The Drought Severity Index

The Drought Severity Index (DSI) measures the intensity and duration of drought conditions in a specific area. It combines data on rainfall, soil moisture, and water supply to assess how dry a region is compared to normal conditions. A higher DSI indicates more severe drought, affecting agriculture, ecosystems, and water resources. It helps policymakers, farmers, and emergency officials understand drought impacts and make informed decisions about water management and disaster preparedness. The DSI provides a standardized way to monitor and compare drought conditions over time and across different locations.
