With the current conflict in Ukraine and food security now being a major political question (e.g., Aubert et al. 2022, Dankevych 2022a, Dankevych 2022b, Glauber & Laborde 2022), this briefing explains how organic contributes to sustainable food security, summarising the most relevant and recent scientific publications that critically assess the productivity and sustainability of organic farming methods. The rapid increase in the quantity of scientific literature on this topic reflects the growing importance of the sector as well as the need for accurate summaries to inform policy makers. In 2020, 420,000 farmers in Europe (almost 350,000 in the European Union) and 3.4 million farmers globally were certified organic (Willer et al. 2022), and thus had committed to sustainable farming practices.
