In 2014, the Rockefeller Foundation took the initiative to set up 100 Resilient Cities - with Rotterdam as one of the first members. Six years later, it is time for the next step: a network managed by the cities themselves that is more focused on action and implementation than before. This next phase was announced at the 10th World Urban Forum, from 8-13 February 2020 in Abu Dhabi. The new brand name of the Global Resilient Cities Network is expected to be officially announced in May. Arnoud Molenaar, Chief Resilience Officer in Rotterdam and member of the global steering committee, sees plenty of new opportunities for the cities and for the Dutch water sector.
