Abstract: The coastal zone is a highly dynamic area, acting as an interface between the continent and the ocean, marked by natural and geoecological phenomena. Its vulnerability to coastal interactions and human interventions intensifies imbalances in the natural sediment balance, generating pressures and impacts on the environment, economy, and society, with direct effects on the landscape. The valorization of coastal areas, especially since the 1970s, driven by tourism and real estate expansion, led to disordered occupation in the coastal region of Aquiraz-CE. This occupation, characterized by the construction of rigid structures, compromised sensitive ecosystems such as beaches, fluvial-marine plains, and dunes. These impacts, combined with global climate change, have exacerbated the issue of coastal erosion, altering sediment dynamics and intensifying environmental degradation. In light of this scenario, the main objective of the research was to analyze the space-time variability of coastal-marine processes along the coastline of Aquiraz-CE over a period of 9 years (2015-2024), using online geoprocessing techniques. For this purpose, the Coastal Analysis via Satellite Imagery Engine (CASSIE) tool was employed, a free web application that allows access to the Sentinel-2A satellite image catalog through the Google Earth Engine (GEE) platform. This tool enabled the calculation of the space-time variation of the coastline. The data obtained were analyzed using the Linear Regression Rate (LRR) statistical method, which stands out for allowing the full use of the historical series of coastline data, offering a comprehensive analysis of changes over time and enabling the assessment of the studied beach’s condition regarding erosion, accretion, or stability over the analyzed period. The results of the coastline variation analysis in Aquiraz-CE indicated that a total of 36% of the studied area was classified as affected by erosive processes, especially in sections 1 and 2, which were recorded in urban clusters. Therefore, these results should be used as a reference for future coastal management planning, as the data provide an overview of the current state of erosion in the studied areas.

Abstract: This paper seeks to understand the spatial transformations and socio-environmental vulnerabilities that have occurred in the village of Preá, in Cruz-CE, due to the expansion of tourism, especially the influence of Jericoacoara. Throughout the research, it is notable how tourism, initially seen as a vector of development, has profoundly altered the local dynamic, changing the traditional way of life based on fishing and subsistence agriculture. With the increased circulation of tourists, the village's urbanization intensified, new ventures emerged, and the real estate market underwent strong appreciation, generating speculation and pressure on the territory. The effects caused by the construction of the Jericoacoara Airport and the implementation of public policies such as PRODETUR-NE were also analyzed. The data shows a significant population leap and the emergence of various commercial activities aimed at tourism, such as inns, restaurants, and shops. However, this disordered expansion brought challenges, such as compromising the natural landscape, the absence of adequate sanitary infrastructure, and an increase in waste production. From this, clear signs of environmental and socio-environmental vulnerabilities were identified, including risks of soil and aquifer contamination, coastal erosion, and the displacement of native residents. In the final section, I contribute by proposing that tourism in the region can be rethought under a sustainable logic, prioritizing the appreciation of local culture and ecological balance.

Abstract: In 2008, the international economic climate led the Brazilian government to adopt a series of countercyclical measures to mitigate the impact of the financial crisis on the country. Chief among these measures was the launch of the Minha Casa Minha Vida program in 2009. The program aimed to expand access to financed housing and, at the same time, boost the Brazilian economy by generating jobs and income in the construction sector. However, the government prioritized the growth of the construction and real estate sectors over addressing the housing shortage. Real estate agents were delegated the responsibility to determining the location of housing complex, which had negative consequences for residents and the state. This article analyzes access to essential services for residents of Residencial Orgulho do Ceará II, in the municipality of Pacatuba, Ceará. The analysis was based on the Urban Insertion Assessment Tool. Data were obtained through consultation with transportation companies, documentary research, field observations, interviews with residents, and the use of Google Earth and Maps. Seven years after the first housing units were delivered, residents continue to face problems related to the location of the development and the lack of public facilities.

Abstract: This study aimed to analyze and disseminate the morphological and structural characteristics, as well as to propose the evolutionary model of a circular structure located in Morro do Chapéu, Bahia, Brazil. The research included pre-field, field, and post-field stages, involving literature review, acquisition of drone images, generation of an orthophoto and digital elevation model (DEM), data analysis, and vectorization of structural lineaments. The main circular structure presents concentric terraces, dendritic radial drainage, and compartmentalization into five geomorphological units, including vegetated areas, isolated blocks, and exposed rock surfaces. Results indicate that its formation derives from the interaction between structural, weathering, and erosive factors, which transformed an originally more angular structure into a circular-shaped landform. It is concluded that the structure does not have a magmatic, volcanic, or meteorite impact origin, with its formation being possibly linked to the combined action of processes associated with sedimentary environments, such as weathering, erosion and structural control. Finally, further studies are recommended to investigate the tectonic and climatic influences on the relief evolution in the area, deepening the understanding of the processes and their impact on local and regional geomorphology.
