What is a drought?

Drought (Hugh Harris)

Droughts are not very easy to define. A drought is not just a lack of water for a significant period. It is difficult to come up with a single definition as drought varies from place to place. A severe drought in the Indian monsoon, such as that during the 2002 season, can be caused by just a few weeks of deficit rainfall. In south-east Australia, rainfall amounts have been below normal for about a decade, leading to an extended drought which has affected farming practices and has led to a series of wildfires in populated areas. In the UK people say there is a hose-pipe ban if it doesn’t rain for 14 days! In fact, there are a whole range of types of drought including; agricultural (farming), meteorological (weather), hydrological (surface water) and socio-economic (ones which affect humans).
