Our article focuses on the essence, characteristics, and the structure of the labor potential of the region as well as its role in socio-economic development, territorial and environmental characteristics of labor resources and mechanisms for the reproduction of labor potential. Our results are based on a conceptual and methodological review of foreign and domestic sources. Perspective directions of labor resources research manifest such common features as the assessment of migration risks, the influence of globalization factors, forecasting the dependence of labor productivity at the regional level on market factors, climatic conditions, insurance mechanisms, and other factors. We conclude that research activity directed at human resources of the regions and their qualitative and quantitative properties is extremely high. Moreover, we note a high level of interest of scientists to the problem of labor potential at the micro, meso and macro level in Russian Federation. Our paper pays special attention to the analysis of existing approaches to methods for assessing the labor potential of the region, as proposed by Russian researchers and applied in the Russian Federation. Moreover, it considers the features of the main methodological approaches, studies their classification, as well as the technology of evaluation depending on the research tasks and objectives. We describe the method used for measuring the labor potential of a region on the basis of the index method which allows us to take into account its specific conditions of its reproduction and use at the regional level, as well as to conduct reasonable comparative assessments. In addition, we present our own calculations carried out on the basis of the proposed method and employing the state and the level of development of labor potential in the North Caucasus and Southern Caucasus federal districts, as well as in the Russian Federation as a whole.

This study aims at improving our understanding of observed runoff changes in two glacier covered headwater catchments of the Tarim River in north-west China over the last 50 years, as well as at assessing possible future changes of glaciers and the water balance due to climate change. To this end, we applied an approach based on hydrological modeling. In order to increase the robustness of the results, the model was calibrated in a multi-objective way using daily runoff data, long-term runoff trends, and glacier mass balance data. The results show that the runoff increase over the last 50 years is to a large extent due to an increase in air temperature and an associated increase in glacier melt. Simulations with climate scenarios indicate a further temperature-induced increase of glacier melt in the beginning of the 21st century, but then glacier melt declines due to decreasing glacier areas. Decreasing glacier melt and increasing evapotranspiration result, despite projected increases in precipitation, in decreases of total discharge in 2070-2099 compared to 1971-2000. Целью данного исследования является анализ наблюдаемых изменений стока в двух горно-ледниковых бассейнов р. Тарима на северо-западе Китая за последние 50 лет, а также оценка возможных будущих изменений ледников и водного баланса, вызванные изменением климата. Для этой цели использовалась гидрологическая модель. Чтобы повысить надежность результатов, модель была откалибрована многоцелевым методом на основе ежедневных данных расходов воды, долгосрочных трендах и балансе массы ледников. Результаты показывают, что увеличение расходов за последние 50 лет во многом связано с увеличением температуры и связынным с этим усилением таяния ледников. Моделирование по климатическим сценариям показывает сперва дальнейшее увеличение талого стока связанного с повышением температуры в XXI веке, однако в дальнейшем с уменьшением ледниковой массы, результаты указывают на значительное снижение ледникового стока. Вместе с увеличением испарения это приводит к уменьшению общего расхода в 2070-2099 гг. по сравнению с 1971-2000 гг.
