Development of Design Principles

If the most important climate variables and the expected changes are known, design principles can be developed. These principles are dependent on the specific context of the region and can be applied on national, regional or local levels. The following design principles can be developed for the Netherlands:

• Build mainly at higher altitudes in the landscape, use waterproof and innovative solutions in lower areas;

• Create a new coastal defence in front of the existing one;

• Create a robust ecological structure in the lower areas of the Netherlands, which stay wet during dry periods;

• Inundate periodically in lower areas if necessary;

• Protect the valuable economic and cultural-historical places, also in the lowest parts of the country;

• Create water buffers in order to keep fresh and clean water available in dry periods for drinking water and agricultural purposes;

• Use water as a steering principle in spatial planning.

In Fig. 2.11 these principles are used to design an image of a future climate adaptive Netherlands [Roggema, 2007a].
