Parana River Hits 80-year Record Low Level

Widespread Economic Impact Felt

14 Feb 2022 by The Water Diplomat

Entire communities across three countries in South America are struggling with extremely low levels in the Parana River. Second in size only to the Amazon River and crossing Brazil, Paraguay and Argentina, the Parana is at its lowest level since 1944.

The impact is being felt in all three countries as Brazil continues to experience its worst drought in 91 years. The historic low water level has hindered grain transportation which used the waterway, has triggered a rise in wildfires, and has damaged entire ecosystems.

In the areas surrounding the Brazilian part of the river, rainfall has halved in the past 30 years and there are fears that this is a trend that will only intensify as a result of climate change and global warming.

Experts also point out more direct human intervention that is having a negative impact on the river’s ability to self-regulate. Dam building, cattle ranching and soybean farming are having a negative impact on wetlands causing a domino effect.

This is having a significant economic impact in the region’s economy with billions of dollars in losses.

In fact, the region is one of the world’s largest producers of soybean and maize, but the ongoing drought has been having an impact not only on yields but also on the ability to transport the grains.  Brazilian authorities estimate that soybean yield could drop as much as 38 percent due to the drought.

Low water levels are also impacting electricity production as the water reaching dams is insufficient to produce the desired output causing price hikes in energy.

Another sector struggling with the drought is fisheries and fishery-related tourism, due not just to the vast arid areas where the river once flowed, but due also to the quick changes in the regions ecosystem.

Forecasts predict that, for the foreseeable future, the region will see below-normal levels of precipitation, which means that the reversal of the situation and overcoming the crisis is something which is not yet on the horizon.
