Climate Change Threatens Mediterranean Fisheries With 41% Drop in River Flow
A new study by European scientists warns that freshwater flowing through rivers into the Mediterranean Sea could decline by as much as 41% due to climate change. The research, published on February 3, 2025, outlines a worst-case scenario in which global temperatures rise by 4°C above pre-industrial levels, drastically altering coastal ecosystems and threatening the region’s fisheries.
The decrease in river flow would reduce freshwater and nutrient inputs, leading to lower primary productivity in the Mediterranean’s marine ecosystem. This would have cascading effects on the food chain, ultimately impacting commercially valuable seafood species.
"The results show that 41% less river flow could slash marine productivity by 10% and fish biomass by 6% in the Mediterranean, leading to annu...
