The Norwegian Institute for Water Research (NIVA) is an independent institute, and Norway’s premier research community in a series of topics related to water. NIVA’s main tasks besides research are environmental monitoring, assessment, consultancy, and problem solving for decision makers in both the public and private sectors. We work locally, regionally, nationally, and internationally. We are experts on ecosystems in both freshwater and marine environments, from mountains, via lakes and rivers, to fjords, coasts and oceans.
