What type of cities do we want our children to grow up in? Car-dominated, noisy, polluted and devoid of nature? Or walkable, welcoming, and green? As the climate crisis and urbanisation escalate, cities urgently need to become more inclusive and sustainable. This book reveals how seeing cities through the eyes of children strengthens the case for planning and transportation policies that work for people of all ages, and for the planet. It shows how urban designers and city planners can incorporate child friendly insights and ideas into their masterplans, public spaces and streetscapes. Healthier children mean happier families, stronger communities, greener neighbourhoods, and an economy focused on the long-term. Make cities better for everyone.
