Resumo Áreas ocupadas por populações de baixa renda frequentemente estão suscetíveis a deslizamentos e inundações tanto devido à injustiça socioespacial quanto à ocorrência de eventos extremos relacionados às mudanças climáticas. Este estudo analisa a possibilidade de trabalhar elementos de percepção de risco associados à Ciência Cidadã e à Aprendizagem Social a partir de mapeamento socioambiental com estudantes da rede pública do estado de São Paulo. A pesquisa incluiu palestra, trabalho de campo e uso de Sistema de Informação Geográfica (SIG). Evidenciou-se que, além de engajar os jovens em atividades pontuais de redução de riscos, é necessário promover estratégias que envolvam a população por meio de metodologias participativas e da divulgação científica para construir uma cultura preventiva e de resiliência.

Anthropic transformations, partly driven by human activity, have been causing disruptions in ecological patterns and processes within watersheds over the years, leading to landscape instability. Within this context, Hemeroby evaluates the intensity of alterations in landscape structure and function, classifying them based on their level of naturalness. Thus, the objective of this study is to analyze the landscape of the Turvo River Watershed in Barra do Turvo/SP according to Hemeroby levels. Vector files of vegetation cover and land uses from 1990, 2000, 2010, and 2020 were integrated using the ArcGIS Intersect tool with vector files of pedology, geology, geomorphology, relief amplitude, slope, climate, and erodibility. After combining the files, Hemeroby levels were classified to produce maps. The results of Hemeroby levels in the studied watershed ranged from Minimum (encompassing forest classes and water), with low technological and energy dependence for maintaining ecological functions, to Very High (covering the urban area of Barra do Turvo/SP), with high technological and energy dependence and low self-regulation capacity. The landscape of the investigated watershed exhibits a high level of human intervention due to agricultural practices, resulting in secondary vegetation and urban influence. Thus, the study of Hemeroby is important for evaluating negative impacts on the local ecosystem, thereby aiding in landscape planning and decision-making at municipal, state, and national levels.

A expansão da agropecuária juntamente com o processo de urbanização são fatores que podem contribuir para a redução de florestas nativas em diversas regiões do Brasil. Assim, o objetivo deste trabalho foi analisar o grau de alteração antrópica da paisagem no município de Santa Fé do Araguaia/Tocantins, no período de 2009 a 2019. Para tanto, realizou-se levantamento bibliográfico em bases oficiais de consulta: SciELO e Portal de Periódico Capes sobre as alterações na paisagem, além da obtenção de forma gratuita das bases cartográficas do Instituto Nacional de Pesquisas Espaciais, na escala de 1:100.000, por meio do seu website. Essas bases foram recortadas, delimitando a área de estudo, utilizando os softwares livres QGis, versão 3.18 e Spring versão 5.4.3. Os dados analisados mostram uma redução da vegetação causada, principalmente, pela pecuária extensiva, que atualmente ocupa 75,65% do município estudado. Os tipos de vegetação Savana Florestada e a Área de Tensão Ecológica, com contato entre Savana e Floresta Ombrófila, tiveram suas áreas reduzidas a 0%, enquanto a Floresta Ombrófila Aberta Submontana teve uma redução de 12,14%. Diante dos resultados, é notável destacar a preocupação com o avanço do desflorestamento, uma vez que as florestas fornecem importantes funções para o equilíbrio dos ecossistemas.

With the intention of understanding the dynamics of cross-border health related migration movements, we sought to investigate the health-related movements that involved Brazilian cities located inside the border strip and neighboring countries. Therefore, we used data from the REGIC (Região de Influência das Cidades - Cities's Area of Influence) research (2018), that described pairs of cities (one Brazilian and one international) in which there were healthrelated movements. The data was treated and organized with the help of geotechnologies (QGIS and Google Earth Pro) to create indicators and a summary map. We observed that the Southern region is the Brazilian region with the most international health-related migration connections (39), while the mid-western and northern regions had approximately half that amount (19 each). The neighboring countries that are most involved with this phenomenon are Argentina, Paraguay and Uruguay, which where the other three founding members of the MERCOSUL, as well as Bolivia. It was also found that the currently available public data on cross-border health-related movements do not allow for a detailed analysis of the cross-border movements for accessing health services, which impacts the making of more specific public policy and planning by the Brazilian Public Health System (SUS) for this theme.

The traditions and customs of quilombola communities are fundamental for understanding the concept of human adaptability and landscape conservation. Thus, this study aims to investigate the landscape changes in the Turvo River Basin, in the municipality of Barra do Turvo/SP, investigating the forms and adaptation strategies created or adopted by the quilombola communities Cedro, Ribeirão Grande-Terra Seca and Pedra Preta-Paraíso in the period from 1990 to 2020, in order to generate information that will assist in the conservation of the natural components of the landscape, and in municipal environmental planning and management. For this, we used bibliographical research and life history in order to verify the quilombola trajectory and its relationship with the place of experience. Geotechnological tools were used to measure the Anthropogenic Transformation Index through vegetation cover and land uses. For the understanding of the society-nature duality, the study of the place and the quilombola way of life marked by the historical context of resistance and struggles for access to land and recognition are key points for diagnosis of the state in which the landscape is established. The state of the landscape of Little degraded, in the years analyzed implies the conservation measures developed by the quilombolas to maintain local diversity. Despite the oscillation of the index, without changing the state, it is necessary to develop mitigating measures with local society in order to conserve the landscape of the watershed, contributing to the maintenance of the biome in the Vale do Ribeira region.

Extreme hydrometeorological events have gained increasing visibility on public agendas in recent decades, given the material damage they cause and the population groups that are affected, especially those who live in the proximity of bodies of water. The study of these events, as well as their spatial distribution, allows us to identify areas with different levels of environmental criticality. The objective of this work is to analyze the characteristics of water risk in the lower reaches of the Napostá Grande stream basin (Argentina). The methodology included the statistical analysis of climatic, topographic, biological, and edaphic data. The results obtained showed that the areas that presented a high level of water risk were located in the northeast, northwest, south, and southeast of the study area; in the category of medium water risk, a large area of urban space was observed while the areas that presented low levels were located mainly in the north and east sectors. This information is key for the design and preparation of planning and land use planning proposals aimed at reducing the potential damage caused by the occurrence of potentially dangerous events such as floods, flooding, and overflows.

Studies focused on environmental characterization are essential for assisting in the planning of land use activities and management in watersheds. From this perspective, this study aims to characterize the physical-environmental elements of the landscape in the Turvo River Watershed in São Paulo, aiming to assist in the planning of land use activities and decision-making. Geotechnological tools were used for the creation of maps and tables of biophysical attributes, vegetation cover, and land use. In the watershed, the main economic activities are related to agriculture and livestock farming, which has been the most impactful category in Anthropogenic Uses over the years analyzed (1990-2020). The geological formations that predominated in the area were: Turvo-Cajati Formation (36.41%), Atubá Complex (28.20%), and the Unit of Banded Migmatitic Gneisses (13.38%). In geomorphological units, they were: Curitiba Plateau (56.30%) and the Ribeira Range (35.24%). In soil units, Cambisol (67.60%) with high erodibility and Neosol (26.96%) with very high erodibility. In terms of slope, the Undulating terrain accounted for 31.14%, and Strongly Undulating was 44.61%. In altimetry, the classes were 400-600 m (12.68%), 600-800 m (63.41%), and 800-1,000 m (10.94%). The environmental characteristics of the watershed indicate that land use restricts the use of agricultural machinery due to the mountainous formations in the area, as well as for conventional agricultural development. Therefore, it was concluded that there is a need for land use development planning to support municipal managers in decision-making. [ABSTRACT FROM AUTHOR]

No presente trabalho objetivou-se compreender a ocorrência integrada das inundações, bem como das intervenções antrópicas na bacia do rio Macabu, Rio de Janeiro, atentando para seus efeitos sobre o uso da terra e cobertura vegetal. Para tanto, criou-se um banco de dados georreferenciados multicriterial em ambiente SIG (ArcGIS 10.6.1), onde foram analisadas as variáveis de declividade, elevação, densidade de drenagem, precipitação e usos da terra para se gerar o modelo do risco socioambiental das áreas sujeitas às inundações, divididas em 4 classes: baixa ou nula, média, alta e muito alta. Juntas, as classes “alta e muito alta” somam 37,8% da bacia. Todos os usos da terra mapeados estão em áreas sujeitas a inundações, notadamente as áreas antrópicas não-agropastoris (78%) e as áreas naturais não florestadas (90,3%). Os resultados obtidos podem auxiliar o planejamento e ordenamento territorial-ambiental da bacia, ou de áreas em condições socioambientais similares.

En este trabajo se recoge una reflexión acerca del crecimiento exponencial que se está produciendo en el uso de las fuentes geohistóricas, y su relación con los cambios de paradigma que genera la tecnología. El recorrido por el papel que juega este amplio conjunto documental en la investigación lleva de forma irremediable a abordar aspectos relacionados con su tratamiento, una cuestión que se vinculará con la necesidad de establecer un contexto disciplinar. Y es que, ante la situación actual, y mirando al futuro, se hace necesario que la geografía histórica se recupere de forma preeminente como el marco teórico y epistemológico en el que se inserten las fuentes geohistóricas, con la finalidad de cohesionarlas con una teoría, unos métodos y unas herramientas. De esta forma, se acercará al lector a este conjunto documental y a la democratización de su uso. Así mismo, se muestra una revisión del cómo se ha investigado a la luz de las nuevas tecnologías. Finalmente, ligado a unas conclusiones formuladas, a modo de reflexión, se recogen los desafíos y retos más destacados, presentes tanto a escala nacional como internacional.

Estudos voltados para caracterização ambiental são essenciais para auxiliar no planejamento das atividades de uso da terra e manejos em bacias hidrográficas. Nessa ótica, este estudo tem como objetivo caracterizar os elementos físico-ambiental da paisagem na Bacia Hidrográfica do Rio Turvo/SP, visando auxiliar no planejamento das atividades de usos da terra e tomada de decisões. Foram utilizadas ferramentas geotecnológicas para a elaboração de mapas e tabelas dos atributos biofísicos, da cobertura vegetal e uso da terra. Na bacia, as atividades econômicas correspondem principalmente a atividade agropecuária, sendo esta, a mais impactante da categoria de Usos antrópicos nos anos analisados (1990-2020). As formações geológicas que predominaram na área foram: Formação Turvo-Cajati (36,41%), Complexo Atubá (28,20%) e a Unidade de Gnaisses Migmatíticos Bandados (13,38%). Nas geomorfológicas, foram: Planalto de Curitiba (56,30%) e a Serrania do Ribeira (35,24%). Nas unidades pedológicas o Cambissolo (67,60%) com alta erodibilidade e o Neossolo (26,96%) com muito alta erodibilidade. Na declividade, o relevo Ondulado (31,14%) e o Forte Ondulado (44,61%) e na altimétrica, as classes de 400├600 m (12,68%), de 600├800 m (63,41%) e de 800├1.000 m (10,94%). As características ambientais da bacia demostram que o uso da terra restringe o uso de máquinas agrícolas em função das formações montanhosas na área, assim como, para o desenvolvimento agrícola convencional. Portanto, concluiu-se que há necessidade de planejamentos do desenvolvimento dos usos da terra para subsidiar os gestores municipais na tomada de decisões.

Focusing on the approach of the municipal territory, many of the instruments pass on the environmental, economic and legal issues. Perhaps this is an exercise to achieve the goal of an instrument capable of promoting sustainable development at the municipal level. The objective was to identify the permeabilities between urban and environmental instruments in the municipal territory of Campo Grande, capital of the state of Mato Grosso do Sul. The methodological development was carried out in four stages: bibliographic and documentary survey to survey the state of knowledge; characterization of zones and recommendations of use of the Ecological-Economic Zoning of Campo Grande (EEZ/CG); Environmental zoning analysis of the review of the Environmental Urban Development Master Plan (PDDUA) de Campo Grande e; Proposed insertion of EEZ/CG zones in the Master Plan. In view of the instruments that demand Environmental Zoning, present in the Master Plan, zoning and Ecological-Economic Zoning (EEZ), environmental aspect, applied in the municipal scale, this work aims to propose the integration of Environmental Zoning in environmental and urbanistic aspects. The need to municipalize the instruments of territorial management are beyond urban planning and the role of the EEZ/CG in the territorial planning, represents a path without return, and occupying the leading role for the institution of the municipal environment policy, to base the municipal system of conservation units and the management of water resources in the municipality. This essay demonstrates that the legal framework must be strengthened in the moment of positively subsidizing the manager with the purpose of justice and clarity, seeking to ensure the quality of life for all and to promote a healthy and balanced environment.

The availability of quality water for various activities has been decreasing across the planet, as a result of human actions and degrading natural events. In this context, it appears that river basins are considered the most appropriate units for managing natural resources in the ecosystem, as they present different landscape characteristics that influence the selection of soil and water management practices. To this end, knowledge about the hydrological behavior of the Gavião River Basin was used using orbital data and geoprocessing techniques together with statistical analyzes with the aim of characterizing the environment and morphometric characteristics. Analysis of the data and results obtained for the Gavião River Watershed allowed us to conclude that the organization of the drainage network has an area of approximately 10,112 km² and a perimeter of 781 km. The slope in the range 3-8% corresponds to 29.61% of the basin area, considered moderately inclined. The Gavião River was approximately 340 km long. According to the results, it can be stated that the study area appears to be less susceptible to flooding under normal precipitation conditions, that is, excluding events of abnormal intensities, due to the fact that the compactness coefficient presents a value far from of the unit and, regarding its form factor, display a low value. Thus, there is an indication that the basin does not have a circular shape, and therefore has a tendency towards an elongated shape. The data showed approximately 188% of the study area is covered by forest formation, 56.53% occupied by savanna formation, and 36.49% with the use of pasture. The information obtained enables decision-making for the conservation and adequate management of water resources in the region. [ABSTRACT FROM AUTHOR]

This paper makes a geomorphometric analysis of the high wathershed of Ribeirão Santa Marta (BHRSM), with the objective of evaluating the water behavior of this hydrographic unit, which is quoted as a future source of water supply for the city of Iporá (GO). The study was carried out using mathematical modeling, remote sensing products and geoprocessing techniques. The data used in the study were obtained from the Digital Elevation Model (DEM) of the Brazilian Geomorphometric Database (TOPODATA). Among the various geomorphometric indices described in the literature, those that best portray the infiltration and surface runoff of rainwater were selected. The organization of the data, the geoprocessing techniques and the elaboration of the cartographic products of the hydrographic basin were carried out using the Geographic Information System (GIS) QGIS. The results of the indices, analyzed together, indicated that the BHRSM is more favorable to surface runoff. This shows that the basin has a more active hydrological behavior, that is, the water flows more easily, being unfavorable for recharge and water storage. Thus, the data indicate that the BHRSM may have a compromised permanence flow to meet the public supply of Iporá (GO) in the future. [ABSTRACT FROM AUTHOR]

The need to increase forest enterprises' productivity has demanded higher levels of mechanization. The objective of this study was to evaluate the suitability of areas in Espírito Santo State to implement mechanized wood harvesting using a short log system. To prospect suitable areas for mechanization, an algebra map of Eucalyptus edaphoclimatic zoning, land use and occupation, slope, conservation units and their respective buffer zones was performed. Thus, suitability zones were defined based on edaphoclimatic conditions for evaluated species, with temperatures between 19 and 26°C, water deficit from 30 to 210 mm and annual average rainfall between 900 and 1800 mm defined as suitable. Land use and occupation were classified as fit, fit with type II limitation, fit with type III limitation and unfit. For slope classes, three categories were created: fit (0 - 27°), fit with limitation type I (27.1 - 35°) and unfit (> 35°). Results showed that the State has 39.45% of its entire area able to implement mechanized wood harvesting for Eucalyptus, while 47.91% of it is unfit. Based on the results, the authors concluded that the Northeast micro-region stood out with large, suitable areas for Eucalyptus harvest mechanization and that the employed methodology has potential for use and adaptation in other study areas around the world.

The present research seeks to study environmental changes due to the advance of agribusiness on the territory of the Morro de São João Quilombola Community (CQMSJ), in the State of Tocantins, and its repercussions on surface temperatures. Large-scale commercial agriculture, in some cases, disregards in its practice the impacts it causes to traditional communities that live in the vicinity of large agricultural enterprises. The community realizes that it has experienced several environmental changes in its surroundings, due to the replacement of native vegetation by commercial crops, in the place that was previously part of its original territory. The methodological procedures were based on the use of geotechnologies for studies of themes related to the climate. For this, the terrestrial surface temperature (TST) was estimated over the territory that covers the CQMSJ in the dry winter season and in the rainy season in spring, through satellite images of the Landsat 7 and 8 series, in scenarios of observation of 1999/2000 and 2019/2020, referring to two moments: respectively, before and after the agricultural expansion in the study area. The results indicate that there was a surface temperature variation mainly associated with changes or alterations in land use and occupation. The increase in TST was more expressive in areas that are currently destined for agricultural production along the lines of agribusiness. The results point to probable consequences of intensive exploration of this traditional territory inserted in the Cerrado biome, especially regarding its microclimatic aspects, with possible implications for the life of a quilombola community.

Toponymy is a discipline that studies the proper names of places. In Geography, toponyms are important because they provide information about a specific space. At present, georeferenced territorial information in digital format is of growing relevance. Therefore, the present work aims to apply geotechnologies to the treatment of toponyms at scale 1:25.000 for the sector of Ingeniero White, covered by the 3963-17-1 Bahía Blanca chart, prepared by the Instituto Geográfico Nacional (I.G.N.) (National Geographic Institute). For this purpose, a quali-quantitative methodological approach was applied, which included the gathering, selection and analysis of information, the creation of an alphanumeric database and the use of geotechnologies for the spatial treatment of toponyms and their information by means of a Geographic Information System (G.I.S.). The result was the creation of a dynamic consultation system through the use of pop-up windows that allow interaction with the geolocalized toponyms. It can be concluded that the creation of a database of toponyms and its visualization through a G.I.S. allows for the presentation of information and its consultation in a dynamic way to analyze information about changes in the names of places, in this case of Ingeniero White.

Esse artigo faz uma análise geomorfométrica da alta Bacia Hidrográfica do Ribeirão Santa Marta (BHRSM), com objetivo de avaliar o comportamento hídrico dessa unidade hidrográfica, que é cotada como futura fonte de abastecimento hídrico da cidade de Iporá (GO). O estudo foi realizado com uso de modelagem matemática, produtos de sensoriamento remoto e técnicas de geoprocessamento. Os dados empregados no estudo foram obtidos a partir do Modelo Digital de Elevação (MDE) do Banco de Dados Geomorfométricos do Brasil (TOPODATA). Dentre os diversos índices geomorfométricos descritos na literatura, foram selecionados os que melhor retratam a infiltração e o escoamento superficial da água das chuvas. A organização dos dados, as técnicas de geoprocessamento e a elaboração dos produtos cartográficos da bacia hidrográfica foram feitas por meio do Sistema de Informação Geográfica (SIG) QGIS. Os resultados dos índices, analisados conjuntamente, indicaram que a BHRSM é mais favorável ao escoamento superficial. Isso evidencia que a bacia possui um comportamento hidrológico mais ativo, ou seja, a água escoa com maior facilidade, sendo desfavorável para a recarga e armazenamento hídrico. Dessa forma, os dados indicam que a BHRSM pode ter a uma vazão de permanência comprometida para futuramente atender o abastecimento público de Iporá (GO).

O custo de frete da soja, commodity que responde por 14% da exportação nacional, corresponde a 80% do custo total de seu transporte. Redução dos custos logísticos são previstas no Plano Nacional de Logística 2025 através de investimentos nas infraestruturas de transporte, contudo, os métodos utilizados para dar suporte e justificar os investimentos não são claros. Este trabalho investiga as rotas de exportação de soja entre os municípios produtores e os principais portos de destino utilizando geotecnologias e simulação para cenários preditivos. A pesquisa abrangeu todo o território nacional e foi alimentada por dados públicos oficiais considerando a infraestrutura de 2020 e 2025 na criação de um modelo multimodal, multiorigem e multidestino desenvolvido em plataforma livre. Os resultados qualificam e quantificam a redução do custo do transporte da soja. O estudo beneficia a sociedade, não apenas pela transparência dos dados, mas também por antecipar cenários que podem subsidiar políticas públicas.

Este trabalho objetivou estimar a perda de solos em propriedades rurais registradas no cadastro ambiental rural do município de Alagoa Nova-PB, de acordo com as classes de solos existentes. A EUPS foi utilizada para estimar a quantidade de perda de solo para as classes de solo. O valor do fator R utilizado foi de 6394,43 MJ.mm/ha.h/ano para todas as áreas e classes de solo; o fator K utilizado foi o tabelado para cada classe de solo; o fator topográfico (LS) foi calculado de acordo com a declividade e comprimento de rampa nas propriedades por meio de Modelo Digital de Elevação; e o valor de CP utilizado foi por meio de valores atribuídos ao uso e ocupação do solo. Foi estimada uma perda para o Argissolo Vermelho de 441,68 t/ha/ano e de 298,84 t/ha/ano para o Neossolo Regolítico, ambos com taxa de erosão classificada como Muito Forte. Já o Argissolo Vermelho Amarelo (126,11 t/ha/ano) e o Neossolo Flúvico (187,53 t/ha/ano) foram classificados com taxa de erosão Forte. Os valores de perdas de solo verificados para todas as classes de solo superam os níveis de tolerância de perdas de solo.

We aim to demonstrate the methodology used in the critical analysis of the municipality of Cachoeira do Sul (state of Rio Grande do Sul, Brazil), which had its Master Plan recently revised and approved, verifying the urban practices implemented until then in the city. For the application of the methodology, data surveys, studies and mappings were carried out with systematization of a geographic database in a GIS environment, as well as on-site technical visits and application of questionnaires to apprehend the opinion of the population on important subjects in the development of the municipality, consolidating the technical and community readings of the territory. From these data, always guided by group discussions, we developed diagnosis, prognosis, scenarios, and guidelines, macrozoning and intervention proposals, filling gaps in the Master Plan in relation to planning with the landscape, the open space system and the development of the city and the region. Among the developed proposals, those related to urban mobility were highlighted in this article - urban and rural cycle lanes. [ABSTRACT FROM AUTHOR]

Environmental complaints are considered an effective tool for controlling and monitoring the environment, since they come from the community and encourage technical analysis by public agents. Remote sensing, combined with the denouncement tool, can act as a tool to help environmental control bodies, in the assessment of areas impacted by anthropic activities and aid in decision-making. Thus, the objective was to evaluate the municipality of Passo Fundo according to environmental complaints, in different neighborhoods combined with the use of remote sensing. The analysis used data from environmental complaints received in 2019, 2020 and 2021 by the Municipal Environment Secretariat. As a result, it is highlighted that the most recurrent complaints correspond to deficiencies in basic sanitation (sanitary sewage, solid waste, and water) and animal husbandry in urban areas, with 45.62% and 13.17%, respectively. The mapping of the data allowed us to observe that the most affected areas are in the center of the city, even though the periphery region faces the greatest lack of services and necessary infrastructure for the promotion of basic conditions of health and environmental well-being. The geospatialization of environmental complaints, therefore, makes it possible to identify which regions of the municipality have the greatest deficiencies in terms of the environmental issues denounced by the community and thus facilitate the environmental planning of the municipality.

Models of environmental fragility analysis help us to spatialize areas with greater and lesser degrees of fragility to erosive processes and the understanding about the relationship among these processes and human activities. This study aimed to evaluate three sub-basins of the Taquari River, in Mato Grosso do Sul State, by integrating of information due to natural erosion ability and erosion processes generate by land using, to support socio-environmental planning actions to an adequate using of natural resources and conservation of its biodiversity in the Alto Taquari basin. The study has been based in cartographic products obtained from satellite Sentinel 2 images, vector soil data, rainfall, priority areas for biodiversity conservation and terrain slope available onto Geographic Information System (GIS). The three sub-basins have presented Pasture as the main form of using and different degrees of anthropism. Only Córrego do Sítio headwaters which are located inside an Environmental Protection Area (APA) have been preserved. In view of the results that were obtained in the present study, it has been considering necessary for recovering areas of permanent preservation and in areas which bordering the stream at the Veado and Criminoso sub-basins, once given the natural fragility to the erosive processes that exist in this region, and also the protection of important remnants of Cerrado vegetation which must have effective conservation measures to maintain the soil, water and ecosystem services qualities arising from local biodiversity. By considering the socio-environmental characteristics from Coxim municipality, a sustainable tourism should be indicated, since it is one of the few remaining areas of Cerrado Biome in this region with its natural characteristics suitable for the development of this economic activity (native vegetation and preserved water resources), which might represent an important increasing to the population's income.

This study described the spatial and temporal profile of fires in an area proposed for creating a Conservation Unit (UC) in the Microregion of Serra de Carrancas, Minas Gerais. Images from the LandSat 5 and 8 satellites, TM and OLI sensors, were used between the years 2002 and 2015. The Normalized Difference Vegetation Index (NDVI) and the NDVI difference were calculated to detect burned areas. In addition, we used a density point approach to characterize the spatial distribution of the fi res. The land cover classes analyzed were a) agriculture and pasture; b) native forests; c) planted forests; and d) cerrado. To analyze the fire-fighting efficiency, the polygons were grouped into the following size classes: I (<0.1); II (0.1 - 4); III (4.1 - 40); IV (40.1 - 200); V (> 200) hectares. We used the variables accumulated precipitation, the average temperature, and relative humidity to analyze the fire occurrences in the temporal aspect. We detected 2,747 polygons of burned areas, totaling 18,320.14 hectares. From this total, 758 polygons occurred within the UC with an area of 6,696.74 ha. The months with the highest records were August, September, and October. The years 2003, 2009, 2011 and 2014 had the highest occurrences and burned areas in the analyzed period. The grouping in size classes showed a higher frequency of burned areas in classes II and III. Therefore, the implementation of this UC should accompany a policy for preventing and fighting forest fires to preserve the ecological integrity of the region. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate and map the potential of agricultural production of cassava using geotechnologies for the basin of the middle course region of Paraíba river. SPRING was used to construct the maps of irrigation potential and water retention capacity of the soils and generate the partial map through matrix crossing. Annual average rainfall data were used to construct the climate condition map. Subsequently, LEGAL was used to generate the agricultural production potential map through matrix crossing between the partial map and the climate scenario map. For cassava crop, the following climatic conditions were found: Full in 13.67% of the basin's total area; Full with prolonged rainy season in 3.55%; Moderate due to water excess was not identified; Moderate due to water deficit in 21.03%; and Unsuitable due to severe water deficit in 61.75%. Regarding the potential of irrigated agricultural production of cassava crop, there was no Very High or High, and it was classified as Medium in 3.19% of the area, Low in 5.09% and Very Low in 91.72%. Therefore, irrigated cassava cultivation is not recommended in the watershed of the region of the middle course of the Paraíba River. [ABSTRACT FROM AUTHOR]

This research aimed to map flood-prone areas in the Quintino Basin, Belém do Pará, which faces adverse events such as floods, putting the population in vulnerable and risky situations. To generate the risk, the threat analysis was cross-referenced with vulnerability. The results revealed that the flood hazard area corresponds to 40.33% of the basin's total area, with 6.4% classified as high flood risk, 15.2% as moderate flood risk, and 18.7% as low flood risk. The neighborhoods of Jurunas (91.8%) and Condor (61.6%) were the most affected ones, with a larger extent of affected areas. Those neighborhoods also showed high socio-economic vulnerability, evidenced by indicators such as child population, illiteracy rate, and income. The risk analysis and mapping indicated that 40.33% of the basin's territory is affected by the risk zone, with Jurunas (91.8%) and Condor (61.6%) neighborhoods presenting the highest percentage of risk due to the previously mentioned high socio-economic vulnerability in those areas.

The Vargem das Flores basin in the municipality of Contagem/mg is the scene of intense conflicts related to land use and divergent policies on territorial planning and environmental protection, because the area is protected by environmental legislation. Downstream of the basin there is a dam for the formation of the Vargem das Flores reservoir that supplies the urban population of the Belo Horizonte Metropolitan Region. The prevalence of municipal interests over metropolitan interests put the remaining green areas, watercourses, and drainage channels at risk due to the possibility of urban expansion in the area. In this context, this study sought to map the possibility of reconciling urban expansion and environmental conservation in Vargem das Flores and to identify possible conflicts of interest in the basin. The multi-criteria analysis method was used, and it resulted in three syntheses: urban expansion, environmental conservation, and integration synthesis. After building the syntheses, an alternative approach was built to identify land use skills based on the master plan, which resulted in a mapping that sought to meet the needs identified in the territory. The results revealed that the proposed zoning in 2018 puts at risk natural resources fundamental to the existence of the reservoir. The aptitude synthesis adapted to the plan presented an alternative that reconciles the existing conflicting interests. [ABSTRACT FROM AUTHOR]

As enchentes, inundações e erosões urbanas são problemas advindos do impacto da antropização, que podem resultar de ocupações irregulares e ausência planejamento territorial, prejudicando a comunidade, em especial nas áreas com topografia acidentada e várzeas com jusante de aluvião. Nessas regiões, as inundações prejudicam a mobilidade dos moradores e colocam em risco sua integridade física. O principal objetivo deste estudo foi elaborar um mapa de risco à inundação na Unidade de Negócio Oeste (MO) da Companhia de Saneamento Básico do Estado de São Paulo (Sabesp), pelo uso do software livre QGIS. A metodologia utilizou a técnica Analitycal Hiearchy Process (AHP), baseando-se nos seguintes critérios: pedologia, geologia, uso e ocupação da terra, altimetria e declividade do terreno. Foram elaborados mapas para cada critério, respeitando-se as notas de influência dos intervalos e os pesos estatísticos a partir da análise hierárquica. A partir da álgebra de mapas no Sistema de Informações Geográficas (SIG), obteve-se como resultado o mapa final de riscos a áreas de alague. A MO obteve a predominância de risco regular com 52,5% referente a uma área de 53 mil hectares, sendo que o risco de maior valor observado teve um percentual de 13,6%. A disposição geométrica das zonas de risco ficou condizente com as áreas da realidade, como por exemplo o bairro do Rochdale, em Osasco, e os vetores dos córregos inundáveis. A metodologia proposta pode ser utilizada como instrumento de suporte para elaboração de projetos ambientais e planeamento urbano que objetivem controlar as inundações e alertar aos moradores que residem nessas áreas.

A bacia de Vargem das Flores no município de Contagem/MG é palco de intensos conflitos relacionados ao uso do solo e políticas divergentes referentes ao ordenamento territorial e proteção ambiental, uma vez que a área é protegida por legislação ambiental. A jusante da bacia encontra-se um barramento para a formação do reservatório Vargem das Flores, que abastece a população urbana da Região Metropolitana de Belo Horizonte. A vigência dos interesses municipais sobre os interesses metropolitanos colocou as áreas verdes remanescentes, cursos d’água e calhas de drenagem em risco pela possibilidade de expansão urbana na área. Nesse contexto, o presente estudo buscou mapear em Vargem das Flores a possibilidade de compatibilização entre expansão urbana e conservação ambiental e identificar possíveis conflitos de interesse na bacia. Utilizou-se o método de análise multicritério que resultou em três sínteses: expansão urbana, conservação ambiental e integração. Após a construção das sínteses, foi construída uma aproximação alternativa com o objetivo de identificar aptidões de uso do solo com base no plano diretor, resultando em um mapeamento que buscou atender as necessidades identificadas no território. Os resultados revelaram que o zoneamento proposto em 2018 coloca em risco recursos naturais fundamentais para a existência do reservatório. A síntese de aptidão adaptada ao plano apresentou uma alternativa que compatibiliza os interesses conflitantes existentes.

A atividade hortifrutícola tem ganhado nos últimos anos maior visibilidade por meio de programas de estímulo estadual, pois é uma importante fonte de emprego e renda para a economia de muitos municípios, já que o estado do Rio Grande do Sul (RS) figura como 4.º produtor nacional de frutas. Contudo, as más condições das estradas rurais vêm acarretando prejuízos, o que afeta a renda auferida pelos hortifruticultores. As condições das estradas, via de regra, dão-se em virtude da interação do homem com o espaço geográfico e com a sociedade, porque este impacta o meio, quando pressiona a abertura de novas estradas, as quais encontram no relevo algumas dificuldades de trafegabilidade. Nesse sentido, este artigo tem como objetivo caracterizar e avaliar em que medida os atributos do relevo impactam o sistema viário e, consequentemente, o escoamento da produção nos municípios de Nova Esperança do Sul e Santiago – RS. Buscou-se, através do software livre QGIS, versão 3.4 LTR “Madeira”, aplicar uma série de ferramentas computacionais para a extração das variáveis contidas no MDE para computar as impedâncias. Inicialmente, realizou-se uma análise da produção hortifrutícola, demonstrando a necessidade de transportes. Além disso, observou-se que no período de 12 anos houve um aumento de 4,76% na produção, justificando, assim, a necessidade de um modal capaz de satisfazer tais necessidades. Por outro lado, observou-se que praticamente 80% das estradas nos respectivos municípios não são pavimentadas, sofrendo com buracos, erosões, ausência de drenagem, etc. impactando a trafegabilidade dos produtores e da comunidade em geral.

A pandemia de Covid-19 que iniciou em 2020 trouxe a necessidade de adaptação para práticas educativas cotidianas que antes eram realizadas em modo presencial. O uso das geotecnologias, atreladas às ferramentas digitais de comunicação, foram fundamentais para a continuação e desenvolvimento de atividades acadêmicas, que se viram forçadas a migrar para o meio digital. O objetivo desse estudo foi apresentar as potencialidades e fragilidades do uso dos StoryMaps como alternativa de imersão virtual, a partir do desenvolvimento de atividades remotas (no Campus Seropédica da Universidade Federal Rural do Rio de Janeiro (UFRRJ) e na Floresta Nacional Mário Xavier (Flona MX)), com a realização de três projetos para a comunidade de Seropédica-RJ e adjacências, por meio dos geopasseios virtuais. A produção de instrumentos didáticos para a elaboração de oficinas virtuais tornou possível a realização das aulas de educação ambiental com imersão espacial, através de adaptações durante o período de ensino e atividades de extensão remotas. Os resultados alcançados pelas atividades remotas de extensão demonstraram que a metodologia aplicada é uma alternativa de imersão virtual. O uso do StoryMaps reproduziu o território de maneira imersiva, sobretudo para o reconhecimento das trilhas e pontos temáticos georreferenciados, com interatividade para os participantes. As fragilidades encontradas foram decorrentes das dificuldades de públicos específicos, como pessoas com baixa visão e discentes excluídos digital e socialmente, que não possuem os dispositivos eletrônicos compatíveis e o livre acesso à internet. Palavras-chave: Geovisualização; Geotecnologias; Educação Ambiental Virtual geosightseeing as an immersion alternative at UFRRJ campus and Mário Xavier National Forest during the pandemic Abstract: The Covid-19 pandemic began in 2020 and brought a need to adapt to everyday practices previously done in person. Using geotechnologies linked to digital communication tools was fundamental for continuing and developing academic activities, which were forced to migrate to the digital environment. The objective of this study was to present the strengths and weaknesses of using StoryMaps as an alternative for virtual immersion, based on the development of remote activities (at the Seropédica Campus of the Federal Rural University of Rio de Janeiro (UFRRJ) and in the Mário Xavier National Forest (Flona MX)), with the realization of three projects for the community of Seropédica-RJ and surroundings through virtual geowalks. The production of didactic instruments for elaborating virtual workshops made it possible to carry out environmental education classes with spatial immersion through adaptations during the teaching period and remote extension activities. The results achieved by the remote extension activities showed that the methodology applied is an alternative to virtual immersion. The StoryMaps reproduced the territory in an immersive way, especially for recognizing georeferenced thematic trails and points, with interactivity for the participants. The weaknesses observed resulted from the difficulties of specific audiences, such as people with low vision and students excluded both digitally and socially, which do not have electronic devices and access to free internet.

As geotecnologias têm se mostrado importantes e promissoras ferramentas para melhoria da gestão pública, porém são raras as publicações sobre seu uso nos municípios brasileiros. Esta pesquisa realizou um levantamento sobre o uso das geotecnologias e a existência e uso de bases cartográficas nos municípios do estado do Espírito Santo através de questionários respondidos pelas prefeituras. Os resultados mostraram que há uma forte demanda por atualização de bases cartográficas e que o uso das ferramentas de geoprocessamento pode ser muito ampliado. Foram apontados caminhos e estratégias para essa ampliação, além de algumas experiências dos municípios e oportunidades de atuação para os profissionais e instituições da área de geotecnologia. O trabalho pode ser usado para traçar um panorama do uso de geotecnologias nos municípios brasileiros e auxiliar a construção de projetos voltados para esses órgãos públicos.

Human activities modify the natural characteristics of numerous watersheds worldwide. Google Earth Engine provides tools for the analysis of land use and natural resources. In this work, we classify current land use and cover in the Sucuru watershed, Paraíba, Brazil. We compared the accuracy of five supervised classification algorithms of Google Earth Engine. Classifiers based on Decision Trees, such as the Classification and Regression Trees (CART) and Random Forest (RF), showed the best accuracy and visual inspection values. The Google Earth Engine is a powerful tool for analysis of large-scale environmental data, monitoring land use changes, and providing information for sustainable management. [ABSTRACT FROM AUTHOR]

The horticultural activity has gained in recent years greater visibility through state stimulus programs. Horticulture is an important source of employment and income for the economy of many municipalities since the state of Rio Grande do Sul is the 4th largest national fruit producer. However, the poor conditions of rural roads have been causing losses, affecting the income earned by horticulturalists. The road conditions are usually due to the interactions of man with the geographic space and society because it impacts the environment when pressing the opening of new roads. These roads have some difficulties in terms of mobility. In this sense, this work aims to characterize and evaluate to what proportion that attributes of the terrain impacts road system and the flow of production in the municipalities of Nova Esperança do Sul and Santiago, RS. It was sought through the free software QGIS version 3.4 LTR "Madeira" to apply a series of computational tools for the extraction of variables contained in the MDE to compute the impedances. Initially, an analysis of horticultural production was made, demonstrating the need to transpose and it was observed that in the period of 12 years an increase of 4.76% in horticultural production, thus justifying the need for a modal capable of satisfying such needs. On the other hand, it was observed that 80% of the roads in the respective municipalities are not paved, suffering from holes, erosion, lack of drainage, etc. impacting the trafficability of producers and the community in general.

Forest fires generate problems at various scales, and in Conservation Units they promote degradation of vegetation, significant impacts on biodiversity, financial losses and even loss of life. In this context, the aim of this article to analyze and map the outbreaks of fire in the Ilha Grande National Park (PNIG), in August 2019, as well as to identify the evolution of the burned area over the period. For the mapping of the burnt area daily, images from the AQUA M-T satellite were used together with the heat sources acquired from the Burning Database available on the INPE website. And, to show the relationship between the burned area and the meteorological variables, data from the Itaquiraí - MS meteorological station were used. The results show that in the analyzed period 85% of the PNIG were burned, with emphasis on 14/09 with 336.44km² of affected area. It was also possible to verify that the meteorological variables, mainly the wind speed, have a direct relationship with the burned area, that is, the higher the wind speed, the greater the area affected.

The objective of this work was to investigate the degradation of Permanent Preservation Areas to identify forest fragments priority to recomposition in the municipality of Nova Marilândia-Mato Grosso, aiming to contribute, from the data and information generated, in the proposition of actions aimed at maintaining the landscape for the gene flow of the biota. For the definition of the categories of restoration priority, the Integral Connectivity Index was applied in the degraded Permanent Preservation Areas, with its IICflux (measurer of gene/environmental flow possibility) and IICconnector (measurer of node importance as the only connection among other fragments), derived from Graph Theory. In the municipality, the most expressive class is pasture (744.22 km²), surpassing the areas of Forest Natural Vegetation (687.23 km²), Savannah Formation (311.46 km²), Agriculture (157.68 km²) and Anthropic Uses (4.21 km²). Despite this scenario identified in the context of the municipality, the Permanent Preservation Areas are mostly preserved, and 1,706 fragments to be restored are identified; of these, 1,594 with low priority level, 102 with medium and 10 with high. Therefore, simple management measures such as isolation of degraded Permanent Preservation Areas, favoring fragments of high and medium priority of restoration, can provide opportunities for natural forest regeneration, restoring the function of genetic displacement of the local biota in the landscape without the need for high financial investments.

COVID-19Las ciudades son los focos de propagación del COVID-19, por lo que el acelerado crecimiento urbano, el déficit habitacional y la falta de acceso al agua y saneamiento pasan a ser problemáticas centrales. Lo cierto es que más de la mitad de la humanidad vive en zonas urbanas y el mayor crecimiento se produce en América Latina con lento crecimiento económico, desigualdades sociales y degradación ambiental. Ante esta realidad, estrechamente vinculada al cambio climático, se plantean posibles escenarios vinculados al hábitat. Tres conceptos son claves para la elaboración del marco teórico, el territorio, espacio complejo y objeto de análisis y de intervención del Ordenamiento Territorial, la seguridad humana y la gobernanza, temas en los que las Tecnologías de Información Geográfica pasa a ser fundamentales para analizar y diagnosticar situaciones referidas a las condiciones de vida de la población, aplicar técnicas prospectivas y llegar a la propuesta de acciones que permitan disminuir el margen de error en la toma de decisiones. A partir del desarrollo de estos temas se llega a la conclusión que se necesitan cambios estructurales para aumentar la seguridad y disminuir la vulnerabilidad ante amenazas como el COVID-19.
