Health risk assessments of River Nyamwamba
shows that up to 2 in 10 children and 3 in 100 adults could be at risk of developing excess cancer due to prolonged exposure to contaminated water containing toxic metals.
As a result, Kasese has been reported among areas of concern for rising cancer risks linked to environmental pollution.
River Nyamwamba was once a symbol of life in Kasese, providing water, food and livelihoods to surrounding communities. Today, climate change has turned the river into a source of fear and destruction.
Glaciers on the Rwenzori Mountains, the riverโs source, have reduced by nearly 90% since 1900 due to rising temperatures. This has contributed to severe flooding that has claimed over 60 lives since 2011 and destroyed more than 25,000 homes during the 2020 floods alone.
Floodwaters also wash toxic waste from abandoned copper mines in Kilembe into the river, releasing about 744,000 tonnes of mining waste to the environment exposing nearby communities to harmful heavy metals such as copper, cobalt and serious health risks.
A long term solution requires government action to rebuild durable riverbanks, supply rainwater harvesting tanks to local communities, and support the construction of elevated homes that can withstand flooding along River Nyamwamba.
