Socioeconomic impact of 2005-2008 drought in Andalusian agriculture.

Meteorological drought is defined as the event that arises when precipitation is lower than average and initially affects rainfed crops; this is transformed into hydrological drought when persistent drought affects water storage. We have studied the economic impact of multiyear droughts by applying the economic surplus to the last severe drought (2005-2008) in Andalusia. The method is applied to both rainfed and irrigated agriculture.
