Shallow geothermal energy (SGE) is a promising green and sustainable energy source, gaining prominence in light of the dual-carbon target. This study investigated the SGE resources in the Yinchuan area. Suitability zones and the potential of SGE resources were determined based on the comprehensive analysis about thermophysical parameters, hydrogeological conditions, and geological environment. Our findings revealed that the effective thermal conductivity in the Yinchuan area surpasses those of other cities, indicating significant potential for SGE. The thermostat layer depth ranges from 40 to 60 m, with a geothermal gradient between 0.81 and 6.19 °C/100 m. Regions with poor adaptability for a borehole heat exchanger (BHE) are mainly distributed in the western and southern parts of the Yinchuan area, whereas moderately and highly adaptable areas are primarily located in the central and eastern areas, respectively. The total geothermal resource of the BHE in the Yinchuan area amounts to 1.07 × 108 GJ/a, generating significant economic benefits of 1.07 × 109 CNY/a and saving 1.09 × 106 t/a of standard coal annually. This initiative leads to significant reductions in CO2, SO2, and NOx emissions by 2.61 × 106 t/a, 1.86 × 104 t/a, and 6.57 × 103 t/a, respectively. Additionally, it results in potential savings of 0.309 × 109 CNY/a in environmental treatment costs. The methods and models used in this study have potential for similar geothermal surveys in arid and cold regions. The results also contribute essential insights for policy formulation and sustainable development strategies related to shallow geothermal resources in the Yinchuan area. [ABSTRACT FROM AUTHOR]

Abstract This article investigates the interrelationships and interdependencies inherent in the integrated use of the territory’s social, resource, and environmental potential to achieve its sustainable development. The basic hypotheses formulated during this study were as follows: Sustainable development of the territory’s resource and ecological potential cannot be achieved if its social potential is reduced; Sustainable development of the territory’s ecological and social potential can be achieved only if it is economically feasible, that is if it contributes to the sustainable development of the territory’s resource potential; Sustainable development of the territory’s resource and social potential cannot be achieved while its ecological potential deteriorates; Ensured sustainable development of territories in today’s world is only possible with simultaneous integrated use of the territory’s social, resource, and environmental potential. The aim of this research is to investigate the interrelationships among these three components and to determine their impact on the overall development of the regions. A comprehensive multi-stage research project based on the analysis of statistical information and survey results was designed and applied to meet the research objective. Methodologically, the study was based on a quantitative approach, which led to the integrated use of economic-statistical and econometric data processing methods. All these hypotheses were tested and found to be true in the Kizilsu Kyrgyz Autonomous Prefecture of the People’s Republic of China. The results indicate a direct and stable relationship between the development of resource potential, ecological potential, and social potential of the territories. Specifically, regions with high resource potential exhibit better social indicators, while ecological investments contribute to the improvement of public health and quality of life. The originality of this study lies in its comprehensive approach to examining the interconnections among resources, social aspects, and ecological sustainability, thereby contributing to the international literature in the field of sustainable development. These results can be of use to state and municipal government experts when planning territorial development, as well as to academic researchers, including to identify promising avenues for later research.

Helium is a globally scarce strategic resource that is relevant to national economies and the development of high-tech industries, and China primarily depends on imported helium for its industrial applications. Therefore, there is an urgent demand for clarifying helium formation and enrichment patterns, searching for helium-rich fields, and realizing China's helium resource inventory and development potential. This article analyzes the reservoir characteristics and accumulation conditions of typical helium-rich fields in China, and clarifying the origin and source of helium as well as the main controlling factors of helium enrichment. It was recognized that helium in natural gas in China mainly comes from crustal sources. Relatively shallow buried ancient U–Th-rich granite basement or intrusion, large and stable ancient uplift or submarine formed in the early period, good overburden of huge thick paste-salt rock or mudstone cover, and channels connecting the basement and reservoir, were the main controlling factors of helium enrichment. Four types of helium-rich gas reservoirs, namely helium-rich conventional gas, helium-rich shale gas, helium-rich non-hydrocarbon gas, and helium-rich water-soluble gas, have been modeled and predicted to be helium-rich favorable exploration areas. Based on this analysis, the prospect of helium resource development in China has been analyzed. It was proposed that the exploration of helium-rich fields and the comprehensive development and utilization of medium- and low-abundance helium resources are important ways to increase the domestic helium production in China in the future.

The Da'anzhai Member of the Lower Jurassic in northern Sichuan Basin is one of the major oil-bearing formations in the basin. In recent years, with the development of unconventional exploration theories, exploration efforts have shifted towards the shale reservoirs in the Da'anzhai Member, enhancing the understanding of the exploration directions for continental shale oil in northern Sichuan. Based on the data from shale oil exploration wells LY1 and YY2, including core samples, experiments, drilling, and fracturing data, a reassessment of the oil and gas formation conditions, resource potential, and engineering geological conditions was conducted. The results indicate that: (1) The second submember of the Da'anzhai Member in Langzhong has a good resource base and formation conditions, indicating great exploration potential. The second submember mainly develops three lithologies: shale, shell limestone, and shale interbedded with shell limestone. The shale exhibits good hydro- carbon source quality and is generally in a middle to high-mature stage. Its hydrocarbon production intensity is (20-90)×104 t/km2, and the retained hydrocarbon accounts for 66% to 78% of the total hydrocarbon production, with a shale oil resource amounting to 3.26×108 t. (2) The shale samples from the second submember in the study area have poorly developed fracture networks, characterized by poor permeability conditions, difficult drilling and compressibility conditions. The matrix-type shale oil has high crude oil viscosity and high wax content. The coupling configuration relationship between the permeability of the shale samples and the fluidity of the shale oil is key to achieving high production in target layers. (3) Given the current poor production results in matrix-type shale exploration, it is recommended to adopt a combined conventional and unconventional exploration method to study the formation system of the shale and limestone interlayer reservoirs in the research area, considering high-quality shale and fracture-porosity type limestone as favorable exploration targets. Through the integration of geological and engineering research methods, efforts should be made to tackle technical challenges related to drillability, compressibility, and production, thereby improving engineering and technological levels.

The article presents the authors’ vision of the emerging geopolitical factors determining Russia’s position in the global energy infrastructure, which allowed identifying problems and defining priorities and directions of spatial organization of the Arctic system of energy transport communications, expanding the possibilities of involvement of highly liquid energy resources of the Russian Arctic into active economic turnover. The purpose of the study is to analyze the prospects of the economic development of Arctic energy resources in the context of projected changes in the world economic order from the standpoint of ensuring the long-term energy sustainability of the national economy and strengthening Russia’s position in the energy markets of the Asia-Pacific region. The data presented in the study show the vulnerability of the current export-oriented model of the resource-raw materials economy in Russia due to technological and infrastructural limitations of transport logistics. The study substantiates the need to form a new world-system infrastructure for the country’s energy security using the natural resource potential and geo-economic advantages of the Arctic territories. This implies the involvement of highly liquid reserves of fossil energy resources in the Arctic into active economic turnover through the creation of mineral resource centers (MRCs) included in the structure of world economic fuel and energy relations. To achieve this goal, a conceptual model of spatial organization of the Arctic system of energy transport communications is proposed, which combines marine, coastal and land infrastructure facilities into intermodal energy transport corridors (IETC), opening additional opportunities for participation in global, national, interregional value chains and providing a synergetic effect of development of remote Arctic territories.

Objective China is the largest producer of rare earth element (REE) and hosts the largest amount of REE resources. Various types of REE deposits have been reported in China, with alkaline-carbonatite related light REE deposits and ion-adsorption heavy REE deposits being the most important ones. Other REE deposit types include REE placers and deposits with REE by-products. Currently, the development of rare earth resources in China is primarily focused carbonatite-alkaline related light REE deposits and ion-adsorption type heavy REE deposits. REE in placer deposits and other REE by-products have not been effectively utilized. Methods Based on existing exploration studies and whole-rock REE geochemistry data analysis, this study provides a brief review of the types and resource potential of deposits with REE by-products in China. Results China's by-products REE resource types include marine sedimentary phosphate, coal, bauxite, and magmatic iron-phosphate deposits. These deposits, particularly marine sedimentary phosphate deposits and bauxite, contain enormous potential REE resources. REEs in bauxite are primarily light REE, with some containing high amount of scandium (Sc). In sedimentary phosphate deposits, the proportion of heavy REEs (including yttrium) is high, particularly in the S−P−Al−Sr rich ores that occur as the layers overlying the phosphorite in the Shifang-type phosphate deposits of Sichuan Province. These S−P−Al−Sr rich ores have significantly higher REE content than phosphorite, with medium and heavy REE accounting for over 50%, along with various critical metals, making these ores highly valuable in terms of both resource and economic significance. Furthermore, REE resources in magmatic (iron) phosphate deposits, coal, oil shale, and gold deposits deserve attention. Conclusions Owing to the lack of detailed exploration data, the full extent of China's by-products REE resources remains unclear. The comprehensive utilization of resources, as well as the technology for REE recovery and extraction, requires improvement. Significance Strengthening the evaluation and comprehensive utilization of China's associated REE resources, particularly by fully utilizing the REE resources associated with phosphate and bauxite deposits, can effectively alleviate the pressure on China's HREE supply. This represents an important measure for implementing China's fundamental national policies on resource conservation and environmental protection.

According to the strategy for the development of the forestry complex of the Russian Federation until 2030, approved by Order of the Prime Minister of Russia no. 312r dated February 11, 2021, the contribution of the forestry industry to the country’s economy should increase by 2 times, including through deep wood processing. To this end, enterprises for deep processing of wood raw materials will be actively developed. Consequently, there will be a shortage of wood raw materials, which will lead to an urgent need to expand the raw material base of these industries. Despite this, as the analysis of the practical experience of modern logging enterprises has shown, today, during logging operations, only the stem part of the tree is removed from the cutting area, and the rest of the biomass in the form of stumpwood, branches, twigs and tops is burned or buried, although these parts of the tree are valuable raw materials for the production of many types of products of wood processing enterprises. This state of affairs is due to the lack of effective technology for processing potential raw materials in the places of their formation and a complex of mobile machines for its implementation. As a result, a technology for the production of wood and coniferous flour, technological chips and semi-finished wood-fiber products, as well as mobile equipment for its implementation, has been proposed for the processing of logging waste in the form of tops, branches and twigs. The article presents technological solutions and equipment models built in the SolidWorks computer-aided design system. The introduction of the proposed technologies, machines and mechanisms will increase the share of harvested raw materials per unit area, reduce the environmental load from the logging process, and increase the efficiency of the industry.

To reveal the enrichment conditions and resource potential of coal-rock gas in the Ordos Basin, this paper presents a systematic research on the sedimentary environment, distribution, physical properties, reservoir characteristics, gas-bearing characteristics and gas accumulation play of deep coals. The results show that thick coals are widely distributed in the Carboniferous-Permian of the Ordos Basin. The main coal seams Carboniferous 5# and Permian 8# in the Carboniferous-Permian have strong hydrocarbon generation capacity and high thermal evolution degree, which provide abundant materials for the formation of coal-rock gas. Deep coal reservoirs have good physical properties, especially porosity and permeability. Coal seams Carboniferous 5# and Permian 8# exhibit the average porosity of 4.1% and 6.4%, and the average permeability of 8.7×10-3 µm2 and 15.7×10-3 µm2, respectively. Cleats and fissures are developed in the coals, and together with the micropores, constitute the main storage space. With the increase of evolution degree, the micropore volume tends to increase. The development degree of cleats and fissures has a great impact on permeability. The coal reservoirs and their industrial compositions exhibit significantly heterogeneous distribution in the vertical direction. The bright coal seam, which is in the middle and upper section, less affected by ash filling compared with the lower section, and contains well-developed pores and fissures, is a high-quality reservoir interval. The deep coals present good gas-bearing characteristics in Ordos Basin, with the gas content of 7.5-20.0 m3/t, and the proportion of free gas (greater than 10%, mostly 11.0%-55.1%) in coal-rock gas significantly higher than that in shallow coals. The enrichment degree of free gas in deep coals is controlled by the number of macropores and microfractures. The coal rock pressure testing shows that the coal-limestone and coal-mudstone combinations for gas accumulation have good sealing capacity, and the mudstone/limestone (roof)-coal-mudstone (floor) combination generally indicates high coal-rock gas values. The coal-rock gas resources in the Ordos Basin were preliminarily estimated by the volume method to be 22.38×1012 m3, and the main coal-rock gas prospects in the Ordos Basin were defined. In the central-east of the Ordos Basin, Wushenqi, Hengshan-Suide, Yan'an, Zichang, and Yichuan are coal-rock gas prospects for the coal seam #8 of the Benxi Formation, and Linxian West, Mizhi, Yichuan-Huangling, Yulin, and Wushenqi-Hengshan are coal-rock gas prospects for the coal seam #5 of the Shanxi Formation, which are expected to become new areas for increased gas reserves and production.

Deep-sea polymetallic nodules are associated with rich rare substances, such as rare-earth elements (REEs), Mo, Ti, Te, Li, which are currently in demand and are used in various applications. Deep-sea sediments near nodules are another important source of REEs, which will increase the resource potential of polymetallic nodules. Given the similarity of the mining technologies for deep-sea REEs and polymetallic nodules, this study proposed environmentally friendly mining options and developed a technoeconomic evaluation model by combining deep-sea polymetallic nodules and REEs. Using the Clarion-Clipperton Fracture Zone as an example, this study revealed that the development of polymetallic nodules together with REEs of nearby sediments in the form of by-products will improve the economic and environmental benefits. In addition, the effects of discount rate, cost, and price on the economic benefits of nodule mining were discussed, and a technical development direction was proposed based on scientific and technological needs.

To address the global warming issue, China is prioritizing the development of clean energy sources such as wind and solar power under its "dual carbon target". However, the expansion of these resources is constrained by their intermittency and the spatial and temporal distribution of wind and solar energy. This paper systematically reviews the evolution of wind and solar energy reserves, their development potential, and their current status in China from a geographical perspective. In conjunction with existing research, this paper anticipates future exploration in the realm of wind–solar complementary development or multi-energy complementary development, viewed through the lens of resource quantity. The anticipated findings are intended to furnish a theoretical foundation for further studies on the development and utilization of wind and solar energy resources within China.

The shale of different potential layers is studied by using rock pyrolysis analysis, total organic carbon determination (TOC), kerogen microscopic component identification, mineral X-ray diffraction, scanning electron microscopy, and low-temperature nitrogen adsorption experiments. The results are as follows: (1) Shishui Formation of the Lower Carboniferous and Longtan Formation of the Upper Permian are the two most important shale gas reservoirs in the Chenlei Depression. The sedimentary environment of the target shale is a marine land interaction facies coastal bay lagoon swamp sedimentary system. Two sedimentary facies of tidal flat facies, subtidal zone, and lagoon swamp facies are developed. (2) The organic matter types of shale are Type III and II2, with TOC content greater than 1%. The maturity of shale samples is relatively higher (Ro,max is above 2%), which means they have entered the stage of large-scale gas generation. The overall brittle mineral content of the target shale sample is relatively higher (above 40%), which is conducive to artificial fracturing and fracture formation in the later stage, while an appropriate amount of clay minerals (generally stable at 40%) is conducive to gas adsorption. (3) The overall pore structure of the water measurement group and Longtan group is good, with a higher specific surface area and total pore volume (average specific surface area is 12.21 and 8.36 m2/g, respectively), which is conducive to the occurrence of shale gas and has good adsorption and storage potential. The gas content of the water measurement group and the Longtan Formation varies from 0.42 to 5 cm3/g, with an average of 2.1 cm3/g. It indicates that the water measurement group and the Longtan Formation shale gas in the study area have good resource potential. [ABSTRACT FROM AUTHOR]

Tailings generated during ore processing may host significant residual contents of valuable commodities, including critical metals. The particle properties of the tailings, such as mineralogy, particle size, and the surface liberation of ore minerals, strongly control processing behaviour. This study explores a novel combination of methods for incorporating particle data, derived from automated mineralogy, into geometallurgical models of tailings deposits to better understand their reprocessing potential and the economic feasibility of re-mining. This was achieved through binning of different particle types, geostatistical modelling of particle bin frequencies, and bootstrap resampling to reconstruct particle populations. The spatial distributions of processing-relevant particle properties throughout the tailings deposit were predicted with corresponding uncertainties. There are clear systematic trends in the spatial distributions of different particle types, resulting from the sedimentary-style deposition of the tailings. For instance, the tailings nearer the dam walls comprise coarser, silicate-rich particles, while fine-grained and well-liberated sulphide mineral particles are more abundant in the centre of the tailings deposit. As a result, robust models could be developed for the spatial distributions of particle size and mineralogy, which strongly control the sorting of particles during deposition, and other related properties, such as sulphide mineral grain sizes. Finally, a bulk sulphide flotation process was simulated and acid mine drainage potential estimated using the interpolated particle data. Around 58% of the sulphide minerals present could be recoverable by flotation, with the recoverable sulphide portion decreasing towards the centre of the TSF due to the fine-grained nature of the sulphide minerals. The acid mine drainage potential of the tailings is estimated to be moderate to high, indicating that the carbonate minerals present are not sufficient to neutralise the high acid-generating potential of the sulphide minerals. Overall, this study demonstrates how particle-based geometallurgical models can be developed and utilised for practical applications, with the aim of improving the accuracy of resource and reserve estimations of tailings deposits and the sustainable and responsible management of anthropogenic resources. The methodology proposed here can be easily transferred to other tailings deposits.

Objective Well C902, located in the Ganchaigou area of the western Qaidam Basin, achieved a breakthrough in shale oil exploration as indicated by the high-production oil flow in the Ⅳ-Ⅵ layers of the Upper Member of the Palaeogene Xiaganchaigou Formation. However, ambiguities in evaluation criteria and resource potential limit the efficiency of shale oil development in the Upper Member of the Xiaganchaigou Formation in the Ganchaigou area. Methods Thus, the exploration potential of shale oil in the Ⅳ-Ⅵ layers of the Upper Member of the Xiaganchaigou Formation in the Ganchaigou area was comprehensively evaluated by comparing the lithology, physical properties, pore structure, and organic geochemistry between Well C902 and other wells. Results The complicated lithofacies of laminar/lamellar dolostone, laminar/lamellar limestone, laminar clay shale, and lamellar mudstone suggest the mixed carbonate and siliciclastic deposition of the Ⅳ-Ⅵ layers. The high brittleness index implies the good fracability of the Ⅳ-Ⅵ layers. The intergranular pores and laminar fractures, with a total proportion of 85% in the pore system, were dominant in the Ⅳ-Ⅵ layers that can be roughly classified as low-porosity and ultralow-permeability reservoirs. The organic matter, dominated by type Ⅰ-Ⅱ1, shows an average TOC content of more than 0.9% in the Ⅳ-Ⅵ layers. Both chloroform asphalt "A" and S1+S2 indicate a high hydrocarbon generation capacity. Conclusion Summarily, the widely deposited the Ⅳ-Ⅵ layers of the Upper Member of the Xiaganchaigou Formation have the characteristic of source-reservoir integration and show not only good quality of source rock but also strong fracability of the shale oil reservoir. The excellent source-reservoir-caprock assemblage is also widely developed, which ensures good sealing ability and favors improving oil and gas recovery after fracturing. This study can theoretically improve the development efficiency of shale oil in the Ganchaigou area.

The increase in life expectancy is a global trend in the field of population. The purpose of the article is to identify the changes in the components of the resource potential of Russians belonging to different real generations but being in the same age phase of 50–69 years. The first cohort reached the age of 50–69 years in 1993, the second in 2021. Within the framework of the study, resource potential is understood as a set of significant socio-psychological, economic and personal characteristics necessary for leading an active social and everyday life. E. Rosset’s position on the lengthening of the period of adulthood with an increase in life expectancy is taken as the methodological basis of the study. The provisions of the theory of social activity and the sociological approach to personal self-sufficiency are used to identify qualitative changes in the social and personal characteristics of Russians who are at a transitional stage of their life path from maturity to old age. The research hypothesis about gradual changes in the ways of organizing life, attitudes and behavior in people in transition from adulthood to old age is tested based on a comparison of data from two studies – RUSSET, Wave 1, 1993; the National Survey of the Older Generation under the SHARE program (population 50+), 2021. The social characteristics and attitudes of respondents who are in the same age phase (50–69 years old), but belong to different age cohorts that differ by generation length, are compared. The intensity and severity of family, professional, communication, etc. differentiates life choices on a scale from “active life” to “survival”. The main result of the study was the differentiation of the components of the resource potential of the older generation into changeable and stable ones. Trends were identified that reflect qualitative changes in the resource potential of older generations of Russians. They cannot be unambiguously characterized as positive or negative. In the context of the problem of human potential, the most significant change is associated with an increase in the level of education of older Russians. Older Russians are a highly educated population with high demands on society and an active social position. The rigidity of attitudes towards retirement age and professional employment constrains the resource potential of older Russians. In conclusion, it is concluded that the results obtained during the study can serve as an additional basis for the practical implementation of tasks related to the mobilization of the human resource of older Russians.

Accelerating the exploration and development of deep ( > 1 000 m)coalbed methane (CBM) resources is an important way for the large-scale development of CBM and an important development direction in recent years. Guizhou Province is rich in CBM resources, with a large proportion of deep CBM resources. However, up to now, the geological research and exploration of deep CBM resources have not been carried out. Based on the geological background of CBM in Guizhou, this paper analyzes the geological characteristics and resource potential of deep CBM in Guizhou Province using a large number of CBM well test data. The research results show that the deep CBM resources in Guizhou are mainly distributed in many syncline units of the Liupanshui, North Guizhou and Zhina coalfields. Sedimentary differentiation and structural zoning lead to regional differences in the geological conditions of deep CBM reservoirs. The Liupanshui coalfield is characterized by “obvious overpressure, low temperature and high stress”, the Zhina coalfield is characterized by “overpressure, high temperature and low stress”, and the northern Guizhou coalfield is characterized by “overpressure, high temperature and high stress”. The permeability of deep CBM reservoir is low, and the permeability of 1 000 m deep will be generally lower than 0.1×10−15 m2. The CBM content of the coal reservoir is relatively high. The average CBM content of the middle-rank coal reservoir represented by the Liupanshui coalfield is 10.03 m3/t, and the average CBM content of the high-rank coal reservoir represented by the Zhina and Qianbei coalfields is 14.51 m3/t, and the deep supersaturation phenomenon is more obvious at 400 m. Based on the prediction model of free gas and adsorbed gas, considering the change of coal rack, it is predicted that the overall gas content in the deep part will further increase, and the supersaturation phenomenon will be more obvious, and the proportion of free gas will increase. At about 2000 m, the proportion of free gas will generally reach 10%−25%, and the proportion of free gas in medium-rank coal is higher than that in high-rank coal. On this basis, the geological resources of CBM in the key synclines of Guizhou Province with a depth of more than 2000 m are calculated. Based on the calculation results, the geological resources of CBM in Guizhou Province is 3.85 trillion m3, of which the geological resources of CBM in the depth of 1000 m reach 1.90 trillion m3, and the deep CBM resources in the Liupanshui and northern Guizhou coalfields account for a large proportion. Considering the scale and abundance of resources comprehensively, the development sequence is proposed. The Panguan-Tucheng-Zhaozihe-Jiupu'an syncline and the Gemudi syncline are the preferred development units. The above synclines are large gas fields with high abundance.

The results show that the total shallow geothermal capacity of 150m shallow rock and soil bodies in Xiongdong area is about 4.7×1012 kJ/C, the total static reserves of shallow geothermal energy are about 23.4×1012kJ, and the average resource potential of buried pipe heat transfer under summer cooling conditions is 433,000 m²/km². The average resource potential of heating conditions in winter is 859,000 m²/km². From the perspective of economic benefit, when the utilization rate of shallow geothermal energy development is 25%, about 6077 tons of standard coal can be saved in Xiongdong District throughout the year, about 2006 million yuan of annual cost can be saved, 14,501 tons of carbon dioxide can be reduced, 103 tons of sulfur dioxide can be reduced, and 49 tons of dust can be reduced.

The assessment of sustainable tourism development in the rural areas of the Aktobe oblast of Kazakhstan involved thoroughly analyzing multiple dimensions. Environmental, socio-economic, and cultural sustainability aspects were considered to comprehensively understand the region's tourism potential. The study began by evaluating the available tourism resources in rural Aktobe. This included assessing natural attractions such as landscapes, wildlife, and geological features, as well as cultural heritage sites and infrastructure like accommodation facilities and transportation networks. A crucial aspect of the study was to analyze the environmental impact of tourism activities in rural areas. This involved evaluating the effects on ecosystems and natural resources. The measures for conserving these resources were also identified. Another focus was on the socio-cultural aspects of tourism development. The study aimed to preserve local traditions, cultural heritage, and community identity amidst tourism growth. Strategies for achieving socio-cultural sustainability were devised. Ranking methods were employed to identify key factors influencing rural tourism development. These methods helped prioritize areas for improvement and resource allocation. A balanced approach was adopted to assess the interaction between different dimensions of sustainability. This ensured that environmental, economic, and socio-cultural aspects were considered equally to achieve overall sustainable tourism development. ArcGIS 10 was used for data analysis and visualization. Maps and charts were created to represent spatial and statistical information, aiding in identifying trends and patterns.

The relevance of the study is conditioned by the fact that any anthropogenic load or economic activity has an impact on the functioning of natural ecosystems, as demonstrated by the widespread practice of oil palm expansion. The purpose of this study was to develop methods for assessing strategies that play an important role in strengthening measures to protect biodiversity and ecosystems in Africa and Latin America, considering the impact of the decisions of the United Nations Climate Change Conference. The study considers the materials of various international organisations on the problems of biodiversity related to climate crises, inefficient territorial planning, expansion of land for growing crops that deplete the soil or reduce the area of land needed to accommodate biota. The paper presents a sequence of steps to assess the impact of the decisions of the United Nations Climate Change Conference on biodiversity and ecosystems. The aspects of conservation of biodiversity and ecosystems in the context of the expansion of palm plantations are substantiated. The indicators of the ratio between the available land area for palm oil cultivation and the area threatening to reduce the biodiversity of Africa are analysed. Environmental solutions are substantiated, which correspond to the provisions of the United Nations Climate Change Conference in the context of biodiversity and ecosystem conservation, taking into account the expansion of large areas for palm plantations in Colombia. The practical significance of this study lies in the development of a methodology for the economic and mathematical assessment of the decisions of the United Nations Climate Change Conference, which affect the conservation of biodiversity and ecosystems, and are the driving mechanism in creating an effective control system for tracking oil palm plantations, territorial development with the least environmental losses and high economic efficiency

This research article examines the role of the transportation network in sustainable forest management and forest use within the forest reserve. The authors discovered a link between the efficiency of multipurpose forest management and the efficiency of the forest transportation network. The authors did draw attention to the fact that there needs to be a comprehensive methodology for assessing the efficiency of network planning for forest transportation. They also found that the efficiency of forest road network planning for reserve and protective forests needs to be evaluated. In this article, the authors define the fundamental parameters of forest transportation networks based on forest type and propose a method for obtaining a reliable assessment of the forest road network's efficiency. The estimation is based on the multipurpose nature of forest use and how forest land resource potential grows based on forest category. The authors suggest a comprehensive approach based on a mathematical model which includes elements of financial mathematics, combinatorics, and mathematical statistics to assess the efficiency of forest transportation network planning. By integrating diverse methodological tools into a unified forest transportation network planning tool, it becomes possible to precisely calculate the time required to recoup the costs associated with establishing and expanding a forest road network. The model takes into account the geographical arrangement of the network's individual elements and their dependence on the specific forest category in which it is designed. They also apply a systematic approach and economic and mathematical modelling, including linear and dynamic programming. [ABSTRACT FROM AUTHOR]

Marine shale gas, represented by the shale gas from Wufeng-Longmaxi formations in southern China, is the main field for shale gas exploration and development in China. In recent years, marine shale gas exploration and development have been constantly facing new problems and challenges. Expanding new fields of shale gas resources and increasing shale gas production are still top priorities. The distribution characteristics, resource potential, and favorable area prediction of shale gas in typical marine formations in China are sorted out, with the results as follows. The geological and recoverable resources of shale gas in Wufeng-Longmaxi formations in Sichuan Basin and its peripheral regions are (17.50-33.19)×1012 m3 and (3.50-6.14)×1012 m3, respectively, with deep shale gas resources accounting for over 50%, mainly distributed in the high and steep structural belt in eastern Sichuan and in the low steep structural belt in southern Sichuan. The geological and recoverable resources of shale gas in the Permian Wujiaping Formation are (8.7-24.6)×1012 m3 and (1.3-3.7)×1012 m3, respectively, with exploration potential in areas such as Kaijiang-Liangping, Longjuba, Jiannan, and Sanxing in eastern Sichuan. The geological and recoverable resources of shale gas in the Qiongzhusi Formation are (5.69-12.71)×1012 m3 and (0.89-1.06) ×1012 m3, respectively, with favorable areas mainly distributed in areas such as Jingyan-Jianwei-Weiyuan-Ziyang in southwestern Sichuan, Nanjiang in northern Sichuan, and Yichang in the middle Yangtze region. The ancient marine formations such as the Doushantuo Formation, Hongshuizhuang Formation, and Xiamaling Formation have certain potential of shale gas resources, which are potential continuation of shale gas resources. The favorable areas for shale gas in the Doushantuo Formation are mainly distributed in western Hunan and Hubei and southeast Chongqing, while the favorable areas for shale gas in the Hongshuizhuang Formation are mainly distributed in the Chengde-Kuancheng area of Hebei. The favorable areas for shale gas in the Xiamaling Formation are mainly distributed in the areas of Zhuozhou in Hebei, Fangshan, Mentougou, Changping in Beijing, and Lanqi-yingzi. Based on this, three suggestions are further proposed for the future exploration direction of marine shale gas: the first is to focus on deep to ultra-deep and normal pressure shale gas, move towards new layers, and expand the field of shale gas exploration; the second is to deepen and enrich the exploration theory of deep to ultra-deep shale gas, normal pressure shale gas, and shale gas of new layer in the new area; the third is to focus on the improvement and innovation of deep to ultra-deep shale gas drilling and production technology and supporting equipment, and reduce the drilling and production costs of single wells of normal pressure shale gas.

The aim of the article is to substantiate the components of the resource potential of the insurer as a complex category that characterizes the activity of the subject and allows it to move towards the set goal of activity. In the analysis of professional literature in terms of the content and components of the resource potential of an economic entity, the content of the concept of «resource potential» of the insurer is clarified and its components are outlined. At that, the allocation of components was carried out taking into account the objective-subjective and resource-functional composition of the potential. As a result of the study, it is concluded that financial, material, investment, personnel, information, and technological potentials are directly related to the resources of the insurer, the relationship between which allows the company to provide quality services, apply innovations in the insurance market, provide opportunities to compete in this market and achieve the planned goals. A characterization of the mentioned types of potential is provided. In particular, the financial potential is characterized by allocating the indicators by which it should be analyzed. The material potential is described in terms of the totality of tangible assets and resources that an insurance company can or already uses in its activities. The personnel and technological potentials are characterized by directions and possibilities of their application. The informational potential is defined by a company’s ability to collect, process, store, and use information for decision-making, business process optimization, customer service, and risk management. The investment potential allows the company to receive additional funds and expand its activities. Effective use of the resource potential is manifested in the formation of strategic and market potential of an insurance company and significantly strengthens its competitive position in the insurance services market.

Continental shale oil resource is an important alternative source for increasing and stabilizing Chinaâs crude oil production. China has abundant continental shale oil resources. The opinions of researchers are divided over the classification of shale oil resources in China, resource evaluation methods and criteria, and resource potential prediction. Considering this fact, the authors of this article first summarized and analyzed the exploration progresses made in the typical shale oil exploration areas in China and the geological insights gained through exploration activities. Then, based on the current shale oil research status and actual oil production conditions in China, shale oil resources were classified into three types: interlayer shale oil, pure shale oil, and in-situ converted shale oil. Furthermore, the corresponding resource evaluation methods and quantitative models were proposed, the key parameters and their lower limits were determined and the resources of the three major types of shale oil in the shale formations in Chinaâs major basins were evaluated using a set of unified evaluation criteria. The in-place resources of pure shale oil, interlayer shale oil and in-situ converted shale oil are 145.4 Ã 108 t, 95.1 Ã 108 t and 708.2 Ã 108 t, respectively, and the recoverable resources are respectively 9.4 Ã 108 t, 7.1 Ã 108 t and 460.3 Ã 108 t. The research results can provide guidance for the evaluation of shale oil resources in China and the exploration planning for such resources and serve as valuable references for international peers to understand Chinaâs current status of research and development potential of shale oil.

The Junggar Basin is rich in oil and gas resources, with huge exploration potential, which is one of the main arenas of increasing oil and gas reserve and producing in China. In recent years, CNPC has made major breakthroughs in exploration in the Junggar Basin, revealing the orderly symbionic distribution pattern of conventional and conventional oil and gas. In order to further learn from the oil and gas achievements and exploration and development experience in neighboring areas and the new geological theories, for formulating SINOPEC's oil and gas exploration strategy in the Junggar Basin, the potential and distribution characteristics of the oil and gas resources in the Junggar Basin are systematically analyzed in this paper and it is pointed out that no enough attention is paid to natural gas and unconventional petroleum. The key breakthrough direction and exploration strategy of SINOPEC in the Junggar Basin are put forward in the paper after reviewing the major exploration breakthroughs in multiple fields, multiple strata, and multiple types in recent years and combining with the oil and gas geolo-gical conditions and exploration practice of SINOPEC's mining rights area. The research reveals that the Junggar Basin has entered a new period of exploration dominated by the middle and lower assemblage, and the exploration ideas must be adjusted accordingly. We must insist on the transformation from early outside-source exploration to intra-source and near-source exploration, and from early conventional petroleum exploration to both conventional and unconventional petroleum exploration. In order to make big exploration breakthrough of SINOPEC and realize the target of increasing reserves and production in the near and medium term in the Junggar Basin as soon as possible, four exploration strategies are proposed in the paper, including further figuring out the resources, establishing an integrated research team of conventional and unconventional petroleum, strengthening the joint research of geological and engineering integration, and increasing the support of risk exploration.

The article is aimed at solving the actual problem of studying the factors of internal and external environment of functioning of sectoral structures. The authors analyzed an aggregate of various indicators for assessing the factors of development of sectoral structures using methods of multivariate statistical analysis. The completeness of the theoretical description of objects and objectivity of conclusions during the study of the problem of factor analysis of functioning of the mechanism of management of sectoral structures has been achieved. The problem of analysis of resource and investment-innovation factors of development of sectoral structures using factor analysis is examined. It is proposed to quantify the efficiency of functioning of the mechanism of enterprise management to use indicators of assessment of resource and investment-innovation potentials, which should be considered as indicators of outputs of the production system, transformed and obtained as a result of the influence of the management mechanism. The analysis was carried out in two directions: resource and investment-innovation. A large number of indicators characterizing the state of the internal and external environment of enterprises were processed, and using the methods of factor analysis, they were replaced with a certain set of uncorrelated parameters, which allowed to reduce the dimension of the studied totality of data. The state of resource and investment-innovation potentials of enterprises was considered as a result of the influence of the management mechanism, taking into account industry affiliation, that is, separately for enterprises of mechanical engineering, light or food industries. As result of the analysis, the following general factors were formed for light industry enterprises: economic direction of capital use; efficiency of use of the labor and material resources; efficiency of use of the equity and borrowed capital; efficiency of use of the borrowed funds. For food industry enterprises, the following factors are formed: the economic direction of capital use; efficiency of the financial and production activities; the ability of the management mechanism to provide a stable amount of profit; efficiency of use of fixed assets. Within the terms of investment and innovation direction for mechanical engineering and light industry enterprises, the most important factor is that which can be interpreted as the efficiency of research activities, the less important factor – the direction of using own investments for innovation; of the smallest importance is the direction of using investment resources for the production of innovative products.

The purpose of the study is to improve the methodological support for the assessment of the financial efficiency of the agricultural sector of Ukraine under the influence of the innovative potential management of its resource provision. The main scientific methods used in the study are fundamental provisions of the theory of innovation and finance, correlation and multifactor regression analysis, mathematical programming, etc. According to the results of the conducted research the parameter of technological progress as an indicator of the level of innovation development of the agrarian sector of the Ukrainian economy was obtained after modelling of autoregressive multiplicative Tinbergen-Solow production function. The numerical value of the technological progress parameter indicates a potential for additional growth in agricultural output of +0.142%, while other conditions remain unchanged. 23 indicators of the state of the resource provision of the agricultural sector were systematized in 4 groups: the results of the production activity of the agricultural sector (6 indicators), the resource supply of the agricultural sector (8 indicators), the efficiency of the use of resources by agricultural enterprises (4 indicators), and sustainability of the financial condition of agricultural enterprises (5 indicators). A power-law four-factor regression model of the impact of the output volume of the agricultural sector, the value of current assets, return on capital and the current liquidity ratio on the volume of net profit of agricultural enterprises of Ukraine was obtained. It is proved that the elasticity of net profit for agricultural output is 0.01%, for the value of current assets - 1.46%, for capital accumulation - 0.72%, for current liquidity - 3.2%. We constructed the target functions of maximization of the agricultural production output on the basis of the Tinbergen-Solow production function, net profit on the basis of the four-factor power model of net profit, return on equity on the basis of the two-factor DuPont model for the short term. The solving of target functions allowed for maximization of the return on equity of agrarian enterprises of Ukraine only at the expense of the existing innovation potential of production resources and will be used in further research by the authors.
