Crops grow best in locations where conditions meet their growth requirements like elevation, slope, aspect, soil, land cover, and many other climatic factors. So, a land suitability analysis (LSA) of Malus domesticain West Kameng district of Arunachal Pradesh, India, was attempted using an integrated approach of Analytical Hierarchy Process (AHP), Weighted Overlay Analysis (WOA), and Geographic Information System (GIS). Based on literature survey and farmer’s opinion, the elevation, slope, aspect, annual temperature, rainfall, soil type, soil drainage, and land use/land cover (LULC) criteria were considered important for M. domesticacultivation in the area. AHP method was applied to score the criteria using available literature and interview with the local experts. Elevation scored the highest weight of 0.321 followed by temperature with 0.243. The weights of other criteria in parenthesis are slope and LULC 0.13 each, aspect and rainfall 0.060 each, and soil type and soil drainage 0.028 each. The results showed that 8.12% (392.98 km2) of the study area is highly suitable for M. domesticacultivation while 20.59% (996.08 km2) is not suitable. Rest of the area constituting 71.28% (3448.35 km2) was found moderately or marginally suitable. However, the study reveals that the current suitable areas are mostly underutilized. Thus, greater efforts to increase the area under crop might ensure higher productivity in the future. The methods and techniques used in this study can be efficiently replicated to assess the land suitability of other important horticultural and agricultural crops.
