Using political ecology as its conceptual framework,this paper focuses on the changes in forest utilisation and management of South Kyrgyzstan’s walnut-fruit forests over the last century. The aim of this study on human-environment interactions is to investigate the relationship between actors on the one side,their interests and demands,and the forests and forested lands on the other. Forest resource utilisation and management — and even the recognition of different forest products as resources — are connected with political and socio-economic conditions that change with time. The walnut-fruit forests of South Kyrgyzstan are unique,characterised by high biodiversity and a multiplicity of usable products;and they have been utilised for a long time. Centralised and formal management of the forests started with the Russian occupation and was strengthened under Soviet rule,when the region became a part of the USSR. During this era,a state forest administration that was structured from Moscow all the way down to the local level drew up detailed plans and developed procedures for utilising the different forest products. Since the collapse of the Soviet Union,the socio-political and economic frame conditions have changed significantly,which has brought not only the sweeping changes in the managing institutions,but also the access rights and interests in the forest resources. At present,the region is suffering from a high unemployment rate,which has resulted in the forests’ gaining considerable importance in the livelihood strategies of the local population. Political and economic liberalization,increased communication and trans-regional exchange relations have opened the door for international companies and agents interested in the valuable forest products. Today,walnut wood and burls,walnuts,wild apples and mushrooms are all exported to various countries in the world. Scientists and members of various international organisations stress the ecological value of the forests and are trying to establish nature conservation areas. Nevertheless,it is to fear that a multiplicity of interrelated factors — the present transformation and globalization processes,the appearance of new actors,the local population’s insecure economic situation and the erosion of managing institutions — are all leading to an intensified and unregulated exploitation of the forests,resulting in their degradation. 展开更多

In this study, tree-ring width data of Schrenk spruce (Picea schrenkiana) from the upper timberline of the Tien Shan (Kyrgyzstan) were analyzed to investigate the effect of climate change. Growtheclimate response analyses revealed that the tree rings of spruce at the upper timberline of the Tien Shan also can provide hydrometeorological (precipitation and streamflow) signals. Tree-ring records from both Kyrgyzstan and Xinjiang exhibited similar tree-growth variability at both annual and decadal time scales during the common period 1457e2009. In Xinjiang and Kyrgyzstan, tree growth was reduced during the Little Ice Age (LIA); however, the timing and magnitude of LIA differ between the two regions. During 1470e1660, the two chronologies diverged, and this phenomenon is considered to be caused by a different response to the harsh climate of the LIA. In this study, the tree-ring width series from the upper tree line of the Tien Shan is negatively associated with temperature. As opposed to previous studies, the tree-ring width series from the upper timberline of the Tien Shan appears to respond well to hydrometeorological factors. Therefore, we highlight the need for more detailed ecophysiological response studies for spruce trees at the upper timberline of the Tien Shan, in particular, with regard to the role of water availability and temperature during the growth season. 展开更多

The Tian Shan Orogenic Belt, which is a subsidiary of the Central Asian Orogenic Belt, is the largest accretion area of continental crust on the Earth during the Phanerozoic. It has experienced several accretionary processes during the Palaeozoic period and has attracted much concern among geologists. An Early Palaeozoic intrusive rock belt extends for 1000 km from east to west, occupying about 40% of the total area within the Kyrgyz Northern Tian Shan Orogenic Belt. Previous studies show that the petrology of these rocks is similar, consisting of granites and granodiorites. 展开更多

However, there is still no consensus if this is indeed the case. Blueschist, eclogite and ophiolite are present in the Atbashi Range, Kyrgyzstan, which are believed to be the relics of the Southern Tianshan Ocean. New data obtained through Ar-Ar isotopic analysis in this research provide reliable chronological restrictions for this problem. 展开更多

Background:Post-Soviet Kyrgyzstan has experienced a major surge in blood-borne infections,but data from adequately powered,up-to-date studies are lacking.We thus examined a)the seroprevalences of hepatitis B virus surface antigen(HBsAg),HIV-1 p24 antigen and antibodies against hepatitis C virus(anti-HCV),human immunodeficiency viruses(anti-HIV-1/2,HIV-1 group O),and Treponema pallidum among blood donors in Kyrgyzstan and assess their distribution according to sex,age,and provinces of residence;b)trends in the respective seroprevalences;and c)co-infection rates among the pathogens studied.Methods:Serological screening was performed on 37165 blood donors at the Republican Blood Centre in Bishkek,Kyrgyzstan,between January 2013 and December 2015.We applied poststratification weights to control for sampling bias and used logistic regression analyses to examine the association of seropositivity and co-infections with sex,age,provinces of residence,and year of blood donation.Results:Twenty nine thousand and one hundred forty-five(78%)donors were males and 8020(22%)were females.The median age was 27 years(range:18-64).The prevalences of HBsAg,anti-HCV,HIV(p24 Ag and anti-HIV),and anti-T.pallidum were 3.6%(95%CI:3.4-3.8%),3.1%(3.0-3.3%),0.78%(0.69-0.87%),and 3.3%(3.1-3.5%),respectively.Males were more likely to be seropositive for HBsAg than females(OR:1.63;95%CI:1.40-1.90),but less likely to be seropositive for anti-HCV(0.85;0.74-0.98)and HIV(0.65;0.49-0.85).Prevalences were lower in the capital than in the other provinces.There was a decreasing trend in the seroprevalences of HBsAg,anti-HCV,and anti-T.pallidum from 2012 to 2015(P-value for trend,P=0.01,P<0.0001,P<0.0001,respectively),while the seroprevalence of HIV increased(P=0.049).One hundred eighty donors(0.48%)were seropositive for multiple infections.The highest co-infection rate was observed between anti-T.pallidum and HBsAg(6.0%),followed by anti-HCV and anti-T.pallidum(5.2%),and HIV and anti-HCV(4.9%).Conclusions:The data suggest that Kyrgyzstan can be reclassified from high to lower-intermediate HBsAg endemicity,whereas the high HIV prevalence with a rising trend is an alarming finding that needs to be urgently addressed by public health authorities.The observed co-infections suggest common risk factors but also common preventive interventions. 展开更多

This article explores the new political subjectivities that are emerging in disadvantaged communities in Kyrgyzstan following post-Soviet state transformation and retreat.It explores the ways in which the collapse of the Soviet-era bureaucracy and emergence of a marketising yet rent-seeking state bureaucracy has facilitated the emergence of‘active citizens’in self-built shanty towns in two locations in Kyrgyzstan-the capital,Bishkek,and the Issyk Kul resort region in the east.Based on participant observation and research interviews with members of so-called‘selfhelp groups’in post-Soviet Kyrgyzstan,in which residents coorganise to lobby local government for basic amenities and pool funds to raise money for community infrastructure and services in the absence of a functioning state,the paper makes two contributions to understanding the nature of citizenship in the context of weak,post-Soviet states.First,it suggests that,rather than seeing self-organised citizens as a threat to stability-a perspective common to non-liberal governments-these initiatives are supported and encouraged by the Kyrgyz authorities,since they perform tasks and provide services in lieu of the weak state.Autonomous citizens who can take responsibility for their own welfare are useful when the state cannot provide adequate services.Hence,leaders of weak states are able to recontextualise global neoliberal discourses of active citizenship,which emphasise autonomous,rational citizens,in order to legitimise their functional inabilities.Second,it seeks to problematise the binary distinction between the‘passive Soviet citizen’and the modern,post-Soviet active citizen,evident in government and international NGO discourses,and suggests that the idea of the‘passive Soviet citizen’is a discursive trope utilised to distinguish desirable from undesirable subjectivity in the post-Soviet market state. 展开更多
