It is estimated that there are about 20 million km² of dry rangelands, where land deterioration tends to increase. Rangeland conservation should be based on information about natural and socio-economic conditions obtained by remote sensing. The current study which aimed at developing a proper grazing system for sustainable use of rangelands, was conducted in the northern steppe of Syria as a cooperative research project between ICARDA and T ARC from 1990.
The framework of the grazing system is shown in Fig. 10.
Remote sensing is useful to observe the wide rangelands and to acquire information for land use analysis.
