The key industries of Aguadulce were salt and sugarcane. Due to Aguadulce's proximity to the sea, salt is easily obtained there and sugarcane grows best in tropical climates.

The salt industry in Aguadulce dates back to the early colonial period when Spanish settlers first established salt mines in the region. These salt mines became a major source of income for the area, as salt was a valuable commodity used for preserving food and salting meat.

Sugarcane cultivation also played a crucial role in the economy of Aguadulce. The fertile soil and tropical climate of the region provided ideal conditions for growing sugarcane, which was in high demand for sugar production. The sugarcane industry thrived in Aguadulce, with many plantations producing large quantities of sugar for export.

Over time, these key industries helped Aguadulce grow and prosper, contributing to its economic development and shaping its identity as a center for salt and sugarcane production. Today, while other industries have emerged in the region, salt and sugarcane remain important pillars of Aguadulce's economy and heritage.
