In Origins of Agriculture in Western Central Asia, archaeologist David R. Harris addresses questions of when, how, and why agriculture and settled village life began east of the Caspian Sea. The book describes and assesses evidence from archaeological investigations in Turkmenistan and adjacent parts of Iran, Uzbekistan, and Afghanistan in relation to present and past environmental conditions and genetic and archaeological data on the ancestry of the crops and domestic animals of the Neolithic period. It includes accounts of previous research on the prehistoric archaeology of the region and reports the results of a recent environmental-archaeological project undertaken by British, Russian, and Turkmen archaeologists in Turkmenistan, principally at the early Neolithic site of Jeitun (Djeitun) on the southern edge of the Karakum desert. This project has demonstrated unequivocally that agropastoralists who cultivated barley and wheat, raised goats and sheep, hunted wild animals, made stone tools and pottery, and lived in small mudbrick settlements were present in southern Turkmenistan by 7,000 years ago (c. 6,000 BCE calibrated), where they came into contact with hunter-gatherers of the "Keltiminar Culture." It is possible that barley and goats were domesticated locally, but the available archaeological and genetic evidence leads to the conclusion that all or most of the elements of the Neolithic "Jeitun Culture" spread to the region from farther west by a process of demic or cultural diffusion that broadly parallels the spread of Neolithic agropastoralism from southwest Asia into Europe. By synthesizing for the first time what is currently known about the origins of agriculture in a large part of Central Asia, between the more fully investigated regions of southwest Asia and China, this book makes a unique contribution to the worldwide literature on transitions from hunting and gathering to agriculture.
During his years as a scientist working for the British government in India, Sir Albert Howard conceived of and refined the principles of organic agriculture. Howard’s The Soil and Health became a seminal and inspirational text in the organic movement soon after its publication in 1945. The Soil and Health argues that industrial agriculture, emergent in Howard’s era and dominant today, disrupts the delicate balance of nature and irrevocably robs the soil of its fertility. Howard’s classic treatise links the burgeoning health crises facing crops, livestock, and humanity to this radical degradation of the Earth’s soil. His message—that we must respect and restore the health of the soil for the benefit of future generations—still resonates among those who are concerned about the effects of chemically enhanced agriculture.
This book responds to the widespread recognition among experts that our educational system needs to change in order to provide the skills and knowledge necessary to ensure the future vitality of U.S. agriculture. Understanding Agriculture focuses on agricultural literacy (education about agriculture) and vocational agricultural education (education in agriculture). The section on agricultural literacy addresses the teaching of science through agriculture, teacher education and training, model educational programs, community support, and agricultural career exploration programs. Vocational agricultural education is examined in terms of program enrollment, availability and content, supervised occupational experiences, the Future Farmers of America program, and teacher education and supply.
