This book describes the climatic conditions that give rise to droughts, and their various forms and chief attributes. Past droughts are described including those that had severe impacts on human societies. As a disturbance, droughts can be thought of as "ramps" in that they usually build slowly and take time to become evident. As precipitation is reduced, flows from catchments into aquatic systems decline aZoology aAnimals aArthropoda aFreshwater ecology. aSCIENCE -- Life Sciences -- Ecology. aEarth & Environmental Sciences. aMeteorology & Climatology. aaquatic ecology aHealth & Biological Sciences. aLake, P.
