A Case Study: Abuja, Nigeria - Increased Flooding and Extreme Rainfall.
One major climate change–induced impact affecting Abuja is increased flooding due to more intense and unpredictable rainfall. In recent years, heavy downpours have overwhelmed drainage systems, leading to flash floods in areas such as Kubwa, Gwagwalada, Lugbe, and parts of the city center.
This presents serious challenges for community members and infrastructure. Flooding damages homes and roads, disrupts transportation, and increases the risk of waterborne diseases. Informal settlements and low-income communities are especially vulnerable, as they are often located in flood-prone areas with poor drainage. It also affects livelihoods, as small businesses and daily economic activities are frequently interrupted.
In response, there have been government and community-level adaptations. The Federal Capital Territory Administration has carried out drainage desilting, road rehabilitation, and demolition of structures blocking waterways. Public awareness campaigns emphasise on proper waste disposal to prevent blocked drains. At the community and individual level, residents are raising building foundations, clearing local drainage channels, and adjusting construction practices to better cope with heavy rainfall.
