Under the Paris Agreement, countries were asked to present their own climate action plans, and 90 percent of these action plans -- technically called NDCs, for "nationally-determined contributions" -- incorporated farming fixes -- or shiftint to sustainable agriculture. That led to a major breakthrough this week at year-end climate talks here in Bonn, Germany, where our guest is Tonya Rawe, who runs the Food and Nutrition Security program at CARE International.

CARE is a humanitarian aid organization formed in the wake of World War II, but it's become a key player in the environmental space as well, especially when subsistence farmers are involved.
