Giles, Jr. Co-Chairman Robert G. Dyck, Co-Chairman Environmental Design and Planning (ABSTRACT) The purpose of this dissertation is to develop an approach which may aid decision-makers in the arid regions of the Middle East in formulating a comprehensive and operational set of landscape planning objectives. This purpose is sought through a dual approach; the first deals with objectives as the comerstone of the landscape planning process, and the second focuses on objectives as a signiiicant element of regional development studies. The benefits of developing landscape planning objectives are discussed, and contextual, ethical, political, social, and procedural diliiculties are examined. The relationship between setting public objectives and the rational planning process is surveyed and an iterative model of that process is suggested. Four models of setting public objcctives are compared and comprehensive criteria for evaluating these and other ones are suggested. Three existing approaches to determining landscape planning objectives are described and analyzed. The first, i.e., the Problem-Focused Approach as suggested by Lynch is applied within the context of typical problems that challenge the common land uses in the arid Middle East. The second, i.e., the Inductive Approach, which is currently used by most landscape pla.nners, is examined through studying iive key development projects in Saudi Arabia, Bahrain, and Egypt. The third, i.e., the Deductive Approach, is used as a foundation to a proposed Landscape Planning Objectives System (LAPOS). LAPOS consists of diverse activities with a common purpose: clarifying and quantifying objectives. Ranking objectives within LAPOS is based on the computation ofa grand index for each objective. Computing a grand index encompasses measuring six dimensions for each objective, i.e., space, time, population, demand, marginality, and failure index. Dedication In the name of God, the Most Beneiicent, the Most Merciful. This work is dedicated to my mother and the soul of my father. Dedication Acknowledgements I am deeply grateful to God for granting me the guidance and the strength needed to accomplish this work. I would like to thank all the members of my advisory committee for their support, and under- standing. It is very difficult to separate the valuable help that the committee members have offered, both in- dividually and jointly. Bearing in mind that difficulty, it is still possible to state some of the members specific contributions. The greatest debt of gratitude I owe is to my chief critic, editor, advisor, Robert H. Giles. Professor Giles served not only in the routine chores of commenting upon the work, but above all as my literary and intellectual conscience. I am particularly indebted to him for his assistance in selecting the research topic and in guiding the design and the conduct of the study. As a co-chairman of my advisory committee, Dr. Dyck has offered personal support, technical ad- vise and generous time which will be always appreciated. Dr. Ochsenwald has been most sensitive to, and understanding of, the historic dimension which is characteristic of this and similar research work. Hence, his input and assistance have been most valuable in Upgfadlilg the case studies sec- Acknowledgements v tion, clarifying intricate cultural concepts, and balarrcing the overall direction of the research. Dr. Randolph played a major role during my first year of studies at Virginia Tech. Dr. Rahman’s friendly involvement has provided me with personal motivation and faith that the subject is an important one.
