ENVIRONMENTAL IMPACT OF SOIL DREDGING: A CASE STUDY OF IKOT EBIERE RIVER, ONAH.
Abstract
This study examines the environmental and socioeconomic effects of soil dredging on the Ikot Ebiere River, Onah. Field data, laboratory analyses, and interviews reveal significant impacts on water quality, sediment composition, biodiversity, and local livelihoods. Findings include elevated turbidity, heavy metal contamination, and reduced dissolved oxygen, leading to habitat degradation and biodiversity loss. Dredging disrupts sediment transport, causing downstream sedimentation and upstream erosion. Socioeconomic effects include declining fish yields, reduced agricultural productivity, and increased poverty. Weak regulatory enforcement exacerbates these issues. Recommendations emphasize sustainable dredging practices, stricter policies, and community involvement to mitigate adverse effects.
