Question

Current predictions of rainfall change in the west have indicated that rainfall may decrease by as much as 40 cm in some areas. Imagine a savannah location that experiences 100 cm of average annual rainfall and an average annual temperature of 20°c. If rainfall decreased by 40 cm per year, what would you expect to occur?.

Answer 1

If the rainfall in this savannah location decreases by 40 cm per year, this area would become classified as a desert.

Why would this area be classified as a desert?

The maximum rainfall distribution in a subtropical desert is between 100 cm to around 60 cm while a Savannah does not receive less than 65 cm of rain in a year.

If the rainfall in this area falls by 40 cm, it will go to 60 cm per year which is less than the rainfall received in savannahs but within the range received in deserts.

In conclusion, the area would become a desert.
