Challenges in Assessing the Level of Plant-Based Food Self-Sufficiency Using Publicly Available Data in the Regional Context of Slovenia

Abstract Methods for assessing regional food self-sufficiency are poorly developed worldwide, while knowledge of the characteristics of regional food self-sufficiency could help in designing more sustainable and resilient regional food systems. This paper addresses the challenge of defining and assessing food self-sufficiency at different geographical levels and provides a detailed presentation of the method for assessing the regional plant-based food self-sufficiency rate using publicly available data from administrative sources, taking the Slovenian development regions as an example. The results indicate the need to improve the reliability of the data used to identify the characteristics of regional food self-sufficiency and to a more effective coordination between existing agricultural databases.
