Teams Across China Are Innovating to Mitigate Flooding Problems in Cities
China's drainage problem needs urgent and innovative solutions. Flooding regularly plagues 641 of the 654 largest cities, sometimes with high death tolls. And a 1-meter (3.3-foot) rise in sea levels could displace as many as 23 million people, according to the World Bank. In response, teams across 30 municipalities are tackling a massive government-sponsored program to absorb the deluge and downpours.
