Before the middle of this century, the world's cities will face challenges like never before. A projected 50% growth in world population, hand-in-hand with the concentration of people in urban centres, means our cities will have to be prepared for the social, environmental and infrastructural challenges coming their way. 100 Resilient Cities ([100RC](http://www.100resilientcities.org/)) is an organisation dedicated to helping cities around the world become more resilient to the physical, social and economic challenges of today and the future. From Accra to Yiwu, cities around the world are supported in their distinct challenges by 100RC. We speak with Elizabeth Yee, the Vice President of City Solutions for 100RC and help us to ask what we can learn from how cities are overcoming resilience challenges.
