Modern trends of agro-food provision are summarized with the systematization of the factors of external and internal environment, which affect the innovativeness of agro-food chains. The tendencies are highlighted and the transformational processes in the agrarian sector of Ukraine, which conditioned the destruction of eco- nomic relations and the breakdown of technological links of agro-food chains, the deterioration of the indices of safety and quality of agricultural raw materials and fi nal food products, are disclosed. The challenges for the functioning of dairy products chain are analyzed with the substantiation of the fact that the process of introduc- ing the complex of innovations and systemic methods of safety should cover all the actors involved, all the sec- tors and elements of production which ensure the safety and quality of agricultural raw materials and fi nal food products. It was proven that the trends of using innovations in the dairy farming should be the achievements in the fi eld of selecting cattle and fodder crops, modern technologies of forming and restoring the livestock to provide for the increase in its resistance and competitiveness. It was substantiated that it is an urgent issue for milk processing enterprises to implement technological innovations and to form long-term partnership relations with the suppliers of raw materials in order to diversify their product portfolio and offer quality and safe dairy products. It was substantiated that the functioning of agro-food chains will be conducted under the impact of environmental challenges which requires creating the conditions and prerequisites for a higher level of their flexibility to innovations, where the priority role should be attributed to state-private partnership in the elaboration and implementation of technologies.

The main systemic flaws and problems that led to the destruction of the planning and administrative model of the economy and the transition to a market, and in the agricultural sector were accompanied by a transformational recession in the 1990s and the emergence of recurrent agrarian crises in the future. It is established that the consequences of the decline in agriculture correlate with the scale of production by the capacity of the food industry, but with a shifted time frame. It was confrmed that, frst of all, the agrarian crisis covers agricultural production, and it further affects other branches and sectors of the agri-food complex. The peculiarities of the manifestation of agrarian crises of 2008-2009, 2014-2015 and 2020-2021 are revealed and the inter-crisis periods concerning the causes and consequences of noticeable fluctuations with the production of food enterprises are analyzed. It is established that the achievement of the pre-crisis (1990) level of food, beverages and tobacco products occurred six years after the "bottom" of the transformational recession, and agricultural products - twenty years later. However, the COVID-19 pandemic has caused a worldwide crisis and an agrarian crisis in Ukraine which resulted in signifcant weakening of resilience due to reduction in food production. In this regard, it was important to identify and assess the degree of key problems development the agricultural sector, on the progress of which in the face of increasing market turbulence and will depend on the sustainability of the food industry. The key components for preserving and strengthening the sustainability of the food industry for the current stage have been systematized, in particular, satisfying processing capacities in safe and high-quality food raw materials and carrying out innovative and technological modernization of food processing enterprises, completing national food security legislation of Ukraine on sanitary and phytosanitary measures for the protection of animals and plants to EU legislation. It is established that the implementation of HACCP in food industry is rather topical in the need for a comprehensive solution to a number of problems in the feed-food chain "from feld to table". It is grounded that the practical observance of hygiene, safety and quality requirements will ensure the safety of products of animal origin. It is revealed that market operators comply with the requirements of national regulations, which are harmonized with EU Directives, technical regulations, standards, guidelines of good practice, and implementation of basic principles, methodological approaches and regulations of the Community in the feld of domestic sanitation. phytosanitary measures, form a single regulatory feld of veterinary and phytosanitary requirements for feed market operators. As a result, a transition to a qualitatively higher level of requirements in the chain "from the feld to the table" will take place and ensure their continuity and increasing the level of compliance with safety and quality standards of livestock products. It is emphasized that the advancement of Ukraine's agricultural sector on the path of integration into the EU internal market is accompanied by the emergence of new differences and inconsistencies between domestic and European requirements, changes in the regulatory framework and their implementation in practice. This is an important prerequisite for providing processing facilities with safe and high-quality raw materials and the production of competitive products, which will contribute to increase the sustainability of the food industry. Key words: agrarian crisis, market turbulence, development trends, stability of the food industry, regulatory framework for the production of livestock products.

The article systematizes the methodological principles and highlights the priority areas of research in the agricultural sector of the economy, taking into account the factors of external and internal environment of its development. The key challenges facing the world and national agricultural sphere are analyzed and systematized, among which the starvation of a large part of the world's population and its poverty, which are also inherent in Ukraine, are considered in detail. It is emphasized that the common challenges of food security in the world and in individual countries imply differences in approaches to their solution. It is proved that solving problems and overcoming challenges is mediated through transformations and changes that have taken place and will continue to take place in the agricultural sector of Ukraine. The main ones are: global climate change, the COVID-2019 pandemic, elections to local governments, regional councils and councils of enlarged districts and local councils of united territorial communities, the opening of the land market, etc. The priority directions of scientific researches in the agrarian sector of economy are substantiated, which are first of all connected with the following tasks: food security, increase of stability in the conditions of development turbulence, maintenance of innovative and sustainable development, increase of competitiveness of agro-food chains, sustainable development of united territorial communities. agricultural production, improving the quality of the rural population life and others. It is established that modern science has formed a powerful methodological and methodological potential, which allows to successfully solve the problem of creating models to support decision-making on the strategic development of any economic system, including agricultural sector of the economy. It is argued that rational scenarios for the long-term development of the agricultural sector can be obtained only on the basis of a reasonable combination of different methodological approaches, models and methods of research in the agricultural sector. The main models of support and decision-making for the strategic development of the agricultural sector as a socio-economic system are identified: data analysis methods (Data Mining), scenario method, simulation models, Monte Carlo method, data mining methods, methods of intellectual and cognitive modeling. Keywords: agricultural sector, methodology, priority scientific researches, territorial communities, agriculture, food industry.

Класифіковано ключові проблеми вітчизняних агропродовольчих ланцюжків, які переважно сконцентровані у їх первинному сегменті, зокрема такі, як: правова неврегульованість економічних відносин, дефіцит сировини, незавершеність впровадження системних методів харчової безпечності, диктат підприємств-інтеграторів тощо. Встановлено, що розкрити внутрішній інноваційний потенціал агропродовольчих ланцюжків допоможе удосконалення організації, умов функціонування, інституціональних норм і неформальних правил, форм соціально-економічних відносин між акторами та членами їх колективів. З урахуванням зарубіжного досвіду обґрунтовано пропозиції щодо розбудови агропродовольчих ланцюгів з метою посилення їх сталості, підвищення ефективності та нарощування доданої вартості. К л ю ч о в і с л о в а : сільськогосподарські та переробно-харчові підприємства, агропродовольчі ланцюжки, сталий розвиток, ланцюжки доданої вартості.
