Nevertheless, socioeconomic and spatial transformations are already observable in inland cities of the country that have received campuses. This dissertation addresses the transformations that the Universities and the IF have brought about in Crateús/CE and its surrounding region, with particular emphasis on the IFCE Campus and its relationship with the territory through teaching, research, and especially extension activities. The main objective of this study is to assess the contributions of these campuses—particularly the IFCE Campus and its extension activities—to the development of the region. To this end, we collected data from these institutions and conducted interviews with directors, extension professors, and scholarship holders, as well as with producers, entrepreneurs, and representatives of other public agencies and civil society organizations active in the city and region. The research supports the thesis that these policies have reached inland areas, but in an incomplete way, lacking the structural and human resources necessary to fully realize their potential. It demonstrates that teaching has effectively contributed to education in the region, especially through undergraduate teacher-training programs, but that such contributions are not reproduced to the same extent in research and extension. Among the main reasons, in the case of IFCE, are the small number of professors working in higher education courses—which makes it difficult or impossible to carry out activities beyond teaching—and the lack of financial resources for project development. The arrival of these institutions, in combination with other policies, has significant potential to contribute to the region’s development, but this potential has been diminished by the lack of adequate means.; RESUMEN. Las políticas públicas de expansión de las Universidades Federales y de creación y expansión de los Institutos Federales de Educación (IFs) datan de comienzos de los años 2000; por lo tanto, son recientes. Sin embargo, las transformaciones socioeconómicas y espaciales ya son observables en ciudades del interior del país que recibieron campus. Esta tesis trata sobre las transformaciones que las Universidades y el IF han promovido en Crateús/CE y en la región, con especial énfasis en el Campus del IFCE y su relación con el territorio a través de la enseñanza, la investigación y, especialmente, la extensión.El objetivo central del trabajo es dimensionar las contribuciones de estos campus, en particular las del Campus del IFCE y de su extensión, al desarrollo de la región. Para ello, realizamos levantamientos de datos de estas instituciones y entrevistas con directores(as), profesores extensionistas y becarios(as), además de productores, empresarios y representantes de otros organismos públicos y de la sociedad civil que actúan en la ciudad y la región. La investigación confirma la tesis de que estas políticas llegaron al interior, pero de manera incompleta, sin los medios estructurales ni de personal suficientes para alcanzar plenamente su potencial. Demuestra que la enseñanza ha contribuido eficazmente a la formación en la región, especialmente en las licenciaturas, pero que esta contribución no se reproduce en la misma proporción en la investigación y la extensión. Entre las principales causas, en el caso del IFCE, se encuentran la reducida cantidad de profesores que actúan en los cursos superiores, lo que dificulta o imposibilita la realización de otras actividades más allá de la enseñanza, así como la falta de recursos financieros para el desarrollo de proyectos. La llegada de estas instituciones, en asociación con otras políticas, tiene un gran potencial de contribución para el desarrollo de la región, pero este se ha visto limitado por la falta de los medios adecuados.

The main objective was to examine how eco-hydrological and biogeomorphological seasonal dynamics control the morphology of non-perennial rivers, particularly by understanding how seasonal hydrological variations influence vegetation distribution and resilience, as well as channel morphological evolution.The methodology integrated multiscale analyses: at the drainage network scale, using Sentinel-2 NDVI time series (2016–2023) and rainfall data; at the reach scale, through UAV-based monitoring for the production of orthomosaics, digital terrain models (DTMs), and calculation of the VIgreen index; and at the quadrat scale, using permanent plots to monitor ecological succession across different geomorphic units (channel bed, bars, and margins).The results demonstrated a strong positive correlation between NDVI and accumulated precipitation (60–90 days), highlighting the rapid response of vegetation to rainfall pulses. Monitoring with VIgreen revealed marked seasonal dynamics, with increased vegetation biomass during the rainy season and reduction during dry periods. Quadrat monitoring showed that geomorphic units such as pools and margins sustain higher vegetation diversity and stability, whereas bars and active channels exhibit greater species turnover. Morphological analysis identified the instability dynamics of unvegetated sediment bars, in contrast to the stability of vegetated bars, which were only significantly reshaped by extreme hydrological events.It is concluded that the interaction among hydrology, geomorphology, and vegetation constitutes a non-linear system, sensitive to specific hydrological thresholds, with seasonality acting as a key driver of morphodynamics and ecological organization in non-perennial channels. These findings highlight the importance of incorporating eco-hydrological and biogeomorphological approaches in the understanding and management of fluvial systems in semi-arid regions.

Thus, the present study aims to investigate water conditions through correlations between environmental constraints, land use and land cover, and water quality in the Agon stream microbasin. To this end, land use and land cover mapping of the area of interest was performed using data from the MapBiomas project, alongside water sampling (surface and groundwater) for the analysis of physical, chemical, and microbiological parameters. To understand the degree of aquifer vulnerability in the Agon stream microbasin, the GOD method (Groundwater occurrence, Overall lithology, and Depth to water table) was employed. The generated data allowed for an integrated analysis of the parameters established by the Ministry of Health (Ordinance 888/2021) and the CONAMA Resolutions (No. 357/2005 and No. 396/2008). The relevance of this study is justified by the microbasin’s location in the Brazilian Semi-arid region, a region characterized by a negative water balance, which reinforces the importance of conserving existing water resources. Additionally, there is a scarcity of research focused on understanding how water contamination in the local context can increase water scarcity in the region. Therefore, there is a need for detailed analyses regarding contamination and water scarcity, as water pollution represents a serious risk to public health and ecological balance. The juxtaposition of environmental characteristics — an unconfined alluvial aquifer embedded in crystalline geology, under a semi-arid climate with fluctuations in annual and interannual rainfall patterns, intermittent flow, and intense land use and cover — combined with high aquifer vulnerability (GOD index of 0.56), resulted in a critical situation in the Agon stream microbasin. The results revealed that the water is unfit for consumption at all sampling points due to microbiological contamination, high nitrate levels, and other physical-chemical alterations (turbidity and Total Dissolved Solids - TDS). This reality found in the Agon microbasin is dialectically contradictory: it is an area that, while facing socioeconomic and environmental difficulties related to water scarcity, is simultaneously submerged in a logic of significant contamination Editor: Universidade Federal da Paraíba Tipo: Dissertação Mon, 26 Jan 2026 00:00:00 GMT https://repositorio.ufpb.br/jspui/handle/123456789/38020 2026-01-26T00:00:00Z https://repositorio.ufpb.br/jspui/handle/123456789/38014 Título: Território e práticas agrícolas no município de Lagoa Seca/PB: espaço de disputas e de luta para a produção de alimentos saudáveis Autor(es): Silva, Rodrigo Brito da Orientador: Galvão, Josias de Castro Abstract: This dissertation addresses the initiatives of civil society and public organizations aimed at strengthening agroecological actions in the municipality of Lagoa Seca, Paraíba, Brazil. The objective of this research is to analyze the construction of territoriality by the National Articulation of Agroecology (ANA), in Lagoa Seca/PB, demonstrating its contribution in the production of new socio-spatial dynamics in the countryside, from the agroecological transition and in the confrontation of the practices disseminated by the green revolution. The qualitative research relies on primary sources, such as ANA documents and interviews with representatives of the entities. The starting point is the historical rescue of the research region, seeking to perceive the territorial organization of the territory at different scales, according to its specificities and characteristics. It is well known that the construction of an alternative production territory is a long and complex process. However, the process of articulation and agroecological transition presents itself as a social contribution, as it creates models of projects to be followed in other locations and at different scales, seeking the implementation of public policies that rekindle the hope of a healthier countryside. We conclude that ANA, by representing organizations, establishes the process of forming an agroecological field in the country, a notion of agroecology with the objective of materializing public policies in favor of society and which has positively affected its performance in productive changes in the field in Lagoa Seca/PB.
