The average rates of coastline variation are one of the best indicators to determine the trend of the oscillatory behavior of any part of the coastline over time. The multi-temporal study of the coastline dynamics of the beach segments of Mosqueiro Island, PA, using the Landsat and Sentinel series of satellite imagery, the United States Geological Survey (USGS) and the European Space Agency (ESA) with the aid of the Digital Shoreline Analysis System (DSAS), demonstrated that during the period from 2001 to 2018, the total linear mean change for all beach segments was -81.3 m at a rate of -9.67 m / year. The average linear retreat was - 160.77 m, while the average linear advance was 79.47 m, indicating a clear erosion tendency of the Mosqueiro Island coast. From the 11 beach segments analyzed (Baia do Sol, Paraíso, Marahú, Carananduba, São Francisco, Ariramba, Murubira, Porto Arthur, Bishop / Praia Grande, Bitar), in the western part of the Island, 06 (São Francisco, Ariramba, Murubira, Porto Arthur, Bishop / Praia Grande and Bitar) showed a trend of retreat of their coastlines, presenting average rates of variation from -1.00 m / year to -3.31 m / year, the highest rate belonging to the Bishop segment /Big beach. The segments of Baía do Sol, Paraíso, Marahú, Carananduba and Farol / Chapéu Virado were the only ones that presented a tendency to advance in their coastlines, presenting values of average rates varying from 0.30 m / year to 1.74 m / year. In addition to the study of the behavior of the coastline of the western part of Mosqueiro Island, the classification of the physical vulnerability to the coastal erosion of the Island was carried out. In general, the coastal zones of the island bathed by Guajará Bay, Furo das Marinhas and Furo do Maguari were classified as "high to very high", with the exception of some sectors located in the northwest, northeast and southeast of the island. were classified as "low to moderate" vulnerability. The most localized areas in the center of the island not directly impacted by oceanographic variables were classified as "very low to moderate"vulnerability, in addition to some contiguous areas that were classified as "high" vulnerability.

O direito fundamental ao meio ambiente do trabalho equilibrado em face da monetarização dos riscos: a análise do caso dos trabalhadores do Projeto Salobo desenvolvido no Sudeste do Pará
(Universidade Federal do Pará, 2017-04-28) VIEIRA, Lucas Rodrigues; NASSAR, Rosita de Nazaré Sidrim; http://lattes.cnpq.br/2092928958819725
The present dissertation deals with the problems related to the ineffectiveness of the fundamental right to the environment of work, especially due to the adoption of a purely monetarizing policy of risks that is only concerned with financially compensating workers for exposure to agents harmful to their life and health, As verified in the labor demands related to the Salobo Project developed in the Southeast of Pará. Thus, the main objective of the work is to verify the legal instruments that can be used to promote a healthy labor habitat for employees, as a way of protecting physical integrity and consequently reduce the rates of industrial accidents and occupational diseases, to the detriment of discussions restricted to the imposition of additional remuneration (additional to insalubrity and dangerousness) that do not serve to encourage the adoption of medical norms and security job. For this, the dissertation carried out a survey of the doctrine and the national and international legal order, as well as qualitatively analyzed four judicial processes of the Salobo Project judged by the Regional Labor Court (TRT) of the 8th Region in the last two years. The work was constructed in three chapters. The first chapter addressed the definition, characteristics, and functions of fundamental law norms, based on the thoughts of Robert Alexy. Subsequently, historical, conceptual and legal aspects related to the work environment. The second chapter discussed the formation of the risk society, according to Ulrich Beck's theory. After that, the main risks arising from the work activity were discussed and the policy of mere monetization of environmental risks at work was discussed. Finally, the third chapter examined the working conditions of workers in the Salobo project developed in Southeastern Pará, based on lawsuits that were processed in the TRT of the 8th Region, and pointed out the alternatives to the realization of the fundamental right to the environment of balanced work. In conclusion, the research verified that the workers of the mentioned project were exposed to risks to their well-being, but only monetizing instruments were used that do not alter the conditions of the working environment, not making use of preventive and precautionary measures, such as, for example, inhibitory tutelages combined with temporary emergency orders.

Percepção de risco e vulnerabilidade social dos moradores de Ajuruteua.
(Universidade Federal do Pará, 2018-07-04) OLIVEIRA, Ubiranilson Santos de; PIMENTEL, Márcia Aparecida da Silva; http://lattes.cnpq.br/3994635795557609
This study investigates the perception of risk and social vulnerability of the residents of Ajuruteua, a beach located 36 km from the town of Bragança-Pará. Part of this area is considered as a very high risk to marine coastal erosion, as noted by the destruction of properties located by the sea. Erosion is a natural event that affects people’s safety and it is triggered by anthropic factors, especially by disorderly occupation. Due to this the government proposes the evacuation of people from risk areas, because they are vulnerable to erosive action. However, it comes across the economic factor of the families involved, since the income of the people living there depends on the fishing, commerce, houses rental, hostels and other activities developed in the coast. In this perspective, this research aimed to verify residents’ perception on the risk of erosion, as well as to record their adaptation to natural events, and to monitor the impacts of removing the vulnerable population from risk areas to the municipality's headquarters. Such a context brings out the following issues: Can the understanding of the risk perception and social vulnerabilities of people living in Ajuruteua contribute to public policies for disaster risk reduction? The methodology was based on theory and method literature review, documentary research in public and private institutions and the application of a script of interviews with local residents and entrepreneurs. The objective of the interviews was to understand and identify the degree of social vulnerability of the resident population in Ajuruteua from the population 's perception of natural erosion events. It is hoped that the study will be able to contribute to public policies for disaster reduction, collaborating with the discussion about the different perceptions about the appropriate use of natural resources available in Ajuruteua.
