    Last Sample and Home

    We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.

    OSL Samples at Last

    The success of the tube wells for drilling and obtaining samples was a great boon to our field program. We drilled three additional tube wells to complete a five-well transect across the abandoned river valley. When we date the samples, we will find out if the river switched position suddenly, possibly from an earthquake.

  • Sustainability Requires Technology, Ethics and Political Will

    What we are missing here in the United States is the environmental leadership that we had during the 1970s and 1980s when we showed the world how to grow an economy while building our knowledge of ecosystems and reducing the degree of damage we were inflicting on the natural world.

    Tubewells to the Rescue

    The resistivity testing was hampered by bad roads and flooded fields. The augering was proving similarly difficult in the thick muds of the abandoned channel. It was time to change to our alternative plan: drilling with tube wells. That worked better and we had turned a corner.

    Heading out to our field area, we discovered that the abandoned river valley we planned to study was completely flooded. There was pani—the Bangla word for water—everywhere.

    Bangladesh and India, Too

    Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very…

  • Sustainability Has Entered the Political Mainstream

    Environmental protection and economic development have been integrated into the single overarching idea of “sustainability.” These are centrist public policy positions in the mainstream of politics here in New York State.
