Abstract
Sustainable land management (SLM) is one of the major issues of concern to Nigerian policy makers due to persistent degradation of land. This study applied the fuzzy set method to compute composite indicator of unsustainable land use (IULU) from selected plot-level indicators. Results show that average IULU is 0.43 with 41.48 percent of the farms having higher values. Trends in vegetation covers, vigor of crop growth, crop yields, organic matter contents and type of seeds grown have highest contributions to IULU. Also, estimated parameters with Tobit regression show that education, household size, access to credit, access to extension and per capita farm income significantly reduced IULU, while farming experience, erosion problem and inadequate land problem increased it (p<0.10). The study noted that efforts to promote soil conservation technologies through extension workers and ensuring availability of credits, among others, will go a very long way in addressing land degradation.
