The multiple land use philosophy in the Area is to maintain the peaceful co-existence of human and wildlife in a natural and traditional setting. Pastoralism, conservation of natural resources and tourism are the three, main components that are given equal consideration in policy shaping decisions. The NCA aims for the historic balance of people and nature in a way which has not been possible in many parts of the world. At stake are the rich bio diversity and ecology of the Serengeti plains and the Ngorongoro Highlands, the major paleontological and archaeological sites and important water catchment areas. Tourism is a vital element in raising revenue and has been encouraged and developed with a respect for culture and without damaging the environment. Man and his ancestors have lived in the Ngorongoro eco-system for more than three million years.
Ngorongoro Conservation Area became a UNESCO World Heritage Site in 1979. Two years later, in 1981 Ngorongoro Conservation Area was given another status: Man and International Biosphere Reserve. In 2010 Ngorongoro Conservatin Area was inscribed as a cultural property on the World Heritage List hence becoming a UNESCO MIXED WORLD HERIATGE SITE. The NCA is the only site in the world with a high concentration of wildlife living with human communities. The multiple land use systems in this area are among the earliest to be established around the world as a means of reconciling human development and conserving natural resources. The NCA also contains numerous paleontological, archaeological, and anthropological sites of exceptional quality
