Jânio Guedes — 2025-08-10

Fatores socioeconômicos como, adensamento populacional, desmatamento, industrialização dentre outros, têm sido responsáveis, pela crescente degradação do meio ambiente. Tendo em vista a definição de que um Sistema Ambiental corresponde a um conjunto de elementos e das relações entre si e entre os seus atributos, neste contexto se torna importante ressaltar a necessidade do desenvolvimento de ações que conservem a natureza e que tenham como foco buscar estratégias capazes de levantar, ponderar e integrar dados dos componentes dos ecossistemas. Desse modo, esse trabalho tem como objetivo, realizar uma caracterização das unidades de paisagem da Bacia Hidrográfica do Rio Seridó. A pesquisa apresenta-se como descritiva quanto ao seu objetivo, demandando emprego de levantamento bibliográfico e cartográfico associado à pesquisa de campo, para mapeamento das unidades de paisagem. O levantamento bibliográfico subsidiou a discussão conceitual, enquanto a base cartográfica possibilitou o conhecimento integrado dos elementos ambientais, referentes ao relevo, clima, solos e vegetação. Como resultados destaca-se, em termos gerais, um clima semiárido, solos rasos e pedregosos desenvolvidos através da predominância de um intemperismo físico, uma vegetação de Caatinga hiperxerófila e a presença de rios intermitentes e/ou efêmeros, por vezes, perenizados através da construção de médios e grandes reservatórios hídricos. Com isso, apresentamos aqui uma revisão geral sobre a as unidades da paisagem da Bacia Hidrográfica do Rio Seridó. Onde a identificação dos padrões de organização da mesma assume grande importância nas ciências ambientais, pois, estes se constituem como ferramentas que oferecem subsídios no que se refere à resolução dos problemas socioambientais.

School tactile cartography

Armando Brito da Frota Filho — 2025-08-10

Inclusion has been a recurring and necessary topic in society, and the development and implementation of inclusive practices in education to make the learning process more effective are urgently needed. This study aimed to raise awareness among geography teachers in elementary education about the importance of inclusive practices involving tactile cartography. Workshops for the production and discussion of tactile maps were conducted to 23 teachers from the municipal public education system as part of the continuous training offered by the Municipal Department of Education - SEMED. The training aimed to empower teachers and prepare them for the new challenges and growing needs in education. The teaching of cartography is addressed in elementary and high school, and the workshop allowed teachers to create tactile maps so that students can experience the image through touch, which is especially important for students with visual impairments. The maps were elaborated using easily accessible and low-cost materials, and afterward, a roundtable discussion took place to evaluate the produced maps, with unanimous approval among the participants.

A DINÂMICA DOS PRINCIPAIS ESPAÇOS PÚBLICOS E DE LAZER DE UMUARAMA -PR, BRASIL

Jefersson Gabriel Alves Ferreira — 2025-08-05

Public spaces are essential for cities due to their leisure promotion, which improves people’s health and quality of live, as well as it contributes to the environment and to a sustainable economy. That said, in order to develop a research on public spaces, it is important to consider the area as a whole, not just the physical architecture, but also the practices and the social dynamics that it offers. Therefore, public space is the theme of this paper. It aims to analyze the interactions that happen in the main public recreation spaces at Umuarama, Paraná state, highlighting the usage, functionality, accessibility and sociability concerning the citizens. The theoretical approach consists on a qualitative and exploratory research, based on literature review, in loco research, as well as an analysis on official documents provided by Umuarama City Hall regarding the said places. The selected spaces were Aratimbó Lake, Uirapuru Grove, Indian Grove, and Miguel Rossafa Square. It was considered how people use these spaces, the accessibility and the existing infrastructure, and the role of public authorities when it comes to the social engagement among citizens. The results suggest the potentialities and strategies adopted by the city to make those spaces available for recreational purposes and physical activities, allowing them to be part of people’s coexistence, identity formation and quality of life.

EFEITO DA COBERTURA VEGETAL SOBRE AS PERDAS DE ÁGUA E SOLO EM PLINTOSSOLOS NA MICROBACIA DO CÓRREGO BURITIZAL, TOCANTINS

Leanne Teles Pereira — 2025-07-30

A ocorrência de erosão hídrica combinada com a gravidade dos impactos antrópicos são o foco dos esforços de conservação do solo, no qual práticas de manejo constituem importantes estratégias para redução dos impactos causados pela erosão. Diante disso, objetivou-se avaliar a influência da cobertura vegetal na perda de solo e água da microbacia hidrográfica do Córrego Buritizal, Estado do Tocantins. Para realização do experimento foram definidos três locais para implantação das áreas de coleta de dados para estimativa de perda de solo. Essa determinação ocorreu de modo em que houvesse dois tipos diferentes de interação solo-vegetação. Ao todo ocorreram 50 coletas do período de 26/01/2016 a 30/04/2018, as quais eram intensificadas no período chuvoso da região. Foram feitas análises de textura e teor de matéria orgânica. Os dados referentes à perda de solo e perda de água em enxurrada foram submetidos ao teste Shapiro-Wilk e Análise de Variância (ANOVA). As análises estatísticas foram executadas utilizando software R 4.1.3. Os resultados obtidos reforçam que a pluviometria possui grande influência sobre os índices de perdas de solo e de água, sendo a cobertura vegetal determinante para a redução das perdas de água e solo em área de Plintossolo no Estado do Tocantins.

INFLUÊNCIA DA COBETURA VEGETAL NAS PERDAS DE SOLO E ÁGUA EM CERRADO TOCANTINENSE

Thaiana Brunes Feitosa — 2025-08-10

The occurrence of water erosion combined with anthropic impacts are the main causes of soil degradation, in which management practices are important for soil conservation. In view of this, the objective was to evaluate the influence of vegetation cover on soil and water loss, in Oxisol plots, in experimental areas located in the hydrographic microbasin of Córrego Buritizal, state of Tocantins. To carry out the experiment, three locations were defined for the implementation of data collection areas to estimate soil loss. This determination occurred so that there were two different types of soil-vegetation interaction. In all, there were 50 collections from January 2016 to April 2018, which were intensified in the rainy season in the region. Data referring to soil loss and water loss in run-off, were checked for normality using the Shapiro-Wilk test, and were analyzed following the analysis of variance procedure. Statistical analyzes were performed using R 4.1.3 software. The results of this experiment confirm the fact that precipitation is the main agent of water and soil loss in the experimental plots, mainly in exposed soils. Since the presence of vegetation cover is crucial for the reduction of water and soil losses and reduces the correlations between these losses and the precipitation rates during the years of observation.

ASPECTOS DA EXTENSÃO E QUALIDADE DE ÁGUAS SUPERFICIAIS E SUBTERRÂNEAS PARA USOS MÚLTIPLOS NA BACIA HIDROGRÁFICA DO RIO GUAJIRU (RN)

Michele Barbosa da Rocha — 2025-08-05

A água é uma riqueza natural considerada fonte de vida, e seu acesso universal é um direito humano consagrado nas metas globais da agenda 2030 para o desenvolvimento sustentável. A relevância do tema motivou investigar a disponibilidade e a qualidade das águas subterrâneas e superficiais para usos múltiplos na Bacia Hidrográfica do Rio Guajiru (BHRG), mediante levantamento de poços cadastrados nas bases de dados da CPRM, da SEMARH e da Agência Nacional da Águas (ANA) e de amostras de águas coletadas para análises químicas. Com o programa QGIS 3.16.11 foi possível analisar as variáveis situação dos poços, tipologia, natureza, tipo de uso, profundidade, vazão e qualidade e elaborar mapas com informações dos poços, cacimbas, açudes e pontos de coleta de amostras de águas. Os resultados demonstram que o poço PC01 apresenta água imprópria para consumo humano, com valores de pH em desacordo com a legislação vigente. As análises das águas superficiais revelaram que apenas a amostra MB008, coletada na Lagoa de Extremoz, apresenta resultados dentro dos valores de referência estabelecidos pela Resolução CONAMA nº 357, de 17 de março de 2005. O estudo evidencia a urgência do estabelecimento de ações de monitoramento da qualidade das águas e de conscientização da população sobre a preservação dos recursos hídricos e sobre os riscos para a saúde humana de consumir água sem nenhum tipo de tratamento.

Free remote sensing data as a resource for generating a model of susceptibility to erosion risk

Julia Cucco Dalri — 2025-07-30

The installation of Transmission Lines (TL) provokes disturbances in the environment, which reacts in different ways. The suppression of vegetation, even when limited to what is necessary for execution of the project, may cause erosive processes. Spatialized materials have made the monitoring of large portions of land viable. Data from the GPM (Global Precipitation Measurement) constellation allows access to rainfall data even in areas which do not have pluviometric stations. Also by satellite, the landscape can be represented with SRTM (Shuttle Radar Topography Mission) images. Similarly, maps of soil erodibility and the necessary land use for the risk of erosion diagnostics methodology can be obtained. Therefore, a logic is methodologically developed in which freely obtained input data follow a conceptual model, which defines the variables and their relationships in the potential issue’s context, while having replication accessibility in mind. Of the 43 gaps present in the pilot tracing located in Minas Gerais, Brazil, four of them received the “likely” risk of erosion classification in a period without record of any meaningful rainfall. The methodology mirrors an evaluation which increases the risk as long as the rains occur e and that can be adapted to other biomes by modifying parameters based on their characteristics.

Variability of precipitation extremes in Manaus

Maria Betânia Oliveira — 2025-08-03

The precipitation regime in Manaus is characterized by a marked temporal variability due to the performance of meteorological systems of different scales. Additionally, local characteristics, whether proximity to the river or surface coverage, induce the formation of isolated convective clouds or in association with pre-existing systems, resulting in intense accumulations of precipitation unevenly distributed in the city. In this sense, the objective of this study was to evaluate the occurrence of extremes precipitation events (PE) recorded in Manaus from March 2010 to May 2020, using data from a network of stations implemented during the execution of the Project Rede de Mudanças Climáticas da Amazônia (UEA-HOBO Network of the REMCLAM project). The quantile technique was applied to identify precipitation extremes and box plots were used to assess the distribution of events in different areas of the city and season of the year. The results indicated a marked seasonal variability with a higher frequency of PE associated with periods of greater precipitation intensity, although these also occur in less rainy periods of the year, but with less intensity. The occurrence of PE was observed in all areas of the city analyzed in this study, with a predominance of the most intense events in the central-southern area of the city. Larger numbers of events were associated with positive precipitation anomalies, especially in the wettest months, but without a direct relationship with the occurrence of El Niño - Southern Oscillation events.

GEOTECNOLOGIAS APLICADAS AO ENSINO DE GEOGRAFIA

Jhennifer Tais Vieira Habowski — 2025-08-05

Os mapas são importantes para o ensino de Geografia e para a compreensão do espaço. A problemática deste trabalho é como a Cartografia Colaborativa e/ou geotecnologias podem contribuir para o ensino de Geografia, abordando o processo metodológico de construção de um mapa e a possibilidade de compreensão crítica de seu processo representativo. O objetivo do trabalho é investigar as potencialidades das geotecnologias e da Cartografia Colaborativa para o ensino de Geografia, identificando os conhecimentos prévios e propondo oficinas com o uso de ferramentas geotecnológicas aplicadas ao ensino. O trabalho em questão foi na Escola Municipal de Ensino Fundamental Professora Cândida Zasso, no município de Nova Palma, no Rio Grande do Sul, com turmas do 6º e 7º ano. Foram planejadas quatro oficinas com diferentes temáticas, ao longo de três dias. Com resultados, temos a discussão acerca da compreensão desses mapas e de como os alunos estão inseridos em tal contexto, refletindo na importância da formação de um cidadão crítico. Logo, acredita-se que essas ferramentas geotecnológicas apresentadas foram de extrema importância para o ensino de Geografia, fazendo com que os alunos compreendessem os elementos do mapa. Ressalta-se, no entanto, que eles não necessariamente atingiram o letramento cartográfico, pois isso demanda um processo ao longo da formação do aluno. Mas, através do uso dessas ferramentas, pode-se ter uma maior interpretação de um mapa e a relevância da criticidade na formação de um cidadão. Além do uso do mapeamento colaborativo como elemento para a descrição de sua visão sobre o meio e de como estão inseridos, estabelecendo a relação sociedade e natureza, fazendo assim os alunos não apenas reprodutores de informações, mas protagonistas de suas histórias no mapa. Portanto, a pesquisa contribuiu para fomentar a alfabetização e o letramento cartográfico, abrindo possibilidades para novos olhares sobre Nova Palma, por parte dos participantes dela.

Human thermal comfort in the perception of city dwellers:

João Rodrigues de Araújo Júnior — 2025-07-30

The city of Sobral, located in the semi-arid Northeast, is characterized by high temperatures and low humidity for much of the year, in addition to being known for the rapid expansion of its urban mesh in recent decades. The constant changes in its urban space, privileging the sealing of the soil to the detriment of the green areas, ended up increasing the increase in local temperature, contributing to a greater thermal discomfort of the city dwellers. However, in a more recent period, Sobral has gained prominence in the execution of public works/policies, on multiple fronts, with the requalification of public leisure spaces, especially the Squares and Urban Parks, promoting areas with greater afforestation and recovery of water bodies, even if the city still has public open spaces that have not been properly restructured/requalified. The proposed research aims to identify and evaluate the perception of city dwellers about Human Thermal Comfort in these open public spaces, confronting this perception with microclimatic analyses carried out in five parks/public squares, based on interviews and seasonal climate measurements. The results show that those public spaces located in more densely urbanized areas and with a high flow of people and vehicles presented a higher thermal load, which was also pointed out by the passers-by of these squares/parks. On the other hand, the Urban Parks and the square closest to the Meruoca Residual Massif presented, especially in the rainy season and pre-rainy season, milder records, consistent with the comments made by city dwellers interviewed that indicate these areas as more comfortable for the practice of sports and leisure activities.

Territorialization and deterritorialization of rural schools in the northern mesoregion of Amapá state

Cássia Betânia Lopes dos Santos — 2025-08-03

Rural education is an important public policy for social transformation that strengthens the identity and territory of individuals living in rural areas. Schools in rural areas are one of the main spaces where this public policy is materialized, but in the northern mesoregion of the state of Amapá, the lack of public policies aimed at the real needs of rural, water, and forest populations has seriously affected education. Our research combined data from the Inep school census, records from the Pastoral Land Commission on conflicts in rural areas, and secondary sources such as theses, dissertations, articles, and electronic newspapers. The results indicate that the rural areas in the northern mesoregion of Amapá are undergoing profound changes and that the functioning dynamics of rural schools have been deeply affected. The main factors are activities related to mining and agriculture, as well as the lack of participation of the local population in decisions about the creation of large preservation areas. Therefore, it is crucial to implement public policies that promote access to basic rights, especially rural education, and that seek social participation and environmental preservation more effectively.

CARACTERIZAÇÃO DE PARÂMETROS FÍSICO-HÍDRICOS DO SOLO E A INFLUÊNCIA NA VERTENTE NO BAIRRO CAMOBI EM SANTA MARIA, RS

MARINÉLI MORAES GABERTI — 2025-07-30

In the shaping of the slopes' profile, several processes are involved, both in the supply and removal of material, resulting from the predominant morphogenesis mechanism. The importance of the relief factor in soil formation is highlighted, emphasizing the control exerted by the dynamics of water flows in the subsurface along the slope profile. The aim of the work was to characterize the evolutionary dynamics of a slope from the physical and hydric properties of the pedogenetic horizons described in a soil profile in a slope segment established on sedimentary lithology of the Santa Maria Formation - Alemoa Member, located in Santa Maria, RS. The methodological approach was followed where the slopes evolve from the influence of the physical-hydric properties of the pedogenetic horizons. The physical-water parameters such as particle size distribution, particle density (γs), bulk density (γd), micro and macroporosity, total porosity (n), saturated hydraulic conductivity (Ksat), consistency limits were determined: Contraction limit (LC), plasticity limit (LP), liquidity limit (LL) in addition to plasticity index (PI), Unified Soil Classification System (SUCS) denomination and textural class denomination for each of the pedogenetic horizons in the soil profile. It was observed that the lateral exfiltration process intercepting the land surface marks the transition to a more concave segment alternating from the upper third of the slope reinforcing the idea where the intensification of the exfiltration in the concave segment of the slope occurs in face of the influence of the physical-hydric parameters of the pedological cover.

COBERTURA VEGETAL E USO DA TERRA

Túlio Viana Bandeira — 2025-08-03

The geographic studies are essential for comprehension spatial dynamics and processes, given that the changes in the environmental framework are directly related to cultural, political and economic aspects, thus permeating the various aspects in which Geography is inserted. In this sense, this article aims to comprehend the forms of vegetation cover and land use, based on the identification of the space-producing agents and their dynamics of modifying the landscape of the municipality of Guaiúba-CE. For this, the methodological path taken is given by the theoretical union of analyzed concepts and processes, in association with the methodology of Monteiro's standard years (1976). In addition, research procedures and techniques were used, such as - fieldwork, use of geotechnologies and cartographic production, in order to compose the proposed discussions. As a result of the research, it was possible to demonstrate the amplitude of the municipality's environmental framework and, mainly, to treat the diversity of the actions of the space-producing agents, which validates the dimension of the discussion in the geographical scope.

Geomorphological mapping of Section Four river basin, direct afluent of the upper course of the Uruguay river, Volta Grande - SC

Matheus Vinícius dos Santos — 2025-08-08

The present study aimed to map the Patterned and Forms that compound the Seção Quatro river basin, located in the upper course of the Uruguay River. The interpretation of aerial photos from the years 1957 and 1978 was realized through stereoscopy, and using cross-sectional profiles, slope maps, contour lines and shaded images. This features were confirmed in field work. The Accumulation Patterned is composed by the Plateau Forms (staggered in five hypsometric levels), slopes and confined valleys. It presents shallow surface formations, with local occurrences of inverted horizons and steeper slope values in the hydrographic basin, being classified as gently undulating to strongly undulating. The Accumulation Patterned includes alluvial fan forms, open and plan fluvial valleys, agradational valley, colluvium ramp and the floodplain of the Uruguay River, with thicker surface formations, with plan to gently undulating relief. The contrast between the Patterned that compose them is clear, the surface formations indicate the absence of in situ materials, marked by the occurrence of colluviums that are remobilized to the lower slope and valley, and with a sedimentological characteristic without pedogenetic connotation. Such facts record the predominance of morphogenesis and erosion processes in the formation of the current local geomorphological landscape.

POLITICAL AND REGINONAL GEOGRAPHY IN AN EVER-CHANGING WORLD: AN INTERVIEW WITH DR. ANSSI PAASI

Gloria Vargas — 2025-07-29

In this interview, we explore some of Professor Anssi Paasi´s thoughts and reflections on cornerstone aspects of political and regional geography. We discuss his comprehension of borders, the interactions between space, power, and society, and his original and useful understanding of regional formation and institutionalization. His insights and profound understanding of political and regional phenomena in geography allow him to revise his assumptions in light of an ever-changing world that redefines its frontiers, creates political and regional spaces, and constantly demands new and efficient interpretations.
