Climate Change Variables and Net-Zero Pathways: Building Coastal Resilience in West Africa Through Integrated Strategies
摘要
Coastal West Africa faces escalating climate threats, including sea level rise, extreme weather events, and ecosystem degradation, despite contributing less than 2% of global greenhouse gas emissions. This imbalance underscores the region’s acute vulnerability and the need for net-zero pathways that integrate emissions reduction with resilience-building. This study examines the convergence of climate change variables and net-zero strategies to bolster coastal resilience in West Africa. Employing a mixed-methods approach, the research combines narrative synthesis with climate data analysis using NASA Giovanni, an online satellite platform, to assess recent (2022–2024) climate indicators: sea surface temperature (SST), sea level pressure (SLP), particulate organic carbon (POC), precipitation patterns, and calcite concentration. Analysis reveals persistently elevated SSTs exceeding 27 °C along the Gulf of Guinea, exacerbating coral degradation and fisheries decline, diminishing both livelihoods and blue carbon potential. Lower sea level pressure values along southern coastal zones coincide with areas of increased flooding susceptibility, while localized POC hotspots, particularly from Nigeria to Senegal, signal productive blue carbon ecosystems but also raise concerns about eutrophication. Heavy precipitation, notably in Nigeria’s southern states and the Liberia-Guinea belt, amplifies flood and sediment runoff risks, accelerating land degradation and undermining carbon sequestration capacity. Additionally, reduced calcite concentrations reflect growing acidification pressures, threatening calcifying organisms and marine biodiversity. These stressors undermine carbon sinks and coastal stability, threatening net-zero progress. Integrated nature-based solutions, like mangrove restoration, are vital, but financing, governance, and data gaps persist. A resilience-focused transition is crucial, prioritizing blue carbon, data systems, and adaptive governance.
