Drought <=SEP=> A drought is a period of below-average precipitation in a given region , resulting in prolonged shortages in its water supply , whether atmospheric , surface water or ground water . A drought can last for months or years , or may be declared after as few as 15 days . It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy . Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent bush fires . Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour .   Many plant species , such as those in the family Cactaceae ( or cacti ) , have drought tolerance adaptations like reduced leaf area and waxy cuticles to enhance their ability to tolerate drought . Some others survive dry periods as buried seeds . Semi-permanent drought produces arid biomes such as deserts and grasslands . Prolonged droughts have caused mass migrations and humanitarian crises . Most arid ecosystems have inherently low productivity . The most prolonged drought ever in the world in recorded history occurred in the Atacama Desert in Chile ( 400 Years ) .
