Cluster for Cloud to Coast Climate Change Adaptation (C5a)


The North Sea Region (NSR) is facing a significant increase in the frequency and severity of floods in response to climate change. Flood management approaches have to urgently adapt to this new reality to keep people safe, the environment healthy and our economies prosperous.

To respond to this challenge the project Cluster for Cloud to Coast Climate Change Adaptation (C5A) aims to deliver a from ‘Cloud-to-Coast’ (C2C) approach to the management of flood risk. C2C is an approach recognising that opportunities to build resilience to flooding starts from the moment the rain falls (Cloud) to flow through the rural catchment and the urban cities, before interacting with coastal storms (Coast).

The whole-of-system approach integrates four constituent systems (catchment, coasts, cities, infrastructure networks) and enables the development of multifunctional and adaptable solutions that deliver more sustainable, integrated and multifunctional solutions across the NSR.  The project builds upon the outcomes of seven ongoing Interreg NSR projects an seven case studies (located Denmark, Netherlands, Belgium, UK, Germany and Sweden) to ensure the approach is both evidence-based and practical.
