“…Studies such as Nobre (2014) and Rufino (2020), show the great relevance of this biome in regulating the climate on the continent. As Pantanal, the Amazon has also been suffering from the increase in deforestation and fires rates that have become more frequent, which are directly related to the process of deforestation, management of agricultural and livestock areas (Aragão et al, 2016;Arima et al, 2016;Copertino et al, 2019;Fuchs, 2020).…”

Particles of soot from forest fires are transported by the wind, reaching distant locations and being deposited on the soil through precipitation, which clears the atmosphere, taking suspended particulate matter into its drops. The general circulation over South America indicates the possibility of soot from forest fires in the Amazon and Pantanal to be transported to southern Brazil. The event called “black rain” was observed in the period from 11 to 13 September 2020 at São Francisco de Assis City, in Rio Grande do Sul State (RS), and so this work aims to analyze if there were any anomalies of the flow that favored the occurrence of this event, given that there was a large number of fires in this period. Through ERA5 reanalysis data and GOES-16 satellite images, it was observed that on the three days under study low-level flow to the south of Brazil was more intense than normal, with the Low Level Jet occurrences, and on days 12 and 13 such flow to the south was also observed at 500 hPa. The precipitation was due to the instability of an extended trough from the Northwestern Argentinean Low. Thus, it is believed that there was a contribution from circulation at low and mid levels in the occurrence of black rain over RS.

Growing population and rising incomes are leading to an ever-increasing demand for animal-based foods. Pigmeat is currently the most consumed meat globally, even exceeding the consumption of poultry meat. Despite the disproportionate environmental burden of animal production – mostly attributable to associated feed demand, up-to-date country-scale quantifications of the land and water impacts of the concentrate feed (mainly cereals and soybean) and co-products required to support pig production are still missing. In addition, the specific role that international feed trade plays in separating resource use from consumption and in altering resource use efficiencies remains unclear. This paper analyses at a country-scale the internal and external consumption of natural resources (i.e., land and water) to support pig feed production in 2018. Combining data on the country- and production system-specific diets and crop-specific yields with an agro-hydrological model, we find that 64.1 Mha of agricultural land (5% of all croplands) and 332.6 km3 of water (both green and blue) (6% of all agricultural water use) were utilized by China, EU-27 and the United States (accounting for 70% of pigmeat production) to produce pig feed alone. Comparing domestic feed production scenarios with those that also consider the feed trade, we show that global resource consumption tends to be more efficient when considering international feed trade, especially in China and EU-27, while sometimes causing significant environmental impacts. This demonstrates the need to investigate the environmental effects of pig feed associated both with the domestic use of natural resources, but also to the ones displaced by international trade.

In recent decades, climatic and anthropogenic pressures have caused serious environmental problems. The joint analysis of geo-environmental variables, through geoprocessing techniques, can support the estimation of the contribution of each environmental component to hydro-environmental fragility (HF). The aim of this work was to analyze the contribution of climatic phenomena and deforestation in the HF of the Gurupi River Watershed (GRW). Precipitation data were extracted from the Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS); land use and cover were obtained from the MapBiomas Project; drainage network was acquired from the National Water and Sanitation Agency (ANA); slope data were gathered from the National Institute for Space Research (INPE); soil data were obtained from the Brazilian Agricultural Research Corporation (EMBRAPA); geomorphological units were extracted from the Brazilian Institute of Geography and Statistics (IBGE); and rock data were based on the Geological Survey of Brazil (CPRM). For the mapping of HF, the Analytic Hierarchy Process (AHP) was adopted to weigh the importance of each variable in four extreme precipitation year scenarios (1989, 2012, 2015, and 2019). It was observed that spatial precipitation is considerably different in extreme years. Results showed that deforestation has increased over the years; and that static geo-environmental variables (drainage, slope, soils, geomorphological units, and rocks) have larger feature domains that favor the increase of HF in the GRW. The HF of the GRW showed significant differences in the analyzed scenarios. Policies and environmental conservation programs are needed in the GRW.
