The long-term objective is to develop model tools for environmental effects such as acidification of soils and waters, eutrophication of terrestrial ecosystems and ozone effects to crops and forests. In addition, the tools should also be capable of handling possible climate changes in terms of increased temperatures and changed precipitation patterns. The priority of the work is studies of:

· Model tools describing dynamic effects of acid deposition on forest soils, surface water chemistry and fish survival.

· A coupled sulphur, nitrogen and coal model as a tool for describing dynamic effects of deposition and climate on forest growth and soil processes.

· The possibilities to develop an integrated model describing effects of chemistry, nitrogen, temperature, moisture and competitive aspects of ground vegetation biodiversity.
