  • What is “it” about bottled water?

    Recently, in a discussion about bottled water, my colleague stated, “I’ve heard this argument before – it’s the bottle, not the water, that’s the problem.  Would these people be happier if the bottle was made from recycled glass?”   As one of “these people” who are troubled by bottled water (and in spite of the disparaging remark,…

  • CWC’s new Great Lakes Column

      The Columbia Water Center is leading intellectual inquiry into the assessment, prediction and solution of the growing scarcity of fresh water. Although the CWC is looking at water issues across the globe, up until now, little attention at the Center has been focused on the Great Lakes. Some past student projects have explored in-depth…

  • Seawater desalination: the solution?

    Water is an increasingly scarce commodity in many parts of the world, and it seems seawater desalination is one of very attractive solutions available to these regions. Of all the Earth’s water, 94 percent is saltwater from the oceans and only 6% is fresh. If plenty and easily accessible seawater could turn into fresh drinking…

  • Dam Break in Northeast Brazil: Can We Blame Global Warming?

    Nordeste, the driest region in Brazil, has been castigated by heavy rainfall in the last two months. Yesterday a dam broke in the state of Piaui killing at least four people. The video below shows a partial bridge that collapsed after the dam break. The media shows every day more and more news about natural…

  • A Cistern in NYC – Yes!

    A cistern is not what you would expect to find in a NYC house; however, a brownstone in our backyard has its own rainwater collection cistern. The brownstone, billed as the “Greenest House in NYC” and the first residential property in Manhattan to receive the coveted LEED certification, was recently highlighted in Good Housekeeping Magazine.…

  • Water Sensors – Saving Water in Irrigation

    One of the largest uses of fresh water withdrawals in the United States is for irrigation. The USGS estimates that 60% of the worlds fresh water withdrawals is for irrigation purposes, which calculates to 137,000 million gallons per day used for irrigation purposes.  Some of this water is for irrigation of crops, while other of…

  • Is Water Too Cheap in China?

    The Chinese capital of Beijing will raise water prices this year as an attempt to conserve its scarce water supply. Cheng Jing, the head of Beijing’s water-resources bureau, announced on May 10th the city would raise water prices within the next two months. This price hike will be the fifth one since 2001 in a bid to promote conservation.

  • “The Truth About Water Wars”

    We’ve all heard about the horrors of the genocide in Darfur, followed Nicholas Kristof’s evangelical Op-Eds, and seen the benefit concerts to raise money towards the cause. Perhaps some know too of the ethnic differences tinting much of the clash, know the history of relations between the Sudanese government and the Sudan Liberation Movement/Army.  But few…

  • Green Infrastructure

    Since May is American Wetlands Month, I want to highlight the use of constructed wetlands, or green infrastructure, as a way to manage or restore natural hydrologies to an ecosystem. The technologies mentioned below are not necessarily new or revolutionary. However, with the recent government emphasis on infrastructure and green projects, I think the scale…
