Zusammenfassung

Biosphere reserves have three main objectives: conserving biological and cultural diversity; providing models of land management and experimental sites for sustainable development, and serving as sites for research, environmental monitoring, education and training. These three biosphere reserve functions can be implemented only through involving and mobilizing all the structures and stakeholders concerned. Therefore, a biosphere reserve must have the necessary tools to help it reach its various objectives. Geographic Information Systems (GIS) are such tools, explicitly expressed to support management, monitoring and communication between the actors of the reserve. GIS are able to act as platform where relevant knowledge, information (e.g. case studies) and data on different issues can be shared, analysed, searched through databases, and managed, and where synthesized findings, lessons learned and best practices are made available. But, to become accepted as Biosphere reserve by the different stakeholders there is a long and intensive discussion to follow. Accompanying these processes of discussing the benefits of a new Biosphere reserve in the Bliesgau region (Saarland / Germany), within a students project, we developed a GIS – architecture as information platform using the iterative prototyping approach. This was done in close collaboration with the ministry of environment of the Saarland, which is driving the Bliesgau region towards a biosphere reserve. Based on a requirements analysis, a client-server architecture using open source components (Postgres/Postgis, GRASS, ZMapServer UMN, Zope CMS) was set up. Most important point in the development was the implementation of an Internet Map Service as a communication and information tool for the stakeholders participating in the discussion. Visualising maps in an interactive manner is a much more direct and powerful communication tool than displaying lists and tables. In addition, Web-based maps are able to give the different users the same level of information in a way easy to understand and easy to access.
