Abstract

Anthropogenic activities significantly modify the River Tungu and Nithi sub-catchment, influencing biodiversity and ecological balance. This prompts a need for a thorough understanding of their effects for effective conservation efforts.  This study aims to map the influence of anthropogenic activities on land use change by integrating remote sensing with non-parametric statistical tests within the Tungu-Nithi sub-watershed. This research employs the meta-ecosystem perspective theory as its conceptual basis and utilizes mixed-methods research design. The results showed that vegetation cover and settlements increased by 19.1% and 6.7%, respectively. Conversely, there was a decrease in bare land, road networks, river area, and other land uses by 6.0%, 12.5%, 2.2%, and 5.8%, respectively. The chi-square test revealed a significant influence of anthropogenic factors on land use change, with a p-value of 0.001. The government needs to develop an integrated land use plan and strengthen collaboration to raise public awareness and encourage sustainable land use practices through environmental education.
