dc.description.abstract	Land suitability evaluation is the base for land use planning and land management to enhance the sustainable use of land resources. Suitability evaluation for tef, maize and grass pea cultivation in r~fed agriculture was studied through a qualitative process of matching land charaC(teristics with crops requirements based on maximum limitation system. The present study ~ initiated with the main objectives of creating the digital elevation model, I identifying and mapping the major soils and LULC, classifying the watershed into land mapping units and finally producing suitability maps of the selected crops, which are c6ltivated in the Oebre Mewi watershed in the Amhara Region. The major variables used in this study include topography, climate, soil and LULC. Data of spatial vector and raster as well as the attribute of the major variables were collected from QuickBird2 satellite imagery, topographic sh~et, field observation and laboratory results. ArcInfo GIS 9.2 version was intensively used through the study. Most of the land units of the study area were found to be moderately suital?le for tef, the low lying land units highly suitable for grass pea and the well drained land units were moderately to marginally suitable for maize cultivation at a low level input use. While doing all these, the GIS-database was established and set in with a variety of datasets that can be easily update and enables to produce various types of maps and information about the Debre Mewi watershed. Thus, the study has showed GIS and RS techniques are powerful tools to integrate various data layers and to assess the potentials of land resources for scientific land use planning, decision making and resource management.	en_US
