C5a: preparing for the potential effects of climate change

The Cluster for Cloud-to-Coast Climate Change Adaptation project (C5a) aims to effect an efficient, and effective, adaptation to the physical, economic and social consequences of future flooding.

Within this project we also factor in the effects of climate change, which also contributes to the possibilities of future floodings.

Complexity of the issue

In the North Sea Region, the frequency and severity of floods and droughts continues to increase as a result of climate change. The complexity of the problems is exacerbated by a confluence of autonomous developments beyond climate change, such as population growth, ageing infrastructure, economic growth, subsidence, social needs, etcetera. A sectoral approach is therefore no longer adequate. This complexity of the issue at hand also makes the situation less predictable. In order to keep our populations safe, the environment healthy and our economies prosperous we need to adapt our view and how we deal with these risks to the new reality. This requires a more integrated structure of thinking and actions and solutions that can be adopted in the future.

Cloud-to-Coast (C2C) approach

In response, the C5a project will deliver a 'Cloud-to-Coast' (C2C) approach, integrating four constituent systems (catchment, coasts, cities, infrastructure networks) and enabling the development of multifunctional and adaptable solutions that deliver more sustainable, integrated and multifunctional solutions across the region. To ensure the approach is both evidence-based and practical, outcomes of seven ongoing Interreg NSR will be built upon.
