US Blueprints for a 'national cloud' have been drawn up. Big Tech wants in.

David Ingram and Jacob Ward

Fri, October 22, 2021

Big tech has big designs on a big cloud.

A steady drumbeat from some of the most influential executives in the technology industry has emerged in recent months to push the idea that the U.S. government should invest in a "national research cloud" — a hub for U.S. research into artificial intelligence where researchers from academia and smaller tech companies could share data sets and other resources.

It's an idea that has been backed by a government commission led by ex-Google CEO Eric Schmidt and including executives from Amazon, Microsoft and Oracle, which recommended that the Biden administration create a hub for U.S. research into artificial intelligence. The White House has warmed up to the idea, ordering another report on it due next year with an eye toward competing with China on the development of artificial intelligence.

“We should be able to stay ahead of China. We estimated that we are one to two years ahead of China, broadly speaking, in this area. I hope that’s true,” Schmidt said in an interview with NBC News.

“Investments that are targeted in research — new algorithms — should be able to keep us ahead,” he said.

The stakes could be enormous. Some experts in artificial intelligence believe it has the potential to transform the economyautomating some jobs, while creating new ones — and the potential military applications have spurred investment by the Pentagon.

But this month, the idea began getting fresh pushback. Research groups including New York University's AI Now Institute and Data & Society, a nonprofit technology research group based in New York, say the very tech companies pushing this idea stand to profit from it, because the national hub would likely be housed in the same companies' commercial cloud computing services.

They say that's a conflict, and little more than a cash grab by what's effectively the next generation of military contractors. The plan also could entrench the very same tech companies that President Joe Biden's antitrust enforcers are working to rein in, these critics say.

"What this essentially is, is a subsidy to large tech companies," said Meredith Whittaker, a co-founder of the AI Now Institute, a research center for artificial intelligence at NYU.

A former researcher at Google, Whittaker was active within the company in pushing back against its handling of AI ethics. She left in 2019 and has continued to be a consistent critic of how large tech companies handle AI research and its impact.

Whittaker pointed out that the Biden administration pledged in July to rein in a "small number of dominant Internet platforms" that use their power to "extract monopoly profits."

"We need to break out of these narrow frames that are set by self-interested tech oligarchs," she said.

Other criticisms from her and fellow researchers are that the government has barely put thought into the privacy issues or potentially harmful influence of ramping up AI research, and that the alleged competition with China to win an AI arms race may be exaggerated in a replay of Cold War panic.

The idea of a national cloud for AI has been kicking around for years as a way to provide cutting-edge computing power to academic researchers and other people who don't happen to work at a place like Google or Amazon, which have specialized and lucrative divisions dedicated to cloud computing.

One potential advantage, advocates say, is that a national cloud could be the home for huge, secure sets of data that could help train AI systems. Some Americans fear that Chinese researchers have a leg up in AI development because they already have access to large, government-sanctioned data sets in China.

This month, the AI Now Institute and Data & Society submitted written comments on the idea. They argued that the plan for a national cloud would help big tech companies consolidate power and that a Cold War-style competition with China was misleading and dangerous.

“Winning at whose expense?” Brittany Smith, policy director for Data & Society, said in an interview. She said the federal task force that's reviewing the idea should consider evidence that large-scale AI systems result in discriminatory treatment, and proceed with caution.

“It’s always just, ‘Go go, go. Launch the thing. Build the thing. Scale the thing,’” she said. Researchers need to take time, she said, “talking about the costs and talking about who’s hurt and why they are considered expendable in this fake race to do things that don’t actually make any sense.”

More skepticism has come from other organizations. The Electronic Privacy Information Center, an advocacy group in Washington, said in written comments this month that the government should “set rigorous restrictions on the influence of companies involved,” in part to protect civil liberties.

Andrew Moore, head of Cloud AI at Google Cloud and a member of the federal task force on the subject, said in an interview that the role of Google and other corporations would be limited in any national effort.

"It will be driven by academics and the government funding agencies that are involved," he said.

And, he said, it's important that no single cloud-services provider take on a dominant role. A national cloud would be more like a "multi-cloud," he said. "We would never want to see a future where researchers were tied to specific clouds. We very much believe in competition, both among the big established cloud providers and many of the other folks that are involved."

Last year, a bill to develop a national cloud got bipartisan support in Congress as well as endorsements from tech companies and several large research universities.

Another boost came in March, when the federal commission chaired by Schmidt included a national cloud among its recommendations for winning an AI arms race against China. The commission also included Oracle CEO Safra Catz; Andy Jassy, who has since become the CEO of Amazon; and executives at Google and Microsoft.

Representatives for Amazon, Microsoft and Oracle did not respond to requests for comment. The federal government is already a big customer of commercial cloud computing services.

Next up, the Biden administration and Congress are weighing a major investment of money. In June, the White House announced the creation of a task force to help draw up a blueprint for a national cloud — which would officially be called the National Artificial Intelligence Research Resource, or NAIRR.

The task force is due to submit an interim report to Congress in May and a final report in November 2022.
Boom times for Shell amid record gas prices

Shell

Major oil companies are expected to reveal booming profits after global gas prices soared.

Shell is forecast to post quarterly revenue of $2.1bn (£1.5bn) for its natural gas division when it reports on Thursday, an almost three-fold increase on the same quarter last year.

Gas prices have climbed globally amid a global crunch in supplies, with Asian spot liquified natural gas prices four times higher than during the third quarter of 2020.

The rally is leading to painful increases in household bills across Britain and Europe, while factories have been forced to curb output.

None the less, higher prices mean windfalls for producers as well as potentially for the pension pots invested in their stocks.

Oil prices have also climbed, with Brent Crude rising more than 60pc since the start of the year to more than $85 on Friday.

Shell’s shares have climbed 35pc this year, to 1,749p, while BP’s have climbed 40pc to 356p.

Analysts at HSBC expect cash flows for the third quarter - covering July to September - among integrated oil companies to be double than those of a year ago.

“The strength of oil and gas prices means the companies are even more free cash positive than we had already expected,” they said.

“While some of this excess free cash should enable them to accelerate low-carbon spending, much of it is likely to be seen in cash returns to shareholders.”

Shell is reaping the rewards of its £47bn purchase of rival BG Group, a major liquefied natural gas producer, in 2016.

FTSE 100 rival BP is set to report third quarter results on November 2.

HSBC believes its results “will show the strength of its excess free cash flow,” albeit its “leverage to stronger oil and gas prices isn’t as great as many of its peers”.

The sector is under growing pressure to invest more in renewable energy and cut carbon emissions.

BP announced plans last year for a 10-fold increase in low carbon investment by 2030 and a 40pc fall in its own oil and gas production by 2030.

Shell plans to cut the net carbon footprint of its products by 20pc by 2030 and by 100pc by 2050.

The Great Resignation gives way to the Dee Snider workforce

“We've got the right to choose it

There ain't no way we'll lose it

This is our life, this is our song”

—“We’re Not Gonna Take It,” Twisted Sister

What to make of the labor market, where unfilled jobs are near a record high, unemployment claims hit yet another pandemic-era low — but workers appear to be in a particularly foul mood and, as Dee Snider famously bellowed, are simply not gonna take anymore?

With her comprehensive dispatch on the state of an unhappy labor force — where strikes and support for organized labor are on the rise — Yahoo Finance’s Dani Romero hit the nail on the head. It highlights how The Great Resignation is clearly stressing out the workers left behind:

“From health care to entertainment, nearly 100,000 U.S. workers are either striking or preparing to strike in a bid to improve working conditions,” Romero wrote. “New data signals that worker unrest is growing: a Cornell Labor Action Tracker shows that more than 180 strikes have been recorded this year, and over 24,000 workers have walked off the job this month.”

Over at TKer, former Morning Brief scribe Sam Ro (in his newly inaugurated Substack blog) also breaks it down succinctly: “People are quitting low-paying jobs for higher-paying jobs. People are quitting great jobs for even better jobs. People are quitting to become their own boss. People are quitting because they don’t actually need the income.”

To summarize, workers are not only quitting at historically high rates, they’re being increasingly choosy about picking their next jobs. The tight labor market is creating a self-reinforcing loop: Demand is strong, and prices are rising everywhere, but so are wages, as desperate employers trip over themselves to hike pay in a bid to retain and attract talent.

Goldman Sachs tracking data shows wages are rising sharply.
Goldman Sachs tracking data shows wages are rising sharply.

Added to the mix are several other components conspiring to make long-term trends “more inflationary,” Deutsche Bank chief economist Jim Reid wrote this week. These include less support for globalization (which has kept pay low), the shift away from fossil fuels, and — wait for it — “declines in the working-age population causing labor shortages.”

All of these factors are heaping more pressure on an economy and workforce that are clearly in transition. Companies are paying more, which has the ancillary effect of boosting demand and price pressures: Both BlackRock (BLK) and Goldman Sachs (GS) recently warned about rising wage costs. 

Still, it’s simply not sufficient to placate anxious workers in virtually every industry.

The Morning Brief has previously covered the double-edged sword of rising pay, which is giving workers unparalleled bargaining power. However, it puts upward pressure on inflation, which threatens to “ravage” the economy, as former President Donald Trump told Yahoo Finance a couple of weeks ago.

So where does that leave employers? Struggling to fill open jobs while also bending over backwards to keep their current staff happy. And by all indications, the dynamic is less than healthy.

“Corporations aren’t as culturally fluent as they need to be,” The Britto Agency's Marvet Britto told Yahoo Finance Live on Thursday, speaking about Dave Chappelle’s Netflix backlash. Engaging stakeholders “must happen... in order to navigate the landmines and trip hazards that organizations will continue to face,” she added.

The situation at Netflix — buffeted by bad press in the wake of the Chappelle flare-up — is a bit of its own animal.

Although the stock set a new record high on Thursday (I covered some of the reasons why earlier this week), the streaming giant’s conundrum shows how big companies are being forced to navigate a fraught workplace defined by employee activism, picky hires-in-waiting, and more demanding customers. That only feeds the impression of unhappy workers and out-of-touch employers.

Turkey slams Israel’s plans for new settlements in West Bank


http://ahval.co/en-129867

Oct 23 2021 

Turkey’s foreign ministry sharply criticized Israeli plans to begin construction of new settlements in the Palestinian controlled West Bank in a press release shared on Saturday.

In their statement, the ministry condemned plans to create 3,100 new housing units across the West Bank.

"Unilateral and unlawful policies, including the expansion of illegal settlements, that destroy the vision of a two-state solution, which is the only option for a just, lasting and comprehensive settlement of the Palestinian conflict, must be ended," the foreign ministry said in a statement.

"We call on the international community to take action to ensure the protection of the Palestinian territories and the rights of the Palestinian people, in order to achieve lasting peace and stability in the region in the long term."

Turkey has frequently criticised the Israeli government for its settlement activities on Palestinian territory. Ankara has been a vocal critic as well of overall Israeli policy towards the Palestinians, with President Recep Tayyip Erdoğan referring to Israel as a “terrorist state” in the past over its actions in the Palestnian lands.

Turkey and Israel were once strong allies, but relations deteriorated after the 2010 Mavi Mamara incident when Israeli commandos killed 10 Turkish citizens trying to enter Gaza by sea. The two were initially thought to be considering how they could reconcile ties, but this was disrupted by Erdoğan’s criticisms of Israel for its May military campaign in Gaza.

However in early July, Israel’s President Isaac Herzog received a phone call from Erdoğan, congratulating him on his election victory. The two reportedly discussed the “high potential for cooperation in the field of energy, tourism and technology” between the two countries.

US concerned about Israeli plans for 3,000 settler homes

The announcement about settler housing plans comes amid media reports that Prime Minister Naftali Bennett is under extra US pressure to freeze such plans.

The US is “concerned” by the IDF’s intention to advance plans for 3,000 settler West Bank homes, including for the legalization of two outposts.

It is the first such large-scale advancement of settler housing plans by the Higher Planning Council for Judea and Samaria since US President Joe Biden was sworn into office.

The announcement comes amid media reports that Prime Minister Naftali Bennett is under extra US pressure to freeze such plans. Cabinet ministers and officials close to Bennett have denied those reports.

US State Department spokesman Ned Price was queried about the announcement at Friday’s news briefing.

“We are concerned about the announcement of a meeting next week to advance settlement units deep in the West Bank, and believe it is critical for Israel and the Palestinian Authority to refrain from unilateral steps that exacerbate tension and undercut efforts to advance a negotiated two-state solution,” said Price. “This certainly includes settlement activity, as well as retroactive legalization of settlement outposts.”

The council usually meets four times a year to advance settlement plans, but this year it has met only once, in January, to promote plans for 780 settler homes, a fraction of the amount it advanced in past years.

According to the left-wing NGO Peace Now, the Higher Planning Council pushed forward plans for 12,159 homes in 2020, and advanced plans for 8,457 settler homes in 2019.

The council had initially been set to convene in August to approve plans for 2,223 settler homes, prior to Bennett’s departure for his first meeting with Biden.

That meeting was canceled due to a strike and has only now been rescheduled, with a larger number of planned homes.

The Civil Administration has said that it intends to debate 30 projects that involve plans for 3,144 homes. Out of those, 1,800 homes will receive final approval.

This includes plans for the legalization of both the Mitzpe Danny outpost as a new neighborhood in the Ma’aleh Mishmash settlement, and the Haroeh Haivri as an educational institution, according to Peace Now. It added that its count of the plans came to 2,862, due to the double-counting of some plans.

On October 31, the council is also set to advance six projects totaling 1,303 homes for Palestinians in Area C of the West Bank, which is under IDF military and civilian control.

This includes 270 homes in Al-Ma’assara village in the Bethlehem area, 233 homes in Almasqufa in the Tulkarm area and 200 in Dkeika in the South Hebron Hills.

In addition, plans for the Jenin area will be debated regarding 160 homes in Abba a-Sharqiya, 170 homes in Khirbet Abdallah Younas and 270 in Bir Albasha.

Of all those, only the 170 homes in Abdallah will receive final approval. A plan for 50 Palestinian homes in Khirbet Zakariya in the Gush Etzion region was dropped.

Israel to build over new ILLEGAL 1,300 W.Bank settler homes

The announcement from the housing and construction ministry in right-wing Prime Minister Naftali Bennett's government said tenders had been published for 1,355 homes in the West Bank, which has been occupied by Israel since the 1967 Six-Day War.

Those new homes add to the more than 2,000 residences which defence sources have said in August would be authorised for West Bank settlers.

Final approval is expected from the defence ministry this week for those homes.

Palestinian prime minister Mohammed Shtayyeh, speaking at a weekly cabinet meeting, called on world nations, and especially the United States, to "confront" Israel over the "aggression" that settlement construction poses for the Palestinian people.

The Palestinian Authority will be keenly watching for a response from US President Joe Biden's administration, which has said it opposes unilateral Israeli settlement construction as an obstacle to the two-state solution to the conflict.

About 475,000 Israeli Jews live in settlements in the West Bank, which are considered illegal under international law, on land Palestinians claim as part of their future state.

'Wake up'

Jordan, a key Israeli security partner with whom Bennett has sought to improve ties since taking office in June, condemned the announcement as "a violation of international law."

Jordanian foreign ministry spokesman Haitham Abu Al-Ful blasted settlement construction and general "confiscation" of Palestinian land as "illegitimate."

Anti-occupation group Peace Now said Sunday's announcement proved that Bennett's ideologically diverse coalition, which ousted ex-premier Benjamin Netanyahu's pro-settlement government in June, was not "a government of change."

"This government clearly continues Netanyahu's policy of de facto annexation," Peace Now said, calling on Bennett's left-wing governing partners, the Labor and Meretz parties, to "wake up and demand the wild building in settlements cease immediately."

Bennett, the former head of a settler lobby group, opposes Palestinian statehood.

He has ruled out formal peace talks with the Palestinian Authority during his tenure, saying he prefers to focus on economic improvements.

The tenders come after Israel last week gave approval for 4,000 Palestinians to register as residents of the West Bank, the first such move in the Israeli-occupied territory in 12 years.

The new Jewish homes are to be built in seven settlements, according to the statement from the Housing and Construction Ministry.

Israeli settlement expansion in the West Bank and annexed east Jerusalem has continued under every Israeli government since 1967.

However, construction accelerated in the last few years under Netanyahu, with a significant boom during former president Donald Trump's US administration, accused of egregious pro-Israel bias by Palestinians.

Evacuations as burning cargo ship spews toxic gas off Canada's coast

The Canadian coast guard has evacuated 16 people from a burning container ship that is expelling toxic gas off Canada's Pacific coast, but there is "no safety risk" to those on shore, authorities said Sunday.

The Zim Kingston is anchored off the city of Victoria in British Columbia, in the Strait of Juan de Fuca which marks the maritime border between Canada and the United States, according to the marine tracking site MarineTraffic.

It had been bound for Vancouver when the flames erupted, with the fire reported to the coast guard at around 11:00 pm local time Saturday, CBC News reported.

"The ship is on fire and expelling toxic gas," the Canadian coast guard said in a navigational warning on its website.

Later a statement on the coast guard's Twitter account said 16 people had been evacuated from the Zim Kingston "after a fire broke out in ten containers."

"The fire remains a dynamic event and an Incident Command Post has been set up to manage the situation, the statement early Sunday said, adding that responders were mobilising to fight the fire and recover containers that broke away from the ship Friday.

"Currently there is no safety risk to people on shore, however the situation will continue to be monitored," the tweet said.

On Sunday the Coast Guard said an emergency zone around the ship had been expanded to two nautical miles, up from one mile the day before.

"Due to the nature of chemicals onboard the container ship, applying water directly to the fire is not an option," it said, adding that a tugboat had instead sprayed cold water on the hull.

Later, however, the vessel's manager Danaos Shipping said in a statement that the incident was caused by "excessive listing due to extreme weather," and indicated the fire was contained.

"No injuries were reported. The fire appears to have been contained and DANAOS have commissioned a Salvage & Fire Extinguishing Agency to come on board in order to ensure that conditions are appropriate for the safe return of the vessel's crew," the company added.

The coast guard said the ship is carrying more than 52,000 kilograms (115,000 pounds) of chemicals located in two of the containers that are on fire, according to CBC News.

Regulator takes action against Nissan, Porsche over false emissions info

SEJONG, Oct. 24 (Yonhap) -- South Korea's antitrust regulator said Sunday it has decided to order Nissan Motor Corp., Porsche AG and their two Korean units to take corrective steps for falsified information over gas emissions of their diesel cars.

Nissan Motor, Nissan Korea, Porsche and Porsche Korea are alleged to have stated false information about gas emissions of their diesel vehicles imported for sale in South Korea, according to the Korea Fair Trade Commission (KFTC).

The KFTC also decided to impose a fine of 173 million won (US$146,700) only on Nissan Korea.

Illegal software installed in their cars caused gas emission reduction devices to not fully operate during normal driving conditions.

The practice meant that the cars did not meet permissible emission levels, but the automakers falsified such facts in signs attached to their cars, according to the commission.

In September, the regulator fined Audi-Volkswagen Korea and Stellantis Korea a combined 1.06 billion won for similar allegations over gas emissions.

Majority of 15–19-year-olds wanted COVID jab

Unconcerned for themselves — but willing to protect others. These attitudes were expressed by many teenagers on being asked whether they wanted to get vaccinated against COVID-19. The study, from the University of Gothenburg, shows that a majority were in favor of the idea.

The study, published in the scientific journal Vaccine: X, is based on questionnaire responses from 702 adolescents in Sweden, aged 15–19, between July and November 2020. The survey was thus carried out before the country’s vaccination program began.

The study was led by University of Gothenburg researchers in collaboration with colleagues at University West, Karolinska Institutet and Umeå University. The study participants came from various parts of Sweden, and the results are both qualitative and quantitative in nature.

The questionnaire survey results show that 54.3 percent were willing to be vaccinated, while 30.5 percent were undecided. Anxiety about getting vaccinated, which was more marked in girls than in boys, was a factor associated with reluctance to get vaccinated.

Many of the adolescent respondents stated that they had pondered the pros and cons of the COVID vaccine. Overall, their attitude was positive, while they said they needed to know more about it. In many cases, this perceived lack of knowledge was crucial to their decision.

Skepticism passed on from parents

One misgiving expressed was the rapid development and fast-tracking of the vaccine; here, respondents mentioned their worry about serious side effects. Some referred to the mass vaccinations against swine flu in 2009/10, when in some cases the vaccine caused narcolepsy.

This particular aspect took Stefan Nilsson by surprise. An associate professor and senior lecturer at the University’s Institute of Health and Care Sciences at Sahlgrenska Academy, Nilsson is the study’s first and corresponding author.

“They were small children when the swine flu vaccinations came along, so it must have been their parents or other elders who influenced them, or else they’ve read about it. Clearly, that experience of the swine flu vaccine influences the younger generation as well,” he says.

At the time of the data collection, there were no reports of COVID-related deaths among young people in Sweden. For their own part, moreover, many of the teenage respondents were unafraid of becoming infected and falling ill.

Wish to protect others

Many, on the other hand, voiced altruistic motives for getting vaccinated and thereby protecting others whose health was more fragile. A further indication that the adolescents were willing to get the jab for other people’s sake was that this attitude was found to be linked to the practice of social distancing.

“The results suggest what steps need taking to make it easier for young people to make an informed decision ahead of getting vaccinated. They need factual information that the risks of COVID’s adverse effects are greater than the risks of any side effects of the jab,” Nilsson says.

“And the information needs to be spread through information channels that reach adolescents. What’s more, it’s important for there to be discussion forums where the young can meet experts who can discuss and answer their questions.”

Russian scientists have created an express sensor to determine the toxicity of honey


Rapid prototype analyzer requires ultra-low amount of product

Russian scientists at Ural Federal University (UrFU, Yekaterinburg) and the Institute of Organic Synthesis, Ural Branch of the Russian Academy of Sciences have created an express sensor for the detection of nitrobenzene in food and cosmetics. In addition to requiring an ultra-small amount of material to analyze, the sensor also delivers unprecedented accuracy. It detects the presence of nitrobenzene, a dangerous toxin that can contaminate honey and other popular foods, in a matter of minutes. The description of the development was published in the Food Chemistry magazine.

Nitrobenzene is an extremely dangerous compound with a strong carcinogenic and mutagenic effect, which is difficult to chemically neutralize. It is widely used in the chemical industry as a solvent. Controlling the content of this substance in the food and the environment is an essential part of environmental monitoring. One of the foodstuffs most susceptible to nitrobenzene contamination is honey. This is caused by the use of insecticides used to protect bees and hives from ticks.

Most methods for determining the level of nitrobenzene in products require lengthy laboratory work and are therefore not suitable for quick on-site analysis. The development of portable analytical devices is of increasing practical interest, as the scientists of the Ural Federal University explained.

“The sensitivity and accuracy of such analyzers are determined by the structure of the "recognizer" - the so-called receptor layer. As a rule, it consists of enzymes, universal biological catalysts, which, along with some advantages, have a high cost and low chemical stability,” said the head of the research group, professor at UrFU Alisa Kozitsina.

University specialists have developed a synthetic receptor as a replacement for enzyme-based systems, and also created a prototype of a portable analyzer based on it. Its principle of operation is based on the use of organic compounds of the diazine class: these substances are able to selectively interact with nitrobenzene, "pulling" it out of the analyzed sample onto the electrode of the electrochemical sensor. According to the creators, the new method is distinguished by exceptional sensitivity and minimal labor costs for sample preparation.

“Unlike optical spectral analyzers currently used to search for nitrobenzene, electrochemical sensors are miniature, easy to manufacture, and require an ultra-small amount of the analyzed product. Our recognition system and the prototype of an electrochemical sensor have no direct analogs in the world,” said associate professor at UrFU Tatiana Svalova.

Using the new approach, the researchers were able to detect unsafe amounts of nitrobenzene in some commercial honey samples that were missed in the analysis of the accepted methods. An important advantage of the new method is the possibility of implementation both in stationary laboratories and in the form of portable devices. The development will be in demand not only in environmental monitoring and food quality control but also in industry, for example, in the production of cosmetics, scientists are sure.

The research team plans to make sensors universal and widespread. At the same time, they want to continue both fundamental research in this area and the development of new analytical systems for working with hazardous chemicals and drugs. 

The introduction of perennial plants among rainfed almond trees helps to mitigate climate change

Agriculture and the change in soil use produce 23% of the total emissions of greenhouse gases of anthropogenic origin. Moreover, the expansion and intensification of agriculture are considered determining factors in soil loss and degradation by accelerating erosion rates and favouring the loss of organic matter and nutrients.The most commonly used sustainable farming practices to maintain and restore the organic carbon in poor soils are reduced tilling; the use of plant covers; and the application of compost or manure, but how does crop diversification affect the carbon cycle? A team from the European Diverfarming project have analysed the potential of diversification in woody crops (almond and mandarin trees), determining that the introduction of perennial plants such as thyme and caper in rainfed almond trees favours the mitigation of climate change through the increase in soil carbon sequestration.

The team formed by the researchers form the CEBAS – CSIC María Martínez-Mena, Carolina Boix-Fayos, Efraín Carrillo, María Almagro,and Elvira Díaz,together with the researchers from theUniversidad Politécnica de Cartagena, Raúl Zornoza, Virginia Sánchez, José Antonio Acosta,and Silvia Martínez evaluated the short-term effect of the crop diversification on the soil carbon balance for a system of rainfed and of irrigated woody crops in semi-arid Mediterranean conditions. Specifically, they quantified the gains and losses of soil carbon to calculate the balance and evaluated the impacts of crop diversification on the main components that affect the carbon balance in two case studies of the Diverfarming project located in Murcia.

The crops assessed were organic rainfed almond trees and irrigated mandarin trees.In 2018, perennial crops such as capers and thyme were planted in the alleys of the almond trees, whilst in the alleys of the mandarin trees annual crops were introduced in rotation: a mix of barley, vetch and beans.The research team monitored the CO2 emissions to the atmosphere coming from the soil, as well as the carbon loss due to erosion and the carbon gains to the system by the growth of the plants,for two years.

Crop diversification affected the carbon balance (gains and losses) in the short term.Although in the irrigated mandarin crop diversified with annual plants the carbon soil carbon balance did not improve, the introduction of perennial species in the rainfed almonds did do so (reducing the carbon losses by between65 and 73%).

The potential of intercropping with perennial plants in woody systems to mitigate climate change through soil carbon sequestration could increase in the long term, once the new crops are fully developed and stabilised.Theongoing nature of the research would enable to confirm if this type of diversification would be a long-term solution to convert these systems into carbon sinks, thereby contributing to mitigating climate change.
