In countries like Ethiopia where agriculture sector has the basic contribution for grossrneconomy, land resource plays a major role in the level of production. In this regard thernLanduse/Landcover dynamics and land degradation that can happen in a certain regionrnhas a serious pressure on the production of yield. Gozamin Woreda is one of the woredasrnfrom Esat Gojjam zone, which is known for its surplus food production. However thernland use/land cover dynamics and soil erosion occurred recently in the Woreda has putrnserious obstacle on the food security of the Woreda.To study the land use/land coverrndynamics Landsat 1 (MSS, 1972), Landsat 5(TM, 1986) and Landsat 7(ETM+, 1999) hasrnbeen used. The result during the period 1972 – 1999 shows that there is sharp increase inrncultivated land and grazing land, while there is a sharp decrease in bare land, and bushrnland. The other interesting result gained from this particular study the forest arearncoverage, which were only 3258.01(1.8 percent) of the total Woreda has increased torn4488.5764 (2.5 percent) of the total area. The basic reason for the increment of forestrncoverage in Gozamin Woreda is the afforestation program carried out by the thenrngovernment of Dergue. The final actual erosion result for the Woreda shows that thernvalue ranges from nil to 1056.8 tone/hectare/year and the mean erosion rate is 9.251rntonne/hectar/year. The final result expressed in terms of area coverage; actual soil lossrnless than 12 tone/hectare/year covers 72607 hectare (726.07 km2) of land and greater thanrnor equal to 12 tone/hectare/year and less than 211 tone/hectare/year covers 90471 hectarern(904.71km2) The remaining 16922 hectare (169.22 km2). From the total actual soil lossrnoccurred in the Woreda, 90 percent is below 211 tone/hectare/year. The remaining 10rnpercent of the total area is above 211 tone/hectare/year which can be said the high soilrnerosion rate in the Woreda. The findings of this particular research suggest that landrndegradation in the steep slopes is severe which need urgent intervention like afforestationrnprograms, terracing and other remedial solutions for the Woreda by integrating the localrnknowledge of the people.
