Abstract Geomorphological studies are crucial for understanding the evolution of relief, and when associated with cartography, they enhance the interpretation and knowledge of environmental dynamics. Hence, historical cartography is essential for the documental rescue of landscapes, which, based on the mapped geoforms, enhances post-discovery studies for the state of Ceará, Brazil. Historically, this state was intermittently mapped in the sixteenth and seventeenth centuries but gained greater attention from Portugal in the eighteenth and nineteenth centuries after its separation from Pernambuco. Despite this, cartographic studies on coastal geoforms are not typical for the Ceará coast over a given period, highlighting the importance of this investigation. Therefore, this article aimed to study the environmental history of the coastal geoforms mapped on the extreme west coast of Ceará in the seventeenth and eighteenth centuries. This research had a qualitative and exploratory basis, with cartographic documental surveys online and in loco, covering the municipalities of Jijoca de Jericoacoara, Camocim, and Barroquinha. Fifty maps of different origins were collected, three of which were used: a French sketch and two Portuguese maps. In the French material of 1615, geoforms in the Cape de la Tortue indicated the presence of a rocky island separated from the mainland. From the Portuguese map of 1629, a well-cut coastline was noted, identifying Buraco das Tartarugas, where there were two islands of different sizes. In the 1794 map, an island in the cove called Geri qua Coá was noted, differing in landscape from the previous ones, as it did not have tombolos connected to the continent. The cartographies presented particularities for revealing a possible advance in the local sea level. Thus, it is possible to motivate future research in the area of historical cartography as a tool for the analysis of the paleogeographic evolution of the coastal zones of Ceará.

Resumo Em 2019 um derramamento de petróleo de origem desconhecida afetou várias localidades do litoral brasileiro. Nessa pesquisa, objetivou-se apreender as percepções das marisqueiras do estuário do Rio Jaguaribe, Ceará, acerca da exposição ao petróleo e suas consequências. Utilizou-se o grupo focal como técnica para a coleta de dados e o software Iramuteq para o processamento e análise do material. Os resultados apontaram para a criação de duas categorias analíticas: implicações sociais, econômicas, produtivas e de consumo de alimentos das famílias marisqueiras; e os saberes, a participação e a vigilância no contexto de (in)visibilização da exposição ao petróleo. Percebeu-se que as marisqueiras e suas famílias são uma população muito exposta aos impactos negativos causados pelo derramamento de petróleo por se apresentarem significativos sob as perspectivas socioeconômicas, ambientais, produtivas e de saúde. Chama-se a atenção para as políticas de saúde e assistência social para as trabalhadoras, consequências na segurança alimentar, hídrica e nutricional das famílias e sobre o reconhecimento de seus saberes e práticas, construídos dentro de um modo de vida tradicional que produz e reproduz a existência numa estreita relação sociedade/natureza.

Abstract In 2019, an oil spill of yet unknown origin affected several locations on the Brazilian coast. The purpose of this research was to capture the perceptions of women shellfish gatherers in the Jaguaribe River estuary, Ceará, about exposure to oil and its consequences. The focal group technique was used for data collection and the Iramuteq software for the processing and analysis of the material. The results indicated the creation of two analytical categories: Social, economic, food production and consumption implications of shellfish gatherer families; and the knowledges, the participation and the surveillance in the context of (in)visibility of exposure to oil. It was observed that shellfisherwomen and their families constitute a population that is very exposed to the negative impacts caused by the oil spill, as they are significant from the socioeconomic, environmental, food production, consumption and health perspectives. Attention is drawn to health and social assistance policies for these fisherwomen/shellfish gatherers, with consequences on the food, water and nutrition security of families and the recognition of their knowledges and practices, constructed within a traditional way of life that produces and reproduces the existence in a close society/nature relationship.
