ABSTRACT This paper presents a case study related to the environmental impacts of urban sprawl in areas of environmental protection. The objective was to analyze the environmental changes caused in the Environmental Protection Area of Puraquequara - AM. The study was conducted in the neighborhood of Puraquequara in 5 communities (Bela Vista, John Paul, St. Francis Maina, Coast Tabocal and Vila do Puaraquequara). To collect the data was used as the case study method, with the application of semi-structured interviews technique to facilitate the creation of an open, where the interviewee is expressed freely. In total 30 families were interviewed, and only one person per household was interviewed. Then was also a questionnaire containing the following: 1 - socioeconomic, 2 - environmental and 3 - protected and development area. In general, the results obtained in this study indicated the presence of different factors, such as lack of knowledge and information of the residents in relation to the conservation of natural resources in the study area. It was observed that the respondents, 100% is considered important Puraquequara the Environmental Protection Area for communities, however, only 10% of respondents have knowledge about the contents of the legislation governing the sustainable use conservation units. We conclude that because the urban and population growth, there are several environmental problems, mainly caused by the changes in the landscape and the reduction of vegetation cover or pollution and \ or siltation of streams. Therefore, from the results obtained in this study, we suggest the implementation of programs for reforestation and environmental education of residents of the APA, so that all are aware of the importance of preservation and conservation of natural resources in the area. Keywords: Ecosystem. Protected Areas. Environment.

The present work is to study the conceptions about the importance of preservation and conservation of water resources in springs. The work was carried in the agricultural community of Rufino sub-station in Cologne Agricultural João Paulo, located in the neighborhood of Puraquequara - Manaus. The objective was to diagnose from surveys of environmental problems the possible consequences of changes in the springs caused by various factors in the environment. The information and data collections occurred during the entire year of 2014. For the development of research used as methodological procedures the bibliographic survey available on the area of study. Among the techniques used for data collection is on-site visits and also the use of camera to record environmental impacts on springs. Were identified four sources, classified into two categories: spring in good state of preservation - those that had vegetation cover and absence of environmental impact factors and degraded spring - one where the vegetation was absent and where there is the presence of environmental degradation factors. For residents of Agricultural Colony community João Paulo the spring water serve for various activities, such as the supply of dams for fish farming as the tambaqui (Colossoma macropomum), matrixa (Brycon sp) and pirarucu (Arapaima gigas) serve also for irrigation of plantations in family farming. In spring degraded the results showed silting surrounding the spring and streams; the absence of vegetation and fauna; soil discharge and changes in water quality and quantity. It follows that the impacts caused by the activities surrounding the springs caused an ecological imbalance. To reduce such damage monitoring of springs is necessary, thus avoiding the various types of pollution in the dynamics of nature. So with the information obtained in this study, we suggest the development of new work on the study area, with the implementation of programs focused on reforestation and regeneration of water resources management.
