    Tensiometers in Punjab

    So far, tensiometers have been tested in four central districts of Punjab, initially with more than 500 farmers the first year, and then peaking with an additional 4,500 farmers in 2011 before testing was scaled back. Data showed, on average, a 30 percent reduction in the water used in the test plots when compared with…

    Achieving Sustainable Water, Energy and Agriculture in Gujarat, India

    Watch a video about the Columbia Water Center’s project to address a looming water crisis in north Gujarat, India.

  • Sampling The Ganges

    Sampling The Ganges

    For the final part of my journey, we will be visiting numerous sites, mainly on the main rivers of Bangladesh. The samples and field data will ground truth and calibrate satellite data improving our analyses. We first stopped at an area that had converted from shrimp farming to rice, then spent two days on the…

    Aquanauts Take on New York Water Issues

    Working with engineering PhD candidate Rob Elliott, we imagined a green roof and blue roof system that would serve as a space for environmental education and student wellness, the culmination of a semester spent examining and taking action on stormwater management issues in New York City.

    Improving the Water Outlook in the Himalayas

    Andrew Robertson, a climate scientist at the International Research Institute for Climate and Society, discusses his research on helping reservoir managers in northern India make better planning decisions by improving their ability to predict how climate change will influence water availability.

    Hiron Point in Sundarban

    We traveled by boat to the south part of the Sundarbans near the Indian Ocean to install a GPS at Hiron Point, this isolated facility also hosts a tide gauge recording long-term water level changes due to rising sea level and land subsidence. Our GPS will help distinguish how much of each there is in…

    Epic Wetness in Greater NYC, and What Broadleaf Trees Have to Say About It

    2012 is turning out to be an exceptional year in the eastern US. Starting out with what was essentially a #YearWithoutaWinter, followed by a heat wave in March, a hot summer, Macoun and Cortland apples coming in 2-3 weeks early, and the continuation of a severe drought in the Southern US that expanded into the Midwest…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
