Combined remote sensing and multi-criteria analysis of wetland soil potential for rice production: case study of Ogun river basin, Nigeria

摘要

This study aimed to assess the potential for rice productivity in the wetland soil of Nigeria's Ogun River basin. TOPSIS' multi-criteria analysis process, Ca-Markov model, with NDVI, NDWI, and land surface temperature from remote sensing data analyses were used to derive an efficacious wetland soil potential model for rice production. The potential for rice cultivation in the area varied from highly suitable (6.6), to moderately suitable (50.1) areas, and from marginally suitable areas (26.0) to areas that are currently unsuitable (17.3). The major barriers to rice soil suitability were topography, temperature, low fertility, and erosion hazards.
