Coordinated by BRGM and co-financed by the programme Horizon 2020, the European project CoCliCo offered an open, free-access online service to support decision-making on coastal risks against a backdrop of climate change.

Challenges and needs

Rising sea levels, increasingly intense storms, changing coastlines: the impacts of climate change are no longer distant threats and are already reshaping Europe's coastal regions.

By 2050, between 600,000 and 1.75 million people living in Europe's coastal zones will be faced with rising sea levels, coastal flooding and the corresponding economic disruption. The question is no longer whether we should act, but how quickly we can scale up solutions.

With this in mind, BRGM coordinated the European CoCliCo project from 2021 to 2025.

Results

The CoCliCo project developed an open-source web platform providing users with information on current and future coastal risks, with the aim of improving decision-making for coastal risk management and adaptation, by setting up a central integrated service dedicated to coastal adaptation and the rise in sea-level.

Aimed at public authorities, urban planners, infrastructure managers and researchers, CoCliCo provides high-resolution projections of sea-level rise, flood hazard assessments, risk exposure analyses and cost-benefit comparisons of different adaptation strategies. All this is presented in an intuitive cartographic interface, based on open and reliable data sets.

CoCliCo enables you to:

  • explore future scenarios  of coastal risks,
  • assess the vulnerability of populations and infrastructures,
  • compare adaptation options using cost-benefit analyses,
  • visualise impacts and solutions via predefined use cases,
  • use our models for your own calculations via the workspace and download data from our STAC catalogue.

A strategic memorandum for European decision-makers

As part of the CoCliCo project, and with the support of the European projects ProtectScore and Rest-Coast, a strategic memorandum has been published. It underlines the urgency of coastal risks and presents key messages for European decision-makers on how to anticipate them more effectively.

Coastal zones require major transformations

Europe's coastal zones have reached a critical point under the combined effect of climate change and the urbanisation. In many regions, the limits of current adaptation strategies have already been exceeded, calling for a reassessment of conventional coastal management practices. The scientific evidence has been clear for decades: inaction is no longer an option.

A European climate service dedicated to coastal zones: a key condition for successful adaptation

The CoCliCo project has demonstrated that a Europe-wide basic climate service dedicated to coastal adaptation is both feasible and ready for deployment. Climate services play a crucial role in the effective adaptation of coastal zones by providing public authorities, businesses and citizens with the knowledge they need to make informed decisions. However, other conditions are also essential: robust governance, adequate funding and public dialogue based on the principles of equity and justice.

Role of BRGM and its partners

To meet the challenge of developing this platform, BRGM, as project leader, brought together European organisations and researchers with proven track records in assessing coastal risks, the impact of rising sea levels and appropriate adaptations, as well as in research and cutting-edge technologies for the management of interoperable-geospatial-data management, science-based decision making and risk communication.

BRGM draws on its experience with the implementation of geospatial information management infrastructures for the assessment of coastal erosion and flooding hazards against a backdrop of rising sea level, and for risk assessment.

The aim is now to prolong the CoCliCo platform as part of the Copernicus Marine Service, through the contribution of its partner Mercator Ocean, while maintaining the open character of the platform, which allows project partners and third parties to use it for local needs.
