Sinking islands battle tides of climate change
Keeping the ocean at bay
The Dutch are famous for their efforts to fend off the sea - they built their first dikes to protect land from flooding more than 1,000 years ago. Today, a sophisticated system of dams and dikes allows two-thirds of the population live below sea level. Nevertheless, rising ocean levels are still a concern in the Netherlands, where there are future plans to fortify levees and build surge barriers.
