Overall, the event underscored how governments and health authorities in many developing countries face the dilemma of how to feed their growing population while ensuring their food is nutritious and discussed relevant strategies to transform nutrition security challenges into opportunities. As rice prices increase, relative to nutrient-rich foods, people will diversify their diets away from rice.
Worldwide, insect pests consume up to 20 percent of the plants that humans grow for food, and that amount will increase as global warming makes bugs hungrier, according to a study published Thursday in the journal Science.That could encourage farmers to use more pesticides, which could cause further environmental harm, scientists said.For every degree Celsius (two degrees Fahrenheit) that temperatures rise above the global historical average, the amount of wheat, corn, and rice lost to insects will increase by 10 to 25 percent, the study says.
Bad news is, the solar shading that would come with geoengineering would negatively affect crops, likely wiping out the gains from lower temperatures.“If we imagine geoengineering as an experimental surgery, our findings suggest that the damages or side effects from the surgery are just as bad as the original disease,” says UC Berkeley agricultural economist Jonathan Proctor, lead author of the new study.A funny thing happens to light when it hits a volcano’s sulfate aerosols in the air.
“Presumably, agricultural systems have been motivated by the need to feed more people and to remain profitable,” says Davis, “and this suggests that environmental impacts of food production – like water use for irrigation – only receive secondary consideration in a farmer’s decision of what crop to plant.
