Purpose: This scientific study explores the potential for collaboration between Poland and Ukraine to enhance the supply of plant-based food products in Poland. By leveraging the agricultural resources and expertise of Ukraine, this partnership aims to identify and cultivate new plant varieties that can be grown on Ukrainian soil and exported to EU countries. The research focuses on analyzing the suitability of Ukrainian soil for growing specific crops, assessing market demand, and evaluating the potential economic and environmental benefits of such cooperation. Design/methodology/approach: The study involves a comprehensive review of scientific literature, agricultural research, and market analysis to identify promising crops with nutritional value, high productivity, and adaptability to various climates and growing conditions. The findings offer insights into the diversification of food production systems and the promotion of sustainable diets. The methodology was based on the official data of Statista published in 2010-2023. Combining multiple methods provided a more comprehensive and nuanced understanding of the complex interactions between plant-based nutrition development and ensuring food security for the population. Findings: The findings contribute to the development of sustainable agriculture practices, food security, and economic growth in both Poland and Ukraine. The authors investigate the potential of cultivating novel plant varieties to ensure an adequate food supply for the population. By exploring diverse crops beyond conventional staples, such as asparagus, this research aims to identify new plant species and varieties that can contribute to sustainable agriculture and meet the evolving dietary needs of the population. Research limitations/implications: The implications of this study underscore the importance of stakeholder engagement and adaptive management for effective integration. Practical implications suggest the need for policy coordination, capacity building, and innovative incentive mechanisms to foster harmonious coexistence between plant-based nutrition development and ensuring food security for the population. Originality/value: The value of the article is in the analysis of key factors influencing the impending crisis and analyzes its potential implications on food availability, affordability, and access. The findings suggest that the growing demand for food, coupled with various environmental, economic, and policy challenges, may lead to significant food supply disruptions and pose serious threats to the well-being of citizens in the region. These results could be especially interesting for researchers whose studies are interdisciplinary. This investigation examines the potential emergence of a food security crisis in Poland and other European Union (EU) countries. (original abstract)
