The report is informed by a collaboration between ULI and the city of Rotterdam, which is seeking to foster an innovation ecosystem as part of the modernisation of its economy and the re-development of its central station area and the port lands. It partnered with ULI to organise a one-day workshop that brought together an international group of practitioners working on urban innovation districts to help devise a longer-term strategy for the city to build its innovation capacity. It also draws on the different approaches taken in three cities (Munich, San Diego and Tel Aviv), which are featured—along with Rotterdam—as separate case studies. The report builds on ULI’s growing body of work on technology and the impact of the innovation economy on real estate.
