In your text, treat Africa as if it were one country. It is hot and dusty with rolling grasslands and huge herds of animals and tall, thin people who are starving
This reminds me of the discussion we had in class last week about preconceptions on the Sahara. The fact in this age of modernization, technology and internet, many people still think of Africa as a country, of Africans as people living the jungle, with animals (I have friends who have been asked this), or of the Sahara as no man's land shows how powerful historical accounts can be and how important it is then to be as accurate as possible.
