This book was released on 2002-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a report on plants that show promise for improving the quality of life in tropical areas. Because the countries in this zone contain most of the world?s low-income populations this report is addressed to those government administrators, technical assistance personnel, and researchers in agriculture, nutrition and related disciplines who are concerned with helping developing countries achieve a more efficient and balanced exploitation of their biological resources.The 36 plants described here were selected from among 400 nominated by plant scientists around the world. (To keep the project to manageable size, medicinal plants and timber species were excluded.)

Download or read book Preceramic Mesoamerica written by Jon C. Lohse and published by Routledge. This book was released on 2021-05-30 with total page 713 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preceramic Mesoamerica delivers cutting-edge research on the Mesoamerican Paleoindian and Archaic periods. The chapters address a series of fundamental questions in American archaeology including the peopling of the Americas, human adaptations to late glacial landscapes, the Neolithic transition, and the origins of sedentism and early village life. This volume presents innovative and previously unpublished research on the Paleoindian and Archaic periods and evaluates current models in light of new findings. Examples include breakthroughs in dating Mesoamerica’s earliest sites and their implications for models of hemispheric colonization; the transition to postglacial patterns of settlement and subsistence; divergent pathways to initial sedentism; the possibility of Archaic-period monumentality; changing patterns of interregional exchange and interaction; and debates surrounding the origins of agriculture, ceramics, and full-time village life. The volume provides a new perspective on the Mesoamerican Preceramic for students and scholars in archaeology, anthropology, and history. Readers will come to understand how the Preceramic contributed to the emergence of the cultural traditions that anthropologists recognize as Mesoamerica.
