Perpignan Mediterranean metropolis - Prefiguring the adaptation strategy of the integrated management of the Catalan sandy coast to climate change

1 - Cerema's action

Cerema's study program includes 4 complementary missions:

• develop a diagnosis of the area by synthesizing the existing elements,

• identify the areas at risk areas by 2050,

• to build the basis of the local strategy (Littoral Sableux Catalan 2050),

• plan the implementation and/or spatial recompositions on 4 pilot sites.

2 - The expected results

The main actions of the study will be carried out in the form of study reports, cartographic analyses (current and projected), as well as collaborative workshops on perception and prospection. In particular, the following are planned :

• a report distributed to retro-coastal elected officials through dynamic and visual presentations,

• a mapping with key figures to launch the study and a "sketch" mapping to the proposed strategy.

This study will be highlighted through :

• the production of materials that can be distributed regionally and national level,

• the integration of the results in the dynamic mapping of ObsCat,

• communication on a national scale to to promote the initiative, continue the process and share feedback.

3 - Governance

The governance of the project will be based on two bodies: a steering committee and a technical committee. These bodies will associate :

• systematically PMMCU, Leucate, CCSR, CCACVI, DDTM Pyrénées orientales, DREAL and Occitanie Region, AURCA and Cerema,

• occasionally other stakeholders, such as partner communities such, PL21 governance and other stakeholders in relation to the themes and the needs defined by the technical committee.
