4 – 8 September 2017 — ARCADIS and UN-Habitat offered a unique training opportunity for City Leaders and Decision Makers in Rotterdam and Amsterdam. This was a high-level workshop addressed to local officials and senior-level policy and decision makers focusing on cities and climate change adaptation and mitigation. The Shelter Academy was a one-week program which provides the participants with the opportunity to get their hands-on the problems faced by cities subject to climate change and environmental impacts. Participants also got the opportunity to meet with their peers, look at the variety of solutions and approaches put into practice in different contexts, and formulate action plans on cases selected by them. The workshop was enhanced by the participation of experts from Arcadis, UN-Habitat, Dutch municipalities and the IHS-Institute for Housing and Urban Development Studies of the Erasmus University in Rotterdam. The Academy promoted learning and capacity building on the topic of cities and climate change and fostered a meaningful dialogue on how cities are responding to these challenges.
