Book Description
The hot and temperate deserts and their marginal steppe lands comprise one-third of the land surface of the world and are an increasingly critical area for the economic wellbeing of world populations. The remarkable mechanisms of floral, faunal, and human adaptation to the distinct and difficult environment of these arid zones, as well as the potential of modern technology for facilitating adaptation, are described and explained by Walton in the light of our most recent knowledge of the phenomena and processes involved.Beginning with a clarification of the definitions of arid and semi-arid regions and with the delineation of techniques for measuring the degree of aridity in these areas, the author shows that there is wide variation among the arid zones in landscape and climate and that there are numerous local and microclimates within any single arid region. The life cycles of the plants and animals of the arid zones are described and the water resources, including problems of salinity, mineral contamination, and the construction of reservoirs, are examined. Extensive treatment is given to potential agricultural adaptations and to pastoralism as the most widespread response to dry land. A final chapter summarizes attempts at adaptation to prevailing drought and discusses the kinds of future development that the author deems most likely in arid zones.Throughout the book emphasis is placed on specific, detailed analysis, with adequate tables and formulas for in-depth understanding of particular aspects of aridity. Examples from both Old and New Worlds are used to demonstrate the spheres in which progress is being made and to show the mistakes in past and present land use in arid areas. An essential supplement for courses in physical geography, the book will be useful in many area studies and in studies of economic development.

Book Description
In 1951 UNESCO launched an Arid Zone Programme with the object of promoting research into arid regions from every relevant scientific point of view. This book, originally published in 1966, represents the range of research undertaken and gives a general conspectus of arid zone geography. 17 authors from 8 countries contributed and the book deals comprehensively with all the main areas, with specific examples used to illustrate arguments. There are chapters on meteorology, geology, geomorphology, botany and zoology and almost 50% of the book is devoted to man’s activities: irrigation and agriculture; industry; animal breeding and human survival in the desert

Book Description
The international conference Arid Lands: Today and Tomorrow drew more than 400 participants from over 3 S countries to Tucson, Arizona, for one week in October of 19 8 S. The diversity of presenters, disciplines and subject matters addressed contributed to an interesting and informative conference. The papers presented in this volume represent the efforts of scientists and other individuals who, through their various disciplines, are addressing the problems of and opportunities presented by the arid lands of the world. A committee of five scientists reviewed for substance. relevance and their contribution to the conference the 284 abstracts that were submitted. They selected 146 for presentation at the conference and of those papers presented, 128 were received for inclusion in the proceedings.

Book Description
In this study energy-exchange processes and climatic influences are examined in relation to thermal comfort and work efficiency as exemplified in a schoolroom situation. The investigation tests fundamental hypotheses on meterotropisms and optimal thermal environments and demonstrates how daily variations within atmospheric environments are considerably more important than had been previously suspected. It also describes the experimental use of a variety of microclimatic instruments and thermal indices in conjunction with psychological tests of continuous mental performance. The Atmospheric Environment treats a complex problem from a broad multi-disciplinary standpoint and is of particular interest to climatologists, psychologists, teachers and educational administrators, heating and ventilating engineers, and to all concerned with environmental management.

Book Description
How to Find Out About Economics focuses on information sources related to economics, including books, periodicals, government publications, and national and international organizations. The sources of arranged according to the Dewey Decimal Classification used by many libraries. This book is comprised of 17 chapters and begins with an overview of modern economics and guides to careers in economics. The following chapters focus on sources of employment registers and careers advice in economics; career and vocational guidance in the United States; and career patterns for economists. The discussion then turns to two categories of information relating to economics: bibliographical sources such as books, periodicals, abstracts, and similar printed documents; and non-bibliographical sources such as organizations and societies formed, for example, by economists or persons having an interest in economics. The book also considers libraries and their functions; guides to library resources; sources of education for careers in economics; and sources of economic history, business history, and biography. This monograph will be a useful resource for students and others interested in embarking on a career in economics.
