In this volume scholars from around the world discuss the innovative forms of collaboration between public and private actors that contribute to making our cities more liveable. It offers helpful insights into the practices of partnerships and the ways in which partnerships can contribute to a more liveable urban environment.  The liveability of our cities is a topic of increasing relevance and urgency. The world’s cities are becoming congested and polluted, putting pressure on affordable housing and causing safety to become a major problem. Urban governments are unable to address these major challenges on their own, and thus they seek cooperation with other governments, companies, civil society organizations, and citizens. By focusing on examples such as greenery in the city, affordable housing, safety, neighbourhood revitalization, and ‘learning by doing’ in urban living labs, this book asks two key questions. How do partnerships between public andprivate actors contribute to the liveability of cities? Under what conditions are partnerships successful, and when do they fail to yield the desired results?
