"Among all the sectors, climate change is expected to hit agriculture the hardest," says Carlos Watson, the Food and Agriculture Organization's representative to China. Watson said that we need to transform our agri-food system to a system that puts people at the center. He pointed out that farmers are the primary custodians of knowledge about their environment, agroecosystems, crops, livelihoods and local climate patterns. Farmers, owners of individual farms and food production companies are people who hold the key drivers to adapt and implement new practices, innovations and technologies for food security and sustainable production, he added.
