In this context, this thesis proposes a geodynamic model of Functional and Propositional Zoning, grounded in Landscape Geoecology, to support sustainable management of the CRB and contribute to the achievement of the Sustainable Development Goals (SDGs 6, 11, 13, and 15). The methodological approach is systemic and integrative, combining analyses of physical components (relief, geology, soils, climate, vegetation, and hydrography), land-use and land-cover patterns, environmental, social, and socio-environmental vulnerability indicators, as well as geoprocessing techniques and spatial statistics. Landscape compartmentalization into geoecological units enabled interpretation of geosystem structure and functioning across the upper, middle, and lower reaches of the basin. Results reveal pronounced spatial heterogeneity within the CRB, with environmentally stable areas associated with high naturalness and moderately stable to unstable sectors concentrating the most significant socio-environmental conflicts. The integration of environmental fragility and social vulnerability highlights critical zones particularly in transition areas and the lower basin where anthropogenic pressures intensify environmental and social risks. Based on this diagnosis, a functional zoning scheme was proposed, comprising conservation zones, sustainable use zones, geoenvironmental requalification zones, and priority territorial ordering zones. The study concludes that Landscape Geoecology provides an effective framework for environmental planning in tropical river basins, offering robust support for public policy, vulnerability reduction, and integrated natural resource management. Recommendations include strengthening environmental monitoring, incorporating higher-resolution spatial and temporal data, and implementing participatory zoning with local authorities and communities Tipo: Tese Thu, 01 Jan 2026 00:00:00 GMT http://repositorio.ufc.br/handle/riufc/85395 2026-01-01T00:00:00Z http://repositorio.ufc.br/handle/riufc/84907 Título: Cultura e representações da paisagem cajueira no Nordeste do Brasil: dimensões geoeducacionais de uma tropicalidade frutífera Autor(es): Silva, Silvia Heleny Gomes da Abstract: Understanding geographic space requires more than sight; it requires smelling, touching, listening, tasting, imagining, and feeling. The expressions of cashew in everyday life reveal a true polyphony of landscape, and the relationship with this fruit dates back to ancient times. This research was based on the hypothesis that knowledge of cashew landscapes fosters a rich geographical understanding, manifested through literature, cuisine, music, and visual arts. As a general objective, we sought to understand its multiple representations through an analysis of the spatial dynamics of the cashew landscape in the states of Ceará, Piauí, and Rio Grande do Norte. This research was motivated by the lack of systematization and organization of knowledge surrounding the history of cashew, which is scattered across many media and lacks updated interpretations of what cashew represents today in its different cultural manifestations. To this end, we designed specific objectives to achieve this goal. Our specific objectives were: 1) To investigate how food culture constitutes cultural heritage; 2) To research the spatial dynamics of cashew in the local, regional, national, and global context; 3) To analyze the geographies of cashew; and 4) To discuss the role of geoeducation through Food Heritage Education. This research is qualitative and quantitative and exploratory in nature, involving bibliographical readings, surveys of cashew landscapes, planning and conducting fieldwork, and the development of a geoeducational product. The method used was semiotic, based on the concepts of Charles Sanders Peirce. We consider cashew as a fruit that symbolizes polysemic tropicality, reinforcing the nutritional potential strongly identified in the Northeastern and Brazilian landscapes; in addition, it reaches a global scale through complex cultural phenomena. These phenomena demonstrate the central perspective of this thesis: the networked articulation of a tropical cashew landscape, accessible to geographic education, aggregates values and promotes social identities capable of shaping a Cashew Cultural Region (CCR). It is through the integration of multiple cajualities (cashew events and festivities) that the CCR is formed, blending tradition and innovation. Proposing this concept to reflect on public policy related to cashew food heritage is the objective of this research.

These changes, supported by the phenomenon of agricultural modernization, can be observed in the processing and production of cassava since the 1980s, but were accentuated mainly in the 1990s, along with the introduction of mechanization, which resulted in new dynamics and greater territorial reach of the productive spatial circuits. The cooperation between the different institutions and organizations involved was also growing, although it occurred in a quite uneven way across Brazil. Therefore, the general objective of this work was to analyze the contradictions involved in the modernization process of the brazilian cassava agribusiness based on productive spatial circuits and circles of cooperation in space. The specific objectives of this work were: to understand how the evolution and dynamics of the cassava agribusiness occur in Brazil; to explain the relationship between the agro- industrialization of cassava and family-based peasant production; to examine the spatial production circuits, as well as the organization of their cooperation circles within the Brazilian cassava agribusiness; and to discuss the importance of the studies on the Geography of Food in relation to the productive circularity of cassava. The breadth of the spatial scope, the brazilian territory, and the challenge circumscribed by such a significant delimitation, culminated in a multi-scalar analysis, which highlighted processes of subordination and territorial cooperation regarding the cassava agribusiness and its spatial production circuits. The bibliographic and documentar research, the collection and tabulation of secondary data, and the creation of maps and cartograms were essential in connection with the methodological procedures necessary to achieve the aforementioned objectives, as well as to carry out the research work in a more comprehensive manner. The geographical dimension is highlighted when addressing a relevant topic capable of explaining the use of the territory through the dynamics of flows, by emphasizing the unity between the different productive stages. As a result, it was found that within the brazilian cassava agribusiness, the spatial production circuits and the circles of cooperation in space articulate different scales of analysis and reveal the complexity of the dynamics involved in the organization of production, labor relations, and the different levels of technical incorporation. In the social sphere, the work contributed to a reflection on the need to strengthen public policies aimed at family farming and the value of foods such as cassava, which continues to play a strategic role in food security, in contrast to a process that enables the expansion of agribusinesses based on monocultures, land concentration, and the prioritization of commodities aimed at the international market Tipo: Tese Wed, 01 Jan 2025 00:00:00 GMT http://repositorio.ufc.br/handle/riufc/84166 2025-01-01T00:00:00Z http://repositorio.ufc.br/handle/riufc/84125 Título: Geoecologia das paisagens aplicada ao planejamento ambiental regional e local do parque nacional dos lençóis maranhenses, Maranhão, Brasil Autor(es): Borges, Jordane de Oliveira Abstract: The Lençóis Maranhenses National Park (LMNP) is one of the largest natural reserves and a World Natural Heritage Site, under the jurisdiction of the Ministry of the Environment, protected and managed by ICMBio. Due to this status, studies within the field of Landscape Geoecology have become increasingly essential, as LMNP represents a conservation unit with unique characteristics, structure, and dynamics. In light of this, the objective of this study is to analyze the landscape dynamics of the Lençóis Maranhenses National Park from an interdisciplinary perspective, based on the Geoecology of Landscape approach, aiming to support environmental planning. A quantitative-qualitative methodology was adopted, grounded in the scientific and methodological framework of Geoecology of Landscape. The Lençóis Maranhenses National Park and the surrounding municipalities were treated as a single territorial unit, following the methodological phases of organization, inventory, analysis, diagnosis, and proposal. The interaction among the landscape elements and their interrelated processes allowed the identification and delimitation of Geoecological Units and their natural-anthropogenic processes, as well as their structural and functional analysis. These units comprise: Coastal Plain, Fluvio-Marine Plain, Fluvial Plain and Terrace, Coastal Plateau, and Subcoastal Plateau. The geoenvironmental dynamics of LMNP are highly variable, primarily influenced by wind action, hydrological dynamics, rainfall, and land use. Despite these factors, the forms and functions of the Geoecological Units and Subunits within the study area showed limited variation, mainly due to their genesis and the active dynamics occurring at the ocean-continent interface. Regarding the geoecological condition, none of the Geoecological Units evaluated in this study exhibited partial or generalized loss of spatial and functional structure, nor a gradual elimination of ecological functions, and the geosystem remains capable of performing its geoecological roles. Based on the results concerning the environmental state (geoecological condition), seven functional zones were identified: Conservation and sustainable tourism zones; Natural stabilization zones; Environmental protection and plant extractivism zones; Animal extractivism and artisanal fishing zones; Urban expansion zone of Barreirinhas; Agriculture and urban expansion zone; Agro-pastoral land use zone. The geoecological functional zoning of the Park and its surroundings provided insights for more balanced actions aimed at both conservation and human use, guiding environmental planning by considering the area’s environmental characteristics, vulnerabilities, and potentialities Tipo: Tese Wed, 01 Jan 2025 00:00:00 GMT http://repositorio.ufc.br/handle/riufc/84125 2025-01-01T00:00:00Z
