Spatial Analysis of Land use Change and Land Degradation

Landuse and landcover change is taken as a serious §problem in changing the environment, which in turn, §could lead to global climatic change and food §security. This change could be the result of §intricate interactions of socio economic and §biophysical situation like economic, technological §advancement, demography, and etc. This paper §examines the changes in land use-cover types in the §degraded environment of eastern Ethiopia over the §last 20 years, and how such changes have influenced §agricultural, local lakes and livelihoods §sustainability, especially in the Alemaya district. §Changes of land use-cover were measured through §satellite image interpretations, while local §perceptions and description of change were addressed §through household interviews and field observations. §The paternal analysis of the study using GIS and §remote sensing technique, will be important §indicator and guideline for sustainable resource §utilization and management, which provides a basis §for conservation and planning. Moreover, the §methodology and approcahes used in the study will §give a guide line for other researchers, who have §similar interests.
