Zusammenfassung
The management of natural resources and political and socio-economic subsystems requires complex simulation models supporting decision making procedures. Such models cover not only natural processes on different time horizons and spatial scales but also societal, industrial and agricultural developments as well as sociological constraints. Different structural dynamic models had to be combined to support multi-objective environmental decision problems. Because of the great variety and complexity of natural and anthropogenic processes considered for water management such an approach does not cover all the dynamic process extensions. For this reason, and to make different subsystems comparable, meta-models have to be developed. The questions that must be answered for water management options are how much water is available, for what purposes it will be used, who are the actors and stakeholders, and what kind of consequences follow from distinguished management options for the public, agriculture and industry, and what kind of environmental (or ecological) responses result from anthropogenic activities. In the paper, a meta-model approach will be propagated as a tool for a holistic management of environmental processes. Especially, the use of ecosystem services will be described and discussed as a base for environmental decision making.
