Local regression - understanding drought warnings and impact
Drought is a natural hazard which is measured and characterized by lower-than-expected or lower-than-normal rainfall. This condition, when prolonged over a longer-than-normal time period is insufficient to meet the demands of human activities and hazardous to the environment. Drought is a temporary phenomenon. Three main distinguishing features of droughts are intensity, duration, and spatial coverage. A drought early warning system can help to identify the climatic changes, understand water supply trends, and prepare for upcoming emergencies. The drought warning can help decision-makers take appropriate measures to face the upcoming challenge. They can then measure the severity of the impact and understand the underlying causes of vulnerability to reduce risk for a particular location and for a specific group of people or economic sector.
