From 2019 to 2022, since the outbreak of the COVID-19 pandemic, the global percentage of hunger rose by 150 million people, which is 10% of the world population. At the same time, one-third of food is thrown away because it cannot reach the final consumer. Climate change, natural catastrophes, wars leading to humanitarian crises are the main and ongoing causes of hunger. COVID-19 acted as an accelerator of processes that exacerbate the food security crisis, to which import-dependent countries are especially sensitive. Quarantine that was introduced as a tool to combat the spread of the COVID-19 acted as a catalyst of social, economic, political, ecological, and food crisis that is displayed in the global economic system and in agriculture – its subsystem. At first glance, the increase in the percentage of starving populations on the planet is explained by poverty and the inability to purchase basic food products; a rise in prices was caused by breaks in logistics chains, the increase in the price of energy carriers, and economic shifts caused by the lockdown. In practice, despite the constantly growing volumes of global production of agro-industrial products, the balance between demand and supply of products that ensure the world's food security has been disturbed. The research problem lies in the insufficient determination of intangible causes of hunger, other than those caused by poverty and social inequality. The aim of the research is to show the prospects of the aggravation the food security crisis due to excess of food demand over supply, and to propose theoretical ways out of the crisis. The quantitative method of panel data research was used to prepare the article. The visualization method was used to simplify the perception of the proposed array of information. It is possible to overcome such social problems as hunger, poverty, climate and ecology problems caused by the increase in the temperature on the planet's surface, ocean pollution, and soil degradation only through adaptation and achieving synergy between the planet’s ecosystems. Agriculture as a main factor of food security should be transformed through implementing principles of climate-optimized agriculture and blue economy (use of ocean resources) as a source of “blue food” to achieve food sustainability.

The research subject of the paper is the process of capital adapting. The purpose of the article is to present capital as a multifunction dissipation system, which consists of the number of interconnected subsystems that operates being under the influence of destabilizing socio-economic factors. There is still no explicit definition of economic adaptation, and capital is not regarded as a set of tangible and intangible assets. Taking into account that the current operating environment, at both the macro and micro levels, may be characterized as unsustainable, and each system strives to organize itself to achieve the main objective, it is worth considering the process of adaptation, using a synergistic approach. This requires looking at the concept of capital as a multifunctional system, firstly, identifying which economic categories are made as subsystems of capital and which of them form capital, secondly, assessing potential areas of adaptation, thirdly, and identifying where adaptation can be targeted in the first place, fourthly. Determination of priority goals is the task of rapid financial analysis, using the results of strategic analysis it is possible to determine long-term goals of adaptation. Methodology. The article uses methods of empirical knowledge aimed at structuring approaches to the concepts of capital, their selection and analysis. Based on the empirical research, theoretical studies have been carried out. It was used such methods us analysis and synthesis, deduction, abstraction and generalization. The conceptual framework is based on the theoretical developments in various scientific fields that have studied capital, the enterprise, the economic system as an economic category, the concept of adaptation, synergies in the economy, and methods of strategic and financial analysis. By examining and analysing existing approaches to the listed issues, it has become possible to propose a definition of capital adaptation as a multifunctional dissipation system. As a result of the research, it became clear that for sustainable adaptation, it is advisable to use the tools of strategic management, and for instantaneous adaptation tools to ensure the economic and financial security of the enterprise. In the process of writing this research, it became clear that it was necessary to study issues related to the characteristics of subsystems, their assessment and analysis in order to make the adaptation process more multifaceted and effective.
