Рассмотрены пространственная и временная динамика развития гидроэкологической ситуации в бассейне р. Тихая Сосна на территории Белгородской и Воронежской областей на фоне реализации программ развития интенсивного животноводства. Выявлены два основных фактора формирования гидроэкологической ситуации в бассейне р. Тихая Сосна: сокращение численности сельского населения и успешная реализация программ развития интенсивного животноводства. Экологическая ситуация для реки Тихая Сосна может оцениваться как умеренно напряженная: при сохранении структуры и облика водных экосистем периодически наблюдается сверхнормативное загрязнение водной среды такими биогенными компонентами, как соединения азота, фосфора, БПК5. Картографированы места размещения производственных площадок животноводческих комплексов и ферм на территории Волоконовского, Алексеевского, Красногвардейского, Новооскольского, Чернянского, Красненского районов Белгородской области и Острогожского, Лискинского и Каменского районов Воронежской области. Определена геохимическая нагрузка для реки Тихая Сосна по показателям содержания соединений азота, фосфора, меди, железа и др. и проведён статистический анализ показателей содержания загрязняющих веществ в р. Тихая Сосна по данным Росгидромета.

“…Therefore, the active influence of natural and economic factors on the rivers of this class manifests itself more clearly and faster than is observed in large rivers. For this reason, it is considered that small rivers are more sensitive and, therefore, more vulnerable to anthropogenic impacts [4][5][6][7]. The river basins most developed in agriculture are distinguished by the most significant changes in water and sediment discharge, as well as the intensity of erosion in their basins [8].…”

The basin of the small river studied here (the Vezelka River, Belgorod Oblast of European Russia) is located within an urban area (22% of the basin). This circumstance determines its specificity as an object of synergetic anthropogenic impact. The purpose of the work was to develop and test approaches to the integral assessment of the hydroecological situation both in the watershed and riparian zones based on hydrological, hydrochemical, and hydrobiological data and estimates of soil erosion, river water quality, and the pollution of river bottom sediments. The selection of the Vezelka River and its watershed for the study was due to the presence there of two water intakes for a town with a population of 2439 people per sq. km, repeated bottom deepening in the riverbed, and the fact that there is a single regional small-river hydrological station (although there are 567 rivers < 25 km long in Belgorod Oblast). Analysis for 1951–2021 showed a steady decline in water discharge since 1991; thus, over the past three decades, the discharge has decreased by 2.4 times. The reduction in the length of the river network of the study region by 38% over the past 250 years and the assignment of water (at 10 gauging stations) to 3–4 quality classes (extremely and heavily polluted) indicated the exhaustion of the possibilities for the self-purification of the river water. These estimates for large and medium rivers were clearly confirmed by the investigation of the water in the small river studied. In the summer low-water periods, the maximum allowable concentrations in fishery water bodies were exceeded by 2–10 times in terms of Cu, Fe, ammonium, oil, and biochemical oxygen demand. The reconstruction of the floodplain–channel subsystem of river–valley landscapes was substantiated as the final stage of the concept of basin nature management, replacing the continuous deepening of the channel without proper erosion control measures in the watershed area and the organization of buffer zones along the river banks.

“…Particularly negative manifestations of anthropogenic and climatic changes are concentrated in the Steppe zone (Lisetskii et al 2016). The level of water resources supply and their quality has decreased significantly (Pichura et al 2018), the natural water network of small and mediumsized rivers has been destroyed by 60% (Oti et al 2020, Lisetskii 2021), the frequency of droughts has increased (Assan et al 2020, Ukrainskiy et al 2020) and manifestations of erosion processes (Dudiak et al , 2020, the state of land resources deteriorated (Breus et al 2019, which led to a decrease in the yield of agricultural crops (Domaratskiy et al 2020, Vdovenko et al 2022. In order to increase the level of management efficiency in the agrarian sector of the economy (Vdovenko et al 2015, Mayovets et al 2021, it is necessary to substantiate environmental protection measures for the restoration and rational use of natural resources, to ensure the implementation of the principles of sustainable nature management, taking into account the spatio-temporal patterns of changes in climate and the bioclimatic potential of the territory.…”

To increase the level of management efficiency in the agricultural sector of the economy, it is necessary to substantiate environmental protection measures for the restoration and rational use of natural resources, to ensure the implementation of the sustainable environmental management principles, considering the spatio-temporal patterns of changes in climate and bioclimatic potential of the territory. Using the methods of multivariate statistics and time series forecasting, regularities of changes in climatic conditions in the Steppe zone of Ukraine for 1945-2019 were established, and a forecast of changes in the bioclimatic potential of the region until 2030 was made. It was established that during the research period the average annual air temperature increased by 3.5 °C. The amount of annual atmospheric precipitation varied within 186-778 mm with a variation level of 27.2%, in the last 20 years it was determined to decrease by 40% -to 500-300 mm. It has been proven that the inertial probability of repeating hot years is estimated at 0.58, and the possibility of repeating wet years at 0.46. As a result of forecasting, it was determined that if the trend of climatic conditions is maintained, there will be a stable trend-cyclic increase in the average annual air temperature by 0.06 °C per year and a decrease in the amount of annual precipitation by 62.0 mm per year. This resulted in an 18.7% increase in solar radiation on the soil surface and a 26.0% decrease in climatic losses on soil formation, which reduced the rate of the natural ability to reproduce soil fertility. In particular, the bioproductivity of plants decreased by 62.0%, and the probability of its further decrease by 20% is predicted. Over the past 20 years, the coefficient of natural humidification has decreased by 66.4%, and it is predicted to decrease by 20%. The obtained results confirm significant climatic changes and their negative manifestations on the reduction of bioclimatic potential in the Steppe zone of Ukraine, the deterioration of agricultural production conditions, the reduction of harvests, the self-regenerating and self-regulating function of steppe soils.
