Climate change is impacting the lives of potato farmers in the Andean region, intensifying damage from pests and diseases, increasing risk of soil erosion and contributing to loss of biodiversity. In this award-winning presentation at the 10th World Potato Congress in Cusco, Dr. Graham Thiele, Director of the CGIAR Research Program on Roots, Tubers and Bananas (RTB) looks to the past to see what lessons can be drawn from the way in which the Wari and Inka Empires adapted to a warming climate one thousand years ago.
