Can we feed 10 billion people on organic farming alone?
Organic farming can help to both feed the world and preserve wildland. In a study published this year, researchers modeled 500 food production scenarios to see if we can feed an estimated world population of 9.6 billion people in 2050 without expanding the area of farmland we already use.
They found that enough food could be produced with lower-yielding organic farming, if people become vegetarians or eat a more plant-based diet with lower meat consumption. The existing farmland can feed that many people if they are all vegan, a 94% success rate if they are vegetarian, 39% with a completely organic diet, and 15% with the Western-style diet based on meat.
