Deserts and semi-desert Covers 2/5 of Africa Namib Desert – coast of Namibia, SW Kalahari Desert – Southern plateau,

covers most of Botswana vegetation – cactus, shrubs temps vary from 120°-50°F

plains Seasons – long dry one, short wet one Less water in recent years – caused

by drought Problems – famine, death, migration

Tropical Rainforests cover 8% of Africa located near equator Rains daily poor farmland

Soil gets leached – nutrients washed away products from rainforest
