The Mwambashi River disaster of February 2025, caused by the collapse of a tailings dam at a Chinese-owned mine, released over 50 million liters of acidic effluent into the river system. The immediate effects included mass fish kills, farmland destruction, and drinking water contamination. The long-term implications are serious, affecting national food security, biodiversity, and public health. The evacuation of U.S. citizens from the area underscored the global importance of the disaster and revealed some challenges in Zambia's environmental governance.This study uses a comparative case study approach to analyse the Mwambashi Acid and Toxic spill alongside similar international events like Love Canal (USA), Bhopal (India), Chernobyl (Ukraine), Minamata (Japan), Exxon Valdez (USA), Côte d’Ivoire (2006), and the Flint water crisis (USA). The paper examines immediate response measures, long-term remediation tactics, and governance outcomes across these cases by reviewing peer-reviewed literature, reports from international organizations, media accounts, and policy analyses. The findings indicate that rapid evacuation, medical monitoring, and containment strategies are vital in reducing immediate harm. Long-term success relies on enforceable liability frameworks, ongoing ecological rehabilitation, and clear public engagement. Lessons drawn from these comparisons show that weak accountability in cases like Côte d’Ivoire and Dzerzhinsk leads to lasting health and ecological issues. In contrast, the United States and Japan's strong liability and monitoring systems have propelled institutional reforms. For Zambia, the Mwambashi disaster is both a crisis and a chance for improvement. Recommendations for policy changes include enhancing regulatory capacity, establishing liability and compensation mechanisms, restoring water safety and ecosystem health, and increasing community involvement in recovery plans. Taking these steps could turn the Mwambashi spill from a serious failure into a critical moment for reform in environmental governance and sustainable resource management.
