Presentation and objectives of the project
INSeaPTION addresses the urgent need to co-develop coastal climate services tailored to the needs and practices of coastal users. It will develop innovative methodologies that integrate sea-level projections, information on biophysical and socio-economic impacts, and adaptation options with decision-making and governance frameworks. Specifically, the project will co-design and co-develop the following coastal climate services with several groups of diverse users:
Global to regional coastal climate service (S.1, WP-1), addressing the needs of major companies, international organizations and governments to have globally consistent information on sea-level rise, its impacts and adaptation pathways for long-term locational planning, climate policy making and financing adaptation and loss & damages.
Regional to local coastal climate services addressing the needs of planners and policy makers for local tailored sea-level projections, impact and adaptation information useful for long-term development, infrastructure and land-use planning for two high impact territories: the Maldives (S.2, WP-2) and French Polynesia (S.3, WP-3).
LIENSs is mainly involved in WP 2 (Maldives) et WP 3 (French Polynesia). In WP2, LIENSs contributes to assessing climate change biophysical impacts. Additionally, LIENSs coordinates WP3, in close collaboration with BRGM and Créocéan (PhD thesis of Heitea TEROROTUA).

LIENSs will more specifically generate the following results:
Work Package 2 - Assessment of multi-decadal island and shoreline change in the inhabited islands of the Maldives
- Assessment of changes in island land area and shoreline position
- Determination of the drivers of island and shoreline change
> Results relating to this task are provided in the following paper: Duvat V.K.E., Magnan A.K., 2019. Rapid human-driven undermining of atoll island capacity to adjust to ocean climate-related pressures. Nature Scientific Reports, 9, 15129.
Work Package 3 - French Polynesia
1.Co-building of tailored coastal climate services
- Coastal climate service Risk of physical destabilisation of beaches and atoll islands (coastal erosion issue)
- Coastal climate service Adaptation pathways in atolls (link with the STORISK project)
- Coastal climate service Nature-based solutions (investigation of the role of the indigenous vegetation in island and shoreline stabilization)
> These Coastal climate services are currently being designed.
2. Assessment of adaptation to climate change in French Polynesia (link with the STORISK project)
- Development of a methodology of evaluation of the adaptation to the climate change on a specific territory
> This task has been realised with the support of Toanui VIRIAMU (research assistant) in 2019 (paper in prep.)
