“…In arid and semi-arid areas, irrigation is an important measure to maintain high forage yield of lucerne pasture (Sheaffer & Tanner 1988;Shan et al 2008). Ironically, persistent irrigation can lead to salinised land (Omar et al 1998;Flowers et al 2000;Rozema & Flowers 2008). This salinisation of soils will inevitably threaten the persistence of lucerne pasture because lucerne is only moderately salt tolerant (Maas & Hoffman 1977).…”

Salinisation caused by irrigation is threatening the forage yield of lucerne pasture in the arid and semi-arid areas of west China. To select lucerne cultivars with good salt tolerance, the relative salt tolerance of five lucerne cultivars was assessed based upon shoot dry weight, shoot KV Na + ratio, leaf malondialdehyde (MDA) content and relative membrane permeability (RMP) at the seedling stage. NaCl reduced the shoot dry weight and shoot K + /Na + ratio, and enhanced the leaf MDA content and RMP in all cultivars, but the degree of either reduction or enhancement differed between these lucerne cultivars. Under 200 mM NaCl for 5 days, 'Rambler' had significantly greater shoot dry weight (only dropped 17.2% to 0.17 g plant-1) than other cultivars, and also maintained a better ion status, with higher K + content, lower Na + content, and thus a higher relative shoot K + /Na + ratio. 'Daye' was healthier because neither the MDA content nor the RMP was significantly increased in its leaves. Through combining the relative values of these indicators, the relative salt tolerance of the five cultivars A09014; Online publication date

“…The mean rate of population increase for the Gulf Cooperation Council (GCC) countries, plus Yemen, is variously estimated at 2.2 or 2.3% (CIA, 2010;UN, 2007). Omar et al (1998) have described a scenario in Kuwait where irrigated desert lands, with minimal rainfall and loss of natural vegetation to crop production activities, are prone to soil erosion, sand encroachment and increasing both soil and groundwater salinity. This pattern of change is reflected, at least in some of its manifestations, across the region.…”

Further from the northern coast of Oman new farm developments were more frequent than closer to the coast; they were also larger. The density of farms was highest close to Muscat although the distance enclosing 50% of farms had shifted away from Muscat during the study period. The dominance of Muscat is likely to be related to access to markets and infrastructure development. The increase in groundwater salinity was also highest close to Muscat and may be responsible for the shift in greenhouse density. Salinization of groundwater is severe close to the coast and was responsible for the reduced density of greenhouses near the coast. Land abandonment was highest close to Muscat and to the coast, reflecting changes in groundwater salinity and urbanization pressure. Less evidence was available for a direct shift from farmland to urban land use. Recent urban developments were largely located in areas already abandoned by agriculture. The paper also discusses likely future trends in land use change given that Oman’s population is increasing at over 2% annually and demand for urban land is increasing. The identification of a “salinity corridor” within which much of the future land use change may occur is discussed.
