When the River Refuses Its Old Rules: Flooding and Climate Change on the West Bank of Zambezi District
Flooding along the west bank of Zambezi District has shifted from a familiar seasonal event to a disruptive climate change impact that increasingly shapes everyday life. The Zambezi has always flooded, but recent years have brought heavier rains, longer flood durations, and unpredictable timing. These changes reflect wider climate dynamics, where intensified rainfall upstream translates into more severe flooding downstream, overwhelming both natural systems and human coping mechanisms.
The most immediate impact is on livelihoods. Subsistence farming remains the backbone of the local economy, yet floods frequently destroy crops before harvest and wash away livestock. Fishing infrastructure is damaged, and trading activities stall when floodwaters cut off access routes. For many households, a single flood season now determines whether the year ends in stability or prolonged hardship.
Infrastructure and social services suffer quietly but consistently. Roads become impassable, isolating communities from markets, schools, and health facilities. Health service delivery is disrupted, increasing vulnerability to malaria, diarrhoeal diseases, and other flood-related illnesses. Temporary displacement, overcrowding, and poor sanitation further compound these risks, turning flooding into a public health and development concern rather than a purely environmental one.
Adaptation is happening, though largely at a survival level. Families raise homes and granaries, adjust planting times, and shift to flood-tolerant crops. Communities rely on informal early warning systems and strong social networks to relocate people and assets ahead of severe floods. Government responses, mainly through disaster relief, provide short-term support but remain reactive, offering limited protection against future events.
What emerges is a community caught between resilience and exposure. The floodplain sustains livelihoods, yet climate change is altering its risks faster than adaptation efforts can keep pace. Flooding on the west bank of Zambezi District illustrates how global climate change materialises locally, demanding not just emergency responses, but long-term, locally grounded adaptation strategies that recognise the river’s power and the community’s lived realities.
