Climate Change and Flooding: Rising Waters of Nyangara Marsh Devastate Uvira

Context

The city of Uvira, in South Kivu, is once again grappling with severe flooding caused by the rising waters of Nyangara Marsh. What was once a seasonal challenge has now evolved into a recurring crisis, intensified by climate change. Increasingly heavy rainfall, unpredictable weather patterns, and rising water levels in Lake Tanganyika and the Ruzizi River are compounding the situation, leaving communities more vulnerable each year.

Widespread Infrastructure Damage

The floods have significantly disrupted critical infrastructure across the city:

• Roads: National Road No. 30, a key route linking Uvira to the Burundi border, has been submerged, halting mobility and delaying ongoing rehabilitation efforts.
• Schools: Several schools in Kavimvira are underwater, forcing closures and interrupting education for many children.
• Homes: Entire neighborhoods—including Kalimabenge, Kasenga/Muramvya, Kilomoni, Kavimvira, and Kala—are heavily affected, with families losing homes and essential belongings.
• Hotels: Even hotels have not been spared, highlighting the widespread economic impact of the flood. 

Humanitarian and Safety Risks

Beyond infrastructure damage, the flooding poses serious risks to human life and safety:

• Residents are struggling to navigate flooded areas, often relying on canoes for movement.
• The presence of hippos in inundated zones has introduced an unusual but dangerous wildlife threat.
• Many families are being forced to relocate to safer areas, underscoring the urgency of effective disaster preparedness and response systems.

A Pattern of Recurring Crisis

Flooding in Uvira is not new—but it is becoming more severe and frequent. In April 2020, the Mulongwe River overflow led to at least 40 deaths and displaced approximately 75,000 people. Today, similar patterns are re-emerging, with even greater intensity. Climate change is a key driver behind this escalation. Low-lying areas such as Kalimabenge, Kasenga/Muramvya, Kilomoni, and Kavimvira are increasingly exposed, with each rainy season bringing heightened risks and fewer recovery windows.

Conclusion: From Crisis to Urgent Action

The rising waters of Nyangara Marsh are a reminder of the real and immediate impacts of climate change on vulnerable communities. This is no longer a distant threat—it is a present and escalating reality. To address this crisis, urgent and coordinated action is needed:

• Invest in climate-resilient infrastructure, including drainage systems and protective embankments.
• Establish early warning systems and clear evacuation plans to protect lives.
• Strengthen community awareness, including education on emerging risks such as wildlife displacement during floods.
