One Half of World’s Population Could Face Climate-Induced Food Crisis by 2100

A rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave one half of the world’s population facing serious food shortages, new research published in Science shows.

To compound matters, the population of this equatorial belt—from about 35 degrees north latitude to 35 degrees south latitude—is among the poorest on Earth and is growing faster than anywhere else.

“The stresses on global food production from temperature alone are going to be huge, and that doesn’t take into account water supplies stressed by the higher temperatures,” says David Battisti, PhD, a University of Washington atmospheric sciences professor.

“This is a compelling reason for us to invest in adaptation because it is clear that this is the direction we are going in terms of temperature, and it will take decades to develop new food crop varieties that can better withstand a warmer climate,” says Rosamond Naylor, PhD, director of Stanford University’s Program on Food Security and the Environment. “We are taking the worst of what we’ve seen historically and saying that in the future, it is going to be a lot worse unless there is some kind of adaptation.”


Field Notes

Researchers Find Convincing Evidence of Probiotics’ Effectiveness

Up to one in five people taking antibiotics stop their therapy due to diarrhea. Physicians could help patients avoid this problem by prescribing probiotics, according to a study by researchers at Albert Einstein College of Medicine of Yeshiva University published in American Family Physician.

Antibiotics target “bad” bacteria but may also kill the “good” bacteria in the large intestine, leading to diarrhea. Diarrhea can also result from bacterial and viral infections. Probiotics have been promoted as restoring the microbial balance disrupted by antibiotics and infections. Probiotic bacterial strains are added to certain yogurts and brands of miso and other fermented foods and are also available as powders and pills sold in health food stores.

The Einstein scientists reviewed the medical literature and found seven high-quality studies in which probiotics were administered. The researchers concluded that the studies support the use of probiotics for avoiding diarrhea resulting from antibiotic use or gastrointestinal viral or bacterial infections. In addition, the probiotics used in these studies were found to rarely cause adverse effects, even in children.
