When People Must Make Way for Nature

It is the black before dawn at the gate to the Kanha Tiger Reserve, in the highlands of central India. The still air carries a dank, penetrating chill. But it is hardly quiet. A buzzing line of tourists is forming at the ticket booth, peddlers are pouring steaming cups of tea.  Groups of green-uniformed rangers chat… read more

Photo Essay: When People Must Make Way for Nature

The forested Kanha Tiger Reserve, in the highlands of central India, is home to an abundance of rare wildlife. It also used to be home to thousands of people—that is, until they were moved out by the government to make way for endangered creatures.

Dobhas are small ponds that can help store water for use during the dry season.

In Jharkhand, Using an Old Technique for Sustainable Water

The Indian state of Jharkhand has plentiful rainfall, but most of that water runs off before it can be put to use by farmers, who struggle to make a living. To help improve irrigation and crop productivity, the Centers for International Projects Trust and Ranchi’s Birsa Agricultural University turned to a simple traditional technology, “dobhas,” small ponds that can store rainwater for months at a time.

The drillers insert the larger diameter 4" PVC pipe into the well.  Handling the 10 meter pipe is challenging.

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.

Hammering the OSL sampler, which is at the end of many auger extension rods.  The sampler fits inside the 3" PVC pipe that had been installed.

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.

Standing ankle deep in mud by the resistivity meter.  The smokestack of the brick factory can be seen in the distance.

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.

The Taj Mahal. You can see its enormous size from the line of people waiting to get inside standing on the pedestal. The line completely circled the tomb on this holiday weekend.

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 successful.
