<p>The current patterns estimation of the water regime under climate change is one of the most urgent tasks in Ukraine and the world. Such changes are determined by fluctuations in the main climatic characteristics - precipitation and air temperature, which are defined the value of evaporation. These parameters influence on the annual runoff distribution and long-term runoff fluctuations. In particular, the annual precipitation redistribution is reflected in the corresponding changes in the river runoff.<br>The assessment of the current state and nature of changes in precipitation and river runoff of the Siverskyi Donets River Basin was made by comparing the current period (1991-2018) with the period of the climatological normal (1961-1990).<br>In general, for this area, it was defined the close relationship between the amount of precipitation and the annual runoff. Against the background of insignificant (about 1%) increase of annual precipitation in recent decades, it was revealed their redistribution by seasons and separate months. There is a decrease in precipitation in the cold period (November-February). This causes (along with other factors) a decrease in the amount of snow and, accordingly, the spring flood runoff. There are frequent cases of unexpressed spring floods of the Siverskyi Donets River Basin. The runoff during March-April (the period of spring flood within the Ukrainian part of the basin) decreased by almost a third.<br>The increase of precipitation during May-June causes a corresponding (insignificant) increase in runoff in these months. The shift of the maximum monthly amount of precipitation from May (for the period 1961-1990) to June (in the current period) is observed.<br>There is a certain threat to water supply in the region due to the shift in the minimum monthly amount of precipitation in the warm period from October to August. Compared with October, there is a higher air temperature and, accordingly, higher evaporation in August, which reduces the runoff. Such a situation is solved by rational water resources management of the basin. The possibility of replenishing water resources in the basin through the transfer runoff from the Dnieper (Dnieper-Siverskyi Donets channel) and the annual runoff redistribution in the reservoir system causes some increase in the river runoff of summer months in recent decades. This is also contributed by the activities of the river basin management structures, which control the maintenance water users' of minimum ecological flow downstream the water intakes and hydraulic structures in the rivers of the basin.<br>Therefore, in the period of current climate change, the annual runoff distribution of the Siverskyi Donets River Basin has undergone significant changes, which is related to the annual precipitation redistribution and anthropogenic load on the basin.</p>

It was established that 17008 HFRS cases were reported in 53 (out of 54) administrative districts and 12 cities (out of 14) of the Republic of Bashkortostan in 2009-2018. The most intense epidemiological situation (a long-term incidence rate of 48,5 per 100 thousand of the population) was observed within the boundaries of the forest-steppe landscape zone, where. more than 86 % of all cases of infection are recorded of the Republic of Bashkortostan in 2009-2018. The share of infections among the urban population was 64.0 %, the rural one – 36.0 %. In the long-term aspect, according to the conditions of HFRS acquisition, short-term visits to the forest area prevailed – up to 80 %, in household settings – up to 14 % of all cases of the disease. Seasonal increases in the incidence of HFRS take place in May-June – up to 15 % and in September-December – over 46 % of the annual incidence. The presence of synchronicity in the dynamics of HFRS morbidity in rural and urban populations within the boundaries of the administrative district was detected. It has been substantiated that in order to reduce the level of HFRS morbidity among the rural and urban population, it is necessary to provide for an increase in the volume and frequency of preventive (anti-epidemic) measures in the vicinity of rural settlements, regional centers, urban-type settlements and large cities located near forests, within the boundaries of the entire area of the administrative district.

<p>In many regions of the world, water supply is threatened by natural hazards such as floods and droughts, as well as by shocks induced by anthropogenic changes to water use. Lack of anticipation and/or preparation for these events can lead to delayed or insufficient responses to sudden or developing water crises, that sometimes can produce irrecoverable damage to the environment. In this work, a socio-hydrological approach to sustainable water resources management of the Alcantara River Basin in Sicily (Italy) is adopted that explicitly takes into account feedbacks between the natural and the human components that might arise from shocks to the water management system, including possible evolution of policy responses. The Alcantara River Basin is a groundwater-fed catchment which supplies many villages on the Ionian coast up to Messina city, mainly through the Alcantara aqueduct, but also agricultural areas and industries, including hydropower plants. It also hosts the Alcantara Fluvial Park, an important natural reserve. The Alcantara aqueduct also supplied the city of Messina during a temporary failure of its main aqueduct caused by a landslide in October 2015. The main purpose of the work is to use the socio-hydrological model as a “screening tool” to frame water resource management issues in a broad way and provide guidance to the community to identify aspects of societal behavior that need to evolve towards sustainable water resource management in order to withstand future shocks. This has been done by scenario simulations in conditions of a natural shock affecting the system (i.e. drought) and of a human-induced one (i.e. increase in groundwater extraction). Sensitivity analysis of the model social parameters revealed how the value attributed by the society to the environment and water resources use, its capacity to remember previous water crises and, in particular, its previous responses to shocks, can affect the system in a way that can produce paradoxical effects. Results show how a rapid decision-making strategy that may work in the short term, can be counter-productive when viewed over the long term and how a do-nothing decision during a water crisis could be highly damaging to the environment. For the above-mentioned reasons, this socio-hydrological approach can be considered as a useful tool to understand human-water dynamics and to support decision-makers in water resource management policies with a broad and long-term perspective.</p>

According to the results of 2020, in the rating of the subjects of the Russian Federation for the production of gross agricultural output, the Republic of Bashkortostan came in 6th place and 2nd in the Volga Federal District. The long-term leadership of the republic in terms of the development of the agro-industrial complex is largely explained by the presence of large areas of agricultural land (more than 7.2 million hectares), sufficient labor resources and relatively favorable soil and climatic conditions for the development of many branches of agriculture. However, in the XXI century, without the introduction of agro-innovations and the development of high-tech agriculture, processing industry, an effective system for the sale of manufactured products, it is becoming increasingly problematic to ensure the long-term competitiveness of the agro-industrial complex of the region both at the All-Russian and global levels. Current trends in the development of agribusiness in the world and in our country clearly show the priority of using the latest achievements of scientific and technological progress and significant investments in new agricultural technologies at the regional level in order to ensure high quality products and compete with domestic and foreign companies. Within the framework of this study, the need to improve the interaction of agribusiness with the scientific and educational sphere and the formation of the regional innovation infrastructure of the agro-industrial complex in the Republic of Bashkortostan with the coordinating role of the Ufa Federal Research Center of the Russian Academy of Sciences and the Government of the Republic of Bashkortostan is actualized. The authors conducted a comprehensive analysis of the key problems in the creation of a regional agro-industrial scientific and production cluster in the Republic of Bashkortostan and outlined priorities in its development.

The article reveals the main characteristics of the change in the values of the river runoff layer indicator in the long-term section across the territory of the Republic of Bashkortostan. In previously published works related to 1990-2000, the statistical parameters of river runoff are considered without taking into account the changes that have occurred in the general population of the initial information. It is noted in the article that the calculations and estimates for the study of the peculiarities of changes in hydrometeorological conditions, carried out by us in recent years, indicate a violation of the homogeneity of the observation series. At the same time, attention is drawn to the fact that this trend is dependent on the influence of factors associated with global climate change. The article indicates that ignoring the facts reflecting the ongoing changes can affect not only the accuracy of the calculations, but also lead to the adoption of incorrect and unjustified decisions in the water sector and the assessment of environmental conditions in watercourses. The analysis was carried out according to the values of the annual runoff layer, the change in the indicators of the annual runoff of the rivers of the republic was calculated for two time intervals. As the boundary conditions between them, the year was taken, from which a rather clear tendency of the trend change in terms of the annual runoff values is revealed. Cartographic analysis of the information obtained was carried out using the ArcGIS software package. It has been established that during the period of noticeable climatic changes in most of the territory of the republic, there is a tendency to an increase in the values of the annual runoff layer. At the same time, the greatest indicators of change occur on the western slopes of the Southern Urals and the Ufa plateau within the republic. It was found that a noticeable decrease in the values of the annual runoff layer is observed over the territory of the Bashkir Trans-Urals.

Abstract. The article actualizes the need of foresight technologies in the sustainable development of strategic plans of sustainable development in rural municipalities at the level of the Russian Federation. It is pointed out that the modern methodology of foresight studies is quite flexible and multifaceted, has wide application at different hierarchical levels of management. The purpose of the study is to prove the need to use the foresight methodologies for rural development strategic planning and forecasting tool. In the course of the study, the following methods were used: strategic planning and forecasting, foresight technologies (expert survey and expert opinions), comparative analysis. The scientific novelty of the study is determined by the formation of a set of practical recommendations on the use of foresight tools at the municipal level of management in rural areas. The systematic approach usage in combination with foresight technologies allows to develop strategic plans for the development in rural areas from the perspective of long-term improvement of their economic and social component. A brief analysis of the current state and development of foresight research in the Russian Federation is presented. It is concluded that in modern conditions of rural development it is necessary to develop strategic programs and anti-crisis measures that should focus on the application of the foresight technologies. It shows that the characteristic features of the rural municipal foresight are, on the one hand, the obligatory interconnection of strategic priorities for rural areas development in the long term and, on the other hand, the need to achieve the interest of key factors in regional development. Results of a research: the algorithm of strategic planning of sustainable development of rural areas of the region based on foresight technologies and the mechanism for its implementation at the municipal level are considered; strategic goals and priority areas for sustainable development of rural areas of the Republic of Bashkortostan in the sub-regional context were defined. On the basis of the foresight analysis, a three-level branding of agri-food products manufactured in the region was carried out, and brands within the considered rural municipalities were identified. It is concluded that foresight technologies should be used as the system tool for the formation and implementation of sustainable development strategy in rural areas of the Republic of Bashkortostan.
