Assessing the environmental and social co-benefits and disbenefits of natural risk management measures.

Risk management measures (RMM) participate in the sustainability of cities and communities through the protection of these socio-eco-environmental systems against threatening events, and by ensuring system recovery. They include structural measures that are grey or green/blue solutions, or hybrid solutions combining the two former types. These measures can provide environmental and social co-benefits (e.

Watershed and river managers often face difficult choices between safety issues related to floods and degraded hydraulic structures, requiring urgent works and involving environmental stakes such as biodiversity, landscapes and rare species. These choices require taking precise ecological data and existing knowledge into account. Unfortunately, such databases and pre-existing knowledge are rarely available or they are only fragmentary and exist at the local scale for parts of areas classified as protected, or they are limited to a few species.
