Natural Acidification Only

The environmental objective "Natural Acidification Only" is set to protect human health and ecosystems from acid deposition. The deposition of acidifying substances should not exceed critical loads and forestry practices will be adapted to avoid negative impacts on land and water.

How does CLEO research support the environmental objective Natural Acidification Only?
CLEO will develop modelling tools for predictions of climate change influence on acidification and eutrophication focusing on the leaching of nitrogen and acidifying compounds from forest soils to surface waters. Field data from empirical research and water monitoring programs are combined with a set of models covering different parts of the soil — water ecosystems to develop applicable tools for future predictions of acidification and eutrophication of surface waters.

The research includes an evaluation of existing data using statistical models (Project 2.1, Cluster 2) as well as testing and evaluation of different biogeochemical models on monitoring and experimental field data (Project 2.2, Cluster 2). CLEO will develop model systems consisting of different combinations of process models, catchment models and large scale hydrological models (Project 3.3, Cluster 3) to be able to provide predictions of acidification and eutrophication of surface waters on different geographical scales and for different scenarios (Projects 3.2, 3.4, Cluster 3). The various modelling activities will also employ scenarios for climate, pollutant deposition and land use (Project 1.3, Cluster 1).
