C5a: preparing for the potential effects of climate change

The Cluster for Cloud-to-Coast Climate Change Adaptation project (C5a) promotes the adoption of a whole system and long-term perspective to cope with the physical, economic and social consequences of future flooding.

In this project, we also factored in the effects of climate change, which is the major driver of weather extremes.

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 worsened by a confluence of autonomous developments beyond climate change, such as population growth, ageing infrastructure, economic growth, subsidence and social needs. 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 views on dealing with risks in the new reality. This requires a more integrated manner of thinking which will lead to actions and solutions that are future proof.

Cloud-to-Coast (C2C) approach

The C5a project has resulted in the development of 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 for Flood risk management in the North Sea region. To ensure that the approach is both evidence-based and practical, it builds on the outcomes of seven previous Interreg North Sea region projects.

More information on the Cloud2Coast approach, how it is applied in practice and a useful toolbox can be found on the Cloud 2 Coast website.

There is also information about the stakeholders and detailed information about the seven case studies done in Denmark, the Netherlands, UK, Germany, Belgium and Sweden. Each case study provides an example of the Cloud2Coast approach applied in real life contexts.
