Subsidence of land surfaces has increasingly become a greater concern around the world as groundwater has continued to be depleted due to increase water demand while surface water depletion means that populations increasingly look to use subsurface water.
The lowering of Earth’s land surfaces promises to be a major problem for urban and rural regions and mapping these threats accurately may prove important to plan, prevent, and minimize this threat.
Using a literature review and spatial analysis, it is evident that some 34 countries are at major risk in the coming decades for major subsidence of their land surface. In particular, a recent mapping effort that looks at every 30 arc seconds resolution across the globe identified that very flat areas with unconsolidated sediments accumulated in alluvial basins or coastal plains are the most vulnerable.

Department of Conservation awards $1.5M in grants to support State’s Groundwater Management Plan
“The California Department of Conservation (DOC) today announced five watershed coordinator grants totaling $1.5 million to support regional sustainable groundwater management goals. The grants will go to organizations around the state within medium- and high-priority groundwater basins. “California’s world-class economy – its unparalleled agricultural sector, diversity, and abundance of industry and communities of all sizes and geographies — depends on water, and with the reality of climate change, that increasingly means groundwater,” DOC Director David Shabazian said. “Groundwater is a critical resource that we must manage more intently to meet today’s needs while also ensuring adequate water supply in the future. These grants, which support the goals of the Sustainable Groundwater Management Act (SGMA), help us do that.” … ” Read more from the Department of Conservation here: Department of Conservation awards $1.5M in grants to support State’s Groundwater Management Plan
Managing groundwater overdraft – combining crop and water decisions (without salinity)
” … This post summarizes some recent research examining conjunctive water management for agriculture integrating hydro-economic optimization models on two timescales, neglecting for now salinity effects on crop yield: an intermediate term 10-year stochastic model of water and crop management spanning dry and wet years, and a far horizon (100 years of 10-year stages) management model which embeds intermediate-term model to represent longer-term aquifer targets (Yao 2020). The modeling was applied for conditions similar to California’s San Joaquin Valley. Integrated economically-driven optimization of permanent and annual crop acreages and water management for these two timescales identifies some economically-promising strategies considering both crop decisions and water management to mitigate groundwater overdraft. … ” Read more from the California Water Blog here: Managing groundwater overdraft – combining crop and water decisions (without salinity)
Dusty barren fields or thriving farmland and habitat? This bill creates a better vision for California’s future
“[On Friday], Assemblymembers Robert Rivas (D-Hollister), chair of the Assembly Agriculture Committee and vice-chair of the California Latino Legislative Caucus, and Rudy Salas (D-Bakersfield) introduced a bill, AB 252, to help farmers and rural communities adapt to more sustainable groundwater use while simultaneously creating new benefits for people and wildlife. AB 252, sponsored by EDF, will help create opportunities on these previously irrigated agricultural land and ease the transition to sustainable groundwater management. It will create a new program through the California Department of Conservation to provide incentive payments to landowners who voluntarily and strategically repurpose at least some portion of their agricultural land to other less water-intensive uses for at least 10 years. … ” Read more from EDF’s Growing Returns here: Dusty barren fields or thriving farmland and habitat?

Delano’s “big dig”
“The state’s new groundwater law has prompted a lot of dirt movement in the Central Valley. The Sustainable Groundwater Management Act passed in 2014 mandates that overdrafted water basins get their aquifers in balance — don’t pump out more than goes back in — by 2040. In order to get there without massive farmland fallowing, most valley water managers have been adding as many acres of recharge ground as possible. … ” Read more from SJV Water here: Delano’s “big dig”

SGMA IN ACTION: Challenges and opportunities, Environmental justice considerations, and first lawsuits over GSP plans
Critically overdrafted groundwater basins submitted their Groundwater Sustainability Plans (GSPs) in January 2020, and high and medium priority subbasins will be submitting their GSPs in 2022. At the Environmental Law Conference at Yosemite, a panel provided an update on Sustainable Groundwater Management Act implementation, including issues being litigated in first impression lawsuits across the state. Best practices for groundwater allocation and trading, and incorporation of environmental justice concerns into GSPs. How agencies address CEQA compliance for GSA Project and Management Actions were also discussed.
Eric Averett, general manager of Roseville-Rio Bravo Water Storage District: Since 1991, Eric has been actively involved in evaluating and resolving water supply and quality challenges facing Kern County. Eric Averett serves as president of the Kern River Watershed Coalition. He sits on the board of directors for the Water Association of Kern County and the Association of California Water Agencies.
Camille Pannu, a visiting clinical law professor at the Community and Economic Development Clinic at UC Irvine School of Law: Prior to joining UC Irvine, she served as the inaugural director for the Water Justice Clinic at UC Davis School of Law, the first clinic of its kind in the country. Her practice uses administrative advocacy, strategic research, and transactional legal tools to address the impact of racial and economic inequality on access to clean, safe drinking water in California’s low-income communities.
Tom Lippe, public interest environmental law attorney: He has been actively involved since 1987 in cases dealing with land use, CEQA, NEPA, surface water, groundwater, coastal protection, and endangered species. Mr. Lippe’s practice has included many cases involving the effects of land-use changes on groundwater resources and the effects of groundwater consumption on streamflow and endangered salmonids. Mr. Lippe is currently litigating two cases challenging groundwater sustainability plans adopted under the Sustainable Groundwater Management Act for the Eastern San Joaquin and Delta-Mendota groundwater basins.

- SGMA Preparation and Stakeholder Engagement in Merced County and the Delta-Mendota Subbasin.
Each project will be presented by a current CivicSpark Fellow or Fellow Alumni.
Kamyar Guivetchi, Manager of DWR’s Division of Planning has often referred to Flood Managed Aquifer Recharge (or Flood MAR) as a “moon shot” for recharging depleted groundwater basins, but just how much Flood MAR can contribute to groundwater recharge in a watershed is unknown. However, the Department of Water Resources’ Integrated Watershed Management staff is underway with a pilot study to look at the potential for Flood MAR in the Merced River watershed.
At the October meeting of the California Water Commission, Mr. Guivetchi and David Arrate, Senior Water Resources Engineer with the Department of Water Resources, gave a presentation on the study and shared some of the preliminary results.
At the Groundwater Exchange, we’re working to update the website and adding new features.
One of those is the new Video Gallery, where you can find introductory videos on SGMA, SGMA videos in Spanish, and special topic videos on groundwater recharge, Integrated Regional Water Management, and more!
The Groundwater Exchange video gallery can link to videos posted on YouTube, Vimeo, or Facebook, so if you have a video to add, send the link to firstname.lastname@example.org.

Farmland consolidations could save water, promote solar
“Hopes are rising in the southern Central Valley that the farmland expected to be fallowed in coming years because of drought and groundwater restrictions won’t sit idle but will instead be consolidated to make room for new land uses including solar power generation. Efforts are underway locally to create a system for piecing together parcels that would allow investment at a scale large enough to support substantial photovoltaic solar arrays — or ranching or creation of natural habitat, whatever makes sense financially for landowners. … ” Read more from the Bakersfield Californian here: Farmland consolidations could save water, promote solar
Western agricultural water values diverge, with expansion in permanent and high-value crops
Westwater Research writes, “Recent trends in the Western U.S. toward high-value and capital-intensive crops that depend on irrigation are changing the importance and value of water in agriculture, and such changes have important implications for water trading and water market prices. WestWater compiled data on agricultural sales and irrigation water use to provide a unique spatial look at the value of water in agricultural use across the Western states. Please enjoy a short Water Market Insider summarizing the data on agricultural water values, and feel free to take a closer look with our online GIS story-board.”
Ridgecrest City Council, IWVGA agree on recycled water
“If an options agreement between the city council and the Indian Wells Valley Groundwater Authority comes to fruition, recycled water from the city’s wastewater facility could help balance the groundwater basin — and could potentially help Searles Valley Minerals stay in business. Sources at SVM, however, have said that while they are open to ideas “at this juncture recycled water for Searles is only a concept.” Both the council and the groundwater authorities at their respective meetings last week approved the option agreement between the two parties for recycled wastewater. … “ Read more from the Ridgecrest Independent here: Ridgecrest City Council, IWVGA agree on recycled water
