“…Another important aspect to be highlighted is the threat faced by the Pantanal, and therefore, its socio-cultural services. Predictive land use and land cover scenarios show a rapid and threatening change (Roque et al, 2021). First, the surrounding region of the Pantanal is seen as a potential source of hydropower energy, and several small hydroelectric dams are planned to be built in the region (Jardim et al, 2020).…”

Ecosystem services do not exist independently from human perceptions and recognition. They are socially, culturally, economically, and environmentally scale- and context-dependent. Socio-cultural services tend to be difficult to evaluate and invisible to policymakers and conservation practitioners. Based on six years’ qualitative analysis of a floodplain fishery in the Pantanal wetland, Brazil, we bring an in-depth understanding of the socio-cultural ecosystem services in the region. We show that the inter- and intra-annual ecosystem dynamics variations in the flood pulse are closely associated with local people's governance structure, identity, and cosmological histories. All of them, to some extent, capture some of the unpredictable changes in the Pantanal. Our study uncovers part of the complex and rich social-cultural ecosystem service created from the interaction between local people and the ecosystem in which they are embedded. We also present the threats faced by these services in the face of current development projects in the Pantanal, such as the Waterway and Hydrometric Dams. We argue that the predicted outcome may jeopardize not only the social-cultural services in the Pantanal, but also the local people themselves and the environment that they are currently protecting.

“…Recent studies show that deforestation in the rainforest is connected to lower transfer of moisture for the Pantanal wetland 47 . Since deforestation and re are increasing again in the Amazon rainforest 15 , a challenging scenario for the Pantanal also includes other contributing factors such as hydrological changes due to river damming 48,49,50,51 , soil erosion and deforestation in surrounding plateaus 52,53 , which can cause wetland area losses, exposing more areas to the risk of re.…”

Anthropogenic factors have significantly influenced the frequency, duration, and intensity of meteorological drought in many regions of the globe, and the increased frequency of wildfires is among the most visible consequences of human-induced climate change. Despite its role in determining biodiversity outcomes in different ecosystems, wildfires can cause negative impacts on wildlife. We conducted ground surveys along line transects to estimate the first-order impact of the 2020 wildfires on vertebrates in the Pantanal wetland, Brazil. We adopted the distance sampling technique to estimate the densities and the number of dead vertebrates in the 39,030 square kilometers affected by fire. Our estimates indicate that at least 16.952 million vertebrates were killed immediately by the fires in the Pantanal, demonstrating the impact of such an event in wet savanna ecosystems. The Pantanal case also reminds us that the cumulative impact of widespread burning would be catastrophic, as fire recurrence may lead to the impoverishment of ecosystems and the disruption of their functioning. To overcome this unsustainable scenario, it is necessary to establish proper biomass fuel management to avoid cumulative impacts caused by fire over biodiversity and ecosystem services.

“…Land use change in the Pantanal maintains river instabilities and avulsion dynamics contributing for changes in the ecosystem services of provision and regulation and affecting cattle ranching and fishers (Bergier et al, 2018; Louzada et al, 2021). Increased sediment flows derived from the agricultural activities in the UPRB highland contribute to rising pesticide levels in the region (Roque et al, 2021).…”

“…However, attributing the cause of the hydrologic changes to these processes is a difficult task since their feedback effect in the hydrological response varies according to the basin, and depends on the context in which the processes occur (Blöschl et al, 2007). Theoretical numerical studies assessing LUCC and hydrological changes in the UPRB have suggested potential impacts (Assine et al, 2015; Bergier, 2013; Colman et al, 2019; Roque et al, 2021). However, there is a lack of studies regarding the impacts of land‐use change on hydrological extremes, especially low flows, in medium‐to‐large scale basins based on measured data.…”

Impacts of the landscape changes in the low streamflows of Pantanal headwaters—Brazil

The Upper Paraguay Basin Plateau (UPRB) concentrates the headwaters and the largest volume of rain that supply the Pantanal biome and is essential for maintaining its water regime. Given the region's changes in land use and cover, this research sought to identify their influence on headwater flows. The use of conceptual models and time series analysis showed that the replacement of natural vegetation with pasture and the more recent activity of irrigated agriculture have produced changes in the hydrological response of the headwaters. There was a decreasing tendency of low flows during dry periods, which was correlated with anthropic changes in the use and cover of the land in the region. The research results point out changes in land use and cover as the cause of a significant decrease in streamflows during drier periods. Such behaviour at the headwaters of the Pantanal can have consequences for this biome, reducing the resilience of the system against droughts and damaging the biodiversity of the biome.
