Giant Gullies Swallowing African Cities

Massive gullies are opening up in African cities, swallowing homes and businesses, displacing hundreds of thousands. A new study reveals that an average of 118,600 people in the Democratic Republic of Congo alone were displaced between 2004 and 2023 due to these expanding fissures. The problem stems from a combination of natural and human factors—cities built on sandy soils with inadequate drainage systems, leading to erosion during heavy rains. Unless urgent action is taken, millions more could be displaced in the next decade. Researchers urge increased investment in improved drainage, sustainable infrastructure, and community engagement to find effective and long-term solutions.
