The present work aimed at investigating the small hotel managers perceptions from Natal/RN concerning the environmental practice uses as a competitive factor. This study is characterized as a descriptive exploratory research that used an aleatory probabilistic sample followed by the application of collect data instrument (questionnaire). The small hotels located in Natal/RN were the study participants and the specific location where 35 questionnaires were answered. Based on the data and on the mangers point of view, it is possible to comprehend that, among the presented indicators, the development of environmental programs in the hotel enterprise is showed as the least important for the client s choice. As the main conclusion it is relevant to argue that, according to the small hotel managers, the guests do not still search for hotels that implement environmental practices. On the other side, the interviewed managers believe that the use of these practices can generate a great competitive advantage in relation to their competitors. The information obtained by this present research will be able to contribute to establish a contemporary panorama in relation to the importance attributed by the managers concerning the use of environmental practices in small hotel enterprises in Natal/RN. In addition the correct use of this information can generate possibilities of major competitiveness in this segment

The existence of several negative indicators such as deforestation, pollution of rivers and urban growth disorderly suggest a scenario of serious environmental degradation in Brazil, allowing that the model of public management of the environment here is not practiced efficiently, despite to be a recognition-of environmental legislation as one of the best and most comprehensive in the world. One of the main causes of this problem is the low social participation in environmental management that often exists only in the formal plan. Thus, although defined as Democratic State, in practice, it is only a Figurative State. Based on the study of the origin of the state and social participation in the Brazilian State, in general scope, and some environment committees and public hearings in Rio Grande do Norte, as instruments of social control, in particular scope, it is possible to build a real Democratic State in environmental management, a Participative State, in which all players are aware of the responsibility and committed to the duty assigned to them by the constitutional text with the present and future generations

Given the prediction of the Federal Constitution of 1988 about the need to establish some areas to be especially protected, it was published the Law No. 9.985/00, which established the National System of Conservation Units. Several aspects make these units differ from one another, one of them being the possibility of presence of even traditional human populations inside the area to be protected. In case of allowing these people to continue in the area, it still must be provided their participation in the management of the new space. Management councils show up, then, as a specific way of social and political participation. This way, from an overview of legal norms and the doctrine that are relevant to the topic, It is aimed to make a legal and theoretical survey about the process of traditional populations permanence inside Conservation Units, with aspects linked to ethnoconservation and, therefore, to participation in environmental management of these specially protected spaces

Blooms negatively compromise the aquatic environment, plants, animals and human health.Some species are toxin-producing, such as the neurotoxin saxitoxin and the hepatotoxin microcystin, which may contaminate water reservoirs, as those existing in the semiarid region of Rio Grande do Norte (Brazil) which are used to supply the population, fishing, aquiculture and recreational activities, thereby providing the risk of human exposure through water intake, dermal contact and respiratory tract. Thus, it is recommended a constant monitoring of the density of cyanobacteria with the quantification of cyanotoxins. One goal with this work was the monitoring of water in four reservoirs in semiarid of RN through the identification and enumeration of cyanobacteria and through the identification and quantification of cyanotoxins by ELISA. Furthermore, we intended to assess the environmental perception of farmers and artisanal fishers in reservoirs of semiarid of RN through semi-structured interviews with questions mostly related to water and eutrophication. Through these objectives the aim was the development of management strategies for aquaculture and prevention of risks to public health. The results showed that the highest values of microcystins were found in the rainy season. Standards for drinking water, according to the guidelines of Ministry of Health 2914/2011 and CONAMA 357/05, setting the maximum values for raw water density of cyanobacteria: 50,000 cel.mL-1; microcystin: 1 μg. L-1 and saxitoxin: 3 μg. L-1. The values found for microcystin ranged between 0.00227 μg. L-1 and 24.1954 μg. L-1. From 128 samples analyzed, 27% were above the limit. There was no clear seasonal pattern for saxitoxins and their values ranged between 0.003 μg. L-1 and 0.766 μg. L-1 with none of the values above the limit. Furthermore, 76% of the densities of cyanobacteria values were above the limit. About environmental perception, 52 interviews were conducted and the results show that the respondents recognize the main uses of water of the rervoirs, recognize the importance and have a positive view about the reservoirs. They also realize that the water has a poor quality and can cause health problems. The results provide data showing the persistence of cyanobacteria and cyanotoxins, many times over the limit, reinforcing the importance of constant monitoring. The assessment of environmental perception gives foundation for later proposed environmental education linked to public health management into the context of this particular population, making it more effective

This research presents a reflection on the dropout rates in higher education courses available through distance education in a context marked by deep changes in various spheres of society and by the uncontrolled growth of this educational method. For this, the object of analysis is related to the reality of students of Technology in Environmental Management offered by the Instituto Federal de Educação, Ciência e Tecnologia, Rio Grande do Norte (RN), Brazil, through the distance education in presence support poles located in Mossoró (RN) and Martins (RN). In this field research development several strategies of data collection are used, such as participant observation of reality; analysis of documents related to distance education and to the classes in Technology in Environmental Management; questionnaires answered by students who dropped the course. The results of such research enable us to say that the dropout rates in distance higher education is mainly referred to the consequences of a combination of aspects involved in the course development, personal difficulties faced by students during the period they attend the lessons and elements inherent in the context in which the course and students are inserted. Nevertheless there are specific situations in which the student may drop the program due to the influence of a single aspect, whether it is inherent in the development of the course, a personal situation, or even a factor determined by the context in which the course or the student belongs to

Surveys carried out in many Brazilian cities have shown that the CDW Construction and Demolition Waste, in some cases, represent more than 50% of the mass of urban solid residue. Municipalities have struggled to manage in an effective way huge quantities of CDW generated every day and solve the problem of the illegal dumping in an inadequate area, which compromise the quality of life of the population as a whole, thus causing serious problems concerning social-environmental and sanitary. This paperwork was meant it carry out environmental diagnosis of the management and the final destination of the CDW in the city of Parnamirim/RN. The methodology used in this work constituted in the bibliographical research, conducted to give support and fundaments to the subject in question, identification of the main places of legal and illegal dumping, identification of the environmental impacts caused by the irregular deposition of the CDW, valuation of quantity and quality of the CDW and perception according to the Environmental Legislation. The necessary data for the elaboration of this study were carried out through the appliance of questionnaires with open and closed questions, applied to 14 (fourteen) Real Estate developer companies associated with SINDUSCON/RN and 05 companies that deal with the transportation and collection of CDW, formal and informal interviews, exploitational visits and photographical records. The collected data went through a statistic treatment being organized into tables and graphs. The main results obtained from this research show that the interviewees hold a medium knowledge of the specific Environmental Legislation; do not have an effective model of environmental management, resorting to only reusing CDW; that the reusing of CDW is not substantial, as much as the possibility of recycling has a minimal consideration. It was also verified that a considerable percentage of interviewees affirmed to send CDW to illegal and inadequate locations. It is expected that such study can be used as an important tool to subsidize the public administration in the pursuit of solutions which could bring benefits to society and the environment

The present study inserts on the international environmental thematic, approaching the integrated management of solid waste and the participation of the social actors in the search of the sustainable development. The awareness in combining it still describes a Selective Collection Program SCP of solid waste, in partnership with the municipal public power, in the development of joint actions that result in better alternatives of waste management in the urban centers, providing better life quality for the population and conservation of the environment. The aim of this research is to study problematic of the management of solid waste under the point of view of the environmental awareness and the participation of the population in a city of Brazil. In this matter, the target of the work is focusing on the strategy of solid waste management, through the attitudes and the respondents behaviors to aid in the making decision of the public manager related to the implantation of a selective collection program in Natal/RN. The methodology used in this work constitutes in the application of a questionnaire with scales of the type Likert being constituted of variables that compose the aspects of attitudes and of behaviors, besides a social-demographic scale. For analysis statistics is used the Pearson s Chi-Square Method in order to verify the dependence of the associations between the social-demographic variables and the attitude and the behavior ones. The results appear for a larger participation in a SCP, since this provides a better quality of life of the population (28,3 %), followed for offering a financial advantage (27,3%). Other results indicate the existence of the variables that exercise influence on the environmental awareness of the population to its demographic aspects

Currently, many companies pay attention to the necessities of change of attitude in relation to the use of the natural resources and the environment quality of its products, mainly to keep a positive and competitive image in the market. This new concept of management associates the productive activities to the care with environment using the education of environment as a tool of programs of qualification directed toward the promotion of pro-environment behaviors. For effectiveness of this management it is essential the attachment of the employees and the major understanding of the importance of the preservation of the environment. This was the objective of the qualification process carried out in a lodge in Fernando de Noronha island. The purpose of this study, therefore, was to verify the power of this management system which fulfills the objectives of the environmental education. It was applied questionnaires to employees of three Inns and carried out a interview, in one Inn, with the participants of the program of qualification. The analysis of the data showed that the actions as care with the environment are strongly associates to the management system, which includes garbage control, as well water economy. It was observed that the environment accomplishment (EcoAntro) of the employees with environment decreases in proportion to their qualification. In the same way, as higher the instruction level, of the speaker and/or of the father, less is the apathy for environmental questions. It was also noticed that the knowledge about the development sustainability was very poorly used by the interviewed. The pro-environment behavior mentioned before, is not necessarily related to a local autonomy posture that could express a behavior related to job but not to environment it self. Therefore, a complete understanding about the reverberation of environment information an all the placed factors in a life stile facing a construction of sustainability remains as a question to be studied in future researches

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

The search for sustainable solutions through an appropriate environmental administration of the available natural resources, that comes from encounter to the aspirations of preservation of the environment and of the human being, in way to diagnose and to solve the environmental and social problems with the smallest possible impact to the nature and the man, it is the great challenge, so much for that generation, as for the future generations. The study of the environmental problems of the water and the participation and the social actors' environmental understanding as a whole, interferes in the field of the thematic environmental international, contemplating the strategic need of an appropriate administration of that very natural one, through a program returned to the diagnosis of the problems and in the search of compatible maintainable solutions, in a social and environmental politics of planning and environmental education, centered above all in the citizen's voice , user of that system. The present thesis she seeks to study the problem of the maintainable administration of the water, focusing the participation and the citizen's environmental understanding in the use of that very natural one for urban residential activities, in what concerns the approach and analyses of variables that treat of the measurement of general knowledge and you adapt, sense of community of the access to the means of information and of the attitudes and environmental behaviors, besides the variables of partner-demographic characterization or personal identification of the interviewed ones of an exploratory research of the type " survey ", accomplished through a stratified aleatory sampling, being the strata each one of the 4 (four) Political-Administrative Areas of the Natal city, having happened the collection of the data in the period of february to april/2002. The methodology used in this work it constitutes in the application of questionnaires with scales of the type Likert to measure the echo-varied of the study, besides a partner-demographic scale for the characterization of the studied sample. For the analysis of the results, it was made an exploratory descriptive study initially, followed by the use of techniques statistical multivariate s, such as, factorial analysis through the application of main components, besides the accomplishment of studies of multiple lineal regression. To complement this study, the accomplishment of Tests of Independence was proceeded through the Qui-square of Pearson, in way to verify the dependence of the associations between the partner-demographic variables and the principal selected variables and presents in the resulting factors of the factorial analysis. The results appear for a low level of environmental knowledge, of access to the information and community's sense, besides the verification that the principal factors resultants send for the need of feeling emphasis in the programs and administration actions addressed for the environmental understanding, the behaviors and attitudes that approach the information and the environmental education, besides the reuse of the water

This dissertation addresses issues considered essential for sustainable development of urban waterfronts and beaches. Many of these spaces, even though they are of public authorities, economic market and general population interests - due to its landscape, its importance for recreation purposes and as a basis of " Sun and beach Tourism " (Turismo de Sol e Praia), among other factors - have shown aesthetic, health and cultural degradation, entailing environmental, economic and social losses and conflicts. Based on this perception, the research aims to understand the main reasons for these negative results for beach spaces. To this end, it was chosen the case study of a typical urban beach, Ponta Negra Beach, located in Natal, RN. Ponta Negra is associated with the "postcard" of the city and it has been deserving of municipal urban planning legislation that legally recognizes the importance of its landscape. Also it has received constant investments by the Government through urban projects, arguing to leave the site attractive to its users. Nevertheless, in the last fifteen years, the beach has lived with the expansion of its problems, such as those related to bathing water, to coastal erosion, and to the mangling of its natural surroundings. Social conflicts have also been frequent in this time frame: conflicts between residents of the waterfront and traders who work on the beach, between the traders themselves, between the managers of space and fishermen, between managers and formal and informal traders. Many of these social and environmental conflicts have taken such grand proportions that became legal matters. Assuming that the problems identified are related to the issue of rationality - understood as a system of values, norms and actions that relate means and ends - and upholding the need for focused research on "environmental rationality" to understand and interpret the dynamics of social and environmental problems encountered on site, the research that guides the study relies on the Mexican economist Enrique Leff's theory on "environmental rationality" which, briefly, can be defined as a system of values, norms, actions and means and ends relations based on the principles of environmental management and sustainable development. Among other aspects, rationality encompasses cross-sectional planning of public administration, the participation of society in the management of environmental resources, interdisciplinary reorganization of knowledge, the clash of opposing interests and the conciliation of common goals of different social actors. The study evaluates the relationship between "environmental rationality", as proposed by Enrique Leff, with the management, urban interventions and uses observed in Ponta Negra Beach. For that, some benchmarks were established and considered in the research as related to sustainable development of the "beachy" atmosphere. Analytical instruments chosen were the urban transformations and the environmental and social problems that have been the target of lawsuits. Also part of the study, the problems that were the subject of civil investigations, which are investigation procedures carried out by the Prosecutor's Office.
