Droughts are periods of abnormally dry weather that persists long enough to produce a serious hydrologic imbalance, causing, for example, crop damage and shortages in the water supply.
Droughts occur throughout the world. In North America, at least one region experiences drought conditions each year. We usually don’t think of droughts in the same way as other natural disasters, such as floods or hurricanes. For example, no one knows for sure how severe a drought will be - until the rains return. But droughts can be more costly than other natural disasters.
Know the Terms
Meteorological Drought - When an area gets less precipitation than normal. Due to climatic differences, what is considered a drought in one location, may not be a drought in another location.
Agricultural Drought - When the amount of moisture in the soil no longer meets the needs of a particular crop.
Hydrological Drought - When the surface and subsurface water supplies are below normal.
Socioeconomic Drought - When water supply is unable to meet human and environmental needs can upset the balance between supply and demand.
Water Restrictions - Water conservation actions that may limit hours or prohibit use of water, or require use of hand watering instead of using sprinkler systems.
