The impact of open-pit lignite mining on water resources creates significant conflicts between different interest groups, such as the mining industry, water supply agencies, and agriculture in the mining region. The activities of each of the interest groups modify the water resources system and at the same time the conditions for resources use by other groups. Consequently, there is an apparent need for the analysis of regional water policies to reconcile the conflicting interests within such socio-eeonomic environmental systems. On that, a collaborative study between the International Institute for Applied Systems Analysis and Research Institutes in the German Democratic Republic (GDR) and Poland is directed.
