Change in environmental stability and the use of resources on small islands: The case of Formentera, Balearic Islands, Spain

Abstract

Since the beginning of the 1960s, mass tourism has been the most important menace to the environmental stability of fragile and vulnerable Mediterranean microinsular systems. The socioeconomic changes introduced by tourism have produced important variations in the use of resources, including land. The result usually has been an increase in the level of artificiality of the territory, particularly in coastal areas. The intensity and frequency of change in the use of resources and the induced changes in the level of artificiality may be used as an estimation of environmental stability. The northern area of Formentera, Balearic islands, Spain, being the most environmentally important area of the island and simultaneously the most threatened by mass tourism development, has been chosen as a study case. Forty types of vegetation and land use have been estimated and mapped in the area. The stability level of each land use type has been estimated, before and after the development of tourism, and the main environmental processes have been identified. An attempt is made to predict some future trends and their variations.
