The Influence of Human Activity and Environmental Factors on Gully Erosion

Arikpo Jacintha Jackie

Gully erosion, far from confined to specific terrains like badlands or mountainous areas, stands as a global issuecontributing significantly to land degradation across various soil types susceptible to crusting or piping. Evenafter initial triggers cease, formed gullies can persistently generate sediment. This study delves into themultifaceted influences of geology, climate, slope morphology, vegetation, human impact, and soil properties ongully development and broader soil erosion. Drawing from empirical examples globally and locally, it underscoresthe pivotal role of local soil characteristics in propagating erosion, particularly the gully variant. Anthropogenicfactors, especially land use practices and their impact on vegetation, weigh heavily. Rampant deforestation coupledwith insufficient re-vegetation or afforestation initiatives have exacerbated the looming erosion threats,contributing to catastrophic consequences. Despite the effectiveness of various strategies in preventing andaddressing gully erosion, their sustained implementation on a large scale remains elusive. Thus, research prioritiesmust encompass sub-surface flow erosion mechanisms, predictive models, and the intricate dynamics influencingfarmers' adoption or rejection of conservation strategies. To combat soil erosion comprehensively, a holisticapproach to soil conservation becomes imperative. This entails employing hydrological or bioenvironmentalprocesses to regulate overland flow and curb excessive runoff. Prioritizing these aspects can inform more robuststrategies for soil conservation, mitigating the pervasive impact of erosion on our lands.Keywords: Influence, Human, Activity, Environmental Factors and Gully Erosion
