*** Policy Implication of Research ***
Recently, Nithesh (@nitheshnirmal), one of our PhD students, published a groundbreaking paper on #sinking#Indian#megacities in @naturesustainab . Citing this study, #NationalGreenTribunal—India’s quasi-judicial authority responsible for enforcing environmental laws—has issued a #nationwide directive to develop #LandSubsidence hazard maps for major Indian cities. I am pleased to see how quickly this research has been translated into policy. Well-done Nithesh!

India’s major cities are sinking — and infrastructure is at risk.
A Nature Communications study by UNU-INWEH’s Manoochehr Shirzaei & colleagues identifies where building damage is most likely to occur.

*** Media Coverage ***
here is an excellent report on our recent paper on #indian#megacities#subsidence led by PHD student Nithesh (@nitheshnirmal ) published in @Nature Sustainability.
The report not only discusses the problem but also mentions some of the possible solutions, mainly, #Managed #Aquifer #Recharge.

New results: the 2020–2022 drought led to ~3 km³/yr water loss at Lake Mead, incl. groundwater. Remote sensing data show up to 8 mm/yr uplift as the crust rebounds. Drought impacts reach far below the surface. https://t.co/8S8BGP1Tag
#Drought#Groundwater#InSAR#WaterManagement
Using satellite radar data (InSAR), new research by UNUINWEH scientist & colleagues identifies land subsidence hotspots across five Indian cities — linked to groundwater overexploitation.
Findings highlight the need for sustainable groundwater management.

Congratulations to Susanna Werth (@HIRSLab) and Manoochehr Shirzaei (@shirzaei) on this important work on cities sinking in India. @vtgeosciences@VT_Science https://t.co/0E18e9BcIL
Groundwater decline is making India’s cities sink.
A new study by UNU-INWEH scientist & and colleagues finds that over 2,400 buildings in New Delhi, Mumbai & Chennai face high damage risk — rising to 23,000+ across five megacities if trends continue.

Sinking land is quietly destabilizing urban infrastructure in India’s largest cities, putting thousands of buildings and millions of people at risk, according to #VirginiaTech scientists.

Congratulations, Prof. Sonam Futi Sherpa, for this excellent and important work on the influence of changes in precipitation dynamics in the Himalaya on glacier melting! It was a pleasure working together on this. #GRACEFO#GRACEsatellite
I am excited to announce the publication of our manuscript entitled "Investigating the influence of climate seasonality on glacier mass changes in HMA via GRACE observations" on IEEE JSTARS with @HIRSlab. Here is a link publication: https://t.co/MVcMF40UMZ #GRACESatellite
**** NEW PAPER ALERT ****
Just published in @Nature Cities, led by Dr. Ohenhen (@Leonardgeol) and in collaboration with two generations of researchers from @EOI_lab and @HIRSlab of @VT_Science, we map #sinkingland at 28 major #US cities. The results are eye-opening and concerning, but there is time to act! Congratulations, Leonard and team!

The HIRS and EOI labs got DoD funding to study vertical land motions in Alaska. We will investigate their interactions with the water cycle in permafrost regions. Read the story at VT News: https://t.co/C2GIChw7kC
