The giant statues of the three white-cap chiefs known as Agba Meta that greet travellers at the toll gate remain a monumental symbol when entering Lagos. However, what follows next is far less welcoming — heaps of refuse dumped along the roadside, open gutters clogged with waste, and the occasional stench from makeshift dumps or open defecation sites. For a megacity of more than 18 million people, with about 6,000 visitors arriving daily, Lagos struggles to manage the waste it generates. The city may boast some of the best infrastructure in Nigeria, but its waste management system remains in a troubling state.
