ABSTRACT

Drought in the United States: Science, Policy, and Selected Federal Authorities [September 16, 2021]   [open pdf - 2MB]

From the Document: "Drought―a deficiency of moisture that results in adverse effects―occurs to some extent almost every year in areas of the United States. Droughts can simultaneously reduce available water supplies and increase demands for water. Drought has the potential to affect economic and environmental conditions on local, regional, and national scales, as well as to cause disruptions in water supplies for households and communities. Droughts are a component of climate variability and may be seasonal, multiyear, or multi-decadal in duration. According to an August 2021 Intergovernmental Panel on Climate Change (IPCC) report on the physical science of climate change, variable precipitation and rising temperatures are intensifying droughts in some U.S. regions. According to the report, certain types of droughts, such as those causing agricultural impacts, are expected to be more likely in the western and central regions of the United States in the future."
