Why are lions roaming Nairobi's residential streets?

Residents of Ongata Rongai, a suburb in the Kenyan capital Nairobi have recently had to be on their guard after a number of lions have been sighted roaming their neighbourhood. Concern peaked three weeks ago when a video circulated of a lion climbing over a perimeter wall into a homestead – only to re-emerge with a dog in its mouth moments later. Since then the residents have received alerts from wildlife authorities, as more carnivores have been sighted. The increase in such incidents has reignited the debate over whether humans are able to live so closely to wild animals within a city. Nairobi is the only city in the world to contain a national park. For today’s Africa Daily podcast, Peter Musembi speaks to Sylvia Koira, the college student whose family dog was taken and eaten by the lioness, their homestead’s caretaker Joshua Isiga, and the BBC’s Ruth Nesoba- also a resident.
