Tea plantation faces wider range of soil fertility issues, this issue include physical,and biologicalissues interactandincludelossof, topsoil due to erosion, acidity, salinity, and deterioration of other physical soilproperties. The aim of this research project was to develop the potential sites map for tea plantation in Twumba sector, Karongi district. Analytic hierarchy processes with a combination of Geographical information System (GIS) techniques were used to analyze eight different criteria which were selected. To achieve objectives of this study, Landsat8 was used in land use/ land cover estimation in detail to assess their spatial and temporal variability within the area. Reclassification and weighted overlay were used to analyze the important criteria in order to identify the potential sites mapping for tea plantation in Twumbasector. Rainfall, soil PH, soil texture, soil depth, slope, elevation, drainage, and land use land cover were selected as important criteria to identify the potential sites for tea plantation in Twumba sector. 53.6% (532.2 km2 ) of the study area be high suitable for Tea plantation,30.4% (301.9 km2 ) Thisstudyhasidentified that 53.6% (532.2 km2 ) of the study area are highly potential site for tea plantation and 30.4% (301.9 km2 )is moderately potential for teaplantation. As the results shows, the comparing of thesimulated potential landuseclassestotheexistinglandusepattern the most part of potential and moderate lands were covered by Nyungwe Park which is protected area and taken as the tourist attraction.
