A third of my country is under sea level and the government has been putting holes in the dykes across the country. Supposedly for some fauna reason and to make the dunes behind the dykes wider. I have no knowledge on this topic so I wanted to see if there is some amazing knowledgeable nostrich that knows more or can point me in the right direction?

What’s up with this? Feels kind of dangerous at first glance.
