Welcome to the World Water Quality Alliance Conference 2022. The aim of the event is simple: To demonstrate that local communities are key to the overcoming of global water-based challenges. The World Water Quality Alliance, convened by the United Nations Environment Programme, has organised this event to promote local dialogue, engagement and exchange, to highlight how the data generated by the World Water Quality Assessment can be transformed into practical local action and how, as a result, local society can maintain a permanent dialogue with decision-makers at a supranational level.
