Spatio-Temporal Dynamics of Riparian Land Use/Land Cover and its Effects on Channel Morphology Along Dasin Hausa-Jimeta Reach of River Benue in Adamawa State, Nigeria
Abstract
This study examines the spatio-temporal dynamics of riparian land use/land cover (LULC) changes and their implications for channel morphology along the Dasin Hausa–Jimeta reach of River Benue in Adamawa State, Nigeria. Multi-temporal satellite data for the years 1992, 2005, 2015, and 2025 were analyzed using geospatial techniques to quantify changes in key land use classes, including water bodies, sandbars, grassland/shrub, bare surfaces, riparian vegetation, built-up areas, and agricultural land. The results reveal a significant transformation of the riparian landscape over the 33-year period, characterized by a substantial increase in agricultural land from 40.0% to 71.9% and built-up areas from 0.8% to 3.2%. Conversely, natural vegetation types, particularly grassland/shrub and riparian vegetation, declined drastically by 22.11% and 6.94%, respectively. Sandbar expansion (+0.63%) and a reduction in water bodies (−0.36%) were also observed, indicating active geomorphological adjustments within the river channel. The findings suggest that intensified agricultural activities and human encroachment into riparian zones have accelerated soil erosion and sediment transport, leading to increased sediment deposition and channel instability. These processes have contributed to observable changes in channel morphology, including sandbar formation and potential alterations in flow regimes. The study underscores the strong linkage between land use changes and fluvial processes, highlighting the need for sustainable riparian management strategies to mitigate environmental degradation and preserve channel stability. It is recommended that riparian buffer zones be enforced and integrated land use planning be adopted to ensure the long-term sustainability of the river system.
