“…Besides, Kumar et al (2016) suggest that 3% of atmospheric emissions at MASP are related to fuelwood burning by pizzerias. Another important factor is associated with land use and land cover in the region and the management of cultivated areas, especially in the interior of the São Paulo State ( Rudke et al, 2019 , 2021 ). Mostly in sugar cane plantations, the pre-harvest burning practiced has demonstrated a significant impact in increasing concentrations of pollutants associated with fires (e.g., smoke, inhalable particulate matter, and total suspended particulates) ( El Chami et al, 2020 ; Tsao et al, 2012 ; Uriarte et al, 2009 ).…”

Mobility restrictions are among actions to prevent the spread of the COVID-19 pandemic and have been pointed as reasons for improving air quality, especially in large cities. However, it is crucial to assess the impact of atmospheric conditions on air quality and air pollutant dispersion in the face of the potential variability of all sources. In this study, the impact of mobility restrictions on the air quality was analyzed for the most populous Brazilian State, São Paulo, severely impacted by COVID-19. Ground-based air quality data (PM 10 , PM 2.5 , CO, SO 2 , NO x , NO 2 , NO, and O 3 ) were used from 50 automatic air quality monitoring stations to evaluate the changes in concentrations before (January 01 - March 25) and during the partial quarantine (March 16 - June 30). Rainfall, fires, and daily cell phone mobility data were also used as supplementary information to the analyses. The Mann-Whitney U test was used to assess the heterogeneity of the air quality data during and before mobility restrictions. In general, the results demonstrated no substantial improvements in air quality for most of the pollutants when comparing before and during restrictions periods. Besides, when the analyzed period of 2020 is compared with the year 2019, there is no significant air quality improvement in the São Paulo State. However, special attention should be given to the Metropolitan Area of São Paulo (MASP), due to the vast population residing in this area and exposed to air pollution. The region reached an average decrease of 29% in CO, 28% in NO x , 40% in NO, 19% in SO 2 , 15% in PM 2.5 , and 8% in PM 10 concentrations during the mobility restrictions period compared to the same period in 2019. The only pollutant that showed an increase in concentration was ozone, with a 20% increase compared to 2019 during the mobility restrictions period. Before the mobility restrictions period, the region reached an average decrease of 30% in CO, 39% in NO x , 63% in NO, 12% in SO 2 , 23% in PM 2.5 , 18% in PM 10 , and 16% in O 3 concentrations when compared to the same period in 2019. On the other hand, Cubatão, a highly industrialized area, showed statistically significant increases above 20% for most monitored pollutants in both periods of 2020 compared to 2019. This study reinforces that the main driving force of pollutant concentration variability is the dynamics of the atmosphere at its various time scales. An abnormal rainy season, with above average rainfall before the restrictions and below average after it, generated a scenario in which the probable significant reductions in emissions did not substantially affect the concentration of pollutants.

“…It also produces changes in atmospheric temperature due to the emission of greenhouse gases. From another perspective, it also generates alterations to the hydrological cycle (Legesse et al, 2003;Li et al, 2007;Rudke et al, 2019). The change in land use through the monoculture of exotic species is contributing both to the loss of habitat and biodiversity and the species extinction (Fierro et al, 2016).…”

“…In this sense, various satellite products have emerged in recent years for the entire globe, which increases the available mappings (Grekousis et al, 2015). Several authors have studied and compared different global mapping products on land use and have concluded that they have discrepancies in terms of results and databases, consequently, several products have been developed at regional level (Capucim et al, 2015;Congalton et al, 2014;Congalton, 1991;Herold et al, 2008;Rudke et al, 2019).…”

“…Image processing was performed on the free QGIS 3.8.2 software developed by the OSGeo foundation, using the Semi-Automatic Classification Plugin (SCP; Leroux et al, 2018). For each class, 50 samples were collected using high-resolution imaging (Google Earth), following Rudke et al (2019). Figure 2 presents the flowchart of the classification process: Figure 2: Flowchart of the Landsat satellite image classification process for both the years 1999 and 2019.…”

Abstract. The use of satellite images is a modern strategy for the evaluation and prediction of various weather scenarios. In addition, this is a key tool for the development of environmental sciences. Since the end of the last decade, Chile has been suffering from a megadrought associated with climate change. In this context, this study proposes to evaluate the role of land use change in the Middle Maule River sub-basin, located in the Maule Region, Chile. This is an important sector characterized by a significant agricultural and hydroelectric contribution. To do so, this study performs a supervised classification of land cover through the usage of QGIS software and Landsat images for the years 1999 and 2019. The results show the growth of areas without vegetation due to a great drought facing the Central Zone of the country. Additionally, there is a decrease in available bodies of water. This article leaves open future research on the impact of the main economic activities of the region.

“…Mapeamentos oficiais produzidos pelo governo brasileiro, do projeto TerraClass Cerrado, mostraram em 2013 um remanescente de apenas 54% da vegetação natural total do bioma Cerrado (BRASIL, 2015). Dentro da BHPR, da qual o bioma Cerrado anteriormente ocupava quase a metade da área, apenas 5% da cobertura original permanecia em 2015 (RUDKE et al, 2019). Segundo o monitoramento do projeto PRODES Cerrado do INPE, entre 2001 e 2020 ocorreu a supressão de mais de 290 mil km² da vegetação nativa do Cerrado (INPE, 2021).…”

Em primeiro lugar, não poderia deixar de agradecer a Deus pela conclusão de mais essa etapa em minha vida. Durante a pandemia, além da força e persistência, Ele me concedeu saúde, elemento mais valorizado e necessário.Agradeço a toda minha família, pelo apoio que nunca faltou, em especial à minha mãe Neide, meu padrasto Douglas e minha irmã Alyne. O caminho nunca foi solitário. Nesse período em que nem a segurança de tê-los bem existiu, conseguimos fazer da 'presença distante' nossa casa. Em memória da querida tia Áurea, primeira acadêmica da família, sempre atenta à conclusão do meu doutorado. Espero minimamente corresponder às suas expectativas.Agradeço também à minha companheira de vida Ana Paula, pela alegria nos dias bons e paciência nos dias difíceis. Agradeço de forma sincera ao meu orientador, professor Dr. Edmilson, pela confiança, apoio e formação profissional e pessoal exemplar. Quero seguir meu caminho com ao menos um pouquinho do seu desejo e coragem para melhorar as coisas ao redor.Ao professor Dr. Jorge Martins, pela ajuda no projeto de pesquisa e ingresso no programa de doutorado.
