Kenya nairobi flooding – As Kenya’s capital city, Nairobi, grapples with the devastating effects of recurrent flooding, this comprehensive guide delves into the intricate web of factors contributing to this urban crisis, its far-reaching consequences, and the urgent need for innovative mitigation strategies.
Nairobi’s geographical location, rapid urbanization, and the impacts of climate change have coalesced to create a perfect storm, exacerbating the severity and frequency of flooding events. The ensuing social and economic consequences have been profound, affecting housing, infrastructure, transportation, and public health.
Causes of Flooding in Nairobi
Flooding in Nairobi is a complex issue with multiple contributing factors. Geographical features, urbanization, and climate change all play a role in the city’s susceptibility to flooding.
Geographical Factors
Nairobi is situated in a valley surrounded by hills, which restricts the flow of water during heavy rainfall. The city’s drainage system is often overwhelmed by the volume of water, leading to flooding.
