YOUR GLOBAL RUNDOWN 

• Many river communities in the Brazilian Amazon — hit with their worst drought in more than 100 years in 2024 — remain isolated, their boats and floating homes damaged. 
• Nearly 10 inches of snow fell in some cities in the deep U.S. South, prompting road and school closures and transportation delays.
• Ghana’s government appears to be prioritizing gold mining over clean water access, jailing activists as supply cut-offs and pollution worsen.
• A combination of over-construction, deforestation, and extreme heat have contributed to the loss of trees and waterways in Chennai, India — resources the city is desperately seeking to restore.

Fresh: From the Great Lakes Region

Reassessing Recreational Fishing Value: For nearly 20 years, the Great Lakes’ recreational fishing industry was said to generate $7 billion annually, a number cited repeatedly by officials, reporters, politicians, and community members. Now, a recalculation ordered by the The Great Lakes Fishery Commission reveals that the true figure is about $5.1 billion, Michigan Public reports. It remains unclear when the $7 billion estimate was no longer accurate.

The Lead

Last September, Ghana’s water agency announced that due to contamination of the country’s main rivers from mining activities, certain communities would be cut off from water supplies. When protestors demonstrated in Accra, hoping to bring attention to this “looming environmental catastrophe” and add water as a ballot measure to the December general election, they were jailed for illegal assembly, Al Jazeera reports.

Environmentalists are pessimistic that the new president John Mahama will put an end to the illegal small-scale mines that are rampant across the country. With the price of gold rising to “close to $3,000 per gram” in late December, the activity known as “galamsey,” which translates to “gather them and sell,” remains profitable, at a detriment to the country’s waters.

By 2017, more than 60 percent of Ghana’s water bodies were polluted with mercury and other toxic metals used in the mining process. Thousands of acres of farmland have been polluted as a result, and in 2022 officials “allowed for mining concessions to be allocated in the country’s biodiversity hotspots, including protected forests.”

WaterAid, an international nonprofit, estimates that by 2030, Ghana may need to import water to meet its needs.

This Week’s Top Water Stories, Told In Numbers

39.7

The lowest level that Brazil’s Negro River, measured in feet at the port of Manaus, reached last year amidst ongoing, debilitating drought in the Amazon basin, the Guardian reports. Compared to its usual level of 68.9 feet, this was the driest the river had been since records began 122 years ago. Despite a wetter January, grounded boats and floating homes remain stranded in and around other Amazon tributaries. Communities that rely on the river for travel are isolated, and fishing economies have suffered — many fishers are forced to walk miles to reach fisheries that are still intact. Overall, an estimated 140,000 families have been impacted by drought conditions. 

31 million

The number of people across the U.S. South placed under a snowstorm warning this week, as communities across the Gulf Coast experienced some of the heaviest winter precipitation they had ever seen, Reuters reports. Four inches of snow in Houston prompted school closures on both Tuesday and Wednesday, while 9.8 inches of snow fell on New Orleans — appearing to break the previous record of 8 inches set in 1898. Mobile, Alabama also experienced half a foot of snow, a depth not seen in 144 years.

On the Radar

In 1988, “residential, commercial, and industrial areas” comprised just 18 percent of the city of Chennai, India. As of 2017 this increased to 50 percent, while agricultural lands were halved and deforestation expanded. Now home to roughly 7 million people, Chennai and the greater Tamil Nadu state face a crisis: Warming temperatures, exacerbated by the loss of tree cover, are disappearing lakes and freshwater bodies while communities struggle to stay cool, DW reports. Some communities, such as Auroville, have already begun action to reverse this feedback loop, reforesting their land and “integrating greenery” into everyday life. They hope to serve as a model for congested urban areas before the negative effects of pollution on human health and water access are irreversible.
