We've all got to eat. And climate change is throwing us new challenges as to how to feed a global population that's getting bigger, more urban, and more affluent  -- and make sure the world's poorest have enough nutritious food too.

This would have been a challenge without climate change.  With it, farmers need to adapt to wilder weather, less predictable rainfall, and shifting growing zones that sometimes mean they can't plant what they long did, and have to find new crops that are resilient to the new normal.

Meanwhile, efforts are afoot to cut emissions that agriculture itself contributes to climate change.

In this episode, breaking down this complex set of issues  in simple terms, with on-the-ground knowledge are:
