Climate change and food production are reshaping global aquatic systems in ways that demand closer scrutiny and more responsible action. Climate change is already altering Mediterranean fish distributions, with many species shifting south-westwards and into shallower waters (pages 18–19). Nearly half of commercially important species are affected, disrupting marine ecosystems and fisheries. These changes highlight the growing urgency for climate-adaptive management strategies that are responsive to regional dynamics and capable of safeguarding both biodiversity and livelihoods.

 

At the same time, the expansion of aquaculture—often promoted as a solution to food security—presents its own set of challenges (pages 6–7). The sector continues to rely significantly on wild-caught fish for feed, while increasingly turning to terrestrial crops. Rather than reducing environmental pressure, this transition often redistributes it between marine and land-based ecosystems. Revised assessments indicate higher levels of resource use than previously understood, raising important questions about sustainability claims.

 

Together, these developments underscore the need for more transparent, science-based approaches to managing aquatic food systems.

 

Only by recognising the full environmental cost and embracing adaptive strategies can the sector move towards genuinely sustainable and resilient production.
