ZOOM: What is SafN ?

To find out all about Nature-based Adaptation Solutions, here is a review of the conference held on November 25 in La Garde.

Nature-based solutions (NBS) refer to "actions aimed at preserving, sustainably managing and restoring ecosystem functionality to directly address societal challenges in an efficient and adaptive manner while ensuring human well-being and biodiversity benefits" (International Union for Conservation of Nature). Some of them target more specifically the issue of adaptation to climate change: Nature-based adaptation solutions (SafN) which were widely highlighted at the World Conservation Congress in Marseille. However, many obstacles have already been identified that complicate their appropriation and practical implementation by local stakeholders (local authorities, developers, farmers, foresters, etc.).

This symposium sought to provide answers to the following questions:

How to identify a SafN? Which actors should be mobilized and at what scale(s) should they be designed?

How to monitor and evaluate their costs and effectiveness? What funding should be used? How should they be linked to planning documents?

After an introduction by Ronan Dantec (senator, vice-president of the Commission on Land Use Planning and Sustainable Development) on the link between the climate and biodiversity crises, and also on the question of financing SafN, Solène Cusset (OFB) and Aurélie Tailleur (ADEME) took part in an exercise to define SafN. This was illustrated by two case studies. The first, on the Jarret/La Rose NPNRU project, was described by Nadine Florence (Métropole AMP, Gemapi department) and Thiphaine Gourlay (Syndicat Mixte de l'Huveaune), and highlighted the challenges of desoiling and combating heat islands in a multi-stressed urban environment. The second, led by Patrick Pequignot (Var Department), was an opportunity to visit the Plan de la Garde Nature Park, designed to reduce the risk of flooding while improving the living environment of the inhabitants.

During the afternoon, two round tables were organized:

- One on the economic aspect and the question of the deployment of SafN on a larger scale;

- The other on the need to integrate them as far upstream as possible in projects, particularly in the planning phase.

This conference is part of the continuation of a partnership between ADEME, Cerema, and the SUD Region for the past three years, on strategies for adaptation to climate change. The 2021 edition was organized in partnership with the French Office of Biodiversity in the framework of the Life ARTISAN project.
