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.

What Went Wrong in Rondônia

In the late 1970′s, tens of thousands of Brazilian agricultural workers found themselves out of work due to technological advances on farms.  To combat the problem, the government, with help from the World Bank, set up a program to settle people into the rainforest and allow them to farm commercial crops.  The hitch? No one had tested the soil to see if it could support the crops being grown.  From there, the ambitious social and ecological experiment quickly turned into a nightmare of Hollywood proportions involving strife between ranchers and local tribes, clear cutting of the rainforest, and disease outbreaks of all kinds.  What can we learn from what went wrong in Rondônia?

Hidden Water

Most of the changes scientists see on our planet are either visible to the naked eye or directly measurable.  But changes to our water systems are among the most difficult to see.  In this episode, we travel from the Antarctic ice sheet capturing over 60 percent of all freshwater on Earth, to massive groundwater aquifers that remain particularly elusive, to a freshwater system that acts as the primary economic, cultural, and environmental driver of southern Asia.  In short, we go in search of hidden water.

History is a Mess

The very idea of an Anthropocene suggests that the world is changing faster than ever before.  And a growing number of historians, archeologists, and geologists are looking at our modern world in the context of deep time to place the rapid changes in their proper context.  In today’s show, Ian Morris discusses how societies have developed through all of human history – from Neanderthals to iPhones – and points out some trends we can extract and investigate from archeological data.  Specifically, Morris explains how geography drives human social development, but development changes the very meaning of geography.  If that sounds a little complicated… well, it is. But we speak with Ronan Arthur about the Native American Navajo as a sort of case study of this geography/social development concept.
