World’s cities increasingly water insecure new study shows

Abstract

With more than half of humanity now living in urban areas, the world’s cities are facing unprecedented challenges in securing water supplies. This is according to a new report by the Nature Conservancy in partnership with the C40 Cities Climate Leadership Group and the International Water Association. All cities, regardless of size, need a clean, consistent water supply to thrive, so it is little wonder that capital expenditures on water supply are large – US$90-billion a year – and growing. Unfortunately, drinking sources are increasingly insecure.
