Across the WestState leaders are preparing for the long-term effects of aridification. In late April, Oregon Gov. Kate Brown Additional four additional counties to the ‘drought emergency’ tally—now, half the state is in a state of emergency. Further south, the Metropolitan Water District of Southern California, which supplies water to millions of city dwellers in Southern California, has restricted outdoor water usage For the first time ever. In Colorado, the US Department of Agriculture designated the entire state a “primary natural disaster area” due to the threat of drought—also considered an ‘unprecedented’ move. The Southwest has been hard hit by dry conditions. New Mexico and Utah issued separate emergency declarations. Water scarcity and the other for Wildfire.

The political designations allow states and counties to access resources and increase their power to deal with extreme water scarcity. This makes it possible for them to provide relief aid for the agricultural industry. Westerners will undoubtedly need it this summer, and—as the drought likely continues—future summers.

Shrinking snowpacks, parched topsoil and depleted reservoirs are symptoms of the West’s longest continuous streakSince 800 AD, there have been dry years. It is possible that the streak will continue. A study Published in Nature Climate Change in February predicted a 94 percent chance the drought stretches through 2023; the chances of it persisting through 2030 are 75 percent, when factoringIn continued impacts of a warming climate.

According to the US Drought Monitor, most of the West is in “moderate” to “severe drought.” Certain regions, like eastern and southwestern Oregon, California’s Central Valley, southern Nevada and eastern New Mexico are in “extreme” to “exceptional” drought.
