Risk management at transnational level is an important tool for setting up alternative risk scenarios within the Strategic Environmental Assessment framework (SEA). This is one result that was realised when implementing the CADSES project "ISOTEIA" which deals with an integrated system to assess Territorial and Environmental Impacts (TEIA) regarding resource management and regional planning. Moreover, it was discovered that there is a serious gap between the scientific state-of-the-art in the field of managing risks on the one hand, and on the other hand, the actual implementation of transnational approaches and mechanisms in risk management. STRiM will bridge this gap between science and ad-hoc solutions at transnational level and will develop new mechanisms for Strategic Environmental Assessment which is required by EU legislation. In the STRiM project partners from ten countries - EU member states and accession countries - will be involved. Main target groups of the project are stakeholders in risk management who need serious scientific backup when applying the "precautionary principle", which means measures will be proposed to reduce and prevent environmental risks and disasters. Expected Results: The main objective of STRiM is to establish a remotely and commonly accessible system for decision support concerning risk management at transnational level. After studying the existing national systems and the scientific state-of-the-art in risk management, the project will define a comprehensive service concerning transnational risk management. Specific outputs of the project will be: - Establishment of a new transnational network on risk management, - Promotion of transnational actions for preventing environmental damage, - Support of best-practice implementation in risk assessment, - Set-up of new, user-friendly mechanisms for environmental risk management, - Supply of stakeholders with dynamic decision support tools, - Construction of new knowledge bases for regional communities, comprising geo-databases, reports and management plans, - Provision of an infrastructure for training, - Development of demo GIS applications for training purposes.
