PlacerSustain: Voices of Placer County's Sustainability Community

Recent trainings in Senegal have improved trust between farmers and researchers, leading to increased use of climate forecasts and other information.

A new report by the Columbia Water Center, produced in conjunction with Veolia Water and Growing Blue, could help expose the real nature of water risk in urban and rural areas throughout the country--even in places that most people think of as having plenty of water.

Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements that characterize the ice and the organisms living inside it. Some [...]

On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light. These organisms are not frozen into the ice; [...]

The Earth Institute is pleased to welcome National Grid into the Corporate Circle, a collective partnership of leading corporations from across the globe committed to pursuing sustainable development objectives. Through a generous gift, National Grid will support sustainable energy research at the Earth Institute.

Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works. Spring on Alaska’s North Slope provides an especially productive environment for fieldwork. When the sun never sets, it’s easy to linger in the field and the lab long into the well-lit night. Our team spent about six [...]

Roads data is critical to planning and development of rural transportation in developing countries, where better transportation systems can help improve livelihoods.

Renowned collector and Wall Street money manager William H. Gross sold pieces from his unparalleled U.S. stamp collection for the first time at an auction at the Robert A. Siegel Auction Galleries here in New York on April 9. Since 2008, Bill and his wife Sue have donated over $19 million to the Millennium Villages project, and they continued their generosity by donating the proceeds from the auction to the Earth Institute and to Doctors Without Borders.

The Earth Institute’s Haiti Research and Policy Program at the Center on Globalization and Sustainable Development welcomed two distinguished speakers as part of the Spring 2013 Haiti Dialogue Series to discuss government capacity building and national monitoring systems for government funded programs.

Being able to model solutions visually is a critical component for managers’ intent for solving environmental problems. For that reason, perhaps, advancing the way we design the built environment has always been my keenest interest. Sustainable design requires more than just the ability to create spatially: it requires expansive considerations—materials, energy, water-use, financial feasibility, new technologies. It must successfully execute the maxim “form meets function”.

While I arrived in Barrow, Alaska on Tuesday, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack, and graduate student Kyle Kinzler from Arizona State University, got here one week ago. They took a few days to unpack and set up their lab (everything they need to work here must be shipped to Barrow in [...]

Of non-Arctic states, China has shown the most interest in the Arctic as climate change opens up the region to new economic development. The ways in which China attempts to balance its economic interests and environmental responsibilities within its energy policy may provide a predictor of its future behavior in the Arctic.

Last October, Superstorm Sandy provoked widespread frustration and fear after it left more than 7.5 million people in the New York Metro area without power. In the hardest hit areas, outages lasted two weeks or more. These failures led many observers to wonder if America’s aging electrical grid was up to dealing with emerging climate and other challenges.

When the Environmental Defense Fund asked me to measure how biogas cook stoves were changing the lives of farmers in rural India, there wasn’t a word in that question with which I was comfortable. Having just graduated from the Undergraduate Program in Sustainable Development, I had never done fieldwork; and the concept of a biogas digester, which turns cow dung into natural gas through anaerobic digestion, was itself a mystery. I had no idea that this was the beginning of a steep learning curve into low-carbon development at a large scale. But even more, that it would provide a window into the lives of families whose existences have permanently improved thanks to the clean cooking stoves.

In a career that has already spanned the roles of farmer and corporate sustainability professional with ARAMARK; current MPA in Environmental Science and Policy (MPA-ESP) student Kendall Singleton knows that her niche in the sustainability sector lies in designing and implementing sustainable food systems. As her time in the MPA-ESP program comes to a close, Kendall will apply her project management experience and her quantitative and analytical skills to whatever role lies in store.

Andy Juhl and Craig Aumack, microbiologists from Columbia University’s Lamont-Doherty Earth Observatory, are spending a month in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms. They’re investigating the factors that control the growth of algae inside of sea ice, how these algal communities are [...]

The Lamont Icepod team is a blended mix of engineers and scientists learning from each other through the design and testing of this new instrument. With a range of talents and backgrounds, the project mixes seasoned field workers with those new to field work; experienced instrument developers with those newly learning this end of engineering; and scientists with countless hours spent pouring over Greenland ice sheet data with those exploring the ice sheet for the first time. It is the opportunity for mentoring and development that comes from this mix that has made the Icepod Instrument Development Project a good fit for its American Recovery and Reinvestment Act funding.

Eight hundred years ago, relatively small armies of mounted warriors suddenly exploded outward from the cold, arid high-elevation grasslands of Mongolia and reshaped world geography, culture and history in ways that still resound today. How did they do it?

This week in PLoS One, a group of researchers coordinated by the International Union for Conservation of Nature (IUCN), published a new framework for assessing threats to ecosystems. This study offers the theoretical foundation for the Red List criteria for ecosystems, which like its predecessor, the Species Red List, will aim to inform government and society about the current status of biodiversity and provide the data necessary to develop strategies and priorities for conservation.
