Resumo: Este trabalho é parte do estudo sobre as diatomáceas perifíticas presentes no rio das Pedras, Guarapuava, no estado do Paraná, Brasil, e resultou na identifi cação de 35 táxons infragenéricos, distribuídos em 12 gêneros e seis famílias. Foram considerados táxons constantes: Frustulia saxonica Rabenhorst, Gomphonema gracile Ehrenberg e Gomphonema parvulum (Kützing) Kützing. A análise da comunidade diatomológica forneceu informações das condições ecológicas, sendo que a predominância de espécies eutrófi cas revela águas ricas em substâncias nutritivas, indicando que o sistema encontra-se alterado devido ao efeito causado por início de degradação de compostos orgânicos lançados no corpo d'água. Palavras-chave: Bacillariophyceae. Diatomáceas. Perifíton. Rio das Pedras. Abstract: This work is part of the study of periphytic diatoms in the rio das Pedras, located in Guarapuava, state of Paraná, Brazil, which resulted in the identifi cation of 34 infrageneric taxa distributed in 12 genera and six families. The following taxa were considered frequent: Frustulia saxonica Rabenhorst, Gomphonema gracile Ehrenberg, and Gomphonema parvulum (Kützing) Kützing. This diatomological analysis provided information on the ecological conditions of the river, while the predominance of eutrophic species reveals that its waters are rich with nutritive substances. This indicates that the system is altered due to effect of the beginning of degradation of organic compounds degradation thrown in the river.
A estrutura da comunidade de macroinvertebrados aquaticos do Rio Verde (em Ponta Grossa, PR, Brasil) foi estudada, objetivando avaliar o estado de conservacao deste corpo d’agua. Entre dezembro de 2006 e maio de 2007, os macroinvertebrados foram coletados em sedimentos e macrofitas marginais. Diversas medidas fisico-quimicas, bacteriologicas e bioindicadoras (como indice de diversidade de Shannon-Wiener, % de EPT e % de Chironomidae) foram avaliadas. Foram capturados 1926 exemplares, pertencentes a 47 familias de platelmintos, anelideos e artropodes. Os insetos representaram 88,4% do total de individuos amostrados, com 41 familias. Nos cinco pontos de coletas e de acordo com a analise de agrupamento, pelo coeficiente de distância de Bray-Curtis, observou-se diferenca na composicao da macrofauna bentonica, como reflexo da eutrofizacao gradativa do rio, a medida que ele atinge a area urbana da cidade.
O espaco urbano sofre constantes transformacoes promovidas por diversos fatores e agentes. Cidades tendem a crescer e a se expandirem direcao a areas sem a presenca de edifi cacoes e infraestruturas. Em Irati, principalmente nos ultimos cinco anos, foram notorias as modifi cacoes ocorridas, principalmente no bairro Alto da Gloria, em virtude da instalacao de infraestruturas e equipamentos de uso coletivo que sao fatores de atracao e valorizacao dos terrenos. Diante disso, e com base no respectivo bairro, buscamos compreender a especifi cidade do crescimento de Irati, as diferentes rendas extraidas dos terrenos e a especulacao imobiliaria presente em Irati.
Entre o final dos anos 1980 e durante os anos 1990 acontece uma intensa abertura da economia brasileira ao comercio internacional, (re)surgindo assim a questao da organizacao do territorio fundamentada na procura da otimizacao e da fluidez, de forma a intensifi car a circulacao de mercadorias e de informacoes, a especializacao da producao e a intensificacao da divisao do trabalho. A logistica territorial volta a frequentar a agenda politica nacional e regional como forma de trazer maior competitividade as empresas, como no caso dos projetos do CLIA – Centro Logistico Industrial Aduaneiro de Ponta Grossa - e do Aeroporto de Cargas de Tibagi, na regiao dos Campos Gerais do Parana. Neste artigo sao demonstrados os limites destes projetos segundo os conceitos de territorio empregados na Geografia.
A populacao de Anastacio (MS) e composta por inumeros migrantes, e, portanto, constitui-se em uma cidade culturalmente heterogenea que apresenta caracteristicas especifi cas desses migrantes, mas tambem o resultado da aculturacao entre as culturas exogenas e a local. O estudo propoe a analise da identidade cultural de Anastacio a partir da compreensao das manifestacoes culturais que fazem parte da construcao da identidade cultural e tambem dos processos dialeticos entre o local e o global, bem como da dinâmica entre territorios e as transformacoes que as culturas apresentam na localidade.
O objetivo desse trabalho foi analisar a dinâmica do uso e ocupacao da terra da bacia hidrografica do arroio Olarias no municipio de Ponta Grossa - PR, entre 1995 e 2005. Para identificacao das classes de uso da terra, utilizou-se o Manual Tecnico de Uso da Terra do Instituto Brasileiro de Geografia e Estatistica - IBGE (2006), cujas classes elencadas para este estudo foram: urbano, floresta, agricola, campestre e reflorestamento. A elaboracao dos mapas de uso da terra utilizou como ferramentas os recursos oferecidos pelas geotecnologias para manipulacao, atualizacao e espacializacao das classes. Por ser uma bacia hidrografica com ocupacao predominantemente urbana, a classe floresta apresentou uma reducao de area de 8,24%, no periodo analisado, sendo substituida pela expansao urbana e agricultura. A classe agricola apresentou uma pequena reducao no periodo estudado, o que demonstra que esta atividade ainda e expressiva mesmo em uma bacia urbana. A classe reflorestamento apresentou a mor area de uso identificada neste estudo e tambem sofreu reducao de 1,42% sendo substituida pela expansao do uso urbano, o que aponta a possivel erradicacao dessa atividade para os proximos anos.
The graphic representations have privileged space in the journeys made by naturalists since the Eighteenth century and they are fundamental elements of the geographical analysis. The main goal of this paper is to reflect on the illustrations that composed geographies of Brazil brought by the Philosophical Journey of the naturalist Alexandre Rodrigues Ferreira in the Eighteenth Century. First, it is presented the relevancy of the expeditions taken by naturalists as well as the importance of the images produced by such expeditions in the consolidation of Geography as a discipline. Next, it is discussed the journey made by Alexandre Rodrigues Ferreira in his Philosophical Expedition throughout Brazil. Lastly, it is analyzed the creation of images and imaginaries about Brazil at the time the graphic representations were produced.
The world is experiencing a moment of apprehension, which began in late 2019 and extended throughout the years 2020/21 which corresponds to the pandemic period of Covid 19. The disease arrived in Brazil in late February and spread all over the country. In Ponta Grossa, it arrived a few months later and the first case of
community transmission occurred on 05/26/2020. From this date on, it was possible to establish correlations between the climate and Covid 19, considering air temperature (maximum, average, and minimum) and solar radiation, the main goal of this paper. With the elaboration of graphs and statistical treatment of the data, it was possible to
determine the correlation between climatic variables and the new cases of Covid 19. It should be noted that it is necessary to continue the research to better understand the moment we are living and the mentioned relationships.
The sedimentary layers of Anitápolis, Santa Catarina, were the subject of relevant discussions about age and paleoenvironment in the first half of the 20th century. Today they are correlated to the ritmites from Itararé Group, but some of the fossils that are part of these studies were not subsequently revised. This is the case of Oliveirania santa catharinae (sic) Maury 1927, a species originally attributed to annelids, and the ichnofossils attributed to it by association. The Annelida fossils were considered here as pseudofossils of inorganic origin. The ichnofossils attributed to Oliveirania were redescribed as a new ichnospecies, Pterichnus mauryae isp. nov., possibly related to the activity of crustaceans. This is the first occurrence of Pterichnus in Brazil and the oldest in the world.
Para construir sua obra, a autora desenvolve um metodo que resgata, atraves da memoria dos faxinalenses, as relacoes cotidianas da festa, do trabalho, do lazer, dos encontros e dos desencontros, da identidade, dos estranhamentos, os processos de desintegracao e de resistencia dos/nos faxinais etc. Atraves da utilizacao da fonte oral, das falas dos moradores pesquisados, vai reconstruindo, pelas suas narrativas, as experiencias vividas, as mudancas, os medos e as ansiedades. Evidencia, via observacoes e entrevistas, conflitos latentes desencadeados pela desestruturacao do criadouro comum, cuja extincao resultaria na desarticulacao do sistema Faxinal, e analisou meticulosamente o drama vivido pela populacao de Marmeleiro de Baixo. A insercao da pesquisadora no cotidiano do faxinal resultou na elaboracao de documentos oficiais e de outras fontes construidas ao longo do tempo. Foram cinco anos de trabalho de campo, com conquistas significativas para a comunidade, pondo em debate questoes sobre os faxinais no Estado do Parana.
This paper aims to understand how the news in newspapers referring to the Workers’ Party (PT) in Ponta Grossa in the 1980s can be understood through Sentiment Analysis. In this sense, the journalistic publications of a certain spatial and temporal cut are analyzed, with the use of opinion mining techniques applying artificial intelligence to decipher aspects of natural language. We used the Syuzhet package included in Rbase, through the Rstudio interface, where we could verify that the positive emotions and feelings transmitted by the news published during the time under analysis, contributed to the electoral adhesion to the PT, electing members in the legislative and executive branches of the municipal government, a situation that had its share of influence in later decades in other spheres of the State. In this paper we try to make clear the path to reach our results, allowing the methodology to be applied to other printed periodicals and other themes.
This paper analyzes the regional integration process in South America and discusses the main difficulties and obstacles until 2016. During the 2000s, with the so-called Pink Tide, there was the rise of several left-wing and center-left governments in the region, which were dedicated to formalizing regional integration initiatives to project South America as a center of power on the international scene. However, these initiatives were not homogeneous in their ideological aspects, generating some contrasts between them. Also, with the decline of the left-wing and center-left governments in the region between 2011 and 2016, the initiatives gradually weakened, causing a setback to regional integration in the subcontinent.
This paper provides an overview of the main researches carried out on geodiversity and related themes in Brazil in journals CAPES classification A1, A2, B1, and B2. Based on the survey carried out between 2010 and 2016, there was an increase, albeit small in concerning the number of publishers works, since for the 2010-2012 three-year period 29 publications were identified and, for the quadrennium of 2013-2016 this number totaled 35 articles. For the 2010-2012 triennium, the region of the country that displayed primacy over publications related to geodiversity and other related concepts, was the Southeast Region of the country, followed by the Northeast and South regions. For the 2013-2016 quadrennium, there was a concentration of surveys in the Northeast, followed by the Southeast and South. The surveys address the relationship between geodiversity and geotourism, discussing the importance of recognizing geodiversity and using sustainable bases for geotourism in the different regions of the country.
Tornadoes are columns of air in very high rotation, which have high destructive power. The phenomenon happens in Brazil, but its occurrence is little recognized. In this work, we intend to characterize the multiple vortex tornado that occurred in Marechal Cândido Rondon and Quatro Pontes in 2015, to find out if there was the possibility of identifying the hook echo in the radar image. For that, the images made available by the Meteorology System of Paraná were compared with the course of the phenomenon. The analyzes performed allowed the glimpse of a hook in the area of occurrence, demonstrating that the event had a signature. However, the subscription took place very quickly, with only 7 minutes in advance.
The main goal of this paper is to identify the new patterns that tourism will assume due to demographic changes to be experienced by the Mexican and other societies during the next three decades. Through a Qualitative Approach, the main source of information was obtained by comparative assessments of academic and periodical data enriched by the conduction of personal interviews with decision-makers involved in Tourism both in Mexico and in the United States. The document points out that the main factors that will undoubtedly change the tourist activity are, in addition to the process of population aging, the conditions of inequality generated by the globalization model, and the effects of the COVID -19 pandemic. The results suggest that tourism will face the challenge of reinventing itself, turning towards the local-regional and toward the elder segment of the population leaving behind the massive ingredients that tourism prioritized during the rise of the globalization model.
Our objective is to understand the relationship between society and nature and the concept of sustainable development present in the UN's Agenda 2030 document, from a dialogue between the critical and decolonial perspectives. To this end, we divide this discussion into three moments: first, we address the relationship between society and nature, then, we analyze the concept of sustainable development, conducting a dialogue with the decolonial perspective and the Latin American territorial problematic. In the third moment we make considerations in view of the challenges to be faced to build sustainable development in Latin America: the possibility of producing knowledge from the bottom up; with and from the people and places; recognizing the pluriversity and multidimensionality of the society-labor-nature-humanity relations; thinking of diverse forms and possibilities of sustainable development.
The trauma that resulted from the construction of large hydroelectric dams in the Amazon is marked by major social and environmental restructuring, plunder, and impacts, on Indigenous Lands, Conservation Units, and residents on the outskirts of cities or through the country roads. In general, the effects caused by the Belo Monte HPP gain prominence and production, in which one of them composes the objective of this article: to analyze the impacts on the fishing territory. Having as methodological path the bibliographic review, field, and relative work with the fishermen of the Fishing Colony Z-57. It appears that the installation of the plant ended up deleteriously altering the systemic and cultural relations, under which the fishing territory is expressed. Compromising it, translating into low fishing stocks in the communities; a decrease of up to 70% in fisheries production and, consequently, an increase in pain and economic costs for carrying out the activity. It was evident that the legal frameworks and the licensing instruments, all the judicialization resulting from these infrastructure projects, and the struggle imposed on their installation, were not capable of safeguarding the interests of society - fishermen, specifically - in the face of the despoliation effect of the construction of the hydroelectric dam on the fishing territory.
No presente estudo, foram identificados quatro dominios morfoestruturais nominados por numeros romanos. O DM I (Dominio Morfoestrutural I) corresponde ao compartimento do relevo esculpido sobre as rochas basalticas da Formacao Serra Geral, e que apresentam nas suas partes mais escarpadas, arenitos das formacoes Botucatu e Piramboia. O DM II compreende os terrenos que abrangem os argilitos e os siltitos da Formacao Rio do Rasto, situados nas partes mais baixas do compartimento, e os arenitos da Formacao Botucatu, nas partes mais altas. O DM III apresenta relevos modelados sobre rochas areniticas da Formacao Botucatu e Piramboia. O DM IV corresponde ao compartimento mais rebaixado, onde predominam arenitos, siltitos e argilitos das formacoes Rio do Rasto e Teresina.
Pirai da Serra representa uma area prioritaria para a preservacao devido as suas caracteristicas peculiares e sua localizacao na Escarpa Devoniana, proximo ao cânion do Guartela. A regiao de 51.200 ha, com predominio de Florestas com Araucaria e campos de altitude associados pertence ao bioma Mata Atlântica, um dos mais ameacados do Brasil. Caracteristicas naturais e antropicas promoveram a fragmentacao desses habitats nativos. Com o intuito de subsidiar futuras inferencias sobre tais processos, esse artigo propoe-se a caracterizar a vegetacao local. Com base em dados ja existentes sobre o uso da terra, foram coletadas informacoes em campo referente a vegetacao florestal e campestre. Nas areas de campo seco e de afloramentos rochosos foram observados 83 taxons, distribuidos entre 33 familias; nas areas de campos umidos, 12 taxons em 7 familias; e nas areas de cerrado, 65 taxons pertencentes a 30 familias. Nas areas florestadas, observou-se 74 taxons em 29 familias. A analise reforca a necessidade de medidas mitigadoras que busquem frear a progressiva fragmentacao dos habitats em Pirai da Serra.
O acesso rapido as informacoes sobre diversidade botânica e ecologia, o planejamento de medidas de conservacao eficientes, a valorizacao e a manutencao dos servicos do ecossistema e a promocao de estilos de vida sustentaveis no neotropico sao hoje em dia assuntos extremamente urgentes e importantes. A identificacao correta das plantas e fundamental para todos esses processos e continua a ser um desafio para a maioria dos usuarios desse tipo de informacao, com grande parte da literatura taxonomica ainda relativamente inacessivel e dedicada a um publico extremamente especializado. Com a finalidade de tornar essa informacao disponivel para um maior numero de pessoas, a Neotropikey fornece ferramentas on-line para identificacao de plantas neotropicais, atualmente incluindo uma chave eletronica de acesso multiplo e resumos ilustrados das familias de angiospermas na regiao. Trata-se de um projeto colaborativo, liderado pelo Royal Botanic Gardens em Kew (Reino Unido), que envolve taxonomistas de toda a America Latina, bem como de outros paises do mundo. Entre os produtos futuros, estao previstas chaves a nivel generico e descricoes de genero interativas. O presente artigo descreve os resultados do projeto, incluindo as estrategias e os metodos utilizados para atingir esta fase, assim como os desafios enfrentados na preparacao deste tipo de recurso e as oportunidades para colaboracao e desenvolvimento que serao acarretadas a partir deste momento.
A forma de producao do conhecimento inovador social abrangeu, na ultima decada, nao apenas as areas urbanas, mas tambem o espaco rural, de onde se observa os impactos da juncao entre o saber produtivo ancestral e as bases de decodificacao coletivo-cientifica das tecnicas de producao ecologica. De igual modo, a agroecologia emerge como pratica de concretizacao da juncao entre o agricola tradicional e o conhecimento cientifico, tendo nas inovacoes sociais agricolas o seu icone de continuidade. Desta forma, a inovacao social agroecologica encontra na trama das redes produtivas regionais os elementos ideais de sua propagacao.
In Brazil, about 24% of the population declares to have some type of disability. In this context, the urban infrastructure of the cities must be prepared for the mobility of these people. Displacement made on foot is often faced by non-existent or impassable sidewalks, making it a risk for pedestrians. The objective of this research was to analyze the conditions of sidewalks located in the surroundings of the places Raposo Tavares, and Napoleão Moreira da Silva located in the ZCC in the city of Maringá, regarding accessibility and other normative criteria established by NBR 9050 (2015) and NRM U-20001 (2016). The methodological procedures included an on-site survey, in which the conditions of the sidewalks were observed and compared with the requirements established by the technical standards. The results demonstrated the existence of non-compliance in both analyzed areas.
A new configuration of the sugar-energy sector emerges in the current century, marked by a significant expansion inherent to the actions of the Government. Driven by this process, the Geographic Microregion (MRG) of Ituiutaba has, in the recent period, experienced a significant expansion of sugarcane production, confirmed by the insertion of four processing plants (three currently active). In this sense, the objective of this work is to evaluate the logic of the three sugar-energy plants located in the MRG of Ituiutaba, presenting their radius of action to understand the spaces activated by each of the units in the access to the raw material. This expansion of sugarcane cultivation occurred morely in areas destined for pastures (traditional for extensive cattle raising), resulting in the reconversion of these areas into sugarcane plantations in the recent period. We identified in the MRG the plants’ expansion of their theoretical radius of action to access the raw material due to the competition among the sugar-energy plants and other agribusiness agents. In this way, the sugar-energy plants activate very distant spaces to supply their crushing demand, reaching 94 km towards the Santa Vitória plant and 62 km towards the BP plant.
This paper aims to portray the situation of access to basic sanitation in Brazilian regional capitals as mid-sized cities. It also intends to demonstrate the prospects of access to basic sanitation through projections, considering the advance of demographic growth and the targets set by the Federal Government for a 20-year horizon. Data from the demographic censuses of 1991, 2000, and 2010 were used upon 64 regional capitals. The results show that access to basic sanitation has progressed in recent decades, although serious deficiencies persist, especially due to the country’s regional disparities. The projections highlight a scenario of expansion and, sometimes, the universalization of access, but indicate cases in which the situation should be unsettling, demanding imminent public policies and investments in infrastructure that meet the new local demand
The Acôgo stream watershed is located in the Miranda Depression. Thus, the basin is located in the transition between the Pantanal Plain and the Maracajú-Campo Grande Plateau, presenting social, cultural, and environmental dynamics typical of the region marked by the existence of large rural properties that carry out extensive livestock. The native vegetation suppression of Brazilian Cerrado for implantation of exotic pastures is facilitated by the flattened relief. This paper aims to analyze the dynamics of land use and coverage correlating it with the geomorphometric dynamics (Relief Energy) of this watershed. The Relief Energy map expresses a mathematical measurement of the relief, and originates from the synthesis between the Letters of Interfluvial Amplitude, Altimetric Amplitude and Declivity. Although the basin presents geomorphometric potential for morphodynamic stability, it is unbalanced when climatic, pedological, geological, and anthropic factors are analyzed, and geomorphometric stability proved to be a facilitator of anthropic occupation for the use of pastures. Its implementation led to a sharp deforestation, with only 24.82% of forest remnants left in the basin to 73.76% of pastures. The analysis and environmental planning of the basin should be based on the observance of the various elements involved, seeking to address anthropic and natural issues, aiming to contribute to its dynamic balance. Thus, it is indicated the need to adoption conservation practices of vegetation and improvement of existing pastures, which can meet the needs of economic activity without the continuity of the removal of forest remnants.
It is proposed to discuss territorial mobility, the policies of indigenous leaders in the state of Acre, especially the Manchineri, their survival strategies in the world of non-indigenous people so that we can reflect on two changes that we testify in recent decades: mobility for the urban centers that include the indigenous people who were born in the city and those who arrived in the city, as well as its growing support in the country’s indigenous and non-indigenous political discussions in Brazil. The methodological path had as its own perspective of the leaders, for this will be reported their way of life and their involvement in the policies of different spheres of decision. The paper consists of three discussion sections that go from mobility to the political role played by leaders.

With the emergence of a globalized world, in which decisions depend on information on the most varied geographic scales, from local to global, it is essential that the management of companies, whether public or private, be guided by a vision of totality. Based on this assumption, the hypothesis of this study was to demonstrate the absence of formalized Geography in the curriculum of Administration courses (in higher education). The methodological procedures were based on documental verification (by analyzing the curriculum of the main Administration courses in the country), in which data on the official training of managers and how the curriculum of these courses is constituted were analyzed. It was identified deficiency in the training process of these professionals, highlighting the lack of approaches regarding fundamental notions of Geography during the teaching stages. This condition shows that administrative science still does not formally recognize the collaborative potential of Geography, a key discipline in stimulating the spatial thinking of managers that contributes to the full understanding of contemporary reality.
This paper discusses the recent territorial reconfiguration in four cities of the Central Administrative Region of the state of São Paulo, through axes of analysis that mainly cover real estate dynamics and urban mobility. As from the cities of São Carlos, Ibaté, Araraquara, and Matão, a very specific territorial reconfiguration process is proposed in the medium and small cities of the state, as a result of a much more registered housing production in a context of financing which marks the production of the city itself, than in response to the more general picture of effective demands for housing in these cities, legitimized by local-scale urban legislation, and the misused use of urban tools recognized for the right to fairer cities.

Urban afforestation provides a series of social, environmental, and economic benefits. Due to its importance for the quality of urban life, knowledge of the arboreal heritage offers subsidies for the public authorities to develop and improve management plans for urban afforestation. The goal was to survey the spatial distribution and estimate the potential for planting trees on streets in the urban area of Ponta Grossa, a medium-sized city in southern Brazil. Through visual analysis with the support of high-resolution images from the Pleiades sensor, as well as fieldwork in some places, it was estimated the number of trees per kilometer of road. It was observed 28,925 trees and the potential for planting 64,122 trees. Thus, there is a deficit of 35,197 trees. As it was obtained 22.52 trees/km on average, it arises a ‘very high’ level of attention. So, these data provide subsidies for the development of an urban forestation plan that contemplates street forestation
The understanding of the relationships between abiotic components and these with the natural system, especially in coastal areas and densely occupied areas, such as urban agglomerations, has been important to support policies of conservation,
preservation, and sustainable regional development. In this sense, the aim of this study
was to carry out an assessment on a regional scale of the geodiversity of the Urban Agglomeration of the South (AUSul), the coast of Rio Grande do Sul, and its constituent municipalities, through a geodiversity index and the occurrence and distribution of its elements in the region. To construct the index, the abiotic elements considered most relevant for the region’s characteristics and the availability of data approximately compatible with the 1:250,000 scale was qualitatively defined. Subsequently, they were
treated with methods of map algebra, resulting in the maps of the sub-indices related to geology, topography and geomorphology, hydrography and soils per municipality, and the geodiversity index of each municipality and the region. The results indicate the municipalities located on the Sul-Rio-Grandense Plateau and at the interface with the Coastal Plain with the highest indexes, being influenced by the greatest diversity of geological units, relief types, altimetric variations, and hydrographic features. Despite the significant occurrence of large wetland areas in the Coastal Plain municipalities, their indices were the lowest. The study proved to be useful for the understanding
of the geodiversity of the AUSul, pointing out areas for studies at larger scales and macro-zoning, in addition to the need for complementation with methods that incorporate subjective characteristics of geodiversity.
The understanding of the countryside as a place of conflict and territorial disputes is an issue that has been constantly deconstructed by the popular media, which ends up being commonly proclaimed as the domain of the extensive production of agribusiness. However, in this study another perspective of the countryside is placed, a territory of life, of culture, of people, in addition to the coldness in the so-called ‘green deserts’, where public policies, although quite small, may also be sought and conducted to enable the peasant way of life. This research presents a brief diagnosis of the Brazilian countryside a reflection that is displaced from the dichotomous sense of the countryside since it is known that Brazil, a country with continental extensions, has full capacity to support capitalists, and peasant agriculture. Thus, a debate enshrined in the dialectical bias of these territories. Finally, the issue of peasant education is taken as a specificity, stressing the importance of this public policy to strengthen the resistance strategies of the peasant movements, since the structured peasant education is a tool to crystallize the identity of social mobilization and future generations formation.
This article presents a diagnosis of the opportunities for the development of
geotourism in the Sierras do Agreste Potiguar, raised through the evaluation of natural, historical, and cultural attractions, as well as equipment and services. Tourist planning needs to highlight the creative processes with a focus on brand management, a parameter for promotion, management, and dissemination of the localities. Therefore, the results allowed us to understand, in general, the categorical importance of the execution of policies for the expansion of the sector, with a priority focus on the effectiveness of geomarketing for decision making within new instruments, regionalization programs, and strengthening of the industry. Given this scenario, one can highlight that the landscape peculiarities present in the territory were determinant for the identification.
