Groningen is one of the smaller provinces of the Netherlands in terms of surface area.
In the seventies, Groningen was world famous as the breadbasket of Western Europe with various monocultures. In addition, there is quite a bit of animal husbandry. At over 80%, it still has an exceptionally large number of agricultural areas.

The reduction of the pressure in the underground layers leads to a measurable drop in the surface level and regularly to non-natural earthquakes.
