  • Abstract

    Sea level rise poses significant threats to coastal nations globally, particularly those with extensive economic exclusive zones (EEZ) and ‎vulnerable coastal infrastructures like Nigeria. This study assesses sea level rise along Nigeria’s EEZ using NASA’s advanced sea level rise ‎tools and satellite data. The research integrates NASA’s altimeter satellite data and digital elevation models (DEMs) to quantify historical ‎trends and project future sea level rise impacts along the Nigerian coastline. Findings indicate the Rate of Sea Level Rise has increased by ‎‎12cm Sea level rise 1993-2023), with 18cm Sea level rise projected for 2050. This indicates a consistent upward trend in sea level, with an ‎average rise rate exceeding global averages due to regional variations. This rise threatens Nigeria’s coastal ecosystems, economic activities ‎, including the oil and shipping industries, and coastal settlements. Strategic adaptation and mitigation planning based on satellite data and predictive modelling are crucial to safeguarding Nigeria’s coastal and marine assets‎.
