Ngorongoro Conservation Area
In 1921, the first game preservation ordinance was passed, which restricted hunting to permit holders throughout Tanzania. In 1928, hunting was prohibited on all land within the crater rim, except the former Siedentopf farms. The National Park Ordinance of 1948 (implemented in 1951) created the Serengeti National Park (SNP). This, however, caused problems with the Maasai and other tribes, resulting in the Ngorongoro Conservation Area Ordinance (1959) that separated the conservation area from the national park. Maasai pastoralists living in Serengeti National Park were systematically relocated to Ngorongoro, increasing the population of Maasai and livestock living in the Crater. The Ngorongoro Conservation Area Authority was established by the Game Park Laws (miscellaneous amendments) Act, 1976, and owns the majority of Ngorongoro Conservation Area land, including the Crater. The area became a UNESCO World Heritage Site in 1979. The Wildlife Conservation Act of 2009 further restricted human use of Ngorongoro Crater and created a legal framework to politically disenfranchise and forcibly displace traditional pastoralists. The restriction on land use generates tension between the local Maasai communities and conservation authorities. The International Union for Conservation of Nature (IUCN) is seeking solutions to ease conflict and improve collaborative efforts towards conservation with the locals.
