This is how cities around the world can avoid a water crisis

Aug 22, 2019

Residents walk near a soccer goal post on Copacabana beach after heavy rains in Rio de Janeiro April 10, 2010. The rains that started on April 5 have killed at least 205 people, most in mudslides that devastated poor hillside communities, and left thousands homeless in and around Brazil's second-biggest city. Rio Mayor Eduardo Paes signed a decree allowing the city to force residents to leave 158 locations the city deems at risk. He had already announced this week the city would remove between 1,500 and 2,000 families from two slums, meeting resistance from some residents' groups.
