Question

Summary of the Drought​

Answer 1

Drought is an insidious natural hazard that may cause tremendous loss to agriculture, ecosystems, and other sectors. Reliable drought monitoring and early warning are important for drought preparedness planning and mitigation to reduce potential impacts, especially for early famine warnings. Traditionally, drought monitoring is usually based on drought indices.

Drought is a creeping natural hazard that results from a deficiency of precipitation (runoff, soil moisture) from long-term average (over at least 30 years), which is referred to as a normal value.
