Considerando ainda particularidades locais e regionais, criando assim uma base cient?fica de apoio para a??es futuras no manejo da demanda h?drica no Estado. Foramutilizados dados de precipita??o mensal de 45 anos, compreendidos entre 1963 e 2007, dados cedidos pela EMPARN. A metodologia aplicada para se atingir os resultados foi composta inicialmente da an?lise estat?stica descritiva dos dados hist?ricos, para comprovar a estabilidadeda s?rie, posteriormente, foi aplicada a geoestat?stica como ferramenta base para a plotagem dos mapas das vari?veis, dentro da geoestat?stica optou-se pelo m?todo de interpola??o porKrigagem pois foi o m?todo que apresentou os melhores resultados e menores erros de plotagem. Dentre os resultados, destaca-se o ciclo anual da precipita??o do Estado que ? influenciado por mecanismos meteorol?gicos das diferentes escalas espaciais e temporais, onde os principais mecanismos moduladores desse ciclo s?o a Zona de Converg?ncia Intertropical (ZCIT) atuando de meados de fevereiro a meados de maio em todo o Estado, Ondas de Leste (OL), Linhas de Instabilidade (LI), Sistemas de Brisas e Chuvas Orogr?ficas atuando principalmente na faixa Litor?nea entre fevereiro e julho. Juntamente com V?rtices Cicl?nicos de Altos N?veis (VCANs), Complexos Convectivos de Mesoescala (CCMs) e chuvas orogr?ficas em qualquer regi?o do Estado principalmente na primavera e ver?o. Em termos de fen?menos de maior escala destacaram-se EL NI?O e LA NI?A, ENOS na bacia do Pac?fico Tropical, em epis?dios de LA NI?A, geralmente ocorrem anos normais a chuvosos, j? quando da ocorr?ncia de per?odos prolongados de escassez de chuvas s?o pela influ?ncia de EL NI?O. Na bacia do oceano Atl?ntico o padr?o de Dipolo tamb?m interfere na intensidade do ciclo das chuvas. O ciclo das chuvas no Rio Grande do Norte ? dividido em dois per?odos, um compreendendo as mesorregi?es Oeste, Central e Por??o Oeste da Agreste Potiguar a oeste da Chapada da Borborema, provocando chuvas de meados de fevereiro a meados de maio e um segundo per?odo de ocorr?ncia de chuvas, compreendido entre fevereiro a julho, onde as chuvas ocorrem na mesorregi?o Leste e restante da Agreste, situada a barlavento da Chapada da Borborema, ambos intercalados por per?odos secos sem ocorr?ncia de precipita??es significativas e por per?odos de transi??o de chuvoso-seco e de seco-chuvoso, onde podem ocorrem precipita??es isoladas. Aproximadamente 82% das esta??es pluviom?tricas do Estado o que corresponde a 83,4% da ?rea total do Rio Grande do Norte, n?o registram volumes anuais acima de 900 mm. Devido a oferta h?drica do Estado ser mantida por pequenos reservat?rios, que j? encontram - se em estado de eutrofiza??o avan?ado, quando ocorrem as chuvas, atuam para lavar e substituir as ?guas dos reservat?rios, melhorando a qualidade dessas, diminuindo o processo de eutrofiza??o. Pois quando as mesmas n?o ocorrem significativamente ou longos per?odos de escassez, o processo de deteriora??o das ?guas e eutrofiza??o dos a?udes aumenta significativamente. Atrav?s do conhecimento do comportamento anual do ciclo das chuvas se pode ter uma no??o pr?via de como poder? ser a tend?ncia do per?odo seguinte, tanto chuvosoou propenso a escassez, principalmente observando as tend?ncias dos fen?menos de maior escala. / This study aimed to evaluate the influence of the main meteorological mechanisms trainers and inhibitors of precipitation, and the interactions between different scales of operation, the spatial and temporal variability of the annual cycle of precipitation in the Rio Grande do Norte. Al?m disso, considerando as circunst?ncias locais e regionais, criando assim uma base cient?fica para apoiar a??es futuras na gest?o da demanda de ?gua no Estado. Database from monthly precipitation of 45 years, ranging between 1963 and 2007, data provided by EMPARN. The methodology used to achieve the results was initially composed of descriptive statistical analysis of historical data to prove the stability of the series, were applied after, geostatistics tool for plotting maps of the variables, within the geostatistical we opted for by Kriging interpolation method because it was the method that showed the best results and minor errors. Among the results, we highlight the annual cycle of rainfall the State which is influenced by meteorological mechanisms of different spatial and temporal scales, where the main mechanisms cycle modulators are the Conference Intertropical Zone (ITCZ) acting since midFebruary to mid May throughout the state, waves Leste (OL), Lines of instability (LI), breeze systems and orographic rainfall acting mainly in the Coastal strip between February and July. Along with vortice of high levels (VCANs), Complex Mesoscale Convective (CCMs) and orographic rain in any region of the state mainly in spring and summer. In terms of larger scale phenomena stood out El Ni?o and La Ni?a, ENSO in the tropical Pacific basin. In La Ni?a episodes usually occur normal or rainy years, as upon the occurrence of prolonged periods of drought are influenced by EL NI?O. In the Atlantic Ocean the standard Dipole also affects the intensity of the rainfall cycle in State. The cycle of rains in Rio Grande do Norte is divided into two periods, one comprising the regions West, Central and the Western Portion of the Wasteland Potiguar mesoregions of west Chapada Borborema, causing rains from midFebruary to mid-May and a second period of cycle, between February-July, where rains occur in mesoregions East and of the Wasteland, located upwind of the Chapada Borborema, both interspersed with dry periods without occurrence of significant rainfall and transition periods of rainy - dry and dry-rainy where isolated rainfall occur. Approximately 82% of the rainfall stations of the state which corresponds to 83.4% of the total area of Rio Grande do Norte, do not record annual volumes above 900 mm. Because the water supply of the State be maintained by small reservoirs already are in an advanced state of eutrophication, when the rains occur, act to wash and replace the water in the reservoirs, improving the quality of these, reducing the eutrophication process. When rain they do not significantly occur or after long periods of shortages, the process of eutrophication and deterioration of water in dams increased significantly. Through knowledge of the behavior of the annual cycle of rainfall can have an intimate knowledge of how it may be the tendency of rainy or prone to shortages following period, mainly observing the trends of larger scale phenomena

The goal of this study was to describe the temporal variation of benthic macroinvertebrates in an intermittent stream in the Brazilian semiarid region. From March to July of 2009, surveys of benthic macroinvertebrates and water physiochemical parameters were done in a first order stream located at Piranhas-A?u River basin. 25 macroinvertebrates families were found, 21 belonging to Insecta class. The chironomids were the most abundant group during all study period and were represented by 19 genus. The largest densities and taxonomic richness were seen in the drying phase of the stream while the smallest values were found in the period with the heaviest rainfalls ( wet phase ). Only the families Chironomidae and Ceratopogonidae were found during all study period, suggesting that these groups have better adaptations to support floods and droughts. Furthermore, these two groups seemed to be pioneering in this stream. Among the chironomids, Paratendipes dominated the period of floods while Tanytarsus were more abundant in the drying phase . This study showed that hydrological fluctuation is the main force influencing the macroinvertebrate community in this stream, therefore, efforts seeking the conservation and management of Brazilian semiarid water bodies should consider this high natural variability in flow regime / O semi?rido brasileiro possui grande parte de seus corpos de ?gua com car?ter tempor?rio e pouco se conhece sobre a biodiversidade destes ambientes e os fatores que influenciam esta diversidade. O presente estudo teve como objetivo caracterizar a varia??o temporal dos macroinvertebrados bent?nicos de um riacho intermitente da regi?o do semi?rido brasileiro. Foram feitas 11 amostragens da fauna de macroinvertebrados bent?nicos e de par?metros f?sico-qu?micos da ?gua em um riacho de primeira ordem da bacia hidrogr?fica do rio Piranhas-A?u durante o per?odo de mar?o a julho de 2009. Foram encontradas 25 fam?lias de organismos sendo 21 destes da classe Insecta. A fam?lia Chironomidae foi a mais abundante em todo per?odo amostral e foi representada por 19 g?neros. As maiores densidades de organismos e riqueza taxon?mica ocorreram no per?odo em que o riacho estava secando e as menores no per?odo das maiores precipita??es. Apenas as fam?lias de Diptera, Chironomidae e Ceratopogonidae, ocorreram durante todo per?odo amostral, sugerindo que estes organismos possuem melhores mecanismos de adapta??es frente ?s cheias e secas. Al?m disso, estes dois grupos pareceram ser os colonizadores prim?rios neste ambiente. Entre os quironom?deos, o g?nero Paratendipes dominou o per?odo de cheias enquanto Tanytarsus foi mais abundante no per?odo secando do riacho. Nosso estudo demonstrou que as flutua??es hidrol?gicas foram os fatores que mais influenciaram a comunidade dos macroinvertebrados bent?nicos no riacho, e assim, estrat?gias visando a conserva??o e gest?o destes ambientes devem considerar estas flutua??es

No Brasil, ela atinge o Semi?rido, amea?ando a fertilidade dos solos e a biodiversidade da Caatinga, bioma que s? existe no pa?s e ainda n?o ? completamente conhecido pela ci?ncia. A continua??o do processo pode ainda por em risco a seguran?a alimentar e h?drica e provocar a migra??o de milhares de pessoas. As iniciativas governamentais de combate ao problema, no entanto, n?o passaram do ?mbito da formula??o de pol?ticas ? a??o, e a sociedade tamb?m parece n?o perceber a urg?ncia da quest?o. Uma das formas de promover o engajamento social ? a divulga??o de informa??es pelos meios de comunica??o de massa, mas suas narrativas podem estar marcadas por interesses pol?ticos e econ?micos. Assim sendo, o objetivo geral deste trabalho ? analisar a produ??o cient?fica e a narrativa da m?dia impressa brasileira sobre desertifica??o. Nessa perspectiva, inicialmente foi realizado um panorama da produ??o cient?fica sobre o tema atrav?s de an?lise de artigos cient?ficos publicados sobre desertifica??o no Semi?rido brasileiro entre 2005 e 2014. Em seguida, not?cias e reportagens publicadas pelo jornal impresso Folha de S. Paulo entre 1994 e 2015 foram submetidas ? an?lise de conte?do. A produ??o cient?fica aumentou ao longo do tempo, mas a maior parte n?o ? acess?vel nas principais bases de dados internacional e nacional, possui car?ter disciplinar e n?o vem sendo continuada ao longo do tempo. J? o jornal impresso raramente fala sobre desertifica??o, e quando o faz ? de maneira descontextualizada ou catastr?fica, sem espa?o para o contradit?rio, dando pouca voz aos cientistas e quase nenhuma ? sociedade. ? necess?rio, portanto, investir mais em pesquisas multidisciplinares e de longo prazo que compreendam o problema e busquem solu??es na sua integralidade; ao mesmo tempo incentivar a participa??o social nas discuss?es cient?ficas, na formula??o de pol?ticas e na gest?o de estrat?gias de combate ? desertifica??o atrav?s da divulga??o de informa??o contextualizada, cr?tica e continuada. / Being a serious environmental issue, the addressing of desertification relies on scientific understanding of its complex ecological, social and climatic relations. Caatinga is a unique biome in the Semi-arid region of Brazil still uncharted by science and its soil fertility and biodiversity face serious threat as desertification advances and jeopardizes food and water resources for thousands of people, which leads to migration influx. Governmental response has not been able to yield substantial actions to tackle the issue and society unfortunately seems not to sense the urge of such matter. One way to promote social engagement about the subject has to do with propagating related information in spite of political and economical interests lurking the narrative of mass media in Brazil. The focus of this paper is to analyze the narrative of Brazilian press regarding desertification, also including a view on science press. A panorama of scientific production was made through scientometrical analysis of scientific papers published between 2005-2014 and content analyses of news and reports printed and published byFolha de S?o Paulo from 1994 through 2015. An increase of scientific production for disciplinary purposes was noticed, although discontinued eventually as access to most papers on major national and international databases remain unreachable. On printed newspaper, approach to the subject is rare and often happens in a decontextualized or catastrophic-toned manner, not allowing space for opposite views, hence offering little voice to scientists and almost none to society. Thus, it becomes necessary to invest in long term multidisciplinary, solution-oriented, researches that deepen comprehension of subject matter and enable society to take part in scientific discussion as well as formulating policies and managing strategies to tackle desertification with the aid of propagating continuous, critical and contextualized information.

Recent evidence has shown variations in the dynamics, structure and floristic composition of the caatinga, which justifies the need for studies focusing on different substrates. A floristic study of the caatinga ecoregions Depress?o Sertaneja Meridional and Raso da Catarina in the municipality of Tucano, Bahia, Brazil, is of special interest because both substrates occur in a local scale, letting the opportunity to broaden our knowledge on ecological heterogeneity within the Caatinga biome. In the current study we carried out a floristic survey of 14 sites distributed throughout the ecoregions of caatinga in Tucano. We found high species diversity in the caatingas of Tucano when compared to other areas in northeastern Brazil. A total of 451 species, 288 genera, and 82 families were collected. The most species rich families are Leguminosae and Euphorbiaceae. There occur 226 species in the sites on crystalline basement, whereas 284 species were collected in the sandy areas. The ecoregions were only 13% similar in floristic composition. We found strong differences between the ecoregions with respect to floristic composition and predominant plant habit as proxy for phytophysiognomy. Overall, our results reinforce the hypothesis of two distinct biotas that assembly the caatinga dry woodlands. / A vegeta??o de caatinga do nordeste brasileiro ocorre principalmente sobre solos derivados de rochas cristalinas pr?-cambrianas e sobre cobertura arenosa de bacias sedimentares. Evid?ncias recentes t?m demonstrado varia??es na din?mica, estrutura e composi??o flor?stica da caatinga, o que fundamenta a necessidade de estudos com enfoque nos diferentes substratos. O presente estudo flor?stico das ecorregi?es de caatinga, Depress?o Sertaneja Meridional e Raso da Catarina, no munic?pio de Tucano, Bahia, ? de especial interesse porque h? esses dois substratos em escala geogr?fica local, permitindo ampliar o conhecimento sobre a heterogeneidade do Dom?nio da Caatinga. Neste trabalho ? apresentado um invent?rio flor?stico de 14 localidades nas duas ecorregi?es de caatinga. Em conjunto, as caatingas amostradas apresentaram uma alta riqueza flor?stica em compara??o com outras ?reas no nordeste do Brasil. Foram coletadas 451 esp?cies, 288 g?neros e 82 fam?lias. A maior riqueza em esp?cies foi das Leguminosae, seguida por Euphorbiaceae. Nas localidades sobre substrato derivado do embasamento cristalino ocorreram 226 esp?cies, enquanto nas de substrato arenoso ocorreram 284 esp?cies. A propor??o de esp?cies em comum nas duas ecorregi?es foi apenas 13%. Diferen?as em composi??o flor?stica refor?am a hip?tese de duas biotas distintas associadas aos dois principais tipos de substrato, que comp?em a vegeta??o da caatinga.

Historicamente, a a??o estatal, quando presente, tratou de priorizar a constru??o de grandes obras de reservat?rios de ?gua, que acabaram fortalecendo a chamada ?ind?stria da seca?. No final da d?cada de 1990, em meio a um grande per?odo de estiagem na regi?o semi?rida brasi-leira, diversas entidades da sociedade civil se juntam para criar a Articula??o Semi?rido Bra-sileiro (ASA), institui??o cujo objetivo ? coordenar a??es de conviv?ncia com o semi?rido, dentre elas, o de democratizar o acesso ? ?gua, que se fez principalmente por meio da implan-ta??o do Programa Um Milh?o de Cisternas (P1MC) a partir do uso de Tecnologias Sociais. A proposta prev? a constru??o de cisternas para capta??o e armazenamento de ?guas pluviais, com o objetivo de abastecimento humano.

However, much of the population still doesn?t have access to water. Public policies and government programs aimed at this region are still far from pro-moting decentralization for the democratization of access to water. Historically, State action, when present, tried to prioritize the construction of large works of water reservoirs, which ended up strengthening the so-called "drought industry". At the end of the 1990s, in the midst of a great period of drought in the Brazilian semi-arid region, several civil society entities come together to create the Articulation of the Brazilian Semi-Arid (ASA). The institution was to coordinate actions to coexist with the Semi-Arid region among them and to democra-tize access to water, which was done mainly through the implementation of the One Million Cisterns (P1MC) Program. The proposal provided for the construction of cisterns to capture and store rainwater, with the objective of human supply. This action has been the object of numerous academic and political debates that seek to highlight the limits and possibilities of this policy. Thus, the objective of this research was to carry out an analysis of the P1MC pub-lic policy already in place and, in the implementation phase, with the purpose of understand-ing its capacity as strategies for coexistence with the semi-arid region for farmers, farmers and rural dwellers. Apodi-RN. The research has a qualitative nature, with semi-structured interviews with the technicians linked to the Coordination of ASA Potiguar, as well as with the beneficiaries of the P1MC public policy. The results indicate the program is dependent upon rainfall in the region. If there is little or no rainfall the P1MC is less effective therefore it is necessary to promote access to water for beneficiary families in other ways. It was also found that the P1MC Program contributes to the reduction of the painfulness of women's work, since it is no longer necessary to go to other localities to obtain water for consumption by the family; The P1 + 2 Program also contributes to maintaining small crops in the benefi-ciaries' homes; The implementation of the Programs provided greater organization, as it pro-moted the creation of Community Associations in communities that did not have.

A partir da d?cada de 1980, no processo de redemocratiza??o do pa?s de buscar alternativas para o desenvolvimento do semi?rido brasileiro, come?aram a existir algumas mudan?as na interven??o na regi?o a partir das organiza??es da sociedade civil, que passaram a realizar projetos com base na ideia de que ? poss?vel e necess?rio conviver com o semi?rido, representando a transi??o paradigm?tica na qual o modelo de ?combate ? seca? ? criticado em favor da ?conviv?ncia com o semi?rido?. Diante disso, este estudo objetivou analisar os resultados do Programa Um Milh?o de Cisternas Rurais (P1MC) diante dos indicadores de efic?cia, efici?ncia e efetividade. O programa, idealizado pela sociedade civil em 1999, apresenta como componentes a mobiliza??o, o controle social, a capacita??o, a comunica??o, o fortalecimento institucional e a constru??o de cisternas de placas de 16 mil litros para capta??o de ?gua de chuvas por meio de calhas no telhado do domic?lio rural. A pesquisa foi do tipo descritiva, o universo compreendeu os 10 territ?rios do Rio Grande do Norte, a abordagem foi quantitativa e qualitativa. Para o tratamento dos dados, utilizou-se an?lise envolt?ria de dados, na etapa quantitativa, e an?lise de conte?do, na etapa qualitativa, tendo como fonte de coleta entrevistas estruturadas com atores do P1MC. Os resultados apontaram que, em termos de efic?cia, representada pelas metas f?sicas pr?-estabelecidas, o programa ficou aqu?m do esperado; quanto ? efici?ncia, destacaram-se os territ?rios de Sert?o do Apodi, A?u-Mossor? e Mato Grande. Na rela??o popula??o rural versus cisternas constru?das, no tocante ? efetividade, verificou-se que os pressupostos do programa s?o atendidos, os participantes compreendem que o programa n?o tem como finalidade ?nica a constru??o da cisterna, mas sim proporcionar mudan?as na vida das pessoas a partir dela, o que converge com os objetivos do programa, representando uma a??o bem-sucedida. / Water scarcity is a recurrent problem in the Brazilian semi-arid, more precisely in the Northeast. The first initiatives, of attention to drought, emerged through public social actions of "salvation", mitigation of drought consequences. It lasted, until the 1980s, this perspective of "drought relief". From the 1980s, with the democratization of the Country and the state reform, new alternatives for the development of the Brazilian semi-arid began to emerge from civil society organizations, which began to implement projects based on the ideal that it is possible and necessary to coexist with the semi-arid. This movement represented a paradigmatic inflection - instead of "drought relief" emerges "coexistence with the semi-arid". This study lies, therefore, in this new moment of public actions aimed at semi-arid, assuming the intent to systematize results of the One Million Rural Cisterns Program (P1MC) in front of efficacy, efficiency and effectiveness indicators. The Program, designed and implemented by civil society organization since 1999, has as components mobilization, social control, training, communication, institutional strengthening and building of plates cisterns of 16,000 liters for rain water harvesting through gutters on the roof of the rural home. The research was descriptive, the universe comprised the 10 territories of Rio Grande do Norte, the approach was quantitative and qualitative. For the treatment of quantitative data, data envelopment analysis (DEA) was used through Siadv software and, in the qualitative stage, content analysis with assistance of NVivo 11 software, having as source of collection structured interviews with the actors of P1MC. The quantitative stage led to the determination of efficiency and efficacy indicators, while the qualitative stage enabled the interpretation of effectiveness, occurred based on the five principles expressed in P1MC by Brazilian Semi-Arid Articulation (ASA), a network of non-governmental organizations responsible for the design from the Program.
