Mayan_Collapse_Ecological

The ecological theories of Mayan decline usually focus on the worsening relationship between Mayan civilization and agricultural conditions in the late classic period. The archeological evidence has shown that the Mayans' agriculture was dependent on a simple slash-and-burn system. Based on it, the hypothesis of Soil Exhaustion was advanced by O.F. Cook in 1921. Similar assumptions are erosion and intensive agricultural and Savanna grass competition.
