Getting the Tools to Get Hired

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.

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.

Severe flooding occurred during the 2011 monsoon season in Thailand, resulting in more than 800 deaths and 14 million people affected, mostly in the northern region and the greater Bangkok metro area.

Project Uses Satellites for Rapid Assessment of Flood Response Costs

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.

The Glaciers Are Going

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.

Michelle Ho: In a Land of Plenty, Big Water Problems

Michelle Ho grew up in Australia, the driest inhabited continent, with an appreciation for the value of having a clean glass of water to drink. Now, she conducts research for the Columbia Water Center on America’s water systems.

An Ancient Tool Holds Promise for Modern Water Problems

The potential effectiveness of harvesting rainwater to bolster water supply and reduce potentially polluting runoff varies greatly from place to place, even within a particular city or neighborhood. Now researchers at the Columbia Water Center have developed a tool to assess the potential of rainwater harvesting throughout the United States.
