SUMMARY:

The interactions between the abiotic and biotic elements that occur within an ecosystem provide benefits to society that correspond to ecosystem services. Defined as the variety of abiotic elements, geodiversity sustains and offers benefits to human beings through the provision of ecosystem services that can occur in different landscapes. In the context of the Brazilian semiarid region, there are landscapes with particular physical and natural characteristics that differ from the dominant environment and are called exceptional landscapes. This research aims to analyze and classify the ecosystem services provided by geodiversity in exceptional landscapes in the Brazilian semi-arid region and compare them with those offered in the surrounding area. The spatial-empirical cut-off point is four places considered to be exceptional landscapes: the plateaus of Araripe, Martins-Portalegre, João do Vale and Santana. To this end, geomorphological mapping was carried out to delimit the relief compartments. We chose to work with an identification form for abiotic ecosystem services adapted by Araújo, Diniz and Souza (2024), which groups benefits into four categories: regulation, provision, cultural and support. The degree of relevance was also assessed using the method that Araújo, Diniz and Souza (2024) adapted from Burkhard (2017). The results obtained show that geodiversity supports different types of ecosystem services that are distributed across the relief compartments of the areas studied. In Martins-Portalegre, it was observed that the plateau and the slopes, which are the exceptional landscape compartments, offer more regulation and provisioning services than the surrounding area. As for João do Vale and Santana, the data revealed that plateaus and hillsides offer more benefits in the category of regulation services. Initial results are revealing that the exceptional characteristics of landscapes of exception, conditioned by the relief, are decisive in offering benefits that are fundamental for society and sustaining biodiversity. Particularly noteworthy is the greater offer of benefits in the regulatory services category. Identifying and evaluating these services is essential if geoconservation strategies are to be developed in these areas.
