Drinking water near coasts is under threat worldwide: A recent study shows how the salinization of groundwater due to over-abstraction and rising sea levels is becoming a global problem 👉 https://press.uni-mainz.de/drinking-water-near-coasts-is-under-threat-worldwide/
A More Troubling Picture of Sea Level Rise Is Coming into View
Scientists have uncovered a “blind spot” in the research on rising seas, revealing that tens of millions of people thought safe from coastal flooding are at risk of inundation. Across much of the world, sea levels are higher than previously assumed and land is sinking faster.

Excerpt: "The other new study focused on the world’s #RiverDeltas. It has long been known that many #deltas are sinking under the influence of #Groundwater pumping. But as Robert Nicholls, climate adaptation researcher at the University of East Anglia, notes, 'There have been lots of different estimates.' Data were inconsistent and based on crude, delta-wide estimates. 'Now at last we have a consistent data set, with high spatial resolution.'
"That data comes from Leonard Ohenhen, an earth system scientist at the University of California, Irvine, who used satellite-mounted radar to produce 3D maps of subsidence on 40 of the world’s biggest and most populous river deltas. He has found that subsidence afflicts more than half those deltas. Most startlingly, in 18 cases subsidence rates exceed those of #RisingTides — hence, more than doubling the effective yearly rise in local sea levels, and in some cases multiplying it tenfold.
"This again puts tens of millions of people once thought safe from rising tides this century in imminent harm’s way, including those living on the deltas of the #Nile in #Egypt, the #Mekong in #Vietnam, the #Mahanadi in #India, and the #YellowRiver in #China. If the current rate of subsidence persists, these areas will be flooded much sooner than thought.
"Researchers say many deltas and other low-lying coastal areas not included in the two studies are at greater risk than believed and urgently require detailed investigation of both actual sea levels and the rate of land subsidence."

"Water Crisis Beneath Our Feet"
America’s water crisis isn’t just in rivers and reservoirs—it’s underground.
Aquifers are being drained faster than they can recover, farmland is at risk, and entire communities could face dry wells.
This is the hidden emergency no one is talking about.

That's interesting.
More groundwater is formed under beech forests than under pine forests. This has been shown by scientists at the Thünen Institute for Forest Ecosystems. This finding is important for drinking water supply and forest conversion in Germany.
Perhaps it's relevant for your country too.

Low Snow Reserves – again.
Switzerland heads into spring with 30–60 % of normal snowpack. Less melt = less groundwater recharge. Rain gauges won't show you what's underground. Direct measurement will.

Over on LinkedIn, my colleague Prof. Wendy Timms has a nice video of her on groundwater recharge fieldwork in the lava caves at Byaduk. Check it out!
Come underground in this rough cut quick video from the past few days (and earlier)! We are exploring the relationship between each rainfall event and water underground - led by Prof Andy Baker FRSN FAGU with a wide research team. The Australian Research Council funded setup of this National Observatory*. Shout out to local helpers including catchment managers, geotech engineers and gold geologists, my family, and students and uni staff who have ventured into our underground spaces in mines, tunnels and caves for this valuable data (2022-to date). It's a followup to an IAH2025 presentation* on implications of record low soil moisture deficits across parts of Australia for water availability in catchments and basaltic aquifers and associated reports on drip seepage in local mines. Now back to the computer and catching up on desk work.... *The IAH presentation is here with links to download several journal papers and articles: https://lnkd.in/geCsZSji
