Understanding of the driving forces of land use/ land cover change is essential for effective sustainable land resource management. Hence, this study was conducted to investigate land use/ land cover dynamics, its drivers and impacts in Nada Asendabo watershed,Gilge Gibe sub catchment of Ethiopia. It covers an area of 8,012 ha. Information Was extracted from three period land sat images (1973 MSS, 1986 TM and 2004 ETM+). Analysis of data was accomplished through integrated use of ERDAS imagine (version 9.2), Arc GIS software and SPSS version 16.00. Six land use/ land cover classes were selecte...

Information Was extracted from three period land sat images (1973 MSS, 1986 TM and 2004 ETM+). Analysis of data was accomplished through integrated use of ERDAS imagine (version 9.2), Arc GIS software and SPSS version 16.00. Six land use/ land cover classes were selected for the study. Results from land use/ land cover change analysis showed an increase in agriculture land and built-up area at the expense of forest land, grass land, reverine forest and bush land. The result of socioeconomic data analysis reported that agriculture, both crop and livestock productivity is declining. Among many factors, the major production constraints was directly associatedmainly with land use change. Hence, Studies of land use/ land cover dynamics can be used for land use planner, natural resource managers and policy makers to provide a management and decision process.
