Scars of the past

Beneath Cambodia’s troubled history with the Khmer Rouge lies a complex agricultural legacy that reaches back centuries. Once the symbol of a thriving region, we see how a prolonged El Nino brought drought and increased human conflict, and how the ruthless Pol Pot and his Khmer Rouge looked back to the temples at Angkor Wat and their proud agricultural heritage to motivate the atrocities of the Cambodian genocide. Producer Miles Traer speaks with mental health and water science experts to see how hundreds of years of agriculture have shaped the region. Traer shares his own thoughts on the relationship between food and conflict, and how he sees the standard historical narrative breaking down within Cambodia’s borders.

THIS EPISODE WAS PRODUCED BY LESLIE CHANG, MIKE OSBORNE, AND MILES TRAER.
