Food security in Africa: managing water will be vital in a rapidly growing region

Sub-Saharan Africa’s population is growing at 2.7% per year and is expected to reach two billion by the year 2050. The region’s urban population is growing even faster: it was at 533 million in 2023, a 3.85% increase from 2022.

The need to feed this population will put pressure on land and water resources.

I’m part of a group of researchers who have looked at whether regional food production would be sufficient to supply growing urban populations. By and large, we have found high levels of food self-sufficiency. But climate change could put a spanner in the works.
