Abstract:

In recent years, especially in arid and semi-arid areas, the degradation of land caused by climate change and human impact and the reduction of vegetation have made combating desertification, which has become an important environmental problem on a global scale. This study was carried out in order to determine the afforestation studies and the desertification tendency of Cankiri Karatekin University (?AKü) Faculty of Forestry. Dr. Abdülre?it BROH? Research and Implementation Forest, is about 5 km from Cankiri city center and has semi-arid characteristics. Desertification Indicator System for Mediterranean Europe (DIS4ME) which is developed for Mediterranean countries, was used to calculate the desertification risk (DR) and environmental sensitive area (ESA) sensitivity index. The study area was approximately 9,4 ha. Soil sampling was carried out at 30 points determined by taking into account the year of the afforestation studies in the area (1998-2004; 2009 -2015 afforestation studies) and desertification survey form was filled at each sampling point. As a result of the calculations made using the DIS4ME system; While ?R had the lowest risk with the lowest 1,69 and the medium risk class with the highest 5,25, the ?DA type values ranged from 1,35 to 1,52. Although the DR is low and medium in the study area, the study area is in the critical and fragile sensitivity class when evaluated together with the ESA type. Therefore, it is necessary to take necessary protection measures to ensure the sustainable land use, especially in the medium risk class and critical sensitivity level, and to increase the success of the afforestation works, which are of great importance in combating desertification
