Climate, health, and living condition crises in the expanding informal settlements and slums of South-West Nigeria: a case report of Ogun and Oyo states
The rapid growth of informal settlements in southwestern Nigeria, particularly along the Lagos–Ogun–Oyo corridor, has created serious health and environmental challenges. Many residents lack safe housing, clean water, proper sanitation, and protection from climate-related hazards such as flooding and extreme heat. These conditions increase the risk of respiratory and waterborne diseases.
Although efforts have been made to address these problems, limited funding, weak enforcement, and poor coordination remain major barriers. A coordinated approach involving government, NGOs, and local communities is needed. Community participation, better urban planning, financial support, improved basic services, and climate resilience programmes can help create healthier, safer, and more sustainable communities.
