Cruise tourism is an important and expanding global industry. The growth of this sector,coupled with the continuous development of larger cruise ships, creates demands for new marine infrastructure. The development of these marine infrastructures takes place at the intersection of global cruise tourism, dredging and financial networks, and local social economic and civil society networks. In this paper we analyse how the interaction of these global and local networks influences ecosystem based design in marine infrastructure development, taking the Falmouth cruise terminal in Jamaica as case study. Based on this analysis of global and local networks four conditions are identified that enable and stimulate ecosystem based design of marine infrastructures: a shared (discursive) goal connecting global and local actors; brokers that connect different networks; the availability of adequate resources; and an environmental discourse that is materialized in standards and legislation.
