Professor Helen Dahlke, of the University of California of Davis, has been leading the (re)charge to replenish California’s groundwaters. She has teamed up with farmers, to guide the excess water from the winter rains to flood farms, thus creating temporary wetlands. Over days and weeks, that water then sinks down to replenish the aquifers. In this podcast Helen Dahlke shares about her research, the groundwater situation in California, the quest to replenish its aquifers, the droughts and intermittent large rains, the wetlands and floods, and the interdiscplinary efforts to bring back nature-based solutions to our water needs all over the world.
