The rivers of Europe are becoming increasingly salty, a phenomenon attributed to human activity. This situation represents a growing threat to aquatic ecosystems and to the uses that depend on these water resources.
In Portugal, the areas of Santarém and Baixo Alentejo are among the most concerning, with river salinity having doubled in the last ten years. This significant increase raises alerts about the impact on agricultural activities and local biodiversity.
Spain is among the most severe cases in the European Union regarding the increase in river salinity. The phenomenon affects several European countries, although the article does not specify other concrete examples beyond Portugal and Spain.
