From the Foreword The world s dramatic awakening to the impact of ecology on the quality of human life, and a new awareness of the potential for exploitation of the desert environment in which our particular interest lies give rise to more thoughtful, even sober, attention to the problems faced by those aspiring only to bigger yields from crops and more protein from animals. To these very basic needs of food and fiber, we are, therefore, addressing ourselves further to a consideration of housing, educational programs, and nonagrarian resource evolution, to the end that the planners and the decision makers may have the benefit of the most intelligent and contemporary understanding possible of the cultural and social aspects of arid lands as well as the latest technological advances on a wide-ranging spectrum of scientific developments.
