It’s worth mentioning that Holland has reclaimed and drained a lot of land. Unlike Singapore though, the Dutch have a hinterland from which they created ‘simply’ by blocking the sea. Like the Marina barrage (which is much smaller in scale), the Aflsuitdijk runs for many kilometers and effectively created an inland lake. That is why Singapore has been learning so much from Holland.
This former Zuidersee, now cut off from the North sea would no longer be a source of flood threat to the inner provinces of Holland. But there is more.
The Dutch continued to reclaim land within this boxed up inland sea/lake and created new polders in green as you can see in the map. I recall driving along the A6 highway to Lelystad for Suan’s regular outlet mall fix. It was all on the reclaimed Flevoland.
And today the former Zuidersee has been further ‘divided’ not just for transport links, but also further risk management against the water. You see from the map that “containing” the bodies of water is a strategy, which is required given that we have climate change that could raise sea levels. Can’t stick your thumb in the dyke anymore.
Are those Dutch people strategic thinkers or what?
