    Keeping our Freshwater Fresh: Ecosystem Management Tools

    We have been harming our hard-earned water resources; is it too late to clean up our act? With the help of the nine principles of ecology we can work towards effectively and sustainably managing these ecosystems, which will help us preserve the quality of New York’s freshwater resources and maintain our high quality drinking water.

  • Coastal Erosion and Adaptation to Climate Change

    Coastal Erosion and Adaptation to Climate Change

    Increasing understanding of the extent of coastal erosion and its interaction with other naturally existing geographical features such as mangrove vegetation is one of the areas of research that may help reduce vulnerability of small-island developing states to climate hazards.

    New Predictions of Climate Change’s Impact on Agriculture

    Developing countries are more likely to see a drop in agricultural productivity and increased food prices due to climate change, particularly in tropical regions, according to a set of new studies out this week.

    Map Your Food

    Where does London get its fruit? Where are the “food swamps” in Los Angeles? Where do tomatoes from Spain wind up? Where are the composters in New York City? For lovers of geography, and of the sociology of food, “Food: an atlas” offers lots of informative and curious distraction.

  • Climate Change and the Future of Mono Lake

    Climate Change and the Future of Mono Lake

    Understanding the climate history of Mono Lake will help scientists understand the future impact of climate change. This is no esoteric question for Los Angeles, which depends in part on Mono Lake’s watershed for drinking water, green lawns, agriculture and industry.

    IRI@AGU: Schedule of Events + Q&As

    Four scientists and one PhD student from the International Research Institute for Climate and Society are attending the 2013 American Geophysical Union’s Fall Meeting. Below are links to Q&As with each of the presenters and the schedule of their posters and presentations.

    Is Sustainability Sustainable in a Post-Bloomberg NYC?

    With the end of Mayor Michael Bloomberg’s tenure drawing near, many are speculating which of his policies will survive the next administration. New York City’s comprehensive environmental plan, PlaNYC 2030: A Greener, Greater New York, has been championed politically by Bloomberg, but is grounded in science and data, and performance management. It has demonstrated progress,…

    When the Sahara Turned to Sand

    The Sahara wasn’t always a desert. Trees and grasslands dominated the landscape from roughly 10,000 to 5,000 years ago. Then, abruptly, the climate changed. A study by Lamont-Doherty’s Peter deMenocal says it took just a few hundred years to happen.

    Just How Effective is Green Infrastructure?

    Over the next 18 years, New York City’s 2010 Green Infrastructure Plan will spend $2.4 billion on green infrastructure— green roofs, tree plantings, and increased vegetation— to combat coastal pollution. But how does green infrastructure work and how effective is it really?
