The ASTA Programme
The objective of the Programme is to produce scientific knowledge, data and modelling tools in support of international measures to control transboundary air pollution in Europe and to develop national strategies and measures in various sectors that are affected by transboundary air pollution.

This means:

To strengthen and secure the future supply of Swedish expertise and scientific knowledge for the purposes of international negotiations on environmental agreements and national strategies,

to build a consensus on research findings through international networks,

to provide information about and visualise the regional air pollution problem in order to increase policymakers understanding of the issues and

to promote a better understanding of the interface between science and politics.

The Swedish ASTA programme carries out research on acidification of soil and water, the effects of nitrogen input on forest ecosystems, the effects of ground level ozone on vegetation and regional transport and concentrations of particulate air pollution. The first phase started in 1999, ASTA now continues with a secound phase 2003- 2006. The effects of increased extraction of forest biofuels are also studied in conjunction with the effects of acidification of soil and water and the effects of nitrogen input.

The Programme takes account of relevant international and national initiatives in the form of conventions, EC Directives and changes in strategies and approaches on the part of industry, public authorities and the general public.
