Major population centers, especially those in areas of high seismicity, are highly vulnerable. The 2018 National Climate Assessment summarizes examples of water sector sensitivities by region. 2. Ifsignificantly less rain falls, there may be water shortages and a drought may be declared. "Beyond being of practical relevance to development practitioners and other policymakers, this work shows how much just one of the main effects of climate changemore severe and more frequent droughtswill impact especially children in poor countries, who have not contributed to the climate change problem themselves. Drought in the USAIn August 2012, drought conditions extended over 70 percent of the United States.

El Nino and La Nina are prime examples of a major fluctuation in air currents, which is often associated with drought in locations such as Africa, Australia, India, Brazil and Hawaii. This dehydrates the cells, inducing a loss of pressure. However, there are many ways to conserve water, which is becoming more and more of a priority in regions that are afflicted by drought. Drought can be defined as a period of time when a geographical region or area experiences lower precipitation and drier than normal astmospheric conditions that causes water shortage. She predicts that water problems such as drought, storms, floods, and degraded water quality will create water refugees: people migrating in search of water.
