LandUse/landCover changes occurred from 1973 to 2010 and land degradationrnsusceptibility analyses were investigated in Kutaber wereda of South Wollo Zone;rnAmhara regional state, on an area of 719.92 km2 which was monitored using geospatialrntools together with field verifications. In addition to these, different metrological and otherrnancillary data were used for the study. The study area is a reflection of the Ethiopianrnhighland degradation in many ways because of land degradation, deforestation, landrnfragmentation, steep slope cultivation are also common features in the study area.rnThese problems have been the driving forces to Landuse/landcover changes in manyrnparts of Ethiopia. The objective of this study is to understand and analyze the long termrndynamics of Landuse/landcover change and developing the susceptibility of landrndegradation map. Results from landcover change dynamics show an increase inrnagricultural land from 21.59% in 1973 to 51.76% in 2010, with mainly at the expense ofrngrass land, forest land and Shrub land respectively. On the contrary, forest land, shrubrnland and grass land decreased from 15.21%, 27.58% and 20.6% in 1973 to1.2%,rn21.78% and 4.05% in 2010 respectively. Due to the rapid expansion of urban and ruralrnsettlement in the second period (1986 – 2010) shows that 8.65% of settlement existed inrn2010, with mainly at the expense of grass land. Rate of landcover change and landcoverrnconversion matrix clearly showed that the dynamics of different landcover classes overrnthe study periods. Land degradation susceptibility map of the study area have beenrnproduced using multi criteria decision evaluation. Five model parameters: slope, landusernclasses, soil type, population and Rain fall intensity have been used to run thernsusceptibility model. The result of land degradation susceptibility analyses showed thatrn12.92% the area is very highly susceptible, 23.74% highly susceptible, 24.34%rnsusceptible, 25.08% less susceptible and 13.92% very less susceptible to landrndegradation. The majority of the area falls on susceptible, highly susceptible and veryrnhighly susceptible to land degradation (61%). The resultant land degradationrnsusceptibility map along with the Landuse/landcover can serve local planners andrnresearchers as a primary source of information for NRM of the study area.rnKey words: Landuse/Landcover, land degradation susceptibility model, Dynamics.
