    Facing the Food and Water Challenges of the Future

    The global population, now 7 billion, is expected to reach 9 billion by 2050 and will require 70 percent more food than we are producing today, and much more water for agriculture, drinking and industry. Will we have enough water to meet the demand?

  • The Groundwater Crisis and the “Grass that Grows in the Water”

    The Groundwater Crisis and the “Grass that Grows in the Water”

    Rice is the world’s third-largest crop after wheat and corn; by some estimates it accounts for fully one-fifth of the total calories consumed by the human race. Given these facts, it’s not surprising that countries that have historically struggled with devastating famine would do whatever it takes to ensure strong production of the grain, even…

    One Planet, Too Many People?

    Can we manage the needs of 9 billion people for water, food and energy without depleting our resources and ruining the environment? “The solutions,” says Tim Fox, “are all within the capability of existing technology.”

    China’s South-North Water Transfer Project: A Means to a Political End

    In order to maintain the status quo, let alone to grow, cities like Beijing, Tianjin, Shijiazhuang and Zhengzhou need more water. But the South-North Water Transfer Project–which when completed will transfer 174 times more water per year than the city of Los Angeles receives from various diversions of the Colorado River– is putting in place…

  • A Changing Climate for Small Island States

    A Changing Climate for Small Island States

    Small island states are uniquely vulnerable to climate change because of their geography and socioeconomic characteristics. As the physical impacts of climate change interact with social and economic vulnerabilities, climate change poses a significant threat to the islands’ physical, social, and economic well-being.

    Earth Institute Science in Spotlight

    Research presented by Earth Institute scientists at the 2011 American Geophysical Union fall conference generated a lot of attention from the media. Much of it came from a press conference held to discuss findings by Steve Goldstein from the Lamont-Doherty Earth Observatory and his colleagues on the potential for future drying up of the Dead…

    Under the Dead Sea, Warnings on Climate and Earthquakes

          An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period analogous to scenarios for climate change in coming decades. With nations in the volatile region already running short on water, the finding could be a…

    Unsettled by Climate Change

    Climate change already laps at the edges of some communities, disrupting local economies and habitat, and forcing resettlement. But a new study notes that any efforts to offset the effects of shifting climate could lead to even more displacement and disruption for many people, particularly the poor.

    7 Billion on 10/31: The Numbers Can Be Scary

    You can now watch the tape of “The World at 7 Billion: Sustaining Our Future,” the Earth Institute’s panel discussion held at Columbia Oct. 17 and featuring the presentation by Professor Joel E. Cohen on the “good and bad news” behind the growing world population.
