Dry earth as a result of a drought in the Sonoran Desert, Mexico

Drought is a continuous period of dry weather, when an area gets less than its normal amount of rain, over months or even years. Crops and other plants need water to grow, and land animals need it to live. It can become dangerous to people and other animals; causing famine and even creating deserts.

A drought is a natural event, caused by other weather events like El Niño and high-pressure systems. Drought can also be triggered by deforestation (people cutting down forests), by global warming, and by diverting rivers or emptying lakes.

Drought is a disaster which usually takes place slowly. It is often difficult to decide when a drought started and sometimes when it ends too. Its effects often build up slowly over a long period of time and may last from months to years after rain resumes.

Many people die every year in famines due to drought in subsistence farming areas. Conflicts can result from drought conditions.[1]
