Many urban areas in Africa do not have sufficient monitoring programs to understand their air quality. This study uses visibility as a proxy for PM pollution to provide insight into PM air pollution in three East African cities: Addis Ababa, Nairobi and Kampala, from 1974 to 2018.

Environmental groups involved in talks at a United Nations conference in Kenya have accused the US of blocking an ambitious global response to plastic pollution.

Nairobi — Elephant poaching in the country has reduced by 50 per cent, Kenya Wildlife Service said.

Yet, road safety remains a remarkably low political priority in cities around the world. In many cases, road safety is seen to be in direct conflict with other priorities, such as reducing congestion or shortening journey times.
