Groundwater pumping chronically exceeds natural recharge in many agricultural regions in California.<\/span><\/span><\/p>

A common method of recharging groundwater \u2014 when surface water is available \u2014 is to deliberately<\/span><\/span><\/p>

flood an open area, allowing water to percolate into an aquifer. However, open land suitable for this<\/span><\/span><\/p>

type of recharge is scarce. Flooding agricultural land during fallow or dormant periods has the potential<\/span><\/span><\/p>

to increase groundwater recharge substantially, but this approach has not been well studied. Using data<\/span><\/span><\/p>

on soils, topography and crop type, we developed a spatially explicit index of the suitability for<\/span><\/span><\/p>

groundwater recharge of land in all agricultural regions in California.<\/span><\/span><\/p>
