ROTTERDAM, The Netherlands — Eveline Bronsdijk knew she’d done her job when the people of Rotterdam began debating whether pigs should be allowed on rooftops.

In 2012, Bronsdijk, the city’s sustainability adviser, was trying to promote green roofs, thin layers of plants that make buildings cooler, the air cleaner and — most importantly for Rotterdam — gutters and storm drains drier.

At first, she touted how much rain the roofs can absorb, and how they could play a role in reducing the city’s increasingly chronic flooding problems. “But people don’t care about those technical aspects,” she said. “They thought it’s nonsense. Why invest in something above your head that you can’t see? Duh! End of story.”

Now Rotterdam has more than 100 acres of rooftop greenery. That’s enough to coat nearly every roof in New Orleans’ Central Business District with rain-absorbing vegetation. Rotterdam’s green roof initiative is one of a growing number of projects in Dutch cities that aim to capture and store rainwater while also making urban life more livable.
