Who are the residents of our cities, and what rights do they have? By escaping an anthropocentric mindset, we will explore and imagine a world that goes beyond human stakeholders. We will trace and analyse humans, the built environment and its technologies, as well as non-human nature within an urban context. What interactions exist, and how, if at all, can possible conflicts be solved? We will jointly draft a manifesto to summarise our findings and reframe the perception, design and code of urban co-existence.
