There may be many ways to feed a growing world population without losing more forests. That is the conclusion of a new study led by Karlheinz Erb, a professor at the Institute of Social Ecology at the University of Klagenfurt in Vienna. The report, which was published 19 April in the journal Nature Communications, considers a range of options for how humans will produce and consume food in 2050: from adopting low or high yield farming practices to taking up meat-heavy or vegetarian diets.
