Short summary
This work reports the consequences of nutrient management strategy, an example from southwestern Europe focused mainly on P reduction. Upstream rivers reveal indices of recoveries following the significant diminution of P, while eutrophication continues to increase downstream, especially when N is the limiting factor. This long-term ecosystem-scale analysis provides more arguments for a dual-nutrient (N and P) management strategy to mitigate eutrophication along the freshwater–marine continuum.
