Drought Severity Index
The Drought Severity Index (DSI) is a tool that measures how dry or wet an area is compared to normal conditions. It considers factors like soil moisture, rainfall, and water availability to assess drought intensity. A higher or more negative DSI indicates more severe drought conditions, meaning the land and water sources are significantly drier than usual. This helps authorities and scientists monitor drought impacts, plan water management, and make decisions to mitigate drought effects on agriculture, ecosystems, and communities.
