Assim, partese do pressuposto de que a leitura escrita ? fundamental para o processo de ensinoaprendizagem, al?m da relev?ncia de se levar em considera??o a viv?ncia do aluno. Cabe destacar que os livros paradid?ticos s?o materiais que praticamente n?o s?o utilizados pelos docentes de Geografia. Embora saibam da exist?ncia deles no contexto escolar e de suas possibilidades de uso, ainda n?o conseguem inseri-los no ambiente de sala de aula. Dessa maneira, foi elaborado um material a partir das dificuldades apresentadas pelos alunos do 6? ano do Ensino Fundamental e seus respectivos professores de Geografia. Produziu-se, assim, uma obra na qual a personagem Beli narra sua aventura com seus amigos L?o e Tajuba pela Regi?o do Serid? Potiguar. No percurso dessa jornada, os alunos leitores v?o descobrir aspectos econ?micos, culturais, sociais e hist?ricos da Regi?o do Serid?, que dar?o subs?dio para o professor trabalhar os conte?dos e conceitos da Geografia abordados no 6? ano do Ensino Fundamental. Levaram-se em considera??o os atrativos que agu?am os alunos na escolha de um livro, al?m de usar uma linguagem menos formal. Para o educador, preparou-se uma proposta metodol?gica a partir do enredo do livro, mas cabe ressaltar que n?o ? um receitu?rio, posto que a melhor estrat?gia ? aquela que conduz o aluno ao aprendizado, de modo que o professor ? quem conhece a realidade dos seus alunos. Por fim, esperamos que esse livro contribua para o processo de ensino-aprendizagem da Geografia, incentivando os docentes a utilizar esse recurso did?tico. / This paperwork intends to present the drafting and creation of the supplementary book O Castigo Veio a Cavalo, an educational material that allows Geography teachers to work on matters such as place and scenery throughout a local point of view. Therefore, the main assumption is that both reading and writing are fundamental to the teachinglearning process. It is also imperative that we take in consideration the student?s life experiences. It is worth highlighting that supplementary books are rarely used tools by Geography lecturers. Although they are aware of such existence and its capabilities in the scholar context, they are yet not certain of how to insert them inside classroom walls. Hence, because of the difficulties shown by both lecturers and students of the 6th grade Elementary School, this book. In this work, the main character Beli tells her adventure along with her friends, L?o and Tajuba, across the Serid? Potiguar region. In their journey, the readers are going to learn about the socio-economic and cultural aspects of the area. This will make easier for the teachers to work on Geography?s most important subjects and concepts with their 6th grade students. In the elaboration, it was also took in consideration what students consider the most appealing aspects of a book. The storyline presents a methodological proposal for teaching, but it?s necessary to highlight that such a proposal is not mandatory. The best strategy in apprenticeship is the one who leads the students towards learning, and the teacher, who knows his students better, is the one who should choose it. Finally, we hope that this book plays a role on the teaching-learning process and stimulate the lectures to use it as a didactic tool.

This study aimed to investigate the anthropogenic input of heavy metals in the environment, in the area of the Parelhas dump site and in part of the Serid? River and to determine the concentration of heavy metals in the sediments. This can result in risk to the environment and human health. In addition, we sought to establish the socioeconomic profile of rural communities adjacent to Serid? River and to comprehend the perception of these dwellers about the changes in the places they live. The area of this study is located in the city of Parelhas/RN, in the centralsouthern part of the State, in the micro-region of the Oriental Serid?. This area comprehends the place where the dump site is located, next to RN 086, the Caldeir?o dam, the Quintos river called by local citizens Caldeir?o creek and part of Serid? river, perpetuated by the Boqueir?o dam, which crosses the city and it includes the rural communities of Almas, Domingas, Sussuarana II and Colonos. Regarding the study with bottom sediments, the samples were collected and taken to the laboratory of geochemistry, where they were dried, sieved, weighted and submitted to weak acid attack. The analysis of heavy metals was held by Atomic Absorption Spectrophotometer - Flame AAS. We applied 23 closed questionnaires constituted by 38 questions to collect informations in the rural communities, oriented to establish the socioeconomic profile and the environmental perception of the participants. The participants were distributed in the communities of Almas (1), Domingas (2), Sussuarana II (10) and Colonos (10). Most of them presented similar socioeconomic profiles. They are from 45 to 60 years old and live in these localities for 20 to 30 years or more. The families are composed by 3 or 4 people; the agriculture is the main activity, livestock is the secondary and 48% of them earn the minimal wage. Regarding the environmental perception, the participants can realize some changes in vegetation, soil, water and landscape. People living longer in the community, and with more years of experience on the local reality can perceive the depletion of the soil, pastures and changes in the landscape. These changes portray how the place was previously and what it represents today. The perception of these changes, besides the environmental ones, includes others concerning the increasing number of dwellers in the last years, as well as the number of houses. The changes happened through activities developed by the dwellers over the years, including agricultural practices, livestock, grass planting and even the cultivation of cotton. The study provided the acquisition of new data about the environmental reality of this region. It can subsidize the definition of public policies that can be implemented from the perspective of conservation of water resources and of the coexistence and survival of man in the semi-arid / A conserva??o dos recursos naturais ? essencial e constitui o objeto principal de v?rias pesquisas, que caracterizam aspectos importantes concernentes ?s altera??es ambientais do solo, da ?gua, na paisagem e informa??es socioecon?micas. Este estudo objetivou investigar o aporte antropog?nico de metais pesados para o meio ambiente, na ?rea de influ?ncia do lix?o do munic?pio de Parelhas e em um trecho do Rio Serid?, visando determinar a concentra??o de metais pesados nos sedimentos, o que pode implicar em risco para o meio ambiente e a sa?de humana. Al?m disso, buscou-se conhecer o perfil socioecon?mico dos moradores de comunidades rurais adjacentes ao Rio Serid? e entender a percep??o destes moradores com rela??o a mudan?as nos espa?os onde vivem. A ?rea do estudo situa-se no munic?pio de Parelhas/RN localizado na Por??o Centro-sul do Estado, na Microrregi?o do Serid? Oriental. A ?rea da pesquisa abrangeu o local onde se encontra o lix?o do munic?pio, situado ao lado da RN 086, o A?ude Caldeir?o, o Rio Quintos denominado de Riacho Caldeir?o pelos moradores locais e um trecho do Rio Serid?, importante rio perenizado pela Barragem Boqueir?o, que corta o munic?pio e compreende ?s suas margens as comunidades rurais Almas, Domingas, Sussuarana II e Colonos. No que se refere ao estudo com sedimentos das drenagens, as amostras foram coletadas e levadas ao laborat?rio de geoqu?mica, onde foram secas, peneiradas, pesadas e submetidas a ataque ?cido fraco. A leitura dos metais pesados foi realizada por Espectrofot?metro de Absor??o At?mica AAS-CHAMA. Para coletar os dados das comunidades rurais foram aplicados 23 question?rios constitu?dos de 38 perguntas fixas, voltadas para o perfil socioecon?mico e percep??o ambiental dos participantes. Os participantes foram distribu?dos nas comunidades Almas (1), Domingas (2), Sussuarana II (10) e Colonos (10). A maioria dos entrevistados apresentou perfis socioecon?micos semelhantes, residem no local de 20 a 30 anos, est?o na faixa et?ria de 45 e 60 anos ou mais; as fam?lias s?o compostas de 3 a 4 pessoas, sendo a agricultura a atividade principal e a pecu?ria a secundaria; 48% dos entrevistados ganham um sal?rio m?nimo. Com rela??o ? percep??o ambiental dos entrevistados, estes conseguem perceber algumas mudan?as ocorridas na vegeta??o, solo, ?gua, na paisagem. As pessoas com maior tempo de moradia na comunidade e com mais anos de viv?ncia da realidade local podem perceber o desgaste do solo, das pastagens, e as mudan?as na paisagem que retratam como o local era anteriormente e o que hoje ele representa. A percep??o acerca das mudan?as, al?m das ambientais, inclui outras concernentes ao aumento do n?mero de moradores e de resid?ncias. Essas mudan?as ocorreram atrav?s de atividades desenvolvidas pelos residentes ao longo dos anos, as quais incluem pr?ticas de agricultura, pecu?ria, plantio de capim e at? mesmo a cotonicultura. O estudo propiciou a aquisi??o de novos dados sobre a realidade ambiental da regi?o, os quais podem servir de subs?dio ? defini??o de pol?ticas p?blicas a serem implementadas sob a ?tica da conserva??o dos recursos h?dricos, da conviv?ncia e sobreviv?ncia do homem no semi?rido

The historiographical discourse will be investigated as to representations of space and the frames of reference that demarcate it. We highlight the space of 1 as delimited by the subjectivity and significances expressed by each author, considering closely the relation between author, writing and body, either in historiography or in the subjects that give shape to the Serid? region in their writings. The Serid? is particularly framed in the relevant historiography as the hinterland (sert?o) space, where the drought is a representation referred to recurrently, and as a space of fight , in which man and nature would be in constant struggle, challenging each other. Spatial frames of reference are then situated between the 1 and notions of hinterland and fight with nature / O objetivo deste trabalho ? analisar as configura??es espaciais do Serid? potiguar situado na por??o centro-meridional do Estado do Rio Grande do Norte a partir das seguintes obras: Homens de Outrora (1941), de Manuel Dantas; Serid?

J? os objetivos espec?ficos foram: a) caracterizar as ?Inst?ncias de Governan?a? do turismo na regi?o do Serid?; b) levantar o perfil dos diferentes atores que comp?em as arenas p?blicas que discutem o turismo; c) investigar os mecanismos de participa??o dos atores nos processos decis?rios e seus pap?is na cadeia produtiva do turismo; d) levantar as principais a??es j? efetivadas no polo relacionado ao processo de desenvolvimento regional. Os procedimentos metodol?gicos utilizados foram a pesquisa bibliogr?fica, bem como documental, tendo car?ter explorat?rio/descritivo. A pesquisa adotou a abordagem qualitativa empregando como instrumentos de coleta de dados entrevistas semiestruturadas. Para tratar os dados foi adotada a t?cnica de an?lise de conte?do, al?m disso, foi realizado um registro fotogr?fico com vistas a levantar imagens que possam contribuir com a pesquisa. Com isso foi poss?vel concluir que a constitui??o da inst?ncia de governan?a em turismo, vem possibilitando novas discuss?es acerca da gest?o e planejamento do turismo na regi?o Serid? Potiguar. Observou-se ainda que existem dificuldades que comprometem o incremento do turismo na regi?o, bem como que as a??es desenvolvidas pela inst?ncia de governan?a do Polo Serid? ainda s?o pontuais, fator este que interfere na din?mica socioespacial e no pr?prio desenvolvimento tur?stico da regi?o. / The main objective of this study was to analyze the main actions taken and difficulties encountered by public arenas in the planning process and tourist hub management Serid? / RN. Already the specific objectives were: a) characterize the "Instances of governance" of tourism in the Serid? region; b) raise the profile of the different actors in the public arenas discussing tourism; c) investigate the mechanisms of stakeholder participation in decision-making processes and their roles in the productive chain of tourism; d) identify the main actions already effective on the pole related to the regional development process. The methodological procedures used were literature and documentary, with exploratory / descriptive. The research adopts a qualitative approach using as data collection instruments semi-structured interviews. To address the data has adopted the content analysis technique, furthermore, it was made a photographic record in order to get images that can contribute to the research. It was concluded that the establishment of the governance body in tourism, It is making possible new discussions of management and tourism planning in the Potiguar Serid? region. It was also observed that there are difficulties that compromise the growth of tourism in the region, and that the actions taken by the governance body of the Polo Serid? are still off, a factor that interferes with the socio-spatial dynamics and own tourism development in the region.

Potiguar. Esta ?ltima abriga, aproximadamente, metade das unidades produtivas do estado, onde se destaca o ramo de artefatos dom?sticos. A atividade concentra-se, outrossim, no interior da pr?pria regi?o, sobretudo em sua por??o ocidental, nos munic?pios de Caic?, Currais Novos e Jardim de Piranhas, cuja estrutura produtiva baseia-se em tecnologias obsoletas, em rela??o aos processos produtivos baseados em um elevado grau de capitaliza??o, com a origem local ou regional do capital e uso intensivo de m?o de obra barata e pouco qualificada. Diante do exposto, o presente trabalho tem como questionamento central: como uma atividade com as caracter?sticas da produ??o de artefatos t?xteis no Serid? Potiguar consegue lograr inser??o na din?mica atual dos circuitos espaciais produtivos e coexistir com os sistemas t?cnicos de ordem planet?ria? Desse modo, busca-se analisar o uso do territ?rio pelo circuito espacial produtivo t?xtil, com ?nfase na produ??o de artefatos dom?sticos a partir dos processos, din?mica e conte?do desta na regi?o do Serid? Potiguar. Para o desenvolvimento da pesquisa, realizou-se revis?o bibliogr?fica, sobretudo a partir de Andrade (1981), Arroyo (2008), Azevedo (2007, 2013), Barrios (2014), Castillo e Frederico (2010), Furtado (1969), Marx (1990, 2011), Moraes (1984), Santos (2012) e Silveira (2010b). Ademais, adotaram-se procedimentos te?rico-metodol?gicos de coleta e sistematiza??o de dados, baseados nas t?cnicas de pesquisa documental, pesquisa de campo ? na qual executou-se a aplica??o de entrevistas com base em roteiros semiestruturados e formul?rios ? articulada com uma base estat?stica. Constatou-se, atrav?s da pesquisa, que, tratando-se do circuito espacial da produ??o de artefatos t?xteis no Serid? Potiguar, os fluxos de mat?ria-prima s?o oriundos principalmente da pr?pria regi?o Nordeste, materializando a exist?ncia de monop?lio no fornecimento desses bens, controlado por empresas do Cear? com filiais no Rio Grande do Norte. Os fluxos do consumo produtivo de m?quinas e equipamentos s?o oriundos exclusivamente da regi?o concentrada, notadamente de S?o Paulo. Por outro lado, o consumo consuntivo ? marcadamente pulverizado, abrangendo sobretudo o Nordeste, e, com menor express?o, as regi?es Norte e Sudeste. Foi poss?vel depreender, outrossim, que o processo de circula??o ? completamente alienado, haja vista que as firmas locais det?m uma capacidade relativa de produ??o, todavia, por ocuparem posi??es subalternas no territ?rio, n?o det?m poder de mercado suficiente para realizar o seu controle, outorgando-lhe a a??o de atravessadores. Nessa esfera, a uni?o vertical dos lugares se sobrep?e em grande medida aos nexos horizontais coadunados ao uso produtivo do territ?rio do Serid? Potiguar. Considera-se que a baixa coes?o social e produtiva entre os agentes do ramo t?xtil verificada no referido recorte se d? pela aus?ncia, em certa medida proposital, do Estado, enquanto promotor de pol?ticas p?blicas, e em detrimento do desenvolvimento da pr?pria atividade na regi?o. As acanhadas iniciativas do Poder P?blico insistem em pensar os ramos produtivos isoladamente, e n?o o territ?rio usado como um todo, isso quando n?o legam, arbitrariamente, o seu papel aos interesses corporativos. / The production of textile artifacts is spatially distributed in the state of Rio Grande do Norte in a way that it is concentrated in the metropolitan area of Natal and in the Serid? Potiguar region. The later houses 49% of the total of production units of the State, with emphasis on the domestic utensils field (FIERN, 2017). The activity is likewise concentrated within the region itself, especially in its western half, in the municipalities of Caic?, Currais Novos and Jardim de Piranhas. Their productive structure is based on obsolete techniques and technologies, with the origin of the capital being local or regional and intensive use of cheap and low-skilled labour. In view of the above, the present study has as central question: how can an activity with the characteristics of the production of textile artefacts in Serid? Potiguar be successfully inserted in the current dynamics of spatial circuits of production and, moreover, coexist with the hegemonic technical systems of planetary order? Therefore, the aim is to analyze the use of the territory by the spatial circuit of textile production, with emphasis on the production of domestic utensils, through its processes, dynamics and content in the region of the Serid? Potiguar. For the development of the research, a bibliographical review was carried out, mainly from Andrade (1981), Arroyo (2008), Azevedo (2007, 2013), Barrios (2014), Castillo and Frederico (2010), Furtado (1969), Marx (1990, 2011), Moraes (1984), Santos (2012) and Silveira (2010b). Furthermore, some theoretical and methodological procedures were adopted to collect and systematize data, based on the techniques of documentary research, field research - in which interviews were executed based on semi-structured scripts and forms - articulated with a spatial descriptive statistical baseline. It was determined, through the research, that in the spatial of production of textile artefacts in Serid? Potiguar, the raw material flow derives mainly from the Northeast region itself, materializing the existence of a monopoly, in these assets supply, controlled by companies from Cear? with subsidiaries in Rio Grande do Norte. The machine's productive consumption flow and equipment comes exclusively from the Concentrated Region, notably from S?o Paulo. Conversely, the consumptive consumption is markedly sprayed, embracing mainly the Northeast and, in a lesser extent, the North and Southeast region. It was possible to conclude that the circulation process is completely alienated, considering that local companies have a relative capacity of production, however, as they occupy subaltern positions in the territory, they do not own market power to hold their control, awarding themselves the middlemen action. In this field, the places vertical union overlaps to a great extent to the horizontal links with the productive use of the Serid? Potiguar territory. Considering that the low social and productive cohesion between the textile field agents verified in the mentioned cut by means of the absent, to a certain extent, of the State, as a public policies promoter, and in detriment of the development of the activity itself in the region. The shy initiatives of the Public Power insists on thinking about the productive branches in isolation, and not the territory used as a whole, when they do not arbitrarily transfer their role to the corporative interests.

O uso inadequado do solo pode levar a uma condi??o de degrada??o avan?ada, a qual ? denominada de processo de desertifica??o. No Brasil, existem v?rios N?cleos de Desertifica??o, dentre os quais o N?cleo de Desertifica??o do Serid? (RN-PB). Assim, o presente trabalho partiu da premissa de que o processo de desertifica??o na regi?o do Serid? Potiguar (RN), possivelmente, tem causado variabilidades na temperatura da superf?cie, no albedo e nos fluxos de energia e massa (evapotranspira??o/fra??o evaporativa). Para comprovar as mudan?as decorrentes deste processo foi realizada uma an?lise descritiva/comparativa entre dados de ?rea degradada e ?rea com Caatinga preservada (Esta??o Ecol?gica do Serid?-ESEC). Para tanto, utilizou-se de um algoritmo h?brido, o qual ? composto de parametriza??es de v?rios algoritmos tais como: o Surface Energy Balance Algorithms for Land/SEBAL, Simplified Surface Energy Balance/SSEB, Simplified Energy Balance Index/S-SEBI, e de imagens TM ? Landsat 5, das ?rbitas-ponto: 215/65, adquiridas gratuitamente junto ao INPE ? Instituto Nacional de Pesquisas Espaciais ? sob a condi??o de c?u claro, para datas dos anos de 1990, 1995, 1998, 1999, 2001, 2003, 2005, 2007. Comparando os resultados obtidos em ?rea degradada e vegetada, foi observado a exist?ncia de diferen?as entre os valores m?dios do albedo, saldo de radia??o e fra??o evaporativa. Esta diferen?a tamb?m foi comprovada de forma significativa por meio de teste estat?stico (teste t de student), o que corrobora a hip?tese de que o processo de desertifica??o derivado do mau uso do solo e das condi??es clim?ticas da regi?o est? causando altera??es nas vari?veis constituintes do balan?o de energia. / The change in soil cover causes changes in the energy balance and surface water balance. Inadequate soil use can lead to an advanced degradation condition, which is called a desertification process. In Brazil, there are several Desertification Nuclei, among which the Serid? Desertification Nucleus (RN-PB). Thus, the present work started from the premise that the desertification process in the Serid? Potiguar (RN) region has possibly caused variability in surface temperature, albedo, and energy and mass fluxes (evapotranspiration / evaporative fraction). To verify the changes resulting from this process, a descriptive / comparative analysis was carried out between degraded area data and preserved Caatinga area (Serid?-ESEC Ecological Station). For this, a hybrid algorithm was used, which is composed of parametrizations of several algorithms such as: Surface Energy Balance Algorithms for Land / SEBAL, Simplified Surface Energy Balance / SSEB, and S-SEBI, and Of images - Landsat 5, of orbits-point: 215/65, acquired free of charge from INPE - National Space Research Institute - under the condition of clear sky, for dates of 1990, 1995, 1998, 1999, 2001, 2003, 2005, 2007. Comparing the results obtained in degraded and vegetated areas, it was observed the existence of differences between the average values of albedo, radiation balance and evaporative fraction. This difference was also significantly demonstrated by means of a statistical test (student's t test), which corroborates the hypothesis that the desertification process derived from the misuse of the soil and the climatic conditions of the region is causing changes in the constituent variables of the Energy balance.

Essas mudan?as ocorrem por meio do trabalho do homem, que utiliza os recursos naturais, em prol do seu desenvolvimento. Por essa raz?o, a sociedade, tem a capacidade construir e reconstruir os lugares onde vive, deixando registradas na paisagem as transforma??es ocorridas. A paisagem ? modificada ao longo dos anos, e o homem ? fundamental para esse processo, pois al?m de ser o autor das mudan?as, consegue descrev?-las atrav?s da percep??o que tem de um mesmo lugar, seja referente ao passado ou ao presente. O objetivo geral dessa pesquisa foi compreender a percep??o dos moradores do munic?pio de Parelhas/RN em rela??o ? desertifica??o e ? mudan?a na paisagem. A pesquisa foi realizada na ?rea urbana e em tr?s comunidades rurais ? Juazeiro, Cachoeira e Cobra. Foram aplicados 26 formul?rios com os empres?rios, gerentes e/ou respons?veis pelas cer?micas e 176 com parte da popula??o urbana (102) e nas comunidades rurais, Juazeiro, Cachoeira e Cobra (74). Os m?todos estat?sticos utilizados para a an?lise dos dados foram Qui-quadrado de Person (??), o teste de Fisher e a An?lise de Correspond?ncia. Para a descri??o dos dados sociais dos respondentes, elaboraram-se tabelas de conting?ncia e quadros. Os resultados mostraram que a ind?stria de cer?mica existe no munic?pio desde meados da d?cada de 1980. Os produtos fabricados pelas ind?strias s?o telhas, tijolos, lajotas, casquilhos, blocos e manilhas, sendo a telha o artefato mais produzido. A principal fonte energ?tica utilizada pelas cer?micas ? a lenha, e 73% ainda fazem uso exclusivamente da lenha. A retirada sem t?cnica da vegeta??o deixa ?reas desnudas e solos expostos a eros?o, contribuindo para aumentar a susceptibilidade ao fen?meno da desertifica??o no munic?pio. A an?lise comparativa da percep??o dos moradores da zona rural e urbana sobre desertifica??o mostrou que a maioria dos respondentes j? ouviu falar a respeito do tema; no entanto, as pessoas que residem na cidade (79,41%) ouviram falar mais do que as que moram na zona rural (52,70%). Dentre as alternativas sobre os causadores do processo de desertifica??o no munic?pio, a atividade ceramista foi a mais indicada. Acredita-se que essa escolha esteja relacionada com o alto consumo dos recursos naturais locais (lenha, argila e ?gua) que a atividade demanda na fabrica??o de seus produtos. Os resultados da percep??o sobre mudan?a na paisagem dos moradores das comunidades rurais Juazeiro, Cachoeira e Cobra, mostraram que a maioria percebe mudan?a da paisagem local. Do mesmo modo, mudan?as na vegeta??o, no solo e nas pastagens foram relatadas. Aqueles na faixa et?ria de 25 a 59 anos foram os que mais perceberam mudan?as na paisagem. Os respondestes que estudaram at? o Ensino Fundamental foram os que menos perceberam a mudan?a na paisagem, enquanto aqueles com ensino m?dio completo/incompleto e ensino superior completo/incompleto foram os que mais perceberam mudan?as na paisagem. Esses resultados podem servir de subs?dio ? defini??o de pol?ticas p?blicas a serem implementadas no semi?rido do Estado do Rio Grande do Norte, sob a ?tica da conserva??o dos recursos naturais, em uma ?rea suscet?vel ao fen?meno da desertifica??o. Sugest?es de a??es s?o apresentadas. / The interrelation society/nature causes changes to the environment. These changes occur through the work of man, which uses natural resources, to support his development. For that reason, the society has the ability to build and rebuild the places where lives, leaving registered on the landscape the changes occurred. The landscape is modified over the years, and the man is critical to this process because, in addition to being the author of the alterations can describe them through the perception from a same place, either from the past or from the present. The general objective of this research was to understand the perception of the residents of the city of Parelhas/RN in relation to desertification and to the change in the landscape. The survey was conducted in the urban area and in three rural communities-Juazeiro, Cachoeira and Cobra. Twenty-six forms were applied with the entrepreneurs, managers and/or responsible for ceramics and 176 with part of the urban population (102) and in rural communities Juazeiro, Cachoeira and Cobra (74). Statistical methods used for data analysis were Person Chi-square (??), the Fisher test and correlation analysis. To describe the social data of the respondents, contingency tables and data frames were prepared. The results showed that the ceramic industry exists in the city since the mid-1980. The products manufactured by the industries are roofing tiles, bricks, tiles, bushings, blocks and shackles, being tile the most produced artifact. The main energy source used for ceramics is the firewood, and 73% still make exclusively use of wood. The withdrawal of vegetation without any technique leaves bare areas and exposed soils to erosion, contributing to increase the susceptibility to the phenomenon of desertification in the municipality. The comparative analysis of the perception of the residents of the rural and urban area on desertification, showed that most respondents have heard on the subject; however, the people living in the city (79,41%) have heard more than those who live in the rural area (52,70%). Among the alternatives on the causes of desertification in the municipality, the ceramic industry was the most indicated activity. It is believed that this choice is related to the high consumption of the local natural resources (wood, clay and water) that this activity demands in manufacturing their products. The results of the perception of change in the landscape of the inhabitants of the rural communities Juazeiro, Cachoeira and Cobra, showed that most of them noticed changes in the local landscape. Likewise, changes in vegetation, soil and grassland have been reported. Those aged 25 to 59 years were the ones who most noticed changes in the landscape. The ones who studied until elementary school were the ones that least realized the modifications in landscape, while those with complete/incomplete secondary education and complete/incomplete higher education were the ones that most noticed changes in the landscape. These results can serve as a subsidy to the definition of public policies to be implemented in semi-arid of Rio Grande do Norte State, from the perspective of conservation of natural resources, in an area susceptible to the phenomenon of desertification. Suggestions of actions are presented.

In the last years this territory has gone through a process of appropriation that has been substantially changing the environmental and social dynamism of the place. However, the industry of red ware has been focusing in some areas, mainly, in the county of Parelhas and Carna?ba dos Dantas. From this point of view, the aim of this work consists in analyze the use of these areas by the red ware industry and the transformations occurred with the expansion of the number of industries and the productivity raise, that requires bigger amounts of earthenware and wood, resources that are low in referred territory. As the result of this process, the suitable alternative has been to acquire inputs in other Rio Grande do Norte counties, as well as in Para?ba counties. To reach the proposed objective, the methodology of this work was consisted of bibliographic and empirical research, regarding the occupation that this activity covers in the Serid? region. From the information obtained during the research, it can be stated that the inputs to the production execution in the red ware industry are acquired in the geographic nearby lands. The analysis of the stages of the production(acquisition of raw material, production and commercialization) showed that the activity acts in a continuous area, having as principal consumer market other northeastern states and the state of Par?. The present study revealed that the pottery activity is set as untenable, because of non-stopping use of the argil and wood, resources that are vanishing from the area, which consume causes a many problems such as deforestation and erosion. Besides, the sale of productive lands for the red ware industries makes harder its good use by the familiar agriculturists in the development of agriculture and cattle raising activity, which for many times is the main economic activity of the place. The precariousness reveals in the constant accidents at work, that most of them are neglected by the local authorities, without any penalty to the industries. Therefore, the industry of red ware in Serid? uses the territory as a resource, leaving its environmental problems that my compromise the quality of life of the actual and future generations / Esta pesquisa tem como universo emp?rico, o territ?rio produtor de cer?mica vermelha no Serid? potiguar. Nos ?ltimos anos esse territ?rio passou por um processo de apropria??o que tem alterado substancialmente a din?mica social e ambiental do lugar. No Serid?, a ind?stria de cer?mica vermelha tem se concentrado em algumas ?reas, sobretudo, nos munic?pios de Parelhas e Carna?ba dos Dantas. Nesta perspectiva, o objetivo desse trabalho consiste em analisar o uso do territ?rio pela ind?stria de cer?mica vermelha e as transforma??es ocorridas com a expans?o no n?mero de ind?strias e no aumento da produtividade, o que requer maiores quantidades de argila e de lenha, recursos escassos no referido territ?rio. Em decorr?ncia desse processo, a alternativa encontrada tem sido adquirir os insumos em outros munic?pios do Rio Grande do Norte, como tamb?m em munic?pios paraibanos. Para alcan?ar o objetivo proposto, o encaminhamento metodol?gico envolveu pesquisa bibliogr?fica e emp?rica, considerando a espacializa??o que essa atividade abrange no territ?rio seridoense. A partir das informa??es obtidas durante a pesquisa pode-se afirmar que os insumos para a realiza??o da produ??o na ind?stria de cer?mica vermelha s?o adquiridos no seu entorno geogr?fico. A an?lise das etapas do circuito de produ??o (aquisi??o da mat?ria-prima, produ??o e comercializa??o) mostrou que esta atividade atua numa ?rea cont?nua, tendo como principal mercado consumidor os demais estados do Nordeste e o estado do Par?. O presente estudo revelou ainda que a atividade ceramista configura-se como insustent?vel, haja vista a recorr?ncia permanente ? argila e ? lenha, insumos escassos no territ?rio, cuja aquisi??o provoca uma s?rie de problemas como o desmatamento e a eros?o. Al?m disso, a venda dos solos f?rteis para as cer?micas dificulta o seu aproveitamento pelos agricultores familiares, no desenvolvimento das atividades agropecu?rias, que muitas vezes configura-se na principal atividade econ?mica da propriedade. A precariedade da atividade se revela nos constantes acidentes de trabalho, que na grande maioria, s?o negligenciados pelas autoridades locais, sem aplica??o de nenhuma penalidade ?s empresas. Assim, a ind?stria de cer?mica vermelha no Serid? usa o territ?rio de forma seletiva e excludente, deixando s?rias problem?ticas ambientais, as quais podem comprometer a qualidade de vida das atuais e futuras gera??es
