Reader's Guide
The Kalahari Desert's significance lies in its complex climatic history and ecological richness. During wetter phases, it supported large mammals such as antelopes, elephants, and hippopotamuses, alongside diverse savanna and woodland plants. The only permanent river, the Okavango, flows into a delta in the northwest, forming wildlife-rich marshes. Ancient dry riverbeds called Ouramba provide standing pools during the rainy season. The Kalahari supports more animals and plants than a true desert like the Namib, with vegetation cover ranging from semi-desert in the southwest to denser savanna elsewhere. Its climate is subtropical and semi-arid, with a dry season from April to September and summer rainfall often accompanied by heavy thunderstorms.
