Despite facing huge disaster risks, Mozambique is the 13th least prepared country for the effects of climate change.
There are many ways that Maputo, and Mozambique more generally, could adapt to the worst impacts of extreme rainfall. “Grey” infrastructure such as drainage canal retention basins and protective walls can work alongside “nature-based solutions”, such as mangrove reforestation and planting dune vegetation, which prevent land erosion during flooding. As is often the case, the question here is not how will Mozambique adapt to climate change, but rather, who will foot the bill?
