This work interrogates the operational integrity of Nigeria’s Environmental Impact Assessment Act, moving beyond doctrinal analysis to expose the structural disconnect between regulatory design and real-world compliance. While the Act was conceived as a cornerstone of environmental governance, its execution has remained fragmented, opaque, and weakly enforced—undermining its capacity to safeguard ecological systems amid rapid infrastructure expansion. The study delivers a system-level re-engineering of the EIA process through a rigorously defined, algorithmic nine-stage workflow. Unlike the conventional linear model, this architecture embeds continuous feedback loops, enforces digitally auditable public participation checkpoints, and institutionalises post-approval monitoring as a non-optional control layer. The result is a transition from static compliance to adaptive, verifiable governance. Empirically, the research constructs the first sector-disaggregated EIA inventory for Akwa Ibom State, mapping 50 mandatory-list projects across 17 sectors. The analysis reveals a skewed development profile dominated by infrastructure (18%), housing (14%), and petroleum (10%), with critical transport nodes such as ports and airports minimally represented (2% each). These patterns expose underlying policy priorities and potential blind spots in environmental risk distribution. A comparative benchmark between Nigeria’s prevailing EIA framework and the proposed algorithmic model identifies three systemic failure points: non-transparent screening mechanisms, inadequate scoping disclosure, and the near absence of enforceable post-decision auditing. Addressing these gaps, the study advances a reproducible compliance-engineering template designed for scalability across jurisdictions. Positioned at the intersection of environmental governance, regulatory technology, and sustainable development, this work contributes a policy-ready reform package aligned with the United Nations 2030 Sustainable Development Agenda. It offers both a diagnostic and a deployable solution—bridging legal intent with operational accountability in emerging economies.
