AR2U086 R&D Studio – Spatial Strategies for the Global Metropolis

2023-04-21

Excessive carbon emission has led to global warming, resulting in climate change. Due to this, the natural carbon and water cycles are disbalanced leading to extreme (water-related) events, such as flooding, periods of drought and diminished water quality. The degradation of ecosystems and threat to human survival are direct consequences of this process.


There is an urgency to act in the upcoming seven years to remain below the 1,5 degree global temperature rise. Aside from reducing CO2 emissions in long-term processes, carbon capturing is crucial to achieve short-term ambitions. Therefore, this study investigates the implementation of (nature-based) carbon sinks strategies, using water(bodies) as a tool, in North-West Europe..

This report fills the gap of knowledge on how to implement water-based decarbonization through spatial interventions in North-West Europe.
Firstly, the technical aspects of water-based decarbonization are studied by reviewing existing literature, providing the required spatial conditions for the implementation of water-related carbon sinks. The historical and current conditions in North-West Europe are mapped and analysed. Comparing these results, an evidence-based selection of feasible intervention areas are determined.


Our analysis shows that the EuroDelta is the strategic location for the spatial vision for North-West Europe. There is a need for a paradigm shift to restore the self-sustaining system of the Delta, demanding Nature Based Solutions. Wetland restoration is the most efficient, low cost approach of climate change mitigation as the free, well-functioning services of these carbon sinks naturally make way for long-term restoration of the natural balance and societal well-being. They should be restored in original historical sites and the Dutch Delta is suitable. Therefore bottom-up approaches are required in global visions as wetlands restoration is context-specific.

We conclude that de Krimpenerwaard polder and the Port of Rotterdam are effective, feasible, and inclusive solutions to tackle both climate change and societal challenges while providing long-term water-resilience and livability through all scales. Agricultural sectors will shift to sustainable farming and (port-)industries are held accountable for their emission. A limitation is the disregard on the emission of methane which in further research should be taken into account.
