How do the Dutch use polders?
They first build dikes around some immersed land, then pump the water out of it (formerly using windmills), then use it for growing crops.
Which counrty has polders reclaimed from the sea?
There are over a dozen countries that have polders, but Holland (also known as the Netherlands) has the most and is the country most famous for them. Because so much of the land lies below sea level, it is necessary to build dikes or embankments to hold back the ocean water and prevent flooding. The Dutch first started building polders about a thousand years ago and there are now about 3,000 in their country. Polders are low lying tracts of land usually protected by embankments or dikes. Comes from a Dutch word 'poire' Land claimed from water covered sources, lakes and seas.
