What the Netherlands has done – and is urgently planning to do – in the face of climate-driven sea-level rise holds important lessons for the rest of the world.
The Dutch enjoy a hard-earned reputation for building river dikes and sea barriers. Over centuries, they have transformed a flood-prone river delta into a wealthy nation roughly twice the size of New Jersey.
If scientific projections for global warming are right, however, that success will be sorely tested. Globally, sea levels may rise up to a foot during the early part of this century, and up to nearly three feet by century's end. This would bring higher tidal surges from the more-intense coastal storms that scientists also project, along with the risk of more frequent and more severe river floods from intense rainfall inland.
Nowhere does this aquatic vise squeeze more tightly than on the world's densely populated river deltas.
So why is one of the most famous deltas – the Netherlands – breaching some river dikes and digging up some of the rare land in this part of the country that rises (barely) above sea level?
In the Biesbosch, a small inland delta near the city of Dordrecht, ecologist Alphons van Winden looks out his car window at a lone excavator filling a dump truck with soil. He considers the question and laughs. "We do have a hard time explaining this to foreigners," he says.
The work here represent a keystone in the country's climate-adaptation plans, Mr. van Winden says. Indeed, nowhere are adaptation planning efforts to address rising sea levels and flooding more advanced than in the Netherlands.
To be sure, the country's economic wealth and long experience dealing with threats from seas and rivers give it an advantage over other low countries that face rising waters, such as Bangladesh, Vietnam, and the tiny tropical island nation of Tuvalu in the South Pacific. But many of the approaches the Netherlands is taking can and are being slowly adopted even in countries far poorer, specialists say.
