Zanzibar is increasingly experiencing extreme weather events, including intense rainfall, flooding, and
coastal erosion, largely driven by climate change and rapid urbanization.
Recent Extreme Weather Events
- Heavy Rainfall and Flooding: In late 2023 and early 2024, East
Africa, including Zanzibar, faced catastrophic rains that led to widespread flooding. These events
resulted in significant loss of life, displacement of thousands, and destruction of infrastructure and
crops. Scientists have attributed these intensified rains to climate change, which has doubled their
likelihood and increased their intensity by 5%.
- Coastal Erosion and Saltwater Intrusion: Rising sea levels and
extreme weather are threatening Zanzibar's coastal communities. Areas like Stone Town are experiencing
beach erosion and damage to cultural heritage sites. Saltwater intrusion is also affecting freshwater
resources and agricultural productivity.
- Marine Economy at Risk: Zanzibar's economy heavily relies on
marine resources, including fishing and tourism. However, climate change impacts such as coral reef
destruction, declining fish stocks, and saltwater intrusion are jeopardizing these sectors, affecting
the livelihoods of local communities.
Government and Community Responses
- Infrastructure Improvements: The government is investing in
infrastructure projects like the Jangwani Bridge to mitigate flooding and improve drainage systems in
urban areas.
- Climate-Smart Agriculture: Initiatives are being implemented to
promote climate-resilient farming practices, including water harvesting, soil conservation, and the
use of drought-resistant crops .
- Community Engagement: Community-driven solutions are being
emphasized, with local populations actively participating in disaster risk reduction and climate
adaptation efforts.
Outlook
The frequency and severity of extreme weather events in Zanzibar are expected to increase due to
ongoing climate change. Continued adaptation and resilience-building efforts are crucial to safeguard
the island's communities and economy.
