Avaliação do impacto socioambiental de indústrias têxteis no rio Jundiaí - Macaíba/RN/Brasil

The contamination of aquatic environments is a phenomenon that dates back the origins of human civilizations and was amplified by the advent of industrial processes. The Jundiaí river , Macaíba's main water source, suffering discharge of effluents from various industries. The study work´s in two fronts, the environmental perception front was conducted through semistructured interviews whose textile effluent was appointed by the population as the main problem in the river. It was observed that nearly all respondents had concerns about the environment. In addition, there is an inclusion of individuals as the cause of the problem, because a significant part recognizes that its activities may cause damage to the environment and people's health. In other front, the experimental monitoring of water quality was conducted through ecotoxicological tests and physiochemical analysis that proposed to assess Pomacea lineata .Mysidopsis juniae isolated effect of textile effluent and its influence on the river compared with the limits established by Brazilian law. Although the physio-chemical analysis shows is inconclusive about the participation of the textile effluent in environmental contamination of the river, the ecotoxicological tests have shown to blunt the signal that the effluent may present a risk to aquatic organisms and consequently to human health. Thus, an interdisciplinary way it was possible to study the cause of the environmental problem identified by the population in the realization phase and measurable effect on water quality analysis in the river by means of the tests mentioned.

Implicações socioambientais da construção de um parque eólico no município de Rio de Fogo-RN

The purpose of this study was to investigate the social-environmental implications of the first large scale wind farm recently built in Brazil (2006), Parque Eólico de Rio do Fogo (PERF), to the nearby communities. The research was base on the adjustment of the DIS/BCN tool to analyze social impact and it was linked to the multi-method approach. Applying the autophotography strategy, cameras were given to five children from the district of Zumbi, the nearest location to PERF, and they were asked to individually photograph the six places they liked the most and the six places they liked the least in their community. Then, these children were interviewed individually and collectively about the photographs. Adult locals in Zumbi, residents of Zumbi/Rio do Fogo settlement, members of the State and Municipal government and representatives of the PERF were also interviewed with the aid of some of the pictures taken by the children and others that might trigger something to say, as a strategy called sample function. The five children presented positive image towards PERF; all of them chose to photograph it as one of places they liked. Adult population of Zumbi presented positive visual evaluation towards PERF. A small number of the interviewees were aware of the environmental and social benefits of wind energy production. Residents did not participate of the decision making process regarding PERF. They approved the project, especially because of the jobs provided during construction. Nowadays, PERF is something apart from their lives because it no longer provides jobs or any other interaction between the facility and the locals. Residents relate to the land, not with the facility. However, there is no evidence of rejection towards PERF, it is simply seen as something neutral to their lives. The low levels of education, traditional lack of social commitment and citizenship, and the experience accumulated by PERF´s planners and builders in other countries, may be contributing points to the fact that Zumbi residents did not oppose to PERF. It is clear that the country needs a legislation which seriously considers the psycho-social dimension involved in the implementation of wind farms

Análise da problemática socioambiental de nascentes urbanas no município de Garanhuns-PE

Garanhuns City, in Pernambuco, undergoes a rapid, polluting and non-organized urban development affecting its freshwater springs around the urban environment. These sources are of great importance to the district as well as to the hydrographic basin of the Mundaú River. In this view, this paper aims at analyzing the socio-environmental problems resulting from the urban expansion surrounding the Garanhuns’ sources. The study considers the social and environmental dynamics and follows the theoretical contributions of socio-environmental geography proposed by Mendonça’s Urban Environmental System methodological and theoretical model (2004), as well as the conceptual values of Santos’ space theory (2002a). The data treatment included bibliographical and documental research, evaluation of environmental impact, and water analysis. It revealed that Garanhuns possesses many local environmental traits favoring the coming out of freshwater springs and that these sources have played an important role in the making and development of that village. The environmental impacts on freshwater springs, like Olho D’água, Bom Pastor, Vila Maria, Pau Amarelo and Pau Pombo have been evaluated through the environmental impact score IIAN. It put alight serious cases of socio-environmental impacts on the dynamics of the freshwater springs. In the period of April 2013 and April 2014, it monitored the superficial water quality expelled by the Pau Pombo, Pau Amarelo e Vila Maria water sources, and the analyses of the contents followed the determinations of the Environmental National Board, whose parameters are dissolved oxygen, biochemical demand of oxygen, nitrate, total coliforms, faecal coliforms, and electrical conductivity. The results recollected suggest the existence of organic pollution and deep alteration in the water coming out from the sources. In consequence, it seems important the putting out of measures destined to stop those impacts and guaranteeing protection and maintenance of the freshwater springs and their micro-basins.
