9 IRONCURTAIN EU5 FRAMEWORK PJOJECT Within the fifth framework programme part "Quality of life and management of living resources" the project relates to key action 5 "Sustainable agriculture, fisheries and forestry and integrated development of rural areas including mountain areas". It especially addresses key area 5.5 "New tools and models for the integrated and sustainable development of rural and other relevant areas". Therefore the overall goal of the project is to develop a methodology based on the manifold experience of the project partners leading to standardized tools and procedures for integrated resource evaluation, analysis and management following the principles of sustainable development. This will be tested and scaled in several case studies along an European north/south traverse. A generic model will be deduced to be successfully transferred and used in other relevant former iron curtain regions. Relevant users are represented mainly in institutions for regional and EU agricultural policy making, regional planning and resource (environmental) management.
