The present work had the objective of mapping the Cuinarana river basin and describing the state of conservation of the sources in the municipality of Magalhães Barata, northern Pará, through an environmental diagnosis of the headwaters and cartographic production of thematic maps, in order to subsidize actions to promote the maintenance and sustainable use of water resources. It should be noted that there is no information of this nature for the studied municipality and therefore the area was chosen for the study, as a way of detecting the environmental problems in this basin, in order to develop public policies directed to environmental education.The study identified the situations of degradation of the main springs, in addition to georeferencing the Cuinarana River. The procedures adopted for the elaboration of the environmental diagnosis of the headwaters were based on evaluation protocols, which emphasize the physical integrity of the habitat around the headwaters, observing the aspects of the use and occupation of the soil, predominant vegetation, characteristic of the springs, its uses and the state of conservation. For the river maps, the boundary of the Cuinarana River basin was based on georeferenced relief data from the area in question, derived from the dot matrix products of the Shuttle Radar Topography Mission (SRTM), prepared by the US government agency National Aeronautics and Space Admistration ( NASA), and provided with correction calculations by the National Institute of Space Research (INPE), Brazil. The results obtained demonstrated that of the 11 springs raised, three 3 are in poor condition due to environmental impacts. The information from the maps shows that the Cuinarana River basin has undergone a process of transformation due to anthropic interference, resulting in different socio-environmental problems unaccompanied by effective environmental planning policies. Faced with the problem, the research product is a didactic atlas of the Cuinarana River Hydrographic Basin, composed of 10 thematic maps.

Proposta de monitoramento ambiental do parque estadual do Utinga: uma ferramenta para a melhoria dos serviços prestado a população da região metropolitana de Belém

This work was developed in order to present an Instruction Guide, as a subsidy to the conception of the environmental monitoring system proposed for the State Park of Utinga (PEUt), which it was decided to call SISPEUt. In order to make it simpler and, therefore, more likely to be implemented, it was first decided to idealize it for the qualitative investigation of the soil and water in the Park. Initially, a study was carried out to verify the recommendations regarding the installation of a monitoring system for the environmental quality of the PEUt. This stage included the analysis of Brazilian hydro-environmental laws, norms, plans and programs that directly or indirectly presented such recommendations. Next, a survey of the vulnerability of the area was carried out in the face of the advance of the urbanization of the RMB. In this investigation, the threats imposed on the Park and its environmental elements became evident. In order to reveal details about the advantages of an environmental monitoring system, a study of qualitative and quantitative monitoring cases in protected areas in Brazil and abroad was carried out. The results showed benefits for the entire production chain associated with the monitored area, with gains also for the management bodies, for the political, academic and scientific classes, as well as for the general population. From all the survey carried out, the hypothetical-deductive method was used to ratify the objective of this work, which is summarized in presenting the Guide mentioned above. The architecture adopted for the proposed system was guided by the policies and guidelines of the ePING (Electronic Government Interoperability Standards), which advocates the use of public and/or free computer programs in the design of monitoring systems such as SISPEUt. The parameters to be monitored were defined according to norms and hydro-environmental programs in force or in progress in Brazil, with the contribution of systems that monitor environmental variables in the national territory. As for the location of the measurement and sample collection points, these were determined based on the Park's physiography and the threats imposed on the Conservation Unit (UC). In short, the final product of this work is considered an important contribution to environmental management in the RMB, since the implementation of SISPEUt can bring important subsidies to the protection of the CU and, consequently, improve the services provided to the population, especially those related to the provision of water for public supply.
