MAN AND ENVIRONMENT IN EASTERN
                            SAUDI ARABIA
                           by J. H. STEVENS




        While man-environment relationships have become of crucial
        importance in the highly organised technological society of Western
        Europe, they have not, as yet, become major issues in desert
       ecosystems. Yet of all the world’s ecosystems, those of desert regions
       are perhaps the most imperfectly understood. Even without the
       presence of man, there exists a delicate balance between the
       non-living environment and the plant and animal communities. In the
       most primitive societies, man lives within the constraints imposed by
       the environment and any dislocation to the system results in areas
       becoming uninhabitable. However, as society’s requirements become
       more complex and technologically orientated, the ecosystem can be
       easily, and rapidly, disturbed, perhaps to the point where the
       disturbance is irreversible, unless constant vigilance is maintained.
       Fortunately, this extreme state is not evident in the Eastern Province
       of Saudi Arabia and, indeed, the reverse is the case for there are
       examples of where technology has improved the environment to make
       it more suitable for human settlement.
          Prior to the discovery of oil, Eastern Province exhibited the
       dualism that characterises human society in desert regions. On the
       one hand, there were the oases, such as those at al-Hasa or QatTf,
       with their sedentary populations mainly engaged in cultivation with
       some livestock rearing. In these oases, the cultivation of date palms
       CPhoenix dcictylifera) assumed paramount importance but whether
       this was due to human requirements or to an adverse physical
       environment, man induced, is unclear. Fodder crops, such as alfalfa,
       were of secondary importance. Such oases were located where there
       was an accessible supply of suitable water — at al-Hasa, the large oasis
       area was watered from artesian springs, but other small irrigated
       areas, only a few dunums* in extent, relied on water in wadi gravels
       that could be exploited by shallow wells.
