Nitrogen, Water and Global Change – an Integrated Modeling Perspective

TNitrogen pollution is an important issue in many in aquatic systems. This paper discusses approaches to model nitrogen and water under global change.

Emphasis will be paid to integrated model systems that cover causes, effects and solutions of nitrogen pollution in different aquatic systems: rivers, lakes, groundwater and coastal seas. Attention will be paid to impacts of global change on future water quality and water quantity, and the availability of clean water for nature and society. Examples will be given of global and regional modelling studies on the causes of the problem and on possible future solutions.
