Plastic microbeads, common in soap, toothpaste and other consumer products, are flooding waters. A team from Lamont-Doherty Earth Observatory is doing the first large-scale assessment of their impact on New York’s waterways.
Water Matters, the blog of the Columbia Water Center, focuses on the assessment, understanding and resolution of the potentially global crisis of freshwater scarcity.
On March 2, 2017, Tanzania banned all exports of unprocessed gold and copper concentrates. The measure was taken in order to force companies to set up in-country processing of raw materials, with hopes of fostering the development of a smelter in the country.
Richard Seager and Park Williams, climate scientists at Lamont-Doherty Earth Observatory, discuss how water will be affected by warmer temperatures, and how their research increases understanding of these issues.
Alan Burchell is the founder and principal of Urbanstrong, which he started shortly after graduating from Columbia’s Master of Science in Sustainability Management program in 2014. When choosing courses, Alan encourages MSSM students to fill up their tool belts. In his experience, “Knowledge is great, but tools get you hired.” Alan recommends to take classes that will teach you a transferable skill.
Columbia Water Center experts argue that dam infrastructure issues must be connected to a broader conversation about America’s water resources.
A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.
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.
Overall global losses from natural disasters such as floods, landslides or earthquakes amount to about $300 billion annually. A rapid and early response is key to immediately address the loss of human life, property, infrastructure and business activity.
Glaciers around the world have retreated at unprecedented rates and some have disappeared altogether. The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.
For Mexico City’s biggest businesses and its poorest neighborhoods, rainwater harvesting could help address an enormous water crisis plaguing the city, a recent Columbia Water Center study found.
