Researchers from the Advancing Systems Analysis (ASA) program recently participated in a seminar inviting expert dialogue on the role of BRICS competition authorities in the fast-maturing era of artificial intelligence (AI) and whether authorities from BRICS and beyond can cooperate on a common vision for AI in the interest of societal welfare.

Once a collection of fragmented technologies with limited applications, AI has rapidly evolved into a crucial driver of innovation across diverse sectors, including the digital economy. However, the AI industry is at risk of becoming oligopolistic under existing Big Tech. Through investments and partnerships, Big Tech has already positioned their influence in the development of AI while avoiding conventional regulatory merger probes.

The recent partnership between Microsoft and OpenAI is a prime example. Such cases have focused attention on the pressing need for competition authorities to adapt and harmonize their approaches to regulating the digital economy.

On 12 September 2024, Elena Rovenskaya presented (virtually) at the BRICS Seminar on Artificial Intelligence Regulation hosted at the School of International and Public Affairs of Shanghai Jiao Tong University in Shanghai in collaboration with the BRICS Competition Law and Policy Center. The seminar invited presenters from various experts from BRICS nations involved in the development of AI regulations.

A working paper on this topic is published on the Research Square preprint server.

In her presentation, Rovenskaya discussed how integrated systems analysis can enable competition authorities to better evaluate the potential outcomes of strategic partnerships between entities in the digital economy that typically fly under the radar of merger criteria. Specifically, she introduced system dynamics modeling, including causal loop diagrams, which enable us to illustrate complex systems as a set of interacting components whereby the components and their relevant interactions are informed by literature, expert opinion, or stakeholder input.

The latest explorations of the ECOANTITRUST reveal the potential loss of strategic independence for AI service providers through various partnerships with Big Tech incumbents. In 2019, for example, Microsoft and OpenAI entered a partnership involving various investments and product integrations. Despite increasing concerns, several competition authorities have failed to realize probe into the partnership.

Rovenskaya presented analysis developed by the ECOANTITRUST team, informed by public discussions on the Microsoft-OpenAI partnership following their governance controversies of the latter in late 2023. The analysis indicates numerous pathways and feedback loops through which the reduction of the strategic autonomy of Open AI affects competition and innovation in the AI sector.

The presentation was well-received, with experts commenting that the need to integrate systems-led analysis into competition law is greater than ever before.

The number of days per year that are simultaneously extremely hot, dry, and have a high fire risk have as much as tripled since 1970 in some parts of South America.

South America is warming at a similar rate to the global average. However, some regions of the subcontinent are more at risk of the co-occurrence of multiple climate extremes. These compound extremes can have amplified impacts on ecosystems, economy, and human health.

Raúl Cordero and colleagues calculated the number of days per year that each approximately 30 by 30 km grid cell on the South American continent experienced simultaneous hot, dry, and flammable extremes between 1971–2022. The results are published in Communications Earth & Environment.

Extremes for each condition were calculated from daily maximum temperature records, 30-day rainfall averages, and daily fire weather index records. The authors found that the frequency of these simultaneous extremes had increased across the entire continent.

There were particularly high increases—from fewer than 20, to as many as 70 days per year—around the Venezuela–Colombia border, in the northern Amazon, and in the north of the Río de la Plata basin in central South America. The authors also found that there was an increase in the variability of these simultaneous events from year to year over the past five decades.

The authors additionally found that the likelihood of the compound conditions occurring on a regional basis was affected by the El Niño-Southern Oscillation. During the warm El Niño phase, fire risk increased in the northern Amazon region, while the cooler La Niña phase led to increased fire risk in central South America.

The authors caution that increased fire activity and dry extremes are both a public health hazard and can cause further warming through the release of black carbon to the atmosphere.

They also highlight that these extreme events disproportionally affect vulnerable rural and indigenous populations, and suggest that policymakers in the region should have a greater focus on mitigating these extremes.

Hydrilla verticillate (hydrilla), one of North America’s most invasive species, has been found for the first time in Canada. Dr. Rebecca Rooney, a biology professor, and members of her Waterloo Wetland Laboratory were surveying a secluded section of the Hillman Marsh Conservation Area in Leamington, Ontario, when they found the unexpected species. Upon review, the Ministry of Natural Resources and Forestry confirmed their findings.

Why is one little plant so worrisome?

Hydrilla is an aquatic plant that spreads quickly and can take over entire wetland environments, threatening the diversity of plants and animals in ecosystems. Hydrilla can also limit recreational use of these areas because it can get tangled in boat motors, clog water-intake pipes and inhibit activities like swimming and paddling, hindering our ability to enjoy Ontario’s beautiful lakes and wetlands.

“We hope to eradicate it before it can spread,” says Rooney, an expert on invasive species in Canada. “It’s currently in an area isolated from Lake Erie and other wetlands, which is good news. This will enable us to treat the infested area without impacting the larger water system.”

Removing all hydrilla in Hillman Marsh could take several years, but Rooney and her team will be involved in the eradication efforts. The team plans to monitor the use of different tactics to remove the hydrilla from the area, such as administering approved herbicides and dredging.

“We need to study how effective the different treatments are to control hydrilla so that if it is found again, we will have a removal plan ready that we know works,” Rooney says.

Discovering this invasive species during survey work underscores the importance of environmental monitoring across the province and country. If researchers aren’t doing hands-on work in the field, they’re missing opportunities to catch infestations of invasive species before they are unmanageable.

“Timing is so important, because there’s a tipping point for invasive species where we start to consider them established, and it changes from a goal of eradication to a goal of containment,” Rooney says. “Once you’re in an established invasion, you’re committed to ongoing management costs, and that eats into our conservation dollars that could be better spent fighting climate change and promoting habitat biodiversity.”

Ontario spends millions of dollars a year on invasive species management to contain the invasive plants already present, and while scientists and researchers are doing the heavy lifting in that aspect, the public can also play a role in slowing the spread.

“It’s important to follow the Clean, Drain, Dry method after being in the water,” Rooney says. “You should clean anything used, drain anything that was submerged and ensure it is completely dried before putting it into another body of water. Hydrilla can spread very easily by even a single tuber ,and it’s up to all of us to keep our water safe.”

Grocery stores that donate expiring food instead of price discounting or discarding make higher profits, says researcher

All major supermarkets and retailers that sell groceries, such as Kroger, Walmart and Costco, give large amounts of food to food banks and pantries. In 2022, retailers donated close to 2 billion pounds of food across the United States, which amounted to US$3.5 billion that year. The estimated value of donated food was a little less than $2 per pound in 2022.

Retailers donate products that are typically packaged, palatable and safe for consumption, yet unsuitable for sale due to quality concerns, such as minor blemishes. Since these items can go a long way to feeding hungry people, donations represent one of the best uses of leftover or surplus food.

Donations are also technically acts of charity, and the companies responsible for them get tax breaks. This means that donations boost profits by lowering costs. There’s a second effect of donations on a store’s bottom line: They improve the quality of food on the store’s shelves and increase revenue from food sales.

As a supply chain scholar who studies food banks, I worked with a team of economists to estimate the effects of retail food donations. We used sales data for five perishable food categories sold by two competing retail chains, with stores located in a large, Midwestern metropolitan area. We found that stores that remove items on the brink of expiration, donate them to food banks and fill up the emptied shelf space with fresher inventory get more revenue from sales and earn higher profits.

Retailers donate 30% of what food banks give their clients

U.S. food banks, which have been operating for more than 50 years, give away over 6 billion pounds of food annually.

They get about 30% of that food for free from supermarkets and big-box retailers that sell groceries. Prior to the start of the COVID-19 pandemic, retailers supplied more than twice as much food to food banks as the federal government did. The volume of food supplied by federal programs administered by the United States Department of Agriculture, such as the Emergency Food Assistance Program, has steadily increased since 2020, to now almost match the volume of food donated by retailers.

In 2022, for example, the network of more than 200 Feeding America member food banks procured about 2 billion pounds from retailers and almost 1.5 billion pounds from government programs.

The remaining 2.88 billion pounds of food were either purchased directly, provided by farmers, donated by food processing companies or donated by people and organizations in local communities.

Despite several federal programs that help low-income people get food and the nation’s robust network of food banks and food pantries, nearly 50 million Americans are experiencing food insecurity. That means they can’t get enough nutritious food to eat at least some of the time.

Retail donation routines are established but inconsistent

When food on a store’s shelves is on the verge of expiration, store managers have three options. They can donate or discard it, or sell it at a discount.

Stores that regularly donate food have established routines for when they set aside about-to-expire food to give away. However, these routines are often inconsistent.

Many stores donate only on a seasonal basis or just give away certain kinds of food. For example, they might donate only meat, baked goods or fruits and vegetables. In many cases, donations take a backseat to more immediate priorities, such as customer service.

Those realities can increase the likelihood that food will land at the dump instead of on somebody’s table.

Although millions of Americans struggle to find their next meal, close to 40% of food gets thrown out along the supply chain, as food moves between agricultural producers, factories, retailers and consumers. This is largely due to logistical challenges: It’s hard to transport and distribute highly perishable food.

Discounts on food can undercut sales

Stores often prefer to sell food on the brink of expiration at a discount rather than donate it or throw it out due to the money they recoup that way. This option, however, also keeps the discounted food on the shelf, where it takes up valuable space that could otherwise hold fresher inventory.

Shelf space dedicated to the sale and promotion of full-priced products competes with that for price-discounted food. Stocking perishable foods that are starting to look iffy—such as bananas with brown spots sold alongside unblemished yellow bananas—could harm a retailer’s image if shoppers start to question the store’s quality.

In other words, if consumers make judgments based on all the produce that’s on display, then it may be better for stores if they don’t sell sad-looking bananas and instead just give them away.

My research team calls this practice “preemptive removal.” Increasing the average quality level of food on display does more than improve a store’s appearance. We used panel data with over 20,000 observations, and we included 21 retail stores that compete in a similar market geography. The five fresh food categories were bakery, dairy, deli, meat and produce.

Stores that donated food, instead of discounting it, may have made better use of the limited room to display fresher inventory. My research team found that food donations can increase average food prices by up to 1%, which corresponds to a 33% increase in profit margins. Profit margins for supermarkets and other food retailers are quite low and typically hover below 3%.

That means even a small increment in food prices, even a 1% bump up, can translate into significantly higher profits for retailers. At the same time, increasing the volume of retail food donations would get more food to people who need it, limit hunger and reduce food insecurity.

Most Americans can expect wetter winters in the future due to global warming, according to a new study led by a University of Illinois Chicago scientist.

Using climate models to investigate how winter precipitation in the United States will change by the end of the 21st century, a team led by Akintomide Akinsanola found overall winter precipitation and extreme weather events will increase across most of the country.

The study in npj Climate and Atmospheric Science also reported an increased frequency in “very wet” winters—those which would rank in the top 5% of U.S. historical total winter precipitation. By the end of the 21st century, these previously rare winters would happen as often as once every four years in some parts of the country.

Combined with a shift from snow to rain in many parts of the country, the changes will have dramatic implications for agriculture, water resources, flooding and other climate-sensitive areas, said Akinsanola, assistant professor of Earth and environmental sciences at UIC.

“We found that, unlike summer and other seasons where projected changes in precipitation is highly uncertain, there will be a robust future intensification of winter precipitation,” Akinsanola said. “It will accelerate well past what we have seen in historic data.”

The team used 19 Earth system models in their study and carried out their analysis over the seven U.S. subregions defined in the National Climate Assessment Report. The study compared projected precipitation at the end of the 21st century (2070-2099) to the present period (1985-2014).

Across the entire United States, they showed an increase in mean winter precipitation of about 2%–5% per degree of warming by the end of the 21st century. In terms of absolute change, the Northwest and Northeast U.S. saw the largest increases. Six of the seven regions will also experience more frequent very wet winters, with the sharpest increases seen in the Northeast and Midwest.

The southern Great Plains—states along the southern border such as Texas and Oklahoma—was the only region where projected changes were very small and highly uncertain. In this region, more frequent extreme dry events will offset or outweigh the increasing extreme wet events, Akinsanola said.

The findings highlight that changes in winter precipitation will have a significant impact nationwide and, in some regions, more impact than expected changes in spring and summer precipitation.

The mix of precipitation also will likely change in many areas. Previous studies have projected that as temperatures rise, more precipitation will fall as rain rather than snow, resulting in lower snow depth. This reduced snowpack plus higher rain will stress existing systems.

“There will be a need for updating or upgrading infrastructure, because we’re not just talking about the mean precipitation, we’re also talking about an increase in extreme events,” Akinsanola said. “Drainage systems and buildings will have to be improved to cope with potential floods and storm damage.”

In current and future work, Akinsanola will use higher-resolution models to predict changes in precipitation, heat waves, compound dry and hot extremes and other extreme events on a more local level. He conducts some of his research in association with the Environmental Science Division at Argonne National Laboratory, where he holds a joint appointment.
