Abstract:
The uncontrolled use of fire has resulted in innumerable occurrences of forest fires in the Western Amazon, causing damage to the environment and society, verifying its association with the effects of corruption, since it deals with the selfish behaviors of some involved actors, aiming the well-being of a minority. This study is a case study that focuses on forest fires and their relationship with corrupt practices and Theory U. It brings as its objective general study of the relationship of corruption to forest fires in the Western Amazon; and have as specific objectives to raise the causal relationship of corruption in face of the denial of Theory U (1), to characterize the factors that involve the questions of the fires in the Western Amazon (2), and to offer efficient subsidies to impact the fires considering the attitudinal convergence of the Amazon (3). As a result, there is a denial of Theory U in the face of the selfish conduct of individuals who cause forest fires, since they are limited to the imprisonment of satisfaction of isolated wills, without seeking to emerge a future with greater social inclusion. The subsidies pointed out in this study allow us to verify the need for effectiveness in the inspection and control actions regarding forest fires by public entities related to the environment. It is up to civil society since everyone is harmed in this process, to self-organize and demand more effective measures from environmental managers.

Abstract:
ABSTRACT Wildland fires can be responsible for negative impacts on the environment, causing damage to the fauna and flora and increasing the release of greenhouse gases. In the state of Amazonas, wildland fires represent a risk for biodiversity conservation, since more than 95% of the state is covered by Amazon rainforest, one of the largest and most biodiverse tropical forests of the world. This study aimed to analyze the spatiotemporal variation of fire occurrence from 2003 to 2016 in the state of Amazonas, based on data from the AQUA satellite processed by the Brazilian National Institute for Space Research, using the “Collection 5” detection algorithm. The correlation between fire incidence versus anthropogenic and climatic variables was also tested. A significant uptrend was observed in the number of hot spots recorded over the years. About 83% of the wildland fires occurred during the months of August, September and October. The variables that correlated significantly with the number of hot spots for each municipality were deforested area, pasture area, agricultural area, municipality area and mean annual rainfall. The municipality with the highest number of hot spots detected was Lábrea, while Careiro da Várzea presented the highest incidence per km2. The southern and eastern regions of the state were the areas most affected by fire during the analyzed period. The results from this study emphasize the need for implementation of public policies aimed to reduce deforestation and wildland fires in the state, thus ensuring the conservation of the Amazon rainforest and its biodiversity.

Abstract:
Fires such as those that occurred in 2019 in the Amazon are examples of the intensification of these events in recent years and contradict the claim that forest fires only reach great proportions in years of extreme drought. This is a worrying scenario, as the Amazon Rainforest plays an important role in regional and global climate regulation. This study therefore sought to identify the methodologies used to describe and predict fire events in the Brazilian Amazon. For this, a systematic literature review was carried out in the open access databases Scientific Electronic Library Online (SciELO) and Directory of Open Access Journals (DOAJ) using the descriptors “fire risk” and “Amazon”, and their variants in the Portuguese language and the logical operator “AND” in the search. From the resulting search materia we identified the use of predictive models based on projections for climate change developed by the Intergovernmental Panel on Climate Change (IPCC), which indicate a substantial increase in the probability of fires. Another technique used is the crossing of heat foci data with the forms of land use, evidencing the areas that burn the most and when, as well as the most susceptible areas. There were also studies analyzing the performance of fire risk indexes, demonstrating those that could be used after adaptations to local characteristics. These results allow an understanding of the behavior of fire in the Amazon, since they provide a broad view of how studies on fires have been conducted and what techniques have been used.

Abstract:
This study uses a combined research approach based on remote-sensing and numerical modeling to quantify the effects of burned areas on the surface climate in the two Brazilian biomes most affected by fires: the tropical savanna and the Amazon rainforest. Our estimates indicate that between 2007 and 2020, approximately 6% of the savanna and 2% of the rainforest were burned on average. Non-parametric regressions based on 14-year climate model simulations indicate that latent heat flux decreases on average by approximately 0.17 W m−2 in the savanna and 0.60 W m−2 in the rainforest per each 1 km2 burned, with most of the impacts registered during the onset of the wet season. Sensible and ground heat fluxes are also impacted but at less intensity. Surface air is also warmer and drier, especially over rainforest burned sites. On average, fire reduced gross primary production in the savanna and rainforest by 12% and 10%, respectively, in our experiments.

Abstract:
Abstract. Amazon forest dieback is seen as a potential tipping point under climate change. These concerns are partly based on an early coupled climate–carbon cycle simulation that produced unusually strong drying and warming in Amazonia. In contrast, the fifth-generation Earth system models (Phase 5 of the Coupled Model Intercomparison Project, CMIP5) produced few examples of Amazon dieback under climate change. Here we examine results from seven sixth-generation models (Phase 6 of the Coupled Model Intercomparison Project, CMIP6), which include interactive vegetation carbon and in some cases interactive forest fires. Although these models typically project increases in area-mean forest carbon across Amazonia under CO2-induced climate change, five of the seven models also produce abrupt reductions in vegetation carbon, which indicate localised dieback events. The northern South America (NSA) region, which contains most of the rainforest, is especially vulnerable in the models. These dieback events, some of which are mediated by fire, are preceded by an increase in the amplitude of the seasonal cycle in near-surface temperature, which is consistent with more extreme dry seasons. Based on the ensemble mean of the detected dieback events we estimate that 7±5 % of the NSA region will experience abrupt downward shifts in vegetation carbon for every degree of global warming past 1.5 ∘C.

Abstract:
Illegal selective logging and forest fires occur on a large scale in the northern Brazilian Amazon, contributing to an increase in tree mortality and a reduction in forest carbon stock. A total of 120 plots of 0.25 ha (30 ha) were installed in transitional ecosystems or ecotones (LOt) between the forested shade-loving campinarana (Ld) and dense-canopy rainforest, submontane (Ds), in the National Forest (Flona) of Anauá, southern Roraima. Measuring the diameters at breast height (DBH ≥ 10 cm) and the heights of 171 dead trees (fallen naturally, illegally exploited, and affected by forest fires), enabled the estimation of carbon content from the application of a biomass equation developed at Manaus, and the calculation of a correction factor, using the average height of the largest trees. From 2015–2017, we mapped the real extent of illegal selective logging and forest fires across the region with CLASlite and INPE/Queimadas. From measurements of 14,730 live and dead trees across 30 hectares (491 ± 15 trees·ha−1), the illegal selective logging and associated forest fires, and aggravation by severe El Niño droughts resulted in an 8.2% mortality of trees (40 ± 9 dead trees·ha−1) and a 3.5% reduction in forest carbon stock (6 ± 3 Mg·ha−1) in the short-term. The surface area or influence of forest fires of very high density were estimated in the south-central region of Roraima (8374 km²) and the eastern region of the Flona Anauá (37 km²). Illegal selective logging and forest fires in forest areas totaled 357 km² in the mosaic area, and 6 km² within Flona Anaua. Illegal selective logging and forest fires in the years of severe El Niño droughts threatened the maintenance of environmental services provided by Amazonian forests.

Abstract:
The Amazon rainforest has been the target of several attacks, such as the massive increase in deforestation and fire outbreaks. The Amazon biome is not only composed of forest ecosystems, but also of an important carbon stock system called Peatland, which contains ca. 1 to 8 billion tons of carbon in its plants and soil. If burned, this peculiar ecosystem is likely to release tons of greenhouse gases, which may aggravate global warming. Therefore, our objective is to alert and anticipate problems associated with deforestation and fires in Peatland that, if not contained, may difficult global warming controlling, and the achievement of goals set in the Paris Agreement (which Brazil is a signatory).

Abstract:
Devastating forest fires in Brazil’s Amazon rainforest, one of the most important biomes for Earth’s climate balance, have captured the world’s attention in 2019 and 2020. Foreign governments, non-governmental organizations, and institutional investors pressured Brazilian President Jair Bolsonaro to act and control the situation. Within this context, institutional investors threatened to divest from companies potentially linked to the wildfires and to sell government bonds, creating a divestment movement. Against this background, this article shows that Bolsonaro’s responses varied for each of the groups criticizing the handling of the environmental situation. It is argued that the Brazilian government adopted a more conciliatory tone and took more concrete actions when responding to institutional investors’ demands, compared to the responses for foreign governments and non-governmental organizations (NGOs). Based on fifteen in-depth interviews conducted in 2021 with professionals involved in this divestment case, the paper concludes that institutional investors played a key role in Bolsonaro’s winning coalition and electoral aspirations. Moreover, the shortage of financial capital due to the COVID-19 pandemic created further incentives for Bolsonaro to avoid conflicts with institutional investors.

Abstract:
Burns are common practices in Brazil and cause major fires, especially in the Legal Amazon. This study evaluated the dynamics of the fire foci in the Legal Amazon in Brazil and their consequences on environmental degradation, particularly in the transformation of the forest into pasture, in livestock and agriculture areas, mining activities and urbanization. The fire foci data were obtained from the reference satellites of the BDQueimadas of the CPTEC/INPE for the period June 1998–May 2022. The data obtained were subjected to descriptive and exploratory statistical analysis, followed by a comparison with the PRODES data during 2004–2021, the DETER data (2016–2019) and the ENSO phases during the ONI index for the study area. Biophysical parameters were used in the assessment of environmental degradation. The results showed that El Niño’s years of activity and the years of extreme droughts (2005, 2010 and 2015) stand out with respect to significant increase in fire foci. Moreover, the significant numbers of fire foci indices during August, September, October and November were recorded as 23.28%, 30.91%, 15.64% and 10.34%, respectively, and these were even more intensified by the El Niño episodes. Biophysical parameters maps showed the variability of the fire foci, mainly in the south and west part of the Amazon basin referring to the Arc of Deforestation. Similarly, the states of Mato Grosso, Pará and Amazonas had the highest alerts from PRODES and DETER, and in the case of DETER, primarily mining and deforestation (94.3%) increased the environmental degradation. The use of burns for agriculture and livestock, followed by mining and wood extraction, caused the degradation of the Amazon biome.

Abstract:
This study seeks to explain political leaders' motives to action, by studying how Jair Bolsonaro and Emmanuel Macron have acted in the matter of the fires in the Amazon rainforest. It is assumed that while political leaders may try to act rationally, they are influenced by psychological factors in terms of educational background and style. The theories of rational choice and political psychology are therefore used and integrated to explain their motives. The method used in the paper is a comparative qualitative content analysis, in which various statements and speeches made by the Presidents are read and analyzed. The results of the thesis show that for Bolsonaro, the Amazon fires is an internal matter and should be handled by the Amazonian countries. He seems to be seeking to achieve national goals, while being influenced by his conservative educational background. Macron indicates that the Amazon is an issue for the international community and that it is of major importance for the whole world. He appears to be seeking international goals, while being influenced by his liberal educational background. The assumption that political leaders' style influence their motives to action is not supported.

Cette étude examine l'énonciation polyphonique dans les écrits en ligne, en se focalisant sur celle issue et induite par les interactions sur YouTube lors des feux de forêt en Amazonie. Après une présentation du contexte et des concepts et théories liés à la polyphonie, elle propose un ensemble méthodologique d’analyse de la polyphonie qui permet de saisir d’abord la place des aspects techno-sémiotiques, socioéconomiques, et psychosociologiques de YouTube dans la polyphonie, puis d’interroger cette polyphonie au niveau des autres acteurs médiatiques cités à partir de YouTube. Nous arrivons ainsi à identifier des constances et des changements de configurations polyphoniques au cours de notre période d'observation et à montrer comment ces configurations polyphoniques pendant les feux de forêt d’Amazonie pouvaient être influencées par des variables contextuelles exogènes. Nous constatons aussi des enjeux de pouvoir quand cette polyphonie est utilisée comme stratégie par différents acteurs impliqués dans la controverse sociale autour des feux de forêt d'Amazonie. Cette étude vient compléter les travaux sur l’énonciation éditoriale dans les écrits d’écran en prenant en compte la polyphonie tant au niveau des acteurs en réseau que celle au niveau de l’argumentation
This study examines polyphonic enunciation in online writings, focusing on that which arises from and is induced by interactions on YouTube during the Amazon rainforest wildfires. After presenting the context and the concepts and theories related to polyphony, it proposes a methodological framework for analyzing polyphony that first captures the role of techno-semiotic, socio-economic, and psychosociological aspects of YouTube in polyphony, and then interrogates this polyphony at the level of other media actors mentioned from YouTube. This allows us to identify consistencies and changes in polyphonic configurations during our observation period and to show how these polyphonic configurations during the Amazon rainforest wildfires could be influenced by exogenous contextual variables. We also observe power dynamics when this polyphony is used as a strategy by various media actors involved in the social controversy surrounding the Amazon rainforest wildfires. This study complements previous research on editorial enunciation in screen writings by considering polyphony at both the network actors’ level and the argumentation level

Full text
Abstract:
The Amazon basin is the largest tropical rainforest in the world covering almost 40 per cent of the South American continent. For centuries, its vastness and inaccessibility have been protecting this area. The general belief is that the Amazonia region has unparalleled biodiversity which means that one in five of all bird species known in the globe lives in the Amazon Jungle. The author is testing this claim against the known occurrence of the world owl species. There are fewer owl species in Amazonia than expected namely 34 (against 54 expected). Two possible reasons are that our knowledge of the Amazon region species is still incomplete as may be indicated that new owl species have been found recently. The other reason could be that the rainforest is not after all the most wanted biotope for many of the owl species which often depend on the prey available in the bottom tier of the forest which is flooded during the wet season. Whatever the reason is, more detailed research is needed on all species of the Amazon region as there must be many new owls and other animal species out there waiting to be discovered. We have no idea how many of those new species have been or will be lost due to the rainforest destruction before they can be discovered. Therefore, it is necessary to stop deforestation in the Amazonia, be it due to forest logging, uncontrolled fires (often deliberately set) agriculture expansion or industrial development. Deforestation is not the only reason that the Amazon basin is changing. The rainforest suffers also from the global climate change when the higher temperatures reduce the rainfall in the tropical Atlantic region, causing drought and increasing the fire susceptibility of the rainforest. Luckily the owls are not so sensitive to surrounding forest cover as many other tropical forest-dependent bird species, like the large-bodied avian frugivores. Impacts of forest fragmentation on owls will need additional research.

Full text
Abstract:
The seed bank is directly related to forest resilience because it contributes to the greatest number of regenerants after the occurrence of disturbances. Changes in seed density, floristic composition, and life forms completely alter the successional trajectory of forest environments. These changes are directly related to land use. For example, suppression of the seed bank can occur in pastures, that experience frequent fires with increase of density of seeds and predominance of herbs are typical of highly degraded areas, such as Poaceae, Rubiaceae, Asteraceae, and Cyperaceae. Melastomataceae seedlings are an important component of the seed bank in the Amazon rainforest. On the other hand, Urticaceae has greater representation in forests that exhibit low-impact land use. Any change in seed bank functionality is bound to compromise the diversity, regeneration potential and overall maintenance of tropical forests. Therefore, it is necessary to expand studies that investigate seed banks in the Amazon rainforest. It is as important to prioritize sampling methods and pursue standardization of data presentation, as well as improve the identification of species that occur in the seed bank.

Abstract:
Wildfires are not natural phenomena of the Amazon rainforest; therefore, they occur due to human activities, and their occurrences have increased in recent years. This situation requires continuous monitoring of this vast region, especially in areas where agricultural, livestock, mining, and infrastructure activities are located near protected areas (indigenous lands and nature conservation units). One of the conservation units that has recorded the highest increases in deforestation and fire rates is the Triunfo do Xingu Environmental Protection Area (APA Triunfo do Xingu), which since 2018 has registered the highest rates among other conservation units in the Amazon. The present study aims to develop two databases of burned areas from optical and microwave images for the years 2018, 2019, and 2020 for the APA Triunfo do Xingu using Google Earth Engine; then the results are compared with the DETER, MAPBIOMAS and MCD64A1 burned area bases to estimate existing similarities and divergences. This research uses the images of the Sentinel-2/S-2 and Landsat-8/L-8 optical satellites for the month of August of the years 2018, 2019, and 2020, a period of increased occurrences of active fires in the APA Triunfo do Xingu, to generate the burned area database that will serve as a reference for comparison with other burned area databases. Thus, images with spatial resolution, S-2 with 10 meters and L-8 with 30 meters and spectral (red, near, and medium infrared bands), are suitable for generating information with geometric and thematic quality, as the GEE allows the production of pixel mosaics excluding pixels with cloud and cloud shadows. The Sentinel-1/S-1 images used correspond to the VH cross-polarization, which is the most suitable polarization to map burned area than the VV polarization (Prasasti et al., 2020), having 10 meters of spatial resolution, being with speckle noise filter and with backscatter (DB) values. It is noteworthy that the S-1 images correspond to Band C, the wavelength of 5 cm, which reduces the interference of clouds when imaging the surface. In general, the BA-S1, BA-DETER, BA-MAPBIOMAS, and BA-MCD64A1 datasets obtained discrepant values concerning the reference dataset, which reveals that a consolidated base with values consistent with the reality of the fire regime of the study area is still to be achieved, as the discrepancies found reveal that the data and methodologies followed are not generating consistent quantitative information. Regarding the overlaps between the datasets, the spatial similarity between the datasets have a higher rate with polygons above 20 hectares, which allowed an average overlap of 63%, 69%, and 78% for the BA-S1, BA-MAPBIOMAS, and BA-MCD64A1. The BA-DETER dataset was below 20%, as it presents the lowest values of the number of polygons for the three years.
