Five-point Plan Proposed
To Feed World in a Sustainable Fashion
An international team of scientists has unveiled a plan that they say would double food production by 2050
while reducing the global environmental impact of agriculture
. Reporting in the journal Nature
, scientists from the U.S., Canada, Sweden, and Germany said that the only way the world community
could sustainably feed the estimated 9 billion to 10 billion people expected on the planet later this century would be by taking the five following steps: halt expansion of farmland into tropical forests and wild lands; more efficiently use large swaths of underutilized farmland in Africa, Latin America, and Eastern Europe, boosting current food production by nearly 60 percent; make more efficient use of water, fertilizers, and chemicals, which are currently overutilized in some areas and underutilized in others; shift diets, especially in the developed world, from excessive meat consumption; and reduce the amount of food that is discarded, spoiled, or eaten by pests, which currently amounts to about a third of the food supply. “For the first time we have shown that it is possible to both feed a hungry world and protect a threatened planet,” said Jonathan Foley
, head of the University of Minnesota’s Institute on the Environment and lead author of the study.
