Why is much of Chad’s population concentrated outside the Sahara?

Chad’s population is primarily concentrated outside the Sahara because settlement patterns are heavily dictated by soil, climate, and the availability of water for agriculture and livestock.1

The northern part of the country lies within the Sahara, a hot, arid zone where human activity is limited to nomadic pastoralism and small-scale gardening in isolated oases. In contrast, the southern and central regions offer more favorable conditions:1

• Agriculture: The wet and dry tropical zones support the cultivation of crops such as rice, sorghum, millet, peanuts, and cotton. These areas benefit from natural irrigation provided by the Chari and Logone rivers.12
• Livestock: Central Chad serves as a hub for extensive stock raising, as the region lies beyond the northern limit of the tsetse fly, which is deadly to cattle.1
• Water Access: The Lake Chad basin has been a site of continuous settlement since 500 BCE, providing essential resources for fishing, irrigation, and diverse agricultural communities.31

Consequently, the vast majority of the population resides where these environmental factors allow for sedentary farming and sustainable animal husbandry.21
