Presentatie voor de Waterchallenge van de Unie van Waterschappen in LEF future centre van Rijkswaterstaat. In deze presentatie wordt ingegaan op de nut en noodzaak van het creeeren van drijvende steden met een positieve impact op de planeet en het sluiten van nutrientenkringlopen op stedelijk niveau en de transitie naar een circulaire biobased economie.

53.  A fundamental new approach to urban development
is needed for the challenges of the 21st century
 Floating city expansions combined with food
production can accommodate future urbanization
without sacrificing land
 At the same time this strategy provides global food
security and reuses waste of conventional cities
 Much research is still needed but, at the same time,
also fast implementation
 Floating cities construction is part of a wider societal
transition in which governance is crucial
Conclusions
