ABSTRACT: Rationale: The Niger Delta, home to over 30 million people, is one of the world’s most resource-rich regions, contributing approximately 90% of Nigeria’s oil revenues. However, it faces severe environmental degradation, with oil extraction activities resulting in widespread pollution. Hydrochemical analyses have shown that levels of petroleum hydrocarbons and heavy metals in both surface and groundwater sources exceed international safety standards by up to 200% in certain areas. These pollutants, affecting water, soil, and air, directly lead to chronic health conditions, including gastrointestinal diseases, respiratory illnesses, and neurological disorders in over 60% of the population, according to local health surveys. Despite these figures, environmental degradation in the Niger Delta is rarely framed as a public health emergency, overlooking the direct health consequences and exacerbating socioeconomic inequities. The region’s governance failures and fragmented regulatory systems have compounded these problems, creating a critical need for systemic intervention. Objective: This study aims to reframe environmental degradation in the Niger Delta as a public health emergency and proposes the Integrated Environmental-Health Accountability Framework (IEHAF) to address the multi-dimensional health impacts of pollution. The goal is to establish a comprehensive model that links ecological damage to morbidity, mortality, and socioeconomic hardship, emphasizing interdisciplinary research and policy reform. Methods: We conducted a conceptual synthesis by analyzing existing data from environmental epidemiology, hydrochemistry, biodiversity loss, and health systems research to develop the IEHAF framework. This synthesis was based on a review of over 150 peer-reviewed studies, government reports, and community health surveys. We focused on three domains: 1) Environmental Toxicity and Ecological Collapse, 2) Human Exposure, Vulnerability, and Adaptation, and 3) Institutional Accountability and Policy Inertia. The framework provides an analysis of how multi-pollutant exposure leads to health inequities and long-term socioeconomic consequences, supported by empirical data on pollutant concentrations and health outcomes in the Niger Delta. Results: The IEHAF framework reveals that pollution is not only an environmental issue but also a central determinant of health inequity. By integrating environmental, health, and economic systems, it provides a holistic view of the long-term effects of extractive practices. The framework identifies how institutional inertia and policy fragmentation have deepened the crisis, resulting in intergenerational poverty and exacerbating health disparities. Conclusions: Reframing environmental degradation as a public health emergency is essential to shift policy responses from reactive to proactive. IEHAF offers a structured approach to integrate environmental governance, health surveillance, and social protection, which are critical for sustainable development in the region. Recommendations: Policymakers should adopt IEHAF in regulatory frameworks, ensure health outcomes are integrated into extractive licensing, and mandate systematic health screenings for affected communities. Researchers should focus on long-term evaluations of IEHAF, while civil society must advocate for community-led environmental monitoring and corporate accountability. Health Statement: Chronic exposure to pollutants in the Niger Delta leads to long-term health burdens, including gastrointestinal disorders, respiratory diseases, and neurological damage. IEHAF stresses the need for early intervention, health surveillance, and integrated policies to protect vulnerable populations.
