Urban development along the coastal zone involves land use changes that directly affect coastal ecosystems and services. The Bay of Cádiz, a metropolitan area in the south of Spain, is a study case in which the urban coastal occupation is clearly reflected, with the consequent loss of certain services that the ecosystems offer to the population. The research analyses urban changes in land uses and their impacts for Integrated Coastal Zone Management (ICZM) proposals.

The methodology used in the research leads with the definition of the Bay of Cádiz as a Social-Ecological System, where natural and geographical characteristics converge with those social, economic and administrative, for delimiting the study area with an integrated perspective. The study of land uses evolution in the Social-Ecological System of the Bay of Cádiz, as well as the analysis of every ecosystem and their services, allows to obtain those impacts on human well-being that happen from pressures exerted. This analysis is developed through DPSIWR method, in which human well-being is incorporated to obtain ICZM responses.

Results show that land use changes in the Bay of Cádiz involves the loss of those ecosystems that offer the most important services to the population, such as tidal saltmarshes. In this sense, management responses should be focused on the conservation of these threatened services, with the coordination and cooperation among different public administrations.
