México Indígena is a project of the American Geographical Society to organize teams of geographers to research the geography of indigenous populations in Mexico.  The project's stated objective is to map "changes in the cultural landscape and conservation of natural resources" that result from large scale land privatization initiatives underway in Mexico.  The project is led by Peter Herlihy at the University of Kansas and is funded by the U.S. Department of Defense through its Foreign Military Studies Office.  The project has been the subject of criticism by various groups including groups representing indigenous peoples.
