Primary Health Care from the perception of women living in a rural area

AbstractOBJECTIVEUnderstanding the perception of women living in a rural area about the actions and services of Primary Health Care (PHC) in a municipality of southern Brazil, which is the only one regarded as predominantly rural.METHODA descriptive study of qualitative approach, carried out with women who lived in the countryside and required health services in the 15 days prior to collection.RESULTSThe results registered low fidelity to PHC attributes, focusing its functional axis on sickness, transforming the unit into small points of emergency care and a bureaucratic place where patients are referred to other types of services. The quality of service offered is compromised to offering quick, fragmented and unequal treatment in the rural context.CONCLUSIONThe findings of this study highlight the need for greater efforts in order to adequate the new care model in the development of appropriate actions as designated by PHC in the rural context studied.

Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest

Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam.) Mart. (Annonaceae) in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were applied to verify the ecological patterns of the mite community, besides the Student's t-test to compare the abundance between the fragments. We collected 27,365 mites of 37 species belonging to 11 families. Calacarus sp. (Eriophyidae) was the most abundant species, representing 73% of the total sampled. The abundance was greater in the urban fragment (67.7%), with the diversity index reaching only 25% of the theoretical maximum expected. Probably, these values might have been influenced by the location of this fragment in the urban area, being more homogeneous and submitted directly to the presence of atmospheric pollution. In this manner, X. aromatica is able to shelter a higher diversity of mites when inserted in preserved ecosystems, since the highest diversity of available resources allows the establishment of richer and most diverse mite community.

Latitudinal gradient effect on the wing geometry of Auca coctei (Guérin)(Lepidoptera, Nymphalidae)

Latitudinal gradient effect on the wing geometry of Auca coctei (Guérin) (Lepidoptera, Nymphalidae). When the environmental conditions change locally, the organisms and populations may also change in response to the selection pressure, so that the development of individuals may become affected in different degrees. There have been only a few studies in which the patterns of wing morphology variation have been looked into along a latitudinal gradient by means of geometric morphometrics. The aim of this work was to assess the morphologic differentiation of wing among butterfly populations of the species Auca coctei. For this purpose, 9 sampling locations were used which are representative of the distribution range of the butterfly and cover a wide latitudinal range in Chile. The wing morphology was studied in a total of 202 specimens of A. coctei (150 males and 52 females), based on digitization of 17 morphologic landmarks. The results show variation of wing shape in both sexes; however, for the centroid size there was significant variation only in females. Females show smaller centroid size at higher latitudes, therefore in this study the Bergmann reverse rule is confirmed for females of A. coctei. Our study extends morphologic projections with latitude, suggesting that wing variation is an environmental response from diverse origins and may influence different characteristics of the life history of a butterfly.

Use of the swat model for hydro-sedimentologic simulation in a small rural watershed

Mathematical models have great potential to support land use planning, with the goal of improving water and land quality. Before using a model, however, the model must demonstrate that it can correctly simulate the hydrological and erosive processes of a given site. The SWAT model (Soil and Water Assessment Tool) was developed in the United States to evaluate the effects of conservation agriculture on hydrological processes and water quality at the watershed scale. This model was initially proposed for use without calibration, which would eliminate the need for measured hydro-sedimentologic data. In this study, the SWAT model was evaluated in a small rural watershed (1.19 km²) located on the basalt slopes of the state of Rio Grande do Sul in southern Brazil, where farmers have been using cover crops associated with minimum tillage to control soil erosion. Values simulated by the model were compared with measured hydro-sedimentological data. Results for surface and total runoff on a daily basis were considered unsatisfactory (Nash-Sutcliffe efficiency coefficient - NSE < 0.5). However simulation results on monthly and annual scales were significantly better. With regard to the erosion process, the simulated sediment yields for all years of the study were unsatisfactory in comparison with the observed values on a daily and monthly basis (NSE values < -6), and overestimated the annual sediment yield by more than 100 %.

Diagnóstico rápido e dialogado em estudos de desenvolvimento rural sustentável

O principal objetivo deste trabalho foi verificar se a suposição de predominância da agricultura familiar na microbacia do Taquara Branca, Sumaré, SP, poderia ser sustentada com base em informações concretas. Foi possível a utilização de amostragem probabilística, pois estava disponível um mapa com os limites das 106 propriedades da microbacia, sendo sorteadas 33 delas para a aplicação de questionários do tipo cross-section. A técnica multivariada empregada foi a análise de agrupamentos, para a qual foi utilizado o procedimento PROC CLUSTER do SAS. Nessa análise só foram considerados os dados referentes aos 22 respondentes que exerciam atividade agrícola. Após a análise unidimensional, algumas perguntas foram selecionadas com base na variabilidade entre as respostas e, a partir destas, construíram-se as variáveis necessárias para se proceder à análise multidimensional. A análise de agrupamento permitiu identificar claramente três grupos naturais entre as 22 propriedades. De acordo com as características dos componentes de cada grupo, foi possível classificá-los em: grupo 1, doze propriedades de agricultura familiar; grupo 2, seis propriedades de agricultura não familiar em pequenas áreas; e grupo 3, quatro propriedades de agricultura não familiar em grandes áreas. Embora não seja predominante (apenas 36%), a agricultura familiar é o grupo mais freqüente na microbacia do Taquara Branca.

Sistema integrado de avaliação de impacto ambiental aplicado a atividades do Novo Rural

O objetivo deste trabalho foi apresentar o sistema de Avaliação Ponderada de Impacto Ambiental de Atividades do Novo Rural (APOIA-NovoRural), que consiste de um conjunto de planilhas eletrônicas (plataforma MS-Excel) que integram 62 indicadores da performance ambiental de uma atividade econômica em um estabelecimento rural. Cinco dimensões de avaliação foram consideradas: ecologia da paisagem, qualidade ambiental (atmosfera, água e solo), valores socioculturais, valores econômicos e gestão e administração. Os indicadores foram construídos em matrizes de ponderação, nas quais dados quantitativos, obtidos em campo e laboratório, foram automaticamente transformados em índices de impacto, expressos graficamente. O índice de impacto de cada indicador foi traduzido a um valor de utilidade, empregando-se funções e coeficientes especificamente derivados para cada indicador. Os valores de utilidade foram agregados para compor o Índice de Impacto Ambiental da atividade avaliada. Os resultados da avaliação permitem ao produtor/administrador averiguar quais atributos da atividade podem estar desconformes com seus objetivos de sustentabilidade e ao tomador de decisões a indicação de medidas de fomento ou controle das atividades, segundo planos de desenvolvimento local; proporcionam, ainda, uma unidade de medida objetiva de impacto para auxiliar na qualificação e certificação de atividades agropecuárias.

Simulação da dinâmica do carbono do solo numa microbacia rural pelo modelo Century

O objetivo deste trabalho foi combinar o modelo Century com técnicas de geoprocessamento e sensoriamento remoto, para avaliar a dinâmica espaço-temporal do carbono orgânico total do solo (COT). O estudo foi implementado numa microbacia rural, na encosta superior do Nordeste do Rio Grande do Sul, RS, que apresentava inicialmente uma cobertura florestal que foi convertida para agricultura, ao longo de 80 anos. A calibração adequada do modelo, principalmente dos parâmetros relacionados à decomposição do COT, nos anos iniciais de exploração agrícola, foi fundamental para possibilitar a simulação coerente dos valores de COT. Em relação à distribuição espacial do COT, foi verificado que o maior impacto da agricultura, sobre o estoque original de COT, ocorreu nas áreas sob cultivo desde 1925, nas quais se constatou decréscimo de 58,2% do COT. Verificou-se que a integração do Century com um sistema de informações geográficas torna possível o estudo da dinâmica espaço-temporal do COT e a realização de inventários relativos à distribuição do COT.

Ant species distribution along a topographic gradient in a "terra-firme" forest reserve in Central Amazonia

In Amazonia, topographical variations in soil and forest structure within "terra-firme" ecosystems are important factors correlated with terrestrial invertebrates' distribution. The objective of this work was to assess the effects of soil clay content and slope on ant species distribution over a 25 km² grid covering the natural topographic continuum. Using three complementary sampling methods (sardine baits, pitfall traps and litter samples extracted in Winkler sacks), 300 subsamples of each method were taken in 30 plots distributed over a wet tropical forest in the Ducke Reserve (Manaus, AM, Brazil). An amount of 26,814 individuals from 11 subfamilies, 54 genera, 85 species and 152 morphospecies was recorded (Pheidole represented 37% of all morphospecies). The genus Eurhopalothrix was registered for the first time for the reserve. Species number was not correlated with slope or clay content, except for the species sampled from litter. However, the Principal Coordinate Analysis indicated that the main pattern of species composition from pitfall and litter samples was related to clay content. Almost half of the species were found only in valleys or only on plateaus, which suggests that most of them are habitat specialists. In Central Amazonia, soil texture is usually correlated with vegetation structure and moisture content, creating different microhabitats, which probably account for the observed differences in ant community structure.

Diversity of springtails (Hexapoda) according to a altitudinal gradient

The objective of this work was to elevate gradient effect on diversity of Collembola, in a temperate forest on the northeast slope of Iztaccíhuatl Volcano, Mexico. Four expeditions were organized from November 2003 to August 2004, at four altitudes (2,753, 3,015, 3,250 and 3,687 m a.s.l.). In each site, air temperature, CO2 concentration, humidity, and terrain inclination were measured. The influence of abiotic factors on faunal composition was evaluated, at the four collecting sites, with canonical correspondence analyses (CCA). A total of 24,028 specimens were obtained, representing 12 families, 44 genera and 76 species. Mesaphorura phlorae, Proisotoma ca. tenella and Parisotoma ca. notabilis were the most abundant species. The highest diversity and evenness were recorded at 3,250 m (H' = 2.85; J' = 0.73). Canonical analyses axes 1 and 2 of the CCA explained 67.4% of the variance in species composition, with CO2 and altitude best explaining axis 1, while slope and humidity were better correlated to axis 2. The results showed that CO2 is an important factor to explain Collembola species assemblage, together with slope and humidity.

Modelo multicritério aditivo na geração de mapas de suscetibilidade à erosão em área rural

O objetivo deste trabalho foi avaliar a geração de um mapa de suscetibilidade à erosão, em área rural, no Município de Guararapes, SP, por meio de modelo multicritério aditivo. Foram utilizados mapas digitais dos temas: relevo (declividade e comprimento das rampas); pedologia (obtida em campo); uso e cobertura das terras da região; e interpretação do modelo digital de elevação. Os mapas digitais foram tratados em ambiente de sistema de informação geográfica, por meio do método multicritério aditivo, e validados pelo modelo da equação universal de perda de solo (USLE). Foram geradas cinco classes de suscetibilidade à erosão: baixa, moderada, alta, muito alta e altíssima. O mapa de risco obtido por multicritério aditivo teve boa correspondência com o modelo USLE. O mapa de suscetibilidade à erosão pode ser aplicado ao planejamento agrícola e ambiental da área rural do Município de Guararapes.
