From Farms to Cities: Percolating New Ideas for Water Security

Sustainable Conservation a non-profit and IoES practicum client partner produced this video from an event held Sept 6, 2017 Following winter rains that pummeled the state, it’s easy for California’s five-year drought to recede in our memories. Resisting that amnesia is essential to our Golden State’s water future. We will explore how farms and cities...
