Article Synopsis
- * The study analyzed data from 2001 to 2022 to assess vegetation recovery post-fires and identified priority conservation areas based on fire intensity, using advanced algorithms to detect fire foci, precipitation, and carbon flux.
- * Findings showed a total of 300,127 fire foci during the study, with 2020 facing the worst conditions due to low precipitation, while years with high rainfall, like 2014 and 2018, correlated with higher GPP values, suggesting a strong relationship between these environmental factors.
Article Synopsis
- The study examines how different land use and land cover (LULC) in the southern Brazilian Amazon—such as native forest, pasture, and crop fields (rice and soybean)—affect soil fertility and texture.
- It aims to inform farmers for better land management practices that enhance sustainable agriculture while considering the environmental impacts of expanding agricultural areas.
- Statistical analyses, including PCA and geostatistical methods, reveal important soil characteristics that vary with LULC, helping to predict soil attributes effectively for different agricultural uses.
In recent years, Brazil has become a major global contributor to the occurrence of national fires and greenhouse gas emissions. Therefore, this study aimed to evaluate the fire foci data of the past 20 years to determine their relationship with climatic variables in various Brazilian regions. The variables evaluated included fire foci, land surface temperature, rainfall, and standardized precipitation index, which were obtained via remote sensing from 2000 to 2019.

- - The study aimed to track the increase of soybean farming in the Amazon biome of Mato Grosso, particularly focusing on violations of the Soy Moratorium from 2008 to 2019 using remote sensing data from two monitoring programs.
- - A total of 1,387,288 hectares were deforested according to the PRODES data, with 108,411 hectares (7.81%) converted into soybean fields, while the ImazonGeo data reported 729,204 hectares deforested, with 46,182 hectares (6.33%) converted.
- - Specific municipalities like Feliz Natal, Tabaporã, Nova Ubiratã, and União do Sul showed higher soybean expansion contrary to the Soy Moratorium, with
Application of remote sensing in environmental impact assessment: a case study of dam rupture in Brumadinho, Minas Gerais, Brazil.
Environ Monit Assess
August 2021
The collapse of mining tailing dams in Brumadinho, Minas Gerais, Brazil, that occurred in 2019 was one of the worst environmental and social disasters witnessed in the country. In this sense, monitoring any impacted areas both before and after the disaster is crucial to understand the actual scenario and problems of disaster management and environmental impact assessment. In order to find answers to that problem, the aim of this study was to identify and analyze the spatiality of the impacted area by rupture of the tailing dam of the Córrego do Feijão mine in Brumadinho, Minas Gerais, by using orbital remote sensing.

Fire foci across the country contributes to these emissions and compromises emission reduction targets pledged by Brazil under the Paris Agreement. In this paper, we quantify fire foci, burned areas, and carbon emissions in all Brazilian biomes (i.
