The authors would like to thank all those who participated in interviews, particularly the technical teams from city administrations, who gave up their time to provide valuable insights from their experiences of waste management in their cities. In particular, we would like to thank the teams in Freetown and Kanifing for their extensive support in researching these case studies, including Ousman Gaye and Philip Spencer for facilitating many discussions with the technical team in Kanifing. Additional thanks go to A. Mohammed A. Foboi, Fredrick Cole, Edwin D. Johnson and Massa Stubblefield (Monrovia) and Moses Quarshie (Accra) for their support and inputs. We would also like to recognise Nandini Sharma, Olive Leonard and Kato Kimbugwe for their research assistance.
