formation. Some of the scientific research projects are jointly implemented by the two laboratories, and research results are regularly published in Russia and abroad.

A series of statistics describing seasonal Snow Cover Extent and timing in Central Asia (CA) have been derived from AVHRR satellite images for the time period from 1986 to 2008. Analysis of long term mean snow cover statistics shows that the area weighted mean of long term Snow Covering Days (SCD) for the whole CA is 95.2 ± 65.7 days. High elevation mountainous areas above 3000 m in Altai, Tien Shan and Pamir, which account for about 2.8% of total area in CA, have SCD > 240 days. Deserts (Karakorum Desert, Taklamakan Desert, Kumtag Desert) and rain shadow areas of major mountains, accounting for 27.0% of total area in CA, have SCD in the range of 0-30 days. Factors affecting snow cover distribution have been analyzed using simple linear regression and segmented regression. For plain regions and windward regions, the SCD rate is + 5.9 days/100 m, while for leeward regions, the rate jumps from + 0.7 days/100 m to + 10.0 days/100 m at about 2335 m. Latitude affects the SCD, especially in plain regions with insignificant change of elevation, with rates of 9-10 days/degree from south to north. The Mann-Kendal test and the Theil-Sen regression methods have been applied to analyze the spatial heterogeneous trends of change of SCD, Snow Cover Onset Date (SCOD), and Snow Cover Melt Date (SCMD). Area weighed mean SCD in the whole CA does not exhibit significant trend of change from 1986 to 2008. Increase of SCD was observed in the northeastern Kazakh Steppe. Low elevation areas below 2000 m in Central Tien Shan and Eastern Tien Shan, as well as mid-elevation areas from 1000 m to 3000 m in Western Tien Shan, Pamiro-Alai and Western Pamir, also experienced increase of SCD, associated with both earlier SCOD and later SCMD. Decrease of SCD was observed in mountainous areas of Altai, Tien Shan and Pamir, and vast areas in plains surrounding the Aral Sea.

The paper offers specific inputs to the debate on local content promotion in the oil industries of West Africa and Central Asia. To this end, we document the international experience with local content promotion to derive best practices in the field. We then use a case study approach to devise a simple analytical framework for rationalizing the selection of viable sectors for local content promotion, in an attempt to make operational one of the best practice principles (efficiency) developed before. By proposing specific rules regarding the acceptability of a project, the analysis seeks to add rigor and address distortions on localization outcomes from rent-seeking. The emphasis is not on supporting efforts to 'pick winners' and subsidize them through a range of by and large discredited instruments. Rather, the paper focuses on the specific public inputs the government would have to provide to support an otherwise market-driven process

Archaeological research in Central Eurasia is exposing unprecedented scales of trans-regional interaction and technology transfer between East Asia and southwest Asia deep into the prehistoric past. This article presents a new archaeobotanical analysis from pastoralist campsites in the mountain and desert regions of Central Eurasia that documents the oldest known evidence for domesticated grains and farming among seasonally mobile herders. Carbonized grains from the sites of Tasbas and Begash illustrate the first transmission of southwest Asian and East Asian domesticated grains into the mountains of Inner Asia in the early third millennium BC. By the middle second millennium BC, seasonal camps in the mountains and deserts illustrate that Eurasian herders incorporated the cultivation of millet, wheat, barley and legumes into their subsistence strategy. These findings push back the chronology for domesticated plant use among Central Eurasian pastoralists by approximately 2000 years. Given the geography, chronology and seed morphology of these data, we argue that mobile pastoralists were key agents in the spread of crop repertoires and the transformation of agricultural economies across Asia from the third to the second millennium BC.

The colonization of Eurasia and Australasia by African modern humans has been explained, nearly unanimously, as the result of a quick southern coastal dispersal route through the Arabian Peninsula, the Indian subcontinent, and the Indochinese Peninsula, to reach Australia around 50 kya. The phylogeny and phylogeography of the major mitochondrial DNA Eurasian haplogroups M and N have played the main role in giving molecular genetics support to that scenario. However, using the same molecular tools, a northern route across central Asia has been invoked as an alternative that is more conciliatory with the fossil record of East Asia. Here, we assess as the Eurasian macrohaplogroup R fits in the northern path. Haplogroup U, with a founder age around 50 kya, is one of the oldest clades of macrohaplogroup R in western Asia. The main branches of U expanded in successive waves across West, Central and South Asia before the Last Glacial Maximum. All these dispersions had rather overlapping ranges. Some of them, as those of U6 and U3, reached North Africa. At the other end of Asia, in Wallacea, another branch of macrohaplogroup R, haplogroup P, also independently expanded in the area around 52 kya, in this case as isolated bursts geographically well structured, with autochthonous branches in Australia, New Guinea, and the Philippines. Coeval independently dispersals around 50 kya of the West Asia haplogroup U and the Wallacea haplogroup P, points to a halfway core area in southeast Asia as the most probable centre of expansion of macrohaplogroup R, what fits in the phylogeographic pattern of its ancestor, macrohaplogroup N, for which a northern route and a southeast Asian origin has been already proposed.

of the Paleo-Pacific Ocean. Several world-class Cu-(Mo)-porphyry, Cu-Pb-Zn VMS and intrusion-related Au mineral camps, which formed in the Altaids at this stage, coincided with the episodes of plate reorganization and oroclinal bending of magmatic arcs. Major Pb-Zn and Cu sedimentary rock-hosted deposits of Kazakhstan and Central Asia formed in backarc rifts, which developed on the earlier amalgamated fragments. Major orogenic gold deposits are intrusion-related deposits, often occurring within black shale-bearing sutured backarc basins with oceanic crust. After amalgamation of the western Altaids, this part of the collage and adjacent cratons were affected by the Siberian superplume, which ascended at the Permian-Triassic transition. This plume-related magmatism produced various deposits, such as famous Ni-Cu-PGE deposits of Norilsk in the northwest of the Siberian craton. In the early Mesozoic, the eastern Altaids were oroclinally bent together with the overlapping Transbaikal magmatic arc in response to the northward migration and anti-clockwise rotation of the North China craton. The following collision of the eastern portion of the Altaid collage with the Siberian craton formed the Mongol-Okhotsk suture zone, which still links the accretionary wedges of central Mongolia and Circum-Pacific belts. In the late Mesozoic, a system of continent-scale conjugate northwest-trending and northeast-trending strike-slip faults developed in response to the southward propagation of the Siberian craton with subsequent post-mineral offset of some metallogenic belts for as much as 70-400 km, possibly in response to spreading in the Canadian basin. India-Asia collision rejuvenated some of these faults and generated a system of impact rifts.

To review all of epidemiological and etiological aspects of hepatocellular carcinoma (HCC) and examined the prevention of this disease in Asia. We conducted a systematic review according to the PRISMA guidelines. We were chosen articles that published previously, from PubMed (MEDLINE), the Cochrane database and Scopus. The key words used in this research were as follows: HCC in Asia and the way of prevention of this disease, with no language limitations. We selected those papers published before 2014 that we considered to be most important and appropriate. All relevant articles were accessed in full text and all relevant materials was evaluated and reviewed. More than 70% of all new cases of liver cancer were diagnosed in Asia, a region that 75% of all those chronically infected with hepatitis B virus (HBV) in the world. Chronic HBV infection is the main cause of HCC in Asia, where the virus is endemic and vertical transmission is common. Japan, Saudi Arabia, Egypt and Pakistan are exception because of high prevalence of HCV infection in these regions. The prevalence of this cancer is high in Eastern and South-Eastern Asia, But Middle Eastern countries are characterized as moderate prevalence rate of HCC region and Central Asia and some part of Middle Eastern countries are known as low prevalence rate of HCC. In addition of HBV and HCV the other factors such as aflatoxin, alcohol, obesity, diabetes and non-alcoholic fatty liver disease (NAFLD) might be responsible for a low prevalence of HCC in Asian countries. Currently available HCC therapies, chemotherapy, surgical are inefficient, mainly due to usually late diagnosis and high recurrence rates after surgical resection, and usually end with treatment failure. Liver transplantation also remains as a difficult strategy in patients with HCC. Thus prevention of HCC by treating and prevention HBV and HCV infection, the major causative agents of HCC, and the other risk factors such as aflatoxin, alcohol, obesity

Water is the most valuable resource in Central Asia and due to its uneven distribution and usage among the countries of the region it is also the main source of tension between upstream and downstream water users. Due to the rapidly shrinking glaciers in the Pamir, Tien-Shan and Alai mountains, the available water resources will, by 2030, be 30% lower than today while the water demand of the growing economies will increase by 30%. This will further aggravate the pressure on the water resources and increase the water deficit caused by an unsustainable water use and political agendas. These challenges can only be overcome by an integrated water resource management for the important transboundary river catchments. The basis for such an IWRM approach however needs to be a solid data base about the status quo of the water resources. To that end the research presented here provides a detailed overview of the transboundary Zarafshan River (Tajikistan-Uzbekistan), the lifeline for more than 6 mln people. The Zarafshan River is well suited for this as it is not only one of the most important rivers in Central Asia but because the public availability of hydrological and ecological data is very limited, Furthermore the catchment is characterized by the same imbalances in the Water-Energy-Food-Nexus as most river systems in that region, which makes the Zarafshan a perfect model river for Central Asia as a whole. The findings presented here are based on field measurements, existing data from the national hydrometeorological services and an extensive literature analysis and cover the status quo of the meteorological and hydrological characteristics of the Zarafshan as well as the most important water quality parameters (pH, conductivity, nitrate, phosphate, arsenic, chromate, copper, zinc, fluoride, petroleum products, phenols and the aquatic invertebrate fauna). The hydrology of the Zarafshan is characterized by a high natural discharge dynamic in the mountainous upper parts of

Korzeniewski, Krzysztof

Parasitic diseases of the gastrointestinal tract are a major health problem worldwide, especially in the Third World countries, where poor standards of hygiene and sanitation as well as the lack of medical care facilitate the spread of food and waterborne infections. To estimate the prevalence of intestinal parasitic infections in Central Asia on the example of the population inhabiting the Ghazni Province in eastern part of the country and to assess the validity of the WHO recommended mass deworming campaign carried out in Afghanistan. Taking into consideration the fact that hundreds of thousands of immigrants from Asia and Africa have recently been flooding into Europe, it has become necessary to investigate the epidemiology of intestinal parasitoses in areas characterized by different climatic conditions and poor standards of sanitation. The study was conducted in eastern Afghanistan between November 2011 and April 2014. Parasitological examination was performed on 3 different study groups: 110 soldiers from the Afghan National Army (adults), 1,167 patients hospitalized at the Ghazni Provincial Hospital (807 children and adolescents aged 1–18 and 360 adults), and 1,869 students (7–18 years) frequenting local schools. The study involved 3,146 people including: 2,248 females and 898 males; 2,676 children and adolescents (1–18 years) and 460 adults (19–85 years). Three stool samples were collected from each study subject at the intervals of 2 to 3 days. The samples were fixed in 10% formalin and then transported by air to the Department of Epidemiology and Tropical Medicine (Military Institute of Medicine) in Poland, where they were examined by light microscopy using 3 different diagnostic methods (direct smear in Lugol’s solution, decantation with distilled water, Fülleborn’s flotation). In total, 1,220 Afghans were found to be infected with pathogenic intestinal parasites (38.8%): 44/110 soldiers (40.0%), 322/807 hospitalized children and adolescents

The GEO-2000 study into alternative policy options for Europe and Central Asia focuses on energy use as an important driver for environmental problems across the region. The problems analyzed are climate change, acidification, summer smog, urban air pollution and risks of reactor accidents associated with nuclear power generation. The analysis includes the effects on biodiversity and population health. It considers the question of what can be achieved by moderate measures, and whether this will be enough. Similar Geo-2000 region-specific studies on alternative policies have been compiled other world regions. This report outliners the general methodology for these reports

GRAVITY ANOMALIES OF THE CRUST AND UPPER MANTLE FOR CENTRAL AND SOUTH ASIA

2016-01-01

Full Text Available Studying the density of both the crust and mantle is one of the topical problems in modern geophysics. Gravity modeling in combination with seismic tomography is an important tool for detecting density inhomogeneities in the crust and mantle, which can cause stresses and thus significantly impact the regional tectonics [Pogorelov, Baranov, 2010], especially in zones wherein continental margins actively interact with subducting oceanic plates and the entire depth of the tectonosphere is subject to stresses. Associated processes lead to considerable horizontal and vertical stresses that often cause catastrophic events on a global scale. The challenge of studying the global tectonic processes in the Earth’s tectonosphere can be addressed by gravity modeling in combination with seismic surveying.Data from previous studies. I.L. Nersesov et al. [1975] pioneered in calculating the spatial pattern of mantle density inhomogeneities in Central Asia. Although the accuracy of their estimations was not high due to the limited database, their study yielded significant results considering the structure of the crust. Numerous subsequent geophysical projects have researched the crust to a level sufficient to develop regional models, that can give quite adequate information on the depths of external and internal boundaries of the crust and suggest the distribution patterns of seismic velocities and density values. With reference to such data, mantle density inhomogeneities can be studied with higher accuracy.This paper reports on the estimations of gravity anomalies in the crust and upper mantle in Central and South Asia. The study region represents the full range of crust thicknesses and ages, as well a variety of crust formation types [Christensen, Mooney, 1995]. We used the 3D gravity modeling software package 3SGravity developed by Senachin [2015a, 2015b] that considers the spherical shape of the Earth's surface, and estimated gravitional anomalies using

Full Text Available The policy of “soft power” has lost some of its power in the Russian foreign policy, but continues to dominate in the minds of researchers. There are a lot of scientific and journalistic articles on this subject. The notion has already become a kind of trend, not only in the field of international relations and in the field of political science. The key criterion for determining the impact of “soft power” is “attraction”, that is how the subject can woo the object in order to have some influence on it. Both Russia and China have a set of instruments of “soft power”, which in varying degrees, allow them to influence the objects, including the countries of Central Asia, especially Kazakhstan. Due to the fact that the KR unofficially became the leader of the region, its example can be most clearly trace the desire of Russia and China to become the most attractive partner for Kazakhstan. The study is based on the Comparative Approach, which allows not only to identify the characteristics of the “soft power” of Russia and China, but to compare their effectiveness. The activities of the two countries is analyzed through the prism of tools used in the region of “soft power”, including investment, educational, scientific and cultural programs.

Central Asia has delivered significant paleoanthropological discoveries in the past few years. New genetic data indicate that at least two archaic human species met and interbred with anatomically modern humans as they arrived into northern Central Asia. However, data are limited: known archaeological sites with lithic assemblages generally lack human fossils, and consequently identifying the archaeological signatures of different human groups, and the timing of their occupation, remains elusive. Reliable chronologic data from sites in the region, crucial to our understanding of the timing and duration of interactions between different human species, are rare. Here we present chronologies for two open air Middle to Upper Palaeolithic (UP) sequences from the Tien Shan piedmont in southeast Kazakhstan, Maibulak and Valikhanova, which bridge southern and northern Central Asia. The chronologies, based on both quartz optically stimulated luminescence (OSL) and polymineral post-infrared infrared luminescence (pIR-IRSL) protocols, demonstrate that technological developments at the two sites differ substantially over the ∼47-19 ka time span. Some of the innovations typically associated with the earliest UP in the Altai or other parts of northeast Asia are also present in the Tien Shan piedmont. We caution against making assumptions about the directionality of spread of these technologies until a larger, better defined database of transitional sites in the region is available. Connections between the timing of occupation of regions, living area setting and paleoenvironmental conditions, while providing hypotheses worth exploring, remain inconclusive. We cautiously suggest a trend towards increasing occupation of open air sites across the Central Asian piedmont after ∼40 ka, corresponding to more humid climatic conditions which nevertheless included pulses of dust deposition. Human occupation persisted into the Last Glacial Maximum, despite cooler, and possibly drier

Vaginal yeast infections while deployed in Southwest/Central Asia, active component females, U.S. Armed Forces, 2008-2013.

2014-08-01

In field settings, female service members may not have adequate access to bathrooms, showers, laundry, or sanitary products necessary to maintain adequate feminine hygiene; therefore, service women may be at risk for vaginal yeast infections while deployed. During the 6-year surveillance period, nearly 3,000 U.S. military service women were diagnosed with at least one clinically significant yeast infection while supporting combat operations in Southwest/Central Asia. The crude overall incidence rate was 35.1 per 1,000 person-years (p-yrs). Overall incidence rates were higher among black, non-Hispanic service women, and among those in the Army and Air Force, in enlisted grades, and in communications/intelligence and motor transport occupations. The yearly rate of yeast infections was relatively stable from 2008 through 2010, then decreased in 2011 through 2013. Prior to deploying to austere operational settings, female service members should be provided practical and useful information, realistic training, and material support to decrease the risk of acquiring and increase the effectiveness of treating clinically and military operationally significant yeast infections.

-Baikal continent. The base of the Kazakhstan-Baikal continent was formed in the Vend-Cambrian due to subduction of the oceanic crust of the Paleo-Asian Ocean, including the Precambrian microcontinents and terrains of the Gondvana group, underneath the south-eastern margin of the Siberian continent (in the current coordinates. Due to subduction followed by collision of the microcontinents with the Kazakhstan-Tuva-Mongolia island arc, the crust had consolidated, and a complex continent was formed. Another major plate is the plate of the Paleo-Pacific Ocean. It is characterized by the long-term tectono-magmatic evolution without any involvement of the continental crust and by complex processes of the formation of the continental margins. Its evolution resulted in the formation of the Vend-Paleozoic continental margin complexes of the western segment of the Siberian continent which comprise the Vend-Cambrian Kuznetsk-Altai island arc and a complex of rocks of the Ordovic-Early Devonian passive margin and the Devon-Early Carbonic active margin. In the accretional wedges of the Kuznetsk-Altai island arc, abundant are only fragments of the Vend-Early Cambrian oceanic crust including ophiolites and paleo-oceanic uplifts. The contemporary analogue of the Central Asian folded belt is the south-eastern margin of Asia, represented by the junction area of the Indo-Australian and Pacific plates.

Asia is important as it accounts for more than half of the world population. The majority of Asian countries fall into the middle income category. As for cultural traditions, Asia is highly varied, with many languages spoken. The pattern of neurologic diseases in Asia is largely similar to the West, with some disease features being specific to Asia. Whereas Asia constitutes 60% of the world's population, it contains only 20% of the world's neurologists. This disparity is particularly evident in South and South East Asia. As for neurologic care, it is highly variable depending on whether it is an urban or rural setting, the level of economic development, and the system of health care financing. To help remedy the shortage of neurologists, most counties with larger populations have established training programs in neurology. These programs are diverse, with many areas of concern. There are regional organizations serving as a vehicle for networking in neurology and various subspecialties, as well as an official journal (Neurology Asia). The Asian Epilepsy Academy, with its emphasis on workshops in various locations, EEG certification examination, and fellowships, may provide a template of effective regional networking for improving neurology care in the region. © 2015 American Academy of Neurology.

Asia, which is characterized by monsoon climate and intense human activities, is one of the prominent understudied regions in terms of terrestrial carbon budgets and mechanisms of carbon exchange. To better understand terrestrial carbon cycle in Asia, we initiated multi-model and data intercomparison project in Asia (Asia-MIP). We analyzed outputs from multiple approaches: satellite-based observations (AVHRR and MODIS) and related products, empirically upscaled estimations (Support Vector Regression) using eddy-covariance observation network in Asia (AsiaFlux, CarboEastAsia, FLUXNET), ~10 terrestrial biosphere models (e.g. BEAMS, Biome-BGC, LPJ, SEIB-DGVM, TRIFFID, VISIT models), and atmospheric inversion analysis (e.g. TransCom models). We focused on the two difference temporal coverage: long-term (30 years; 1982-2011) and decadal (10 years; 2001-2010; data intensive period) scales. The regions of covering Siberia, Far East Asia, East Asia, Southeast Asia and South Asia (60-80E, 10S-80N), was analyzed in this study for assessing the magnitudes, interannual variability, and key driving factors of carbon cycles. We will report the progress of synthesis effort to quantify terrestrial carbon budget in Asia. First, we analyzed the recent trends in Gross Primary Productivities (GPP) using satellite-based observation (AVHRR) and multiple terrestrial biosphere models. We found both model outputs and satellite-based observation consistently show an increasing trend in GPP in most of the regions in Asia. Mechanisms of the GPP increase were analyzed using models, and changes in temperature and precipitation play dominant roles in GPP increase in boreal and temperate regions, whereas changes in atmospheric CO2 and precipitation are important in tropical regions. However, their relative contributions were different. Second, in the decadal analysis (2001-2010), we found that the negative GPP and carbon uptake anomalies in 2003 summer in Far East Asia is one of the largest

The Inylchek Glacier in Kyrgyzstan, Central Asia: Insight on Surface Kinematics from Optical Remote Sensing Imagery

Full Text Available Mountain chains of Central Asia host a large number of glaciated areas that provide critical water supplies to the semi-arid populated foothills and lowlands of this region. Spatio-temporal variations of glacier flows are a key indicator of the impact of climate change on water resources as the glaciers react sensitively to climate. Satellite remote sensing using optical imagery is an efficient method for studying ice-velocity fields on mountain glaciers. In this study, temporal and spatial changes in surface velocity associated with the Inylchek glacier in Kyrgyzstan are investigated. We present a detailed map for the kinematics of the Inylchek glacier obtained by cross-correlation analysis of Landsat images, acquired between 2000 and 2011, and a set of ASTER images covering the time period between 2001 and 2007. Our results indicate a high-velocity region in the elevated part of the glacier, moving up to a rate of about 0.5 m/day. Time series analysis of optical data reveals some annual variations in the mean surface velocity of the Inylchek during 2000–2011. In particular, our findings suggest an opposite trend between periods of the northward glacial flow in Proletarskyi and Zvezdochka glacier, and the rate of westward motion observed for the main stream of the Inylchek.

Potential corridors and barriers for plague spread in central Asia

Science.gov (United States)

2013-01-01

Background Plague (Yersinia pestis infection) is a vector-borne disease which caused millions of human deaths in the Middle Ages. The hosts of plague are mostly rodents, and the disease is spread by the fleas that feed on them. Currently, the disease still circulates amongst sylvatic rodent populations all over the world, including great gerbil (Rhombomys opimus) populations in Central Asia. Great gerbils are social desert rodents that live in family groups in burrows, which are visible on satellite images. In great gerbil populations an abundance threshold exists, above which plague can spread causing epizootics. The spatial distribution of the host species is thought to influence the plague dynamics, such as the direction of plague spread, however no detailed analysis exists on the possible functional or structural corridors and barriers that are present in this population and landscape. This study aims to fill that gap. Methods Three 20 by 20 km areas with known great gerbil burrow distributions were used to analyse the spatial distribution of the burrows. Object-based image analysis was used to map the landscape at several scales, and was linked to the burrow maps. A novel object-based method was developed – the mean neighbour absolute burrow density difference (MNABDD) – to identify the optimal scale and evaluate the efficacy of using landscape objects as opposed to square cells. Multiple regression using raster maps was used to identify the landscape-ecological variables that explain burrow density best. Functional corridors and barriers were mapped using burrow density thresholds. Cumulative resistance of the burrow distribution to potential disease spread was evaluated using cost distance analysis. A 46-year plague surveillance dataset was used to evaluate whether plague spread was radially symmetric. Results The burrow distribution was found to be non-random and negatively correlated with Greenness, especially in the floodplain areas. Corridors and

The Central Asian Orogenic Belt is a gigantic tectonic collage of numerous accreted terranes. However, its geodynamic evolution has been hotly debated primarily due to incomplete knowledge on the nature of these enigmatic terranes. This work presents new detrital zircon U-Pb and Hf isotopic data to constrain the crustal nature and origin of the Russian Altai, a critical segment of Altai-Mongolian terrane. The youngest zircon 206Pb/238U ages of 470 Ma constrain that the Terekta Formation, previously envisaged as Precambrian basement, was actually deposited after the Middle Ordovician. As for the three more sedimentary sequences above the Terekta Formation, they have youngest zircon 206Pb/238U ages of 425 Ma, 440 Ma and 380 Ma, respectively, indicating their depositions likely in the Late Silurian to Devonian. From all analyses, it is noted that many zircon U-Pb ages cluster at ca. 520 Ma and ca. 800 Ma, and these zircons display oscillatory zoning and have subhedral to euhedral morphology, which, collectively, suggests that adjacent Neoproterozoic to Paleozoic igneous rocks were possibly dominant in the sedimentary provenance. Additionally, a few rounded Archean to Mesoproterozoic zircon grains are characterized by complex texture, which are interpreted as recycling materials probably derived from the Tuva-Mongolian microcontinent. Precambrian rocks have not been identified in the Russian Altai, Chinese Altai and Mongolian Altai so far, therefore, Precambrian basement may not exist in the Altai-Mongolian terrane, but this terrane probably represents a large subduction-accretion complex built on the margin of the Tuva-Mongolian microcontinent in the Early Paleozoic. Multiple episodes of ridge-trench interaction may have caused inputs of mantle-derived magmas to trigger partial melting of the newly accreted crustal materials, which contributed to the accretionary complex. During accretionary orogenesis of the CAOB, formation of such subduction-accretion complex is

Can a change in cropping patterns produce water savings and social gains: A case study from the Fergana Valley, Central Asia

Full Text Available The study examines possible water savings by replacing alfalfa with winter wheat in the Fergana Valley, located upstream of the Syrdarya River in Central Asia. Agricultural reforms since the 1990s have promoted this change in cropping patterns in the Central Asian states to enhance food security and social benefits. The water use of alfalfa, winter wheat/fallow, and winter wheat/green gram (double cropping systems is compared for high-deficit, low-deficit, and full irrigation scenarios using hydrological modeling with the HYDRUS-1D software package. Modeling results indicate that replacing alfalfa with winter wheat in the Fergana Valley released significant water resources, mainly by reducing productive crop transpiration when abandoning alfalfa in favor of alternative cropping systems. However, the winter wheat/fallow cropping system caused high evaporation losses from fallow land after harvesting of winter wheat. Double cropping (i.e., the cultivation of green gram as a short duration summer crop after winter wheat harvesting reduced evaporation losses, enhanced crop output and hence food security, while generating water savings that make more water available for other productive uses. Beyond water savings, this paper also discusses the economic and social gains that double cropping produces for the public within a broader developmental context.

The transboundary nature of water resources demands a transboundary approach to their monitoring and management. However, transboundary water projects raise a challenging set of problems related to communication issues, and standardization of sampling, analysis and data management methods. This manual addresses those challenges and provides the information and guidance needed to perform the Navruz Project, a cooperative, transboundary, river monitoring project involving rivers and institutions in Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan facilitated by Sandia National Laboratories in the U.S. The Navruz Project focuses on waterborne radionuclides and metals because of their importance to public health and nuclear materials proliferation concerns in the region. This manual provides guidelines for participants on sample and data collection, field equipment operations and procedures, sample handling, laboratory analysis, and data management. Also included are descriptions of rivers, sampling sites and parameters on which data are collected. Data obtained in this project are shared among all participating countries and the public through an internet web site, and are available for use in further studies and in regional transboundary water resource management efforts. Overall, the project addresses three main goals: to help increase capabilities in Central Asian nations for sustainable water resources management; to provide a scientific basis for supporting nuclear transparency and non-proliferation in the region; and to help reduce the threat of conflict in Central Asia over water resources, proliferation concerns, or other factors.

Serious forest fires were observed over Siberia, particularly in the vast area between Lake Baikal and the Gulf of Ob, during the period of 18-27 July 2016 using Moderate Resolution Imaging Spectroradiometer (MODIS) data. The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite simultaneously detected a multitude of smoke aerosols surrounding the same area. Combing a Lagrangian Flexible Particle dispersion model (FLEXPART) executed using the Weather Research and Forecasting (WRF) model output, the transport of smoke aerosols and the quantification of impact of Russian forest fires on the Asia were investigated. From model simulations, two transport paths were determined for the smoke plumes from the Russian forest fires. The first path was directed southwestward from Russia to Central Asia and eventually Xinjiang Province of China, furthermore, the second path was directed southeastward through Mongolia to Northeast China. The FLEXPART-WRF model simulations also revealed that the smoke aerosol concentrations entering the Central Asia, Mongolia and Northern China were approximately 60-300 μg m-3, 40-250 μg m-3 and 5-140 μg m-3, respectively. Meanwhile, the aerosol particles from these forest fires have an impact on the air quality in Asia. With the arrival of smoke aerosols from the Russian forest fires, the near-surface PM10 concentrations over Altay, Hulunbuir and Harbin increased to 61, 146 and 42 μg m-3, respectively. In conclusion, smoke aerosols from Russian forest fires can variably influence the air quality over Central Asia, Mongolia and Northern China.

The incidence of dengue has grown dramatically in recent decades worldwide, especially in Southeast Asia and the Americas with substantial transmission in 2014-2015. Yet the mechanisms underlying the spatio-temporal circulation of dengue virus (DENV) serotypes at large geographical scales remain elusive. Here we investigate the co-circulation in Asia of DENV serotypes 1-3 from 1956 to 2015, using a statistical framework that jointly estimates migration history and quantifies potential predictors of viral spatial diffusion, including socio-economic, air transportation and maritime mobility data. We find that the spread of DENV-1, -2 and -3 lineages in Asia is significantly associated with air traffic. Our analyses suggest the network centrality of air traffic hubs such as Thailand and India contribute to seeding dengue epidemics, whilst China, Cambodia, Indonesia, and Singapore may establish viral diffusion links with multiple countries in Asia. Phylogeographic reconstructions help to explain how growing air transportation networks could influence the dynamics of DENV circulation.

Full Text Available Abstract Background The incidence rate of Nocardia keratitis is increasing, with new species identified thanks to molecular methods. We herein report a case of Nocardia transvalensis keratitis, illustrating this emerging pathology among travellers returning from Asia. Case presentation A 23-year-old man presented with a 10-week history of ocular pain, redness, and blurred vision in his right eye following a projectile foreign body impacting the cornea while motor biking in Thaïland. At presentation, a central epithelial defect with a central whitish stromal infiltrate associated with pinhead satellite infiltrates was observed. Identification with 16S rRNA PCR sequencing and microbiological culture of corneal scraping and revealed N. transvalensis as the causative organism. Treatment was initiated with intensive topical amikacin, oral ketoconazole and oral doxycycline. After a four-week treatment period, the corneal infiltrate decreased so that only a faint subepithelial opacity remained. Conclusion Nocardia organisms should be suspected as the causative agent of any case of keratitis in travelers returning from Asia. With appropriate therapy, Nocardia keratitis resolves, resulting in good visual outcome.

Tephra (volcanic ash) layers have the potential to synchronise disparate palaeoenvironmental archives on regional to hemispheric scales. Highly productive arc regions, like those in East Asia, offer a considerable number of widespread isochrons, but before records can be confidently correlated using these layers, a refined and integrated framework of these eruptive events is required. Here we present the first high-resolution Holocene cryptotephra study in East Asia, using the Lake Suigetsu sedimentary archive in central Japan. The Holocene tephrostratigraphy has been extended from four to twenty ash layers using cryptotephra extraction techniques, which integrates the deposits from explosive eruptions from North Korea/China, South Korea and along the Japanese arc. This Lake Suigetsu tephrostratigraphy is now the most comprehensive record of East Asian volcanism, and the linchpin site for correlating sequences across this region. Major element glass geochemical compositions are presented for the tephra layers in the sequence, which have been compared to proximal datasets to correlate them to their volcanic source and specific eruptions. This study has significantly extended the ash dispersal of many key Holocene marker layers, and has identified the first distal occurrence of isochrons from Ulleungdo and Changbaishan volcanoes. Utilising the high-precision Lake Suigetsu chronology, we are able to provide constrained eruption ages for the tephra layers, which can be transferred into other site-specific age models containing these markers. This new framework indicates that several isochrons stratigraphically bracket abrupt climate intervals in Japan, and could be used to precisely assess the regional and hemispheric synchronicity of these events.

THE FIELD OF RECENT TECTONIC STRESSES IN CENTRAL AND SOUTH-EASTERN ASIA

Full Text Available  The publication presents results of the study aimed at reconstruction of recent crustal stresses for Central and South-Eastern Asia with application of the method of cataclastic analysis of displacements caused by ruptures, which was proposed by Yu.L. Rebetsky. Two sources of seismic data were referred to: (1 the catalog comprising data from publications covering the period from 1904 to 1992, and (2 the Global Centroid Moment Tensor (CMT Database of earthquake mechanisms (http://earthquake.usgs.gov/eqarchives/sopor, which covers the period from 1978 to 2010. The method of cataclastic analysis in its earliest version was applied in 1996 and 1997 when seismic data from the first catalog were analyzed, and it yielded only parameters of stress ellipsoids; the reconstructions were published in a Russian-Chinese journal (it does not exist now. In this paper, these reconstructions are presented in new graphical formats of GIS. Data from the Global CMT Database were analyzed by the method of cataclastic analysis in the new revision with application of its stages 1 and 2. Based on the calculations, orientations of axes of principal stresses, types of ellipsoids, correlations between spherical and deviatoric components of stress tensors, and reduced stresses were determined. The two sets of reconstructions are compared in this paper. The catalog of earthquake focal mechanisms for the period from 1904 to 1992 consolidated information provided by different authors, and thus focal data for many seismic events were highly inconsistent; therefore, the reliability of reconstructions based on such data seems to be lower than that on the basis the Global CMT Database for the period from 1978 to 2010. Some of the reconstructed stress tensor parameters are mapped. For the areas which data are given in the Global CMT Database and considered as more reliable, mapping is based on stress parameters calculated from such data.

Various studies on ancient DNA have attempted to reconstruct population movement in Asia, with much interest focused on determining the arrival of European lineages in ancient East Asia. Here, we discuss our analysis of the mitochondrial DNA of human remains excavated from the Yu Hong tomb in Taiyuan, China, dated 1400 years ago. The burial style of this tomb is characteristic of Central Asia at that time. Our analysis shows that Yu Hong belonged to the haplogroup U5, one of the oldest western Eurasian-specific haplogroups, while his wife can be classified as haplogroup G, the type prevalent in East Asia. Our findings show that this man with European lineage arrived in Taiyuan approximately 1400 years ago, and most probably married a local woman. Haplogroup U5 was the first west Eurasian-specific lineage to be found in the central part of ancient China, and Taiyuan may be the easternmost location of the discovered remains of European lineage in ancient China.

The semi-arid regions of Central Asia crucially depend on the water resources supplied by the mountainous areas of the Tien Shan and Pamir and Altai mountains. During the summer months the snow-melt- and glacier-melt-dominated river discharge originating in the mountains provides the main water resource available for agricultural production, but also for storage in reservoirs for energy generation during the winter months. Thus a reliable seasonal forecast of the water resources is crucial for sustainable management and planning of water resources. In fact, seasonal forecasts are mandatory tasks of all national hydro-meteorological services in the region. In order to support the operational seasonal forecast procedures of hydro-meteorological services, this study aims to develop a generic tool for deriving statistical forecast models of seasonal river discharge based solely on observational records. The generic model structure is kept as simple as possible in order to be driven by meteorological and hydrological data readily available at the hydro-meteorological services, and to be applicable for all catchments in the region. As snow melt dominates summer runoff, the main meteorological predictors for the forecast models are monthly values of winter precipitation and temperature, satellite-based snow cover data, and antecedent discharge. This basic predictor set was further extended by multi-monthly means of the individual predictors, as well as composites of the predictors. Forecast models are derived based on these predictors as linear combinations of up to four predictors. A user-selectable number of the best models is extracted automatically by the developed model fitting algorithm, which includes a test for robustness by a leave-one-out cross-validation. Based on the cross-validation the predictive uncertainty was quantified for every prediction model. Forecasts of the mean seasonal discharge of the period April to September are derived every month from

Between May 2005 and March 2008 the CARIBIC observatory (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container) was deployed to make atmospheric observations during 21 round-trip flights between Frankfurt, Germany and Manila, the Philippines with a stopover in Guangzhou, China. This nearly 3 year flight series provides us with information about atmospheric composition in the free and upper troposphere over Asia during all seasons and was used to investigate seasonal and regional differences in trace gas distributions and the relative influences of long range transport and convected local air masses on composition. The flight route was separated into three different regions having unique characteristics in transport and composition; these were Western Asia (5°E to 70°E), Central Asia (70°E to 100°E) and East Asia (100°E to 125°E). The region over Western Asia was heavily influenced by long range transport of air masses from North America and had elevated levels of NOy and acetone, while the region over East Asia was mostly influenced by convected local (South East Asian) pollution, particularly from biomass/biofuel burning as indicated by high levels of acetonitrile and carbon monoxide. Air masses over Central Asia were found to be influenced by both recently convected air masses from the Indian subcontinent and mid-range transport from Eastern Europe and the Middle East. Elevated levels of propane and other non-methane hydrocarbons, both with and without concommitant elevations in other trace gases (i.e. carbon monoxide, acetonitrile) were a persisent feature of this region in all seasons except summer, and were particularly prominent in fall. Influences on composition over Central Asia were investigated more thoroughly in a case study from a series of flights in October 2006, and elevated levels of pollutants were found to be the result of convective transport of both biomass/biofuel burning and urban emissions from

Background Although the presence of Asia 2 group of canine distemper virus (CDV) was known by the sequencing and phylogenetic analysis of hemagglutinin (H) gene, the fusion (F) protein gene sequence of Asia 2 group had not been identified. So, the sequence analysis of F gene was carried out to elucidate the genotypic varaitons among Asian isolates. Results The phylogenetic analysis of F and H gene sequences from fourteen CDV isolates obtained from diseased dogs in Japan and Thailand indicated that the F genes had a new initiation codon and extra 27 nucleotides upstream of the usual open reading frame (ORF) and the F proteins had extra 9 amino acids at the N-terminal position only in Asia 2 isolates. On the contrary, the Asia 1 isolates had three extra putative N-glycosylation sites (two sites in the signal peptide region and one site in the F1 region) except for two strains of Th12 and Ac96I (two sites in signal peptide region) adding to four putative N-glycosylation sites that were conserved among all Asian isolates and Onderstepoort strain. In addition to this difference in N-glycosylation sites, the signal peptide region had a great diversity between Asia 1 and Asia 2 isolates. Also, characteristic amino acids were detected for some strains. Conclusion Asia 2 isolates were distinguished from other CDV lineages by the extra 27 nucleotide sequence. The signal peptide region of F gene gives a remarkable differentiation between Asia 1 and Asia 2 isolates. Strains Th12 and Ac96I were differentiated from other Asia 1 strains by the F protein glycosylation sites. PMID:19807927

The semi-arid regions of Central Asia crucially depend on the water resources supplied by the mountainous areas of the Tien-Shan and Pamirs. During the summer months the snow and glacier melt water of the rivers originating in the mountains provides the only water resource available for agricultural production but also for water collection in reservoirs for energy production in winter months. Thus a reliable seasonal forecast of the water resources is crucial for a sustainable management and planning of water resources.. In fact, seasonal forecasts are mandatory tasks of national hydro-meteorological services in the region. Thus this study aims at a statistical forecast of the seasonal water availability, whereas the focus is put on the usage of freely available data in order to facilitate an operational use without data access limitations. The study takes the Naryn basin as a test case, at which outlet the Toktogul reservoir stores the discharge of the Naryn River. As most of the water originates form snow and glacier melt, a statistical forecast model should use data sets that can serve as proxy data for the snow masses and snow water equivalent in late spring, which essentially determines the bulk of the seasonal discharge. CRU climate data describing the precipitation and temperature in the basin during winter and spring was used as base information, which was complemented by MODIS snow cover data processed through ModSnow tool, discharge during the spring and also GRACE gravimetry anomalies. For the construction of linear forecast models monthly as well as multi-monthly means over the period January to April were used to predict the seasonal mean discharge of May-September at the station Uchterek. An automatic model selection was performed in multiple steps, whereas the best models were selected according to several performance measures and their robustness in a leave-one-out cross validation. It could be shown that the seasonal discharge can be predicted with

Arid central Asia (ACA) is one of the largest arid (desert) areas in the world, and its climate is dominated by the westerlies. In this study, we examined sand dune evolution from the Bayanbulak Basin in the Tian Shan (Xinjiang, NW China), aiming to infer the Holocene moisture history of the ACA. Combined with stratigraphic observation and environmental proxies analysis (grain size, magnetic susceptibility and total organic content), large numbers of luminescence ages from multiple sites (eight sections, 79 samples) were applied to reconstruct the evolution of the sand dune accumulation in the study basin. The overall results imply very dry conditions characterized by sand dune accumulation at ∼12-6.5 ka, a wet interval between ∼6.5 and 0.8 ka when soil formation occurred, and decreased moisture during the last 0.8 ka. This moisture variation pattern is generally consistent with that inferred from many lacustrine records in the core zone of ACA, suggesting a widespread dry period in the early-to-middle Holocene and relatively wet middle-to-late Holocene. Thus, the moisture history derived from the current sand dune system contrasts with that in Asian monsoon areas, which are characterized by a strong monsoon (high precipitation) in the early and mid-Holocene and a weak monsoon (low precipitation and dry climate) during the late Holocene. Our results strongly suggest that the winter solar insolation and the external boundary conditions such as atmospheric CO2 concentration, ice sheets, and meltwater fluxes, have been major influential factors triggering the Holocene moisture evolution in the core zone of ACA.

Chikungunya virus (CHIKV) is transmitted by Aedes aegypti and Aedes albopictus mosquitoes and causes febrile illness with severe arthralgia in humans. There are 3 circulating CHIKV genotypes, Asia, East/Central/South Africa, and West Africa. CHIKV was first reported in 1953 in Tanzania, and up until the early 2000s, a few outbreaks and sporadic cases of CHIKV were mainly reported in Africa and Asia. However, from 2004 to 2005, a large epidemic spanned from Kenya over to the southwestern Indian Ocean region, India, and Southeast Asia. Identified in 2005, the E1 glycoprotein A226V mutation of the East/Central/South Africa genotype conferred enhanced transmission by the A. albopictus mosquito and has been implicated in CHIKV's further spread in the last decade. In 2013, the Asian CHIKV genotype emerged in the Caribbean and quickly took the Americas by storm. This review will discuss the history of CHIKV as well as its expanding geographic distribution. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

Challenges in the Energy Sector in Eastern Europe and Central Asia: An Evaluation of 18 Years of Swiss Economic Cooperation

Directory of Open Access Journals (Sweden)

Guy Bonvin

2011-05-01

Full Text Available Published by Palgrave MacmillanSwitzerland’s State Secretariat for Economic Affairs (SECO has been working in the energy sectors of Eastern Europe and Central Asia since 1992, financing 41 projects to the value of CHF 316 million. In 2009 an independent evaluation was commissioned to assess the effects of these projects in the region and to draw lessons for future project funding. The evaluation found the projects to be highly satisfactory in terms of relevance, satisfactory in terms of effectiveness and sustainability, and — because of external factors relating to governance, transparency and political stability in a country — generally unsatisfactory in terms of efficiency.Lessons drawn from the successful projects will be used to further improve them in the future. With limited financial resources governments are attempting to find a balance between energy security and environmental sustainability. SECO will support this mission by helping to reduce inefficient consumption, to increase the share of renewable energy, to strengthen the sustainability of utility companies and to develop effective energy policies.

Full Text Available No economies throughout the region managed to escape from the "global economic crisis in 2008" that was initiated in the United States. This is a logical consequence of the global economy that has been rolling along. The world economy is increasingly becoming more integrated and interdependent with one another. Exposure stems from the economic crisis in the prolonged United States subprime mortgage financial crisis, and eventually dragged the European economy, and also Asia. The Asian region was only affected, but even if only the impact of course, was enough to overwhelm the Asian region since the crisis has a major impact on a country's foreign exchange reserves. Therefore, after the G-20 summit held in Washington on November 15, 2008, the three major Asian countries, namely China, Japan and South Korea held a summit in Fukuoka Japanese initiative, which was attended by the three heads of government. This summit was to bring fresh air for the Asian region, because in addition to having a positive impact on Asian stocks, it also provides a new self confidence that Asia has formed an alliance that would at least fortify themselves (region with the resulting stimulus policy. This initiative to find a solution is eventually expanded, and was welcomed by ASEAN countries, known as ASEAN Plus Three. Since in Asia there is already the East Asia Summit (East Asia Summit, the negotiations and the name of the group changed into the 6 partner countries of ASEAN. These six countries are Japan, China, South Korea, Australia, New Zealand, and India.

2017-01-01

The socioeconomic difficulties of southwest Asia, defined as the area bound by the domain 25°N–40°N and 40°E–70°E, are exacerbated by extreme precipitation deficits during the November–April rainy season. The precipitation deficits during many southwest Asia droughts have been examined in terms of the forcing by climate variability originating over the Pacific Ocean as a result of the El Niño–Southern Oscillation (ENSO), Pacific decadal variability (PDV), and the long-term warming of Pacific (LT) sea surface temperatures (SST). Here we examine how the most extreme November–April southwest Asia droughts relate to global SSTs and the associated large-scale atmospheric circulation anomalies and analyze the specific atmospheric forcing mechanisms responsible for changes in regional southwest Asian precipitation. The driest November–April seasons during 1948–2012 over southwest Asia are forced by subsidence and reductions of moisture fluxes as a result of the interaction of the mean flow with anomalous zonally symmetric high pressure throughout the Northern Hemisphere. The anomalous zonally symmetric high pressure throughout the Northern Hemisphere occurs simultaneously with cool central and eastern Pacific SST anomalies associated with La Niña and the negative phase of PDV and a warm west Pacific Ocean caused in part by the long-term warming of the west Pacific Ocean.

The luminescence dating chronology of a deep core from Bosten Lake (NW China) in arid central Asia reveals lake evolution over the last 220 ka

2016-01-01

The lacustrine deposits of lakes in arid central Asia (ACA) potentially record palaeoclimatic changes on orbital and suborbital time scales, but such changes are still poorly understood due to the lack of reliable chronologies. Bosten Lake, the largest freshwater inland lake in China, is located...... in the southern Tianshan Mountains in central ACA. A 51.6-m-deep lacustrine succession was retrieved from the lake and 30 samples from the succession were used for luminescence dating to establish a chronology based on multi-grain quartz OSL and K-feldspar post-IR IRSL (pIRIR290) dating. Quartz OSL ages were only....... A stable deep lake occurred at c. 220, 210–180, c. 165, 70–60, 40–30 and 20–5 ka, while shallow levels occurred at c. 215, 180–165, 100–70, 60–40 and 30–20 ka. Bosten Lake levels decreased by at least ~29 m and possibly the lake even dried up between c. 160 and c. 100 ka. We suggest that the water...

Asia-Pacific lube oil markets

Yamaguchi, N.

2001-01-01

An overview of the Asia-Pacific (AP) lubricating oils market, its special characteristics, and its role in the global economy are presented. In the 'boom and bust' years of 1997-1999, the Asia-Pacific market was even bigger then the US market. For the short-term, the scenario is surplus capacity and poor margins, but in the long term there is enormous potential for growth. How fuel demand and quality is related to engine type is discussed. The three basic grades of baseoils are described, and the Asia-Pacific lube demand and the Asia-Pacific lube oil supply are discussed. There are 15 diagrams giving data on: (i) finished lubes in world markets as a percentage of total; (ii) how lube demand follows GDP per capita in Asia; (iii) AP baseoil capacity relationships; (iv) AP baseoil disposition by end use; (v) AP changing shares of baseoil demand; (vi) AP finished lube demand by subregion; (vii) AP finished lube demand growth, indexed; (viii) AP baseoil capacity by region; Singapore baseoil vs. Dubai crude prices, 1992-99; (ix) Singapore baseoil vs. crude prices, 1992-99; (x) AP baseoil deficit moved to surplus; (xi) AP baseoil production; (xii) East Asia net percentage change in lube sales, 1997-1999. (xiii) Southeast Asia net percentage change in lube sales, 1997-1999; (xiv) South East Asia and Australia net percentage change in lube sales, 1997-1999 and (xv) Asia-Pacific major lube marketers

Responses of ecosystem assimilation and respiration to global climate change vary considerably among terrestrial ecosystems constrained by both biotic and abiotic factors. In this study, net CO 2 exchange between ecosystem and atmosphere (NEE) was measured over a 4-year period (2013-2016) using eddy covariance technology in a desert ecosystem in Central Asia. Ecosystem assimilation (gross primary production, GPP) and respiration (R eco ) were derived from NEE by fitting light response curves to NEE data based on day- and nighttime data, and their responses to soil water content (SWC) and evaporative fraction (EF) were assessed during the growing season. Results indicated that both GPP and R eco linearly decreased with declining SWC, with the sensitivity of GPP to SWC being 3.8 times higher than that of R eco during the entire growing season. As a result, ecosystem CO 2 sequestration capacity decreased from 4.00μmolm -2 s -1 to 1.00μmolm -2 s -1 , with increasing soil drought . On a seasonal scale, significant correlation between GPP and SWC was only found in spring while that between R eco and SWC was found in all growing seasons with the sensitivity increasing steadily from spring to autumn. EF had a low correlation with SWC, GPP and R eco (R 2 =0.03, 0.02, 0.05, respectively), indicating that EF was not a good proxy for soil drought and energy partitioning was not tightly coupled to ecosystem carbon exchanges in this desert ecosystem. The study deepens our knowledge of ecosystem carbon exchange and its response to drought as well as its coupling with ecosystem energy partitioning in an extreme dry desert. The information is critical for better assessing carbon sequestration capacity in dryland, and for understanding its feedback to climate change. Copyright © 2017 Elsevier B.V. All rights reserved.

Globalization of the cashmere market and the decline of large mammals in central Asia.

Science.gov (United States)

Berger, Joel; Buuveibaatar, Bayarbaatar; Mishra, Charudutt

2013-08-01

As drivers of terrestrial ecosystems, humans have replaced large carnivores in most areas, and human influence not only exerts striking ecological pressures on biodiversity at local scales but also has indirect effects in distant corners of the world. We suggest that the multibillion dollar cashmere industry creates economic motivations that link western fashion preferences for cashmere to land use in Central Asia. This penchant for stylish clothing, in turn, encourages herders to increase livestock production which affects persistence of over 6 endangered large mammals in these remote, arid ecosystems. We hypothesized that global trade in cashmere has strong negative effects on native large mammals of deserts and grassland where cashmere-producing goats are raised. We used time series data, ecological snapshots of the biomass of native and domestic ungulates, and ecologically and behaviorally based fieldwork to test our hypothesis. In Mongolia increases in domestic goat production were associated with a 3-fold increase in local profits for herders coexisting with endangered saiga (Saiga tatarica).That increasing domestic grazing pressure carries fitness consequences was inferred on the basis of an approximately 4-fold difference in juvenile recruitment among blue sheep (Pseudois nayaur)in trans-Himalayan India. Across 7 study areas in Mongolia, India, and China's Tibetan Plateau, native ungulate biomass is now degradation and decreased capacity for the persistence of native species, including at least 8 Asian endemic species: saiga, chiru (Pantholops hodgsoni), Bactrian camel (Camelus bactrianus), snow leopard(Panthera uncia), khulan(Equus hemionus), kiang (E. kiang), takhi (E. przewalski), and wild yak (Bos mutus). Our results suggest striking yet indirect and unintended actions that link trophic-level effects to markets induced by the trade for cashmere. © 2013 Society for Conservation Biology.

Modeling the epidemiological history of plague in Central Asia: Palaeoclimatic forcing on a disease system over the past millennium

Directory of Open Access Journals (Sweden)

Kausrud Kyrre

2010-08-01

Full Text Available Abstract Background Human cases of plague (Yersinia pestis infection originate, ultimately, in the bacterium's wildlife host populations. The epidemiological dynamics of the wildlife reservoir therefore determine the abundance, distribution and evolution of the pathogen, which in turn shape the frequency, distribution and virulence of human cases. Earlier studies have shown clear evidence of climatic forcing on contemporary plague abundance in rodents and humans. Results We find that high-resolution palaeoclimatic indices correlate with plague prevalence and population density in a major plague host species, the great gerbil (Rhombomys opimus, over 1949-1995. Climate-driven models trained on these data predict independent data on human plague cases in early 20th-century Kazakhstan from 1904-1948, suggesting a consistent impact of climate on large-scale wildlife reservoir dynamics influencing human epidemics. Extending the models further back in time, we also find correspondence between their predictions and qualitative records of plague epidemics over the past 1500 years. Conclusions Central Asian climate fluctuations appear to have had significant influences on regional human plague frequency in the first part of the 20th century, and probably over the past 1500 years. This first attempt at ecoepidemiological reconstruction of historical disease activity may shed some light on how long-term plague epidemiology interacts with human activity. As plague activity in Central Asia seems to have followed climate fluctuations over the past centuries, we may expect global warming to have an impact upon future plague epidemiology, probably sustaining or increasing plague activity in the region, at least in the rodent reservoirs, in the coming decades.

Full Text Available The article deals with the combat of forced labor and human trafficking in Central Asia. It is noted that this problem has emerged since the early 90s, when these countries got the independence, due to the difficult economic situation, activity of extremist organizations. It is pointed out that the victims of trafficking may be men, women and children, but in most cases they are young women and girls who are sexually exploited. It is shown by the examples of each of the countries of the region, what is being done to counter this terrible phenomenon. The Government of the Republic of Tajikistan established the Interdepartmental Commission to Combat Human Trafficking. The commission, in cooperation with international organizations doing some work to inform the public, the search for victims of sexual business, return and rehabilitation of these persons. In Kazakhstan, according to the new law it has become easier to initiate criminal proceedings concerning labor slavery. In addition, a temporary accommodation center for victims of human trafficking «Komek» was created. In Kyrgyzstan, a working group on the development of 3 of the National Action Plan to Combat Trafficking in Human Beings (2011-2015 under the auspices of the Ministry of Labour, Employment and Migration of the Kyrgyz Republic was created. In Uzbekistan, the law «on combating human trafficking» came into force. In addition, a Republican Interdepartmental Commission to Combat Human Trafficking was created. The law defines the powers of public authorities directly involved in the activities in this direction. In Turkmenistan, the government prohibits all forms of trafficking of persons in accordance with Article 129 of the Criminal Code, adopted in May 2010 and entered into force in July 2010. It provides for penalties ranging from 4 to 25 years in prison. These penalties sufficiently stringent and commensurate with penalties prescribed for other serious crimes, such as rape. At

Energy security, trans-national pipelines and China's role in Asia

International Nuclear Information System (INIS)

Seaman, J.

2010-01-01

In recent decades, China's transformation from a regional energy supplier to one of the world's largest net energy importers, in particular with regards to oil and gas, has led to an increasing sense of energy insecurity in Chinese policy circles. Guaranteeing adequate supplies of energy to fuel economic growth is a central element in Beijing's efforts to maintain legitimacy in the face of economic reform and transformation. To combat energy insecurity a number of initiatives are being undertaken to diversify energy inputs, suppliers, and the means of their transport. Among these initiatives are a series of trans-national pipeline projects that will transport oil and gas from Eastern Siberia, Central Asia, and Southeast Asia, effectively reducing China's overall reliance on international sea lanes and maritime choke-points, in particular the Strait of Malacca. An analysis of these projects can shed light on how China's energy security policies are playing out on a regional level, how they are complicated and aided by various competing and converging interests of regional actors, and how they are re-shaping traditional regional dependencies. Indeed, more complex interdependencies among suppliers, consumers and transit states in continental Asia seem to be emerging as a consequence of China's growing role as an energy consumer. In the end, these pipelines help to diversify China's oil and gas suppliers and transport routes, easing its reliance on Middle Eastern oil and maritime transit, but they are by no means an alternative to the latter. China will continue to rely heavily on international oil markets and maritime shipping routes to deliver Middle Eastern oil. Suring up international markets and finding means to cooperate on international maritime security issues are thus and will remain in China's best interest. (author)

Desert beetle Microdera punctipennis (Coleoptera: Tenebriondae) is a special species in Gurbantonggut Desert in Central Asia. To investigate the possible strategy it employs for cold survival, seasonal changes in supercooling point (SCP), body water content, haemolymph osmolality and antifreeze protein gene (Mpafp) expression were measured over 13 months. Our results show SCPs in M. punctipennis adults changed from -8.0°C in summer to -18.7°C in winter. During winter, adults endured modest water loss; total water decreased from 65.4 percent in summer to 55.9% in winter. Mpafp mRNAs level increased by 13.1 fold from summer to early winter, and haemolymph osmolality increased accordingly from 550 mOsm to 1486 mOsm. Correlation coefficient of Mpafp mRNAs level and SCP indicates that Mpafp mRNA explained 65.3 percent of the variation in SCPs. The correlation between Mpafp mRNA level and total water reflected an indirect influence of antifreeze protein on water content via reducing SCP.

pressure and that in the high-T rocks was featured by the significant increase of temperature. The pressure increase could attribute to the progressive crustal thickening that may be correlated to the accretionary regime of the southern Altai in the mid-Devonian and the high temperature conditions most likely imply a significant heat input from the deep depth, consistent with the syn-chronologically emplacement of juvenile magmas on a large scale. Our study indicates the development of high-T metamorphism was genetically linked with that of the medium-P metamorphism and suggests that the crustal thickening during the orogenic process of the Altai region was accompanied by large heat input.

Climate models currently provide conflicting predictions of future climate change across Central Asia. With concern over the potential for a change in water availability to impact communities and ecosystems across the region, an understanding of historical trends in precipitation is required to aid model development and assess the vulnerability of the region to future changes in the hydroclimate. Here we present a record from Lake Baikal, located in the southern Siberian region of central Asia close to the Mongolian border, which demonstrates a relationship between the oxygen isotope composition of diatom silica (δ18Odiatom) and precipitation to the region over the 20th and 21st Century. From this, we suggest that annual rates of precipitation in recent times are at their lowest for the past 10,000 years and identify significant long-term variations in precipitation throughout the early to late Holocene interval. Based on comparisons to other regional records, these trends are suggested to reflect conditions across the wider Central Asian region around Lake Baikal and highlight the potential for further changes in precipitation with future climate change.

Rainfall-runoff relationship is the most important factor for hydrological structures, social and economic development on the background of global warmer, especially in arid regions. The aim of this paper is find the suitable method to simulate the runoff in arid area. The Soil Conservation Service Curve Number (SCS-CN) is the most popular and widely applied model for direct runoff estimation. In this paper, we will focus on Wen-quan Basin in source regions of Boertala River. It is a typical valley of inland in Central Asia. First time to use the 16m resolution remote sensing image about high-definition earth observation satellite “Gaofen-1” to provide a high degree accuracy data for land use classification determine the curve number. Use surface temperature/vegetation index (TS/VI) construct 2D scatter plot combine with the soil moisture absorption balance principle calculate the moisture-holding capacity of soil. Using original and parameter algorithm improved SCS-CN model respectively to simulation the runoff. The simulation results show that the improved model is better than original model. Both of them in calibration and validation periods Nash-Sutcliffe efficiency were 0.79, 0.71 and 0.66,038. And relative error were3%, 12% and 17%, 27%. It shows that the simulation accuracy should be further improved and using remote sensing information technology to improve the basic geographic data for the hydrological model has the following advantages: 1) Remote sensing data having a planar characteristic, comprehensive and representative. 2) To get around the bottleneck about lack of data, provide reference to simulation the runoff in similar basin conditions and data-lacking regions.

Lithospheric controls on crustal reactivation and intraplate mountain building in the Gobi Corridor, Central Asia

Cunningham, D.

2017-12-01

This talk will review the Permian-Recent tectonic history of the Gobi Corridor region which includes the actively deforming Gobi Altai-Altai, Eastern Tien Shan, Beishan and North Tibetan foreland. Since terrane amalgamation in the Permian, Gobi Corridor crust has been repeatedly reactivated by Triassic-Jurassic contraction/transpression, Late Cretaceous extension and Late Cenozoic transpression. The tectonic history of the region suggests the following basic principle for intraplate continental regions: non-cratonized continental interior terrane collages are susceptible to repeated intraplate reactivation events, driven by either post-orogenic collapse and/or compressional stresses derived from distant plate boundary convergence. Thus, important related questions are: 1) what lithospheric pre-conditions favor intraplate crustal reactivation in the Gobi Corridor (simple answer: crustal thinning, thermal weakening, strong buttressing cratons), 2) what are the controls on the kinematics of deformation and style of mountain building in the Gobi-Altai-Altai, Beishan and North Tibetan margin (simple answer: many factors, but especially angular relationship between SHmax and `crustal grain'), 3) how does knowledge of the array of Quaternary faults and the historical earthquake record influence our understanding of modern earthquake hazards in continental intraplate regions (answer: extrapolation of derived fault slip rates and recurrence interval determinations are problematic), 4) what important lessons can we learn from the Mesozoic-Cenozoic tectonic history of Central Asia that is applicable to the tectonic evolution of all intraplate continental regions (simple answer: ancient intraplate deformation events may be subtly expressed in the rock record and only revealed by low-temperature thermochronometers, preserved orogen-derived sedimentary sequences, fault zone evidence for younger brittle reactivation, and recognition of a younger class of cross-cutting tectonic

Water Related Health Problems in Central Asia—A Review

Directory of Open Access Journals (Sweden)

Zakir Bekturganov

2016-05-01

Full Text Available The present paper provides an extensive literature review on water related health issues in Central Asia. Even though the per capita amount of available freshwater is substantial in all Central Asian states the uneven distribution in time and space creates problems for water availability. Due to this, the Central Asian economies are developing under increasing water deficiency. The degradation of water supply systems and sewage treatment plants is often severe leading to potentially high water loss rates and inadequate accessibility to safe water supply. In this context, rural areas are the most affected. Low tariffs in combination with absent metering and low collection rates for water fees mean that operation and maintenance costs for basic services of water supply and sanitation are not covered. Unsafe water supply contains both microbiological and non-microbiological contaminants. Helminthiasis and intestinal protozoa infections are of considerable public health importance in Central Asia. Agricultural and industrial pollution is especially affecting downstream areas of Amu Darya and Syr Darya rivers. In large areas copper, zinc, and chromium concentrations in water exceed maximum permissible concentration. Thus, there is an urgent need to strengthen the environmental monitoring system. Small-scale water supply and sanitation systems need to be developed in line with more efficient public spending on these.

MEEREB is an informal network of rabies experts from the Middle East, Eastern Europe and Central Asia, seeking to eliminate rabies from the region. They met for the second time to review the current rabies situation, both globally and in their respective countries, highlighting current rabies control problems and potential solutions. Success stories in Latin America, in Western Europe, in some Asian countries, as well as in Croatia and Serbia prove that elimination of human rabies is achievable in the MEEREB region. It requires political willingness and cooperation of all stakeholders, including Ministries of Health and of Agriculture; adequate management of animal bites through post-exposure prophylaxis; pre-exposure prophylaxis for populations at high risk of rabies exposure, animal vaccination and humane control of stray dog populations. MEEREB members called for a regional initiative for rabies elimination in Eastern Europe and the Middle East. They are confident that the elimination of human rabies of canine origin can be achieved in the region through adopting a One Health approach, and that campaigns for rabies elimination will have significant benefit for public health, including strengthening the structure for control of other zoonoses. © 2013 Blackwell Verlag GmbH.

Coherent changes of wintertime surface air temperatures over North Asia and North America.

Science.gov (United States)

Yu, Bin; Lin, Hai

2018-03-29

The surface temperature variance and its potential change with global warming are most prominent in winter over Northern Hemisphere mid-high latitudes. Consistent wintertime surface temperature variability has been observed over large areas in Eurasia and North America on a broad range of time scales. However, it remains a challenge to quantify where and how the coherent change of temperature anomalies occur over the two continents. Here we demonstrate the coherent change of wintertime surface temperature anomalies over North Asia and the central-eastern parts of North America for the period from 1951 to 2015. This is supported by the results from the empirical orthogonal function analysis of surface temperature and temperature trend anomalies over the Northern Hemisphere extratropical lands and the timeseries analysis of the regional averaged temperature anomalies over North Asia and the Great Plains and Great Lakes. The Asian-Bering-North American (ABNA) teleconnection provides a pathway to connect the regional temperature anomalies over the two continents. The ABNA is also responsible for the decadal variation of the temperature relationship between North Asia and North America.

Alternatives of Cross-Border Securities Settlement System in East Asia

Directory of Open Access Journals (Sweden)

Hee-Yul Chai

2005-12-01

Full Text Available The establishment of cross-border securities settlement system is a very important element of regional capital market integration. Despite its importance, relatively few arguments, both theoretical and practical, have been advanced on the subject. This paper aims to examine the alternatives of cross-border securities settlement system in East Asia, and analyse the feasibility and the advantages and disadvantages of each alternative. The paper underlines the need to develop a multi-currency DVP securities settlement system. The conceivable alternatives of East Asia's cross-border securities settlement system can be divided into decentralized system and centralized system. It is possible to consider a large array of institutional settings according to the depository/settlement methods. The comparison of the alternatives is based on economic efficiency, feasibility and institutional location of settlement system. In view of these criteria, it is argued that a 'big-bang' approach toward imperfectly cenralized system is the most desirable alternative.

It is characterized by: 21 total vertebrae; very slender and long first dorsal spine with tiny anterior barbs; thin and lancet-shaped basal pterygiophore of the spiny dorsal fin, with its ventral margin separated from the skull; proximal tip of moderately slender first pterygiophore of the soft dorsal fin not reaching far ventrally; soft dorsal-fin base longer than anal-fin base; caudal peduncle having nearly equal depth and length; and tiny, fine scales with slender, straight spinules. The occurrence of this fossil filefish from the Bessho Formation is consistent with the influence of warm water currents suggested by other fossils, but it is inconsistent with the deep-water sedimentary environment of this Formation. This is the first fossil occurrence of a filefish in Asia; previously described fossil filefishes are known from the Pliocene and Pleistocene of Italy, the Pliocene of Greece, and the Miocene and Pliocene of North America. These fossil records suggest that the genus Aluterus had already been derived and was widely distributed during the Middle Miocene with taxa closely resembling Recent species.

Full Text Available Arid grassland ecosystems are widely distributed across Central Asia. However, there is a lack of research and observations of the land–atmosphere exchange of water and heat in the arid grasslands in this region, particularly over complex surfaces. In this study, systematic observations were conducted from 2013 to 2015 using an HL20 Bowen ratio and TDR300 and WatchDog1400 systems to determine the characteristics of these processes during the growing season (April–October of the arid mountainous grasslands of this region. (1 The latent heat flux (Le was lower than the sensible heat flux (He overall, and a small transient decrease in Le was observed before its daytime maximum; daily comparative variations in both fluxes were closely related to vegetation growth. (2 Evapotranspiration (ET showed substantial variation across different years, seasons and months, and monthly variations in ET were closely related to vegetation growth. Water condensation (Q was low and relatively stable. Relatively high levels of soil water were measured in spring followed by a decreasing trend. The land–atmosphere exchange of water and heat during the growing season in this region was closely associated with phenology, available precipitation and terrain. This study provides data support for the scientific management of arid mountainous grasslands.

The phylogeography of Indoplanorbis exustus (Gastropoda: Planorbidae in Asia

Directory of Open Access Journals (Sweden)

Diaz Jose L

2010-07-01

Full Text Available Abstract Background The freshwater snail Indoplanorbis exustus is found across India, Southeast Asia, central Asia (Afghanistan, Arabia and Africa. Indoplanorbis is of economic importance in that it is responsible for the transmission of several species of the genus Schistosoma which infect cattle and cause reduced livestock productivity. The snail is also of medical importance as a source of cercarial dermatitis among rural workers, particularly in India. In spite of its long history and wide geographical range, it is thought that Indoplanorbis includes only a single species. The aims of the present study were to date the radiation of Indoplanorbis across Asia so that the factors involved in its dispersal in the region could be tested, to reveal potential historical biogeographical events shaping the phylogeny of the snail, and to look for signs that I. exustus might be polyphyletic. Results The results indicated a radiation beginning in the late Miocene with a divergence of an ancestral bulinine lineage into Assam and peninsular India clades. A Southeast Asian clade diverged from the peninsular India clade late-Pliocene; this clade then radiated at a much more rapid pace to colonize all of the sampled range of Indoplanorbis in the mid-Pleistocene. Conclusions The phylogenetic depth of divergences between the Indian clades and Southeast Asian clades, together with habitat and parasitological differences suggest that I. exustus may comprise more than one species. The timescale estimated for the radiation suggests that the dispersal to Arabia and to Southeast Asia was facilitated by palaeogeographical events and climate change, and did not require human involvement. Further samples from Afghanistan, Africa and western India are required to refine the phylogeographical hypothesis and to include the African Recent dispersal.

Projected Changes in the Annual Cycle of Precipitation over Central Asia by CMIP5 Models

Future changes in the annual cycle of the precipitation in central Asia (CA) were estimated based on the historical and Representative Concentration Pathway 8.5 (RCP8.5) experiments from 25 models of the Coupled Model Intercomparison Project phase 5 (CMIP5). Compared with the Global Precipitation Climatology Project (GPCP) observations, the historical (1979-1999) experiments showed that most models can capture the migration of rainfall centers, but remarkable discrepancies exist in the location and intensity of rainfall centers between simulations and observations. Considering the skill scores of precipitation and pattern correlations of circulations, which are closely related to the precipitation for each month, for the 25 models, the four best models (e.g., CanESM2, CMCC-CMS, MIROC5 and MPI-ESM-LR) with relatively good performance were selected. The four models' ensemble mean indicated that the migration and location of the precipitation centers were better reproduced, except the intensity of the centers was overestimated, compared with the result that only considered precipitation. Based on the four best models' ensemble mean under RCP8.5 scenarios, precipitation was projected to increase dramatically over most of the CA region in the boreal cold seasons (November, December, January, February, March, April and May) with the maximum in December in the end of twenty-first century (2079-2099), and several positive centers were located in the Pamirs Plateau and the Tianshan Mountains. By contrast, the precipitation changes were weak in the boreal warm seasons (June, July, August, September and October), with a wet center located in the northern Himalayas. Furthermore, there remain some uncertainties in the projected precipitation regions and periods obtained by comparing models' ensemble results of this paper and the results of previous studies. These uncertainties should be investigated in future work.

Gastric cancer (GC) is the fourth most common cancer in the world with more than 70% of cases occur in the developing world. More than 50% of cases occur in Eastern Asia. GC is the second leading cause of cancer death in both sexes worldwide. In Asia, GC is the third most common cancer after breast and lung and is the second most common cause of cancer death after lung cancer. Although the incidence and mortality rates are slowly declining in many countries of Asia, GC still remains a significant public health problem. The incidence and mortality varies according to the geographic area in Asia. These variations are closely related to the prevalence of GC risk factors; especially Helicobacter pylori (H. pylori) and its molecular virulent characteristics. The gradual and consistent improvements in socioeconomic conditions in Asia have lowered the H. pylori seroprevalence rates leading to a reduction in the GC incidence. However, GC remains a significant public health and an economic burden in Asia. There has been no recent systemic review of GC incidence, mortality, and H. pylori molecular epidemiology in Asia. The aim of this report is to review the GC incidence, mortality, and linkage to H. pylori in Asia.

Asia electricity study

Electricity demand in Asia has grown and continues to grow rapidly. Over 40 per cent of the world's growth in electricity output up to 2010 is expected to come from China and East and South Asia. The need to build the additional production capacity to meet demand is the driving force behind the major structural and institutional changes that are presently transforming the electricity sectors throughout the region. The Asia Electricity Study looks in detail at the current and future role of the electricity sectors in Indonesia, the Philippines and Thailand. It analyses existing and planned electricity policies in areas such as financing regulation, environment and end-use efficiency. To build the region's power infrastructure will require large investments, well beyond what governments or multilateral lending institutions can provide. Consequently, mobilizing private sector participation in the process is vital. Independent Power Producers (IPPs) are being allowed to enter what has, until recently, been a government-dominated field. State-owned utilities are being corporatized and/or privatized to improve their competitiveness. Developing the regulatory environment to match the changes taking place is a key challenge. The significant expansion of generation capacity in Asia will have implications well beyond the region. Changes in energy trade volumes and patterns, caused by the need to obtain fuel for power stations, will have an impact on the energy security of Asia and the world as a whole Similarly, fuel and technology choices will have important consequences for both the regional and global environment.

Asia bears more than half the global tuberculosis (TB) burden. Economic development in the region has increased available funding for biomedical research and opportunity for collaboration. We explored the extent of international tuberculosis research collaborations between institutions within Asia. We conducted a Pubmed search for all articles with tuberculosis in the title published during a 12 month period with at least one author affiliation listed in Asia, then identified international collaborations from institution websites and internet searches. We identified 99 international collaborations involving an institution within Asia, of which only 8 (8.1%) were collaborations between Asian institutions. The remainder were with institutions outside of Asia. The paucity of intra-Asian international research collaboration represents a lost opportunity to optimise regional research funding, capacity building and the development of an Asia-relevant TB research agenda.

Regional Air Pollutions in Three Different Regions of Asia From a Transcontinental Transport Perspective

Asia is known as one of the regions with the fastest rate of growing in industrialization and urbanization. As a result, the rapid increases of large-scale air pollution in Asia emerge as a serious concern at both domestic and international levels. Apart from the problems of air quality degradation, emission control, environmental risk, and health effect in a domestic level, evidences from scientific studies indicate that by the long-range transport, Asian air pollution is becoming a global problem. Observations and model studies confirm that air pollution from Asia could be transported to North America or farther. In this work, we investigate the Asian air pollutions, in particular ozone and some other atmospheric components such as carbon monoxide and black carbon, from the ground- based observations in the three different regions, namely 1) background region of Siberia and central Asia, 2) highly anthropogenic region in eastern China, and 3) the rim region of the Asia-Pacific. In a transcontinental transport perspective, these regions are regarded as the inflow region, source region, and outflow region of Asia, respectively. From the results, it is found that the influences from large-scale emission in East Asia are observed clearly in the source region, and to the significant extent in the outflow region. For the inflow region of Asia, our data in Siberia and Kyrgyzstan indicate that air masses in this region are mostly intact from large-scale anthropogenic emission, and remain much of the global background atmospheric pollution characteristic. When the air masses are transported to source region, the air pollutants level increased sharply and frequent episodes of extremely high pollutions have been observed. Our results show good correlation between the residence time of air masses over the source region in eastern China and the observed levels of air pollutants verifying the strong enhancements by anthropogenic emissions from industrialization and

Full Text Available This study employs the regional Community Multiscale Air Quality (CMAQ model to examine seasonal and diurnal variations of boundary layer ozone (O₃ over East Asia. We evaluate the response of model simulations of boundary layer O₃ to the choice of chemical mechanisms, meteorological fields, boundary conditions, and model resolutions. Data obtained from surface stations, aircraft measurements, and satellites are used to advance understanding of O₃ chemistry and mechanisms over East Asia and evaluate how well the model represents the observed features. Satellite measurements and model simulations of summertime rainfall are used to assess the impact of the Asian monsoon on O₃ production. Our results suggest that summertime O₃ over Central Eastern China is highly sensitive to cloud cover and monsoonal rainfall over this region. Thus, accurate simulation of the East Asia summer monsoon is critical to model analysis of atmospheric chemistry over China. Examination of hourly summertime O₃ mixing ratios from sites in Japan confirms the important role of diurnal boundary layer fluctuations in controlling ground-level O₃. By comparing five different model configurations with observations at six sites, the specific mechanisms responsible for model behavior are identified and discussed. In particular, vertical mixing, urban chemistry, and dry deposition depending on boundary layer height strongly affect model ability to capture observed behavior. Central Eastern China appears to be the most sensitive region in our study to the choice of chemical mechanisms. Evaluation with TRACE-P aircraft measurements reveals that neither the CB4 nor the SAPRC99 mechanisms consistently capture observed behavior of key photochemical oxidants in springtime. However, our analysis finds that SAPRC99 performs somewhat better in simulating mixing ratios of H₂O₂ (hydrogen peroxide

To examine the complicity of British American Tobacco (BAT) in cigarette smuggling in Asia, and to assess the centrality of illicit trade to regional corporate strategy. Analysis of previously confidential documents from BAT's Guildford depository. An iterative strategy combined searches based on geography, organisational structure, and key personnel, while corporate euphemisms for contraband were identified by triangulation. BAT documents demonstrate the strategic importance of smuggling across global, regional, national, and local levels. Particularly important in Asia, contraband enabled access to closed markets, created pressure for market opening, and was highly profitable. Documents demonstrate BAT's detailed oversight of illicit trade, seeking to reconcile the conflicting demands of control and deniability. BAT documents demonstrate that smuggling has been driven by corporate objectives, indicate national measures by which the problem can be addressed, and highlight the importance of a coordinated global response via WHO's Framework Convention on Tobacco Control.

Privatizing Southeast Asia's electric power industries: phases, challenges, difficulties

Van Dang, G.

1995-01-01

The privatization of the power sector in South East Asia is part of a complex strategy, aimed a creating an efficient power production space, consisting of both national and international producers, although the latter will have to be selected according to their ability to ensure the most efficient service while implementing new technology. There is no single privatization model in S.E. Asia, but a wide variety of approaches, ranging from the most daring (e.g. Malaysia) to the most cautious (e.g. Thailand). For centrally planned economies (such as Vietnam and Laos), the approach will still be dictated by strategic demands to the detriment of the obvious financial advantages of total privatization of the power sector. Nevertheless, in most S.E. Asian countries, the process seems to be inexorably heading towards a situation where the political authorities will induce competition between the different groups of operators on the power production market. The basic challenge to governments of the region is to ensure the coexistence and smooth operation of the new public private relations within the power sector. (author). 19 refs

Central Asia is culturally and demographically diverse, both between and within its respective countries. That diversity is represented in the range of individual, network, community, and structural risks for female sex workers (FSWs) regionally. FSWs have several risk factors for HIV acquisition and transmission including behavioral, biological, and structural risk factors. Across Central Asia, sexual risks have become conflated with risks associated with injection and non-injection illicit drug use. Peer-reviewed literature databases and gray literature were searched for articles on sex work in Central Asia. The medial subject heading (MeSH) of "sex work" was cross-referenced with terms associated with Uzbekistan, Tajikistan, Turkmenistan, Kazakhstan, Kyrgyzstan, Mongolia, and Afghanistan. HIV prevalence data for FSWs suggest sustained or increasing prevalence in the region. There are increasing data directly linking HIV among FSWs to injection drug use; odds of HIV are up to 20 times higher among FSWs reporting injecting drug use. Though injecting drug use among FSWs is rare in some settings, recreational drugs and alcohol use limits other risk reduction behaviors, such as condom use. The Central Asian HIV epidemic has traditionally been assumed to be driven nearly exclusively by drug use, resulting in surveillance systems focused on parenteral transmission. The reviewed data highlight limited attention to characterizing the burden of HIV and risk factors for HIV acquisition and transmission among FSWs who use drugs. Moving forward will require enhanced HIV surveillance and research to inform HIV prevention approaches to address all levels of HIV risks affecting FSWs in Central Asia. Copyright © 2013.

Chronic hepatitis C (CHC) infection poses a global healthcare burden, being associated with serious complications if untreated. The prevalence of hepatitis C virus (HCV) infection is highest in areas of Central, South, and East Asia; over 50% of HCV patients worldwide live in the region, where HCV genotypes 1b, 2, 3, and 6 are the most prevalent. Treatment outcomes for chronic hepatitis C vary by ethnicity, and Asian patients achieve higher sustained virologic response rates following interferon (IFN)-based therapy than non-Asians. However, low efficacy, poor safety profile, and subcutaneous administration limit the use of IFN-based therapies. Superior virologic outcomes have been observed with different classes of direct-acting antivirals (DAAs) alone or in combination, and several all-oral DAA regimens are available in Asia. These regimens have shown excellent efficacy and favorable tolerability in clinical trials, yet there is a need for further studies of DAAs in a real world context, particularly in Asia. Furthermore, IFN-free treatment may not be accessible for many patients in the region, and IFN-based regimens remain an option in some countries. There is a need to improve current clinical practices for HCV management in Asia, including effective screening, disease awareness, and prevention programs, and to further understand the cost-effectiveness of IFN-free regimens. The evolution of potent treatments makes HCV eradication a possibility that should be available to all patients. However, access to these therapies in Asian countries has been slow, primarily because of economic barriers that continue to present a hurdle to optimal treatment. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

[Ethnic conflicts and environmental degradation in Central Asia. The Ferghana valley and northern Kazakhstan].

Science.gov (United States)

De Cordier, B

1996-01-01

This work seeks to demonstrate that the combination of ecological degradation, demographic pressure, and ethnic heterogeneity in Central Asia constitute a serious threat to the future stability of the region. The predominantly rural Ferghana Valley and Northern Kazakhstan suffer from shortages of water and land and from unemployment that leads to extensive out-migration to cities suffering from decline in their Soviet-era industries. The problem in the Ferghana Valley began with Tsarist conquest of the valley in 1876 and the subsequent imposition of cotton cultivation, which was greatly expanded by the Soviet Union. The Ferghana Valley, despite being a natural unit, was divided between Uzbekistan, Tajikistan, and Kyrgyzstan in the 1920s and 1930s, and remains divided between the independent states. The current population of 11 million is ethnically diverse, with Uzbeks in the majority and increasing most rapidly. Immigration from the Caucasus since 1950 added to the tension. Future peace will depend on such factors as whether the neo-Communist political regime chooses to incite ethnic hostilities, the manner in which land is redistributed, and the outcome of struggles for control of the flourishing narcotics trade. The northern Kazakhstan region was designated a pioneer wheat-growing region by Soviet planners in 1954. Russian and Ukrainian migrants established between 1954 and 1956 are today the predominant population sector, but feel their privileged position threatened by nationalist policies making Kazakh the official language and giving preference in employment to Kazakhs. Resettlement of Kazakhs from Mongolia, China, and Afghanistan in the region and the high Kazakh birth rate increase tensions. Grain production initially grew rapidly, but the mediocre soil and erosion-inducing constant dry winds have caused production to stagnate or decline. Regional disputes within Kazakhstan complicate the situation. Northern Kazakhstan, with its industrial development, is

The traditional consumption of edible insects is common in one third of the world's population, mostly in Latin America, Africa and Asia. There are over one thousand identified species of insects eaten in some stage of their life cycle; and they play important roles in ensuring food security. The most common way to collect insects are from the wild, which is seasonal with limited availability and has an increasing demand resulting in a disruption to the ecosystem. There is a growing interest shown in rearing insects for commercial purposes, and an industrial scale production will be required to ensure steady supplies. Industrial production will need to take into account the living environment of insects, the nutritional composition of their feed and the overall efficiency of the production system. We provide a short overview on the consumption of and rearing insects in Africa, Asia and Europe. For Africa, a snapshot is given for Nigeria, Ghana, Central African Republic, Kenya and Uganda, while the following countries are reported for Asia: China, Japan, Lao People's Democratic Republic, Thailand and Vietnam. In addition, a list of insect species with the highest potential for food and feed in the European Union is provided with some reference to The Netherlands and Finland. The review concludes that there is need to better understand the rearing and farming procedures that will yield high quality edible insects in Africa, Asia and Europe.

Molecular anthropological studies of the populations in and around East Asia have resulted in the discovery that most of the Y-chromosome lineages of East Asians came from Southeast Asia. However, very few Southeast Asian populations had been investigated, and therefore, little was known about the purported migrations from Southeast Asia into East Asia and their roles in shaping the genetic structure of East Asian populations. Here, we present the Y-chromosome data from 1,652 individuals belonging to 47 Mon-Khmer (MK) and Hmong-Mien (HM) speaking populations that are distributed primarily across Southeast Asia and extend into East Asia. Haplogroup O3a3b-M7, which appears mainly in MK and HM, indicates a strong tie between the two groups. The short tandem repeat network of O3a3b-M7 displayed a hierarchical expansion structure (annual ring shape), with MK haplotypes being located at the original point, and the HM and the Tibeto-Burman haplotypes distributed further away from core of the network. Moreover, the East Asian dominant haplogroup O3a3c1-M117 shows a network structure similar to that of O3a3b-M7. These patterns indicate an early unidirectional diffusion from Southeast Asia into East Asia, which might have resulted from the genetic drift of East Asian ancestors carrying these two haplogroups through many small bottle-necks formed by the complicated landscape between Southeast Asia and East Asia. The ages of O3a3b-M7 and O3a3c1-M117 were estimated to be approximately 19 thousand years, followed by the emergence of the ancestors of HM lineages out of MK and the unidirectional northward migrations into East Asia.

Energy security, trans-national pipelines and China's role in Asia

Energy Technology Data Exchange (ETDEWEB)

Seaman, J.

2010-07-01

In recent decades, China's transformation from a regional energy supplier to one of the world's largest net energy importers, in particular with regards to oil and gas, has led to an increasing sense of energy insecurity in Chinese policy circles. Guaranteeing adequate supplies of energy to fuel economic growth is a central element in Beijing's efforts to maintain legitimacy in the face of economic reform and transformation. To combat energy insecurity a number of initiatives are being undertaken to diversify energy inputs, suppliers, and the means of their transport. Among these initiatives are a series of trans-national pipeline projects that will transport oil and gas from Eastern Siberia, Central Asia, and Southeast Asia, effectively reducing China's overall reliance on international sea lanes and maritime choke-points, in particular the Strait of Malacca. An analysis of these projects can shed light on how China's energy security policies are playing out on a regional level, how they are complicated and aided by various competing and converging interests of regional actors, and how they are re-shaping traditional regional dependencies. Indeed, more complex interdependencies among suppliers, consumers and transit states in continental Asia seem to be emerging as a consequence of China's growing role as an energy consumer. In the end, these pipelines help to diversify China's oil and gas suppliers and transport routes, easing its reliance on Middle Eastern oil and maritime transit, but they are by no means an alternative to the latter. China will continue to rely heavily on international oil markets and maritime shipping routes to deliver Middle Eastern oil. Suring up international markets and finding means to cooperate on international maritime security issues are thus and will remain in China's best interest. (author)

Between China and South Asia: A Middle Asian corridor of crop dispersal and agricultural innovation in the Bronze Age.

The period from the late third millennium BC to the start of the first millennium AD witnesses the first steps towards food globalization in which a significant number of important crops and animals, independently domesticated within China, India, Africa and West Asia, traversed Central Asia greatly increasing Eurasian agricultural diversity. This paper utilizes an archaeobotanical database (AsCAD), to explore evidence for these crop translocations along southern and northern routes of interaction between east and west. To begin, crop translocations from the Near East across India and Central Asia are examined for wheat ( Triticum aestivum ) and barley ( Hordeum vulgare ) from the eighth to the second millennia BC when they reach China. The case of pulses and flax ( Linum usitatissimum ) that only complete this journey in Han times (206 BC-AD 220), often never fully adopted, is also addressed. The discussion then turns to the Chinese millets, Panicum miliaceum and Setaria italica , peaches ( Amygdalus persica ) and apricots ( Armeniaca vulgaris ), tracing their movement from the fifth millennium to the second millennium BC when the Panicum miliaceum reaches Europe and Setaria italica Northern India, with peaches and apricots present in Kashmir and Swat. Finally, the translocation of japonica rice from China to India that gave rise to indica rice is considered, possibly dating to the second millennium BC. The routes these crops travelled include those to the north via the Inner Asia Mountain Corridor, across Middle Asia, where there is good evidence for wheat, barley and the Chinese millets. The case for japonica rice, apricots and peaches is less clear, and the northern route is contrasted with that through northeast India, Tibet and west China. Not all these journeys were synchronous, and this paper highlights the selective long-distance transport of crops as an alternative to demic-diffusion of farmers with a defined crop package.

Peritoneal Dialysis in Asia.

2015-12-01

There is a growing demand of dialysis in Asia for end-stage renal failure patients. Diabetes mellitus is the leading cause of end-stage renal failure in many countries in Asia. The growth of peritoneal dialysis (PD) in Asia is significant and seeing a good trend. With the enhanced practices of PD, the quality of care in PD in Asia is also improved. Overall, PD and hemodialysis (HD) are comparable in clinical outcome. There is a global trend in the reduction of peritonitis rates and Asian countries also witness such improvement. The socio-economic benefits of PD for end-stage renal failure patients in both urban and rural areas in the developed and developing regions of Asia are an important consideration. This can help to reduce the financial burden of renal failure in addressing the growing demand of patients on dialysis. Initiatives should be considered to further drive down the cost of PD in Asia. Growing demand for dialysis by an increasing number of end-stage renal failure patients requires the use of a cost-effective quality dialysis modality. PD is found to be comparable to HD in outcome and quality. In most countries in Asia, PD should be more cost-effective than HD. A 'PD-first' or a 'PD as first considered therapy' policy can be an overall strategy in many countries in Asia in managing renal failure patients, taking the examples of Hong Kong and Thailand. (1) PD is cheaper than HD and provides a better quality of life worldwide, but its prevalence is significantly lower than that of HD in all countries, with the exception of Hong Kong. Allowing reimbursement of PD but not HD has permitted to increase the use of PD over HD in many Asian countries like Hong Kong, Vietnam, Taiwan, Thailand, as well as in New Zealand and Australia over the last years. In the Western world, however, HD is still promoted, and the proportion of patients treated with PD decreases. Japan remains an exception in Asia where PD penetration is very low.

Aerosol samples were collected during the scientific expedition to Mt. Bogda in July-August, 2009. The major inorganic ions (Na( + ), NH⁺₄, K( + ), Mg(2 + ), Ca(2 + ), Cl( - ), SO²⁻₄, and NO⁻₃) of the aerosols were determined by ion chromatography. SO²⁻₄, NO⁻₃, and Ca(2 + ) were the dominate ions, with the mean concentrations of 0.86, 0.56, and 0.28 μg m⁻³, respectively. These mean ion concentrations were generally comparable with the background conditions in remote site of Xinjiang, while much lower than those in Ürümqi. Morphology and elemental compositions of 1,500 particles were determined by field emission scanning electron microscopy equipped with an energy dispersive X-ray spectrometer. Based on the morphology and elemental compositions, particles were classed into four major groups: soot (15.1%), fly ash (4.7%), mineral particles (78.9%), and little other matters (0.8% Fe-rich particles and 0.5% unrecognized particles). Presence of soot and fly ash particles indicated the influence of anthropogenic pollutions, while abundance mineral particles suggested that natural processes were the primary source of aerosols over this region, coinciding with the ionic analysis. Backward air mass trajectory analysis suggested that Ürümqi may contribute some anthropogenic pollution to this region, while the arid and semi-arid regions of Central Asia were the primary source.

Is epilepsy truly an "African ailment"? We aimed to determine this, since international health agencies often refer to epilepsy as an African disease and the scientific literature has spoken the same tone. Various published materials, mainly reports, articles, were used to gather Asian and African evidence on various aspects of epilepsy and many of its risk and associated factors. Our results suggest that in no way can epilepsy be considered as an African ailment and such characterization is most likely based on popular beliefs rather than scientific evidence. In comparison to Africa, Asia has a 5.0% greater burden from all diseases, and is 17.0% more affected from neuropsychiatric disorders (that include epilepsy). Given that more countries in Asia are transitioning, there may be large demographic and lifestyle changes in the near future. However these changes are nowhere close to those expected in Africa. Moreover, 23 million Asians have epilepsy in comparison to 3.3 million Africans and 1.2 million sub-Saharan Africans. In comparison to Africa, Asia has more untreated patients, 55.0% more additional epilepsy cases every year, because of its larger population, with greater treatment cost and possibly higher premature mortality. Of several associated factors discussed herein, many have more importance for Asia than Africa. The current state of epilepsy in Asia is far less than ideal and there is an urgent need to recognize and accept the importance of epilepsy in Asia. In no way can epilepsy be considered as an African ailment. This is most likely based on popular beliefs rather than scientific evidence.

New trends on obesity and NAFLD in Asia.

Science.gov (United States)

Fan, Jian-Gao; Kim, Seung-Up; Wong, Vincent Wai-Sun

2017-10-01

Traditionally, obesity and its related diseases have been considered a problem in Western countries. However, in the past two decades, urbanisation in many Asian countries has led to a sedentary lifestyle and overnutrition, setting the stage for the epidemic of obesity. This article reviews the epidemiological trend of obesity in Asia, with special emphasis on the emerging condition of non-alcoholic fatty liver disease (NAFLD). Currently, the population prevalence of NAFLD in Asia is around 25%, like many Western countries. While hepatocellular carcinoma and end-stage liver disease secondary to NAFLD remain uncommon, a rising trend has emerged. Around 8-19% of Asians with body mass indexes less than 25kg/m 2 are also found to have NAFLD, a condition often described as "lean" or "non-obese" NAFLD. Although this condition is generally less severe than that in more obese patients, steatohepatitis and fibrotic disease are well recognized. Central adiposity, insulin resistance and weight gain are major risk factors, and genetic predisposition, such as the PNPLA3 polymorphism appears to be more important in the development of NAFLD in the non-obese population. Lifestyle modification remains the cornerstone of management for obesity and NAFLD, but few patients can achieve adequate weight reduction and even fewer can maintain the weight in the long run. While pharmacological agents have entered phase III development for steatohepatitis, Asian patients are under-represented in most drug trials. Future studies should define the optimal management of obesity and NAFLD in Asia. Copyright © 2017 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

Uncertainty in biogenic isoprene emissions and its impacts on tropospheric chemistry in East Asia

Han, K.M.; Park, R.S.; Kim, H.K.; Woo, J.H.; Kim, J.; Song, C.H.

2013-01-01

In this study, the accuracy of biogenic isoprene emission fluxes over East Asia during two summer months (July and August) was examined by comparing two tropospheric HCHO columns (Ω HCHO ) obtained from the SCIAMACHY sensor and the Community Multi-scale Air Quality (CMAQ v4.7.1) model simulations, using three available biogenic isoprene emission inventories over East Asia: i) GEIA, ii) MEGAN and iii) MOHYCAN. From this comparative analysis, the tropospheric HCHO columns from the CMAQ model simulations, using the MEGAN and MOHYCAN emission inventories (Ω CMAQ, MEGAN and Ω CMAQ, MOHYCAN ), were found to agree well with the tropospheric HCHO columns from the SCIAMACHY observations (Ω SCIA ). Secondly, the propagation of such uncertainties in the biogenic isoprene emission fluxes to the levels of atmospheric oxidants (e.g., OH and HO 2 ) and other atmospheric gaseous/particulate species over East Asia during the two summer months was also investigated. As the biogenic isoprene emission fluxes decreased from the GEIA to the MEGAN emission inventories, the levels of OH radicals increased by factors of 1.39 and 1.75 over Central East China (CEC) and South China, respectively. Such increases in the OH radical mixing ratios subsequently influence the partitioning of HO y species. For example, the HO 2 /OH ratios from the CMAQ model simulations with GEIA isoprene emissions were 2.7 times larger than those from the CMAQ model simulations based on MEGAN isoprene emissions. The large HO 2 /OH ratios from the CMAQ model simulations with the GEIA biogenic emission were possibly due to the overestimation of GEIA biogenic isoprene emissions over East Asia. It was also shown that such large changes in HO x radicals created large differences on other tropospheric compounds (e.g., NO y chemistry) over East Asia during the summer months. - Highlights: • GEIA isoprene emissions were possibly overestimated over East Asia. • Using MEGAN or MOHYCAN emissions in CMAQ well captured

The USA and proliferation in Northeast Asia

International Nuclear Information System (INIS)

Weeks, S.B.

1995-01-01

United States policy on proliferation in Northeast Asia poses a test of balance between general US global non-proliferation goals and specific US regional security goals for Northeast Asia. US policy on proliferation in Northeast Asia further poses a test of priorities for US bilateral relations with the key Northeast Asian states, as non-proliferation and regional security goals must be weighed against other (e.g., economic, human rights) declared US policy goals. The result is a US policy equation for Northeast Asia proliferation that is considerably more complex in execution than might be expected from the simple statement of the US goal to avoid nuclear proliferation in Northeast Asia. The question of security assurances - both negative and positive - may be closely related to US policies to avoid proliferation in Northeast Asia

Full Text Available Southeast Asia countries were developing countries, with the rapid development for a better living condition leads to longer life expectancy, which increased total population. It may result in increased the demand of pharmaceutical in domestic use and or in hospital. Although most wastewater treatment plants (WWTPs met the local authority’s regulatory requirement, there are still many pharmaceutical compound incompletely removed and discharge to the water stream and enter the environment. Recently many studies and researches have published on the occurrence and source as well as the fate of pharmaceuticals all over the world including Asia. As part of Asia region, Southeast Asia countries (Malaysia, Philippines, Singapore, Thailand, Vietnam, Brunei, Cambodia, and Lao PDR seem has lack of research knowledge and information regarding this emerging pollutant issues compared to developed Asia country as China, Korea and Hong Kong. In this paper, it will review recent studies occurrences (surface and wastewater on most common pharmaceuticals with several recommendations to overcome and thus summarise the actual situation in Southeast Asia.

Woźniacka, Anna; Sysa-Jędrzejowska, Anna; Jurowski, Piotr; Jabłkowski, Maciej; Kot, Marek

2015-12-10

Behçet's disease (BD) is a multiorgan inflammatory disease of complex and not entirely elucidated etiology, which was originally diagnosed in patients with aphthous stomatitis, genital ulcerations and ocular manifestations. The entity is endemic in countries of Eastern and Central Asia, especially Turkey and Iran, but rarely seen in Central Europe. As there are no specific diagnostic laboratory tests or histopathologic findings which confirm the preliminary diagnosis, the final diagnosis should be based on clinical criteria. Frequently a definitive diagnosis is established within several years or months after the first manifestations appear. The increased number of cases, recently described worldwide also in the Polish population, indicates that the disease could spread out of endemic areas. The aim of this manuscript is to present the clinical picture, diagnosis criteria and therapeutic approaches of this "international disease" which currently is observed not only in emigrants from Asia but also in native Polish citizens.

Diabetic Retinopathy in the Asia-Pacific.

2018-01-01

Diabetic retinopathy (DR), the most common complication of diabetes mellitus, is the leading cause of new cases of blindness in middle-aged and elderly in the Asia-Pacific. It has been estimated that 51% of all those with blindness due to DR globally (n = 424,400) and 56% of those with visual impairment due to DR (2.1 million) come from the Asia-Pacific. Prevalence of DR among those with diabetes ranged from 10% in India to 43% in Indonesia within the Asia-Pacific. Awareness of DR among persons with diabetes ranged from 28% to 84%. Most common modifiable risk factors for DR in the Asia-Pacific were hyperglycemia, blood pressure, dyslipidemia, and obesity. Implementation of systematic screening programs for DR and advancement in telemedicine screening methods have increased patient coverage and cost-effectiveness, though there are still numerous factors impeding screening uptake in the low-middle income regions of the Asia-Pacific. Management and treatment of DR in the Asia-Pacific is mainly limited to traditional laser retinopexy, but it is suboptimal despite new clinical approaches such as use of intravitreal anti.vascular endothelial growth factor and steroids due to limited resources. Further research and data are required to structure a more cost-effective public healthcare program and more awareness-building initiatives to increase the effectiveness of DR screening programs.

Nuclear nonproliferation strategy in Asia

International Nuclear Information System (INIS)

Jenkins, F.W.

1989-07-01

The most immediate danger of a further spread of nuclear weapons in Asia is in South Asia, where both India and Pakistan have developed the means of producing nuclear explosive materials. In East Asia, North Korea appears to be in the early stages of a weapon-related nuclear program, and before the end of the century South Korea or Taiwan could revive their past efforts to move closer to a nuclear weapons capability. Over the longer run, Japan could conceivably decide to abandon its present strong opposition to the acquisition of nuclear Weapons. At present, the United States has largely separate approaches to the nuclear weapon proliferation problems in South Asia and in East Asia. This paper argues that these separate approaches should be strengthened and integrated into a broader regional nonproliferation strategy. This regional strategy would have three major strands: inducing India and Pakistan to agree not to produce nuclear weapons or test nuclear explosive devices for a specific period; bolstering the existing nonproliferation regime, principally by maintaining nonproliferation incentives and involving China more in the nonproliferation regime; and encouraging regional cooperation in peaceful uses of nuclear energy

Comparison of different wind data interpolation methods for a region with complex terrain in Central Asia

Reinhardt, Katja; Samimi, Cyrus

2018-01-01

While climatological data of high spatial resolution are largely available in most developed countries, the network of climatological stations in many other regions of the world still constitutes large gaps. Especially for those regions, interpolation methods are important tools to fill these gaps and to improve the data base indispensible for climatological research. Over the last years, new hybrid methods of machine learning and geostatistics have been developed which provide innovative prospects in spatial predictive modelling. This study will focus on evaluating the performance of 12 different interpolation methods for the wind components \\overrightarrow{u} and \\overrightarrow{v} in a mountainous region of Central Asia. Thereby, a special focus will be on applying new hybrid methods on spatial interpolation of wind data. This study is the first evaluating and comparing the performance of several of these hybrid methods. The overall aim of this study is to determine whether an optimal interpolation method exists, which can equally be applied for all pressure levels, or whether different interpolation methods have to be used for the different pressure levels. Deterministic (inverse distance weighting) and geostatistical interpolation methods (ordinary kriging) were explored, which take into account only the initial values of \\overrightarrow{u} and \\overrightarrow{v} . In addition, more complex methods (generalized additive model, support vector machine and neural networks as single methods and as hybrid methods as well as regression-kriging) that consider additional variables were applied. The analysis of the error indices revealed that regression-kriging provided the most accurate interpolation results for both wind components and all pressure heights. At 200 and 500 hPa, regression-kriging is followed by the different kinds of neural networks and support vector machines and for 850 hPa it is followed by the different types of support vector machine and

CORRUPTION AND FOREIGN DIRECT INVESTMENT IN EAST ASIA AND SOUTH ASIA: AN ECONOMETRIC STUDY

Directory of Open Access Journals (Sweden)

Rahim M. Quazi

2014-04-01

Full Text Available Many recent FDI studies have focused on the effects of corruption on FDI inflows. Theoretically, corruption can act as either a grabbing hand by raising uncertainty and transaction costs, which should impede FDI, or a helping hand by “greasing” the wheels of commerce in the presence of weak regulatory framework, which should facilitate FDI. This study analyzes the impact of corruption on FDI inflows in East Asia and South Asia – two regions that have recently received huge FDI inflows. Using GLS methodology with 1995-2011 panel data, this study finds that the impact of corruption on FDI is significantly negative and robust, which validates the “grabbing hand” hypothesis. It is also found that, even after accounting for the economic fundamentals, East Asia seems to enjoy a locational advantage in attracting FDI vis-à-vis South Asia. These results further our knowledge of the FDI dynamics, which policymakers should find helpful in devising pro-FDI strategies.

The expansion of rubber (Hevea brasiliensis) cultivation to higher latitudes and higher elevations in southeast Asia is part of a dramatic shift in the direction of rural land cover change in the region toward more tree covered landscapes. To investigate the possible effects of increasing rubber cultivation in the region on ecosystem services including water cycling, eddy covariance towers were established to measure ecosystem fluxes within two rubber plantations, one each in Bueng Kan, northeastern Thailand, and Kampong Cham, central Cambodia. The results show that evapotranspiration (ET) at both sites is strongly related to variations in available energy and leaf area, and moderately controlled by soil moisture. Measured mean annual ET was 1128 and 1272 mm for the Thailand and Cambodia sites, respectively. After adjustment for energy closure, mean annual was estimated to be 1211 and 1459 mm yr at the Thailand and Cambodia sites, respectively. Based on these estimates and that of another site in Xishuangbanna, southwestern China, it appears that of rubber is higher than that of other tree dominated land covers in the region, including forest. While measurements by others in non rubber tropical ecosystems indicate that at high net radiation sites is at most only slightly higher than for sites with lower net radiation, mean annual rubber increases strongl with increasing net radiation across the three available rubber plantation observation sites. With the continued expansion of tree dominated land covers, including rubber cultivation, in southeast Asia, the possible association between commercially viable, fast growing tree crop species Giambelluca et al. Evapotranspiration of rubber (Havea brasiliensis) cultivated at two sites in southeast Asia and their relatively high water use raises concerns about potential effects on water and food security.

The Iranian connection: the geo-economics of exporting Central Asian energy via Iran

International Nuclear Information System (INIS)

Stauffer, T.R.

1997-01-01

The prospect of exporting Caspian Sea crude oil production via a transit route through Iran is discussed. There are many political and economic barriers that are preventing the establishment of a transit route to bring the landlocked hydrocarbon resources of Azerbaijan and Central Asia to world oil markets. A route via Iran is most appealing because of the existing system of pipelines and export facilities already in place there, plus its close geographic location to Central Asia. Close to 2 MMb/d of production from the Caspian region could be accommodated at under $1.50/barrel transit costs. However, the opposition from the United States and Israel to any Iranian connection for the Caspian Sea production is well documented. The Russians, too, are opposed to any export option for Caucasian or Central Asian crude production that would bypass Russia because it would reduce its economic leverage over the new republics. It is widely believed that export through Iran would be more beneficial to the individual state governments by providing them with greater net well head revenues, as well as in reinforcing their independence at the expense of the central government in Moscow

Geology and undiscovered resource assessment of the potash-bearing Central Asia Salt Basin, Turkmenistan, Uzbekistan, Tajikistan, and Afghanistan: Chapter AA in Global mineral resource assessment

2016-03-23

Undiscovered potash resources in the Central Asia Salt Basin (CASB) of Turkmenistan, Uzbekistan, Tajikistan, and Afghanistan were assessed as part of a global mineral resource assessment led by the U.S. Geological Survey. The term “potash” refers to potassium-bearing, water-soluble salts derived from evaporite basins, where seawater dried up and precipitated various salt compounds; the word for the element “potassium” is derived from potash. Potash is produced worldwide at amounts exceeding 30 million metric tons per year, mostly for use in fertilizers. The term “potash” is used by industry to refer to potassium chloride, as well as potassium in sulfate, nitrate, and oxide forms. For the purposes of this assessment, the term “potash” refers to potassium ores and minerals and potash ore grades. Resource and production values are usually expressed by industry in terms of K2O (potassium oxide) or muriate of potash (KCl, potassium chloride).

U.S. coal outlook in Asia

International Nuclear Information System (INIS)

Johnson, C.J.

1997-02-01

Coal exports from the US to Asia are declining over time as a result of (1) increased competition from coal suppliers within the Asia-Pacific region, (2) changing steel making technologies, (3) decreased emphasis on security of coal supplies, and (4) deregulation of the energy industry--particularly electric utilities. There are no major changes on the horizon that are likely to alter the role of the US as a modest coal supplier to the Asia-Pacific region. The downward trend in US coal exports to Asia is expected to continue over the 1997--2010 period. But economic and policy changes underway in Asia are likely to result in periodic coal shortages, lasting a few months to a year, and short term increased export opportunities for US coal. US coal exports to Asia are projected to fluctuate within the following ranges over the 2000--2010 period: 10--17 million tons in total exports, 6--12 million tons in thermal coal exports, and 4--9 million tons in coking coal exports. The most important role for US coal, from the perspective of Asian coal importing countries, is to ensure a major alternative source of coal supplies that can be turned to in the event of unforeseen disruptions in coal supplies from the Asia-Pacific region or South Africa. However, the willingness of consumers to pay a premium to ensure US export capacity is declining, with increased emphasis on obtaining the lowest cost coal supplies

RECENT GEODYNAMICS OF INTRACONTINENTAL AREAS: INSTRUMENTAL AND GEOMORPHOLOGICAL ASSESSMENT OF CRUSTAL MOVEMENTS AND DEFORMATION IN CENTRAL ASIA

2014-01-01

Full Text Available Studies of recent geodynamics have been conducted by the Institute of the Earth’s Crust, SB RAS since 1998. Present-day crustal deformations are monitored at the geodynamic GPS polygon established by the Laboratory of Recent Geodynamics in the Mongol-Baikal region. Original methods and techniques using specialized equipment are applied to research intra-continental tectonic deformation and have already provided original scientific results. Independent data are received concerning the onset and character of processes of neotectonic activation and the state of stresses and deformation of the crust in the southern part of Siberia and in Mongolia. A model of the Late Cenozoic and contemporary geodynamics of the Mongol-Siberian mobile area is proposed. With application of GPS geodesy methods, quantitative parameters of present-day horizontal movements and deformations are determined for Central Asia and a part of the Far East at different scale levels. Present-day velocities of extension of the Baikal rift are estimated, and parameters of rotation of the Amur plate relative to Eurasia are calculated. Data on long-term and contemporary deformation are subject to comparative analyses. The Laboratory develops studies of present-day and historical seismicity in relation to processes of contemporary faulting in active tectonic zones of inter-plate boundaries and diffusive activation of subactive intraplate territories. The first results are obtained in studies of local crustal deformation by methods of satellite radar interferometry and ground polygonometry. Jointly with other institutes of SB RAS, the Laboratory conducts instrumental studies of interaction between the lithosphere and the ionosphere. Looking further ahead, the main scientific fields and prospects of the Laboratory are highlighted.  

Malaria successes and challenges in Asia.

Bhatia, Rajesh; Rastogi, Rakesh Mani; Ortega, Leonard

2013-12-01

Asia ranks second to Africa in terms of malaria burden. In 19 countries of Asia, malaria is endemic and 2.31 billion people or 62% of the total population in these countries are at risk of malaria. In 2010, WHO estimated around 34.8 million cases and 45,600 deaths due to malaria in Asia. In 2011, 2.7 million cases and > 2000 deaths were reported. India, Indonesia, Myanmar and Pakistan are responsible for >85% of the reported cases (confirmed) and deaths in Asia. In last 10 yr, due to availability of donor's fund specially from Global fund, significant progress has been made by the countries in Asia in scaling-up malaria control interventions which were instrumental in reducing malaria morbidity and mortality significantly. There is a large heterogeneity in malaria epidemiology in Asia. As a result, the success in malaria control/elimination is also diverse. As compared to the data of the year 2000, out of 19 malaria endemic countries, 12 countries were able to reduce malaria incidence (microscopically confirmed cases only) by 75%. Two countries, namely Bangladesh and Malaysia are projected to reach 75% reduction by 2015 while India is projected to reach 50-75% only by 2015. The trend could not be assessed in four countries, namely Indonesia, Myanmar, Pakistan and Timor-Leste due to insufficient consistent data. Numerous key challenges need to be addressed to sustain the gains and eliminate malaria in most parts of Asia. Some of these are to control the spread of resistance in Plasmodium falciparum to artemisinin, control of outdoor transmission, control of vivax malaria and ensuring universal coverage of key interventions. Asia has the potential to influence the malaria epidemiology all over the world as well as to support the global efforts in controlling and eliminating malaria through production of quality-assured ACTs, RDTs and long-lasting insecticidal nets.

Full Text Available Southeast Asia has historically been a meeting point between East Asia and South Asia before Western colonialism opened the region to the West and to the winds of global modernization. Since Japan’s coercive decolonization during the Second World War, the dominant outside influences have come from the United States and from the People’s Republic of China. The post-Cold War era began with a withdrawal of both China’s and US power projection from Southeast Asia, facilitating the configuration of a triangular ménage à trios, with ASEAN expanding to include all of Southeast Asia and introducing a number of extended forums intended to socialize the rest of East Asia into the ASEAN way. The “rise of China” occurred within this friendly context, though beginning around 2010 its strategic implications began to appear more problematic with the mounting dispute over the issue of the South China Sea.

Ancient farmers experienced climate change at the local level: through variations in the yields of their staple crops. However, archaeologists have had difficulty in determining where, when and how changes in climate impacted ancient farmers. We model how several key transitions in climate impacted the productivity of five rain-fed crops across Eurasia. Cooling events between 3750 and 3000 cal. BP lead humans in parts of the Tibetan Plateau and in Central Asia to diversify their crops. A second event at 2000 cal. BP lead farmers in Central China to also diversify their cropping systems and to develop man-made systems that allowed transport of grains from Southern to Northern China. In other areas where crop returns fared even worse, humans reduced their risk by increasing investment in nomadic pastoralism and developing long distance networks of trade that coalesced into the Silk Road. By translating changes in climatic variables into factors that mattered to ancient farmers, we situate the adaptive strategies they developed to deal with variance in crop returns in the context of environmental and climatic changes.

Historiography on Japan’s place within the world of maritime Asia has undergone dramatic reinterpretation in recent decades. Scholars of the early modern era have thoroughly demolished the shibboleth of sakoku (“closed country”, the supposed isolation of Tokugawa Japan before the sudden arrival of Western gunboats in the 1850s. The active pursuit of diplomatic and commercial ties by shogun and daimyo alike embedded Japan firmly within global circuits of exchange (e.g., Hellyer 2010; Toby 1984. Scholars of the modern era, for their part, have been inspired by the “imperial turn” to put overseas empires at the heart of national narratives. Bookending the Tokugawa and Meiji periods, the two studies under review here push the frontiers of this research agenda further. Noell Wilson’s political history focuses on the buildup of domainal defense on the coast and the devolution of shogunal monopoly on violence. At the heart of this dialectical relationship was the “Nagasaki system”—the security arrangements that originated in the eponymous port and were eventually implemented throughout Japan. Catherine Phipps’s economic history examines the commercial expansion of Meiji Japan by tracing maritime networks of exchange, transportation, and information at multiple spatial scales. Forged in the crucible of Western imperialism, such ties simultaneously compromised the sovereignty of the nation while laying the foundations for empire. Both works offer compelling cases for the centrality of maritime relations in understanding core issues in Japanese history...

We analyzed the source–receptor relationships for particulate polycyclic aromatic hydrocarbon (PAH) concentrations in northeastern Asia using an aerosol chemical transport model. The model successfully simulated the observed concentrations. In Beijing (China) benzo[a]pyren (BaP) concentrations are due to emissions from its own domain. In Noto, Oki and Tsushima (Japan), transboundary transport from northern China (>40°N, 40–60%) and central China (30–40°N, 10–40%) largely influences BaP concentrations from winter to spring, whereas the relative contribution from central China is dominant (90%) in Hedo. In the summer, the contribution from Japanese domestic sources increases (40–80%) at the 4 sites. Contributions from Japan and Russia are additional source of BaP over the northwestern Pacific Ocean in summer. The contribution rates for the concentrations from each domain are different among PAH species depending on their particulate phase oxidation rates. Reaction with O 3 on particulate surfaces may be an important component of the PAH oxidation processes. -- Highlights: •Source–receptor analysis was conducted for investigating PAHs in northeast Asia. •In winter, transboundary transport from China is large contribution in leeward. •Relative contribution from Korea, Japan, and eastern Russia is increased in summer. •This seasonal variation is strongly controlled by the meteorological conditions. •The transport distance is different among PAH species. -- Transboundary transport of PAHs in northeast Asia was investigated by source–receptor analysis

Systematic review, ambispective analysis of observational data. To make recommendations as to whether or not urgent surgical decompression is ever indicated as the optimal treatment for enhancing neurologic recovery in a patient with acute central cord injury without fracture or instability. There are currently no standards regarding the role and timing of decompression in acute traumatic central cord syndrome. In the setting of TCCS without spinal column instability, much controversy exists. We have performed a thorough literature search based on the following question: "Is there a role for urgent (within 24 hours from injury to surgery) surgical decompression in acute central cord syndrome without fracture or instability specifically to enhance neurologic recovery?" Data including patient demographics, mechanism of injury, comorbidities, neurologic status, and surgical treatment was analyzed from a multicenter STSG observational database. Outcome measured included ASIA Motor Score, ASIA Grade, Functional Independence Measure (FIM) Score, SF-36, Sphincter Disturbance, and Ambulatory status. Measures were recorded on admission, discharge, 6 months and 1 year. At 12-month follow-up, early surgery resulted in a 6.31 point greater improvement in total motor score than did the late surgery group, with a P = 0.0358. At 6-month follow-up, early surgery result in higher chance of improvement in ASIA Grade than late surgery, with an odds ratio = 3.39, while at 12-month follow-up early surgery resulted in a higher chance of improvement in ASIA Grade, with an odds ratio of 2.81. Patients who were operated on within 24 hours had 7.79 U more improvement in FIM Total Score than late surgery at 6 month follow-up, with P = 0.0474. The consensus of experts following review of relevant and examination of observational dataset concluded that it is reasonable and safe to consider early surgical decompression in patients with profound neurologic deficit (ASIA = C) and persistent

2012-10-01

Full Text Available Atmospheric concentrations of reactive nitrogen (N_r species from 2009 to 2011 are reported for ten sites in Xinjiang, China, an arid region of central Asia. Concentrations of NH₃, NO₂, particulate ammonium and nitrate (pNH₄⁺ and pNO₃⁻ showed large spatial and seasonal variation and averaged 7.71, 9.68, 1.81 and 1.13 μg N m⁻³, and PM₁₀ concentrations averaged 249.2 μg m⁻³ across all sites. Lower NH₃ concentrations and higher NO₂, pNH₄⁺ and pNO₃⁻ concentrations were found in winter, reflecting serious air pollution due to domestic heating in winter and other anthropogenic sources such as increased emissions from motor traffic and industry. The increasing order of total concentrations of N_r species was alpine grassland; desert, desert-oasis ecotone; desert in an oasis; farmland; suburban and urban ecosystems. Lower ratios of secondary particles (NH₄⁺ and NO₃⁻ were found in the desert and desert-oasis ecotone, while urban and suburban areas had higher ratios, which implied that anthropogenic activities have greatly influenced local air quality and must be controlled.

Future Heat Waves In Asia

2017-12-01

I will review recent work from my group on the impact of climate change on the intensity and frequency of heat waves in Asia. Our studies covered Southwest Asia, South Asia, East China, and the Maritime continent. In any of these regions, the risk associated with climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that the wet-bulb temperature is a useful variable to consider in describing the natural hazard from heat waves since it can be easily compared to the natural threshold that defines the upper limit on human survivability. Based on an ensemble of high resolution climate change simulations, we project extremes of wet-bulb temperature conditions in each of these four regions of Asia. We consider the business-as-usual scenario of future greenhouse gas emissions, as well as a moderate mitigation scenario. The results from these regions will be compared and lessons learned summarized.

Airborne dust from northern China influences air quality and regional climate in Asia during springtime. However, with the economic growth in China, increased emission of particulate air pollutants from industrial and vehicular sources will not only impact the earth's radiation balance, but also adversely affect human health year round. In addition, both of dust and aerosol pollutants can be transported swiftly across the Pacific affecting North America within a few days. Asian dust and pollutant aerosols can be detected by their colored appearance using current Earth observing satellites (e.g., MODIS, SeaWiFS, TOMS, etc.) and by sunphotometers deployed on the surface of the earth. Biomass burning has been a regular practice for land clearing and conversion in many countries, especially those in Africa, South America, and Southeast Asia. However, the climatology of Southeast Asia is very different than that of Africa and South America, such that large-scale biomass burning causes smoke to interact extensively with clouds during the peak-burning season of March to April. Globally significant sources of greenhouse gases (eg., CO2, CH4), chemically active gases (e.g., NO, CO, HC, CH3Br), and atmospheric aerosols are produced by biomass burning. These gases influence the Earth-atmosphere system, impacting both global climate and tropospheric chemistry. Some aerosols can serve as cloud condensation nuclei, which play a role in determining cloud lifetime and precipitation, altering the earth's radiation and water budgets. Biomass burning also affects the biogeochemical cycling of nitrogen and carbon compounds; the hydrological cycle; land surface reflectivity and emissivity; and ecosystem biodiversity and stability. Two NASA initiatives, EAST-AIRE (East Asian Study of Tropospheric Aerosols: an International Regional Experiment) and BASE-ASIA (Biomass-burning Aerosols in South East-Asia: Smoke Impact Assessment) will be presented.

Postoperative central nervous system infections (PCNSIs) are serious complications following neurosurgical intervention. We previously investigated the incidence and causative pathogens of PCNSIs at a resource-limited, neurosurgical center in south Asia. This follow-up study was conducted to analyze differences in PCNSIs at the same institution following only one apparent change: the operating room air filtration system. This was a retrospective study of all neurosurgical cases performed between December 1, 2013, and March 31, 2016 at our center. Providers, patient demographic data, case types, perioperative care, rate of PCNSI, and rates of other complications were reviewed. These results were then compared with the findings of our previous study of neurosurgical cases between June 1, 2012, and June 30, 2013. All 623 neurosurgical operative cases over the study period were reviewed. Four patients (0.6%) had a PCNSI, and no patients had a positive cerebrospinal fluid (CSF) culture. In the previous study, among 363 cases, 71 patients (19.6%) had a PCNSI and 7 (1.9%) had a positive CSF culture (all Gram-negative organisms). The differences in both parameters are statistically significant (P system inside the neurosurgical operating rooms; this environmental change occurred during the 5 months between the 2 studies. This study demonstrates the impact of environmental factors in reducing infections. Copyright © 2017 Elsevier Inc. All rights reserved.

“My Silk Road to You”: Re-imagining routes, roads, and geography in contemporary art of “Central Asia”

Directory of Open Access Journals (Sweden)

Diana T. Kudaibergenova

2017-01-01

Full Text Available This paper re-focuses the Silk Road discussions from the position of contemporary art in Central Asian region. Since the late 1980s contemporary art in Central Asia boomed and it eventually became an alternative public space for the discussion of cultural transformations, social and global processes and problems that local societies faced. Initially the questions raised by many artists concerned issues of lost identity and lost heritage during the period of Soviet domination in the region. Different artists started re-imagining the concept of the Self in their works and criticising the old rigid approaches to geography, history and mobility. Nomadic heritage became one of the central themes in contemporary art of Central Asia in the 1990s. Artists started experimenting with symbols of mobility, fluid borders and imagined geography of the “magic steppe” (see Kudaibergenova 2017, “Punk Shamanism”. Contemporary art in Central Asia continues to serve as a space for social critique and a space for search and re-conceptualisation of new fluid identities, geographies and region's place on the world map. In this paper I critically evaluate three themes connected to the symbolism of Silk Road heritage that many artists engage with – imagined geography, routes, roads and mobility. All three themes are present in the selected case studies of Gulnara Kasmalieva's and Muratbek Djumaliev's TransSiberian Amazons (2005 and A New Silk Road: Algorithm of Survival and Hope (2007 multi-channel video art, Victor and Elena Vorobievs' (NonSilk Road (2006 performance and photography, Almagul Menlibayeva's My Silk Road to You video-art and photography (2010–2011, Yerbossyn Meldibekov's series on imagining Central Asia and the Mountains of Revolution (2012–2015, and Syrlybek Bekbotaev's Kyrgyz Pass installation (2014–2015 as well as Defenders of Issyk Kul (2014.

Watcharapong Piyaphanee

Full Text Available BACKGROUND: Each year millions of travelers visit Southeast Asia where rabies is still prevalent. This study aimed to assess the risk of rabies exposure, i.e., by being bitten or licked by an animal, among travelers in Southeast Asia. The secondary objective was to assess their attitudes and practices related to rabies. METHODOLOGY/PRINCIPAL FINDINGS: Foreign travelers departing to the destination outside Southeast Asia were invited to fill out the study questionnaire in the departure hall of Bangkok International Airport. They were asked about their demographic profile, travel characteristics, pre-travel health preparations, their possible exposure and their practices related to rabies during this trip. From June 2010 to February 2011, 7,681 completed questionnaires were collected. Sixty-two percent of the travelers were male, and the median age was 32 years. 34.0% of the participants were from Western/Central Europe, while 32.1% were from East Asia. Up to 59.3% had sought health information before this trip. Travel clinics were the source of information for 23.6% of travelers. Overall, only 11.6% of the participants had completed their rabies pre-exposure prophylaxis, and 15.3% had received only 1-2 shots, while 73.1% had not been vaccinated at all. In this study, the risk of being bitten was 1.11 per 100 travelers per month and the risk of being licked was 3.12 per 100 travelers per month. Among those who were bitten, only 37.1% went to the hospital to get post exposure treatment. Travelers with East Asian nationalities and longer duration of stay were significantly related to higher risk of animal exposure. Reason for travel was not related to the risk of animal exposure. CONCLUSIONS: Travelers were at risk of being exposed to potentially rabid animals while traveling in Southeast Asia. Many were inadequately informed and unprepared for this life-threatening risk. Rabies prevention advice should be included in every pre-travel visit.

In this study, the accuracy of biogenic isoprene emission fluxes over East Asia during two summer months (July and August) was examined by comparing two tropospheric HCHO columns (Ω{sub HCHO}) obtained from the SCIAMACHY sensor and the Community Multi-scale Air Quality (CMAQ v4.7.1) model simulations, using three available biogenic isoprene emission inventories over East Asia: i) GEIA, ii) MEGAN and iii) MOHYCAN. From this comparative analysis, the tropospheric HCHO columns from the CMAQ model simulations, using the MEGAN and MOHYCAN emission inventories (Ω{sub CMAQ,} {sub MEGAN} and Ω{sub CMAQ,} {sub MOHYCAN}), were found to agree well with the tropospheric HCHO columns from the SCIAMACHY observations (Ω{sub SCIA}). Secondly, the propagation of such uncertainties in the biogenic isoprene emission fluxes to the levels of atmospheric oxidants (e.g., OH and HO{sub 2}) and other atmospheric gaseous/particulate species over East Asia during the two summer months was also investigated. As the biogenic isoprene emission fluxes decreased from the GEIA to the MEGAN emission inventories, the levels of OH radicals increased by factors of 1.39 and 1.75 over Central East China (CEC) and South China, respectively. Such increases in the OH radical mixing ratios subsequently influence the partitioning of HO{sub y} species. For example, the HO{sub 2}/OH ratios from the CMAQ model simulations with GEIA isoprene emissions were 2.7 times larger than those from the CMAQ model simulations based on MEGAN isoprene emissions. The large HO{sub 2}/OH ratios from the CMAQ model simulations with the GEIA biogenic emission were possibly due to the overestimation of GEIA biogenic isoprene emissions over East Asia. It was also shown that such large changes in HO{sub x} radicals created large differences on other tropospheric compounds (e.g., NO{sub y} chemistry) over East Asia during the summer months. - Highlights: • GEIA isoprene emissions were possibly overestimated over East Asia. �

Nuclear safety cooperation in Southeast Asia. Lessons from Asia's regional networks

International Nuclear Information System (INIS)

Trajano, Julius Cesar I.

2017-01-01

Debate has been ongoing among key stakeholders on whether South-east Asia should use or reject nuclear power. However, there are still significant regional concerns over nuclear safety and security in South-east Asia. As some ASEAN countries plan to pursue nuclear power, they need to create and maintain a pool of local nuclear professionals with actual relevant experience in the nuclear industry. While the IAEA does not influence a country's decision on introducing nuclear power, it supports Member States' efforts to evaluate all options towards making a knowledgeable decision. Nuclear safety is the responsibility of every nation that utilizes nuclear technology. National governments are responsible for regulations that govern how safety at nuclear facilities is maintained, as well as to reduce radiation risks, including emergency response and recovery actions. But nuclear energy has transboundary/ regional implications if nuclear safety in each member state is not strengthened. ASEAN countries share a common goal in achieving high level of public safety and confidence in nuclear and radiation related issues. Can regional cooperation help ASEAN Member-States strengthen nuclear safety? The paper examines the importance of regional cooperation on nuclear energy governance and the role of regional organisations in Asia in strengthening nuclear safety cooperation and emergency preparedness and response in Southeast Asia.

Significant influences of global mean temperature and ENSO on extreme rainfall over Southeast Asia

Villafuerte, Marcelino, II; Matsumoto, Jun

2014-05-01

Along with the increasing concerns on the consequences of global warming, and the accumulating records of disaster related to heavy rainfall events in Southeast Asia, this study investigates whether a direct link can be detected between the rising global mean temperature, as well as the El Niño-Southern Oscillation (ENSO), and extreme rainfall over the region. The maximum likelihood modeling that allows incorporating covariates on the location parameter of the generalized extreme value (GEV) distribution is employed. The GEV model is fitted to annual and seasonal rainfall extremes, which were taken from a high-resolution gauge-based gridded daily precipitation data covering a span of 57 years (1951-2007). Nonstationarities in extreme rainfall are detected over the central parts of Indochina Peninsula, eastern coasts of central Vietnam, northwest of the Sumatra Island, inland portions of Borneo Island, and on the northeastern and southwestern coasts of the Philippines. These nonstationarities in extreme rainfall are directly linked to near-surface global mean temperature and ENSO. In particular, the study reveals that a kelvin increase in global mean temperature anomaly can lead to an increase of 30% to even greater than 45% in annual maximum 1-day rainfall, which were observed pronouncedly over central Vietnam, southern coast of Myanmar, northwestern sections of Thailand, northwestern tip of Sumatra, central portions of Malaysia, and the Visayas island in central Philippines. Furthermore, a pronounced ENSO influence manifested on the seasonal maximum 1-day rainfall; a northward progression of 10%-15% drier condition over Southeast Asia as the El Niño develops from summer to winter is revealed. It is important therefore, to consider the results obtained here for water resources management as well as for adaptation planning to minimize the potential adverse impact of global warming, particularly on extreme rainfall and its associated flood risk over the region

Pleistocene Palaeoart of Asia

Directory of Open Access Journals (Sweden)

Robert G. Bednarik

2013-06-01

Full Text Available This comprehensive overview considers the currently known Pleistocene palaeoart of Asia on a common basis, which suggests that the available data are entirely inadequate to form any cohesive synthesis about this corpus. In comparison to the attention lavished on the corresponding record available from Eurasia’s small western appendage, Europe, it is evident that Pleistocene palaeoart from the rest of the world has been severely neglected. Southern Asia, in particular, holds great promise for the study of early cognitive development of hominins, and yet this potential has remained almost entirely unexplored. Asia is suggested to be the key continent in any global synthesis of ‘art’ origins, emphasising the need for a comprehensive pan-continental research program. This is not just to counter-balance the incredible imbalance in favour of Europe, but to examine the topic of Middle Pleistocene palaeoart development effectively.

Effect of anthropogenic sulphate aerosol in China on the drought in the western-to-central US

Yeh, Sang-Wook; Park, Rokjin J.; Kim, Minjoong J.; Jeong, Jaein I.; Song, Chang-Keun

2015-09-01

In recent decades, droughts have occurred in the western-to-central United States (US), significantly affecting food production, water supplies, ecosystem health, and the propagation of vector-borne diseases. Previous studies have suggested natural sea surface temperature (SST) forcing in the Pacific as the main driver of precipitation deficits in the US. Here, we show that the aerosol forcing in China, which has been known to alter the regional hydrological cycle in East Asia, may also contribute to reducing the precipitation in the western-to-central US through atmospheric teleconnections across the Pacific. Our model experiments show some indications that both the SST forcing and the increase in regional sulphate forcing in China play a similar role in modulating the western-to-central US precipitation, especially its long-term variation. This result indicates that regional air quality regulations in China have important implications for hydrological cycles in East Asia, as well as in the US.

The Exhumation of the Central Lhasa, Tibet: Evidence from the Low-temperature Thermochronology

Science.gov (United States)

Sun, G.; Xiumian, H.; Sinclair, H. D.; Stuart, F. M.

2017-12-01

The modern Tibetan Plateau has an average elevation of 4500 m above the sea level. But its early growth history still remains debate, despite its significance to the global climate system. In common, the early growth of the Tibetan Plateau has been attributed to the India-Asia collision in the early Paleocene. However, the structural reconstruction, Late Cretaceous sedimentation, and petrology studies, imply there would be a paleo-plateau or the high-elevation gain in the Lhasa terrane prior to the India-Asia collision. In order to examine this model, the zircon/apatite U-Th-He (ZHe and AHe) and apatite fission track (AFT) are employed to the mid-Cretaceous granites in Coqen area, central Lhasa. Eight samples from the plateau surface yield ZHe ages ranging from 88 to 54 Ma, while the AHe ages ranging from 70 to 45 Ma. Five samples from the above have been conducted the AFT analysis and yielded AFT ages ranging between 73 and 62 Ma, showing the similar age ranges with the corresponding AHe ages. Single-sample inverse thermal kinetic modeling reveal that these intrusive rocks have undergone the rapid cooling history since 85 Ma, after when, the relatively slow cooling process has been established at 45 Ma. Inverse thermal-kinetic modeling of these data, recorded in the context of the Late Cretaceous rapid cooling history, is best interpreted by the early plateau growth in the central Lhasa. In consideration of the substantial crustal thickening and shortening in the Lhasa terrane during the Cretaceous, this Late Cretaceous-Early Paleogene rapid cooling history reveal that the exhumation of the central Lhasa has initiated before the India-Asia collision. This scenario is consistent with a 30 Ma ( 90-60 Ma) sedimentation hiatus since the Late Cretaceous terrestrial conglomerate deposition in the central Lhasa terrane.
