Amazônia ameaçada: análise do discurso jornalístico nos portais de notícias O Liberal.com – PA e A Crítica – AM sobre desmatamento e queimadas no contexto da pandemia da COVID-19

The year 2020 was marked by the beginning of the COVID-19 pandemic and the increase in deforestation and fires in Brazilian Amazon. Data from Inpe (2020) recorded 10,312, 88 km2 of consolidated deforestation in the region, in addition to 103,161 outbreaks of fires during that year. Months of August and September were the ones with the highest rate of fires and the states of Pará, Mato Grosso and Amazonas accounted for 70% of deforestation. Meanwhile, "the herd passed" [a figure of speech refering to Ricardo Salles speech] with the approval of 593 acts by the federal government related to changes in rules on environmental protection in Brazil (OBSERVATÓRIO DO CLIMA, 2021). Amid the health, political and environmental crisis, journalism played an important role in providing information to population (CASERO-RIPOLLÉS, 2020). In this context, this research analyzes how was the coverage on deforestation and burning in two of the main news portals of the North region of the country: “O Liberal.com – PA” and “A Crítica – AM”, during the month of September 2020, considering the pandemic period and its adversities. The main theoretical and methodological framework chosen was the Critical Discourse Analysis - CDA (FAIRCLOUGH, 2001). Through the analysis of the newspapers it can be concluded that Jair Bolsonaro government, in the midst of the COVID-19 pandemic, managed to occupy a privileged space in the publications, with a speech aimed at alleviating the problems in the Amazon and widely reproduced by the two newspapers without significant counterpoints. Justifications that attributed deforestation and burning to the climate itself in Amazon and to agricultural activities traditionally carried out by rural, indigenous and quilombola communities were used. In addition, the credibility of scientific data on the subject disclosed by institutions such as the National Institute for Space Research - INPE was questioned.

Análise de correlação de focos de queimadas com variáveis climáticas no município de Marabá
(Universidade Federal do Pará, 2016-03-10) ARANHA, Priscila Siqueira; FRANCÊS, Carlos Renato Lisboa; http://lattes.cnpq.br/7458287841862567
The Amazon is composed of a wide variety of ecosystems and forms of occupation, taking a wide variety of settings, including spatial, social, economic, agronomic, which vary from region to region. From this perception of the Amazon region, this work presents an investigative study scenarios and their correlations, in order to quantify and qualify the strength of relationships and dependencies between the different variables involved, such as meteorological factors (relative humidity, rainfall, speed wind and temperature) and the number of fire outbreaks, in order to enable the analysis of the reasons that influence the environmental degradation of the study area. In order to validate the proposed methodology, we conducted a study in the city of Maraba area of settlement projects, whose focus is to analyze the correlation between climate variables and fire outbreaks in the region, using three study scenarios. Therefore, we use some statistical parameters, the Pearson correlation and Bayesian networks in order to establish the degree of dependency between the different variables of interest. From such studies, it is possible to make a set of inferences about the problem under study and possible alternatives, which more balance scenarios for the benefit of environmental sustainability.

Proposta de distribuição de hidrantes urbanos no município de Ananindeua-PA utilizando Sistemas de Informações Geográficas
(Universidade Federal do Pará, 2023-01-27) FERNANDES NETO, Antenor Amaral; ADAM, Katiúcia Nascimento; http://lattes.cnpq.br/2498018628901734; ALMEIDA, Aline Christian Pimentel; http://lattes.cnpq.br/1388841813412015; https://orcid.org/0000-0002-7421-5632
This work analyzed the physical conditions and the distribution of urban fire hydrants in the city of Ananindeua-PA, using GIS tools and how this distribution impacts the fire protection of the municipality. For this, four steps were carried out: In the first stage, the rules and norms in force on urban fire hydrants where surveyed. In the second stage, data were collected from existing hydrants (quantification, verification of installation and maintenance conditions, use and distribution of hydrants), through field visits and collection of secondary data from competent authorities (COSANPA and Firefighters). Subsequently, an analysis of the installation and maintenance conditions of urban fire hydrants was carried out using geoprocessing techniques. Finally, after analyzing the data, a proposal was drawn up for the redistribution of this equipment in the urban area of Ananindeua-PA (technical report), with the aim of optimizing the use and making fire fighting more effective. Thus, it was possible to verify the divergence between the current norms, as well as the inadequate distribution of urban hydrants and their poor maintenance, in addition to showing lower flow rates than required by the norms.

Relação entre diâmetro do caule e espessura da casca das árvores amazônicas e sua implicação na resistência ao fogo
(Universidade Federal do Pará, 2024-03-28) GAMA, Valter Thiago Pantoja da; FERREIRA, Joice Nunes; http://lattes.cnpq.br/1679725851734904; https://orcid.org/0000-0002-4008-2341; BARLOW, Bernard Josiah; http://lattes.cnpq.br/8559847571278134
The characteristics of plants are important for understanding their functions and relationships with the environment and the functioning of ecosystems. Tropical forests, such as the Amazon, are important for promoting ecosystem services that are important for maintaining biodiversity and human well-being. However, these forests are facing major threats due to human interference, especially climate change and forest fires. Therefore, given this scenario, research focused on forest resistance to disturbance regimes can help in the monitoring and conservation processes of this type of biome. Therefore, the aim of this study was to evaluate the relationship between stem diameter at breast height (DBH) and bark thickness in tropical Amazonian forests, in order to identify the significance of the relationship between these variables and the possible effects on the degree of forest resistance to fire. The study was carried out using forest inventory data from 21 plots in the Lower Tapajós, in the Eastern Amazon - PA. In order to assess the relationship between DBH and bark thickness, data from 11 botanical families was used in a GLMM (Generalized Linear Mixed Effect Models). The relationship between the variables was significant, with an overall explanatory power of 34% for DBH over thickness, and considering the variation between botanical families, this power increased to 50%. Our results show that of the 11 botanical families studied, only half have trees with bark thick enough to be considered resistant (17-23 mm). In addition, in order to consider trees with or without resistance potential, we analyzed bark thickness at a minimum DBH of 10 cm and the increase in bark thickness as DBH increased. Fabaceae, Lecythidaceae and Burseraceae stood out as being more prone to fire mortality. Therefore, considering the high distribution of individuals belonging to these families in the Amazon and the current scenario of forest degradation, ecological impacts and climate change, this work raises insights into the Amazon's forest vulnerability to burning regimes, and the importance of its conservation for climatic conditions on a local and global scale.
