A recent Nature article with two NIVA co-authors shows that biodiversity in European streams and rivers has increased since the 1970s, but that the positive trend has stopped in the last decade.

OPINION: Near half of the global plastic leakage from land to sea comes from a few countries in Southeast Asia. To overcome the plastic problem, we need to treat the cause and not just the symptoms. We must turn the spotlight on the sources.

How are northern ecosystems affected by climate change, and how do different ecosystems affect each other? This 5-year Fram Centre research program aims to provide critical new knowledge related to: (1) Cross-ecosystem climate change impacts; and (2) How to best integrate cross-ecosystem linkages into cohesive management approaches.

The programme collects monitoring data from approximately 20 countries in Europe and North America to monitor and investigate the extent to which air pollution affects lakes and rivers, particularly regarding acidification, heavy metals and pollutants.

MadMacs (mass development of aquatic macrophytes; causes and consequences of macrophyte removal for ecosystem structure, function, and services) aims to determine the causes of mass development of water plants, and to study the direct and indirect consequences of their removal on ecosystem functions and services.

NIVA's sections on Freshwater Ecology and Nature-based Solutions have expertise in the monitoring and restoration of freshwater ecosystems and their biodiversity. We develop knowledge and understanding that provide a basis for applied, evidence-based freshwater management.
