By 2050, we will need 56 percent more food to feed 10 billion people, according to the World Resources Institute. But our global food system is challenged by climate change. How can we create a sustainable food system without using more land? Florence Reed works with farmers in Central America to restore degraded farmland and introduce regenerative farming practices. She is the founder of Sustainable Harvest International. “If all 500 million of those smallholder farmers around the world made this transition, they could get us 53% of the way to the United Nations goal for greenhouse gas reductions,” she said.
