Resilient Delta uses a holistic approach of the delta region as a complex system of interwoven sub-systems. The first Resilient Delta theme is therefore at a ~100×100 km scale and uses the Rotterdam delta region as showcase for other delta regions in the world. However, much can also be learned from zooming in on specific part of the delta system. Resilient Delta therefore focuses on two smaller-scale systems of the delta region, i.e. the City of Rotterdam (theme 2) and the Port of Rotterdam (theme 3).
Next to that, a system-approach goes hand in hand with methodological challenges, such as bringing very different disciplines together, collaborating with external (societal and economical) partners, or taking the citizens and inhabitants into a scientific co-creation process. Our 4th theme, Methodology, deals with these issues.
