“…Plants and wild animals, for example, are affected by tree mortality in riparian forest after extreme flooding, with consequent habitat modification for wild animals [16]. Extreme hydrological events such as the ones described in the present study have been proven to impact the management of cattle raising in this region, preventing access to, circulation within, and occupation of some grazing areas [20].…”

“…There is an increasing need to improve the forecasting capabilities of local extreme precipitation events originating from regional to global processes. In this sense, searching for correlations with global climatic phenomena can help resolve the hydrometeorological dynamics of the Pantanal [20]. The analysis of the effects of ocean temperature and atmospheric pressure on land temperature and precipitation patterns has been of increasing concern [21][22][23][24][25][26].…”

Quo vadis Pantanal? Expected precipitation extremes and drought dynamics from changing sea surface temperature

et al. 2020

Climate change poses a critical threat to the Pantanal, the largest wetland in the world. Models indicate an increase in the frequency of extreme precipitation events and extended periods of drought. These changes can amplify consequences for Pantanal's ecological functioning, which has already experienced intensive human modification of its hydrological system and environmental health. The present study analyzed the spatial and temporal dynamics of rainfall and resulting extremes in the Brazilian area of the Upper Paraguay River Basin (UPRB) along with a co-evaluation of the global Sea Surface Temperature data (SST). The predicted results indicate that wet extreme precipitation events will become more frequent in the highlands, while severe and prolonged droughts triggered by warming SSTs in the Northern Hemisphere (North Atlantic and North Pacific oceans) will affect the Pantanal. The linear relations between precipitation with SST of very specific oceanic regions and even from specific oceanic indexes obtained in the present study significantly improve the forecasting capacity, mainly from a resulting reduction to two months of the lead-time between SST warming to concomitant precipitation impacts, and by explaining 80% of Pantanal´s precipitation variation from major oceanic indexes (e.g., ENSO, PDO, NAO, ATL3). Current SST trends will result in inter-and intra-annual flooding dynamic alterations, drastically affecting the Pantanal ecosystem functioning, with consequences for wildlife diversity and distribution. Regarding the foreseeable global climate and land use change scenarios, the results from the present study provide solid evidence that can be used at different decision-making levels (from local to global) for identifying the most appropriate management practices and effectively achieving sustainability of the anthropic activity occurring in the Pantanal.

“…The activity has as a characteristic the frequent displacement of livestock according to the availability of pastures, which are always renewed with the passage of water (POTT, 1994). To the pattern of annual floods, which also determines the conditions of access and movement, the Pantanal inhabitant builds its territorial strategies for the upkeep of the livestock (ARAUJO et al, 2018;ABREU et al, 2010;SANTOS et al, 2002). Between 2007 and2014, 32,163,331 bovines were moved in the region (IAGRO, 2015a), predominantly by truck transport (56.38%) and on foot (39.37%).…”

“…Aquidauana is situated in the transition to the Maracaju Mountain Range, also possessing plateau areas in the Upper Paraguay Basin (BAP). In a way, it preserves the municipality of the susceptibility to the floods of the Aquidauana river, a stream of very variable profile in the amplitude of annual fluvial levels (ARAUJO et al, 2018).…”

“…Likewise, despite negative trends in rainfall and river levels starting in the second half of the 1990s (ARAUJO et al, 2018;TOZATO et al, 2013), it is worth highlighting the spatio-temporal variability of the levels of the rivers that drain the Pantanal Sul, which implies intra-regional differences in the pace of the pulse and localized floods. For example, greater intra-annual variability of rainfall, as in the period 2010-2011, which interrupted a severe and prolonged drought that began in 2009 and affected more significantly to the south and southeast (MORAES et al, 2013;LIMA et al, 2011;SOARES et al, 2010).…”

Hydrological Dynamics and Rural Mobility: Considerations on the Cattle Transit in the South Pantanal in Years of Extreme Events: The Drought of 2010 and the Flood of 2014

et al. 2019

The Pantanal is one of the largest wetlands in the world. In Mato Grosso do Sul, the floodplain stands out on the calf production by the use of native grasslands as pastures. It has as a management characteristic the movement of the herds between lowlands and higher areas, at the pace of the annual floods. The commercialization of cattle for rearing, fattening or slaughtering with other localities consolidates an'always in motion'livestock farming. Severe hydrometeorological events act as forcings on the management of production, which may impact on increased costs and losses. To contribute to the understanding of the territorial organization of the activity in the region, this study identified the multiannual pattern of cattle traffic at intra and intermunicipal scales and between lowland and plateau areas between 2007 and 2014. In addition, it presented the dynamics of cattle displacement in Aquidauana and Corumbá, municipalities with the largest areas of wetlands and cattle production of the South Pantanal, considering the episodic events of drought in 2010 and full in 2014. The results showed that the flow of cattle presents different levels of connectivity, with emphasis on intra-Pantanal displacement. Increases were observed in the periods of drought and pre-flood and decrease in the flood months; as well as an occasional intense flow in 2014, suggesting an emergency. This endorses adaptive strategies and the need for actions that minimize the impacts of weather and climate variability on cattle breeding in the region.

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.
