Defacto Urbanism

De zeespiegel stijgt mogelijk sneller dan verwacht. In opdracht van het Deltaprogramma, en de ministeries van BZK en I&W verkennen we de impact van versnelde zeespiegelstijging op andere ruimtelijk economische thema's zoals: verstedelijking, ecologie, energietrasitie, landbouw en mobiliteit.

The past few years have shown that the sea level in the course of the 21st century may rise faster than the prediction. A frequently asked question is: what does this mean for the Netherlands? Which functions will come under pressure and what opportunities does this bring? Those questions are being explored in our on-going project, “Accelerated Sea Level Rise”.

Our initial sketch for the Double D**e Project!

The sketch illustrates the characteristic of the Southwest Delta that is the landscape with parallel d**es, it is historically developed by stepped reclamation of the naturally extending flood plains. By re-opening the current primary sea d**e, the ebb and flow of the tide can enter the land behind it and deposit sediments. The second d**e is and can be lower than the primary d**e since the water force will already be reduced by the primary levee and the created foreshore.

Wissel Polder is released!

Transitional polders between double d**es capture valuable silt
The principle of a transitional polder is based on a double d**e. An opening is made in the current sea d**e, so that the ebb and flow of the tide once again have free play on the land behind it. The sea is then held back by a second d**e: an existing, former sea d**e or a new d**e to be constructed. This second d**e can be lower and less expensive than the current sea defence, because the water has already lost its worst force behind the first d**e.

The polder between these double d**es will then slowly rise because of the silt that each tide builds up. Along the Western Scheldt this will be about 3 to 5 centimeters per year. So, after half a century, the land between the d**es will be up to three metres higher. In the meantime, the growing land can be used for aquaculture and growing saline crops. Later on, the fertile sea clay can be used for regular agriculture once more. In addition, part of the alternating polder can be set up as a nature reserve for waders and other plant and animal species that depend on tidal areas.

The Water as Leverage for Resilient Cities Asia (WaL) programme is the winner of the Dutch Design Awards.

After the announcement of winning in the ‘Best Commissioning’ category, Henk Ovink, the Netherlands Special Envoy for International Water Affairs, expressed his gratitude and thanked the jury and the organisation.

Defacto Urbanism is proud to, together with CDR, RoyalHaskoningDHV, Nelen en Schuurmans, Devcon, WUR and the Khulna University, be one of the design teams participating in Water as Leverage. Water is at the core of the programme, the interconnecting element and a leverage for turning the biggest risk into the greatest opportunity. Using water as a starting point to work with it in an inclusive and integrated way leverages many other challenges societies face. Using Water as Leverage can induce an effect on social development and employment, sustainable economic development and the recovery of biodiversity. Commissioning these challenges and persuading multidisciplinary teams to look at these challenges from an integrated, design-driven and innovative perspective thrives action and enthusiasm on the ground.

Water around the world is not only the most important risk factor, but is the biggest all-encompassing challenge. Water has the potential for transformative and sustainable impact and a comprehensive cultural shift. This is the idea behind Water as Leverage, which contributes to the Paris Agreeme...

Our study from 2014,
the study shows the riverine flooding in Bangladesh and its impact to the urban area.
Regular flooding affects about fifth of the country annually, but have reached more serious proportions once every 10-15 years historically. Extreme flooding gravely disrupts normal life patterns and affects the physical, environmental, economic and quality of living.

Bangladesh is confronted with an increasing flood risk, water supply and quality challenges, increase of population and urban expansion. A coherent strategic long term vision is required to create sustainable future development of the country.
