[2][3] The speakers were reported to live mainly by hunting and gathering due to the climate, terrain, and unstable seasonal water supply of the Dar Fongoro area being inhospitable for intensive agriculture and animal husbandry.
They are surrounded by the Daju-Galfigé to the west, the Sinyar to the north, and the Fur-Dalinga, Fongoro, Formono, and Runga to the east and south.
[6] The language had been classified as a member of the Mubi subgroup of East Chadic by Paul Newman; however, Lionel Bender argued that its classification remained uncertain.
There may have been a mix-up with Birgit, a nearby Mubi language which is also called Kujarge; when Newman was shown the 200-word list in 2006, he would not commit to it being Chadic.
In 1981, Dutch anthropologist Paul Doornbos had spent 4–5 hours eliciting a basic vocabulary list of Kujarke from a father and son (Arbab Yahia Basi, born Ndundra, who was 35 years old in 1981) in Ro Fatá, near Foro Boranga, Darfur.
[2] Due to the war in Darfur, most Kujarke may now be living in refugee camps in the Goz Beïda and Dar Sila regions of eastern Chad.
The first time the Kujarke had been mentioned in over 25 years was when French anthropologist Jerome Tubiana had interviewed a Daju village chief in Tiero.
The chief of Tiero mentioned that a Kujarke village had been burned to the ground by the Janjaweed in 2007 during an ethnic cleansing campaign against the Daju people.
