She tells co-host Indre Viskontas that better storage and reuse of the water we have—and, in the case of California, not letting that water drain into the Pacific Ocean in the first place—could drastically reduce the effects of drought. You can listen to the full interview below:

Numbers support the argument that better water and land management could curb the effects of the state’s drought. In 2014, the Pacific Institute and the Natural Resources Defense Council released a report showing that initiatives such water recycling, stormwater capture, smart irrigation, and better land management (i.e., using plants and permeable surfaces rather than turf and concrete) could help California save up to 14 million acre-feet of water per year. That’s more than the combined annual water use of all of California’s cities.

“There are always barriers. Lack of knowledge is a barrier, lack of financial incentives is a barrier,” Peter Gleick, the president of the Pacific Institute, explained to Mother Jones. “The good news is we know these things work. We know how to capture this potential…The question is: Will we?
