California\u2019s <a href=\"https:\/\/www.kqed.org\/news\/tag\/central-valley\" rel=\"nofollow noopener\" target=\"_blank\">Central Valley<\/a> have sunk by more than 11 feet in recent years because of groundwater pumping, the extraction of water from underground aquifers using wells and electric pumps for drinking, farming and industry.\u00a0<\/p>\n<p class=\"blocks-v1-Paragraph-__Paragraph__paragraph wp-block wp-block-paragraph container\">While some land subsidence is temporary, excessive pumping can cause aquifers to permanently collapse, reducing storage capacity and damaging homes, roads, bridges and canals.<\/p>\n<p class=\"blocks-v1-Paragraph-__Paragraph__paragraph wp-block wp-block-paragraph container\">New research from UCLA and Caltech has outlined a way to detect when temporary land subsidence becomes permanent and irreversible.<\/p>\n<p class=\"blocks-v1-Paragraph-__Paragraph__paragraph wp-block wp-block-paragraph

href=\"https:\/\/www.pnas.org\/doi\/full\/10.1073\/pnas.2526041123\">published this week<\/a> in Proceedings of the National Academy of Sciences, uses satellite imagery to identify the \u201cabrupt transition to irreversible damage.\u201d Researchers hope this will give decision makers new tools to keep an eye on water resources.\u00a0<\/p>\n<p class=\"blocks-v1-Paragraph-__Paragraph__paragraph
