How did containerization change the land area needed at port berths?

The advent of containerization has significantly increased the land area required at port berths. While containerization has allowed for a reduction in the total number of individual berths needed, it has necessitated a substantial expansion of the land associated with each remaining berth to accommodate complex, high-capacity port facilities.

In the context of civil engineering for harbors and sea works, a requirement of approximately 20 acres (8 hectares) of land per berth is considered a reasonable standard for modern container operations. This space is essential for the storage, weight-handling equipment, and necessary links to land transportation required to realize the economic potential of containerized shipping.12
