    Water Security: Finding Solutions for a World at Risk

    “This is a mess, and it is a mess that we have not attended to yet,” Earth Institute Director Jeffrey Sachs said at a conference on water security held today at Columbia University. “Humanity is the driver, but we don’t have our hands on the steering wheel very much.”

  • Columbia University to Monitor NYC Waterways

    Dr. Wade McGillis of Columbia University’s Lamont Doherty Earth Observatory is the Lead Principal Investigator on a new project entitled “NYC Sustainable Urban Water Quality: the Earthwatch Institute Freshwater Program”, set to take place through January 2017. Dr. McGillis and his staff will be working in partnership with the Earth Watch Institute to deliver this…

    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…

    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…

    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…
