Changes in the ecological conditions of the cultivated coenosises caused by anthropogenic load have been shown by the example of several of the largest botanical gardens in Ukraine. That complex influence leads to the transformation of coenosises at stages II and III of anthropogenic degression. Changes in phyto- and avidiversity compositions have been shown using a transformation gradient. Positive correlations between compositions and diversity indices of bird communities and vegetation composition (diversity indices, dominance indices, evenness indices) have been detected. The values of the phytodiversity indices showed greater deviation from the normal conditions.

Research needs of adaptation mechanisms of invasive alien species arises in connection with the naturalization of species of the genus Parthenocissus Planch in forest ecosystems of Ukraine. The results showed that P. quinquefolia has a wide range of values of edaphic and climatic factors. The populations of P. quinquefolia differ according to the degree of anthropogenic transformation of the ecotope, the ecological conditions formed, and the allocation of coenotics. The biomorphological characteristics of the species variability are shown on the gradient of anthropogenic transformation. Diagnostic parameters of P. quinquefolia under the conditions of anthropogenic transformation are the number of crotches of the tendrils and the length of the tendrils. The number of flowers per plant is characterized by the highest level of variation and belongs to the V class of variability. The smallest plasticity is characterized by the diameter of the stem. Vitality analysis indicated that cenopopulations of P. quinquefolia belong to the equilibria or prosperous population types, regardless of the intensity of the anthropogenic factor.

Official international organizations claim that existing notions about the relationship between a decrease in life expectancy and a reduction in population in affected regions are controversial and are a result of the impact of radioactive emissions from the Chornobyl explosion. However, despite the weak link between the level of radioactive contamination and population dynamics in the studied areas, the level of natural decline in rural population on radioactively contaminated land is significantly higher than in other territories. This indicates the need for further research in this direction. The aim of the study was to clarify the social basis for the implementation of balanced development in radioactively contaminated areas of Ukrainian Polissia. The article presents the results of a study on the role of the social component in the implementation of sustainable development in radioactively contaminated areas of Ukrainian Polissia, taking into account both long-term complex ecological, economic, and social challenges and the potential consequences of Russian military aggression. The methodology of the research is based on a systemic approach, which involves using both modern and classical scientific methods of research, including general scientific methods such as data analysis and synthesis; retrospective and comparative analysis for identifying causal relationships; analytical and synthetic methods for studying scientific and statistical data, archival materials, legislative and regulatory documents, among others; and mathematical methods for the mathematical processing of the obtained results. The research is based on the official statistical data provided by the main statistical departments in Volyn, Zhytomyr, Kyiv, Rivne, and Chernihiv regions. Existing trends and results of studies on the interrelation between radioecological and social components have been analyzed. The study examines social indicators of the quality of life of the inhabitants of Ukrainian Polissia region (total income, level of wages, structure of population expenditures, etc.), demographic indicators (population, gender-age structure and population growth/decline), employment rate, morbidity, and consumer basket for rural and urban settlements in the studied regions. It has been established that indicators of the social sphere in the region of Ukrainian Polissіa can serve as additional criteria for assessing the current socio-economic situation and its dynamics. It has been determined that the social factor is an integral component and at the same time a criterion for sustainable development of radioactively contaminated territories. The need for a series of measures aimed at increasing the effectiveness of the state policy on employment of the population and the vocational education system has been proven, taking into account the forecasts of the regional enterprises’ demand for certain skilled personnel by professions and specialties, as well as the list of the most in-demand and promising professions and specialties. The list of such professions is individual for each region

The article provides a comprehensive analysis of retrospective prerequisites for the restoration of radioactively contaminated lands in Ukrainian Polissia on the basis of sustainable development principles. The research methodology is based on a systemic approach, which involves the use of modern and classical scientific methods: general scientific methods (analysis and synthesis of data); retrospective and comparative analysis (identification of cause-and-effect relationships); analytical-synthetic (study of scientific and statistical data, archival materials, legislative and founding documents, etc.); mathematical (mathematical processing of obtained results). The research is based on official statistical data from the main statistical offices in Volyn, Zhytomyr, Kyiv, Rivne, and Chernihiv regions. The aim of the study was to outline the socio-economic prerequisites for sustainable development of radioactive contaminated territories in Ukrainian Polissia. The study analyzed the state of economic development in Ukrainian Polissia, including the agricultural and forestry sectors, as well as the social component as a factor and indicator of sustainable regional development. Additionally, the study analyzed the housing conditions and income level of the population in the radioactive contaminated territories of Ukrainian Polissia. It has been established that the ecological factor has a significant impact on the socio-economic situation in Ukrainian Polissia, particularly when analyzing the impact of the radiological factor. The study shows that despite the leading positions of the agricultural and forestry sectors in the region, they have not been able to fully recover after the Chornobyl disaster and the post-Soviet economic crisis, which has led to negative social consequences. To address existing problems, the state employment policy should be focused primarily on preventing crisis situations and stimulating the return of migrants. Additionally, reform of economic specialization should be envisaged, taking into account regional specificities and introducing innovative technologies and solutions that would enable the attraction of investments.
