Netherlands farmland reclamation

Polder: A polder is reclaimed land from a body of water protected by dikes. It's like creating an island within an ocean but instead it's used for farming or living purposes.

Dike/Levee: These are barriers used to prevent flooding from rivers or seas. They act as walls keeping the water at bay.

Windmill: Historically, windmills in Netherlands were used to pump water out of low-lying lands. They are like giant fans that instead of blowing air, they move water.
