drought indices

Drought indices are tools used to measure and monitor drought conditions by analyzing weather and soil data over time. They help determine how dry an area is, considering factors like rainfall, soil moisture, and water supply. These indices provide valuable information to decision-makers, farmers, and water resource managers to understand drought severity, plan responses, and manage water resources effectively. Different indices focus on various aspects of drought, such as soil dryness or overall water availability, enabling a comprehensive assessment of drought impacts on the environment and society.
