How Wetlands Disappeared from the Netherlands in a Single Generation
June 22, 2026 · Frisian News
Between 1950 and 1990, the Netherlands lost 90 percent of its wetlands through government-backed drainage programs that turned marshes into farmland. The ecological and financial costs are only now becoming clear.
The Netherlands lost 90 percent of its wetlands between 1950 and 1990. In 1950, nearly half the country was wet. By 2000, water covered barely 6 percent. The transformation happened fast: motorized drainage pumps, government subsidies for agriculture, and a single generation of planners who saw water as a problem to solve, not a system to live with.
Dutch drainage policy came from a clear goal: turn swamp into farmland. The postwar government needed food security and exports. Water boards, given new power and new machinery, drained polder after polder. Farmers received subsidies to fell trees that held water in the soil. Dyke construction and pump technology made it cheap and fast. Nobody asked whether the country might need those wetlands back.
The damage was ecological and immediate. Wetland drainage destroyed breeding grounds for birds, fish, and amphibians. Water tables dropped. Native species vanished. The country also lost natural water storage. When heavy rains came, there was nowhere for the excess water to go. Flood risk grew as wetlands vanished.
Agribusiness and landowners profited. Grain exports became central to Dutch prosperity. The politicians who allowed this saw themselves as modernizers. Nature was the cost of progress. Local communities in wetland regions had little voice. When the water was gone, the marshes became someone else's property to farm.
Today the Netherlands tries to rewet parts of what it destroyed. It is expensive and slow. Some farmland has been bought back and deliberately flooded. But reversing fifty years of drainage takes decades. The bitter irony: a country built by controlling water now discovers it threw away water it needs.
