Suitability Analysis for Ginger Production in Song Local Government Area, Adamawa State, Nigeria

Abstract

Identification of land with high productivity and net profit, while minimizing input requirements, is crucial for enhancing agricultural production and promoting sustainable development in Nigeria. This study aimed to assess the suitability of land for ginger cultivation in Song LGA, utilizing geographic information system (GIS), remote sensing, and the analytic hierarchy process (AHP). Key criteria considered for the suitability analysis included slope, land use land cover, nitrogen, phosphorus, potassium, and soil texture. Standardization of all criteria was performed, and AHP facilitated the determination of weightage for each criterion through pairwise comparison. The suitability map for ginger production was generated using weighted overlay techniques. The findings revealed that approximately 75% of the study area is marginally suitable, while 25% is moderately suitable for ginger cultivation. However, it is important to note that future research should focus on acquiring more precise and accurate spatial data related to soil properties, topography, and climate. By incorporating such data, it is anticipated that a more refined and reliable land suitability map for ginger production can be developed. This study highlights the potential for using GIS, remote sensing, and AHP as valuable tools for assessing land suitability for ginger cultivation. The generated suitability map can serve as a valuable resource for policymakers, land managers, and farmers seeking to make informed decisions regarding ginger production. Further investigations should aim to refine the methodology and expand the data sources to enhance the accuracy and applicability of land suitability assessments for ginger cultivation.
