  • India: the Impact of the 2009 Monsoon Failure

    This article is the second in a series inspired by the recent Columbia Water Center trip to India During our recent CWC trip to India (during the first three weeks of August) one news story dominated all others: this year’s near total failure of the monsoon.  Many of us in the West don’t really understand what…

  • India’s Water Future

    I recently returned from a CWC trip to India, where we have several projects underway.  During this trip, we had the opportunity to talk with a range of  water users – farmers, corporations, academic experts, and government officials.  One thing became very clear to me: Although India’s water situation is precarious, there is a real…

  • Dark Side of Solar Has Light at the End of the Tunnel

    As the United States searches for sources of alternative energy and a means to reduce its production of greenhouse gas (GHG) emissions, solar power plants have emerged as a leading candidate to address both of these problems. While these plants do indeed provide an additional means of producting energy that could potentially reduce the amount…

  • Water and Energy Conflict in Central Asia

    Water resources management in the Central Asia region faces formidable challenges. The hydrological regimes of the two major rivers in the region, the Syr Darya and the Amu Darya, are complex and vulnerable to climate change. Water diversions to agricultural, industrial and domestic users have reduced flows in downstream regions, resulting in severe ecological damages.…

  • “Ethical” Bottled Water Companies

    As much as the bottled water debate grows, it seems unlikely that any time in the near future, bottled water use will dramatically drop or stop altogether.  The convenience of it and the lack of availability of water fountains and tap water when we might need it will continue to lead us to buy that…

  • Hawaii’ s homes go Green with solar hot water heaters

    The grass may be greener in Hawaii, but now so are its houses. Solar powered hot water heaters are now replacing electric heaters that burn fossil fuels, and in the process release harmful carbon and other greenhouse gas emissions that contribute to global warming.  Hawaiian Electric Company is heavily encouraging all home owners to convert…

  • Punjab: A tale of prosperity and decline

    The state of Punjab, located in the northwest part of the country, is known as the breadbasket of India. Punjab produces 20% of the nation’s wheat, 11% of its rice, and 11% of its cotton, from only 1.5% of its geographical area.  Punjab is in trouble, however; groundwater is rapidly decreasing. Water levels have dropped…

  • Water Harvesting Making a Comeback

    In the American Southwest, water is a valuable resource that is almost always in short supply. Yet, despite the frequent discrepancy between supply and demand, homeowners and municipal managers alike  have been obligated – by law – to let the rain that runs off of their roof or falls in their jurisdiction to go its…

  • Fourth of July fireworks: water contaminants?

    Fourth of July fireworks across the United States are definitely a long tradition that millions of people eagerly wait and enjoy. The concern is that fireworks traditionally have included potassium perchlorate as the oxidizer, a material that provides the oxygen that fireworks need to burn and that perchlorate is an environmental pollutant with potential adverse…
