Water Matters, the blog of the Columbia Water Center, focuses on the assessment, understanding and resolution of the potentially global crisis of freshwater scarcity.
We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.
We switched to a towed electromagnetic system to image the fresh and saline groundwater in Bangladesh, and ran into a variety of problems, including high winds, strong currents and running aground.
Continuing our electromagnetic survey of fresh and saline groundwater, we saw the landscape change from lush watermelon fields to fallow rice fields as the salinity increased towards the sea.
We continued our electromagnetic expedition to image fresh and saline groundwater into the Sundarbans Mangrove Forest, the world’s largest. While guards protected us from tigers, it was a wild boar that dug up some of our equipment.
I am back in Bangladesh to explore the distribution of fresh and saline groundwater in the coastal zone, needed for drinking in the dry season.
Earth Institute researchers are in the field studying the dynamics of the planet on every continent and every ocean. Here is a list of projects.
In the fall 2020 course, “Responsiveness and Resilience in the Built Environment,” students learned about sustainability challenges in three urban areas and came up with potential solutions.
Climate change disrupts the water cycle in ways that could profoundly alter how we live our lives.
An uptick in mining-related tragedies in Brazil points to the need for stronger regulations.
