Abstract

Land suitability analysis using Geographic Information Systems (GIS) has emerged as a critical tool for sustainable soil management and agricultural planning. This study presents a comprehensive framework for evaluating land suitability using multi-criteria decision analysis (MCDA) integrated with GIS technology. The research utilized digital elevation models, soil surveys, climatic data, and satellite imagery to assess land capability across a 15,000 hectare study area. Key parameters including slope gradient, soil texture, pH levels, organic matter content, drainage conditions, and erosion susceptibility were analyzed using weighted overlay techniques. Results demonstrated that 32% of the study area was highly suitable for sustainable agricultural practices, 45% showed moderate suitability, and 23% required significant soil management interventions. The GIS-based approach successfully identified priority areas for soil conservation, optimal crop selection zones, and regions requiring targeted management strategies. This methodology provides decision-makers with spatially explicit information for implementing sustainable land use policies, reducing soil degradation, and optimizing agricultural productivity while maintaining environmental integrity.
