Rivers and streams

Researcher Scientist, PhD

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.

I dette pilotprosjektet bruker vi folkeforskning for å samle inn viktig informasjon om landets elver og bekker.

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.

NIVA's sections on Freshwater Ecology 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.
