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.

(RN), s?o representantes do magmatismo ediacarano a cambriano, uma fei??o magm?tica marcante da orog?nese Brasiliana / Panafricana na Prov?ncia Borborema. Estes corpos s?o an?logos litol?gicos, intrusivos no embasamento gn?issico paleoproterozoico, estando separados por uma t?nue faixa de ortognaisses milon?ticos. As rela??es de campo mostram uma estratigrafia magm?tica iniciada pela f?cies dior?tica que coexiste com as f?cies gran?tica porfir?tica e gran?tica equigranular I e, em menor frequ?ncia, com a f?cies gran?tica equigranular II. Estas rochas s?o cortadas por diques e sheets gran?ticos tardios NE-SW a NNE-SSW. A f?cies dior?tica (dioritos, quartzo dioritos, quartzo monzodioritos, tonalitos e granodioritos) ? leucocr?tica a melanocr?tica, rica em biotita e anfib?lio. As f?cies gran?ticas s?o hololeucocr?ticas a leucocr?ticas, com biotita ? anfib?lio. Dados petrogr?ficos e geoqu?micos (rocha total) provenientes em maior propor??o do plut?o Serra do Caramuru, sugerem o fracionamento de zirc?o, apatita, clinopirox?nio (em dioritos), opacos, titanita, biotita, hornblenda, allanita, plagiocl?sio, microcl?nio e granada (em diques). O comportamento dos elementos tra?os Zr, La e Yb indicam que dioritos n?o constituem o magma parental dos granitos. Por outro lado, as f?cies gran?ticas s?o cogen?ticas entre si, apresentando trends de diferencia??o e espectros de elementos terras raras (ETR) an?logos [12.3?(La/Yb)N?190.8; Eu/Eu*=0.37-0.68]. Rela??es de campo e padr?o de ETR [6.96?(La/Yb)N?277.8; Eu/Eu*=0.18-0.58] demonstram que os diques e sheets gran?ticos n?o s?o cogeneticamente relacionados ao magmatismo Serra do Caramuru. A f?cies dior?tica ? metaluminosa (A/CNK = 0.88-0.74), shoshon?tica, ao passo que granitos s?o metaluminosos a peraluminosos (A/CNK = 1.08-0.93), c?lcio-alcalinos de alto pot?ssio. Diques e sheets s?o estritamente peraluminosos (A/CNK = 1.01-1.04). Diagramas bilogar?tmicos relacionando elementos compat?veis e incompat?veis e microtexturas indicam a cristaliza??o fracionada como o mecanismo dominante na evolu??o magm?tica das diversas f?cies. Os stocks Serra do Caramuru e Tapuio mostram trama magm?tica bem preservada, aus?ncia de minerais metam?rficos e s?o estruturalmente isotr?picos, com rela??es de contato discordantes da trama d?ctil do embasamento gn?issico. Estas observa??es conduzem a um est?gio de relativa estabilidade tect?nica, compat?veis com o per?odo de relaxamento orogen?tico da cadeia Brasiliana / Panafricana. Os diagramas qu?micos discriminantes envolvendo ?xidos e elementos tra?os indicam um ambiente tardio ? p?s-colisional. Neste contexto, o mecanismo de coloca??o que melhor explica o alojamento dos stocks seria a abertura de espa?o em fraturas de Ridel tipo T, com vetor de estiramento orientado ENE-WSW. A idade U-Pb de 553 ? 10 Ma permite correlacionar o magmatismo Serra do Caramuru aos grupo de granitoides tardios a p?s-colisionais, c?lcio-alcalinos de alto pot?ssio equigranulares, do extremo NE do Dom?nio Rio Piranhas-Serid?. / The Serra do Caramuru and Tapuio stocks, located in the extreme NE of Rio Piranhas-Serid? Domain (RN), are representative of the Ediacaran-Cambrian magmatism, an important magmatic feature of the Brasilian / Panafrican orogeny of the Borborema Province. These bodies are lithologically similar, intrusive in paleoproterozoic gneiss embasement, being separated by a thin belt of mylonitic orthogneiss. The field relations show a magmatic stratigraphy initiated by dioritic facies that coexists with the porphyritic granitic and equigranular granitic I facies, and less frequently with equigranular granitic II facies. These rocks are crosscut by late granitic dykes and sheets with NE-SW / NNE-SSW orientation. The dioritic facies (diorite, quartz diorite, quartz monzodiorites, tonalite and granodiorite) is leucocratic to melanocratic, rich in biotite and hornblende. The granitic facies are hololeucocratic to leucocratic, and have biotite ? hornblende. Petrographic and geochemical (whole rock) data, especially from Serra do Caramuru pluton, suggest fractionation of zircon, apatite, clinopyroxene (in diorites), opaque minerals, titanite, biotite, hornblende, allanite, plagioclase, microcline and garnet (in dykes). The behavior of trace elements such as Zr, La and Yb indicates that the dioritic magma does not constitute the parental magma for the granitic facies. On the other hand, the granitic facies seems to be cogenetic to each other, displaying differentiation trends and very similar rare earth elements (REE) spectra [12.3?(La/Yb)N?190.8; Eu/Eu*=0.30-0.68]. Field relationships and REE patterns [6.96?(La/Yb)N?277.8; Eu/Eu*=0.18-0.58] demonstrate that the granitic dykes and sheets are not cogenetically related to the Serra do Caramuru magmatism. The dioritic facies is metaluminous (A/CNK = 0.88-0.74) and shoshonitic, whereas the granitic ones are metaluminous to peraluminous (A/CNK = 1.08-0.93) and high potassium calc-alkaline. Dykes and sheets are strictly peraluminous (A/CNK = 1.01-1.04). Binary diagrams relating compatible and incompatible trace elements and microtextures indicate the fractional crystallization as the dominant mechanism of magmatic evolution of the various facies. The Serra do Caramuru and Tapuio stocks have well preserved magmatic fabric, do not show metamorphic minerals and are structurally isotropic, showing crosscutting contact with the ductile fabric of the basement. These observations lead to interpretate a stage of relative tectonic stability, consistent with the orogenic relaxation period of the Brasiliano / Pan-African orogeny. Chemical plots involving oxides and trace elements indicate late to post-collisional emplacement. In this context, the assumed better mechanism to describe the stocks emplacement within an extensional T Riedel joint, with ENE-WSW extensional vector. The U-Pb zircon age of 553 ? 10 Ma allows correlating the Serra do Caramuru magmatism to the group of post-collisional bodies, equigranular high potassium calc-alkaline granites of the NE of Rio Piranhas-Serid? Domain.

Nessa perspectiva, esse estudo tem por objetivo investigar e conhecer o papel que os cons?rcios, em especial o Cons?rcio P?blico Regional de Res?duos S?lidos do Serid?/RN, t?m na gest?o dos res?duos, com o prop?sito de observar suas fortalezas e debilidades, com o intuito de concluir se estes s?o uma solu??o adequada para a problem?tica dos res?duos s?lidos. Ao estudarmos uma regi?o que est? passando por um processo de organiza??o institucional pautada nos res?duos s?lidos, o foco transformou-se em um ponto de investiga??o acad?mica interessante. Se tratando de uma pesquisa qualitativa, foram realizadas leituras de autores pertinentes ao objeto e dos seguintes marcos legais, a saber: a Pol?tica Nacional de Saneamento B?sico (Lei n? 11.445/2007), a Pol?tica Nacional de Res?duos S?lidos (Lei n? 12.305/2010) e a Lei de Cons?rcios P?blicos (Lei n? 11.107/2005). A regi?o consorciada possui cerca de 290.000 habitantes, sendo geradas 40.000 toneladas de res?duos ao ano. Quanto ? destina??o final dos res?duos, todos os munic?pios da regi?o depositam seus res?duos a c?u aberto, ou seja, em lix?es. Na an?lise sobre o Cons?rcio do Serid?, foi identificado um rol de quest?es que est?o dificultando a sua implementa??o. As demandas passam, principalmente, pela esfera pol?tica, mas tamb?m por aspectos financeiros, t?cnicos e log?sticos. Espera-se que, com a efetiva??o do Cons?rcio atrav?s da constru??o das suas estruturas de apoio (Esta??es de transbordo e Aterro Sanit?rio), um novo modelo de gest?o dos res?duos s?lidos seja implantado. / The problem of solid waste that involves the management, the management and the allocation of these is an issue that permeates all spheres of society, which denotes environmental implications that contribute to the discussion of the environmental crisis in progress. From this perspective, this study aims to investigate and understand the role that consortia, especially the Regional Public Waste Consortium Solid Serid?/RN have waste management, in order to observe their strengths and weaknesses in order to conclude whether they are an appropriate solution to the problem of solid waste. In studying a region that is undergoing a process of institutional organization guided in the solid waste, the focus turned into an interesting academic research point. Since this is a qualitative research, readings were taken of relevant authors to the object and the following legal frameworks, namely: the National Basic Sanitation Policy (Law n? 11.445/2007), the National Policy on Solid Waste (Law n? 12.305/2010 ) and the Law on Public Consortia (Law n? 11.107/2005). The consortium region has about 290.000 inhabitants, generated 40.000 tons of waste a year. As for the final disposal of waste, all municipalities in the region deposit their waste in the open, or in garbage dumps. In the analysis of the Consortium Serid?, a list of issues that are hindering their implementation has been identified. The demands come mainly from the political sphere, but also financial, technical and logistical. It is expected that with the realization of the Consortium by building its supporting structures (overfill Station and Landfill), a new model of solid waste management is implemented.

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.
