Droughts,
periods of below-normal precipitation, are a naturally occurring phenomenon
in most areas of the Droughts may be
short in duration-- such as an agricultural drought that lasts only a
few months but nevertheless devastates crops-- or they may be severe hydrologic
droughts that go on for a decade or longer, as in the case of the "mega-drought"
in American Southwest during the 16th Century. |
