Changes in the orientation of archaeological research in the post-World War n period affected Maya studies. The cultural ecological perspective, which was rising to prominence, put an old debate in bold relief: How had this prehistoric civilization adapted to the tropical forest environment? How could swidden cultivation have sustained the unexpectedly high population densities that settlement pattern studies appeared to be revealing? Had the ancient Maya practiced some from of intensive agriculture? Archaeologist Dennis E. Puleston went to the Maya Lowlands to investigate geographer Alfred H. Siemens's reports of possible intensive agriculture ("ridged fields") seen from the air and to study prehistoric Maya cultivation and civilization from a cultural ecological perspective. This volume presents the results of the Rio Hondo Project field research on Albion Island in northern Belize from 1973 to 1980 with the addition of selected results from Pohl's continuing work in northern Belize.
