California
CriticalMegadrought, wildfire, and a 20-year supply gap.
California faces its driest two-decade stretch in 1,200 years. Snowpack decline, over-tapped aquifers in the Central Valley, and recurring wildfire-driven watershed damage threaten 39 million people and the nation's largest agricultural economy.
Challenges
- Colorado River supply cuts under the 2007/2024 shortage guidelines
- Central Valley aquifer overdraft causing land subsidence
- Sierra snowpack shrinking — less natural storage each year
- Wildfires destroying reservoirs and contaminating watersheds
Solutions
- Expand wastewater recycling (e.g. SoCal's Pure Water program)
- Desalination on the coast paired with strict brine management
- Groundwater recharge using stormwater capture basins
- Drip irrigation and deficit agriculture in the Central Valley
