Climate Risk-Informed Coastal Planning and Risk Reduction for a Resilient Lagos

The proposed project aims to shift Lagos State from unsustainable development practices to a climate-resilient pathway. It focuses on three outputs: strengthening institutional and financial frameworks for coastal planning, implementing hybrid grey-green infrastructure for flood and storm surge protection, and supporting climate-resilient livelihoods. The project targets approximately 2.8 million direct beneficiaries, particularly in the Lagos Island, Eti-Osa, and Ibeju-Lekki Local Government Areas, with an indicative total cost of USD 130.5 million.

• Lagos State is highly vulnerable to climate hazards, specifically pluvial and fluvial flooding, storm surges, and sea level rise (SLR), which are exacerbated by low-lying topography and rapid, unregulated urban expansion into floodplains and wetlands.
• Historical land-use changes have significantly reduced wetland areas in Lagos, dropping from 33% of the total state area in 1986 to 10% in 2020, increasing the exposure of vulnerable communities to flooding.
• Future climate projections for southern Nigeria indicate sea levels could rise by up to 58 cm by 2100 under RCP4.5 and up to 84 cm under RCP8.5, with storm surges potentially reaching 5 m in height in Lagos.
• The project identifies three priority Local Government Areas (LGAs) for on-the-ground interventions based on exposure to hazards and socio-economic factors: Lagos Island, Eti-Osa, and Ibeju-Lekki.
• A central component of the proposal is the establishment of a sustainable climate resilience financing facility (CRFF) to catalyze public and private investment in climate-resilient MSMEs and nature-based solutions.
• The project proposes a hybrid approach to risk reduction, combining hard engineering (such as sea walls and groynes) with ecosystem-based adaptation (EbA) measures like mangrove and wetland restoration.
• The project aims to benefit approximately 6.3 million people in Lagos State's coastal zones, consisting of 2,834,000 direct and 3,457,000 indirect beneficiaries.
• Economic losses in Lagos due to climate change impacts are expected to reach approximately US$128.5 billion per year by 2023.
• The total indicative cost of the project is USD 130.5 million, with USD 45 million requested as a grant from the Green Climate Fund and USD 85.5 million in co-financing.
