Natural resource potential of northern regions: methodological characteristics of comprehensive assessment

The economic assessment of renewable natural resources remains a relevant and as yet unresolved problem. Today, the economic assessment of natural resources is viewed as one of the priority tasks in the state strategy for environmental management. To a large extent, such economic assessment has become relevant following the development of market relations in Russia that require the valuation of natural resource potential. In Russia, the state cadastral appraisal of natural resources, which is already continuing for a second decade, serves as the basis to calculate the land tax for individual categories of land and does not allow making a comprehensive assessment of natural resource potential. This article expands the concept of economic assessment, describes the practice of its implementation in northern regions. It examines the traditional methodological approaches to economic assessment that are used today, such as the cost approach and its modi cations, rental income approach, market approach, alternative approach, as well as the methodological approaches based on the results of sociological studies, which have become more widespread recently. The recommendations put forward by the authors with regard to the economic assessment provide for consistency in its implementation based on a results-driven approach that ensures the comparability of calculations and improves the reliability of obtained results. The methodological approaches proposed for assessing the land, forest, hunting, fishery and biological resources of wild plants allow considering the specific characteristics of northern territories and implementing a comprehensive economic assessment of the region’s natural resource potential. The authors consider the expediency of calculating the unit value index of natural resource potential in order to rank the areas within the subject of the Russian Federation in proportion to the investment in the projects aimed at developing the natural resources. The methodological recommendations have been tested in the context of Berezovsky municipal district of Khanty-Mansi Autonomous Area—Yugra.The article has been prepared with the support of the Grant No. 14–18–00456 Substantiating the Geo-Eco-Socio-Economic Approach to the Development of Strategic Natural Resource Potential of Northern Understudied Territories as Part of the Investment Project The Arctic—Central Asia provided by the Russian Science Foundation

Methodological Toolkit for Assessing the Investment Attractiveness of Renewable Resources in Northern and Arctic Territories

This article examines a pressing issue of assessing the investment attractiveness of renewable resources in underdeveloped Northern and Arctic territories that have a huge untapped natural resource potential. The subject of the study is the economic interactions that occur during the development of natural resource potential. The goal of this study is to develop the methodological toolkit for assessing the investment attractiveness for businesses and government authorities at various levels. At the pre-investment stage of development projects, we identified typical landscapes for zoning of the territory and assessed them for each type of renewable natural resources. Based on an analysis of existing approaches to natural resource zoning, the authors propose to identify three types of landscapes, including those that are attractive in terms of investment, those that are attractive in terms of investment with certain limitations, and those that are unattractive for investment. The study has confirmed the hypothesis that the selection of the most valuable natural resources expands the opportunities for their economic use. The investment attractiveness is determined by favorable geographical location, development of regional infrastructure, natural potential viewed as a priority object. The authors have provided the rationale for the need to valuate the natural resource potential of landscape areas within the boundaries of an assessed territory for the purposes of their ranking based on establishing the investment attractiveness. The limitations may be imposed by the low level of infrastructure development prerequisites, insufficient sustainability of landscapes to anthropogenic influences, export of raw materials for processing outside the territory, etc. The authors have substantiated the list of conditions that require the introduction of correction coefficients to the value indicators of natural resource potential in landscape areas. The main findings of the study are presented in the form of landscape zoning of the territory and methodological toolkit for assessing the investment attractiveness tested in Berezovsky Municipal District of Khanty-Mansi Autonomous Okrug—Yugra.The article has been prepared under the Grant No. 14–18–00456 "Substantiating the Geo-Eco-Socio-Economic Approach to the Development of Strategic Natural Resource Potential of Northern Understudied Territories as Part of The Arctic—Central Asia Investment Project " provided by the Russian Science Foundation

Incoherent pion photoproduction on the deuteron in the first resonance region

Incoherent pion photoproduction on the deuteron is studied in the first resonance region. The unpolarized cross section, the beam asymmetry, and the vector and tensor target asymmetries are calculated in the framework of a diagrammatic approach. Pole diagrams and one-loop diagrams with $NN$ scattering in the final state are taken into account. An elementary operator for pion photoproduction on the nucleon is taken in various on-shell forms and calculated using the SAID and MAID multipole analyses. Model dependence of the obtained results is discussed in some detail. A comparison with predictions of other works is given. Although a reasonable description of many available experimental data on the unpolarized total and differential cross sections and photon asymmetry has been achieved, in some cases a significant disagreement between the theory and experiment has been found. Invoking known information on the reactions $\gamma d\to\pi^0 d$ and $\gamma d\to np$ we predict the total photoabsorption cross section for deuterium. We find that our values strongly overestimate experimental data in the vicinity of the $\Delta$ peak.Comment: 22 pages, 23 figure

Calculating extrusion textures of the alloy Mn-AI-C

The alloy Mn-Al-C (magnetic z-phase) has a face-centered tetragonal lattice* with the superstructure L10 (Shangurov, Gornostyrev, Teitel et al., 1990). The tetragonal crystal axes c (the directions of the easy magnetization) of the grain lattices of the polycrystal permanent magnet must be preferably oriented along the magnet axis. In the present paper the forming of the axial extrusion textures in the alloy Mn-Al-C is investigated theoretically. The texture inhomogeneity is taken into account by solving the boundary value problem of plasticity

Tendencies in current climate change and atmospheric circulation variability in the Arctic region of West Siberia

The main goal of this study is to carry out the investigation of the climatic parameters variability and the role of global atmospheric circulation in their trends over the Arctic region of West Siberia (60-70°N, 60-90°E) using reanalysis data. The characteristics of spatial and temporal variability of meteorological parameters (surface air temperature and soil temperature, atmospheric pressure, snow depth and surface albedo) were calculated using ERA-Interim reanalysis data over the period of 1979−2015. It was established that in the beginning of XXI century, there is an air and soil temperature decrease in winter and autumn and its statistically significant increase in spring and summer. The tendency to permafrost area degradation is observed for the Arctic region. The maximal changes are observed in low-temperature permafrost soils than in soils with higher temperature. This trend is accompanied by the decrease in snow cover depth and surface albedo. Global circulation indices variability, its relationships with meteorological parameters in West Siberia and with sea ice cover extent in the Arctic Seas indicate that atmospheric blocking processes, which are responsible for anticyclonic type of weather, were developed in the region during last decades
