Implication

Review uncovers the ecological and economic impacts of freshwater browning across aquatic ecosystems, indicating that targeted landscape and land-use management offers viable local mitigation.

Key Points

Synthesize the drivers and ecosystem service impacts of freshwater browning and evaluate practical local land-management mitigation strategies.
Narrative review of ecological mechanisms, environmental drivers, and mitigation interventions across freshwater systems, with an emphasis on Scandinavia.
Qualitative synthesis of impacts on light penetration, aquatic food webs, and drinking water treatment associated with elevated organic carbon and iron.
Freshwater browning impairs vital ecosystem services by increasing drinking water purification costs and diminishing lake fish production through reduced light penetration.
The primary drivers include climate change, catchment recovery from historical acidification, and land-use shifts that mobilize dissolved organic carbon and iron into surface waters.
Targeted land-use management in hydrologically connected landscape zones represents the most feasible strategy to mitigate local freshwater browning.
