Abstract


 This study was conducted in the Al-Ubayyid Area in North Kordofan State (1985 to 2014), its aim was to assess the Land use/cover change using Remote Sensing and GIS technologies. A supervised (Maximum likelihood) method was implemented for land cover classifications. The overall results from the change detection report show a noticeable change in the land use classes during the study period of (1984 – 2014. During the period 1984 – 1994, there was a decrease of bare land 1 and vegetation, and a significant expansion of urban areas; this might go back to heavy migration of rural people to the city due to conflicts and drought. During (1994 – 2014), there was an observable loss of sand and water, and a gradual increase of vegetation; this might be attributable to intensive afforestation programs followed by the construction of the green belt of Al-Ubayyid area. During the period 1984 – 2014,  there was a dramatic increase of bare land 2 and urban areas, and a decrease of bare land 1 and sand. The research concludes that urban growth has led the city to expand outward at the expense of vegetation cover and bare land. However, in the absence of wise; land management, serious land use problems will occur in the near future. This might negatively impact the ecosystems of the whole area of North Kordofan State.

 

المستخلص: أجريت هذه الدراسة في منطقة الأبيض بولاية شمال كردفان خلال الفترة (1985 - 2014) بهدف تقييم استخدام الأرض وتأثيره على الغطاء النباتي بتقنيات الاستشعار عن بعد ونظم المعلومات الجغرافية. أشارت النتائج الكلية بان هناك تغيرا ملحوظا في أصناف استخدام الأرض خلال فترة الدراسة.  ففي الفترة 1984 - 1994 كان هناك انحساراً في الأراضي الجرداء (1) والغطاء النباتي، وتمدد الرقعة الحضرية، ويعزى هذا إلى النزوح الكثيف لسكان الريف والقري المجاورة إلى المدينة بسبب النزاعات والجفاف. خلال الفترة من 1994 إلى 2014 كان هناك إنحسار ملحوظ للرمل والماء، وزيادة تدريجية في الغطاء النباتي؛ ويعزى ذلك إلى برامج التشجير المكثفة وإنشاء الحزام الأخضر لمنطقة الأبيض. خلال الفترة من 1984 إلى 2014 كان هناك توسع شاسع في الأراضي الجرداء (2) والمناطق الحضرية وإنحساراً في الأراضي الجرداء (1) والرمال. يخلص البحث إلى أن هناك تمدد عمراني واسع النطاق على حساب الغطاء النباتي والأراضي الجرداء، وهذا قد يؤدي إلى ظهور مشكلات كبيرة في استخدام الأرض في المستقبل القريب، وإذا لم تتوافر الإدارة السليمة لإستخدام الأرض قد تؤثر هذه المشكلات سلباً على النظم الإيكولوجية لولاية شمال كردفان بأكملها.
