People who live in the fishing village of Espinillo Island walk their goods across the Old Parana River delta now that boats can’t reach their community and others, amid a drought that turned the river into a sand bank, across the river from Rosario, Argentina, Thursday, July 29, 2021. The falling water levels of the Parana River worry environmentalists and authorities alike because it impedes river traffic, creates a shortage of drinking water, and effects productivity in the northeast of the country through which the river flows.

ROSARIO, Argentina (AP) — The Paraná River, one of the main commercial waterways in South America, has reached its lowest level in nearly 80 years due to a prolonged drought in Brazil that scientists attribute to climate change.
At peril is a vast ecosystem that includes potable water for 40 million people, the livelihood of fishing communities and farmers, and the navigability of a major grain export hub.
The National Water Institute of Argentina has defined the low water level of the Paraná River, which goes through Brazil, Paraguay, and Argentina, as “the worst since 1944.”
“This natural asset is clearly giving us signs that it’s not infinite,” said environmentalist Jorge Bartoli, coordinator of the organization “El Paraná No Se Toca” (Parana Should Remain Untouched).
The low water level is due to a record drought in Brazil, where the river begins.
The midwestern and southern regions of Brazil are in a big water crisis. Water reservoirs, including the giant Itaipu dam, are at their lowest levels in many years and Brazilian authorities have issued an emergency alert for five states: Minas Gerais, Goiás, Mato Grosso do Sul, São Paulo and Paraná.
Reduced water levels are part of a natural cycle, but specialists warn that the scenario is more extreme because of climate change.
“These climate changes that were less frequent before are becoming more frequent,” said Brazilian climatologist José Marengo.
Environmentalists say deforestation is contributing to the problem.
The Paraná waterway and its aquifers supply fresh water to some 40 million people in countries including Brazil and Argentina.
In turn, it receives water from the Paraguay River, which has among its main sources the Pantanal area, a huge wetland located in the Mato Grosso region of southern Brazil.
The drought of the river is impacting the transport of goods.
Guillermo Miguel, president of the port of the city of Rosario, said vessels had to reduce their tonnage by approximately 20% to continue moving. He said transport costs are increasing.
