When [[rain]] doesn't come it is called a drought.  [[Water conservation]] is needed before and during a drought.
 +
 +
Droughts have severe economic, health, and social effects due to disruption of [[crops|crop]] / [[food production]], [[drinking water]] supply, and other uses of water. Loss of plant/vegetation cover from droughts also contributes to [[soil erosion]] from wind and from water when rain does occur.
 +
 +
Over the past few decades, drought has contributed to widespread [[famine]], social disruption, and warfare in many developing countries, especially in [[Africa]].
 +
 +
Most researchers expect droughts to become more common over the coming decades due to [[global climate change]].
 +
 +
Long-term drought leads to [[desertification]]. 
 +
 +
Effects of drought can be mitigated in various ways:
 +
 +
*Planting of [[drought-resistant crops]]
 +
*Avoidance of water-intensive lifestyles (e.g., preferring "[[xeriscaping]]"{{wp sup|Xeriscaping}} [[landscaping]] over [[grass]] [[lawn]]s)
 +
*Use of low-water appliances (e.g. low-flush toilets)
 +
*Avoiding erosion by contouring land; planting drought-resistant [[trees]], [[bushes]], or [[ground cover]] plants to stabilize [[soil]]; use of artificial or planted [[windbreak]]s.
 +
*Recycling water through [[greywater]] systems.

==2007 drought in Tennessee, USA==
    
As of 2007 Orme, Tennessee was one of the hardest-hit communities in the drought-ridden southeastern United States, due to its dependence on two vulnerable water sources: a waterfall-fed creek and a natural spring that delivered up to 60,000 gallons/day (227,000 liters/day).  These sources dried up to only 5,000 gallons/day (19,000 liters/day), not enough to pressurize the supply lines to the town's residents.
