It’s a short drive to witness the human devastation caused by the climate crisis on the outskirts of Bujumbura in Burundi.
The first signs of catastrophe are found in the recently abandoned hotel and mansions, where lake water has soaked into the lower floors and laps through car parks. A little further west along the corniche that, until recently, swept behind the smartest plots in this impoverished nation, the road itself becomes a causeway. On the left, old men chat as they sit in plastic chairs with their feet on beer crates – the water has come, and it won’t go away.
