The purpose of the article is to actualize the challenges faced by Ukrainian agriculture in the context of climate change and the impact of the economic activity of enterprises on the state of natural resources, as well as to consider the ways and mechanisms of the post-war transition of Ukrainian agriculture to sustainable development. In the study, we used monographic, comparative analysis, empirical, abstract, and logical methods. The first consequences of climate change in agricultural sectors of the planet are characterized. Increasing temperatures to a maximum level, longer periods of extreme heat, more intense droughts, increased moisture deficit during the growing season, winter thaws, the spread of pests and diseases, and other manifestations of climate change have a negative impact on agricultural production. In the context of climate change, as highlighted in the paper, these negative processes will significantly intensify, requiring an immediate transition from ecologically and socially destructive monoculture to agroecological agriculture, which is recognized as one of the most affordable, low-cost, socially oriented, and environmentally relevant ways to transition to sustainable development of the industry. The principles and institutional support for such a transition are revealed, taking into account the expected climate change and post-war consequences for Ukrainian agriculture.

The purpose of the article is to analyze the impact of the openness of a company to stakeholders on the effectiveness of the business model of the enterprise. The hypothesis. We believe that conducting a socially responsible business, i.e., disclosing non-financial information about the activities of enterprises, leads to the improvement of their financial indicators and is therefore evidence of a more effective implementation of their business models. Methods of the study. The following methods were used in the study: analysis and synthesis, comparative, induction and deduction, scientific abstraction, decomposition and logical generalizations in the analysis of scientific literature; computational–analytical, diagnostic, tabular and economic–statistical methods to assess the effectiveness of the implementation of business models of enterprises; diagnostic, statistical, index, method of expert assessments and rating to assess the corporate sustainability and transparency of enterprises; the use of the method of integrated indicators allowed the grouping of enterprises by classes of efficiency of business models, corporate sustainability and transparency. According to results of the study, it was determined that an effective business model is formed on the basis of maximum transparency and corporate sustainability in conditions of unpredictability and instability of the external environment.
