Chris and Dan discussing notes on locations to visit based on recent satellite images and entering them into the GPS.

Sampling on the Ganges and Brahmaputra Rivers

The final phase of our revolves around visiting chars, sandy river islands, on the Ganges and Brahmaputra River. Chris and Dan are making measurements of soil salinity and moisture and spectra of the soil reflectance, while Liz and I collected samples for OSL dating and understanding the OSL properties of the river sediments here. This entails a mixture of driving around the country and spending time on small country boats and walking around the chars.

2015 Indonesia Fires Killed 100,000 People, Says Study

In fall 2015, smoke from agricultural fires in Indonesia blanketed much of equatorial Asia. Schools and businesses closed, planes were grounded and tens of thousands of people sought treatment for respiratory illnesses. In a new study, researchers estimate that the smoke caused upward of 100,000 deaths across Indonesia, Malaysia, and Singapore.

Global Philanthropy and Inequality

Recent trends now point towards global philanthropy becoming the new norm. Global philanthropy aims to reduce inequality in developing countries through many forms. But inequities persist, and different manifestations of global philanthropy will be challenged to increase impact and achieve a demonstrable shift in areas such as poverty, health, access to opportunity, and beyond.

Report Charges ‘Nepotism and Neglect’ on Bangladesh Arsenic Poisoning

Two decades after arsenic was found to be contaminating drinking water across Bangladesh, tens of millions of people are still exposed to the deadly chemical. Now a new report from the group Human Rights Watch charges that the Bangladesh government “is failing to adequately respond” to the issue, and that political favoritism and neglect have corrupted the government’s efforts.

Does Pollution Regulation Kill Jobs? Lessons for China from the U.S.

The problem of air pollution in China continues to reach new heights. To combat the problem in any real way stringent regulation is needed. A new paper from Columbia University’s Earth Institute finds that this can be done without hurting job creation.

The Changing Face of Air Quality

Looking at regional differences in PM2.5 concentrations gives us a sense of the changing face of air quality throughout the world.

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.
