To Avoid Future Mudslides, Sierra Leone Must Tackle Unplanned Urbanization

Wednesday, Aug. 23, 2017

The death toll from last week’s devastating mudslide in Sierra Leone is likely to pass 500, with several thousand more people made homeless by the destruction left in its wake. The scale of the disaster was unparalleled, but flooding in the capital, Freetown, happens every year during the August rainy season. In 2015, at least 10 people were killed in the city by rising water; Kroo Town, one of Freetown’s largest unplanned neighborhoods, or informal settlements, has flooded every year since 2008. The major cause of the mudslides and flooding, according to Joseph Macarthy of the Sierra Leone Urban Research Centre, is “the chaotic development caused by the rapid urbanization of Freetown . . . exacerbated by the fact that town planning is almost nonexistent.”
