French SHF meeting on climate change adaptation

The INSeaPTION project was represented at the SHF Meetings:

"Coastline and climate change - Adaptation of coasts, ports and estuaries to climate change"

on 21 and 22 November 2019 in Marne-la-Vallée (France).

 

The presentation focused on the “Impacts of chronic flooding, considering sea-level rise, on the critical infrastructures (airports, harbours…) of French Polynesia Polynesia”. This work was carried out within the framework of the co-construction of the Coastal Climate Service n°1 (CCS1) set up in French Polynesia for the INSeapTION project.

One of the consequences of SLR is the possibility of recurrent chronic flooding (or “nuisance flooding"), occurring at high tide, under calm weather conditions. This is likely to disrupt economic activities depending on harbour, airport, industrial or commercial infrastructures located in low-lying areas. French Polynesia is the perfect example, considering that many major harbour or airport infrastructures are located at very low elevation above sea level.

This co-developed CCS1 is part of a participatory approach and is based on available reference data (e.g. high-resolution lIdar data, tide levels and vertical reference frames, etc.) and considers specific local case studies (airports, harbor docks, international and commercial trade terminals...).  It includes not only the communication of regionalized SLR data in French Polynesia (values ​​and timelines), but also the definition of critical SLR thresholds at different time scales, with users. This could help in determine the specifications to be applied in infrastructure design studies (lowest-highest elevations required, most sensitive areas, choice of technical engineering solutions, renewal of airport operating concession, with a current term of 30 years). CCS1 also highlights critical deadlines for maintaining high levels of protection against chronic flooding, and revealed needs that were not previously formalized. The interest of this CCS1 is based on the fact that he critical infrastructures technical operators/managers have helped the project team to identify information tailored to specific needs that can be mobilized within an operational framework.

Institutional actors have a crucial role in adaptation to climate change, especially for highly vulnerable territories such as small tropical islands.

 

Here, we emphasize their major role in the co-design of tailored coastal climate services (CCS) based on a case study of French Polynesia. In this perspective, we assessed climate change perceptions by public authorities and identified their needs with regard to climate-related science. This assessment included an analysis of the decision-making context, semi-structured interviews with practitioners representing 23 administrative divisions directly or indirectly involved in climate change issues, and a workshop dedicated to discussing needs in terms of CCS.

 

Generally, respondents did not identify climate change as a major current issue in French Polynesia; they showed more concern for economic growth, pollution, land tenure, and land use planning. However, interviewees were concerned about future impacts of sea-level rise (SLR) and ocean warming and acidification, mentioning in particular their detrimental impacts on marine ecosystems, shoreline position, economy (especially agriculture and the blue economy), and freshwater resources. The interviewed practitioners showed particular interest in SLR projections for future decades up to a century, and for knowledge on expected impacts to critical infrastructure, coastal systems, and natural resources.

 

Practitioners’ needs made it possible to co-define four CCS to be developed:

(1) the design of sea-level-rise compatible critical infrastructures (airports and ports);

(2) adapting to the risk of destabilization of beaches and reef islands;

(3) professional training on climate change impacts and adaptation, including an analysis of potentially emerging new jobs in the SLR context;

(4) the development of participatory approaches for observing climate change impacts.

 

While the co-development of these CCS will require a multiyear engagement of stakeholders concerned with climate change adaptation, our results already shed light on specific needs for salient CCS in highly vulnerable tropical island territories.

Web map of sea-level projections

In response to the demand for easier access to sea-level projections, a web mapping tool has been produced within the ERA4CS INSeaPTION and ECLISEA projects: 

https://sealevelrise.brgm.fr/

The tool allow users to vizualize and download projections of sea-level rise over the 21st century, including projections of the 5th assessment report of the IPCC (Internal Panel on Climate Change) and low end projections (https://www.mdpi.com/2073-4441/11/7/1507). It also includes interactive features allowing to produce user-defined scenarios based on assumptions on glaciers, ice-sheets, etc. The tool will be extended to include high-end projections as well as those from the Special Report of Ocean and Cryosphere (SROCC). 

The tool has been produced by our colleagues Robin Quique, Rémi Thiéblemont and Agnès Tellez-Arenas, with support from sea-level scientists from the INSeaPTION and ECLISEA projects, as well as from the WCRP Sea-Level Grand Challenge. It uses data made available by the Integrated Data Center at the University of Hamburg in Germany (available as NetCDF datasets at https://icdc.cen.uni-hamburg.de/1/daten/ocean/ar5-slr.html). We are grateful to colleagues who shared their expertise to make this tool publicly available, especially colleaguies from the Universities of Hamburg, Utrecht and NIOZ. 

 

Synthesis of the September 2018 first Workshop on Global Climate Services in Haarlem is now available

The INSeaPTION global user workshop on climate services was organized on September 25th and 26th in Haarlem, Netherlands.

 

This report documents the outcomes of the first workshop on global coastal climate services of the INSeaPTION project held in autumn 2018. The workshop brought together 22 coastal experts and stakeholders from both the public and private sectors working within a range of different country contexts in order to identify a set of user needs that can potentially be translated into coastal climate services by the INSeaPTION project over the course of the next 2 years of project life.



To quickly synthesize this workshop on 25-26 September 2018:

  • Key climate services were identified along 3 different types:
  • Regarding decision-problems, in particular, long-term decisions, e.g. for siting and taking adaptation measures regarding critical infrastructure such as nuclear power plants, was found to be of great interest.
  • Regarding methods and tools, developing a methodology for attributing climate change and sea-level rise to coastal risk and adaptation was found to be of high interest in the context of current discussions on adaptation finance.
  • Regarding methodological guidance, support for developing SLR information to support in local decisions, particularly in developing country contexts, where data availability presents a significant challenge, was seen as a climate service of potentially high interest to be addressed within the project.
  • A reflection emerging out of the workshop is that further work should be undertaken to enrol decision-makers with a more global perspective on coastal adaptation, such as, adaptation finance actors under the UNFCCC or development finance decision-makers more broadly.
  • A key step in the next phase of the project will be to more narrowly define the set of key users and climate services, given the initial input of this first workshop.

Co-design of four coastal climate services is beginning in French Polynesia

During the first workshop in French Polynesia, coastal climate services (CCS) proposals were co-designed with the workshop participants based on the main challenges highlighted by the stakeholders.

Heitea TEROROTUA, PhD student contributing to the development of coastal climate services in French Polynesia, is currently between Tahiti and Rangiroa until the end of February 2019. Her main objectives are to work with all the stakeholders in order to develop further the following four coastal climate services :

  • CCS 1 : Critical infrastructures and sea-level rise
  • CCS 2 : Destabilisation of high and low islands and adaptation strategies
  • CCS 3 : Professional training and new jobs
  • CCS 4 : Participatory science to support the observation of impacts

To this end, several meetings and workshops will be planned with the involved stakeholders. On February 2019, Aurélie Maspataud (BRGM) and Virginie Duvat (LIENSs) will join Heitea on Tahiti for the workshops that will be held in Tahiti.

Third INSeaPTION User Workshop: adressing the global case study

The third INSeaPTION User Workshop was held in Haarlem, The Netherlands, on Sept 25-26, 2018. The workshop provides a basis to identify key user needs of global users and potential scientific methods that INSeaPTION can develop and apply to address these needs. Global users refer to organisations with global concerns such as international organisations supporting development and adaptation, as well as to users whose activity is distributed in many places worldwide, so that the same type of sea level and impact and information is needed in many places.

 

22 participants from different organisations participated to the workshop. présentations from international organisations (OECD), coastal consulting or reinsurance companies (Royal Haskonning, Deltares, Munich Re), energy supply industry (Electricité de France) presented their views on future potential coastal climate services supporting their activies. Then, break-out groups further discussed needs of sea level and coastal impacts information to support adaptation of critical infrastructures (e.g. Thames River Estuary). The workshop was openened and concluded by Robert Nicholls, scientific Advisor of the INSeaPTION project. Three INSeaPTION project partners were involved in the organisation of this event: IMAU (Erwin Lambert and Roderik Van De Wal), GCF (Sandy Bisaro), and BRGM (Gonéri Le Cozannet).

Second User Workshop in French Polynesia

INSeaPTION starts with analysing and understanding the user needs in terms of coastal climate services using sea level projections. Since early March 2018, a number of meeting have been organised by the INSeaPTION project partners in French Polynesia, namely CREOCEAN, the University of La Rochelle and BRGM. These meetings included:  
  • Individual interviews with stakeholders from 28 February to 31st March, by Heitea Terorotua (PhD student at CREOCEAN in charge of the social science surveys in Polynesia).
  • Official meetings, from 13th to 23rd April, including the Government of French Polynesia, the High Commission of the French Republic, the Assembly of French Polynesia as well as other public and private stakeholders concerned with sea level rise and its impacts in Tahiti and Rangiroa, an atoll island in the Tuamotu archipelago
  • A workshop on coastal climate services organised from 22 to 23rd March at the Art Conservatory in Papeete (Tahiti).

These two days gathered about 50 participants and included presentations, roudtables and discussions with stakeholders. They helped identifying specific needs for coastal climate services and their potential use in decision making in French Polynesia. This includes scientific information to assess regional indicator in relation to the sustainable development goals, dedicated services for critical infrastructures, beaches and low island habitability as well as needs for mutual exchanges of knowlege, professional training and sharing feedbacks on various coastal adaptation practices.

These workshops and consultation have been made possible owing to the dedication of our partners in Polynesia, especially the CREOCEAN and BRGM offices in Tahiti (Esther Mercier, Julien Guillet and Pauline Corbier) as well as volunteers who helped preparing the room and welcoming attendees in the Polynesian way. We thank Esther, Jonathan, Anais, Heremoana, Vai and Arii for their support to this event.

First user workshop

INSeaPTION News First User Workshop Maldives

First user workshop in the Maldives 11.02.18 – 17.02.18

 

During the first user workshop of INSeaPTION in the Maldives, the team has met with multiple stakeholders from the national government, local communities, academia and oceanographers, to start the process of co-developing coastal climate services for the Maldives.

In close cooperation with the Climate Change Department of the Ministry for Environment and Energy, user needs and current practices in coastal protection and adaptation have been discussed. Close attention was paid to identify the needs of policy-makers and coastal planners regarding coastal flood and erosion risk. Here, current decision-making processes and governance frameworks were discussed and the necessity to incorporate sea-level rise projections and information on biophysical impacts was highlighted. Already, concrete user-needs have crystallized.

First, the need for science based decision-making criteria for the allocation of resources for coastal adaptation was emphasized. As of now sea-level rise projections and shoreline dynamics have not been fully integrated in this decision-making process.

Second, users in the Maldives underlined the need to include sea-level rise projections in risk assessments for individual islands. Here, they are facing the challenge to distinguish between risk attributable to sea-level rise and other processes. This is especially important in the context of current discussions on international adaptation finance.

Additionally, the team has initiated discussions to share knowledge and build capacity in the course of the project. Here, especially first-hand experiences during a visit to the island of Fulidhoo in Vaavu Atoll were fruitful. Seeing the problems local communities face again underscored the urgent need for co-developing coastal climate services tailored to the need of decision-makers and local planners.

The first workshop thus gives an important input in the next phase of work in the INSeaPTION project. The project team is looking forward to developing the scientific work based on the identified needs of the Maldivian users. The team would like to sincerely thank the Maldivian Users for their time, commitment and hospitality. We anticipate a fruitful and rewarding collaboration in this exiting and unique project. Baraabaru!

First INseaPTION kick-off meeting

The kick-off meeting of the INSeaPTION project has taken place in Paris, on 8-10 November 2017

 

The project partners have officially launched the INSeaPTION project in Paris on 8 to 10 November 2018. The starting point of the discussion was the analysis of the decision context of adaptation practitioners, as well as the practical organization of the co-design of coastal climate services in the 3 case studies (Global, Maldives and French Polynesia). Furthermore, the participant shared knowledge regarding sea level rise, extreme water levels and wave, shoreline changes and coastal risks as well as the social and economic dimension of adaptation. The meeting gathered 18 scientists and engineers from the Global Climate Forum (Germany), CREOCEAN (France), the Universities of La Rochelle (France), Utrecht (The Netherlands), of Balearic Islands (Spain) as well as BRGM. The next milestone of the project will be a first set of stakeholders workshops in the two regional case studies (Maldives and French Polynesia). These workshops are scheduled in February and March 2018.

We thank all the participants to this meeting and those who could not attend for their commitment in the preparation of these workshops.
