The Hadza, or Hadzabe (Wahadza in Swahili), are a Tanzanian indigenous ethnic group mostly based in southwest Karatu District of Arusha Region. They live around Lake Eyasi in the central Rift Valley and in the neighboring Serengeti Plateau. There are, as of 2015, between 1,200 and 1,300 Hadza people living in Tanzania, however only around 400 Hadza still survive exclusively based on the traditional means of foraging. Additionally, the increasing impact of tourism and encroaching pastoralists pose serious threats to the continuation of their traditional way of life.
Genetically, the Hadza are not closely related to any other people. Once classified among the Khoisan languages, primarily because it has clicks, the Hadza language (Hadzane) is actually thought to be an isolate, unrelated to any other. Hadzane is an entirely oral language, but it is not predicted to be in danger of extinction. UNESCO states that the language is not endangered but vulnerable because most children learn it but the use is restricted to certain areas of life, for example to the home. Hadzane is also considered the most important factor of distinguishing who is and is not actually a part of the Hadza people. In more recent years, many of the Hadza have learned Swahili, the national language of Tanzania, as a second language.
As descendants of Tanzania’s aboriginal, pre-Bantu expansion hunter-gatherer population, they have probably occupied their current territory for thousands of years, with relatively little modification to their basic way of life until the past hundred years.
Since the 18th century, the Hadza have come into increasing contact with farming and herding people entering Hadzaland and its vicinity; the interactions were often hostile and caused population decline in the late 19th century. The first European contact and written accounts of the Hadza are from the late 19th century. Since then, there have been many attempts by successive colonial administrations, the independent Tanzanian government, and foreign missionaries to settle the Hadza, by introducing farming and Christianity. These efforts have largely failed, and many Hadza still pursue virtually the same way of life as their ancestors are described as having in early 20th-century accounts. In recent years, they have been under pressure from neighbouring groups encroaching on their land, and also have been affected by tourism and safari hunting.
In recent years, the Hadza’s territory has seen increasing encroachment from neighbouring peoples. The western Hadza lands are now a private hunting reserve, and the Hadza are officially restricted to a reservation within the reserve and prohibited from hunting there. The Yaeda Valley, long uninhabited due to the tsetse fly, is now occupied by Datooga herders, who are clearing the Hadza lands on either side of the now fully settled valley for pasture for their goats and cattle. The Datooga hunt out the game, and their land clearing destroys the berries, tubers, and honey that the Hadza rely on, along with watering holes for their cattle causing the shallow watering holes the Hadza rely on to dry up. Most Hadzabe are no longer able to sustain themselves in the bush without supplementary food such as ugali.
After documentaries on the Hadza on PBS and the BBC in 2001, the Mang’ola Hadza have become a tourist attraction. Although on the surface this may appear to help the Hadzabe, much of the money from tourism is allocated by government offices and tourism companies rather than going to the Hadzabe. Money given directly to Hadzabe also contributes to alcoholism and deaths from alcohol poisoning have recently become a severe problem, further contributing to the loss of cultural knowledge.
In 2007, the local government controlling the Hadza lands adjacent to the Yaeda Valley leased the entire 6,500 square kilometres (2,500 sq mi) of land to the Al Nahyan royal family of the United Arab Emirates for use as a “personal safari playground”. Both the Hadza and Datooga were evicted, with some Hadza resisters imprisoned. However, after protests from the Hadza and negative coverage in the international press, the deal was rescinded.
