On 22 March 2021, World Water Day, the Geneva Cities Hub and UN-Habitat organize, in collaboration with the Geneva Water Hub, the online debate "Water & Sanitation in the City: Good & Bad experiences, what are the lessons?" This high-level discussion is a first of a series entitled "Geneva Urban Debates". In 2017, Magnum photographer Alex Webb pictured this scene of swimmers in the Yangtze River in Chongqing, China.
