Abstract: Fire severity is defined
as the degree of fire intensity and its impact on the ecosystem. The
objective was to carry out bibliometric, scientometric and informametric analyzes of the
international production on the spectral indices used in the analysis of the severity of fires, wi th
the purpose of identifying the tendency of production, in addition to classifying and quantifying
the severity of fires in the Environmental Protection Area of Headwaters of the Cuiabá River
(APACRC), through the normalized spectral burn index (NBR) and its variations. For the survey
of bibliographical productions, the Scopus database was used. A global search was carried out
(internationally and without spatial coverage) of articles present in this database that contained,
in the title, abstract or keyw ords, the descriptors vegetation, severity, index and burn or fire. The
period of production related to the theme was from 1997 to 2021, with 374 scientific articles
published in 127 journals. In the journal impact analysis, it was identified that, among t he
journals, only a few had a significant impact. As for the ranking of the most cited countries, it is
possible to observe the United States, in first place, with 10,377 citations and an average of 65.26
citations per article. In second place is Spain, wi th 2,354 citations and an average of 48.04
citations per article. Brazil, on the other hand, is in the 25th position, with 11 citations and an
average of 5.5 citations per article. For the analysis of the burned area in the Conservation Unit
(UC), pre fire scenes (before the occurrence of the burning, dated September 05, 2020) and post
fire scenes (after/during the occurrence of the burning, dated on September 18, 2020). The
criterion for choosing the images if the fire occurred in the year 2020. In order t o identify the
degree of severity of the referred burning episode, the NBR indices and the normalized and
relativized burning index (dNBR) were calculated for pre and post burning. The normalized
difference vegetation index (NDVI) was also used to correla te the efficiency of the index
regarding its use in the application of the severity of burns. Among the formations that comprise
the study area, 18,870.57 hectares were affected by fire, with 87.51% composed of savannah
formation, 11.78% of forest formatio n and 0.71% of grassland formation, the most affected part
suffered low fire severity. To compare the effectiveness of the NDVI in the approach to fires, it
was necessary to submit the data relating them to the information presented by the NBR classes.
For this, the pixels of the relativized normalized difference vegetation index (dNDVI) were
superimposed on the dNBR classes and submitted to the statistical treatment of the Tukey Test. It
was concluded that, when comparing the means of dNDVI correlated to t he dNBR classes, a
significant difference was observed in all areas studied, with the exception of environments where
Moderate High Severity occurs when compared to High Severity. In all vegetation formations
studied, the dNBR index showed that, despite it s impact on the progress of burning, almost 100%
of the areas suffered low severity, leading to the conclusion that the negative impact on the regeneration of the affected area may not be very significant in this episode of burning. On the
other hand, the NDVI index proved not to be effective in identifying burned areas, when compared
to the NBR. However, it can be a guide to characterize the differences between the severity
classes.

Abstract: The Chapada dos Veadeiros National Park (PNCV) is considered by Unesco (United Nations Educational, Scientific, and Cultural Organization) a Natural World Heritage Site and the core area of the Savanna Biosphere Reserve. It is one of Brazil's Hotspots, with its phytophysiognomies entirely within the Savanna domain. Established in 1961, by President Juscelino Kubitschek, under the name Parque Nacional do Tocantins, it had an area of approximately 625 thousand hectares, which was successively reduced. On May 11, 1972, the park was given its boundaries of 171,924 hectares, based on diagnoses made by a commission of the Ministry of Agriculture. Nine years later, in 1981, the PNCV lost part of its territory, being restricted to 65 thousand hectares, because of the "Alto Paraíso Agricultural Project", presented by the Government of Goiás, requesting, at the time, the passage of the GO-239 highway between Morro da Baleia and Morro do Bração. In 2001, it was recognized as a Natural Heritage Site of Humanity by UNESCO, having its area increased to 235,000 hectares. However, the expansion decree was suspended in 2003 by the Federal Supreme Court, due to flaws in the public consultation process, returning to the area defined in 1981. With a new decree of June 17, 2017, it had its area expanded to 240,586.56 hectares (PM,2019). The Pouso Alto Environmental Protection (APA) Area was created by Decree No. 5.419, of May 7, 2001, it is a Pouso Alto Environmental Protection Area, intended to foster sustainable development and preserve the flora, fauna, springs, geology and landscaping of the Pouso Alto region, located, in the Chapada dos Veadeiros National Park, in this State (GOIÁS, 2001).The overall objective of this dissertation is to understand how the process of land use and land cover, environmental fragility and vulnerability occurred in the area of the PNCV: since the process of creation (1961); the area reductions (1972 and 1981); and the process of expansion, (2001 and 2017). This work is integrated in the PNCV area, with mapping for analysis of landscape geoecology, vulnerability and environmental fragility. The modeling results indicated that, in relation to the potential fragility, what predominates is the Medium class with 61.50%, with the area of approximately 147.992,22 hectares, and the Emergent fragility with the Low class, with 85.1% with an area of 204.616,97 hectares. In relation to environmental vulnerability, what predominates is the medium class with an area of 198.902,07, with a percentage of 82.56%. Despite the geomorphology and soil types of the region presenting high fragility or vulnerability, the conditions of preservation of the Savanna in the region, reflects in the stability of the landscapes.

Abstract: This work presents the peasant communities of Salgado and Pedra Lisa, inserted among the 21 regions of the municipality of Quirinópolis, with the origin of their family nucleus by the pioneers of the region, period of the genesis of Quirinópolis, when it was still a district of Rio Verde. For decades, a local peasant identity was generated, with family farming and well-being with nature, however, such characteristics were re-signified with the passing of the stages of agricultural development in the Brazilian Midwest. In view of this, a survey of the historical agricultural context of the Midwest region was carried out, as well as the specific context of Quirinópolis, directly impacted by the monocultures of soy and the recent sugar cane, aiming to present the communities, having all the basis of their rural history, and how it resignified with the capitalist advance in the countryside. For the good development of the research, a wide bibliographic base was used, to have the theoretical basis of the agricultural development process, as well as local authors, making it possible to deepen the knowledge of the peasant communities, specifically those of Salgado and Pedra Lisa, from the research empirical with interviews and photographic documentation, presenting them from their inception to the present day. After the research, it was observed that, through agricultural mechanization, and the recent sugarcane monoculture, these communities were strongly transformed, their roots metamorphosed and their current situation surrounded by capitalist advancement. Pioneer practices fell into disuse with the modernization of the countryside, but peasant production remains the main source of income for families, mainly due to the contributions of cooperatives, which enabled peasants to compete in the local market with the production of milk and vegetables.

Abstract: The Administrative Region of Planaltina is considered the only urban center in the Federal District
that pre-existed the construction of Brasilia, the current capital of Brazil, annexed at the end of
the 20th century to its lands and which previously belonged to the territory of Goias. The history
of this location was marked by the apogee, but mainly by the decadence of the post-mining period
in Minas Gerais and its surroundings, and by the agricultural activity of the Central West. The
memories of this historic city are recorded in its big house, streets, squares, celebrations, and
festivities over almost two centuries, thus producing diverse cultural landscapes and
transformations in the sociospatial relations of the Traditional Sector of Planaltina. The general
objective of this dissertation is to understand from the geographical point of view, the Traditional
Sector of Planaltina, demonstrating the sense of place present in its historical, property, and
cultural aspects. The present study follows a qualitative approach focusing on direct observation
and analysis of photographic records, secondary data, and theoretical reference. The research
follows as a proposal for mostly linear case studies, and to achieve its objectives, goals are set
that make up theoretical, technical, and cartographic procedures, a survey of theoretical and
documentary references, from the choice of historic buildings and patrimonialism assets, passing
through fieldwork and simple observations, mapping and spatialization of the analysis and
evaluation and discussion of data on patrimonialization. These studies are important for the
periodization of a place, as well as the rescue of cultural and historical memory, and become basic
instruments for the formulation of territorial management plans and diagnoses of the impacts
caused by the transformation of the cultural landscape itself, without forgetting to mention in the
analysis of unrevealed contradictions beyond the city-heritage context. Among the nearly 4,000
buildings belonging to the architectural-urban complex of the Traditional Sector of Planaltina, 21
buildings that pre-existed the construction of Brasilia deserved individual listing and protection
by the local government. These buildings were selected for inventory due to their historical and
cultural relevance and thus make up the case study. Twelve of these buildings are located in the
preservation and conservation polygon proposed by the district legislation, and the other nine are
located in the surroundings of the state's heritage area. In the field, progress was made in the
process of alteration and de-characterization of some properties, which compromises not only the
preservation but also the conservation of these assets. The Traditional Sector of Planaltina plunges
into a process of de-characterization and ruination of its past landscape; we are talking about a
historical and cultural erasure. The properties, blocks, squares, streets, and avenues now listed by
local decrees do not guarantee their preservati on and conservation, as well as in the areas where
they are located.
