Go with the flow: Using nature to help fight climate change
The Netherlands have to think ahead. If they don't, this country will simply disappear under the waves. And that makes prevention really part of the DNA of this country.- Tracy Metz
Since the 1990s, the Netherlands has been looking at softer approaches to help fight climate change, mainly by using the forces of nature.
"We are seeing that the consequences of those interventions are now coming back to bite us in the heels," says Tracy Metz, a Dutch-American journalist. "And as the climate becomes more irregular, there are more extreme events, it rains harder... more glacial water melts and comes roaring down the rivers and there's no place for it to go. We've tightened the rivers into very efficient navigation channels, which means that there's really nowhere for the water to go. Those are the two most important reasons for the Dutch to start figuring out a softer, more natural, more accommodating approach to water."
The new approach is called Building with Nature. That means cutting dikes instead of making them higher, and letting nature do some of the heavy lifting instead of building a wall to keep the water out. The Room for the River project involves 30 different interventions along the major rivers flowing through the Netherlands, and is essentially a flood control project that allows rivers to flood, instead of forcing the water to go where it wouldn't naturally go. The project, which cost 2 billion euros, involved buying out farmers and homeowners along those rivers to give more space to the water, but also involves improving urban design along the water.
Another large-scale project in the Netherlands is the Sand Engine, a massive pile of sand along the coast near The Hague. The sand was placed there in the shape of a teardrop, and over a period of about 20 years, the waves, wind and currents will gradually spread the sand along the coast to help prevent erosion.
The Dutch approach isn't just confined to the Netherlands, though. In Pamplona, which has seen flooding increase over the years, Park Aranzadi was redesigned to accommodate the flooding, and has changed the public's perception of flooding from a threat, to a natural part of the life of a river.
