The three-year drought in California is making history, and not in a good way. It's officially the worst drought on record for the state, already costing over $2 billion and 17,000 jobs.
Now start-ups from Silicon Valley, like the neighboring farms and residents, are trying to alleviate the problem.
At the Francis Ford Coppola Winery in Geyserville, California, the company's head of grower relations, Lise Asimont, says the drought is a huge concern and worries that if this three-year drought stretches to four or five years there will be even more significant problems.
"It could be a compounding issue for us that could keep continuing on and if that should happen, perhaps in a couple of years we would really see the impact on wine grapes," she tells CNBC.
The winery has teamed up with start-up TerrAvion, which has received funding from incubator Y-Combinator, a company that flies manned aircraft over farmland and gives growers thermal images that can show farmers potential trouble spots when it comes to irrigation.
TerrAvion's CTO, Cornell Wright, says demand for its services is strong. "We see a lot of interest from growers because of the drought, and it definitely helps them find irrigation leaks and manage water more effectively."
