“…The ‘backwards’ construction of the ToC, starting with the human‐jaguar interactions and then adding their most immediate drivers followed by the indirect causal factors and finally the interventions—and appropriate facilitation that encourages participants to reflect on different levels of the drivers of interactions, from ecological to psychological to social to societal—inevitably surfaces drivers that tend to be overlooked when researchers and decision makers are unfamiliar with the human dimensions of HWI. While the causal relationships involving ecological and environmental factors are in general corroborated by empirical evidence (e.g., ‘outdated agricultural practices’ is a driver of ‘wildfires’, Teodoro et al, 2022), several connections between social factors are suppositions that require support from social science research (e.g., ‘preventive/retaliatory killing’ caused by ‘perceived risk’ which is changed by ‘social marketing campaign’).…”

Human‐wildlife coexistence as a concept and management objective has received increasing attention from researchers and decision makers. The coexistence approach will benefit from the recognition that, at broader scales, human‐wildlife interactions (HWI) are best understood and managed collaboratively and as complex systems, that is, dynamic, non‐linear, emergent, adaptive and, therefore, unpredictable. We present a planning process for human‐wildlife coexistence that provides a platform for collaboration between researchers and decision‐makers—and other stakeholders as well—and recognizes the complex nature of HWI. The three elements that define the process are: coexistence instead of conservation or conflict mitigation as a goal, systems thinking as the approach, and an emphasis on verifiable results rather than actions. As a way of illustration, we describe a 3‐day planning workshop for human‐jaguar coexistence in the Pantanal, Brazil. The 15 participants representing the academic, governmental, and non‐profit sectors identified 12 interactions directly involving 27 stakeholders and indirectly another 55. A theory of change was produced, connecting 20 actions—to be performed by 22 actors—with the 57 factors that directly and indirectly drive the interactions. How these results complement other approaches such as Action Plans is discussed. The proposed approach favors the pragmatism of adaptive co‐management over the often unrealistic expectation of a linear path to solution, or in other words, a shift from the notion of human‐wildlife coexistence as a quantifiable target to that of coexistence as a desired system state.

“…Using fire in São Paulo state to manage agriculture, mainly related to sugarcane plantations [35], i.e., clean plantations, reducing aboveground biomass (especially leaves), and facilitate sugar cane harvest was a common practice in São Paulo state until 2002, when a state law regulated gradual elimination of fire for that purpose (Law n 11.241/2002: [36]). According to this regulation from 2011 to 2016, 50% to 80% of elimination of fire use in sugarcane mechanized sites should be pursued (in 2021 that would be 100%).…”

The relationship between forest fire and deforestation in the southeast Atlantic rainforest

Given the scarcity of studies relating fire to deforestation in the Atlantic Forest and great economic and ecological importances of this biome, this work aimed to investigate this relationship in the Atlantic Forest of the State of São Paulo, trying to answer whether deforestation is related to fire events in up to three years, if there are regions most affected by this relationship and what land use and land cover predominates after fire and deforestation in these areas. The study was carried out in Evergreen Forest and Semideciduous Seasonal, along the time series from 2000 to 2019 using the MapBiomas Project database to survey deforested and burned sites with moderate to high severity fires. Burning positively influenced deforestation in EGF in eight of 19 years studied (2001, 2004, 2005, 2007, 2008 and 2009, 2013 and 2015), while only for three years in the SSF. Burning followed by deforestation corresponded to only 3.2% of the total deforestation, located mainly in the eastern region of the state with the highest density in the EGF. Most of these areas have been converted to agriculture. This study provides the first indication that, generally, fire is not a driver of deforestation in the southeast Atlantic Forest.

“…In addition, in the last few years, studies have been applying drought indexes to verify the relation to wildfires occurrences in biomes and regions in Brazil: Alvarado et al (2017), found increasing fire occurrence during the driest periods in Cerrado; Marengo et al (2021) identified droughts by indexes such as VHI, concluding that water and heat stress increases flammability thresholds in Pantanal; and Teodoro et al (2022) verified that the trend of fire occurrence in the Midwest, Southeast, and South regions of Brazil is related to precipitation, land surface temperature and SPI.…”

Brazilian biomes have been experiencing an increase in fires during the whole year, but fires increase substantially during drier periods. Several indexes might be good indicators of the severity of the droughts, such as The Rainfall Anomaly Index (RAI), Standardized Precipitation Index (SPI) and the Vegetation Health Index (VHI). This study therefore aimed to understand the dynamics of climate, using some indexes and fires in Paraíba do Sul River Valley, Paulista portion, to verify whether fire is more likely to spread in hotter and drier years. We hypothesized that fire events are more frequent and burned areas are larger in hotter and drier years in the region. By conducting a cross-correlation analysis and separating the monthly data into dry and rainy seasons, it was possible to establish a correlation between climate parameters and fire. A significant correlation was found between RAI and fires in both seasons. Additionally, we observed that high occurrences of fire events and burning areas were more explained by RAI, VHI and SPI-3 in dry and wet seasons than by temperature and SPI-1, SPI-6 and SPI-12. We noticed a complex dynamic between fire events, burned area, the environment, and climatic variables. However, the studied indexes proved to be effective tools for detecting drought conditions in the region and their relationship to fire. Keywords: burning, climatic indexes, Paraíba do Sul River Valley.
