New Research: “Demand Sensitive” Drought Index


Research from Columbia Water Center scientists and affiliated researchers has yielded a new “demand sensitive” drought index. Unlike the many existing indices, which are essentially supply-based, this index is the first to directly connect existing or projected water demand to the potential water deficit during a drought.
