context_page_description: A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both.
  The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. 78 countries are contaminated with land mines and 15,000–20,000 people are killed every year while countless more are maimed. Approximately 80% of land mine casualties are civilian, with children as the most affected age group. Most killings occur in times of peace.
context_section_description: Metal detectors were first used for demining, after their invention by the Polish officer Józef Kosacki. His invention, known as the Polish mine detector, was used by the Allies alongside mechanical methods, to clear the German mine fields during the Second Battle of El Alamein when 500 units were shipped to Field Marshal Montgomery's Eighth Army.
  The Nazis used captured civilians who were chased across minefields to detonate the explosives. According to Laurence Rees "Curt von Gottberg, the SS-Obergruppenführer who, during 1943, conducted another huge anti-partisan action called Operation Kottbus on the eastern border of Belarus, reported that 'approximately two to three thousand local people were blown up in the clearing of the minefields'."
  Whereas the placing and arming of mines is relatively inexpensive and simple, the process of detecting and removing them is typically expensive, slow, and dangerous. This is especially true of irregular warfare where mines were used on an ad hoc basis in unmarked areas. Anti-personnel mines are most difficult to find, due to their small size and the fact that many are made almost entirely of non-metallic materials specifically to escape detection.
  Manual clearing remains the most effective technique for clearing mine fields, although hybrid techniques involving the use of animals and robots are being developed. Animals are desirable due to their strong sense of smell, which is more than capable of detecting a land mine. Animals like rats and dogs can also differentiate between other metal objects and land mines because they can be trained to detect the explosive agent itself.
  Other techniques involve the use of geo-location technologies. A joint team of researchers at the University of New South Wales and Ohio State University is working to develop a system based on multi-sensor integration.
  The laying of land mines has inadvertently led to a positive development in the Falkland Islands. Mine fields laid near the sea during the Falklands War have become favorite places for penguins, which do not weigh enough to detonate the mines. Therefore, they can breed safely, free of human intrusion. These odd sanctuaries have proven so popular and lucrative for ecotourism that efforts exist to prevent removal of the mines.
