Multi-criteria decision-making (MCDM) process is important for sustainable land resource planning and management. Among different MCDM techniques, the Analytical Hierarchy Process (AHP) is popular for its simplicity in use as well as it offers complex unbiased decisions. A GIS (Geographical Information System)-based AHP is essential for land-use suitability analysis. The AHP is a trusted decision-making method proved with a mathematical formula that has multi-purpose utilities. It provides an opportunity to select important alternatives among numerous factors along with proper ranking. It also maintains consistency among the factors using the sensitivity analysis. The limitations of the AHP are that the expert’s opinion may vary for the time being, and it always follows straight models. Nevertheless, the AHP could be used by scientists, land-use planners, and land policymakers for suitable land selection with a view to sustainable land management.
