Glacioclimatological research in the central Tien Shan was performed in the summers of 1998 and 1999 on the South Inilchek Glacier at 5100 - 5460 m. A 14.36 m firn-ice core and snow samples were collected and used for stratigraphic, isotopic, and chemical analyses. The firn-ice core and snow records were related to snow pit measurements at an event scale and to meteorological data and synoptic indices of atmospheric circulation at annual and seasonal scales. Linear relationships between the seasonal air temperature and seasonal isotopic composition in accumulated precipitation were established. Changes in the delta(18)O air temperature relationship, in major ion concentration and in the ratios between chemical species, were used to identify different sources of moisture and investigate changes in atmospheric circulation patterns. Precipitation over the central Tien Shan is characterized by the lowest ionic content among the Tien Shan glaciers and indicates its mainly marine origin. In seasons of minimum precipitation, autumn and winter, water vapor was derived from the arid and semiarid regions in central Eurasia and contributed annual maximal solute content to snow accumulation in Tien Shan. The lowest content of major ions was observed in spring and summer layers, which represent maximum seasonal accumulation when moisture originates over the Atlantic Ocean and Mediterranean and Black Seas.

Parasites and pathogens are apparent key factors for the detrimental health of managed European honey bee subspecies, Apis mellifera. Apicultural trade is arguably the main factor for the almost global distribution of most honey bee diseases, thereby increasing chances for multiple infestations/infections of regions, apiaries, colonies and even individual bees. This imposes difficulties to evaluate the effects of pathogens in isolation, thereby creating demand to survey remote areas. Here, we conducted the first comprehensive survey for 14 honey bee pathogens in Mongolia (N = 3 regions, N = 9 locations, N = 151 colonies), where honey bee colonies depend on humans to overwinter. In Mongolia, honey bees, Apis spp., are not native and colonies of European A. mellifera subspecies have been introduced ~60 years ago. Despite the high detection power and large sample size across Mongolian regions with beekeeping, the mite Acarapis woodi, the bacteria Melissococcus plutonius and Paenibacillus larvae, the microsporidian Nosema apis, Acute bee paralysis virus, Kashmir bee virus, Israeli acute paralysis virus and Lake Sinai virus strain 2 were not detected, suggesting that they are either very rare or absent. The mite Varroa destructor, Nosema ceranae and four viruses (Sacbrood virus, Black queen cell virus, Deformed wing virus (DWV) and Chronic bee paralysis virus) were found with different prevalence. Despite the positive correlation between the prevalence of V. destructor mites and DWV, some areas had only mites, but not DWV, which is most likely due to the exceptional isolation of apiaries (up to 600 km). Phylogenetic analyses of the detected viruses reveal their clustering and European origin, thereby supporting the role of trade for pathogen spread and the isolation of Mongolia from South-Asian countries. In conclusion, this survey reveals the distinctive honey bee pathosphere of Mongolia, which offers opportunities for exciting future research.

The goal of this publication is to attempt to assess the thirteen years (2001- -2014) of the West’s military presence in the countries of post-Soviet Central Asia, closely associated with the ISAF and OEF-A (Operation Enduring Freedom – Afghanistan) missions in Afghanistan. There will also be an analysis of the actual challenges for the region’s stability after 2014. The current and future security architecture in Central Asia will also be looked at closely, as will the actual capabilities to counteract the most serious threats within its framework. The need to separately handle the security system in Central Asia and security as such is dictated by the particularities of political situation in the region, the key mechanism of which is geopolitics understood as global superpower rivalry for influence with a secondary or even instrumental role of the five regional states, while ignoring their internal problems. Such an approach is especially present in Russia’s perception of Central Asia, as it views security issues in geopolitical categories. Because of this, security analysis in the Central Asian region requires a broader geopolitical context, which was taken into account in this publication. The first part investigates the impact of the Western (primarily US) military and political presence on the region’s geopolitical architecture between 2001 and 2014. The second chapter is an attempt to take an objective look at the real challenges to regional security after the withdrawal of the coalition forces from Afghanistan, while the third chapter is dedicated to analysing the probable course of events in the security dimension following 2014. The accuracy of predictions time-wise included in the below publication does not exceed three to five years due to the dynamic developments in Central Asia and its immediate vicinity (the former Soviet Union, Afghanistan, Pakistan, Iran), and because of the large degree of unpredictability of policies of one of the key regional actors – Russia (both in the terms of its activity on the international arena, and its internal developments).

Between 2003 and 2014 the European Union’s (EU) Border Management Programme in Central Asia was implemented by the United Nations Development Programme (UNDP). However, the latter’s implementing responsibilities have just come to an end, with the next phase of the programme to be implemented by an EU member state consortium. This paper seeks to explain why the EU chose the UNDP to implement the programme in the first place; why the programme was redelegated to the UNDP over successive phases; and why, in the end, the EU has opted for a member state consortium to implement the next phase of the programme. The paper will draw on two alternative accounts of delegation: the principal-agent approach and normative institutionalism. Ultimately, it will be argued that both the EU’s decision(s) to delegate (and redelegate) implementing responsibilities to the UNDP, and its subsequent decision to drop the organisation in favour of an EU member state consortium, were driven for the most part by a rationalist ‘logic of consequentiality’. At the same time, a potential secondary role of a normative institutionalist ‘logic of appropriateness’ – as a supplementary approach – will not be discounted.

Do realizacji niemieckich interesów w polityce zagranicznej, bezpieczeństwa i gospodarczej RFN wykorzystuje instrumenty soft power z obszaru dyplomacji publicznej, polityki rozwojowej, kulturalnej i naukowej. Budowanie sieci kontaktów i lobbing polityczny, programy współpracy rozwojowej oraz zagranicznej polityki kulturalnej i naukowej, mają służyć wspieraniu niemieckiej gospodarki uzależnionej od eksportu, uzyskaniu statusu europejskiego ośrodka technologii i innowacji oraz zwiększeniu wpływu RFN na działania zewnętrzne UE. Jednym z priorytetowych obszarów stosowania tych instrumentów są dla Niemiec państwa Europy Wschodniej, Kaukazu Południowego i Azji Centralnej. Decydują o tym bliskość geograficzna i otwierające się rynki zbytu, konieczność modernizacji gospodarek tych krajów, zagrożenia dla „miękkiego” bezpieczeństwa RFN oraz rozwój relacji UE z tymi państwami. Niemiecka aktywność jest w tych krajach niezależna od sytuacji politycznej i stanowi długofalową strategię ugruntowującą pozycję RFN jako ich najważniejszego europejskiego partnera gospodarczego i politycznego.
