Beira, a coastal city in central Mozambique, faces significant risks from sea level rise (SLR). Located below sea level, the city is highly vulnerable to flooding, especially during extreme weather events. Beira is not only a major port but also a hub for trade and industry, which makes its protection vital for the country’s economy. However, SLR exacerbates the city’s vulnerability, leading to more frequent and intense flooding, particularly in low-lying areas.
In addition to flooding, saltwater intrusion is a growing concern, affecting freshwater supplies and agriculture. This further jeopardizes food security and livelihoods, especially for communities living near the coast. The impacts of SLR are compounded by land subsidence, exacerbated by human activities such as groundwater extraction.
Efforts to protect the city include flood barriers and other infrastructure projects, but these solutions may not be sufficient given the rapid pace of climate change and ongoing SLR. With increased frequency of cyclones, like Cyclone Idai in 2019, Beira’s resilience is increasingly tested. Adaptation strategies, including the restoration of natural barriers such as mangroves, are crucial for the city’s long-term survival. However, the situation remains dire, and more proactive, large-scale measures are needed to ensure Beira’s future against rising seas.
