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.

In this pilot project, we're using citizen science to gather important information about Norwegian rivers and streams.

ENCORE is led by Karel Viaene at ARCHE Consulting. The objective of ENCORE is to develop a probabilistic modelling framework for estimation of environmental risk of chemical mixtures in watersheds across Europe.

We need to improve our understanding of the occurrence of antimicrobial resistance (AMR) in surface waters, particularly downstream of urban waste water treatment plants. However, at present there is no European overview of the presence of AMR in surface waters. This project will develop a basic approach and methodology for a European scale AMR monitoring of surface waters.

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.
