And the future of the global urban population will depend on how we tackle the great challenges of our lifetime: climate change, massification, traffic congestion, affordable housing, education and health, inequality, social justice.

The current global context shows that going solo is not an option anymore. The key to a brighter future lies in accelerating sustainable and inclusive cities all over the globe, together.

To do so, we need experts, citizens and organizations playing together like an orchestra. Envisioning and pushing forward plural, inclusive solutions. Being intentional and open-handed. Responding with collaborative approaches to the complex problems cities face.
