A newly released Nature paper with several NIVA co-authors highlights a continued management need for reduction of nutrient stress in lakes. It also shows that river management requires more complicated approaches to tackle several stressors simultaneously.

A vast number of new wastewater treatment plants in developing countries has led to an imbalance between phosphorous and nitrogen in surface waters. The result could be excessive growth of potentially poisonous algae with a preference for nitrogen. A new study calls for better nutrient reduction in order to maintain ecosystem biodiversity.

FuNitr will yield new knowledge and tools directly applicable to the safe realisation of CO2 capture technology, and thereby supporting the Norwegian Longship project for CO2 capture and storage. 

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.

The section for catchment biogeochemistry works to understand how various pollutants are spread in the environment and how they affect the water quality in rivers, lakes, and fjords. Our studies lay the foundation for and support political guidelines and improvements to reduce unwanted environmental impacts.
