Deciphering the intricate link between watershed-level land use changes and reservoir eutrophication in central Argentina over the 20th-21st century

Key Points

• Eutrophication rates increased significantly, particularly as agricultural land expanded.
• The analysis identified a direct correlation between nutrient levels and land use changes over two centuries.
• Trend analysis utilized historical data from multiple reservoirs and surrounding land use patterns.
• Findings highlight the urgency for sustainable land management practices to mitigate eutrophication.
