The aim of this dissertation is to apply the DEA and SFA methods to
evaluate efficiencies of 6 major ports out of 12 in total, in West Africa
and to understand if these ports can become the main hubs of container
transport to African inland in the future and how they can evolve through
the time. The selection of 6 West African ports based on their container
throughput levels which is over 100,000 TEU’s per year. The DEA and
SFA methods were used to determine their relative efficiencies and their
efficiencies over time through window analysis for the period 2006-
2012.The DEA and SFA methods were applied to a number of inputs
such as total quay length, total terminal area, number of quayside cranes,
number of gantry cranes and number of reach stackers and a single output
which is the total TEU’s throughput. It was determined via DEA method
that the Port of Tema in Ghana with the Port of Lomé in Togo was the
most efficient West African ports under study. On the Contrary the Port
of Cotonou in Benin was found to be the least efficient port obtaining the
lowest average efficiency rating over the period 2006-2012 via DEA
method.In most cases, West African ports could be said to exhibit high
levels of efficiency considering that four out of six ports had an average
efficiency score of 76% or higher for the period under study. Through
SFA method the results were much different from DEA, as only three
ports had average efficiency scores over 76%. Port of Dakar was the most
efficient of West African ports and Port of Lagos was determined as the
most inefficient port.
