  • Cascading impacts of groundwater input to coral reefs

    Groundwater input to coral reefs directly affects water chemistry and triggers a cascade of changes in the coastal ecosystem, according to a new study led by University of Hawaiʻi (UH) at Mānoa oceanographers. Freshwater from land that flows into the ocean beneath the sea surface, termed submarine groundwater discharge, was... read more...

  • Pourquoi France Télévisions se lance-t-elle dans une météo de l’eau ?

    Le Journal Météo Climat explique pourquoi tenir le bulletin de l’état des nappes phréatiques en France est devenu une nécessité. C’est l’objet de la nouvelle météo de l’eau qui arrive à l’antenne ce 20 juin sur France Télévisions.

  • Cambodia moves to groundwater regulation amid rising water security concerns

    As over half the population depends on groundwater during the dry season, experts and stakeholders at a national dialogue pushed for urgent regulatory action and policy to manage over-extraction, climate stress and fragmented data, which could pose serious challenges to the country’s water security in the future. Find out more... read more...

  • How groundwater pumping is causing cities to sink at ‘worrying speed’

    Many factors can contribute to subsidence, including building, mining, tectonic shifts, earthquakes, and natural soil consolidation, where soil is pressed closer and becomes more dense over time. But “one of the most common causes is groundwater extraction and dozens of coastal regions and cities are sinking at a worrying speed,... read more...

  • Earth’s mantle gases found seeping into groundwater far from volcanic zones

    New research has uncovered new evidence to suggest that Earth is leaking gases from deep inside its mantle, even in regions without any volcanic activity. The study reveals that gases including helium and argon are slowly seeping hundreds of kilometres up through Earth’s crust. The highest amount of gas was... read more...

  • That sinking feeling: Australia’s Limestone Coast is drying up

    The gin-clear waters of the Kilsby sinkhole, a popular freshwater diving site, provide visibility of up to 65 metres. But water levels have dropped 1.5 metres between January and March 2025. It’s a long-term decline: the vast groundwater network in the limestone crust that straddles the border between South Australia... read more...

  • Landmark mine water heat scheme goes live in Wales

    Previously untapped heat from a mine water treatment scheme in Wales is now being harnessed to provide low-carbon heating. The mine water is naturally warm due to geothermal energy from the earth’s crust and heat retained from its time circulating through underground rock layers and former coal mines. An innovative... read more...

  • Bengaluru – Scientists raise alarm as rural water supply goes from depths to debt

    The city of Bengaluru and its surrounding peri-urban areas have been grappling with severe groundwater depletion, driven primarily by over-extraction. The administrative focus remains largely on technical and financial fixes — laying pipelines, ensuring capital investment. Researchers argue that more emphasis needs to be placed on effective water resource management.... read more...

  • Why is land in South Africa rising? Droughts may have a role to play

    Land in South Africa has been rising at the rate of 2 millimetres per year, according to a recent report, thought to be due to hot magma rising from the Earth’s mantle. But, loss of water during droughts may have caused the earth’s surface to bounce up as an elastic... read more...

  • Depleting groundwater in Pakistan

    Pakistan’s agriculture sector is becoming increasingly dependent on groundwater due to multiple factors, including declining river flows, erratic rainfall, expansion of water-intensive rice and sugarcane crops, increased cropping intensity, and more recently, the widespread adoption of solar-powered tubewells that offer minimal operating costs, which encourages indiscriminate pumping of groundwater. But... read more...
