Urban Asset Exposure Assessment in Nigeria

The GDA Urban Sustainability consortium has supported the World Bank on the “Nigeria West Africa Coastal Areas (WACA) Multi-Sector Resilience Plan” project in Warri City, Nigeria, to improve risk assessment and enhance the resilience of urban areas. Coastal communities in West Africa are increasingly threatened by climate change, resulting in rising sea levels and more frequent extreme weather events such as record rainfall causing flooding, threatening their safety, well-being, and economic development. In addition to flooding, these coastal areas are also facing ground deformation, which occurs when the ground sinks due to factors such as soil subsidence and erosion. This, coupled with increasing population density and rapid urbanisation, is putting even more pressure on the already vulnerable coastal zones.

To address these challenges, the project has developed a comprehensive Land Use/Land Cover map of Warri, which provides essential information for assessing and managing risks in urban areas. Moreover, the consortium is currently developing a new application that will help the local authorities to assess those risks in urban areas. The application combines a range of different types of information coming from satellite imagery and shows which areas are most likely to be affected by hazards such as flooding or ground displacement.
