A 'polder' is a low-lying tract of land that forms an artificial
hydrological entity, enclosed by embankments known as
dikes. The best-known examples are those polders that constitute areas of
land reclaimed from a body of water, such as a
lake or the
sea, and are consequently below the surrounding water level. This requires
drainage by
pumps to prevent the water table within the polder from rising too high. Some can be drained by opening
sluices at
low tide.
Polders are most commonly found, though not exclusively so, in river deltas, former fenlands and coastal areas.
Polders and the Netherlands
The
Netherlands is frequently associated with polders. This is illustrated by the English saying: 'God created the world except for the Netherlands. The Dutch took it from the sea’''.
The Dutch have a long history of reclamation of marshes and fenland, not only within their country but also abroad. About half of all polder surface within northwest Europe is located within the Netherlands. The first embankments in Europe were constructed in Roman times. The first polders were constructed in the 11th century. From that time on the function of ''dijkgraaf'' (count of the dyke) as chair of the
Water board existed in the Netherlands. This functionary was responsible for the maintaining of the integrity of the
dykes surrounding the polder. In this function he had a large responsibility over life and death of all inhabitants, and had therefore also large powers to call upon cooperation to maintain levy integrity. The necessary co-operation between all ranks in maintaining polder integrity also gave its name to the
Dutch version of
third way politics - the
Polder Model.
