Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden
Landscape Archaeology (a.k.a. Human Ecodynamics)
“Few people, however, least of all our politicians, realize that a primary cause of the collapse of . . . [civilizations] . . . has been the destruction of the environmental resources on which they depended”
-Jared Diamond (2003:43).

Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden
Background• Why the Pátzcuara Basin?
• Previous Conflicting Research:1. Descendents of Tarascan empire
possess “intrinsic knowledge” of nature (Toledo 1991)
2. Ancient farming techniques caused significant erosion (O’ Hara et al. 1993)

What caused the land degradation?

What Is Land Degradation?“Environmental change initiated by humans that results in a perceived productivity loss”

Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden
3 Conclusions:1. Degradation in the Lake Pátzcuaro basin
began with the formation of the Tarascan Empire
2. Landscape stability was maintained as population grew.
3. The degradation in the area was the result of the unintended consequences of human action

Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden
ImpactIdea that adopting the practices of indigenous
farmers will aid in conservation is flawedConverting “wild” land to “garden” forces a
human-dependent environment; abandonment of the “garden” leads to trouble
A cycle of Creative Destruction and Destructive Creation in the human-environment relationship
More research necessary to better understand the matrix of factors contributing to land degradation
