Groundwater pumping is causing land to sink at record rate in San Joaquin Valley

LA Times  

For decades, a costly problem has been worsening beneath California’s San Joaquin Valley: the land has been sinking, driven by the chronic overpumping of groundwater. The study by Stanford University researchers is the first to quantify the full extent of land subsidence in the San Joaquin Valley, one of the world’s major farming regions, during the last two decades. In …

A wet year boosted California’s groundwater, but not enough to address long-term declines

LA Times  

After years of pervasive declines, groundwater levels rose significantly in much of California last year, boosted by historic wet weather and the state’s expanding efforts to replenish depleted aquifers. The state’s aquifers gained an estimated 8.7 million acre-feet of groundwater — nearly double the total storage capacity of Shasta Lake — during the 2023 water year that ended Sept. 30, …

Rapid urbanisation of Chennai Metropolitan Area will shrink waterbodies, reduce groundwater recharge potential: Study

The Hindu  

In the next four decades, tremendous changes in land use and increase in built-up area in the Chennai Metropolitan Area will not only shrink agricultural lands and waterbodies but also have an adverse impact on groundwater recharge potential in urban pockets, says a study by Anna University, carried out in collaboration with Indian Institute of Technology-Madras. The study has forecast …

Winter storms boost Central Valley water supplies, but aquifer levels remain depleted

LA Times  

Snow geese gather on a flooded farm near Dunnigan, in Yolo County, in January. The historic winter storms that filled California’s reservoirs and covered the Sierra Nevada with snow have brought a major boost to water supplies across Central Valley watersheds — an increase that measurements from NASA satellites show is the largest year-over-year gain in more than two decades …

Delhi’s water extraction rate better, says report

Hindustan Times  

The Capital extracted 0.36 billion cubic metres of groundwater in 2021-2022 but recharged 0.37 bcm during the same year, making it an extraction rate of 98.16%, an improvement from 2020-21 when the extraction rate was 101.4%, the Central Ground Water Board’s latest assessment showed. For groundwater readings, safe zones are those where the ratio of recharge to extraction is 70%, …

Recharging groundwater by water-harvesting measures

The Hindu  

When looking for a new home, one issue that is never forgotten is “how deep is the water table there”. Groundwater is the principal water source for a fourth of the world’s population. An important factor contributing to the good health of aquifers in some parts of our country is community-based movements to recharge groundwater. These slow the flow of …
