This article presents a dataset for calculating the index of inclusive growth in the regions of the Russian Federation, estimated on key and institutional foundations of the performance of inclusive development. The authors of the research used the methodology of the World Economic Bank and the World Economic Forum, based on a comparative analysis of key and institutional indicators of the performance of territorial entities, which they adapted to the socio-economic features of the regional division of Russia. For the purpose of formation of a dataset was executed assessment of the inclusive growth index for 26 regions of the Russian Federation, it allowed to define the strengths and weaknesses of the inclusive development of each region of the Russian Federation. The dataset can be useful in the formation of strategic programs of inclusive development.

Global warming has begun to affect Yakutia, an area recognized as the coldest region of the Northern Hemisphere. Previous research has indicated that the effects of global warming will be long-term. When modeling oncoming climatic changes, researchers often forecast the related water flow changes in various water bodies as well. However, these evaluations frequently differ from the actual water flow data. Thus, the current study identifies and assesses the trends in long-term flow fluctuations in the current context of global warming. This is particularly relevant in the subarctic region of Yakutia, because the local climate is not significantly influenced by anthropogenic factors. The region has an essentially uniform climate, and the river basins within the subarctic zone flow in the same direction. Thus, the study parameters can be adequately compared. Analysis of changes in the water regimen parameters of the rivers in this region is of particular importance. This study demonstrates that the changes in the long-term river regimen in the region, within approximately equivalent climate zones, have been highly and locally variable indifferent areas and time periods. However, we were unable to detect any specific consistency in these changes. The water content of almost all rivers in Yakutia has increased in the last 30 years (approximately), thus confirming general assumptions based on predictive models of climate changes; however, in most cases, such changes were the result of reaching the high-water stage of established long-term cycles. The nature of long-term fluctuations in the water flow of rivers did not change in about half of the Yakutia rivers. One water body showed a further decrease in the water content from the norm, both in terms of duration and water flow rate. Meanwhile, specific water bodies exhibited extreme long-term fluctuations, which are predicted to be a reaction to global warming. Prior to the onset of significant warming in the region, the trends of long-term water discharge fluctuations were stationary. Then, the trends of certain rivers became non-stationary due to the reasons indicated above. On their own, quantitative characteristics are insufficient to evaluate actual changes in water regimens. Moreover, evaluations obtained in the absence of a trend analysis of specific long-term discharge fluctuations, which can only be performed via graphic visualization, are most likely to be inaccurate.

Currently, not only the expected future climatic changes but also the associated changes in the long-term waterflow regime are popular research objectives. However, such studies, as a rule, are focused on large water bodies of a regional or even subplanetary significance. Also, the estimates obtained for the expected changes in the waterflow regime are of the most common nature. They are certainly important in terms of assumptions on the main trends in the development of the situation with water resources on a macro-regional scale but do little in assessing the risks of water use or even living safety (if people live near a water body) in the foreseeable future in respect of relatively small and medium-sized water bodies. The study identifies and evaluates the specifics of the waterflow regime response to global warming for rivers, the basins of which are compactly located within a single natural and climatic zone - the middle part of Yakutia. This approach allows adequately comparing the parameters of changes in the behavior of long-term waterflow variations for different rivers. For all rivers in the middle part of Yakutia, a significant increase in water content has been detected after 1987 (taken as the year preceding the start of the climate warming period), however, for the rivers of the western part of the region, this increase is associated not with a change in the behavior of long-term waterflow variations but with the onset of a high-water phase of a long-term natural cycle there. An increase in the annual waterflow variations was recorded for almost all rivers. Changes in the behavior of long-term waterflow variations after 1987 led to the loss of stationarity of the annual waterflow time series in the overwhelming majority of cases. It has been established that for rivers located in the middle part of Yakutia, a change in the behavior of long-term waterflow variations, which is presumably associated with global warming, can manifest itself in two main forms: a) in some cases, extremely high annual waterflow against the background of the typical regime of long-term variations - 1-2 cases (for the period from 1987 to 2018) lasting 1-3 years; b) the onset of a relatively long (5 years or more) period with an increased annual water content against the background of a violated of the cyclical behavior of long-term water content variations, which is typical for a given river. Herewith, for the rivers of the western region zone, the absence of pronounced changes in the behavior of long-term waterflow variations has been detected.

Studies of long-term fluctuations of the river flow are of interest with regard to causal relationships and associations between the climate changes and water regimen of the rivers. It is important to minimize the negative effects associated with fluctuations in the river flow based on long-term predictions of the water contents. Long-term and very long-term predictions of the water contents require understanding of the nature of the long-term changes in the water contents of the rivers. Investigation of the spatial trends in changes in the river water contents is important. It was established that there was an increasing straight-line trend of change in water content for the majority of the rivers on the territory of the Republic of Sakha (Yakutia) during the period from 1964 till 2015. Mapping of the slope factor of the linear trends allowed to determine the main regularities of the spatial breakdown of the type of perennial change in river flows. Besides, smoothing of the time series of the river flow by the method of 20–year sliding linear trend in a span of twenty years allowed to establish the types of perennial change in water content for each water body with further zoning.
