Yvonne Aki-Sawyerr on how cities can lead on climate

Extreme weather devastated Sierra Leone’s capital city of Freetown in 2017 when torrential rains led to landslides that killed over 1,000 people. Now the city’s population is grappling with temperature increases and population swells due to people migrating from rural areas as erratic rainfall makes subsistence farming less sustainable. Freetown Mayor Yvonne Aki-Sawyerr is working to help her city adapt in areas such as building heat-resistant market shelters and building a cable car to cut down on emissions and pollution. She sat down with Devex on the sidelines of the 27th United Nations Climate Change Conference in Sharm-el- Sheikh, Egypt, to talk about the need for cities to have greater ownership on climate action. Aki-Sawyerr is ​​vice chair of C40 Cities, an organization of 96 cities focused on reducing emissions and helping their populations adapt to climate change.
