What is the variability of rainfall in Africa?
- The amount of rainfall in parts of the Congo Basin is much less variable, with a coefficient of variation around 10–15 percent. For most of the continent where rainfed crops are prevalent, the variability is 15–35 percent. Why is this important? In Africa, where most agriculture is rainfed, crop growth is limited by water availability.
