The Anthropogenic Roots of Increased Flooding in Kano, Nigeria

by Dan McCabe

Intelligent planning for urban development requires an understanding of how different development paths can impact sustainability. In order to better understand what aspects of cities impact sustainability, Barau et al. (2015) investigated historical trends in the environmental resilience of Kano, Nigeria. Kano, northern Nigeria’s largest city with a population of over 2 million, has been a commercial center since the 10th century and has experienced extreme morphological changes in the centuries since then. Recently, the city has been subject to an increasing number of catastrophic flooding events that have caused deaths, exacerbated the spread of infectious diseases, and forced the relocation of hundreds of thousands of residents. As the frequency of extreme weather threatens to increase due to global climate change, Kano’s ability to respond to flooding is of great concern. Barau et al. therefore sought to determine how the city’s evolution has made it especially prone to severe floods. Continue reading
