The Sustainable Groundwater Management Act (SGMA) was designed around localized decision making — each Groundwater Sustainability Agency (GSA) adapting to the hydrology, economics, and politics of its own basin. But that strength creates a blind spot: it can be a significant challenge for myriad stakeholders to maintain a clear picture of the evolving policies and projects unfolding across the state.
WaterOne.ai attends hundreds of GSA board meetings every month and uses artificial intelligence (AI) to synthesize discussions into a searchable database, weekly digests, podcast summaries, and a “ChatGSA”. The result is a unique, cross-basin view of SGMA implementation as it unfolds — from allocation changes and fee structures to recharge projects and compliance timelines.
In this session, Ryo Takanashi will share patterns emerging across GSAs, discuss the persistent gap between boardroom decisions and the growers who need to act on them, and demonstrate how making this information accessible can support more coordinated groundwater management across California.
Why This Matters
SGMA is playing out differently in every basin — but the people who need that information most often can’t access it. This session offers a rare statewide lens on how California’s landmark groundwater law is unfolding in practice, where the gaps are, and how AI tools are starting to close them. If you work in groundwater management, agricultural water use, or water policy, this one’s for you.
About the Speaker
Ryo Takanashi brings a rare combination of global supply chain expertise and water policy insight to the challenge of groundwater governance. He spent the first decade of his career managing agricultural supply chains as the youngest Chief Corn Trader at Japan’s largest commercial importer, overseeing 20 percent of the country’s corn imports — and witnessing firsthand how weather volatility and water scarcity ripple through global food systems.
That experience led him back to academia at Stanford, where he co-founded Project Mizu and produced the world’s first comprehensive taxonomy of water-agriculture adaptation solutions, endorsed by an IPCC author and UN FAO country head. Today, as Co-Founder of WaterOne.ai, Ryo focuses on the other side of the problem: keeping the people who make water management decisions — and the growers who live by them — actually informed. WaterOne.ai is a proud member of the Stanford Sustainability Accelerator, StartX, ImagineH2O, and Fresno State Valley Ventures cohorts.
