After finally reaching the Mongla and our boat, we settled into our new home. It is a similar design, but much larger than the one we used in September. As we ate dinner and explored the ship, it started the overnight journey to the southeastern part of the Sundarbans where the wildlife is most plentiful. [...]
Over the past decade, average global food prices have more than doubled, with 2008 and 2010 seeing excruciating price spikes that each had far-reaching economic, geopolitical and social consequences.
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?
To help my students in a class on hazards of Bangladesh better understand the country, I am taking them there to experience Bangladesh for themselves.
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 if it meant promoting growing practices that would ultimately prove unsustainable.
Increased growing-season heat due to climate change in coming decades could push staple U.S. crops off a cliff, and cause world food prices to jump, a Columbia University economist told a press briefing at a top scientific meeting this week. In a panel organized by the American Association for the Advancement of Science, economist Wolfram [...]
The United States and five other countries agreed this week to fund an effort to cut emissions of methane, soot and other pollutants to start to slow the rate of human-induced climate change.
Scientists at Columbia University’s Earth Institute will present important new work on global climate, air pollution, agriculture and other issues at the Feb. 16-20 meeting of the American Association for the Advancement of Science, in Vancouver, B.C. Click hyperlinks for scientist contacts and other information. Background materials will be posted just before the meeting at [...]
A talk Monday by Cynthia Rosenzweig of the Center for Climate Systems Research serves as a good example of how some of the hard science being discussed at the American Geophysical Union’s fall meeting intersects directly with human welfare. She outlined the progress of a new global project that will help scientists produce more accurate forecasts of the effects of climate change on food supplies.
The last major drought to hit the northeastern U.S. lasted three years and shrunk New York City’s reservoirs by nearly three quarters. But as bad as that drought was, the region has seen at least three dry spells in the last 6,000 years that were far worse, says Dorothy Peteet, a climate scientist at Columbia University’s Lamont-Doherty Earth Observatory. Peteet presented new results from her Hudson River work Monday at a press conference at the AGU’s fall meeting in San Francisco.
