How Climate Change and Wars Are Increasing World Hunger
By Leah Samberg
Around the globe, about 815 million people—11 percent of the world's population—went hungry in 2016, according to the latest data from the United Nations. This was the first increase in more than 15 years.
Between 1990 and 2015, due largely to a set of sweeping initiatives by the global community, the proportion of undernourished people in the world was cut in half. In 2015, UN member countries adopted the Sustainable Development Goals, which doubled down on this success by setting out to end hunger entirely by 2030. But a recent UN report shows that, after years of decline, hunger is on the rise again.
As evidenced by nonstop news coverage of floods, fires, refugees and violence, our planet has become a more unstable and less predictable place over the past few years. As these disasters compete for our attention, they make it harder for people in poor, marginalized and war-torn regions to access adequate food.
I study decisions that smallholder farmers and pastoralists, or livestock herders, make about their crops, animals and land. These choices are limited by lack of access to services, markets or credit; by poor governance or inappropriate policies; and by ethnic, gender and educational barriers. As a result, there is often little they can do to maintain secure or sustainable food production in the face of crises.
The new UN report shows that to reduce and ultimately eliminate hunger, simply making agriculture more productive will not be enough. It also is essential to increase the options available to rural populations in an uncertain world.
Conflict and climate change threaten rural livelihoods
Around the world, social and political instability are on the rise. Since 2010, state-based conflict has increased by 60 percent and armed conflict within countries has increased by 125 percent. More than half of the food-insecure people identified in the UN report (489 million out of 815 million) live in countries with ongoing violence. More than three-quarters of the world's chronically malnourished children (122 million of 155 million) live in conflict-affected regions.
At the same time, these regions are experiencing increasingly powerful storms, more frequent and persistent drought and more variable rainfall associated with global climate change. These trends are not unrelated. Conflict-torn communities are more vulnerable to climate-related disasters, and crop or livestock failure due to climate can contribute to social unrest.
War hits farmers especially hard. Conflict can evict them from their land, destroy crops and livestock, prevent them from acquiring seed and fertilizer or selling their produce, restrict their access to water and forage, and disrupt planting or harvest cycles. Many conflicts play out in rural areas characterized by smallholder agriculture or pastoralism. These small-scale farmers are some of the most vulnerable people on the planet. Supporting them is one of the UN's key strategies for reaching its food security targets.

Disrupted and displaced
Without other options to feed themselves, farmers and pastoralists in crisis may be forced to leave their land and communities. Migration is one of the most visible coping mechanisms for rural populations who face conflict or climate-related disasters.
Globally, the number of refugees and internally displaced persons doubled between 2007 and 2016. Of the estimated 64 million people who are currently displaced, more than 15 million are linked to one of the world's most severe conflict-related food crises in Syria, Yemen, Iraq, South Sudan, Nigeria and Somalia.
While migrating is uncertain and difficult, those with the fewest resources may not even have that option. New research by my colleagues at the University of Minnesota shows that the most vulnerable populations may be "trapped" in place, without the resources to migrate.
Displacement due to climate disasters also feeds conflict. Drought-induced migration in Syria, for example, has been linked to the conflict there, and many militants in Nigeria have been identified as farmers displaced by drought.

Supporting rural communities
To reduce world hunger in the long term, rural populations need sustainable ways to support themselves in the face of crisis. This means investing in strategies to support rural livelihoods that are resilient, diverse and interconnected.
Many large-scale food security initiatives supply farmers with improved crop and livestock varieties, plus fertilizer and other necessary inputs. This approach is crucial, but can lead farmers to focus most or all of their resources on growing more productive maize, wheat or rice. Specializing in this way increases risk. If farmers cannot plant seed on time or obtain fertilizers, or if rains fail, they have little to fall back on.
Increasingly, agricultural research and development agencies, NGOs and aid programs are working to help farmers maintain traditionally diverse farms by providing financial, agronomic and policy support for production and marketing of native crop and livestock species. Growing many different locally adapted crops provides for a range of nutritional needs and reduces farmers' risk from variability in weather, inputs or timing.
While investing in agriculture is viewed as the way forward in many developing regions, equally important is the ability of farmers to diversify their livelihood strategies beyond the farm. Income from off-farm employment can buffer farmers against crop failure or livestock loss, and is a key component of food security for many agricultural households.
Training, education and literacy programs allow rural people to access a greater range of income and information sources. This is especially true for women, who are often more vulnerable to food insecurity than men.

Conflict also tears apart rural communities, breaking down traditional social structures. These networks and relationships facilitate exchanges of information, goods and services, help protect natural resources, and provide insurance and buffering mechanisms.
In many places, one of the best ways to bolster food security is by helping farmers connect to both traditional and innovative social networks, through which they can pool resources, store food, seed and inputs and make investments. Mobile phones enable farmers to get information on weather and market prices, work cooperatively with other producers and buyers and obtain aid, agricultural extension or veterinary services. Leveraging multiple forms of connectivity is a central strategy for supporting resilient livelihoods.
In the past two decades the world has come together to fight hunger. This effort has produced innovations in agriculture, technology and knowledge transfer. Now, however, the compounding crises of violent conflict and a changing climate show that this approach is not enough. In the planet's most vulnerable places, food security depends not just on making agriculture more productive, but also on making rural livelihoods diverse, interconnected and adaptable.

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.
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.

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."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
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."
