The role of the fishery industry in the shift towards sustainable food security: a critical study of blue food

Blue foods have traditionally been undervalued in their contribution to global food systems. Yet they are incredible sources of locally produced nutrition for millions of people. In late 2022, there was a call for global action on food system transformation in the United Nations Food Systems Summit. The Blue Food Assessment, a scientific assessment of blue foods and their potential to contribute to sustainable and just food systems, reveals gaps where innovation could meaningfully bolster the blue food ecosystem. This article aims to examine the dynamic impact of the fishery sector on long-term food security in 27 European Union (EU27) countries while considering the contribution of agricultural output, energy production, economic development, and governance between 1990 and 2022. The findings showed a substantial positive link between fishery production and sustainable food security at a 5% statistical level, except the fifth quantile, using the new method of moment quantile regression (MMQR) with fixed effects. From the first to the ninth quantiles, fishery output considerably improves sustainable food security, with a more substantial benefit at the highest (≈ 0.021) and a lower impact at the lowest quantile (≈ 0.010). The findings also show that the EU13 developing countries see a more significant positive impact, at a 5% statistical level, on sustainable food security from fishery output than the EU14 developed nations. On the other hand, the findings also show that the EU14 developed countries see a more significant positive impact, at a 1% statistical level, from the agricultural output on sustainable food security than the EU13 underdeveloped nations. The results show a strong positive correlation between agricultural production and long-term food security at the median and most recent quantiles (≈ 0.362). In the EU27 area, sustainable food security rose across median and recent quantiles, supporting the growth hypothesis for nations that produce fisheries. In the EU27, the impact of governance was positive and statistically significant at 5% for both older and more recent quantiles. The findings also show that the EU14 nations have a more substantial beneficial effect of governance, at a 1% statistical level, on sustainable food security than the EU13 countries. With the help of effective fishery sector production, policymakers may raise the degree of food security in the EU14 and EU13 nations and ensure long-term food security.
