At the Union of Concerned Scientists, we have long advocated agricultural systems that are productive and better for the environment, the economy, farmers, farmworkers and eaters than the dominant industrial system. We refer to such a system as our Healthy Farm vision. Based on comprehensive science, we have specified that healthy farm systems must be multifunctional, biodiverse, interconnected and regenerative.


The scientific case for agricultural systems that renew rather than diminish resources is comprehensive, and research demonstrates the productivity and agronomic feasibility of such systems. Yet, economically viable real-world examples are necessary to spur acceptance and adoption of such schemes. Further, we need to overcome the limitations of economic thinking and measures that were developed in the 19th century—when it seemed that the earth's resources and its capacity to absorb waste were inexhaustible—and improve them to create more modern assessments, appropriate for the 21st century and beyond. A new report from our colleagues at Farmland LP, Delta Institute and Earth Economics will make a major contribution toward this end.

Our World In Data

Economists view agriculture as a primary sector of the economy, meaning that without the activity of that sector, the remainder of the economy (such as manufacturing and service) could not be developed. Together with other primary economic enterprises such as mining and forestry, agriculture has generally been practiced and acknowledged as an extractive industry. Whereas mining is visibly extractive, agriculture is less so, because degradative processes such as soil erosion, fertility loss, and water and air pollution are not as obvious as mountaintop removal and strip mining. Yet, as practiced industrially, agriculture is both extractive and more extensive than mining.

Extractive agricultural practices are abetted by strategies such as importing nutrients to compensate for loss of native soil fertility and by the fact that we value the gains from the extraction but don't discount the losses. For example, we measure crop and animal yield and translate that to sales and profit, but don't subtract from the ledger the soil, nutrients, air and water quality lost to produce crops and livestock. One superficial reason for this is that we don't know the "cost" of those resources, but that is simply a polite way to say that historically we don't value them. This is a perfect example of the nostrum that we measure what we care about and care about what we measure.

Yet, agriculture need not be inherently extractive. Through practices that build soil, recycle nutrients and store water it can become a regenerative system while still providing abundant food and other agricultural products. A key to shift from extractive to regenerative mode is to build a more complete picture of the total benefits and costs associated with agricultural management. For nearly a decade, the investment firm Farmland LP has been managing thousands of acres with regenerative techniques, thereby providing an opportunity for scientists and economists to assess the value of these practices to soil, water, climate, energy and social sectors. The Delta Institute and Earth Economics, with grant support from the Department of Agriculture's Natural Resources Conservation Service, worked with Farmland LP on just such a project.

Based on a comprehensive review of scientific literature examining the value of various ecosystem services, the researchers applied the rigorous methodologies of Ecosystem Services Valuation and Greenhouse Gas Accounting to assess the effects of farm management on items such as soil formation and quality, water capture and quality, pollination and seed dispersal, climate stability, disaster risk reduction, air quality and biological control. Using Colorado State University's COMET-Farm model, and the USDA's Revised Universal Soil Los Equation, the researchers evaluated the effect of regenerative techniques on farmed and non-farmed land under Farmland LP's management. They compared these model outputs with those from land managed conventionally to construct a comprehensive impact balance sheet.

The sums cited in this report are astounding, ascending into the millions of dollars of added ecological value from regenerative process—against millions of dollars of ecological losses due to standard industrial practices. The practices Farmland LP implements are well-known, backed by science and practice, and accessible to all farmers and farm managers with an interest in managing whole systems to increase returns to management. Examples include integrated crop and livestock production, crop rotation, biodiverse annual and perennial mixes, stream buffers, grassed waterways, organic fertilizers, biological pest control and uncultivated land to provide ecological services (erosion control, water capture, habitat and refugia for beneficial organisms.) The combination of these regenerative methods generated net value while industrial methods destroyed value—all while performing comparably on the dominant indicator of agricultural yield.

This assessment affirms the concrete value and effectiveness of multifunctional regenerative approaches. Since many of these ecosystem services are not currently quantified—much less traded—on markets that would remunerate farmers, the benefits are primarily experienced by way of cleaner environment, lower costs of production and added value of agricultural land. This is because land managed with regenerative practices will produce bountifully, at lower cost and for an indeterminate period of time, whereas the value of industrially managed land depends on false and brittle economies, such as access to government subsidies and the availability of cheap industrial fertilizer.

In fact, the main business of Farmland LP, a real estate investment trust, is to add long-term value to agricultural land for landowners and investors. A remarkable aspect of this strategy and business model, in addition to more faithfully reflecting actual ecological economics, is how quickly Farmland LP management has been able to produce results. In addition to demonstrating the effectiveness of regenerative methods, these findings indicate the kinds of practices that should be more broadly adopted across all of agriculture to assure our livelihood at present and far into the future.

The skilled agronomists and farm managers at Farmland LP, together with the rigorous scientists and economists who have developed and used the ecosystem evaluation technique, are demonstrating that regenerative agriculture is not an aspirational figment. It is real, it is possible, it is productive, it is profitable and it is environmentally beneficial. These things can all exist with one another. A successful business model is predicated on this. As long as reliable scientific information influences decisions and behavior, this report provides a beacon toward more viable, ethical and realistic agricultural practice for the long term.

On Monday and Tuesday of the week that President Donald Trump held his first rally since March in Tulsa, Oklahoma, the county reported 76 and 96 new coronavirus cases respectively, according to POLITICO. This week, the county broke its new case record Monday with 261 cases and reported a further 206 cases on Tuesday. Now, Tulsa's top public health official thinks the rally and counterprotest "likely contributed" to the surge.

As we look for advanced technology to replace our dependence on fossil fuels and to rid the oceans of plastic, one solution to the climate crisis might simply be found in rocks. New research found that dispersing rock dust over farmland could suck billions of tons of carbon dioxide from the air every year, according to the first detailed large scale analysis of the technique, as The Guardian reported.

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Niq Steele / Getty Images

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.

When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.

We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.

Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.

What Is Guillain-Barre Syndrome?

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.

Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.

To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.

Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.

The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.

Guillain-Barre Syndrome and Pandemics

As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.

Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.

Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.

The first reports of Guillain-Barre Syndrome in COVID-19 pandemic originated from Italy, Spain and China, where the pandemic surged before the U.S. crisis.

Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?

The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.

Understanding the Association Between COVID-19 and Guillain-Barre Syndrome

While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.

It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.

Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.

Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

Democratic presidential hopefuls Joe Biden and Senator Bernie Sanders greet each other with a safe elbow bump before the start of the Democratic Party 2020 presidential debate in a CNN Washington Bureau studio in Washington, DC on March 15, 2020. Mandel Ngan / AFP / Getty Images

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.

"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."

The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."

In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."

"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."

 

The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.

Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."

"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."

Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."

"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.

On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.

Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.

"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.

Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."

 

Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."

Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."

"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."

"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
