The Sustainable Groundwater Management Act, passed by the California legislature in 2014, requires local agencies to create plans for sustainable management of local groundwater basins.
A new white paper published by the Union of Concerned Scientists and the Water in the West program at Stanford University finds that, of two dozen local management plans submitted to the state earlier this year, nearly half did not include a quantitative analysis of climate change, even though required to by law.
The authors found that many agencies were not using appropriate climate data in their plans. They wrote the white paper in order to provide guidance to local agencies to help them better incorporate climate change into their planning efforts. This includes a four-step process to incorporate climate projections into their groundwater sustainability plans.
