A third of the world’s food production is at risk from the climate crisis, research has found – but at the same time our food systems are one of the key contributors to climate breakdown. Greenhouse gas emissions from farming and the land use change that often accompanies it, such as clearing forests and drying out wetlands to make room for crops and livestock, amount to more than a fifth of global carbon output, according to the Intergovernmental Panel on Climate Change.
But discussions of the world’s food systems, their vulnerability and their impacts, are confined to the sidelines of the annual UN climate change negotiations and given scant attention.
