In 2050, two thirds of the world‘s population will live in an urban area. Making those growing cities a safe and healthy place to live requires a drastic change in the way we build and manage them. With SDG 11 we pledge to make cities and human settlements inclusive, safe, resilient and sustainable. As science centres are frequently located in rapidly growing urban spaces, there is an unprecedented opportunity for our institutions to support the growingly diverse populations of our cities, to help address the challenges associated with this growth and to contribute to initiatives for sustainable development. This session will explore different roles that science centres play in addressing those challenges, informing the public and contributing to initiatives for sustainable development. Examples range from raising children’s curiosity, to working with youngsters to find creative solutions for real problems or involving the whole community in setting up a science centre.
