Two examples of redesigning port areas for VIETNAM a climate resilient future

Delta Cities are most often port cities. So is Rotterdam. Building preventing-layer, Westpoort provides spatial opportunities in the adaptive Between those elevated areas the natural water system is remained. This on the Rotterdam experience in climate change adaptation, the layout of the area as well as the development of a comprehensive disaster natural water system adds an import blue green structure to this mainly Rotterdam Centre for Resilient Delta Cities (RDC) was founded. The recovery plan. industrial development. This area is highly important: aim is to join forces in acceleration of the transition process to safe • for water storage and adaptive delta cities worldwide. RDC is a public private network CASE STUDY #2: NAH BE ( HO CHI MIN CITY VIETNAM) • to supply room for the river organization from leading companies, knowledge institutions, • for reduction of heat stress design firms and the municipality of Rotterdam. From the portfolio Challenge • to improve natural ventilation of RDC-members we share two examples of an integral approach in Ho Chi Minh City moves its main harbour activities from the old • for the development of adaptive buildings assessing and redesigning port areas with local partners to prepare to areas downstream the Sai Gon river. The VCAPS consortium examined the these ports and cities for a climate resilient future. Learn more possibilities to develop such a new port area near Na Beh. This development results in ‘stained glass’, in a ‘glass fitted in lead’. The about RDC and the possibilities for knowledge exchange at: Here an integrated proposal is needed to combine the development of ‘lead’ is formed by the green-blue structures, the ‘glass’ by the industrial www.rdcrotterdam.com harbour industry and residential area with main issues as water safety and and harbour activities. the availability of fresh water. CASE STUDY #1: CLIMATE STRESS TEST WESTPOORT AMSTERDAM CONCLUSION: WHAT CAN WE LEARN? Westpoort is the major part of the port area of Amsterdam. The port area Port activities ask for deep waters. But the deeper the water, the further Creating multibeneficial solutions by an integral approach includes the Sloter dikes and contains a lot of infrastructure and functions, the salt influence will reach, threatening the fresh water supply. Smart The cases of Westpoort and Nah Be show the possibilities of an integral which are of great importance to the Amsterdam metropolitan region. dredging reduces salinization. Therefore we introduce the principle of approach of combining spatial development in port areas in combination Westpoort is protected against coastal floods by the seawall at IJmuiden, ‘stepped dredging’. We dredge to different depths and create under water with climate change adaptation. Both examples show that next to water and against river floods by the levees along the Lek River and the IJssel steps. Salt water is heavier and will stay at the bottom of the river. and flooding, heat stress, drought and salinization can be also serious Lake. Through chain effects, the possible flooding of Westpoort causes Therefore salinization of the river to upstream areas will reduce. stressors for a climate resilient port city. damage and disruption that will be felt throughout the region. Solution By making a clear analysis with local and regional partners and bringing Challenge In the proposal shown the residential area is protected against flooding by in knowledge from engineering, ecology and (landscape) design together The Adaptation Programme Water Adaptive Westpoort is a joint initiative a ring dike, also the main road to the harbour. A tsunami shelter on the ring it is possible to create multibeneficial solutions. Giving room for water of Rijkswaterstaat, the Province of , the Water Board Amstel, dike adds protection for extreme flooding. Sluices in the levee connect the creates positive ecological effects and creates a natural form of protection Gooi and Vecht, the Amsterdam Port Authority and the City of Amsterdam. old creeks with the river. eventually in combination with a more robust levee system. The Rotterdam Together these institutions explore infrastructural and spatial measures as Centre for Resilient Delta Cities researches an practices the combination well as mitigation solutions, to reduce the consequences of flooding. The of engineering solutions for safety with climate adaptive spatial planning. climate stress test Westpoort is a pilot study within the Delta Programme We warmly welcome further questions and new cooperation with port cities Spatial Adaptation for the concrete development of a water adaptive around the globe. establishment of vital functions and vulnerable infrastructure. Based on the experiences and findings in Westpoort, spatial adaptation solutions can be MORE INFORMATION AND CONTACT: implemented more widely in the region.
