The research is devoted to theoretical and applied organizational grounds for evaluating the effectiveness of public administration in the region in the context of the Sustainable Development Goals. The purpose of the article is to substantiate and improve methodological approaches to assessing the effectiveness of public administration in the region in the context of the Sustainable Development Goals. The article tests the authors' hypothesis on the adequacy of substantiation of methodological approaches to assessing the effectiveness of public administration in the region, which leads to the significant implementation of the Sustainable Development Goals. The dependence of the calculations on the selected system of indexes and indicators that determine the current profile of the region is confirmed, it illustrates the state of the economy, human development and environmental safety relative to the reference (average, target, maximum possible under these conditions) state and vector, and also characterizes the direction and speed of the region towards the implementation of the Sustainable Development Goals. It is determined that the largest vector length is in Kherson region, which indicates that in the region on a number of economic indicators achieved higher results during the study period than in other regions of the Black Sea region and on average in other regions of Ukraine.

The article aims to analyze the potential of organic production in Ukraine in war conditions and determine its consequences for world food security. Methodological approaches based on cluster and rating analysis of regions based on their potential in the field of organic production are proposed and provide an appropriate evaluation algorithm, mathematical tools, and strategic alternatives for all variants of data obtained in the calculation process. With the help of the given methodological approaches, the development of strategies for organic production for the primary clustering of regions, namely in Kyiv, Odesa, and Cherkasy oblasts, is proved. The system of forming a regional model of organically oriented multidisciplinary agriculture is appropriate for these regions. This will create the preconditions for organic food production, organic livestock, and related sectors of environmentally oriented economic activities. The development of an innovative component for implementing SMART-specialization projects is possible. It is substantiated that the most affected regions (Kharkiv, Luhansk, Donetsk, Kherson, Mykolaiv, Zaporizhia) from hostilities and occupation are potential for organic production and have significant areas for agricultural production. It is projected that the other war in Ukraine will reduce the production of farm products, including organic, which will lead to food security in most countries.

The article aims to develop methodological approaches to assessing the environmental security of territories, identifying the regions most affected by hostilities, and substantiating the strengths of strengthening during the war. Methodical courses are offered, and the corresponding express analysis of the balance of economic, social development and ecological safety of regions of Ukraine based on the related indicators is carried out. The results on a ten-point scale characterizing the standardized deviations of the above indicators from the median value by region showed significant imbalances in achieving the vectors of sustainable development. That is, implementing one or two vectors is currently carried out by neglecting others, which confirms the urgent need to find mechanisms for their effective balancing. It is determined that during the war in Ukraine, the strategic task of the state was to develop guidelines for strengthening environmental security due to significant destruction of infrastructure and ecosystem damage. Among the main strategic approaches for strengthening are identified: identification of settlements and areas in need of humanitarian demining, marking of dangerous sites, cleaning (demining) of territories, involvement in the elimination of the consequences of hostilities and emergencies of international aid, and others.

The article reveals international challenges, national guidelines, and regional peculiarities of SMART specialization in tourism and recreation. In the course of the research, we offer methodical approaches to justify the SMART specialization of the region in the field of hospitality and recreation as a component of the general model of strategic development of the regional economy and a key factor of competitiveness. The authors determined that an effective tool for the strategic development of the region and the formation of sustainable competitive advantages, which has proven its effectiveness in the practice of regional management in the EU countries, is the definition of the critical SMART specializations of the region and the concentration of efforts on their development—using the proposed methodological approaches. Zakarpattia tourism and recreation spheres were tested for the conditions of adaptation of smart specialization. The calculations showed that the sphere of tourism, recreation, and hospitality as a whole is an essential branch of the economy of the Zakarpattia region and can develop based on SMART specialization. The key areas of tourism and recreation development in the regions that correspond to modern world trends and are the most relevant given the current military events are highlighted: green tourism, health resort, sports, rehabilitation, and inclusive tourism.

THE IMPACT OF DIGITIZATION ON THE SERVICE SECTOR DEVELOPMENTEvery day, the service sector is becoming more and more important for the economic development of many countries. The transition of the world economy from agriculture to machine production took place over many centuries, but the development of the service sector is much faster. The world is in the midst of radical changes, which indicate an increase in the influence of the service sector and the digitalization processes of many industries. The level of the service sector development affects the quality of life of the population. In many countries, the volume and composition of service services is constantly increasing and expanding.The service sector is also distinguished by a different nature and structure of investments, a different composition of the workforce (more than 2/3 of finance and labour are involved in the service sector). In recent decades, there have been not only shifts in the sectoral structure of the world economy, but also a significant increase in the share of the population employed in the production of services. In many countries of the world, this indicator exceeds the corresponding value for industrial production. Thus, the largest share of people employed in the service sector in 2015 was in Luxembourg (80% of the employed population), the USA (79%), the Netherlands (77%), Great Britain (76%), Sweden (76%), Australia (75%), Canada (75%), France (74%), Belgium (73%), Denmark (73%) and some other countries [1].Digitalization has had a large-scale impact on service enterprises and has completely changed them in many types of services. As part of the digitization of the service economy, the key approaches to customer service are changing:-with the help of digital Internet technologies, the client finds the service he needs and its provider;
