Monks on the temple steps of Angkor Wat.
International scientists using new archeological, pollen and tree-ring dating evidence contend that Angkor crumbled due to urban sprawl and extreme weather conditions.
Sydney University archeologist Roland Fletcher ~ a co-director of the Greater Angkor Project, an initiative involving Cambodian, French and Australian experts ~ said he believed the new findings carry "clear implications for modern cities."
The scientists believe that before an alternating series of droughts and monsoon floods hit Angkor from the mid-14th to late 15th centuries, the capital of the Khmer empire had already had extensive problems with its vast, complicated water system.
Ultimately, it became impossible for the city to keep pace with further pressures from extreme weather. Although there was ongoing conflict with neighboring states, it was the over-built water infrastructure that locked Angkor into a trajectory of decline.
Before Angkor vanished into the jungle in the 17th century, it was the world's largest low-density pre-industrial city. Between the ninth and 13th centuries, the metropolis was home to as many as 750,000 people.
