Drought
From LINKS Community Center
A drought is a period of abnormally dry weather characterized by a prolonged deficiency of precipitation below a certain threshold over a large area and a period longer than a month (WMO, 2020).
It is a weather-related natural hazard, which can affect vast regions for months or years, significantly impacting economic performance, particularly food production. Millions of people are affected by droughts each year and it is expected that vulnerability to drought will increase due to population increases, environmental degradation, development pressures and climate change.
