The incredible achievements of the Classic lowland Maya civilization and the subsequent disappearance of that culture have stimulated one of the greatest controversies of modern prehistory. A central element in the controversy is the role of the tropical forest lands in Maya agriculture and subsistence, and the purpose of this study is to identify

This book is the first to bring together all that is known about the humanly-modified and cultivated landscapes of Middle America just prior to the European conquest. It assesses the agricultural and human-environment conditions existing at that time, and its implications for various contemporary themes ranging from global change to the presumed 'environment friendly' Native American.

My interest in ancient Maya agriculture began late in the year of 1971 when William M. Denevan encouraged me to pursue the topic. Our interests had been perked by reports from Joseph W. Ball, JaCk Eaton, and Irwin Rovner of the presence of terrace-like features throughout the Rio Bee region of the soutnern Yucatan Peninsula. Denevan maintained a long-term interest in pre-Hispanic agriculture and population in the New World. Our studies with the emerging Rio Bee research group at the University of Wisconsin led to the conclusion that the then dominant themes of Maya agriculture were in need of reevaluation and that a number of remains of intensive forms of agriculture were likely to be found in the Central Maya lowlands of Mexico, Peten (Guatemala), and Belize, particularly wetland or raised fields in addition to the reported terraces. Our interests were heightened at this time by notification from Alfred Siemens of the finds of wetland fields in the vicinity of the Rio Bee region in the Chetumal, Mexico-northern Belize area.

The Anthropocene is an authoritative desk-top reference work for students of geography, the environment and sustainability. Through a series of 101 interconnected questions and answers spanning ten thematic sections, the book provides a comprehensive survey of humankind's impact on the global environment from the Late Stone Age to the present day. Unrivalled in scope, the book distills the latest research findings and scholarship across a remarkable range of topics concerning the evolving human-environment relationship. These include the broad history of human-induced changes in the environmental conditions of the planet; the major human impacts on the Earth and their consequences; and the different causes and rationales applied to understanding these environmental changes. All questions are answered succinctly and rigorously and draw on a wealth of contemporary evidence and scientific theories. The book is colour illustrated throughout, answers are fully cross-referenced and further readings are suggested for those wishing to delve deeper. For anyone seeking to understand the human-induced changes to our planet and the challenges these pose for sustainability, this book is an invaluable resource. It provides a masterly presentation of the human footprint on the Earth system.

This highly topical study of tropical deforestation reports on the first phase of a large, integrated, multi-institutional, and team-based study. Based in Mexico, it is designed to understand and project land changes in a development frontier that pits the rapidly growing needs of smallholder farmers to cut down forests for cultivation against federally sponsored initiatives committed to various international programmes of forest preservation and complementary economic programmes.
