This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail

This fascinating book examines the biology and culture of foods and beverages that are consumed in communal settings, with special attention to their health implications. Nina Etkin covers a wealth of topics, exploring human evolutionary history, the Slow Food movement, ritual and ceremonial foods, caffeinated beverages, spices, the street foods of Hawaii and northern Nigeria, and even bottled water. Her work is framed by a biocultural perspective that considers both the physiological implications of consumption and the cultural construction and circulation of foods.

How did imported technology contribute to the development of the colony of Singapore? Who were the main agents of change in this process? Was there extensive transfer and diffusion of Western science and technology into the port-city? How did the people respond to change? Examining areas such as shipping, port development, telegraphs and wireless, urban water supply and sewage disposal, economic botany, electrification, food production and retailing, science and technical education, and health, this book documents the role of technology and, to a smaller extent, science, in the transformation

Crop Resources contains papers that were originally presented as a symposium on Crop Resources at the 17th Annual Meeting of the Society for Economic Botany in Urbana, Illinois, 13-17 June 1976. The volume attempts to evaluate (a) the possible nonfood uses of cultivated plants; (b) the extent to which new and additional food resources may become available; (c) the prospects of several specialized uses of plants such as drugs, insecticides, rubber, and condiments; and (d) the origin of four major crops of the American Midwest and prospects for their future development. The discussions include t
