What similar challenges do both south africa and nigeria face in the future?

Africa faces many challenges with regard to agriculture. First, in many parts of Africa, there are often droughts, which kill many crops. Economically, many African nations lack the funds to buy irrigation systems to make up for a lack of rain, as well as expensive equipment and fertilizers. Many people farm at the subsistence level, with just enough produce to feed themselves and their families. There is little surplus to store for years with lower yields.

As a result, the continent is at a high risk for famine.
