Minderhoud, Leon Hause, and 5 more This is a preprint; it has not been peer reviewed by a journal. https://doi.org/ 10.21203/rs.3.rs-8922509/v1 This work is licensed under a CC BY 4.0 License Status: Posted Version 1 posted You are reading this latest preprint version Abstract Land subsidence is a threat to environmental sustainability and can pose greater dangers with a proportionate rise in bordering sea levels. Nigerian low-lying coastal region and the various economic activities around the coast are vulnerable to rising sea level because of global warming. However, no existing study has examined sea-level rise combined with land subsidence. This study reviews available literature on land subsidence and consequential relative sea-level rise along Nigerian coastlines and identifies research gaps. Subsidence occurs, at least, in four Nigerian coastal cities – Lagos, Port Harcourt, Uyo, and Warri. The highest observed subsidence (up to 520 mm/year) is found in the Harcourt area, which is likely due to continued groundwater pumping and oil and gas extraction.
