Lynette Cheah’s research group collaborates with psychologists, computer scientists and urban designers to develop smarter and more sustainable ways of city transportation. “We can’t have sustainable cities without transforming the way people move and how goods are moved around,” says Cheah, an engineering systems researcher who is based at the University of the Sunshine Coast in Queensland, Australia. Cheah outlines some challenges to meeting targets in the eleventh of 17 Sustainable Development Goals set by the United Nations in 2015 (making cities and human settlements inclusive, safe, resilient and sustainable) by 2030. In part these rely on more cities using the data-driven and centrally-planned approach taken by Singapore, the south Asian city state in which she grew up and worked until recently, she argues. Informal transport options such as tuktuk rikshaws in Thailand and shared taxi matatus in Kenya, for example, can present a barrier to delivering smarter cities, but they also have advantages. She explains why. “I am very optimistic that good science and knowledge does exist to help us, you know, track the path towards sustainable urban development,” she says. “It’ll take lots of work. It’ll take public-private partnerships. It’ll take some credible financing, lots of capacity building.” How to Save Humanity in 17 Goals is a podcast series that profiles scientists whose work addresses one or more of the SDGs. Episodes 7–12 are produced in partnership with Nature Water, and introduced by Fabio Pulizzi, its chief editor. Hosted on Acast. See acast.com/privacy for more information.
