国際地理学連合
During the 1994 Congress of the International Geographical Union (IGU) in Prague, people from Poland and the Netherlands launched the idea of an International Geography Competition (iGeo) or Olympiad for students between 15 and 19 years of age. The first one was held in 1996 in The Hague, Netherlands, with five participating countries. The participant count grew to 24 countries with the 2008 competition in Carthage, Tunisia.
