Abstract
In 2019, community fishponds were established near two towns in Eastern Uganda by Ideal Life Vision Uganda with the support of Rotary International. The ponds are stocked with African Sharp-tooth Catfish (Clarias gariepinus) and Nile Tilapia (Oreochromis niloticus) and are used as a source of both nutritious food and income for the local communities. Unfortunately, commercial and artisan gold mining in the surrounding regions have led to high amounts of mercury pollution within the ponds, negatively impacting both fish production and overall community health, presenting a major threat to the success and functionality of the ponds and the well-being of the local communities. Using the System-Centric Threats Resilience Methodology as my research model, I explored the various human and material elements of the pond and the interconnectedness of each factor, with the goal of providing actionable recommendations to the community and organization leaders for building resilience against heavy metal pollution. My primary proposals include the need to implement mercury testing, a joint petition with other impacted groups for greater government oversight of regional mining activity, and the utilization of wetland plants, specifically bamboo, in phytoremediation- a natural process in which plants are used to stabilize or remove toxic compounds from soil and water, providing an affordable but effective method of environmental purification. This research can help guide community and project leaders in mitigating mining impacts on the ponds, restoring pond functionality, and protecting community health. The project's findings, particularly regarding phytoremediation, can also be used to inform conservation and restoration efforts within the state of Utah and in other regions impacted by pollution and environmental contamination.
