Declaration of the 3rd International Symposium on Flood Defence (ISFD3) 25-27 May 2005, Nijmegen, The Netherlands

摘要

1. That the increasing occupation and urbanization of floodprone areas results in an ongoing rise of investments, assets and vulnerability to flooding (underground infrastructure!), causing a destabilizing growth of economic damage due to floods; 2. the catastrophic effect floods may have on victims and countries' economies, especially in developing countries, where it hinders poverty reduction; 3. that countries implement structural and non-structural measures to prevent themselves against flooding, more and more on a catchment based approach, and that important results have been achieved in terms of casualty reduction; 4. that floods remain unavoidable natural hazards, probably aggravated in frequency and magnitude by climate change, and that protection is feasible only up to a reasonable level.
