Análise da vulnerabilidade de Natal/RN frente às mudanças climáticas

The interaction between land and water, resulting from dynamic agents, such as wind, waves and tides, characterizes the coastal zone as a dynamic environment that is constantly disturbed and that may alter the balance of natural and man-made environment. Such modifications may be intensified when considering the climate change. This environment is highly attractive for the development of economic activities and urbanization, current scenario of the city of Natal. Weighing the economic importance for the state and the physical environment in which the capital of Rio Grande do Norte is inserted, this study aims to identify and analyze vulnerabilities and impacts caused by the rising sea level in the municipality. To that end, we defined a coastline, delimited areas susceptible to flooding and presented some flood scenarios. This way we could identify and analyze the impacts of each flood scenario in its respective section. Finally, it appears that the coastal zone in which Natal is inserted is a fragile area that requires actions aimed at mitigating vulnerabilities and facing the problem that caused the rise in the mean sea level (MSL), and mitigating the presented vulnerability framework; it is necessary to implement actions that effectively contribute to the protection and adaptation of the most fragile areas

Gênero, trabalho e saúde mental entre trabalhadoras rurais assentadas na região do Mato Grande Potiguar

The lack of studies aimed at the mental health of the rural population, the social, economic, familial and emotional impact that mental disorders produce and the vulnerability that women have in this context, lead us to believe in the need to investigate the mental health demands of female rural workers, in order to subsidize the development of more effective and culturally sensitive public health programs and policies that take into account the specificities of this population. The present study aims to investigate the prevalence of common mental disorders (CMD) and the possible factors associated with the emergence of such disorders among women living in a rural settlement in Rio Grande do Norte. This survey has a quantitative and qualitative character with an ethnographic approach. As methodological strategies, we made use of an adapted version of the socio-demographic and environmental questionnaire prepared by The Department of Geology/UFRN s Strategic Analysis Laboratory to evaluate the quality of life of the families from the rural settlement and the mental health screening test Self-Reporting Questionnaire (SRQ-20) to identify the prevalence of CMD in adult women from the community. Complementing the role of methodological tools, we use the participant observation and semi-structured interviews with women who presented positive hypothesis of CMD attempting to comprehend the crossings that build the subjective experience of being a woman in this context. The results point to the high prevalence of CMD (43.6%) and suggest the link between poverty, lack of social support, unequal gender relations and the occurrence of CMD. We also verified that the settled women do not access the health network to address issues relating to mental health and that the only recourse of care offered by primary health care is the prescription of anxiolytic medication. In this context, the religiosity and the work are the most important strategies for mental health support among women

Serviço Social e terceiro setor: considerações sobre as atuais relações e condições de trabalho para o Assistente Social em Natal

The present study analyses the actual relations and work conditions found in the third sector in Natal city, in the context of productive restoration and increasingly retraction from the State in providing Social Service before the new approach that has been destined to the social issue. The study talks about the work of the social worker when fighting the different expressions the social issue has, such as social service provision as a way of teamwork associated to work relations and conditions, to accessible resources and quality control management. These are elements that affect and interfere in the accomplishment and in the work of the social worker itself. The State s improvement, according to neoliberal-political precepts and increasingly retraction from the public investment in the areas of social concern (health, social welfare, assistance) and in the wage and employment policy, besides expanding the partnership with the public and private areas, in search for social services with quality, it has diversified the structures of the professional work with the growth of the so called third sector institutions. However, the absorption of the social workers by the third sector groups in general, has as major features the impoverishment of work relations, the maintenance of an unequal salary model, pointing out the deadline contracts and/or single tasks that generate work instability. The research debates, with a critical view and full perspective, over the conception of the third sector, interpreted as an action that expresses functions and values, treated as a real phenomenon generated from the restoration of the capital based on neoliberal principles. This study aims for responding what the established work relations are and under what work conditions the social worker has been fitting in the third sector and how such a reality echoes in the current work conditions for a social work in the city of Natal, before this new model of state intervention that transfers part of the social service provision to distinctive divisions of society, among them the so called third sector. The research results have shown that like the other workers the social worker passes through the same crises, dilemmas, advances and challenges that occur in the world of employment and which are expressed in the drop of salary average in the growth of contemporary contracts, unemployment, and in the ever more selective requirements to one be included in the social spaces, where the professional work is done, having as a result a greater impoverishment of work relations and conditions as well as more vulnerability as a salaried occupation

Sistemas de dunas do parque das Dunas e Barreiras do Inferno/Natal (RN: levantamento geológico /geofísico, elaboração do modelo deterministico e avaliação da vulnerabilidade/suscetibilidade

The current work was developed on the dune systems of the Parque das Dunas and Barreira do Inferno. These places are located in the cities of Natal and Parnamirim (RN, Brazil), respectively. This project has the purpose of developing the deterministic model on a specific blowout at Parque das Dunas, based in the geophysical interpretations of the lines gotten with the Ground Penetration Radar and the planialtimetric acquisitions of the topographical surface of the land. Also analyses of the vulnerability/susceptibility of these dune systems had been done in relation to the human pressures. To develop its deterministic model, it is necessary to acquire inner and outer geometries of the cited blowout. In order to depict inner geometries underneath the surface are used the GPR observing the altimetric control for topographical correction of the GPR lines. As for the outer geometries, the geodesic GPS gives us the planialtimetric points (x, y and z points) with milimetric precision, resulting in high-resolution surfaces. Using interpolation methods of the planialtimetric points was possible create Digital Elevations Models (DEM´s) of these surfaces. As a result, 1,161.4 meters of GPR lines were acquired on the blowout at the Parque das Dunas and 3,735.27 meters on the blowout at the Barreira do Inferno. These lines had been acquired with a 200 MHz antenna, except the 7 and 8 lines, for which we had been used a 100 MHz antenna. The gotten data had been processed and interpreted, being possible to identify boundary surfaces of first, second and third order. The first order boundary surface is related with the contact of the rocks of the Barreiras Group with the aeolian deposits. These deposits had been divided in two groups (Group 1 and Group 2) which are related with the geometry of stratum and the dip of its stratifications. Group 1 presented stratum of sigmoidal and irregular geometries and involved bodies where the reflectors had presented dips that had varied of 20 to the 28 degrees for the Parque das Dunas blowout and of 22 to the 29 degrees for the Barreira do Inferno blowout. Usually, it was limited in the base for the first order surface and in the top for the second order surface. Group 2 presented stratum of trough, wedge or lens geometries, limited in the base for the second order vi surface, where the corresponding deposits had more shown smoothed reflectors or with dips of low angle. The Deterministic and Digital Elevation Models had been developed from the integration and interpretation of the 2D data with the GOCAD® program. In Digital Elevations Models it was possible to see, for the localities, corridor or trough-shaped blowouts. In Deterministic Model it was possible to see first and second order boundary surfaces. For the vulnerability/susceptibility of the dune systems it was applied the methodology proposal by Boderè al (1991); however the same one did not show adequate because it evaluates actual coastal dunes. Actual coastal dunes are dunes that are presented in balance with the current environmental conditions. Therefore, a new methodology was proposal which characterizes the supplying and activity sedimentary, as well as the human pressures. For the methodology developed in this work, both the localities had presented a good management. The Parque das Dunas was characterized as a relic dune system and the Barreira do Inferno was characterized as a palimpsestic dune system. Also two Thematic Maps had been elaborated for the environmental characterization of the studied dune systems, with software ArcGis 8.3, and its respective data bases

Desenvolvimento de um sistema computacional para geração automática de mapas de vulnerabilidade como ferramenta de auxílio às ações de prevenção ao derramamento de óleo em áreas costeiras

The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coastal dynamic action promoting problems such as erosion and exposure of wells and pipelines along the shore. Thus came the improvement of such modifications, in search of understanding of the changes which causes environmental impacts with the purpose of detecting and assessing areas with greater vulnerability to variations. Coastal areas under influence oil industry are highly vulnerable and sensitive in case of accidents involving oil spill in the vicinity. Therefore, it was established the geoenvironmental monitoring of the region with the aim of evaluating the entire coastal area evolution and check the sensitivity of the site on the presence of oil. The goal of this work was the implementation of a computer system that combines the needs of insertion and visualization of thematic maps for the generation of Environmental Vulnerability maps, using techniques of Business Intelligence (BI), from vector information previously stored in the database. The fundamental design interest was to implement a more scalable system that meets the diverse fields of study and make the appropriate system for generating online vulnerability maps, automating the methodology so as to facilitate data manipulation and fast results in cases of real time operational decision-making. In database development a geographic area was established the conceptual model of the selected data and Web system was done using the template database PostgreSQL, PostGis spatial extension, Glassfish Web server and the viewer maps Web environment, the GeoServer. To develop a geographic database it was necessary to generate the conceptual model of the selected data and the Web system development was done using the PostgreSQL database system, its spatial extension PostGIS, the web server Glassfish and GeoServer to display maps in Web

Vulnerabilidade ambiental da zona costeira de Pititinga, Rio do Fogo, Rio Grande do Norte

This work presents a study on the environmental vulnerability of the coastal region of Pititinga, Rio do Fogo/RN. The coastal erosion of Pititinga beach was analyzed and considerated as one more process that produces environmental vulnerability in the area of study, taking into account its human and natural environment and establishing the relation between them, to understand the arrangement that produced its spatial configuration. The natural environment was expressed by thematics maps with geology, geomorphology, vegetation and soil themes, while the human environment was expressed by the use and occupation of the soil map. The coastal erosion was put in an erosion vulnerability map. The methodological procedure to generate the thematics maps, vulnerability maps and of the erosion coastal involved the bibliographic research, field visits with check-list form fill, collect and analysis of sediment sample, photo-interpretation techniques, integration of the information in a database, data store and spatial analysis in a Geographic Information System (GIS) ambient. The natural vulnerability map shows a predominancy of environments with low (29,6%) or medium (42,4%) vulnerability, pointed the frontal and mobile dune as the areas with the highest vulnerability. The environmental vulnerability map, presents a predominancy of environments with low vulnerability (53,8%), with the high vulnerability concentrated on Pititinga community. The coastal erosion vulnerability presented distinct behaviors on three sections among the coastal line according each one characteristics. Where there are frontal and transgressive dunes, vulnerability are, generally, medium or low, respectively, and in the absence of them, as what occurs in Pititinga community, the vulnerability is predominately very high

Estimativa da vulnerabilidade natural de aqüíferos: uma contribuição a partir da resistividade e condutância longitudinal

Este trabalho descreve os resultados obtidos com o método da eletrorresistividade usando a técnica da sondagem elétrica vertical (arranjo Schlumberger) aplicada em estudos ambientais envolvendo as águas subterrâneas. A vulnerabilidade natural de aqüíferos, importante ferramenta em estudos ambientais, pode ser estimada a partir de métodos geoelétricos, cujos parâmetros resistividade e condutância longitudinal, aliados ao tipo de ocorrência dos aqüíferos (livre a confinado) e profundidade do nível d'água, permitiram obter um índice de vulnerabilidade natural correspondente ao normalmente utilizado. Os resultados, aplicados em uma fase preliminar de estudos, são bons, permitindo um melhor direcionamento e programação das fases posteriores.
