Item Assessing Climate Aridity Trends in Southern Ukraine during 1991-2020(2023) Boychenko, Svitlana; Kuchma, Tetyana; Maidanovych, Nadiia; Myronova, T.Assessment of Climate Aridity Trends in the Southern Region of Ukraine was conducted using data meteostations for the period 1991-2020. The analysis of climate aridization trends over the past 30 years in the study region has revealed a notable intensification of this process, especially in recent years. The hottest summer months occurred in 1992, 1999, 2001-2003, 2007, 2010, 2012, and 2017-2019. These periods were marked by anomaly high temperatures, dry winds, extended non-rainfall periods, and low air humidity, often reaching as low as 30%. Over the past 30 years, from March to October, the Southern Region experienced an average of 203±6 non-rainfall days, with a trend indicating an increase by an average of 0.4±0.1 days per 10 years. Conversely, the number of days with relative humidity up to 30% on the March–October time scale averaged 41±16 days, with a tendency to increase by 1.2±0.7 days per 10 years. The highest occurrence of days with relative humidity up to 30%, on average in the region, is typically observed in July and August (7 and 10 days per month, respectively). To assess climate aridity and calculate drought severity for vegetation were used a satellite-derived Vegetation Health Index (VHI). Drought indices derived from the summed VHI values in August for the years 2007, 2018, and 2020 in the Southern Region of Ukraine are presented.Item Логістична інфраструктура в умовах війни та повоєнного відновлення України(Видавничий дім "Києво-Могилянська академія", 2024) Горошкова, Лідія; Меньшов, ОлександрМатеріали доповіді учасників ІІ Міжнародної науково-практичної конференції "Менеджмент та маркетинг як фактори розвитку бізнесу", 17-19 квітня 2024 р.Item A century-long tendency of change in surface air temperature on the territory of Ukraine(2024) Boychenko, Svitlana; Maidanovych, NadiiaEarly historical meteorological observations of air surface temperature on 11 meteostations in Ukraine (since 1808) were analyzed. However, since a larger number of stations have time series of temperature starting in 1821—1825, for more reliable estimates of the linear trend, the period 1824—2021 was required. The trend is 0.78 °C per 100 years for this period. According to the analysis of meteorological data, the average annual surface air temperature on the territory of Ukraine in 1900—2021 was 8.6±0.9 °C. However, for the more recent period of 1991—2020, it increased to 9.5±0.9 °C. The temperature in Ukraine exhibited an increase of 1.31±0.42 °С per 100 years during 1900—2021. Over the last 30 years, a more pronounced increase in annual surface air temperature, by 0.79±0.08 °C per decade, was observed. Changes in the temperature regime exhibit spatio-temporal patterns. In most parts of Ukraine in 1900—2021, a temperature increase is within 1.5—2.0 °C per 100 years. Simultaneously, some parts of northern, northwestern, and eastern regions, as well as the Vinnytska and Zaporizhzhska oblasts, are characterized by more intense warming, reaching 2.0—2.5 °C per 100 years, in contrast to southwestern, southern regions, and the territories adjacent to the Ukrainian Carpathians, where the temperature rise is within 1.0—1.5 °C per 100 years. Temperature anomalies from 1900 to 2021 indicate the lowest annual averages occurred in 1933, 1956, 1976, 1985, and 1987, while the highest annual averages were observed in 2007, 2015, 2019, and 2020. Between 1900 and 2021, the average monthly air temperature in Ukraine substantially increased in colder months (from October to March), ranging from 0.7 to 2.0 °C per century. Simultaneously, warmer months (from April to September) saw an elevation ranging from 1.0 to 1.9 °C per century. In the 1991—2020 norm, an overall warming trend of 0.5—1.3 °C per decade was observed. Notably, January showed a slight decrease in the warming rate, with a trend value of –0.1 °C per decade. An indicator of the seasonality of climatic conditions is the amplitude of surface air temperature (A). In Ukraine, the average amplitude A was 12.7±1.1 °C from 1900 to 2021 and 12.5±0.8 °C from 1991 to 2020. Analysis of the temperature amplitude over the 20th century and the early 21st century revealed a general tendency of decreasing A values (the trend is –0.5 °C per 100 years), primarily due to warming in the colder months. However, from 1991 to 2020, the trend in A values was only –0.001 per decade, attributed to a significant temperature rise during the warmer months. Based on the analyses of the Johansson-Ringleb continentality indices in Ukraine, the indices’ values were determined to be 59.3±3.7 for the period spanning from 1900 to 2021, and 59.0±3.4 from 1991 to 2020. An overarching trend indicates a decrease by 0.4 % per 100 years. However, from 1991 to 2020, a contrasting pattern emerged, revealing an increase by 6.4 % per decade. The three scenarios of annual average surface temperature changes in Ukraine (SSP1- 2.6, SSP2-4.5, and SSP3-7.0) relative to pre-industrial levels in the late 19th century, based on greenhouse emissions scenarios by 2100, are discussed.Item From acidophilic to ornithogenic: microbial community dynamics in moss banks altered by gentoo penguins(2024) Prekrasna-Kviatkovska, Yevheniia; Parnikoza, Ivan; Yerkhova, Anna; Stelmakh, Olesia; Pavlovska, Mariia; Dzyndra, Marta; Yarovyi, Oleksandr; Dykyi, EvgenIntroduction: The study explores the indirect impact of climate change driven by gentoo’s penguin colonization pressure on the microbial communities of moss banks formed by Tall moss turf subformation in central maritime Antarctica. Methods: Microbial communities and chemical composition of the differently affected moss banks (Unaffected, Impacted and Desolated) located on Galindez Island and Сape Tuxen on the mainland of Kyiv Peninsula were analyzed. Results: The native microbiota of the moss banks’ peat was analyzed for the first time, revealing a predominant presence of Acidobacteria (32.2 ± 14.4%), followed by Actinobacteria (15.1 ± 4.0%) and Alphaproteobacteria (9.7 ± 4.1%). Penguin colonization and subsequent desolation of moss banks resulted in an increase in peat pH (from 4.7 ± 0.05 to 7.2 ± 0.6) and elevated concentrations of soluble nitrogen (from 1.8 ± 0.4 to 46.9 ± 2.1 DIN, mg/kg) and soluble phosphorus compounds (from 3.6 ± 2.6 to 20.0 ± 1.8 DIP, mg/kg). The contrasting composition of peat and penguin feces led to the elimination of the initial peat microbiota, with an increase in Betaproteobacteria (from 1.3 ± 0.8% to 30.5 ± 23%) and Bacteroidota (from 5.5 ± 3.7% to 19.0 ± 3.7%) proportional to the intensity of penguins’ impact, accompanied by a decrease in community diversity. Microbial taxa associated with birds’ guts, such as Gottschalkia and Tissierella, emerged in Impacted and Desolated moss banks, along with bacteria likely benefiting from eutrophication. The changes in the functional capacity of the penguin-affected peat microbial communities were also detected. The nitrogen-cycling genes that regulate the conversion of urea into ammonia, nitrite oxide, and nitrate oxide (ureC, amoA, nirS, nosZ, nxrB) had elevated copy numbers in the affected peat. Desolated peat samples exhibit the highest nitrogen-cycle gene numbers, significantly differing from Unaffected peat (p < 0.05). Discussion: The expansion of gentoo penguins induced by climate change led to the replacement of acidophilic microbiomes associated with moss banks, shaping a new microbial community influenced by penguin guano’s chemical and microbial composition.Item Algorithm for simulating melting polar ice, Earth internal movement and volcano eruption with 3-dimensional inertia tensor(2023) Matsuki, Yoshio; Bidyuk, PetroThis paper reports the result of an investigation of a hypothesis that the melting polar ice of Earth flowing down to the equatorial region causes volcano eruptions. We assumed a cube inside the spherical body of Earth, formulated a 3-dimensional inertia tensor of the cube, and then simulated the redistribution of the mass that is to be caused by the movement of melted ice on the Earth’s surface. Such mass distribution changes the inertia tensor of the cube. Then, the cube’s rotation inside Earth was simulated by multiplying the Euler angle matrix by the inertia tensor. Then, changes in the energy intensity and the angular momentum of the cube were calculated as coefficients of Hamiltonian equations of motion, which are made of the inertia tensor and sine and cosine curves of the rotation angles. The calculations show that the melted ice increases Earth’s internal energy intensity and angular momentum, possibly increasing volcano eruptions.Item Перспективи співробітництва між геологічними музеями України та Іспанії(2023) Деревська, Катерина; Нестеровський, В.; Руденко, К.; Лівенцева, Г.Публікація актуалізує питання стосовно перспективи розвитку геологічної науки та шляхів співробітництва між Україною та Іспанією. У рамках двостороннього співробітництва між даними країнами у кінці лютого 2023 р. відбулася зустріч геологів у Барселоні в одному з провідних науково-дослідних інститутів в Іспанії. Головними питаннями, які обговорювалися, були популяризація геології та розвиток геологічних музеїв. Стаття у першій частині містить огляд особливостей тектонічної будови, стратиграфії, породних комплексів, унікальних еталонних розрізів у межах України, що мають світове наукове значення. Друга частина присвячена характеристиці українських музеїв наук про Землю, проблемам сучасних наукових досліджень, збереженню геологічних пам’яток, посиленню ролі геологічних музеїв у популяризації знань про Землю. У підсумку запропоновані спільні проєкти в рамках міжнародної співпраці між Україною та Іспанією. Співробітництво відбуватиметься на рівні окремих інститутів наук про Землю і природничих музеїв, оскільки вони зберігають первинну геологічну інформацію. Для акумуляції геологічної інформації, її збереження і презентації необхідно об’єднати музеї в єдиний музейний простір, а також у міжнародні музейні організації. Створити загальну комплексну багаторівневу музейну базу даних. Крім того, співробітництво може проявлятися у спільних експедиціях, в яких можна отримати фактичний матеріал для подальших аналітичних досліджень; в організації та проведенні спільних досліджень, конференцій, навчальних семінарів; публікації спільних наукових праць тощо. Такі заходи сприятимуть обміну інформацією/зразками та покращенню зовнішньої комунікації для подальшого розвитку музейної справи, освітньої та наукової діяльності у геологічній галузі.Item Bioactive substances of Colobanthus quitensis (Kunth) Bartl. from the Darboux and Lagotellerie Islands, western coast of Antarctic Peninsula(2023) Ivannikov, R.; Anishchenko, V.; Poronnik, O.; Myryuta, G.; Miryuta, N.; Boyko, O.; Hrytsak, L.; Parnikoza, IvanThe study aimed to investigate a wide spectrum of biologically active substances of an aboriginal Antarctic plant (Colobanthus quitensis) from the central and southern parts of its Antarctic part of general spread collected in 2020–2022. For 17 plants from 2 populations, we obtained extracts and analyzed them using high-throughput chromatography (HPLC). This was the first biochemical screening of plants from previously not investigated parts of this species’ range (Graham Coast and Marguerite Bay in the maritime Antarctic). The HPLC method characterized the overall metabolite pools and their separate components which could potentially have high biological activity. The most numerous groups of compounds included phenols and benzoic acids, hydroxybenzoic acids, hydroxycinnamic acids, flavonoids, apigenin glycosides, luteolin glycosides, tricin glycosides, flavonoid conjugates of the hydroxycinnamic acids, chlorophyll catabolites, carotenoids, terpenoids, and sterols. The quantitative content of the pearlwort’s metabolites depended on the population, probably due to the differences in the microhabitats. Meanwhile, such variability offers a wide selection of possible targets for biochemical screening. The Antarctic pearlwort is richer in some conjugates (such as flavonoid conjugates with the hydroxybenzoic acids) than the other Antarctic aboriginal plant – Antarctic hairgrass (Deschampsia antarctica). The determined substances might potentially be of great practical significance.Item Recent advances in functional materials for rare earth recovery: A review(2023) Artiushenko, Olena; Freire da Silva, Raphael; Zaitsev, VolodymyrRare Earth elements (REEs) were considered as one of the 14 critical mineral raw materials that are a crucial part of high-tech and everyday consumer products. The demand for REEs has rapidly grown in recent years since they are used in high-tech and sustainable technologies such as high-performance magnets, rechargeable batteries, and low-energy fluorescent lamps. Due to the latest political tensions and low substitutability of REEs mining technology, the REEs world market is at risk. One of the crucial concepts of industrial strategy to reduce supply risks related to critical raw materials is to increase their recycling. Among others, end-of-life electronic equipment such as mobile phones, fluorescent lamps, and computer hard drives (e-waste) can be a promising source for REE recovery. Critical parameters for adsorptive recovery of REEs from e-wastes are selectivity that can be provided by functionalization of the adsorbent surface. The scope of this review is an insight into current achievements in the adsorptive recovery of REEs from solutions with a high content of transition and heavy metals. The review covers resent advances in the synthesis and application of metal chelating, ion imprinted and porous polymers; silica-based adsorbents with covalently and non-covalently attached ligands; magnetic and green adsorbents; metal-organic frameworks and carbon-based nanomaterials for REEs recuperation. Special attention was paid to emerging materials, such as green and hybrid adsorbents containing carbon nanoparticles. The adsorbents’ efficiency, selectivity, and peculiarities of their application are revealed by critical analysis of the essential conditions of the rare earth elements recovery experiment. Different experimental parameters revealing adsorbents efficiency and selectivity, such as optimal pH working range, adsorption capacity, kinetic data, design of the REEs adsorption experiment, the effect of coexisting ions, and recovery degree, are presented in the review. Advances and drawbacks of each class of the adsorbent presented were highlighted in the review, as well as modern tendencies in developing adsorbents.Item Туристична привабливість промислових територій (на прикладі Криворізької агломерації)(Каменяр, 2020) Деревська, Катерина; Спиця, Роман; Мирижук, Єлизавета; Сільченко, Геннадій; Кочубей, Єлизавета; Шевчук, ОленаОдним з найперспективніших об’єктів для розвитку геологічного, екологічного та промислового туризму є Криворізька агломерація. Цьому сприяє унікальна геологічна, тектонічна і геоморфологічна будова, наявність об’єктів природно-заповідного фонду України та майже 250 річна історія антропогенного освоєння.Item Прогнозування видобування та використання нерудних корисних копалин для будівництва в умовах повоєнного відновлення України(2023) Горошкова, Лідія; Меньшов, ОлександрПроведено моделювання з метою формування системи управління раціональним видобуванням та використанням мінерально-сировинних ресурсів України на прикладі нерудних корисних копалин для будівництва і забезпечення умов повоєнного відновлення країни. Запропоновано прогнозні обсяги щодо видобутку та раціонального використання формувати з урахуванням потреб технологічно споріднених галузей. Проведено аналіз офіційних статистичних даних щодо обсягів видобутку каміння будівельного, піску будівельного та сировини керамзитової впродовж дослідженого періоду (15 р.) і встановлено, що коливання показників як за обсягами видобутку, так і за темпами їх зростання мають періодичний, циклічний характер, вони корелюються між собою та пов'язані із загальноекономічним станом будівельної галузі та країни. Доведено, що вирішити проблему раціонального використання корисних копалин можливо шляхом більш збалансованого їх видобутку, а саме встановлення кореляції між видобутком та обсягами використання. Для прогнозування розвитку галузі використано авторську економіко-математичну модель прогнозування розвитку складних систем. Доведено, що така модель дозволить управляти обсягами видобутку технологічно споріднених корисних копалин у взаємозалежності від обсягів їх використання. Доведено, що в умовах війни внаслідок руйнування інфраструктури країни існує необхідність внесення коректив у модель для збалансованого видобутку та використання нерудних корисних копалин для будівництва з урахуванням утворених будівельних відходів та потреб повоєнного відновлення країни та її інфраструктури. Проведено моделювання з урахуванням нових умов розвитку галузі й країні, сформовано прогноз на п'ятирічний період щодо видобутку та використання піску будівельного, каміння будівельного та сировини керамзитової.Item Monitoring and modelling of environmental pollution in the Southern regions of Ukraine(2022) Khlobystov, Yevhen; Horoshkova, Lidiia; Varianichko, Valeriia; Skrynchenko, K.; Horoshkov, Stanislav; Tsurika, L.To model the situation with the emissions of air pollutants taking into account the identified trends of the emissions of air pollutants and the main impact factors, the approximation, smoothing dynamics and trend line of Microsoft Excel were applied to determine regression equations and check significance and accuracy of the built models. Statistical modelling of air pollution safety limits was applied as well. To determine the factors affecting emissions of air pollutants, the index of cross-correlation was used. It has been proven that the regional ecological condition impacted by the emissions of air pollutants depends on the priority types of economic activity.Item Climate impact drivers provoke fires in protected areas of Polissia(2022) Karamushka, Victor; Boychenko, Svitlana; Nazarova, OlhaThe purpose of the research was to analyze the dynamic of the climate impact drivers (CIDs) in the Regional Landscape Park Mizhrichynskyi (RLPM), Chernihiv Region, and to determine changes occurred in the protected areas affected by CIDs using the satellite monitoring data. It is shown that in the region for the period 1991-2021, such CIDs as the average annual surface temperature have a tendency to increase (the rate is 0.68оС per 10 years, average annual value is 8.4±0.9оС), while atmospheric precipitation tends to decrease by 5-7% per 10 years (-24 mm per 10 years, an average annual value is 581±94 mm). During periods with minimal precipitation and high temperatures, conditions favorable for the development of fires arise. Such conditions were observed in 2020. As a result of the fire in the RLPM (April 2020), more than 650 hectares of forest ecosystems were affected. Using the satellite monitoring data, the area of the territory covered by the fire was determined, and using the Normalized Difference Vegetation Index as an indicator, the development of successional processes in this territory was recorded. Field studies confirm the occurrence of pioneer species in the fires. The list of these species includes but not restricted to Viola tricolor, Pinus sylvestris, Salix rosmarinifolia, Corynephorus canescens, Oenothera biennis L., Hieracium pilosella L.Item Risk management and lost profits calculations of business entities(2022) Horoshkova, Lidiia; Antoniuk, D.; Vasyl'yeva, O.; Markova,S.; Filipishyna, L.The methodology of lost profits assessment for a business entity as a result of military actions (aggression) has been developed. The methodology includes calculation of business entity`s main operational indicators (groups of indicators) based on the analysis of its financial, accounting and tax reporting. It also takes into account the peculiarities and types of business activity when calculating the lost profits. When calculating the lost profits, it is advisable to take into account the specifics of doing business in various sectors of national economy. Qualified personnel loss and additional training costs play an important role in manufacturing; service sector could make no gain without damage or property loss; agricultural sector is the most vulnerable sector in terms of lost profits caused by the war, as well as the most complicated field to calculate the lost profits due to the large number of impact factors to be taken into consideration.Item Regularities of changes in the recreation ecosystems’ quality parameters in space(2022) Arkhypova, Liudmyla; Korchemluk, M.; Horoshkova, Lidiia; Khlobystov, Yevhen; Stakhmych, YuliiaOur study of the Danube hydro-ecosystems of the Carpathian region using of the integrated natural water quality assessment resulted in obtaining the functional dependencies between quality indicator and altitude. For the first time, the regularities of changes in the ecosystems’ quality parameters in space were established by means of developing functional dependences among the ecological standard values of the composite quality indicators of natural waters and the river length and terrain altitude, and performing the statistical processing of the database containing the results of the quality monitoring observations of the upper reaches of the Danube ecosystems in the Ukrainian Carpathians for the period from begin 21 st. The obtained dependencie and map can be used for the Carpathian region as the territorial background standard values of the ecological state indicators of basin ecosystems, which will help to scientifically substantiate the ecologically safe values of the anthropogenic pressure.Item Assessing the influence of height above sea level and geographic coordinates on surface air temperature values for a plain part of Ukraine(2022) Boychenko, Svitlana; Maidanovych, N.; Zabarna, O.The main principles of the methodology for assessing the influence of height above sea level and geographic coordinates (latitude and longitude) on the values of annual and average monthly temperature in Ukraine for the period 1991-2020 are proposed. Thus, the annual surface air temperature decreases by an average: of 0.69oС per 100 m of height above sea level, of 0.51oС with a shift of one degree of latitude to the north, and of 0.08oС with a shift of one degree of longitude to the East. The altitudinal and latitudinal gradients of temperature have the greatest spatiotemporal variability and the longitudinal gradient has the smallest one. These gradients generate "microclimatic noise" of temperature. On their basis, a regional semi-empirical model of the spatiotemporal distribution of the average monthly temperature for the plain part of Ukraine for the period 1991-2020 was worked out. A comparison of values of model average annual and monthly temperature for 58 meteostations in Ukraine with their actual values showed a statistically significant correlation. Additionally, validation of semi-empirical model average monthly temperature for 10 other stations was carried out.Item How to help Ukrainian scientists overcome Russia's invasion and advance sustainability(2023) Sotnik, Garry; Spinova, Yuliia; Sotnik, Tetiana; Polotska, Olga; Kysil, Oksana; Krakovska, Svitlana; Diachuk, Oleksandr; Bezvershenko, Yulia; Berezko, Oleksandr; Beldavs, Vidvuds; Andrusevych, AndriyRussia’s current invasion of Ukraine is devastating Ukraine and its people. As scientists living and working in Ukraine or working closely with Ukrainians, we see two critical paths through which the international science community and funding organizations can help Ukrainian scientists help Ukraine. One path involves supporting new partnerships between Ukrainian scientists, their international counterparts, and Ukrainian civil society and government. Such partnerships can help tackle the extreme challenges posed by the invasion as well as prepare Ukraine for sustainable recovery and development. The second path involves supporting the development of a new sustainability science curriculum in Ukraine to prepare local expertise for driving the country's recovery and development. Action now can help the Ukrainian science community overcome Russia’s invasion and, in the process, emerge more robust and better prepared to advance its country’s sustainable development.Item Monitoring and modeling of infrastructure indicators development of united territorial communities(2022) Horoshkova, Lidiia; Khlobystov, Yevgen; Shvydka, S.; Menshov, Oleksandr; Tarasenko, Denys; Sumets, A.A study of the dynamics of state support for infrastructure development of UTC, development expenditures (capital expenditures) and the effectiveness of the current mechanism for calculating the infrastructure subvention on the example of Zaporizhya region and identified the relationship between infrastructure subvention and development expenditures (capital expenditures). It is established that the current mechanism for determining the size of the infrastructure subvention, when it is determined depending on the size of the rural population and the area of UTC is ineffective. It is proved that it is necessary to assess the parameters of sustainable development of OTG not only by traditional components, which are economic, environmental and social, but also by the infrastructural component. For this purpose, an integrated indicator of sustainable infrastructural development of each individual UTC, district or region is proposed, which would allow comparing OTG indicators not only within a district or region, but also between regions of Ukraine. Its definition is carried out using the apparatus of fuzzy set theory.Item Change in the Water Surface Area of Reservoir of the Crimean Peninsula According to Radar Satellite data Sentinel-1 for the Period from October 2014 to August 2022(2022) Kuchma, Tetyana; Boychenko, SvitlanaAccording to Sentinel–1 radar satellite data, there is a tendency to reduce the area of the water mirror in all reservoirs of the Crimean Peninsula, analyzed in this study, compared to their water surface area in 2015. On average, the area of the water mirror decreased by 34% in 2021. In three reservoirs, the area of the water mirror decreased by more than 60% compared to 2015: Frontove, Taiganske, and Mizhhirske reservoirs. The tendency to reduce the water surface area begins to manifest clearly in mid–2019 and continues until 2021. Also, a retrospective analysis of satellite images for 2015–2021 showed that the Simferopol reservoir of water surface area had been reduced on average by ~ 20% compared to 2015. Changes in the Water Surface Area of Simferopol and Feodosiya Reservoir for the Period from October 2014 to August 2022 were presented. A retrospective analysis of satellite images for the period from March 2015 to August 2022 showed that the Simferopol and Feodosiya Reservoirs of water surface area had been reduced on average by ~20% and ~30% (according) compared to 2015.Item Soil sampling and magnetic susceptibility determination in soil science: methodological aspect(2022) Kruglov, O.; Menshov, Oleksandr; Horoshkova, Lidiia; Tonkha, O.; Andreeva, O.; Kruhlov, Bohdan; Zhuravel, O.The study is dedicated to the numerous methodological problems that arise when applying the magnetic susceptibility measurements of soils for the agrarian application. The experiment was carried out for the chernozem soils of the Kharkiv and Poltava regions. Problems in the sampling planning are related to the main tillage processes. The temporal and spatial parameters as well as the sampling depth were analyzed. It has been shown that the use of soil magnetic susceptibility (MS) has a high potential in determining soil inhomogeneities. The first of all, MS is relevant in the implementation of the concept of precision agriculture, where it has market advantages over traditional methods.Item Assessment of aridization of climatic conditions on the Crimean Peninsula in summer using ground and satellite data(2022) Boychenko, Svitlana; Kuchma, TetianaClimate vulnerability of the Crimean Peninsula is assessed based on the temperature and precipitation changes for the period 1991-2021 and satellite-derived drought index (VHI) variations for the period 2001-2021. There is an increase of temperature on average by 0.78±0.01 oC per 10 years in summer, and a slight change in precipitation in June and July (within 2±1%). While in August there is a decrease of the precipitation amount by 10-12%. According to analysed data, the most severe drought condition manifestation on the Crimean Peninsula over the last twenty years was observed in 2007, 2017, 2018 and 2020. In the central part of the Crimean peninsula, which belongs to the climatic zone of Steppe Crimea, arid conditions had the greatest manifestation and distribution (zones with extreme and severe drought conditions are observed). Minor areas in the mountainous part of the Crimea also have signs of arid conditions, but for the most part the condition of vegetation is satisfactory in this area. In percentage terms, in 2007 VHI values of extreme and severe drought occupied 57% and 20% of the peninsula’s area accordingly, as well 10% and 29% in 2017, 7% and 22% in 2018 and 11% and 26% in 2020.
