  1. Demographic and Landscape Change in the Lake Pátzcuaro Basin, Mexico: Abandoning the Garden Christopher T. Fisher’s Presented by Lisa McDevitt

  2. 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). http://www.anthro.illinois.edu/faculty/cfennell/syllabus/anth453/wood1.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  3. Christopher T. Fisher, PhD • Archaeologist, Associate Professor, Colorado State University • Received PhD and MA from University of Wisconsin-Madison • Research focuses on the links between humans and their environments, both past and present • Conducted fieldwork throughout the U.S., Mexico, Portugal, and Albania • Director of Legacies of Resilience, a long-term research endeavor to explain socio-ecosystem evolution over large time scales Image: http://resilientworld.com/wp-content/uploads/2008/04/fisher_notescrop.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  4. Background • Why the Pátzcuara Basin? • Previous Conflicting Research: • Descendents of Tarascan empire possess “intrinsic knowledge” of nature (Toledo 1991) • Ancient farming techniques caused significant erosion (O’ Hara et al. 1993) http://www.1st-art-gallery.com/thumbnail/141149/1/The-Tarascan-Civilisation,-1942.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  5. What caused the land degradation?

  6. What Is Land Degradation? “Environmental change initiated by humans that results in a perceived productivity loss” http://orbisunumlana.files.wordpress.com/2012/03/v9909e011.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden http://upload.wikimedia.org/wikipedia/commons/7/7b/Erosion.jpg

  7. “Gardenization” and Landesque Capital • “Degradation Time Clock” • “What happens to the garden once it is abandoned?” http://www.nature.com/scientificamerican/journal/v15/n1s/images/scientificamerican0105-90sp-I5.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  8. Methods • Collection of Earth Science (i.e. sediment samples, depositional profiles, and erosional features) and Archaeological Data at several sites around the Lake PátzcuaroBasin • Analysis of Surface Remains • Analysis of soil characteristics and soil structures as indicators of erosion Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  9. Findings Image:http://www.davehaskell.com/images/tzintzuntzan.jpg Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden

  10. 3 Conclusions: http://www.crowcanyon.org/about/press_releases/pr_06_01_05_pic.jpg • Degradation in the Lake Pátzcuaro basin began with the formation of the TarascanEmpire • Landscape stability was maintained as population grew. • 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

  11. Impact • Idea that adopting the practices of indigenous farmers will aid in conservation is flawed • Converting “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 Demographic and Landscape Change in the Lake Patzcuaro Basin, Mexico: Abandoning the Garden
