Amazon river levels fall due to lack of rain, harming navigation

In 2015's record drought in the Amazon and less than normal rains given that caused river water levels to drop quickly, preventing navigation by barges bring grains for export and cutting off neighborhoods that depend on river transportation.

The Brazilian Geological Service (SGB) has actually warned that water levels have actually been falling given that June and all rivers in the Amazon basin are expected to drop listed below their historical levels.

In Manaus, the Rio Negro river is 21 meters deep, below 24 meters at the exact same time in 2023, which is beginning to stress industries in the Free Trade Zone, where companies have asked for dredging work start on the river to avoid last year's. interruption of transportation.

Dredging has begun on critical points of the Madeira river. where just low-draft vessels are able to pass, according to the. government's department of transportation infrastructure DNIT. Dredging work is being contracted for the significant Amazon and. Solimoes rivers, DNIT said.

Following in 2015's drought, barges were prevented from. using some ports on the Amazon river, and the outlook for this. year is even worse, stated consultancy ARGUS.

This could lead to the redirecting of grain and fertilizer. cargoes in the coming months to Itaqui and other ports in the. south and southeast of Brazil, ARGUS stated in a study that. forecasts increased shipping expenses for producers.

In Porto Velho, Rondonia state, the Madeira River has actually been. below two meters given that July, when its regular depth is 5.3. meters, the SGB stated. The river has 2 hydroelectric dams,. Jirau and Santo Antonio, and transport is impacted on one. of the primary waterways for the north of Brazil.

Throughout the Amazon area, communities are dealing with isolation. due to lower river navigability. Citizens can not travel to purchase. food, and crops are being damaged, besides the fish that are. killed when streams dry up, hurting riverside neighborhoods that. live from fishing. In typical droughts, the rivers have sufficient volume to bring. food, little boats. However not now. They have dried up and people. are being isolated, stated climatologist Jose Marengo.

More rain had actually been anticipated in the 2nd half of this year. thanks to the La Niña phenomenon cooling the waters of the. Pacific near the Equator, which should bring more humidity in. northern Brazil and dried weather to the south.

This year, however, the waters of the Pacific have not. cooled as anticipated, which integrated with the lack of rain in. 2023, has led to a devastating situation in the Amazon, said. Marengo, planner of Research and Development at the National. Center for Natural Disaster Tracking and Alerts (Cemaden).

The lack of rain in the Amazon will deprive areas to the. south of wetness through the flying rivers that take water. vapor increasing from the rainforest to the savannah area listed below. the Amazon and additional to southern Brazil, stated Marengo, who. helped coin the term for the undetectable currents of humid air.
