 The trend towards the development of rural tourism is recognized to create positive dynamics for the revitalization of rural areas, and the preservation of the authentic and socio-cultural image of rural areas. Rural tourism in the regions of Kazakhstan is at the initial stage of the development. Aktobe oblast is not an exception to the general Kazakhstani trend. In the Aktobe oblast, to date, regional programs for realizing the potential of rural areas in the field of rural tourism have not been developed. An analysis of the state of the cultural environment and natural features made it possible to identify profitable resources in the local socio-economic system of the Aktobe oblast, on which rural tourism of the studied area can be built. The main directions of the resource application for the development of rural tourism are formed based on the potential resources that are available not only to the region as a whole but to each administrative-territorial unit – the district. As part of the study of the territorial system of the Aktobe oblast, regional guidelines for the development of rural tourism were identified. Rural tourism in the Aktobe oblast can be built on the resources of both natural and agricultural, historical, and cultural environments. Cultural landmarks for the development of rural tourism are represented by historical and cultural objects. We see the approach to assessing the territory of the Aktobe oblast in terms of organizing directions for the development of rural tourism in the application of the inductive method of scientific knowledge when the overall picture is formed based on the transition from a particular study of objects and phenomena to a general one. In our case, a holistic view of the development of rural tourism is obtained by analyzing natural resources, transportation, historical and cultural values of the territory and agricultural production. Insufficient and irrational use of the tourist opportunities of the territory, as well as the growing needs of the population for outdoor recreation within their region, stimulate the search. For new approaches to planning tourism activities. A new policy of rural tourism seems promising, aimed not only at the implementation of specific tourism projects but at the systemic development of tourism in the Aktobe oblast. The article develops a methodology for assessing the resource potential for the development of rural tourism and proposes the principles of zoning the territory from the standpoint of the territorial organization of rural tourism. To achieve this goal, the paper used the method of scoring, cartographic and comparative methods. Their application made it possible to ensure the validity and reliability of conclusions and proposals.

 Beedanahalli Watershed, hydrogeochemical experiments were conducted to evalu- ate the quality and suitability of groundwater for drinking. Thirty-one groundwater samples were taken in 2022’s pre and post-monsoon seasons. Groundwater’s physiochemical characteristics, including pH, EC, TDS, Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42-, and NO3-, were measured. The overall hydrochemistry of the groundwater samples in both seasons is shown in Gibb’s (1970) diagrams as occurring in the rock dominance field. Assessment of groundwater quality is important in the current situation. The primary goals of the current study are to evaluate and classify the groundwater quality for drinking. To evaluate the subsurface water in the study area, 14 distinct physiochemical parameters were examined. The Bureau of Indian Standards (BIS) was attracted to make a comparative analysis of the values. The water quality index is one of the finest ways to determine whether groundwater is safe to drink (WQI). The extracted components show that topography, agronomic, rainfall, domestic sewerage, and production drain water were among the factors that caused the sources to exceed the allowable limit. The recent study indicated that some groundwater samples had extremely poor water quality, showing that the region is mostly affected by rock weathering and salt evaporating from the bedrock into the water supplies, posing a major threat to the natural ecosystem.58% and 51% of groundwater samples taken before and after the monsoon, respectively, were determined by the WQI index to be appropriate for drinking.

 The article points out the necessity of researching the problems of assessment tourist resources in the conditions of war. Possessing a significant potential of tourist resources, Ukraine now needs to develop a comprehensive strategy for the preservation, restoration and modernization of tourist resources. Tourism is one of the priority areas of economic and cultural development of many countries and an important component of the socio-economic development of each of them. It is worth noting that with the beginning of the full-scale Russian invasion, the tourism sector suffered a lot. However, it is already clear today that the losses in tourism will be significant and some tourist resources will be impossible to restore, while others will probably be rebuilt only after the end of the war. The purpose of this paper is to assess the losses of tourist resources in the conditions of armed confrontations and propose new solutions for the use of tourist resources in the period of post-war reconstruction. The research methodology uses methods of complex analysis and synthesis, deduction and induction, as well as content analysis of the main statistical and scientific sources for expert evaluation of the indicators of tourist resources. The proposed methodology is based on the construction of an integral index assessment. To evaluate the quality characteristics of tourist resources, we chose such indicators as the availability of these resources, attractiveness, readiness for implementation, availability of infrastructure for implementation, advertising and infor- mation support, price policy regarding their implementation, and staffing of the analysed tourist resources of the region. As a result Transcarpathia (0.87), Odesa (0.82), Ivano-Frankivsk (0.82), Lviv (0.87), Ternopil (0.73), Chernivtsi (0.73) regions have high values of the integrated assessment of tourist resources. The next group of regions – Kyiv (0.65), Dnipropetrovsk (0.53), Zaporizhzhya (0.53), Volyn (0.51), Kirovohrad (0.51), Poltava (0.6), Rivne (0.6), Vinnytsia (0.53), Khmelnytskyi (0.62), Kharkiv (0.58), Cherkasy (0.56) regions – fell into the middle group according to the integrated assessment of tourist resources. The lower group includes Zhytomyr (0.45), Mykolayiv (0.47), Kherson (0.42), Sumy (0.42), Donetsk (0.16), Luhansk (0.20) regions. The paper analyses the current state and substantiates the demand to create an individualized tourist product that would meet the constantly changing nature of tourists’ needs and could be flexibly and quickly transformed under the influence of political, economic and other factors of world development. As a result, there is a deepening, expansion and diversification of types of tourist resources, which satisfies the increasingly complex demands of modern people in the variety of recreation and leisure, development of new directions and markets of international tourism.

 The present paper aims to evaluate the accuracy of classifying Land Use /Land Cover (LULC) types and assesses the trends of their changes in the Eastern Part of Batna City (Northernf Algeria) using remote sensing and GIS. The accuracy of image Land Satellite (Land Sat ) was evaluated using the supervised classification technique, it’s applied in multi spectral and multi temporal satellite data acquired in 2000,2010,2022 and assessed with GOOGLE EARTH PRO and IMAGERY Land Use and topographical map. The second part focused on extraction of LST in three phases and explored the relationship between two land cover indices (NDVI, NDBI) and LST.LU/LC detected, quantified, and stati- cally analyzed, the result indicate that from 2000-2022 the built-up areas increased by 0.34% (6.638km2), the forest area increased by 1.8% (35.144km2), agricultural land cover increased by 1.12% (21.867km2), while bare land decreased by 2.17% (42.368km2). The conversions of areas from bare land to urban land represent the most significant Land Cover changes. The accuracy assessment and correlation coefficient R2 analysis in this study affirms the previous research findings. Even a single land use unit like built-up area, bare land and vegetation also create differences in LST (R2 of NDBI vs. LST ranges from 0.64 to 0.79; NDVI vs. LST ranges from -0.73 to -0.82). With the change of the LU/LC style, its imprint is reflected on the LST. Therefore, immediate reflection on new urbanism must be adopted, initiated and implemented to stop the warming that contributes to climate change in the study area.

 Public diplomacy, as a special form of foreign policy activity aimed at shaping foreign public opinion as a factor in changing the policy of another state, requires the study of the peculiarities of geopolitical and geocultural perceptions of the foreign public. Public diplomacy has become an important channel of international communication between Ukraine and the civilized world since the beginning of the full-scale Russian offensive on its territory. The role of President of Ukraine Volodymyr Zel- enskyy in transforming public diplomacy into an effective technology of international politics is unprecedented. The uniqueness of V. Zelenskyy’s contribution to the development of public diplomacy as an international communication practice lies, first, in the incredible rise in the importance of the head of state as the main actor of such diplomacy, second, in its institutionalization and intensification as a tool for influencing global public opinion, third, in its tangible effectiveness and efficiency, and fourth, in the widespread use of digital online technologies for its implementation. The success of V.Zelenskyy’s public diplomacy is not just due to its geographically relevant content, but also to communication technologies based on geographic determinism. His public diplomacy is based on universal values, but adapted to the geocultural characteristics of the foreign public. The Ukrainian president sought to make the Ukrainian position understandable to geoculturally different audiences through a number of persuasive technologies. First of all, he used the technology of joining by appealing to values common to all geographical regions, such as life, security, freedom, children, and family. In addition, the Ukrainian national leader used the technology of engaged communication, which is empathetic, compassionate in nature and based on respect for the values, symbols, ideals, tragedies and losses that make up the geocultural background of the public’s worldview in each country. In conducting public diplomacy, the Ukrainian president outlined the geography of danger from the potential Russian threat,including the countries that were part of the USSR and the Soviet bloc. The Ukrainian national leader’s use of the technique of linking the geography of the Russian threat to the Soviet past is justified in the light of official and semi-official Russian propaganda. Exposing Russian disinformation has become one of the leading directions of V.Zelenskyy’s public diplomacy and the main information weapon against the aggressor. In proving the falsity of Russian propaganda, the Ukrainian national leader appeals to the facts, to the reasons for the distortion of the objective picture of reality and to the special geocultural experience of the foreign public, which is determined by significant historical events in a particular geographical area of the world.

 The article considers the geodynamic regime of the South Caspian depression, de- fines the directions of compressive stresses, the role of the latter in changing the thickness of sedimentary formation complexes, in the formation of local uplifts and their complication by faults and mud volcanism. The purpose of the study is to research the geodynamic regime and determine the oil and gas content of the South Caspian depression. The article reflects the features of studying the zone of pseudosub- duction in the South Caspian depression and the analysis of the obtained results of the prospects of oil and gas potential from the point of view of the influence of modern geodynamic processes. The study of the intensity of the formation of sedimentary facies complexes in the South Caspian depression and the features of the intensity of sedimentation allows us to distinguish 4 stages in different time intervals. According to the analysis of the available data, an inverse relationship has been established between the duration of each stage and the thickness of deposits accumulated during this period of time. In other words, the shorter the duration of the stage, the greater the thickness of the formed deposits. It was found out that this is the result of geodynamic processes occurring within the Southern Caspian Sea and in the adjacent areas, and due to the prevailing geodynamic conditions, the uncompensated deflection regime prevailing for the bottom of the South Caspian Basin had a direct impact on the process of oil and gas formation in its sedimentary cover. The depths of the boundary isotherms of catagenesis and the zone of oil and gas formation were determined in order to determine the state of each sedimentary-facies complex in the vertical zonality of oil and gas formation. It was found that in the western part of the South Caspian Basin, the lower boundary of the protocatagenesis zone is 3 km, the isotherm of the lower boundary of the oil window corresponding to 1500 C is located at a depth of 11-12 km, and the depth of the main gas formation zone corresponding to 2500 C is 18-19 km. The presented analysis of the features of oil and gas formation makes it possible to predict the formation of liquid hydrocarbon deposits at depths corresponding to the oil formation zone.

 The chemical composition of groundwaters of fractured Precambrian crystalline rocks corresponding to the Ukrainian Shield aquifer system was investigated. Using the ex- ample of surveyed aquifers of the Vinnytsia and Zhytomyr regions, the similarity of the quantitative and qualitative composition of groundwater confined to the same hydrogeological structure is proven, which is due to similar natural conditions of resource formation (geological structure, the chemical composition of water-bearing rocks, rates of water exchange, amount of atmospheric precipitation, etc.). The dominant role of sulfates in the anionic composition of water samples from the aquifer in the fractured zone of crystalline rocks and their weathering crust (Vysokyi Kamin village, Zhytomyr region) was established. For the Zhytomyr region groundwaters, the dynamics of changes over time in such indica- tors of the general chemical composition as total mineralization, Ca, Mg, SO4, and Cl ions were analyzed for 2017-2019. A significant correlation was found between the concentrations of Mg, SO4, and Cl and their normalized indicators by the amount of water intake, which indicates that the content of mineral substances increases in the studied aquifer with an increase in water withdrawal. This is the evidence of the essential role of the anthropogenic factor in the formation of the general chemical composition of these waters. Using the method of mass spectrometry with inductively coupled plasma (ICP-MS), the features of the trace element composition of groundwaters of the Ukrainian Shield fractured crystalline rocks were established. The obtained concentrations of elements were com- pared with normative values of the World Health Organization and biologically significant concentrations. The lack of several essential elements was revealed. The key potential risks for the health of the population, which constantly uses the investigated groundwaters for economic and potable needs, was outlined. Moreover, the high probability of occurrence of microelementoses with regular use of the investigated groundwaters is emphasized, which are associated with a significant deficiency of such vital elements as Cr (in the Vinnytsia region), Mn, Cu, and, especially, Zn, the content of which is critically low. Subsequently, the findings of this study can serve as a basis for carrying out biogeochemical zoning with the selection of relevant taxa (provinces).

 Biodiversity loss is irreversible and demands investment in organizational measures for environmental protection and effective risk management of relevant financial investments to ensure national economic security. This research analyzes the directions of investment support for economic security based on rational interaction between society and ecosystems. The goal of this article is to identify the main directions of anthropogenic impact on the environment and the interdependence of improving ecological indicators through investment activities in the corresponding direction to ensure economic security. The study examines investment directions in environmental protection within the LIFE program projects to prevent negative cause-and-effect effects from the implementation of natural innovations. The maximization of the EU’s efforts in ecosystem restoration and protection is identified to mitigate investment risks by promoting the adoption of innovations across a wider range of societal spheres. It is estimated that during the period from 2018 to 2022, there was an increase in investment in environmental protection by approximately 18%, resulting in areduction in emissions intensity by 22.9% by economic activity types from 2016 to 2021, and the average CO2 emissions indicator contributed to a decrease by 1.1%. Investing in the environment requires continuous adaptation to changing external conditions and requires adjustments to reduce risk threats, such as unforeseen consequences of financial investments in certain economic sectors, shifts in societal behavior, and unexpected ecosystem impacts. However, effective management of investment risks is a potential for the development of environmental investment activities, such as the implementation and support of sustainable innovations (transition to eco-friendly construction, reforestation, raw material certification).

 The paper draws attention to the ecological-economic aspects of mining thin coal seams in the strategic coal-mining region of the Western Donbas and studies their causes and consequences in detail. It has been analyzed and determined that as a result of coal mining with complete caving of rocks, the processes of the earth’s surface subsidence above the mine fields occur. Due to the proximity of groundwater to the surface, waterlogging of territories and a change in the landscape occur. Using analytical calculations, it has been determined that the total surface subsidence value above the mine field of one of the Western Donbas mines is 1.2 m, which, according to the monitoring of environmental authorities, correlates well with the range of subsidence values in the region of 0.7-1.4 m. The places and parameters of rock dumps accumulating on the earth’s surface in coal mines are identified and analyzed, and the sources of waste rock formations in the technological system of coal mines are also studied. It has been revealed that the largest ingress of all waste rocks to the surface is caused by the stope operations conducted with undercutting of bottom rocks – 39% and underground mining operations to prepare new coal reserves for extraction – 33%. To date, it has been found that the volumes of waste rocks generated in mines are 1.5 times higher than the volumes of their utilization, and the prospect of disturbed land reclamation is limited in time, which, with today’s mining technology, will lead to an increase in their accumulation again. Based on a comprehen- sive study of the mined coal seam structure with a complex texture, using the example of one of the mines, it has been revealed that in the formation of operational ash content, the friable roof caving amounts to 13.0%, the seam rock interlayers – 19.2%, the coal seam natural ash content – 12.8%, and the seam bottom rock undercutting – 55.0%. A close linear relationship has been determined between the value of bottom rock undercutting with a shearer based on collected mine data and the indicator of mined coal operational ash content, which confirms the greatest importance of this factor. It has been proved that the most important factor influencing the formation of the mined coal operational ash content is the undercutting of the seam bottom rocks by a shearer, and with a 2-fold decrease in the ash content of coal, its energy potential increases by 1.25 times. Possible scenarios for the coal mining development in the Western Donbas are considered and a rational direction for solving the leading ecological-economic problems of underground mining of thin coal seams is proposed.
