Agroindústria canavieira e unidade de conservação: Impactos Sociais na comunidade de pescadores de Baía Formosa (RN)

The conservation unities emerged in response to the environmental damages. In the Atlantic Forest of the Brazilian Northeast, the most of the damages come from the sugar-cane agro-industry, especially by the deforestation for the introduction of sugar-cane fields and installation of the industry structure. Besides the damages over the biodiversity, there are critical social problems that affect the communities which survive using directly or indirectly the biome from the Atlantic Forest. The objective of this research is to analyze the social impacts on the fishermen of Baía Formosa/RN generated by the changes and socio-environmental transformations occurred starting the installation of a sugar-cane factory and the creation of a conservation area in the municipality of Baía Formosa/RN community. The research is based on a qualitative and diachronic perspective, for both approach, it was used the method of oral history in conjunction with the literature search and some technical and research tools such as direct observation, interview, records images and recordings . The results show that social and symbolic practices of the community in the conservation unit Mata Estrela last more strongly presented. Today fewer natural resources are used, due to factors such as limit access to forest and disappearance of some natural resources by deforestation. It is believed that the loss of free access to space for the community is the most significant negative impact, as promoted changes in the relationship of the community with the Star Forest that contributed to the fading of their social and symbolic practices. The loss of free access caused the decline in the practice of agriculture, which resulted in the loss of one of the means of social reproduction of the community

Impactos sócio-econômicos e ambientais da introdução da Tilápia do Nilo, Oreochromis niloticus, em açudes públicos do semi-árido nordestino, Brasi

The stocking of exotic fish, especially the tilapia, has become a common practice in the public reservoirs of the Brazilian semi-arid region. The stocking of tilapias has had as its main aim the improvement of the fisheries in the reservoirs and consequently the improvement of the socio-economic conditions of the families that have fishing as the main source of income. However, the environmental risks associated with this practice are high and can lead to a loss in aquatic biodiversity and to changes in the quality of the water. The object of this work was to quantify the socio-economic and environmental effects of the introduction of the Nile tilapia in the public reservoirs of the semi-arid northeastern Brazil. The analysis of the fish yield of 100 public reservoirs from 1970 to 2000 demonstrated that the introduction of the Nile tilapia apparently contributed to an increase in the total fish yield from the late 1970 s until the mid-1980 s. Nevertheless, from that time onwards the fish yield in these reservoirs has fallen into decline to levels inferior to those observed prior to the introduction of the tilápia. The analysis of the fishing activity statistics of the Gargalheiras reservoir located in the city of Acari, Rio Grande do Norte, demonstrated that the introduction of the Nile tilapia in the reservoir has not significantly increased the fish yield, the gross overall income, the gross per capita income nor the number of fishermen actively fishing in the reservoir. On the other hand, the analysis of the fishing activity statistics of the Gargalheiras reservoir has revealed a significant reduction in the captures of other commercially important fish species after the introduction of the tilapia. This result suggests that the Nile tilapia could have negatively affected other species of fish in the reservoir, contributing to the decline in their stocks. In order to assess the perception of the fishermen concerning the effects of the Nile tilapia over other species of fish and the quality of the water, questionnaires containing open and multiple choice questions were applied with 30 fishermen from the colony of the Gargalheiras reservoir. The great majority of the local fishermen stated that the tilapia is currently the most important species of fish to those who depend on fishing as a source of income and that they have not caused damage to other species of fish nor to the quality of the water in the reservoir. However, the results of the present work indicate that the alleged socio-economic benefits, employed to justify the introduction of the Nile tilapia in the reservoirs, are overestimated while the environmental impacts of the introduction of this exotic species are underestimated

Gestão por Competências em Organizações Públicas: O Processo de Transformação Organizacional e seus Impactos Junto aos Servidores na Secretaria Estadual de Administração e Recursos Humanos (SEARH/RN)

The state has changed over time in order to meet a society with increasingly stringent demands. Techniques of private means begin to be employed in an attempt to overcome the dysfunctions entrenched bureaucracy, making the machine faster. By federal law by the People Management Skills was established as a reference for the administration of Human Resources of the public sector in an attempt to develop professionally servers, based mainly on the three pillars of the model: the knowledge, skills and attitudes. This thesis aims at understanding, in the view of employees, the perceived impacts on the organizational changes occurring in the Department of Administration and Human Resources of the State of Rio Grande do Norte in order to implement a People Management Skills-based. It is a simple case study, characterized by the research during a certain period of time, collecting data in a real environment of an organization, in this case SEARH/RN. The procedures used in collecting data were the literature review, documental research and field research. We used a qualitative approach with exploratory and descriptive approach. Every reform was implemented in the institution and reported from there analyzed the impacts observed by the servers. As a result we observed a considerable advance in institutional activities, mainly relating to physical structure / organizational and human resource policies, with minor advances on labor policies, in much the result of the guiding focus of the reform on SEARH/RN. The impacts in total were more positive than negative and direct paths to improvement in public organizations. Making a general analysis of the modernization program implemented in SEARH/RN, we can conclude that there was a distinct change in all dimensions studied, mostly pointing out positive aspects, and contrary to the opinion of some authors, who claim to be very difficult to implement reforms in public organizations, since they are highly institutionalized environments. What was found was a big organization, with gaps and weaknesses, but with a much larger number of hits and recognition from institutional actors

Arraias em rios da região Sudeste do Brasil: locais de ocorrência e impactos sobre a população

INTRODUÇÃO: No presente trabalho objetivamos descrever o processo de colonização da Bacia do Alto Paraná, Sudeste do Brasil, por arraias, demonstrando sua atual situação e provável tendência, os impactos gerados e discutindo algumas ações de manejo e medidas mitigadoras. MÉTODOS: Foram realizadas entrevistas com ribeirinhos e profissionais de saúde para o levantamento de informações sobre a ocorrência de arraias e acidentes associados a estes animais, além de coletas e observações subaquáticas de potamotrigonídeos, entre 2004 e 2009, em localidades situadas nos Estados de São Paulo, Paraná e Mato Grosso do Sul, no Sudeste, Sul e parte do Centro-Oeste do Brasil. RESULTADOS: Três espécies de arraias foram identificadas na área de estudo, demonstrando utilizar os caminhos abertos pela Hidrovia Tietê-Paraná para se dispersarem. Dezesseis vítimas de acidentes envolvendo esses animais foram encontradas, notadamente banhistas e pescadores, chamando a atenção pelo fato dos casos não serem notificados e apresentarem elevada morbidade, com marcante incapacidade temporária para o trabalho. CONCLUSÕES: Este é o primeiro relato de invasão biológica envolvendo espécies de elasmobrânquios conhecido na literatura e, pelas arraias estarem colonizando áreas densamente povoadas e ampliando sua área de distribuição a cada ano, é de se esperar que sua interação negativa com humanos se intensifique, provocando alterações importantes no perfil epidemiológico dos acidentes por animais peçonhentos ocorridos no sudeste brasileiro.

A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais

The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed parallel to the coast, combined with coast engineering interventions. High energy hydrodynamic process are responsible for the morphological instability of the coast. The study was based on remote sensing data obtained between 1954 and 2007 which consist in orbital images from Landsat, CBERS and Ikonos satellites and aerial photos. With all data integrated on GIS environment it was possible to update thematic maps of geology, geomorphology, vegetation, soil and landuse and development of multitemporal maps pointing areas with erosion and depositions of sediments, defining the critical erosion process on this region. The bigger morphological changes are related to changes on wind patterns during the year, terrestrial and sea breezes during the day, with spits and barrier island migration, opening and closing of channels like the one parallel to the coast on the area of Serra and Macau oil fields. These factors combined with the significant reduction on sediment budgets due to the loss of natural spaces to sediment reworking contribute to the low resilience which tends to be growing on the area of Serra and Macau oil fields. In front of such scenery a detailed monitoring was done in order to find technological possibilities for coastal restoration. A pilot area was defined to start the project of mangrove restore together with beach nourishment in order to minimize the effect of the erosion caused by the channel parallel to the coast, contributing to stabilize the northeast channel as the main one. It s expected that such methodology will aid the coastal environments restoration and the balance between industrial activities and coastal erosion

Alterações no Código Florestal Brasileiro: impactos potenciais sobre a ictiofauna

É apresentada uma análise dos possíveis impactos que a diminuição da vegetação nativa, notadamente das florestas ripárias, pode causar sobre a ictiofauna. Três conjuntos de aspectos funcionais primordiais desempenhados pelas florestas ripárias são discutidos: transferência de energia solar ao ambiente aquático, interceptação de nutrientes e sedimentos que adentram nos rios e trocas de material orgânico entre o sistema terrestre e aquático. Conclui-se que qualquer alteração que se traduza em mais perdas de vegetação nativa, seja em áreas de preservação permanente ou em reservas legais, pode gerar perdas de espécies, homogeneização faunística e diminuição de biomassa íctica.

Vizinhança global ou proximidade imposta? Impactos da comunicação intercultural mediada por computador sobre o papel da cultura no ensino de língua inglesa

Muitas práticas educacionais no ensino e aprendizagem de línguas parecem ainda dominadas por uma visão de cultura essencialista, na qual os alunos, suas habilidades e atitudes de aprendizagem são caracterizadas por estereótipos problemáticos e/ou imaginários de suas culturas religiosas, étnicas e nacionais. As novas ferramentas e aplicativos para comunicação trazidos pela internet têm contribuído para o aumento de práticas comunicativas entre indivíduos de diferentes culturas e o uso da língua inglesa entre falantes não nativos, o que também tende a trazer impactos sobre a maneira como entendemos e ensinamos cultura na aprendizagem de tal língua. Este artigo pretende explicitar a visão de cultura presente nos conceitos de competência comunicativa e competência intercultural, e discutir a necessidade de reformulação do componente cultural no ensino e aprendizagem de línguas, para que ele objetive a exploração da complexidade advinda do pragmatismo dos encontros interculturais na contemporaneidade.

Aspectos e impactos ambientais de pedreira em área urbana

O conceito de desempenho ambiental tem sido utilizado como forma para revelar as relações da empresa com o meio ambiente e com a sociedade, constituindo um parâmetro de análise da sua postura diante das questões sócio-ambientais. A avaliação dos aspectos e impactos ambientais gerados por determinada atividade é um instrumento da gestão ambiental, sendo aplicado, nesse trabalho, em uma pedreira de diabásio, na área de expansão urbana, no município de Campinas (SP). Foram avaliados os aspectos e impactos das etapas produtivas da pedreira e de suas instalações administrativas. Os impactos adversos mais significativos levantados foram a sobrepressão atmosférica e a vibração do terreno, causando desconforto à comunidade. Após tais levantamentos, algumas ações de melhoria foram implantadas pela empresa e resultaram na diminuição das reclamações por parte da comunidade; outras medidas, pró-ativas, devem ainda ser implementadas, principalmente aquelas voltadas para a prevenção de impactos negativos e a preservação do meio ambiente, além da recuperação da área degradada, como medida reativa.

A Via Campesina Brasil e a avaliação da primeira década de impactos da reforma agrária do Banco Mundial

During the past decade, influenced strongly by World Bank land policies, many governments instituted a new mode of recreating the peasantry, one supposedly led by market forces through credit programs secured by land. Supported by large landowner organizations, defended as a conquest by the rural labor movement and combated by member organizations of the Via Campesina, the new mode of peasant renovation has inspired a diversity of interpretations both positive and negative. To evaluate these events, this article seeks to demonstrate the World Bank's intentionality in urging the implementation of market-led agrarian reform in developing countries; discusses the construction of immaterial territories in the context of this policy; analyzes the development of a people's think tank in response to the agitation of the Via Campesina Brazil and the negative impact of the credit system on peasants.
