A sectoral flood safety approach has been the critical condition for Delta Urbanization in the Netherlands until now. But does this have to be the case for future urbanization as well? In the Dutch approach to flood safety, a dilemma appears to exist between (sectoral) flood safety on the one hand and biodiversity and flood resilience on the other. Where pursuit of flood safety, especially in a context of extreme climate scenario’s, might continue at the cost of biodiversity and resilience.

The thesis is on the reconciliation of the anthropogenic and natural systems of the Dutch Delta. It proposes a re-positioning of the relationship between peopel and nature. The concept and understanding of landscape identity is an expression of this relationship. In the case of the Dutch delta, landscape and flood safety are inevitably intertwined, and a certain relationship of human mastery over nature becomes apparent of this intertwining. The Dutch landscape is historically shaped through hydrology, geology, air and climate, however, contemporary landscapes represent severe anthropogenic intervening, enclosing and directing the dynamics of hydrology, geology, air and climate.
This thesis aims to understand the relationship between people and nature, through landscape Identity, the mutual relationship between people and landscape, shaped by and shaping landscape characteristics and individual and collective identity. Subsequently, proposing and testing a method for altering this relationship, based on the following hypothesis: Shifting the technocratic understanding of flood safety to align [again] with the trajectories of hydrology, geology, air and climate, which are both fundamentally shaping the landscape, allows the transition towards a biodiverse and flood resilient delta. Rethinking the relationship between people and nature, through landscape, is therefore essential. The concept of Building with Nature is tested as an approach to align the understanding of flood safety with the dynamics of air, water and soil. Proposing this re-alignment as the new critical condition for delta urbanization in transition towards a biodiverse and resilient delta. Ultimately, proving this apparent dilemma between flood safety on the one hand and biodiversity and resilience on the other, to be void.
