There is a direct connection between the future of the city and the key challenges of our time, such as climate change and rapidly growing social inequality. Over the next three years, the IABR will fully focus on finding a missing link in the effort to uncover solutions: the gap between innovative design and sustainable realisation. Stimulating an environment in which good plans can be turned into concrete projects is a vital part. Published with the 8th International Architecture Biennale Rotterdam, this catalogue starts with the Delta of the Low Countries, with research and ateliers in Belgium and the Netherlands, and exhibitions and programmes in Rotterdam and Brussels.
