Zoneamento geoambiental como subsídio ao planejamento territorial municipal: estudo de caso para Currais Novos/RN

This paper presents the master plan and geoenvironmental zoning natures as instruments of environmental planning and management. The discussion of territory environmental planning is guided by two directions: at first the environmental elements involved in planning and the another is the implementation of these instruments at the municipal territory. To analyze the planning directed of the municipal territory we consider the fragments of its, represented by country and urban. The master plan inside of the Estatuto da Cidade (City Statute) and the geoenvironmental zoning are directed to territorial environmental planning. Regarding of the master plan the first challenge has been the spacial area that the plan can cover. It is necessary to prepare master plans that could include all the territory. The environmental zoning are directed for the territory totality.In this sense, the geoenvironmental zoning of the Currais Novos was done in the totality of the municipal territory and guided by the environmental physics variables. The geoenvironmental zoning sets in a planning and ordering of the territory instrument based in the landscape analysis. Therefore grounded in the Geosystems‟s Theory this work has like a main objective to propose a geoenvironmental zoning for the Currais Novos Municipality in RN. So, was used an analysis technique suggested for Bardin (2010) and the Currais Novos‟s physical environment characterization through of the fieldwork and cartographic data vectorization, beyond the image‟s treatment SRTM. The geoenvironmental systems definitions were based in the suggestion of Cestaro, et al. (2007) support in Bertrand (1968). For both were identified five geoenvironmental systems: Borborema Plateau, Residual plateau, Chapada da Serra de Santana, semiarid river valley and lagoon valley and eleven geoenvironmental subsystems: Borborema Plateau Western Slope, Isolated Massif of the Borborema Plateau, Residual Crest, Residual Massif, Erosional Scarp of the Chapada, flat top plateau, fluvial plains, temporary river of the semiarid and ornamental water or sluice

Uso do GPR na geração de modelos estáticos 3D para o planejamento de lavra de minerais pesados depositados em dunas eólicas

This project was developed as a partnership between the Laboratory of Stratigraphical Analyses of the Geology Department of UFRN and the company Millennium Inorganic Chemicals Mineração Ltda. This company is located in the north end of the paraiban coast, in the municipal district of Mataraca. Millennium has as main prospected product, heavy minerals as ilmenita, rutilo and zircon presents in the sands of the dunes. These dunes are predominantly inactive, and overlap the superior portion of Barreiras Formation rocks. The mining happens with the use of a dredge that is emerged at an artificial lake on the dunes. This dredge removes sand dunes of the bottom lake (after it disassembles of the lake borders with water jets) and directs for the concentration plant, through piping where the minerals are then separate. The present work consisted in the acquisition external geometries of the dunes, where in the end a 3D Static Model could be set up of these sedimentary deposits with emphasis in the behavior of the structural top of Barreiras Formation rocks (inferior limit of the deposit). The knowledge of this surface is important in the phase of the plowing planning for the company, because a calculation mistake can do with that the dredge works too close of this limit, taking the risk that fragments can cause obstruction in the dredge generating a financial damage so much in the equipment repair as for the stopped days production. During the field stages (accomplished in 2006 and 2007) topographical techniques risings were used with Total Station and Geodesic GPS as well as shallow geophysical acquisitions with GPR (Ground Penetrating Radar). It was acquired almost 10,4km of topography and 10km of profiles GPR. The Geodesic GPS was used for the data geopositioning and topographical rising of a traverse line with 630m of extension in the stage of 2007. The GPR was shown a reliable method, ecologically clean, fast acquisition and with a low cost in relation to traditional methods as surveys. The main advantage of this equipment is obtain a continuous information to superior surface Barreiras Formation rocks. The static models 3D were elaborated starting from the obtained data being used two specific softwares for visualization 3D: GoCAD 2.0.8 and Datamine. The visualization 3D allows a better understanding of the Barreiras surface behavior as well as it makes possible the execution of several types of measurements, favoring like calculations and allowing that procedures used for mineral extraction is used with larger safety

Planejamento e ordenamento territorial do turismo na região metropolitana de Natal-RN

This work entitled "Planning and Tourism Territorial Management in the Metropolitan Region of Natal-RN" analyzes the tourism and its relationship to (re) production of socio-territorial inequalities in the metropolitan region of Natal (RMNatal) to from the planning and territorial management of the activity. For both, the methodological procedures were undertaken from research held about of literature on tourism, planning and territorial management, surveying and public policy analysis of tourism in national and local as well as the construction of levels of integration and differentiation of metropolitan municipalities in relation to tourism. Besides the shortage of studies on this subject, this research has shown that public policies focused on this sector has come under a great fragility in regard to tourism planning in Brazil and in Rio Grande do Norte, causing the planning activity is a strong array of fragmentation and socio-territorial inequalities in RMNatal

Faixas de proteção ambiental do Rio Pitimbu/RN: uma análise como subsídio ao planejamento e ordenamento do território

The Environmental Protection area sof Pitimbu river are important tools for planning and territorial land management. The Pitimbu river protection is aided in laws, so much of Federal stamp, as the Brazilian s Forest Code (Law No. 4771/1965), and in State s and City s Resolutions. So, this research begins in the State s Law No. 8426/2003interpretations, for being the most restrictive in the river's margin occupation and management. The objective is to analyze the applicability of the Environmental Protection areas of Pitimbu river, localized at the State of Rio Grande do Norte, considering environmental legislation and how to use this space by the man. Having specific goals for the discussion of the legislation s scope to this river; the identification of the types of soil s covering and evaluation the effectiveness of Law Nº.8426/2003, as protection instrument and land management. The river is characterized by its ecological importance and for feeding the Jiqui pond, an important reservoir that supplies 30% of drinking water to the east, west and south population sof the capital of the State. Pitimbu river is passing by a process of environmental degradation, originating from actions as deforestations of its ciliary forests by intensive agricultural practices; introduction of urban and industrial effluents leading to its contamination; increase of the pluvial drainage; erosion, sedimentation and discharge of urban waste , along with pressure for urban settlements along its banks. Under the methodological point of view is part of theoretical planning and land management research, and from a vision of social and environmental spaces. It was produced a survey map of the soil s covering, with 16 classes. Divided into coverage and disturbed natural covering. Using the 300 meters spatial limits of the Environmental Protection Strip, according to the State Law. The survey highlighted a higher percentage of classes disturbed, indicating man s interference in the balance of that system, as well as the lack of environmental actions. Leading to the degradation of riparian areas, and lack of conservation of water resources. Finally, it was considered that the strips of environmental protection are not effective as the preservation and territorial ordination

Princípios da construção enxuta no processo de planejamento de uma construtora de grande porte de Natal (RN)

Considered as one of the oldest activities done by men, the civil construction represents one of the most important sectors for the economic growth of a country, in spite of the low results of growth in the past few years and also in the current year. To make this industry grow, even with an unfavourable economic scenario, it is necessary to implement an effective planning in its activities. This is one of the most important concepts brought by the Lean Construction philosophy, which had its origin through the adaptation of the concepts established by the Toyota Production System (TPS) or Lean Production. By having as a scenario the city of Natal\RN, the main goal of this dissertation consists in investigating how the 11 principles of the lean construction influenced the schedule of a construction field that started to implement its lean concepts. As a methodology, it was used the case study of a big enterprise located in Natal (RN). During the execution of the method, documents related to the short-term, midterm and long-term planning were analysed , aiming to describe its planning process; it was also described the factors that caused the delays at the enterprises’ field ;in addition, a comparison was made between the results obtained at the case study and the ones presented at the literature; in the end, the actions were listed by the company, which had the purpose to solve the main causes of delays, verifying if they were linked to the lean construction principles. This research finds its reason of existence in the relevance of its theme at the nowadays reality of the construction industry, since the principles of the lean construction uphold the reduction of processes that are useless, diminishing wastes as well as costs in construction. The relevance is perceived for the academy, in terms of the possibility to discuss if the concepts established by the lean production are being adapted to the civil construction sector and how this adaptation is influencing at the buildings planning project. Economic importance, because with the reduction of the wastes and costs, the companies may reduce the building´s value into a more accessible value, even with the sector´s lower growth. And social significance, because lean construction gives a better participation of the labour at the planning activity. Among the main results, the high frequency of planning errors stands out, mainly the programming deviations and not the task programming, as well as the execution errors, low productivity and activities executed by the workers. Amongst the 11 principles of lean construction, only five were related with the 12 actions analysed by the author. From the 12 actions, four were completely cohesive to one or more from these five principles. Some improvement proposals were also highlighted and established by the research.
