Chad, a landlocked nation in north-central Africa, is defined by its vast expanse, from the Sahara Desert in the north to the fertile Lake Chad basin in the southwest. N’Djamena, the capital, is a growing urban center amid a country where nomadic herding and subsistence farming dominate. Chad’s oil reserves fuel its economy, but it grapples with poverty, conflict, and climate challenges like desertification. Its cultural diversity, with over 200 ethnic groups, adds richness to its stark landscapes.
