The local natural resources contributed to the current economic structure of the municipality, with agriculture (especially fruit and wine production), fishing, light industry and, later, tourism influencing the activities of the region. The fishing industry (in the communities of Ferragudo, Benagil, Carvoeiro and Senhora da Rocha), vineyards, and the traditional products of irrigated agriculture were the principal sources of wealth for the area until the 1970s. Driven by the abundance of fish, the canning and conserve industry at the beginning of the 20th century was responsible for an economic boom, that brought a general prosperity and wealth to the region.
