Why are many Africans south of the Sahara malnourished even though most are farmers?

Several factors contribute to malnutrition among farmers in Africa south of the Sahara, including limited access to resources such as quality seeds, fertilizers, and irrigation systems, as well as unpredictable weather patterns and climate change affecting crop yields. Additionally, poverty, food insecurity, inadequate infrastructure, and poor healthcare also play a role in exacerbating malnutrition in this region.
