In “Nodal security in the ports of Rotterdam and Antwerp” the authors explore the differences and similarities between the ports of Rotterdam and Antwerp in the way an integrated approach, the nodal approach of security, has been moulded. The authors clarify the concepts of the nodal orientation, of nodal strategies and of nodal security governance. They describe the way in which the key players in the ports of Rotterdam and Antwerp (port authorities, customs and the police) have put these concepts into practice and the governance-like structures that have evolved out of their mutual cooperation.
