Abstract: One of the most devastating shocks to global security imaginable is a pandemic.
As history helps to demonstrate, this catastrophe and its reverberations could in
today's world create a scene not unlike that depicted in the Book of Revelation, when
the pale horse and its rider Death sow destruction “with sword and with famine and
with pestilence.” To protect our own interests and security, it is imperative that
the United States take preventive actions against a potential pandemic. This article
argues that one important area for mitigation is climate change interacting with the
growing urbanization of the world's population. These two factors combined promise
massive shocks to global security, and because of the destructive potential, it is
critical that U.S. national-security professionals consider this worst-case future
when developing policies and strategies. If a large-scale pandemic does occur, as
many scientists believe possible, are we prepared to handle it? Have we taken the
actions necessary to mitigate the worst-case outcome? This article also argues that
a lead actor in prevention efforts should be the U.S. military, which has the reach
and resources that others do not.
Biological threats—whether naturally occurring, accidental, or deliberate in origin—are
among the most serious threats facing the United States and the international community.

Much has been written about climate change and its causes and effects. While some
deny that climate change is happening or that humans have any mitigating role to play,4
most reasonable people would concede that climate change poses real problems that
must be addressed.5
Regardless of one's skepticism on the matter of climate change, it is essential to
consider its worst-case outcomes when developing U.S. security strategies and policies.
As the Department of Defense (DoD) has reported to Congress, “The effects of a changing
climate are a national security issue with potential impacts to [DoD] missions, operational
plans, and installations.”6
Of the projected negative effects of climate change, from severer storms to more extensive
droughts, probably the threat with the most devastating potential is a pandemic. From
disrupting trade to decimating populations, a pandemic could potentially cause more
destruction than a nuclear strike;7
thus, it is essential to understand how changing climate could unleash such destruction—with
little to no advance warning—and how we can best manage the consequences.
Most experts agree that the world is heading into a potentially severe warming phase,
with average temperatures expected to rise 2-6 degrees Celsius (C) by the end of this
century.8
As a result, weather events such as heat waves and storms, and the attendant consequences
of droughts and floods, are expected to increase in frequency and severity.9
And due to these climatic and weather changes, a significant increase is expected
in the potential for infectious diseases transmitted via insects, rodents, and contaminated
water.10
Deadly diseases carried by insects, such as malaria, thrive at higher temperatures
and so are expected to be a more active threat in the years ahead. In addition, waterborne
infectious diseases, such as cholera, will also likely increase due to poor sanitation
caused by water scarcity in times of drought and by “overwhelmed sewage lines or the
contamination of water by livestock” during times of flooding.11
As an example of how bad a cholera epidemic can become, consider the recent outbreak
in Yemen, which erupted in April 2017 and has since led to over one million suspected
cases and over 2,500 deaths.12
The ongoing civil war in Yemen and the resulting scarcity of water have exacerbated
the epidemic.13
A Deadly History
Pandemic disasters caused by climate change are not new; there are plenty of examples
in world history. One especially tragic example is the “Black Death” of the mid-fourteenth
century, which killed upwards of 75 million people in Europe and Asia and likely was
caused by climatic changes that stimulated the growth of the rodent population. Certainly,
this example involved a complex interaction of factors over an extended period of
decades. A mild climate in eastern Kazakhstan and southwest China “fostered plant-food
abundance and hence wild rodent proliferation.” As a subsequent cooling took place,
“plant growth declined” and catastrophic floods “displaced and drowned many people.”
The environmental changes “likely also displaced wild rodents and increased rodent-human
contact.” At the same time, in western China “encroaching nomadic Mongol pastoralists”
and “Han Chinese farmers” engaged in increased conflict, and this also displaced people
and likely increased rodent-human contact. This chain of climatic effects could well
have potentiated a deadly plague epidemic. “Before long, trade caravans or (more probably)
horse-borne Mongol armies, with ‘companion’ black rats, carried the disease westward
into Europe. .. via the Black Sea port of Kaffa.” Within ten years, Europe's population
was decimated.14
This pandemic starkly illustrates the dark side of fourteenth-century globalization.
It demonstrates all too clearly that climate changes in one location can result in
cascading effects that ripple around the world and eventually wreak havoc far removed
from the source of initial disaster. Those forces were the same ones that we face
today: natural disasters, migrations of people, conflict over scarce resources, and
ultimately a pandemic transmitted around the world through trade and war. At present,
with billions more people and modern means of transportation, it is clear the same
situation today would be exponentially more disastrous. Lest one think that modern
society is safer due to advanced technology and capabilities, consider that many experts
believe the opposite: modern societies, though better resourced and more interconnected,
are also more densely populated and infrastructure-dependent, and hence less flexible
and more vulnerable to a sudden disastrous shock.15
An Explosive Combination
One of the starkest differences between now and the mid-fourteenth century is how
populated the earth is at present, and how much of that population has crowded itself
into urban centers. The current world population is over 7.5 billion people, approximately
55 percent of whom live in urban environments.16
Compare that to a world population of approximately 450 million before the onset of
the “Black Death,” most of whom lived in rural, sparsely populated areas.17
Looking ahead, the trend to urbanization is only expected to continue: experts estimate
that roughly 68 percent of the population will live in dense urban environments by
the year 2050.18
While the movement of rural populations to cities is caused by several factors, including
economic and educational opportunities, it is being exacerbated by the increased incidence
of droughts, floods, and other consequences associated with climate change.19
These climate-related disasters hurt agricultural production and serve as “push” factors
from rural to urban, just as jobs and education serve as “pull” factors. Experts predict
that climate-induced migrations potentially will accelerate after 2050.20
Most of the urban growth is projected to occur in Asia and Africa, where developing
countries dominate the landscape21
and where basic healthcare, sanitation, and other infrastructure is sorely lacking
in rural areas.22
As a result, cities in developing countries that are already at, or near, the limits
of the population they can adequately support are being slowly overwhelmed by at-risk
migrants who are overtaxing already weak infrastructure and security systems. This
problem is exacerbated by the rapid development of megacities, defined as having a
population in excess of 10 million. “In 2017, developing nations boasted 26 megacities
compared to seven in developed countries.”23
This trend toward expansion in developing countries is set to continue, especially
in Africa. For example, Luanda, predicted to become a megacity by 2030, “is expected
to undergo a 60 percent increase in its population between 2017 and 2030, placing
further strain on housing, transport, public utilities and sanitation.”24
One critical problem with the expanding urban landscape is that the growth is largely
uncoordinated. Densely populated shanty towns and slums ring the edges of otherwise
modern and ordered square blocks of skyscrapers and malls.25
The uncontrolled development leads to increased human interaction with rats and other
rodents, thereby greatly increasing the likelihood of zoonotic infectious diseases.26
Also increasing the potential for zoonotic contagions is that the new populations
push cities out into previously undisturbed ecosystems (e.g., adjacent deserts and
forests), and as a result contact between animals and humans increases, generally
in unsanitary environments.27
The overcrowded conditions heighten the risk of vector-borne diseases, such as malaria
and dengue fever.28
Basic sanitation and water systems become overwhelmed, resulting in contaminated water
supplies and increasing the potential for cholera and other water-borne diseases.29
Diseases that were formerly confined to rural areas accompany the migrants into the
new urban environment, where they have a much greater chance to thrive.30
Security services are often unable to properly police the expanded slum areas, which
can become lawless and less secure. In addition, where order has disappeared, other
city services generally will not go. Most critically, existing healthcare services
cannot properly serve the increased population. If a pandemic takes root in such an
environment, chances are high that it will spread rapidly before it can be detected.
To understand how severe the problem can become, one can look at Mogadishu, Somalia.
Mogadishu's devastation has been caused by many factors, including poverty, violence,
and lack of effective governance.31
Climate change has been a significant contributor to all of this. As scholars Giovanna
Kuele and Ana Cristina Miola have noted, “Over the past decade climate change-related
desertification has expanded in Somalia, greatly increasing the vulnerability of the
local population.”32
This change has sharpened disputes over scarce water resources and has led to “high
rates of malnutrition, disease outbreaks, and food insecurity.” Cholera epidemics
have been recurrent in Somalia, the most recent one starting in late 2017, and thousands
have died as a result.33
With disease and violence rampant, over one million Somalis have been displaced; with
Mogadishu in utter chaos, many of them have migrated to nearby Kenya, thus putting
a strain on Kenya's resources.34
In the Yemen cholera outbreak noted above, scientists have determined that the strain
causing the outbreak “came from Eastern Africa and entered Yemen with the migration
of people in and out of the region.”35
Thus, it is likely that Somalia's dysfunction has contributed to Yemen's. Combined,
these problems have enabled easier recruitment of warlords, intent on controlling
the capital city Mogadishu through violence and terror.36
Mogadishu is the prime example of what Richard J. Norton has termed “feral cities,”37
where degradation and insecurity create conditions where disease and violence flourish.
An Aggressive Offense
Be Realistic. More aggressive action is required to resolve, or at least mitigate,
the immediate consequences and near-horizon disasters looming as a result of climate
change and increasing urbanization—especially regarding the possibility of a pandemic.38
Several arms of the U.S. government, including the Department of State (DoS), the
U.S. Agency for International Development (USAID), and the Centers for Disease Control
and Prevention (CDC), are actively combatting disease and climate change around the
world. However, none of these agencies can match the global presence39
and financial heft of DoD. This realization is especially true in the current political
environment, as the Trump administration seems intent on cutting foreign assistance
and health budgets while increasing DoD's. For example, President Trump's FY 2020
Budget “requests $718 billion for DOD, a $33 billion or five-percent increase from
the 2019 enacted level”; at the same time, it “requests $40.0 billion for the Department
of State and USAID, a $12.3 billion or 23-percent decrease from the 2019 estimate.”40
Congress is unlikely to agree with the president's overall budget proposal, now or
in the future, but it seems safe to predict that military resources will increase.
Due to its global reach and resources, the U.S. military is better placed than nearly
any other organization and should take an aggressive leading role in preventive efforts.
Unfortunately, to date, the international community has not demonstrated the will
to act decisively on climate change. While many nations voluntarily have signed onto
international agreements, such as the Kyoto Protocol and the Paris Agreement, few
of these countries adhere to the agreed standards.41
And, the agreed standards themselves have been called into question as not being sufficient.42
In addition, some of the greatest contributors to pollution and environmental degradation
flagrantly ignore climate concerns.43
Indeed, both India and China, two of the biggest polluters in the world, were exempted
from the Kyoto Protocol, and the Paris Agreement contains no formal enforcement mechanisms—one
of the glaring weaknesses of internationally engineered solutions to climate change.44
At the recent climate gathering in Katowice, Poland, participants agreed to a new
rulebook to improve the Paris Agreement; however, details of the “rulebook” are not
clear, and key countries did not support the creation of a global carbon market, seen
by many economists as the key to reducing carbon emissions worldwide.45
The gathering appeared to promise more of the same: heavy polluters will continue
to pollute, while certain developed countries will continue voluntarily to reduce
emissions (or not).46
This is not to say that international government organizations (IGOs) bring no benefit
to the discussion. The United Nations and other IGOs serve a useful role in raising
awareness, providing a forum for debate, and providing resources in some cases.47
For these reasons alone, the United States should stay actively involved in international
efforts to combat climate change and ensure as much as possible that U.S. interests
are promoted. However, a realist understands that due to the inefficiencies of international
consensus-building, IGOs’ actions generally will be longer-term solutions with slow
and clumsy implementation.48
As Divya Srikanth has written: “Developed states are highly reluctant to voluntarily
stunt their economic growth by adhering to the Kyoto Protocol, and developing states
are unwilling to compromise on their new-found economic successes. This has led to
a stalemate in terms of tackling the impact of climate change.”49
Though the stalemate shows no positive signs of breaking, due to the severity of the
stakes involved, America cannot abdicate leadership in this long-term effort. At the
same time, it must lead efforts to combat the near-term consequences of climate change.
Engage Partners, Including China. Fighting pandemics is one issue on which nations
should share strategic goals and could therefore use the opportunity to build better
relations.50
The United States should utilize this common interest and leverage alliances and partnerships
in the most at-risk locations.51
For example, one of the current hotspots for a future pandemic to break-out is Southeast
Asia, specifically the Sulu-Sulawesi Sea area. The U.S. military currently works closely
with Indonesia, Malaysia, and the Philippines—the countries that ring the Sulu-Sulawesi
Sea—on counterterrorism and anti-piracy actions in the area. These relationships could
be leveraged to take additional actions to prevent a pandemic from breaking out there,
such as increased coordination and construction of research, detection, and healthcare
facilities along the sea's edge.52
Even China, which has a significant interest in the Sulu-Sulawesi Sea and the adjacent
South China Sea,53
could be pulled into a multilateral partnership to fight against a pandemic.
There are multiple challenges to a U.S.-China partnership, including lack of trust
and a competition for influence, especially in Southeast Asia. As author Robert Kaplan
recently wrote, U.S-China differences are “stark and fundamental” and “can barely
be managed by negotiations and can never really be assuaged.”54
However, there are opportunities to exploit, one of which is China's experience dealing
with its own deadly disease outbreak in 2002-2004, when Severe Acute Respiratory Syndrome
(SARS) took root in Guangdong province and eventually infected over 8,000 people and
killed more than 900.55
According to one Chinese public health official, “The SARS crisis provided an enormous
boost to the development of China's public health system.”56
China is also considered by some to be a likely origin of a future pandemic, especially
from H7N9 bird flu, which Chinese and Western scientists have been studying closely
in hopes of preventing a disastrous spread.57
Presumably, China has significant knowledge and resources to contribute in the war
against pandemics. China also is keen to build roads, ports, and other facilities
as part of its Belt and Road Initiative (BRI),58
especially in developing regions such as Africa, and it has significant experience
managing the growth of megacities.59
Through effective partnering, China's infrastructure investments and its planning
experience could be harnessed toward mitigating the negative consequences of climate
change and urbanization.
To consider an indirect approach, China is realizing that its rapidly aging population
will not accommodate the country's current plan of sustained economic growth as a
means to sustain internal stability and increase global influence.60
As China envisions negative population growth as early as 2030,61
it will need to partner creatively with other countries and organizations to attain
the necessary prosperity to support its changed demographics.62
The United States should leverage China's changing domestic politics to pull it into
constructive partnerships on health and climate-change (and other) matters, and thereby,
it is hoped, increase its stake in an international rules-based order. This becomes
especially important as China seeks to build-up its navy and spread its influence.
As Bernard-Henri Levy has written, “One may hope, though without illusions, that China
will send its steel junks in the wake of the fleets of the wise Zheng He, China's
admiral of the western seas and leader of expeditions bound for glory and not for
conquest.”63
Active and constructive engagement on human-security problems is one way to help make
this happen.
Research and Model. One of the most effective defenses against a future pandemic is
to undertake research now in the hopes of discovering the potential pandemic before
it discovers us. Several governments and NGOs are actively engaged in this type of
research; however, they often lack adequate resources or cohesion to be truly effective.64
The U.S. military could fill a serious need by bringing its resources to bear. The
Naval Medical Research Unit (NAMRU) is an entity that the military could employ to
establish laboratory facilities to conduct research and support that of others, and
to help develop and maintain an organized database of useful information.65
USAID's Emerging Pandemic Threats program is one effort that this unit could support
more deeply,66
and an example of an effective component of this program is the PREDICT project, based
at the University of California, Davis.67
These organizations and others are researching contagions that potentially could infect
humans, especially from animal hosts, and possible vaccines to combat them. Researchers
perform their work in areas where contagions are most likely to take root, such as
the Sulu-Sulawesi Sea described above. It is areas like this where the U.S. military
should concentrate its efforts.
As part of its research, the U.S. military can engage in predictive modeling, trying
to determine based on weather patterns, people movements, socioeconomic factors, and
potential contagions—what this author collectively refers to as pandemic intelligence—where
the next pandemic might break out. An effective partner would be the National Oceanic
and Atmospheric Administration (NOAA), which has programs and technology in place
to monitor weather patterns and climate activity.68
The military could harness NOAA's capabilities and knowledge, and that of others,
to consider the potential cascade effects that would occur should a pandemic take
root and spread. As Chad Michael Briggs has noted, “Environmental systems often exhibit
feedback and multiplier effects, where a smaller change in one area leads to a cascade
of impacts with much greater shifts elsewhere.”69
For example, a 2010 heatwave in Russia caused a food shortage and price spikes in
North Africa and the Middle East and thus likely contributed to the Arab Spring revolts.70
Cascade predictions could help to predict both near- and long-term consequences and
would thus be critical in ensuring up-to-date Operational Plans to be used by the
military when responding to pandemic outbreaks, and for efforts to prevent or contain
outbreaks when responding to natural disasters.
Surveil and Detect. It is also critical to conduct surveillance of possible threats
from weather events, sudden migrations of people, and detected contagions.71
Many developing countries lack modern and reliable warning systems for incoming severe
storms. One of the reasons more than 1,200 people died when a tsunami hit Sulawesi,
Indonesia, in September 2018, was that the populations in its path were not properly
forewarned of the seriousness of the danger.72
The U.S. military should help to ensure that essential warning systems are in place
at critical spots, especially in Southeast Asia.73
In addition to working with local stakeholders to assess critical vulnerabilities,74
the military should coordinate with agencies such as NOAA, which has models and equipment
in place to warn of natural disasters. For example, NOAA has 39 tsunami detection
buoys placed throughout the world's oceans and seas, most heavily in the Pacific.75
However, despite these buoys and NOAA's predictive capabilities, Indonesia and other
countries continue to rely on their own systems, with oftentimes disastrous results.76
In Indonesia's case, its warning system was no longer operational in September 2018
due to lack of maintenance.77
Because of its worldwide presence and resulting unique relationships and influence,
the U.S. military is well-positioned to ensure coordination between developing countries
and U.S. agencies such as NOAA, who have capabilities to help but sometimes lack the
resources to effectively coordinate.
When natural disasters do occur, the U.S. military should maximize its strengths to
complement the work of other relief organizations. For example, drone and satellite
technology can monitor sudden migrations of people and detect infectious diseases
that might be accompanying a group. Scientists have experimented with using drones
to take samples of mosquitos and other potential carriers of disease, and this could
be an effective way to discover contagions before they hit a large city, or to determine
which parts of a city might be at risk once a contagion has taken root.78
In addition, drones could be used to deliver self-spreading vaccines and other countermeasures
to remote or highly infected locations.79
Drones and satellites could also be used to monitor at-risk environmental ecosystems.
Scientists are developing techniques to use these technologies to monitor the health
of crops,80
and the same ideas conceivably could be used to research the potential for zoonotic
diseases to take root, especially in areas where human-animal interactions are unexpectedly
increasing. The pandemic intelligence that results could be valuable not just for
local predicting, but also for the cascade modeling described above. Due to its reach
and resources, the U.S. military is ideally situated to assist in this type of research
and should work with the governments of at-risk nations, other U.S. government agencies,
and allies who share common interests in the at-risk areas.
Build Capacity and Change the Force
As cities greatly expand in the coming decades, many predict that only a small percentage
of them will be healthy and properly regulated; most will contain large areas of at-risk
populations, where a pandemic could easily take root and spread.81
Many cities in developing countries lack proper sanitation and sewage facilities and
have insufficient healthcare infrastructure.82
To help correct this, the U.S. military should increase its partnering of civil-affairs
and engineering resources with at-risk cities and development organizations to upgrade
and build necessary infrastructure.83
Because a significant reason for increasing urbanization is migration from rural areas,84
at-risk governments should take steps to improve rural infrastructure and services
as well. Again, the U.S. military has reach and resources that others cannot match.
It could expand ongoing efforts, such as the Pacific Environmental Security Forum,85
and make them more frequent and routine. It is essential to expand partnerships with
and support the World Health Organization (WHO), USAID, and others to add facilities,
provide training, conduct services in the most vulnerable areas, and help cities better
plan for expansion and a proper balance of interaction between humans, animals, and
delicate eco-systems.86
As noted earlier, an effective partner could be China, whose focus on public infrastructure
could be strengthened by America's traditional focus on policy reform and technical
assistance in sectors such as healthcare.87
The U.S. military should also upgrade its own capacity in line with the new threat
environment. While we place a renewed focus on great-power competition with China
and Russia and continue hedging against terrorism and other intermediate threats,
we should also factor in human-security challenges such as pandemics. Our force structure
should change to reflect this. For example, we should add more hospital ships and
invest more heavily in health-related Artificial Intelligence (AI) capabilities, even
if that means cutting warships. In addition to providing essential medical services,
the hospital ships could be redesigned and updated to include extensive laboratory
facilities and drone and AI platforms to assist with research, surveillance, and detection.88
The drones could also be used to deliver medical supplies to hard-to-reach locations.
Some would argue that this change in force structure would cut against the grain of
the National Defense Strategy's emphasis on traditional “lethality”89
and its focus on great-power competition,90
diverting money from much-needed warfighting capabilities. However, it is reasonable
to argue that the American homeland and overall global security face a deadlier threat
from a pandemic than from Chinese or Russian aggression. As an example, one should
consider the Spanish flu that broke out in 1918, and by the spring of 1919, it “had
sickened an estimated one-third of the world's population and may have killed as many
as 50 million people,”91
including approximately 675,000 Americans.92
This black swan attacked a world completely unprepared for it, and its death toll
was higher than that of the Great War that immediately preceded it.93
A more recent example is the swine flu pandemic of 2012, which, according to CDC,
killed an estimated 284,500 people.94
Security against this kind of non-traditional threat involves a different kind of
lethality, one in which we invest in capabilities that are designed to preempt and
destroy contagions rather than people and infrastructure. Adding hospital and laboratory
ships, and the associated drone and AI capabilities, would greatly improve our ability
to provide medical services and research and surveillance support at the most at-risk
locations. It would also demonstrate a positive U.S. presence to huge segments of
the developing world's population.95
From a budgetary perspective, consider that “the cost to the global economy of SARS
is estimated to have been $54 billion, according to the World Bank, while the organization
estimates that a ‘severe flu pandemic’ could cost over $3 trillion, nearly five percent
of global GDP.”96
Even if a newly designed hospital and laboratory ship carried a price tag of $2 billion
or so, the potential of catastrophic loss from a pandemic dwarfs the investment in
human security that would come with the procurement of a fleet of these ships.97
When one considers that the majority of the world's growing urban population resides
“in a coastal zone or a zone with distinct coastal influence,”98
the argument to update the Navy's human-security capabilities becomes even more cogent.
Moving Forward
As climate change and urbanization progress, pandemics are likely to occur, and American
national-security professionals must consider this worst-case scenario as they develop
strategies and policies. If we actively pursue preventive and mitigating actions,
the outcome of a pandemic could be a disaster that can be managed, contained, and
learned from. The alternative will be more Mogadishus, or worse. IGOs play an important
role in encouraging international debate and in providing limited resources; however,
to address the looming threat of deadly contagion, we must take aggressive and pragmatic
action. Due to its reach and resources, the U.S. military is well-placed to lead.
It should partner with governments and NGOs, leveraging existing alliances and building
new ones. Primary actions should include conducting research and creative predictive
modeling; ensuring effective surveillance and detection efforts; and upgrading and
building infrastructure in high-risk areas. The military should also revise its capabilities
to better address the growing pandemic threat.
It is appropriate to close with an overarching statement of purpose from the U.S.
National Biodefense Strategy: “The United States will use all appropriate means to
assess, understand, prevent, prepare for, respond to, and recover from biological
incidents—whatever their origin—that threaten national or economic security.”99
Due to the interconnectedness of today's world, it is hard to imagine a pandemic that
would not have potential to threaten American security. We must approach the fight
against pandemics aggressively, detecting, containing, and destroying a pandemic when
it attacks, and the rest of the time working to prevent and prepare for the next pandemic.100
As the climate warms and eco-systems change, new and deadlier contagions will enter
the fight, and we must stay engaged.101
