This study aims to show the land use changes during the period 1970 – 1991. The study includes the city of Homs and the surrounding areas, with total surface area of 9686 ha. To carry out this study, aerial photographs were used where sets of different periods were taken, one was taken in 1970 with a scale of 1/20000, and the other set for the year 1991 with a scale of 1/15000, the two sets of aerial photographs were interpreted and analyzed after the delineation of the targets, and two maps were prepared after unifying the scales and selecting the proper legend. The results indicated obvious changes in land use, for example, the area of cereals crops was in 1970 about 32.9 % of the total area and decreased by 11.8 % in 1991. In the area of gardens a reasonable increase was recorded, while in the area of vineyards an increase of about 1 % was noticed. But the big issue is the urban expansion at the expense of arable lands, the expansion area of housing has been increased from 8% in 1970 to 24% in 1991, and the area of civil establishments was increased from 2.27 % in 1970 to 5.47 % in 1991, in the new concept of desertification urban expansion at the agricultural land means a permanent desertification, this matter should be considered seriously and the necessary measurements must be taken into account.

Research summary
تهدف هذه الدراسة إلى تحليل التغيرات في استعمالات الأراضي في مدينة حمص ومحيطها بين عامي 1970 و1991 باستخدام تقنيات الاستشعار عن بعد. شملت الدراسة مساحة إجمالية قدرها 9686 هكتار. استخدمت صور جوية بمقياس 1/20000 لعام 1970 و1/15000 لعام 1991 لتحليل التغيرات. أظهرت النتائج تراجعاً كبيراً في زراعة محاصيل الحبوب من 32.9% إلى 11.8% وزيادة في مساحة الأبنية والمنشآت المدنية من 8% إلى 24% و2.27% إلى 5.47% على التوالي. تشير الدراسة إلى أن الزحف العمراني على الأراضي الزراعية يؤدي إلى تصحر دائم، مما يستدعي اتخاذ إجراءات للحفاظ على الأراضي الزراعية ومنع خسارتها.

In developing countries, where resources are often scarce, land availability, productivity potential, capability and sustainability for agriculture and, planning and maximizing the use of the land resources for a particular land utilization type is e ssential. In order to ensure appropriate decision and, continued and sustainable productivity, thereby continuing to support the population economically without degradation, land use planning is essential. Remote sensing (RS) and geographic information systems(GIS) are useful tools in land use planning processes .in this study 4 landscape units (costal leveled plains ,valleys and channel bed, Piedmont :slight slopping ,moderately slopping ,sever slopping ,and Summit unit) were described and compared its characteristics with the land utilization requirements for 6 land utilization types (LUT1: irrigated citrus low mechanized ,LUT2: irrigated potato high mechanized ,LUT3: irrigated tomato medium mechanized,LUT4: rainfed olive low mechanized,LUT5:rainfed wheat low mechanized, LUT6:natural forests)by using LAMIS program .the results showed that43.07% of studied area is moderate suitability S3, 27.9% is low suitabilityS4 ,and 20.24% is unsuitable N1.the land suitability evaluation for LUT2 :35.18% good suitability S2 ,35.17% moderate suitabilityS3 and 20.24% low suitability S4 and for LUT3:50.97% good suitability S2,20.04% moderate suitabilityS3 and 20.24% low suitability S4. 43.07% of lands are very suitable S1 for LUT4 ,27.91% good suitability S2 and 20.24% moderate suitabilityS3.for LUT6 ; land suitability evaluation shown that 59.24% of lands are very suitable S1 and 31.93% good suitable S2. Land use planning processes include matching between physical and socio-economic conditions by using Definite program .optimal land utilization types are determined depending on 3 multi-criteria ( costs ,gross margin , water requirements for irrigation) and according to two scenarios ( SC1:conservative scenario with concerned to water requirements , SC2:economic scenario with concerned to gross margin ).the results showed that LUT4 is the optimal current land use type of all three physiographic units (costal leveled plains ,valleys and channel bed and slight slopping).2 suggested land utilization types ( LUT7:irrigated kiwi low mechanized ,LUT8:irrigated groundnuts high mechanized) are proposed to costal leveled plains and compared with LUT4,comparison results shown that LUT4 is the optimal land use according to SC1 and LUT7 is the optimal land use type according to SC2.for valley and channel bed unit , the optimal land use type according to SC1 is multiple land use type ( rainfed wheat under rainfed olive trees) and according to SC2 is LUT7.3 land utilization types(LUT7,LUT8,LUT9: rainfed lentil low mechanized)are suggested for slight slopping piedmont .the results of planning process showed that the optimal land use type is LUT4 for both scenarios SC1,SC2.
Al- Qusier region is important agricultural areas in Syria, and contribute to cover a significant part of the agricultural needs of the country ,but it was suffering of poor land use in some locations. This study aims to prepare maps of land use an d land cover using remote sensing and geographic information systems (GIS) techniques, the study relied on SPOT-4 satellite images with spatial resolutions 10 m for (white–black) images and 20 m for color images. The study found a view of results were the ability of remote sensing and geographic information systems in the production of accurate maps of land use/land cover and establish a digital database for spatial land use and land cover for Al- Qusier region.
Studying of land use changing Detection needs to the speed of implementation to convoy the changes on the ground. the traditional ways in the analysis and visual interpretation of the images and field studying need a lot of time and effort. So The objective of this search is to classify group images (Landsat TM , ETM+) taken in different dates automatically, and then to calculate the area of each land use/land cover, during the years studied (1990 -2000- 2010) and comparison areas to identify the most important changes occurring during that period.
This study was related to the urban development of Homs City and its surrounding between 1972 – 2010 by using remote sensing technique and geographic information system. The results of the study indicated that the size of the city was increased 60 0% times , randomly and eliminating most of crop lands.
Jaramana city is located within the area of Al-Ghouta Al-Sharqia, which is known by its fertile soil, and close to Damascus city. The availability of services and job opportunities would spot the light on Jaramana city and attract new residents. T his was observed during a study extended between (2003-2017) m. In addition to the fact that the city has remained save and secured during the crisis which waged on the country since (2011) m.
