Can we feed 10 billion people on organic farming alone?
Organic agriculture occupies only 1% of global agricultural land, making it a relatively untapped resource for one of the greatest challenges facing humanity: producing enough food for a population that could reach 10 billion by 2050, without the extensive deforestation and harm to the wider environment.
That’s the conclusion my doctoral student Jonathan Wachter and I reached in reviewing 40 years of science and hundreds of scientific studies comparing the long term prospects of organic and conventional farming. The study, Organic Agriculture in the 21st Century, published in Nature Plants, is the first to compare organic and conventional agriculture across the four main metrics of sustainability identified by the US National Academy of Sciences: be productive, economically profitable, environmentally sound and socially just. Like a chair, for a farm to be sustainable, it needs to be stable, with all four legs being managed so they are in balance.
