Imo State in southeastern Nigeria has over 780 active erosion sites, slowly swallowing farmlands and homes. While experts know the causes, soft soils, heavy rains exceeding 2,500 mm yearly, and fast urban growth, few studies have linked physical danger to people’s real struggles. This study maps erosion risk using satellite data and conversations with nine severely impacted communities including Nekede and Amucha. The study found that cities like Owerri face the highest danger because paved surfaces push water into vulnerable areas. In western districts like Oguta, crowded land and natural drainage patterns worsen the crisis. Farmers, who make up 70 percent of the population, have lost about one fifth of their arable land, threatening food security. This work gives local leaders a practical tool to protect lives and livelihoods before more land disappears.
