Food security strategies in the context of environmental and economic fluctuations in Ukraine

The study aimed to assess the impact of investments in agricultural technology on the productivity, economic efficiency and profitability of farming enterprises. The emphasis was on analysing yields of the three leading agricultural holdings in Ukraine: Svarog West Group, Stepova and Agroproduct LLC, which operate in different natural and climatic conditions. The methodology involved collecting data for three agricultural seasons (2021-2023), which was used to identify long-term trends and determine the impact of technology investments on key performance indicators of enterprises. A correlation analysis with the calculation of Pearson's coefficients was used to assess the relationship between agricultural technology expenditures and yields. The economic efficiency was calculated based on profitability and resource efficiency, which compared the results between agricultural holdings and identified management features in different conditions. The main results showed that investments in agricultural technology have a positive impact on yields, although their effectiveness depends on the specialisation of the farms and environmental conditions. For Svarog West Group, a strong correlation between investment and yield was determined (r = 0.85), which highlights the importance of technological innovation. Agroproduct LLC demonstrated the highest level of profitability (40%), which indicates effective cost management. In turn, Stepova achieved the highest efficiency of resource use (0.0056 t/thousand UAH) due to its specialisation in seed production. The results showed that it is necessary to combine technological innovation with adaptation to climate conditions to ensure the long-term efficiency of agricultural production. These findings can be useful for researchers, managers and practitioners involved in agricultural sector development and seeking ways to achieve food security in a changing climate
