In the Batha region of Chad, the nomadic M'Bororo people travel the country with their animals in communities. Each year the transhumance route is marked by meteorological conditions and the country’s sometimes-dangerous security conditions in the Lake Chad region. Achta Adoum, 40, is part of this community, and she and her family regularly settle on land that allows animals to feed and drink. But since the great drought of the 1970s, water has become increasingly scarce. Achta tells me "that animals provide less than a litre of milk a day whereas before we could sell 3 times more milk. Not to mention the roadblocks that prevent access to some of the more fertile areas, it is also necessary to travel more kilometers to find a place to stop”.
