(pəntənäl`), lowland region of SW Mato Grosso state, Brazil, bordering the Paraguay River and extending to the the western edge of the Brazilian Plateau. Parts of the pantanal extend into Bolivia and Paraguay. It is the world's largest wetland area, c.77,000 sq mi (200,000 sq km). Although subject to annual flooding, it is not a marshland; the water is not stagnant, and there is no malaria. The pantanal completely dries out at the end of the six-month rainy season, leaving lush grasslands that are used for cattle grazing. Millions of migratory birds visit the area every year and over 100 species of mammals and reptiles live there. However, the pristine nature of the pantanal is threatened by encroaching ranching and agriculture, poaching, coal mining, and wildfires initially set to clear ranch- and farmland.

a swampy area in Brazil located along the upper Paraguay River. It is situated in a tectonic basin near the western base of the Brazilian Highlands. During the rainy season the area becomes flooded, restraining the freshets of the Paraguay River downstream. In dry periods it is a combination of swamps, lakes, and salt marshes alternating with areas covered with forest, shrub, and grass.

Located in the geographic centre of South America, the Pantanal is the largest wetland plain on the entire planet.
Adiciona-se o fato de que varias comunidades possuem regras e redes sociais estabelecidas para evitar o uso insustentavel do recurso, como este estudo ira mostrar, o caso da Comunidade da Barra do Sao Lourenco, na fronteira oeste do Pantanal, que desde a decada de 1990, com a implementacao de reservas particulares, sofre com a falta de territorio para a manutencao dos costumes tradicionais e recursos basicos a sua sobrevivencia como areas de pesca, o acesso a agua potavel e territorios seguros durante as cheias.
A preocupacao com o impacto de acoes antropogenicas no Pantanal vem sendo tema de diversas publicacoes, uma vez que o desmatamento e queimadas acarretam a prevalencia de novas especies vegetais sobre outras, interferindo na biodiversidade animal e vegetal, nos processos do ecossistema, como o carbono, e na ciclagem dos nutrientes (VOURLITIS et al., 2011; DALMOLIN et al., 2012).
"Brazil is rich in mythologies and spiritual beliefs and we are very excited about this opportunity to show the world more of this side of our culture and even the singularities of the Pantanal region through Netflix," he said in a statement.
The Pantanal is characterized by pronounced wet seasons and is the smallest biome in the country, occupying just 1.76% of the total land area (MMA 2017).
The Pantanal wetlands stand out for being one of the largest flood plain in the world, in which extreme climatic variations occur between dry (April to September) and wet seasons (October to March).
The Tripotheus nematurus sardine is a Triportheidae species that inhabits waterbodies from the Parana and Paraguay River basins (Buckup, Menezes, & Ghazzi, 2007; Britski, Sillimon, & Lopes, 2007; Oliveira et al., 2011), being abundant in the ponds at the Pantanal subregion of the Miranda-Abobral.
The low slope in the Pantanal region makes it difficult to drain the water and, in combination with the meso relief, is possible to observe differents and characteristic environments, associated with the mosaic vegetation, such as the "mountain ranges", with denser tree vegetation, or riparian vegetation, which is very dynamic, due to the sinuous and unstable fluvial beds (Pott & Pott, 2005).
Successful examples have shown that sustainable farming of the Pantanal caiman (Caiman crocodilus yacare) can contributed to a healthy ecosystem (VERDADE, 2004; VICENTE NETO et al., 2010).
