This work aims to evaluate the effect of beachrocks on the behavior of the coastline of Arembepe (North Coast of Bahia, Brazil), since in this locality there are two or more generations of beachrocks, located either in the nearshore, or on the beach face or in both positions, making this place a laboratory for studies of the influence of beachrocks in different locational situations. The methodology of the work consisted of 13 campaigns to survey beach profiles based on the Emery’s Method (1961), in addition to the mapping of beachrocks and coastlines from 1976 and 2022. 21 transects were also plotted to measure the displacement of the coastline between these years and calculated the respective rates and errors. The profiles were located in different situations: i) in circulation cells limited at the ends by beachrocks (profiles 1 to 3), corresponding to the southwestern section of the study area; ii) in front of a sandstone body attached to the beach face and another on the nearshore, without and with the presence of a channel between them (profiles 4 and 5, respectively), pattern that occurs in the central part of the study area; iii) on two faces of an salient with a discontinuous sandstone present in the nearshore (profiles 6 and 7), corresponding to the northeastern portion of the study area. The analysis of beach profiles 1 to 3 contributed to the understanding of sedimentary dynamics, showing seasonal changes in the direction of longshore drift and demonstrating a transport for NE between April and September, and for SO between October and March. This dynamic can be extrapolated to other coastal stretches in the North Coast of Bahia, which also have NE-SW coastline orientation and are subjected to the same atmospheric conditions. In addition, the results allowed to identify the influence of beachrocks in long (Holocene), medium (about 50 years) and short term. In the long run the coastline of Arembepe, seen in plan, is stepped, which resulted from the successive formation of asymmetrical tombolos, which were gradually calcified. In the medium term, in the southwestern part of the studied area, where the beachrocks have only the role of closing a circulation cell (profiles 1 and 3), a progradation was observed in the last 46 years, possibly associated with changes in wave regime. On the other hand, the central part of the study area, where beachrocks are present both on the beach face and in the nearshore (profiles 4 and 5), is in equilibrium, showing that in 1976 the tombolos were already consolidated. In the northeast section, in turn, there is a situation of progradation and stability. This pattern can be attributed to discontinuous nearshore beachrocks, which produces a coastline with intercalations of salients and coves, with different behaviors. In the short term, it was observed a great sedimentary dynamics and variability of the position of the coastline in the southwest section, where the beachrocks present at the ends of the circulation cell allow a beach rotation throughout the year. In the central part, the presence of beachrocks on the beach face was responsible for a little seasonal variation in the beach profiles and little variability in the position of the shoreline, reinforcing the idea that the sandstones on the beach face hinder the sediment exchange on the beach. In the northeastern section, the variability of coastline position was intermediate to the other two sections. Finally, it is concluded that the protection provided by beachrocks was not homogeneous on the beach of Arembepe, depending on the different situations in which they are: closing circulation cells, attached to the beach face or presenting themselves discontinuously on the nearshore.

Autor(es): Oliveira, Sara Raquel Leal Barbosa Primeiro Orientador: Pertile, Noeli Abstract: Este trabajo propone presentar la dinámica espacial del mercado libre en el municipio de Feira de Santana, en el estado de Bahía y para la comprensión de esta dinámica se consideró la historia del libre mercado, la cual está totalmente relacionada con el origen y desarrollo de su municipio que a mediados del siglo XVIII inicia su proceso de asentamiento a partir de un mercado libre. En la actualidad, los mercadillos de la ciudad han sufrido cambios, siguiendo el rápido crecimiento urbano. La obra utiliza como recorte el mercado libre de la Estação Nova, en Feira de Santana, y tiene como objetivo general presentar sus dinámicas espaciales. Para fundamentación teórica se utilizó el concepto de paisaje, el cual tiene un carácter integrador de los elementos que componen el espacio geográfico, permitiendo la comprensión de las dinámicas en este espacio. Para lograr los objetivos propuestos, se recolectaron datos en documentos y literatura impresa y digital, y se realizaron visitas de campo donde se aplicaron cuestionarios y se realizaron entrevistas, que dieron como resultado datos que, luego del análisis, dieron como resultado la producción de gráficos, tablas, mapas y textos.

Autor(es): Silva, David Dias da Primeiro Orientador: Santos, José Antônio Lobo dos Abstract: This dissertation investigates the formation of peripheral areas as a phenomenon present in inland cities, based on the city of Serrinha, Bahia, between 2008 and 2024. The overall objective was to analyze the process of producing peripheral urban space in the city of Serrinha. The research was guided by the following guiding questions: How did the process of producing peripheral space in Serrinha unfold? Who were the main agents producing this space? What are the main characteristics that define this periphery? To carry out this analysis, the study defined the spatial framework concentrated in five neighborhoods: Conjunto H. Alvorada, Alto do Recreio, Treze, Santa, and Cidade Nova. The selection of these areas allowed us to examine socio-spatial inequality in its concrete form, revealing the different forms of occupation, appropriation, and spatial practices present in these locations. This study adopted a critical theoretical framework, grounded in the dialectical method. The procedures were based on qualitative research, using instruments such as bibliographic studies, field research with observations, interviews, photographic records, and the production of tables, graphs, and maps. The investigation demonstrated that Serrinha, inserted in the global economy, is subject to the capitalist logic of city production. In this mode of production, urban land is treated as a commodity, which generates and intensifies new forms of spatial segregation and imposes a new rhythm on local urban dynamics. The research concludes that, under this order, socio-spatial inequality prevails, characterizing and legitimizing the production of peripheral space in the city.

Autor(es): Santana, Anderson Castro de Primeiro Orientador: Dias, Clímaco César Siqueira Abstract: This work sought to produce a geographical, historical, theoretical-conceptual, and methodological review of regional studies and relevant regionalizations developed and implemented in the State of Bahia in the 20th century. The contributions generated within state planning institutions and academic institutions focused on geographical studies, whether universities or scientific associations, were analyzed. Thus, the work was developed following the principles of Livingstone's Geography of Sciences (2003), Vincent Berdoulay's contextual approach (2017), Milton Santos's events (2002), and Sheila Jasanoff's co-production (2004). The focus is on a geography and history of science that considers the internal and external aspects of scientific knowledge production, observing the circulation, rearrangements, and influences of ideas in the dialectic of the encounter between global and local science.
