Ties Between The Delta And Groundwater Sustainability In California

Groundwater overdraft is a major problem globally and has been a persistent and growing problem in California for decades. This overdraft is predominantly driven by the economic value of water for agricultural production and cities. Spurred by the recent drought, California passed legislation requiring the elimination of groundwater overdraft by 2040. To explore potential water supply effects of ending long-term groundwater overdraft in California’s Central Valley, we compared several water policies with historical and warmer–drier climates, employing a statewide hydroeconomic optimization model, CALVIN, in our new paper.

How 1,500 Nuclear-Powered Water Desalination Plants Could Save The World From Desertification

About 20% of the world’s population has no access to safe drinking water, and this number will increase as the population continues to grow and global freshwater sources continue to decline. The worst-affected areas are the arid and semiarid regions of Asia, the Middle East and North Africa. UNESCO has reported that the freshwater shortfall worldwide will rise to 500 trillion gallons/yr by 2025. They expect water wars to break out in the near-future. The World Economic Forum says that shortage of fresh water may be the primary global threat in the next decade.

Agency Approves Rate Increase In Coming Year

The San Diego County Water Authority approved a water rate increase for calendar year 2020 purchases by SDCWA member agencies. The new rates approved by the water authority board June 27 will increase the cost per acre-foot on a countywide basis from $1,617 to $1,686 for treated water and from $1,341 to $1,406 for untreated supply. The increases equate to 4.3 percent for treated water and 4.8 percent for untreated water. The new rates also include an 18.3 percent increase in the Infrastructure Access Charge which is used for SDCWA fixed expenditures incurred even when water use is reduced. The water authority’s member agencies have the option of absorbing the rate increases or passing on the additional cost to customers.
