                       Prior to the unification of the country by King Ibn Saucl, the
                     Bedouin tribes were frequently at war with each other and the
                    capture of another tribe’s livestock was a constant aim. Warfare and
                    feuding served to keep the total number of livestock within the limits
                    imposed by the physical environment. With political stability, the
                     numbers of livestock increased and while total numbers may not be
                    out of balance with the resources provided in the area available,
                    overgrazing has become a major problem especially in Eastern
                    Province which, during the 1960s, suffered from severe drought.
                       The rainfall regime of eastern Saudi Arabia is very irregular and
                    any storms are often localised. In drought periods, there is
                    concentration of livestock on areas where there is good grazing or
                    where water is available and this causes marked overgrazing. The
                    problem is being accentuated by the increased mobility that is
                     available to the nomads through the advent of trucks and the
                     evolution of a modern road network — the author has witnessed the
                     loading of a flock of sheep onto a truck in the desert near the
                     Khurais oilfield for transport to an area south of al-Hasa oasis where
                     the grazing was substantially better. Additional water resources have
                     been discovered and the Ministry of Agriculture and Water are
                     providing more wells but the numbers are still insufficient to
                     overcome the problems of concentration of livestock in drought
                     periods.
                       However, the deterioration of the ranges has not just been caused
                     by the pastoralists. The upsurge in urban population in the Eastern
                     Province that was a direct result of oil exploitation led to an increase
                     in the demand for fuel. Allred (1968) comments that the fuel
                    gatherer takes the roots, stems and trunks of the perennial plants.
                    The resources of the rangeland for grazing must be assessed on the
                    quantity and type of perennials, for it is these plants which provide
                     the grazing during drought periods and thus the ultimate carrying
                    capacity of the land. As the perennials are removed or destroyed,
                     they are replaced by annuals, which, while they may provide a more
                    nourishing feed for animals in the good years, cannot survive drought
                    periods. The effects of drought are a far more potent force than
                    those resulting from seasons of good rainfall.
                       Of particular interest in man-environment relationships is the
                    position that the nomadic pastoralists are to occupy in modern
                    society. There is to be increased emphasis on livestock production in
                    ttie national economy and this will have to result in better
                    management of the range lands. The first steps have already been
                    taken — range improvement experiments have been initiated in the
                    west of the Kingdom, near Jeddah and Taif, and these will eventually
