Drought: Unit Overview part of EarthLabs:Drought
Drought is an ever-present threat to all people whose lifestyles have been built on the availability of water. Across the planet, millions of humans make their homes and grow crops in areas that receive minimal amounts of precipitation. In this EarthLabs module students learn that when precipitation drops below normal, drought conditions can develop and economic, environmental, and social impacts can follow. The unit teaches students to interpret climate data to recognize the symptoms and evaluate the severity of drought. The unit raises awareness of the need to be prepared to face drought conditions that may become more common as our planet warms.
