In places where there was no tourism prior to tourism companies' arrival, displacement and resettlement of local communities is a common issue. For example, the Maasai tribes in Tanzania have been a victim of this problem. After the second World War, conservationists moved into the areas where the Maasai tribes lived, with the intent to make such areas accessible to tourists and to preserve the areas' natural beauty and ecology. This was often achieved through establishing national parks and conservation areas. It has been claimed that Maasai activities did not threaten the wildlife and the knowledge was blurred by "colonial disdain" and misunderstandings of savannah wildlife. As the Maasai have been displaced, the area within the Ngorongoro Conservation Area (NCA) has been adapted to allow easier access for tourists through the construction of campsites and tracks, as well as the removal of stone objects such as stones for souvenirs.
