Water Scarcity Index: Quantifying the Crisis
The Water Scarcity Index (WSI) is a measure of the availability of water resources in a given region. It is calculated by dividing the total amount of water available in the region by the total amount of water needed by the population. A WSI of 1 indicates that there is enough water to meet the needs of the population, while a WSI of less than 1 indicates that there is a water shortage. The WSI is used to assess the risk of water scarcity in a region and to develop policies to address water shortages.
