One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. 

Join us for The Future of Water, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts, and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Join us for The Future of Water Workshop, to explore our water future, with highlights including a keynote from Peter Gleick, one of the world’s leading water experts (all guests will receive a copy of Peter’s most recent book, The Three Ages of Water) and Mimi Casteel, not only a viticulturist and winemaker, but also a forest ecologist with a vision for water resiliency.

Wine grape quality is closely tied to the right amount of water, at the right time. One of the most critical agricultural concerns with our changing climate, and more frequent & intense weather extremes, is precipitation and water availability. We’ve swung from historic drought to atmospheric rivers. Our community has huge swaths of unmanaged, unhealthy forests full of non-natives and overrun by firs, amplifying fire risk and undermining one of the most critical systems for groundwater recharge.

The good news is opportunities abound to optimize irrigation efficiency, and implement regenerative practices that improve soil health, water infiltration, and retention. A watershed coalition has also formed in Napa County to pilot and model creek & forest restoration for localized water resiliency and climate cooling. 

Come learn more on Thursday, May 23rd at 9:00am at @silveroakcellars.
