Why does Brazil have droughts?

This year’s drought comes at the tail-end of nearly a decade of lower-than-usual precipitation, and some experts have linked this such extreme weather to climate change. Amazon rainforest deforestation also reduces evaporation of moisture that then travels on air currents to provide rainfall far afield.

Why are certain areas prone to drought?

When trees and plants release moisture into the atmosphere, clouds form and return the moisture to the ground as rain. When forests and vegetation disappear, less water is available to feed the water cycle, making entire regions more vulnerable to drought.
