Innovations for floodproof ecocities: technology, design and governance

734 views

Published on

Cities in delta areas are threatened by the impacts of climate change, urbanization and land subsidence. In this presentation, the concept of ‘Flood-proof Ecocity’ has been introduced to cope with the expected challenges and to summarize recent debates about future water cities. In a ‘Flood-proof Ecocity’ urban water systems are used as a source of energy, nutrients and local water supply. There is an important role for citizens as co-producers of the urban space. Citizens will also be involved in local water supply and energy production. Surface water in Flood-proof Ecocities is used for a wide variety of functions including floating buildings and water-based urban transport. The water manager is involved from the beginning of spatial developments. To adapt cities to extreme weather events and flood risk, flood control is integrated with urban development and urban renewal. Next to technical and design elements, this presentation has presented multiple building blocks that are needed for the governance of Flood-proof Ecocities. Important elements include: improving stakeholder receptivity, improving the competitiveness of innovations, creating a commercial markets for innovations, introducing new institutional mechanisms and facilitating new roles for citizens, technical professionals and designers.
