Global hunger, once decreasing, is now on the rise—especially in sub-Saharan Africa. Various factors like conflicts, economic repercussions from the covid-19 pandemic, and extreme weather events have escalated the number of undernourished people from 18% in 2015 to 23% in 2023.
Africa is home to indigenous crops that are more nutritious and better adapted to hot and dry conditions, but sadly, many of these crops have been overlooked by science. This neglect has left them vulnerable to diseases and pests while yielding below their full potential.
The challenge now is for researchers, governments, and farmers to collaborate effectively in introducing these crops into diets. This effort aims to provide energy and nutrition for Africans across all socio-economic backgrounds, enabling them to thrive despite the impacts of climate change. The full story can be found here.
