The increasing volume of solid waste, driven by Nairobi's growing population, has become one of the city's major challenges (Ref 1, 2). To address this issue and promote better environmental practices, authorities plan to convert all reclaimed illegal dumpsites into recreational and green spaces. The transformation of the former Kangemi Cemetery, abandoned for over 20 years and used as an illegal dumpsite, was the first initiative in this effort. Led by Nairobi's Governor, H.E. Mike Sonko, and supported by the City County, the project was completed in 2018 and serves as a key example of these transformative measures (Ref 1, 2, 3). Previously, Kangemi Cemetery contained over 500 loads of illegal waste, but following a successful clean-up, it has been rehabilitated into a children's playground with recreational area, now named Kangemi Cemetery Memorial Park (Ref 3).
