Une conférence intitulée « Blue nature-based solutions : why we go blue/grey instead of blue/green ? » aura lieu le vendredi 22 mars à 11h30 en ligne. Elle sera animée en anglais par Aude Zingraff-Hamed.
Résumé : In Europe, river planning and management took a decisive turn in the late 19th and early 20th centuries with the ratification of the EU’s Water Framework Directive (WFD). The WFD orchestrates restoration efforts and demands that all water bodies achieve a good ecological status (or potential). Along with the implementation of the WFD, the concept of nature-based solutions (NBS) to mitigate hydro-meteorological risk has also grown in popularity, especially in the context of change of climate patterns observed in the context of global climate changes. While NBS, such as river restoration, have been recognized as essential for the reestablishment of the socio-ecological functions of rivers and are presented as “the no-regret solution” to all our problems, their implementation is facing many limitations. Especially at the level of the decision-making process is the missing trust in the solutions a major bottleneck to their implementation. Also, engineers are not confident in designing the all-in-one solution. In this plenary talk, the facts and the beliefs around the NBS so as the role of the scientist in removing the non-rational barriers to NBS implementation will be intensively presented and discussed.
