To cope with this problem, a land suitability assessment has become an essential tool for sustainable land use management. The present research qualitatively evaluated the suitability of land in the Al-Yarmouk Basin (S-Syria) for rainfed winter wheat (Triticum aestivum) cultivation. In this study, a regional spatial approach involving three steps was developed, based on the method proposed by Sys et al. In the first step, a soil survey was carried out and 107 soil profiles were described, sampled and analyzed. In the second step, climatic gridded datasets from 1984–2014 MRm at a high spatial resolution (30 meters) and the Digital Elevation Model (DEM) were clipped from NASA's Shuttle Radar Topography Mission (SRTM) and prepared for the study area. In the third step, a land suitability assessment was performed using the geographical information system (GIS) and multi criteria decision support (MCDS). Soil survey outcomes showed that the study area was dominated by five soil orders: Mollisols, Inceptisols, Vertisols, Entisols and Aridisols. Also, results from the Sys model illustrated that more than 23.8% of the study area is highly suitable (S1–0) for wheat production without any limitations, whereas 38.7% and 37.5% are highly suitable (S1–1) and moderately suitable (S2), respectively. Also, the study emphasizes the important role of topographical factors in the study area for wheat cultivation. All in all, this research suggests W-Syria as a potential region for wheat cultivation, instead of the eastern area which is subject to climate change and a shortage of water. Integrating the Sys-approach and the GIS framework offers a good tool for policy-makers to apply in Syria for land suitability assessments.

An integration of bioclimatic, soil, and topographic indicators for viticulture suitability using multi-criteria evaluation: a case study in the Western slopes of Jabal Al Arab—Syria / Karam Alsafadi in Geocarto international, vol 35 n° 13 ([01/10/2020])

Moreover, recent advances in GIS tools and methods have helped decision-makers as well as farmers to find optimal sites for production of different crops. The cultivation of vineyards and grapes is one of the most important agricultural activities in the Al-Sweidaa governorate—Syria, which has been suffering from a decrease in annual productivity in conjunction with an increase in the annual demand for grapes and wine products, particularly in recent decades. Therefore, the aim of this research was to establish a new method for analyzing the optimum regions for economic viticulture production in the Western Slopes of Jabal Al Arab in the Al-Sweidaa governorate by using multi-criteria evaluation (MCE). To this end, a field survey was conducted and a soil sample was collected for physical and chemically analysis, and a 1984–2014 MRm.30-meter resolution dataset of climatic variables for the Al-Sweidaa governorate was set up as well. The results show that suitable areas are concentrated in the higher part of the study area (the eastern part) where climate and soil are favourable, and did not show any relevant limitations. Conversely, the lower part of the study area (the western) has unfavourable climate and soil chemical and physical fertility; therefore grape production is only possible if irrigation is applied and the fertility properties of the soil are improved, particularly the percentage of organic matter and the soil texture.
