Traditional hinterlands typically fulfilled two key roles related to their ports:
-
Supply Role: Hinterlands provided the raw materials and agricultural products needed by the port cities. They served as the source of goods that were transported to ports for processing, manufacturing, or export.
-
Market Role: Conversely, hinterlands acted as a market for the finished goods and products that originated from the port. The port facilitated the distribution of goods to surrounding regions, providing access to imported products as well as exports.
Together, these roles created a symbiotic relationship between the ports and their hinterlands, supporting trade and economic activities in both areas.
