Zoneamento agroecológico do município e Apodi/RN

The aim of the paper is to carry out a geo-environmental characterization of Apodi District, in Rio Grande do Norte State, as a support to agro-ecological zoning studies on that region. The first methodology action was to accomplish a comprehensive bibliography review on the subject, followed by observation of satellite images and their processing throughout geographic information systems (SIG), as well as technical visits to various places in order to verify in loco the preset conditions of the soil and the environmental degradation problems in those areas. The paper also presents data about the socio-economy and physic-natural local aspects of the land, required to the implementation of zoning studies which are one the most important tool to the planning and organization of the use of the soil containing a sustainable cattle-raising activity. As a result, thematic maps describing the physic-natural features and analysis of the socio-environment data, indispensable to the agro-ecological zoning, have been provided

Zoneamento geoambiental como subsídio ao planejamento territorial municipal: estudo de caso para Currais Novos/RN

This paper presents the master plan and geoenvironmental zoning natures as instruments of environmental planning and management. The discussion of territory environmental planning is guided by two directions: at first the environmental elements involved in planning and the another is the implementation of these instruments at the municipal territory. To analyze the planning directed of the municipal territory we consider the fragments of its, represented by country and urban. The master plan inside of the Estatuto da Cidade (City Statute) and the geoenvironmental zoning are directed to territorial environmental planning. Regarding of the master plan the first challenge has been the spacial area that the plan can cover. It is necessary to prepare master plans that could include all the territory. The environmental zoning are directed for the territory totality.In this sense, the geoenvironmental zoning of the Currais Novos was done in the totality of the municipal territory and guided by the environmental physics variables. The geoenvironmental zoning sets in a planning and ordering of the territory instrument based in the landscape analysis. Therefore grounded in the Geosystems‟s Theory this work has like a main objective to propose a geoenvironmental zoning for the Currais Novos Municipality in RN. So, was used an analysis technique suggested for Bardin (2010) and the Currais Novos‟s physical environment characterization through of the fieldwork and cartographic data vectorization, beyond the image‟s treatment SRTM. The geoenvironmental systems definitions were based in the suggestion of Cestaro, et al. (2007) support in Bertrand (1968). For both were identified five geoenvironmental systems: Borborema Plateau, Residual plateau, Chapada da Serra de Santana, semiarid river valley and lagoon valley and eleven geoenvironmental subsystems: Borborema Plateau Western Slope, Isolated Massif of the Borborema Plateau, Residual Crest, Residual Massif, Erosional Scarp of the Chapada, flat top plateau, fluvial plains, temporary river of the semiarid and ornamental water or sluice

Proposta de zoneamento geoambiental do município do Crato/CE

The geo-environmental zoning is an important means to plan the management of the territory, once it is the result of integration of different elements of the physical environment. The Municipality of Crato has a diversity of geo-environmental systems due to its complex landscape, which characterization and delimitation will contribute to the most appropriate occupation and the fewer prejudicial to municipal area. This study, which was supported by geo-systemic theory, searched to reach the following objectives: to elaborate a proposal of geo-environmental zoning; to characterize identified and demarcated geo-environmental systems, including their potentiality and limitations of land use and human occupation; and to generate a database on digital maps through GIS Geographic Information System. Four geo-environmental systems were identified (Chapada do Araripe: plateau and hillside, Massif and residual crest, Sertão of peripheric southern depression and fluvial Plains) and ten geo-environmental subsystems (Eastern plateau covered by cerradão/cerrado, Western plateau covered by cerrado/carrasco, Northern-west hillside, central residual Massif, Northern Residual Massifs, Sertaneja depression dominated by sedimentary materials, Sertaneja depression dominated by embasement crystalline material; wet fluvial plains and dry fluvial plains). The identified system and subsystem are similar to those proposed by FUNCEME in spite of some changes due to the more detailed mapping

Zoneamento ambiental do Município de Aquiraz-CE

The Metropolitan Region of Fortaleza (RMF) is composed by thirteen cities, where is call the attention of Aquiraz. The city has a excellent resort area and a big importance in socioculture and historics aspects. It was one of the first village of Ceará, and it was founded in 1699, with was also the capital of the state until 1726. The urban local development has been disorganized in the last decades, the fact is, insert of turismon in its coast, and it is unable with alow capacity of the natural suppots, configuring unsustainable and et environment ambience. Considering as a turistic region, it is preoccupy, been necessart to create a better control of the nature of the region by the users. The environmental zoning in this work it is to plan of adequate form the use of the ground based in the management of the interests and the social and economic necessities in accord with the preservation of the environment and the natural characteristics of the city. The same is one great instrument planning where use to be analized in differents ways: social, ambiental, economical and institucional, and promove alternatives of use and occupation of the land to recreate the city. The methodo used to get the real objective, englobed zonal maps in ambiental unities and others themes (geologic/geomorphologic) since than the images from satelities LANDSAT and SPOT and fotografies under position of maps, secundaries listes gets in publics department, bibliographie, informations by the local populations. This prociduries mede easy to create maps, geologic/geomorphologic, of use and occupation the earth and the environmental zoning to analize the dynamic and the working of each ambiental unity of the city Aquiraz wich is located by map of this job. As a result of this job was confectionated the environmental zoning map of Aquiraz wich was divided in five ambiental unities and restrictions areas of occupation: unit I Littoral Plain (zoning with serious restrictions to the occupation); unit II Sub-Littoral Plain (improper zoning to the occupation); unit III between tray zoning Pré-Littoral and Peripheral Depression (improper zoning to the occupation); unit IV Strativism reserve of the plug (zoning used more under control in its occupation) and unit V Fluvial Plain Localities of the Indians Jenipapo-Kaninde/ locality Quilombolas (zoning used more without official regulation). With proposal in the ambient units above one expects that it has a reduction of the ambient degradation and protection of the local biodiversity of the city of Aquiraz in the State of the Ceará

Zoneamento bioclimático da ovinocultura no Estado do Paraná

Utilizaram-se 45 fêmeas ovinas adultas (15 Hampshire Down [HD], 15 Texel [TE] e 15 Ile de France [IF]), para propor um zoneamento bioclimático da ovinocultura no Estado do Paraná. Mediram-se a temperatura retal (Tr), da epiderme (Te), do interior do velo (Tiv) e da superfície do velo (Tsv); a frequência respiratória (Fr); a temperatura do ar (Ta), pressão de vapor (e), velocidade do vento (v) e carga térmica radiante (CTR). O Índice de Conforto Térmico utilizado foi ICT= 0,6678Ta + 0,4969e + 0,5444Tg + 0,1038v. A regressão do ICT sobre Tr mostrou efeito quadrático para as três raças. Para ICT=24,3, 27,3 e 20,6, os valores de Tr foram respectivamente: 39,10ºC para a raça HD, 39,05ºC para TE e 39,09ºC para IF, atingindo 40,40; 40,50; e 40,28ºC, respectivamente, para ICT=58. As três raças aumentaram sua Tr a partir de ICT=26, com a TE apresentando menor Tr até o valor ICT=46; neste ponto, as três raças foram semelhantes, tendo a TE apresentado maiores valores. Para ICT igual a 27,6; 29,7; e 27,0, os valores de Fr foram, respectivamente, 89,63; 77,08; e 78,77 resp./min., para as raças HD, TE e IF. A raça TE apresentou menor Fr (77,08 resp./min.), para ICT=29,7 e para ICT=48, valores semelhantes aos da IF (181,96 resp./min.); a partir deste índice, passou a ser maior que as demais raças, atingindo valores de 288,66 resp./min. no ICT=56, porém inferior à HD (289,01 resp./min.). Neste índice, a raça IF foi a que apresentou a menor Fr (275,72 resp./min.). Uma extensa faixa ao longo do litoral do Estado, entrando cerca de 200 km para o interior até os limites das cidades de Castro, Telêmaco Borba, Laranjeiras do Sul e Pato Branco, permite a criação das três raças, sem exigir grandes esforços de termorregulação.

Zoneamento agroclimático da cultura da mangueira no Estado do Piauí

O presente trabalho teve como objetivo realizar o zoneamento agroclimático da cultura da mangueira no Estado do Piauí. Foram utilizados dados médios anuais de precipitação e temperatura do ar, de 15 municípios do Piauí, representativos das principais regiões do Estado para a elaboração do balanço hídrico e a obtenção do Índice de Umidade (Im). Foram adotadas as seguintes faixas de Índice de Umidade (Im): - Aptidão plena A, Im < -40; - Aptidão plena B, -40 < Im <-20. O critério utilizado na divisão do Estado, em zonas térmicas, baseou-se nas normais de temperaturas médias do mês mais quente (Tq) para cada local. Assim sendo, as faixas A e B, com aptidão plena, do ponto de vista hídrico, foram subdivididas em duas subzonas: Aptidão plena A1: (Tq < 29 ºC), Aptidão plena A2: (29 ºC < Tq <31 ºC) e Aptidão plena B1: (Tq < 29 ºC), Aptidão plena B2: (29 ºC < Tq <31 ºC), para atender ao critério térmico. Com base nas cartas de Tq e Im, foram definidos os limites para as diferentes zonas de aptidão climáticas para o cultivo de manga. À luz dos critérios utilizados e com base na literatura consultada, o Estado do Piauí não apresenta nenhuma restrição climática para o cultivo comercial da mangueira.

Estudo do peso e da idade gestacional de recem-nascidos e dos fatores que interferem no desenvolvimento fetal: nivel socio-economico, fatores maternos, fetais e placentarios

The present study was undertaken to determine the importance of socioeconomic factors (family income), urban or rural family location, parity, maternal age, the presence of maternal and fetal pathologies as well as placental abnormalities on the weight and gestational age of 566 newborns. The highest incidence of newborns with low birth weight for gestational age was significantly more frequent in urban populations when the mothers were from low socio-economic levels. In mothers from low socioeconomic levels infants with low birth weight for gestational age were seen in greater proportion among primaparas and had a tendency to be higher in mothers aged less than 20 years; prematurity was highest in mothers ≥ 30 years old and significantly higher from the 8th gestation on. Maternal and fetal pathologies emphasized these characteristics and placental pathologies were not correlated with the distribution of weight and length of gestation. In mothers of high socioeconomic levels age and parity were not correlated with weight and gestational age of the newborns.

Os complexos granitoides Cunhaporanga e Tres Corregos (PR) zoneamento magmatico e implicacoes geotectonicas

Geological, petrographic, chemical and zircon typology data from the Cunhaporanga and Tres Corregos granitoid complexes are presented and discussed. Both complexes of Late Precambrian age evolved by crystal fractionation. By its zircon typology the Cunhaporanga is classified as a low temperature calc-alkaline batholith and the Tres Corregos as a medium temperature calc-alkaline complex. This classification implies a major participation of mantle material during the generation of the Tres Corregos magma in relation to the Cunhaporanga ones. In this way both complexes define a magmatic zoning from NW to SE done by a increasing in the depth of magma generation. -from English summary

Zoneamento geoambiental aplicado ao planejamento da gestão ambiental e territorial do município de Colorado D'Oeste, RO

This research is based on the physical characterization of the environment to support definition of the best land use for the county of Colorado D'Oeste, in State of Rondônia, Brazil. Remote sensing and geoprocessing techniques were applied to support the preparation of a Geoenvironmental Zoning, which was used to define strategies of territorial and environmental management in that county. Digital and analogical remote sensing products, acquired by satellites, and additional cartographic and thematic maps allowed a morphostructural analysis to define low and high structural associated study site tectonic. Subsequently, this information was used to support analysis of the physiographic compartmentation of the study area. Based on this study information, it is possible to define geoenvironmental subzones and local hidrological regime, soils, mineral components, texture, color, and sedimentary materials. By integrating previous described information, a synthesis cartographic map generated. Accordingly, this Cartographic Sheet spatially defined the best land use over the study area, indicates zones for conservation, agricultural, and regeneration (areas that should be recovered). Finally, the results of this research can contribute and support governmental and non-governmental organization and local communities could improve land use and soil management, avoiding natural resource destruction and future land scarcity in the county of Colorado D'Oeste.

Zoneamento do parque ecológico de ourinhos SP

The aim of this study was to carry out a zoning in the municipal ecological park of Ourinhos, SP, located southwest of São Paulo State, aiming to subsidize the planning and management of this area. With this purpose it was made an inventory of the landscape resources of this park with hypsometry, declivity, use of soil and zoning mappings. From this zoning, we analyzed the possibilities of implementing purposes of use, with the objective of preserving this area, minimizing the negative environmental impacts. Thus, this research was of extreme importance, since it allowed to identify and rank, in the territory, areas or sectors that are priority to the development of activities, as well as contribute to the conservation of natural and socio-cultural heritage.
