A New Demand Drought Index

drought

Elius Etienne has published his work on droughts in Journal of Hydrology. He led the entire project from data collection on agriculture, climate and water use, to quality control, to developing the drought indices and validating them. The indices that he designed are an improvement over the standardized indices which do not consider water demand. This Demand-Sensitive Drought Index can be used with aggregate demand (like all agriculture) or can be utilized as a disaggregated index for a particular sectors’ water demand. He also derived drought resilience and recovery estimates for the United States. In the context of the current droughts in various parts of the country, this work can aid the policy experts in mapping the potential duration, severity, and recovery of the drought to proposed changes in demand such as agricultural water use changes and domestic supply restrictions. He has developed a website for sharing these findings. The Project App provides the background, databases and the tools and simulation modules for public understanding. He also created a quick five-minute audio slideshow on the demand sensitive drought index and its utility.
