Coastal Land Use: Socio-ecological (D)evolution of Saltscapes in Portugal

Since the mid-1990s, traditional marine salt (TMS) production has seen a renaissance, driven largely by the revaluation of fleur de sel (FoS) in the market—a product that previously lacked commercial appeal. Its rise as a premium commodity in global niche markets has encouraged producers to reinvest in this ancient practice, deeply rooted in coastal socio-ecological systems. This study examines not only the diversification of salt-based products but also the emergence of cultural ecosystem services, particularly those related to tourism. By situating TMS and FoS within broader transformations in land use and socio-ecological system dynamics, the research highlights their role in sustaining traditional knowledge, local economies, and the integrity of the coastal landscape.
