  land management strategies based on the identified dominant factors. A gap in this study involves the challenge of accurately capturing the dynamic temporal evolution of gully systems and the complex, non-linear interactions between numerous contributing factors. concluded included targeted that a (land use changes, poor drainage) Jackie (2024) meticulously explored the influence of human activity and environmental factors on gully erosion. The specific study area was not detailed, but the research design involved assessing correlations between various human activities and environmental conditions (rainfall, soil type) with gully technique of analysis focused on development. The demonstrating these interrelationships. Findings typically highlighted those unregulated human activities, such as deforestation and improper land management, significantly exacerbate natural predispositions like heavy rainfall and erodible soils, leading to accelerated gully expansion. The author concluded that gully erosion is a complex geomorphic process driven by a synergistic interplay of both sets of integrated factors. Recommendations emphasized on approaches for control, promoting sustainable land use and robust environmental policies. A gap in the study was the lack of in-depth quantitative modeling of factor interactions or detailed, multi-temporal analysis of specific gully evolutions. Obiorah et al. (2025) identified gully erosion as a serious threat to development in Southeastern Nigeria. Their study area, Southeastern Nigeria, is notoriously prone to severe gully formation. Their findings conclusively highlighted that gully erosion is overwhelmingly caused by a complex interplay of natural factors, including intense rainfall, highly erodible sandy soils, and challenging underlying geology. These natural predispositions are severely exacerbated by pervasive anthropogenic activities such as extensive deforestation for urban expansion and agriculture, rapid and unplanned urbanization, the construction of inadequate or poorly maintained drainage systems, and unsustainable agricultural practices. They concluded that the escalating gully crisis in Southeastern Nigeria is a direct result of the 24 | P a g e for and calls include human-induced synergistic interaction between these geological and climatic vulnerabilities land profound degradation. The recommendations stemming from their integrated watershed assessment management, large-scale afforestation programs, more rigorous urban planning, and robust enforcement of environmental policies.
