Evaluating the Impact of the Port Reform Act on Operational Efficiency at Nigerian Seaports

Nigeria's 2006 Port Reform, which converted publicly operated ports to a landlord model with private terminal operators, represented the most significant structural transformation of the country's maritime sector in decades. This study evaluates the impact of the Port Reform Act on operational efficiency across Nigerian seaports, addressing a gap in longitudinal empirical assessment of the reform's outcomes. A difference-in-differences analytical design is employed, using pre- and post-reform operational data from four major ports (Apapa, Tin Can Island, Onne, and Rivers Port) covering the period 2000 to 2024. Efficiency indicators assessed include vessel turnaround time, cargo throughput, terminal equipment productivity, and import container dwell time. Secondary data from the Nigerian Ports Authority Annual Reports, World Bank port logistics surveys, and structured interviews with 30 port industry professionals are combined for triangulation. Results show that vessel turnaround time improved significantly in the decade following reform, averaging a 31 percent reduction by 2015, but efficiency gains have plateaued and partially reversed since 2018 due to equipment depreciation, infrastructure congestion, and inadequate post-concession regulatory oversight. Dwell times remain high relative to global benchmarks, pointing to persistent customs and multi-agency clearance constraints unaddressed by the structural reform. The study finds that the reform literature has over-attributed efficiency improvements to private terminal operation while under-examining the regulatory and infrastructure complementarities required for sustained performance.
