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. 🔗 https://t.co/MWmjtPzy9k

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

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. https://t.co/B1NpHNcblY

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. 🔗 https://t.co/B1NpHNcblY

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. https://t.co/bAo8fGjBcx

Imagine your city slowly sinking. In India’s megacities, 80M+ people face this reality. New satellite radar research by @nitheshnirmal reveals where the ground is shifting unevenly. 🌍🏠 #LandSubsidence #GroundwaterUse

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
