The Copernicus Sentinel-2 mission takes us at the Brazilian-Bolivian border over part of the Pantanal region, a unique ecosystem, home to an impressive variety of plants and wildlife.

Covering an area of up to 200 000 sq km, the Pantanal is the largest floodplain in the world and a wetland of international importance. It is mainly located within the Brazilian states of Mato Grosso and Mato Grosso do Sul, but it also extends into Bolivia and Paraguay.
This image from September 2025 captures a small fraction of the Pantanal, which straddles the border between Bolivia to the west, and the Brazilian states of Mato Grosso to the north and Mato Grosso do Sul to the east. A complex mosaic of flooded grasslands, savannas, tropical forests, rivers and human settlements are visible in the image.
The dark green corridor slicing vertically through the centre is dense, ‘riparian’ vegetation – which is found along the floodplain channels and permanent wetlands. In contrast, the surrounding savannas are visible in brown.
The Pantanal acts as an enormous internal delta, where several rivers merge, feeding the vast network of wetlands. The Rio Paraguay, seen meandering across the green lush band, is the most important river in Pantanal as its natural flood cycle creates the region’s unique environment and supports its diverse fauna.
Following the riverbed southwards, we can see some urban structures. The largest to the west is the Brazilian city of Corumbá, which serves as a gateway to Pantanal. Its rectangular grid is surrounded to the south by a patchwork of fields and brownish pastures.
The reddish-brown areas are expanses of cracked clay soil, which are exposed during the dry season. These areas, barren in September when this image was acquired, become green during the wet season from November to April.
The two conurbations visible west of Corumbá are the inland ports of Puerto Suarez and Puerto Quijarro, on the Bolivian side of the border. The light brown patches on the left represent savanna and forest cleared for cattle pastures and ranches. The thin strips of land are most likely cultivated soybean fields.
This region has undergone significant deforestation in recent years, with some areas transformed from dense forest into a mosaic of fields.
