Ocean acidification, driven by anthropogenic carbon dioxide (CO₂) emissions, poses a severe threat to coral reef ecosystems worldwide, with significant implications for small island nations like Niue. This article examines the specific impacts of ocean acidification on Niue’s coral reefs, which are vital to the island’s biodiversity, economy, and cultural heritage. Through a situational analysis of Niue’s reefs and a review of global literature, the study highlights the chemical processes of acidification, its ecological consequences, and the socio-economic ramifications for Niue’s communities. The paper further explores the role of intergovernmental organizations and international treaties in addressing this crisis, emphasizing the need for coordinated global action. Recommendations are provided to mitigate acidification impacts through local conservation efforts, regional collaboration, and international policy advocacy. This article underscores the urgency of integrating ocean acidification into global climate agendas to protect vulnerable ecosystems like Niue’s coral reefs.
