Logistics network and externalities for short sea transport: An analysis of horticultural exports from southeast Spain

This paper discusses the benefits of using short sea shipping in intermodal transport for fruit and vegetables. Multi-Criteria Decision Making techniques are applied to determine optimal allocation between land and intermodal transport, including environmental externalities. A sensitivity analysis is also carried out to monitor changing priorities among decision-makers (exporters) so as to encourage a modal shift. The results reveal savings in intermodal transport costs and a slight reduction in externalities with respect to land transport. However, the exporter must assume an increased delivery time of goods. At present, this situation is far from a reality, highlighting how inherently complicated it is to change the modes of transport.

► It is shown the difficulty of the change to intermodal transport for perishable products.
► Cost internalisation policies (externalities) would have no effect on modal shift.
► It is necessary to change exporters' perceptions and provide incentives for the use of shipping.
