California's most recent drought - which officially ended this spring -made national, even international news.
"We're in an historic drought / The driest on record
One of the worst droughts in recent history / California is in big trouble."
And that saturated coverage may have actually influenced Californians to conserve more water-
compared to an earlier drought, from 2007 to 2009, which snagged far fewer headlines.
Researchers tallied all drought-related stories from nine major newspapers from 2005 to 2015.
They also counted Google queries, and saw drought-related searches spike as more news appeared.
Then they analyzed water use in the San Francisco Bay Area.
And after controlling for other factors-like weather and unemployment-
they found that drought news was significantly linked to a cut in water waste:
up to an 18 percent drop per 100 news articles in a two-month period.
The results are in the journal Science Advances.
Study author Newsha Ajami, a hydrologist at Stanford University,
says more water news-from any source-is good for consumers.
"Obviously it's great the media's covering this drought,
but on a non-drought or non-emergency situation, water agencies can actually step up their education and outreach efforts
and create a more sort of two-way communication stream between them and their water users and customers."
So that the next time the state dries up, residents might more readily turn off the tap.
