One of the greatest challenges in monitoring food security is to provide reliable crop yield information that is temporally consistent and spatially scalable. An ideal yield dataset would not only extend globally and across multiple years, but would also have enough spatial granularity to characterize productivity at the field and subfield level. Rapid increases in satellite data acquisition and platforms such as Google Earth Engine that can efficiently access and process vast archives of new and historical data offer an opportunity to map yields globally, but require efficient and robust algorithms to combine various data streams into yield estimates. We recently introduced a Scalable satellite-based Crop Yield Mapper (SCYM) that combines crop models simulations with imagery and weather data to generate 30 m resolution yield estimates without the need for ground calibration. In this study, we tested new large-scale implementations of SCYM, focusing on three regions with varying crops, field sizes and landscape heterogeneity: maize in the U.S. corn belt (390,000 km2), maize in Southern Zambia (86,000 km2), and wheat in northern India (450,000 km2). As a benchmark, we also tested a simpler empirical approach (PEAKVI) that relates yield to the peak value of a time series of spatially aggregated vegetation indices, similar to methods used in current operational monitoring. Both SCYM and PEAKVI were applied to data from all Landsat's sensors and MODIS for more than a decade in each region, and evaluated against ground-based estimates at the finest available administrative level (e.g., counties in the U.S.). We found consistently high correlations (R2 ≥ 0.5) between the spatial pattern of ground- and satellite-based estimates in both U.S. maize and India wheat, with small differences between methods and source of satellite data. In the U.S., SCYM outperformed PEAKVI in tracking temporal yield variations, likely owing to its explicit consideration of weather. In India, both methods failed to track temporal yield changes, with various possible explanations discussed. In Zambia, the PEAKVI approach applied to MODIS tracked yield variations much better (R2 > 0.5) than any other yield estimate, likely because the frequent cloud cover in this region confounds the other approaches. Overall, this study demonstrates successful approaches to yield estimation in each region, and illustrates the importance of distinguishing between accuracy for spatial and temporal variation. The 30 m resolution of Landsat-based SCYM does not appear to offer large benefits for tracking aggregate yields, but enables finer scale analyses than possible with the other approaches.

When one thinks of the casualties of war, it is easy to imagine severed limbs, bullet holes, shrapnel, perhaps even sarin gas or Agent Orange. But in a recent Daedalus essay, Paul Wise argues that the most damaging health impacts of war are often indirect. Losing access to food supplies, medication and electricity can kill more people than battle itself. In this video by the American Academy of Arts and Sciences, Wise, a professor of pediatrics and Stanford Health Policy core faculty member, explains how fatal the indirect costs of war can be.

While the United States has no peers in conventional military power, it is especially vulnerable – as a free and democratic society – to cyber misinformation campaigns, a Stanford scholar says.

Herbert Lin, a senior research scholar for cyberpolicy and security at Stanford’s Center for International Security and Cooperation (CISAC), is the co-author of a new draft working paper that spells out the perilous risks facing democratic, wired-up countries around the world.

America’s adversaries are seeking “asymmetric” methods for social disruption, rather than direct military conflict, Lin said.

“Cyber warfare is one asymmetric counter to Western (and especially U.S.) military advantages that depend on the use of cyberspace,” wrote Lin and his co-author Jackie Kerr, a research fellow at the Lawrence Livermore National Laboratory.

This new type of cyber aggression is aimed at winning – and confusing – hearts and minds, the very control centers of human existence, Lin said.

As a result, “information/influence warfare and manipulation,” or IIWAM as Lin describes it, poses profound implications for Western democracies, even though much of it may not be illegal under international law. This approach is based on the deliberate use of information by one party on an adversary to confuse, mislead, and ultimately to influence the choices and decisions that the adversary makes.

A recent example in point would be the 2016 Russian hacking of the U.S. presidential election and the surge of so-called “fake news.”

Lin points out that while misinformation campaigns are not new, the technology to spread it far and wide globally is. He noted that the patron saint of distorting reality for war-like purposes is Sun Tzu, who wrote that, “The supreme art of war is to subdue the enemy without fighting.”

While traditional cyber attacks typically hit hard targets like computer systems, cyber “influence” campaigns are conducted over longer periods of time and rely on soft power – propaganda, persuasion, culture, social forces, confusion and deception, Lin said. 

Words and images

How does it work? Lin explains:

“Victory is achieved by A when A succeeds changing B’s political goals so that they are aligned with those of A.  But such alignment is not the result of B’s 'capitulation' or B’s loss of the ability to resist – on the contrary, B (the losing side) is openly willing.”  That is, such victory shares the focus on subverting the opponent’s will, though not on destroying his military forces.

The ammunition in these cyberspace battles are “words and images,” the kind that persuade, inform, mislead, and deceive so that the adversary cannot respond militarily. In the example of a “fake news” story, they often take place below legal thresholds of “use of force” or “armed attack,” and at least in an international legal sense, do not trigger a military response.

The target is the “adversary’s perceptions,” which reside in the “cognitive dimension of the information environment.” In other words, such cyber warfare focuses on “damaging knowledge, truth, and confidence, rather than physical or digital artifacts,” according to Lin. It is the “brain-space.”

Additionally, IIWAM injects fear, anger, anxiety, uncertainty, and doubt into the adversary’s decision making processes, he added.  Success is defined as altering such perceptions so the target makes choices favoring the aggressor.

“Sowing chaos and confusion is thus essentially operational preparation of the information battlefield – shaping actions that make the information environment more favorable for actual operations should they become necessary,” the researchers wrote.

These cyber manipulations often prey upon cognitive and emotional biases present in the psychological and mental makeup of human beings, Lin said. 

For example, media channels such as Fox News play to “confirmation bias” for individuals with a right-of-center orientation, and similarly for MSNBC for those with a left-of-center, orientation, he wrote. Confirmation bias is the tendency to interpret new evidence as confirmation of one's existing beliefs or theories.

Countering misinformation

“Naming and shaming” is probably ineffective against many nation states conducting cyber disinformation campaigns, Lin said. And the idea that a government like the U.S. can quickly respond to misinformation created in the private sphere is unlikely to be effective as well.

What, then, might work? Lin suggests new tactics are needed, as no existing approach seems adequate. For example, Facebook is deploying a new protocol for its users to flag questionable news sites.  Google has banned fake news web sites from using its online advertising service. Twitter, YouTube, and Facebook shut down accounts that they determine are promoting terrorist content.  He noted that a recent Facebook letter from CEO Mark Zuckerberg states that, “Our approach will focus less on banning misinformation and more on surfacing additional perspectives and information, including that fact checkers dispute an item's accuracy.”

But such measures are unlikely to stem the “rising tide of misinformation conveyed” through cyber warfare, Lin said, because they mostly require users to do additional mental work.  

Wired world riskier

Today’s Internet-driven Western world offers countless opportunities for cyber influence mischief, Lin wrote.

“Democracy has rested on an underlying foundation of an enlightened, informed populace engaging in rational debate and argument to sort out truth from fiction and half-truth in an attempt to produce the best possible policy and political outcomes,” Lin wrote.

Cyber manipulators have exploited an arguable gap between ideals and reality in democratic systems – “rendered it much more questionable” – through the tremendous reach and speed of misinformation, he said. Many countries cannot deal with the onslaught of such focused efforts. This serves to make the democratic process look weak and unstable in the eyes of its citizens. The same dynamic does not apply equally around the world.

“Cyber weapons pose a greater threat to nations that are more advanced users of information technology than to less-developed nations,” Lin wrote.

He said that less developed or authoritarian countries do not have much Internet infrastructure or that wield control over expression – North Korea is an example.

Pandemics are a growing health concern in the United States and abroad. But as global health specialists are ramping up efforts to prevent them, funding may be slipping away.

President Trump's proposed budget would eliminate the National Institutes of Health's Fogarty International Center, a key player in the fight against diseases worldwide.

According to a USA Today column by Michele Barry, Director of the Center for Innovation in Global Health and a Stanford Health Policy affiliate, and David Yach, a former cabinet director at the World Health Organization, Fogarty's global health research benefits the United States along with other countries. The center has produced insights into Alzheimer's research, is looking into the genetics of obesity and diabetes, and has started developing early warning systems for pandemics.

But its most important accomplishment, according to Barry and Yach, is training scientists in more than 100 low- and middle-income countries. These experts have emerged as leaders in their own countries and around the world.

Their contributions have not only improved health but have influenced the World Health Organization and leading global health donors.

Said Barry and Yach, "To eliminate the Fogarty Center now would undermine progress, erode trust in America’s leadership in global health, and increase the risk of a devastating and preventable epidemic in the U.S. Keeping Fogarty would preserve health, both of Americans and populations all over the world."

When a state is “shamed” by outsiders for perceived injustices, it often proves counterproductive, resulting in worse behavior and civil rights violations, a Stanford researcher has found.

Rochelle Terman, a political scientist and postdoctoral fellow at Stanford’s Center for International Security and Cooperation (CISAC), recently spoke about how countries criticized by outsiders on issues like human rights typically respond -- and it's contrary to conventional wisdom. Terman has published findings, “The Relational Politics of Shame: Evidence from the Universal Periodic Review,” on this topic in the Review of International Organizations. She discussed her research in the interview below:

What does your research show about state "shaming"?

Shaming is a ubiquitous strategy to promote international human rights. A key contention in the literature on international norms is that transnational advocacy networks can pressure states into adopting international norms by shaming them – condemning violations and urging reform. The idea is that shaming undermines a state’s legitimacy, which then incentivizes elites into complying with international norms.

In contrast, my work shows that shaming can be counterproductive, encouraging leaders in the target state to persist or “double down” on violations. That is because shaming is seen as illegitimate foreign intervention that threatens a state’s sovereignty and independence.  When viewed in this light, leaders are rewarded for standing up to such pressure and defending the nation against perceived domination. Meanwhile, leaders who “give in” have their political legitimacy undermined at home. The result is that violations tend to persist or even exacerbate.

When and where does it work better to directly confront a country’s leadership about such injustices?

At least two factors moderate the effects of international shaming. The first is the degree to which the norm being promoted is shared between the “shamer” and the target. For instance, the West may shame Uganda or Nigeria for violating LGBT rights. But if Uganda and Nigeria do not accept the “LGBT rights” norm, and refuse to accept that homophobia constitutes bad behavior, then shaming will fail. In this case, it is more likely that shaming will be viewed as illegitimate meddling by foreign powers, and will be met with indignation and defiance.

Second, shaming is quintessentially a relational process. Insofar as it is successful, shaming persuades actors to voluntary change their behavior in order to maintain valued social relationships. In the absence of such relationship, shaming will fail. This is especially so when pressure emanates from a current or historical geopolitical adversary. In this later scenario, not only will shaming fail to work, it will likely provoke defensive hostility and defiance, having a counterproductive effect.

Combing these insights, we can say that shaming is most likely to work under two conditions: when the target is a strong ally, and the norm is shared.

What are some well-known cases where "shaming" backfired?

The main example I use in my forthcoming paper is on the infamous “anti-homosexuality bill” in Uganda. When Uganda introduced the legislation in 2009 (which in some versions applied capital punishment to offenders) it provoked harsh condemnation among its foreign allies, especially in the West. Western donor countries even suspended aid in attempt to push Yoweri Musaveni’s government to abandon the bill. According to conventional accounts, the onslaught of foreign shaming, coupled with the threat of aid cuts and other material sanctions, should have worked best in the Uganda case.

And yet what we saw was the opposite. The wave of international attention provoked an outraged and defiant reaction among the Ugandan population, turning the bill into a symbol of national sovereignty and self-determination in the face of abusive Western bullying. This reaction energized Ugandan elites to champion the bill in order to reap the political rewards at home. Indeed, the bill was the first to pass unanimously in the Ugandan legislature since the end of military rule in 1999. Museveni – who by all accounts preferred a more moderate solution to the crisis – was backed into a corner.

A Foreign Policy story quoted Ugandan journalist Andrew Mwenda as saying, “the mere fact that Obama threatened Museveni publicly is the very reason he chose to go ahead and sign the bill.” And Museveni did so in a particularly defiant fashion, “with the full witness of the international media to demonstrate Uganda’s independence in the face of Western pressure and provocation.”

Uganda anti-homosexuality law was finally quashed by its constitutional court, which ruled the act invalid because it was not passed with the required quorum. By dismissing the law on procedural grounds, Museveni – widely thought to have control over the court – was able to kill the legislation “without appearing to cave in to foreign pressure.” But by that time, defiance had already transformed Uganda’s normative order, entrenching homophobia into its national identity.

Does this 'doubling down' effect vary in domestic or international contexts?

Probably. States with a significant populist contingent, for instance, are especially hostile to international pressure, especially when it emanates from a historical adversary, like a former colonial power. Ironically, democracies may also be more susceptible to defiance, because elites are more beholden to their constituents, and thus are less able to “give in” to foreign pressure without undermining their own political power. 

The international context matters a great deal as well. States are more likely to resist certain norms if they have allies who feel the same way. For instance, we see significant polarization around LGBT rights at the international level, with most states in Africa and the Muslim world voting against resolutions that push LGBT rights forward. South Africa – originally a pioneer for LGBT rights – has changed its position following criticism from its regional neighbors. 

Does elite reaction drive this response to state "shaming?"

To be quite honest, this is a question I’m still exploring and I don’t have a very clear answer. My hunch at the moment is no. The “defiant” reaction occurs mainly at the level of public audiences, which then incentives elites to violate norms for political gain.  These audiences can be at either the domestic or international level. For instance, if domestic constituents are indignant by foreign shaming, elites are incentivized to “double down,” or at least remain silent, lest they undermine their own political legitimacy.

That said, elites can also strategize and manipulate these expected public reactions for their own political purposes. For instance, if Vladimir Putin knows that the Russian public will grow indignant following Western shaming, he might strategically promote a law that he knows will provoke such a reaction in order to benefit from the ensuing conflict. This is what likely occurred with Russia’s “anti-gay propaganda” law, which (unsurprisingly) provoked harsh condemnation from the West and probably bolstered Putin’s domestic popularity.

Any other important points to highlight?

One important point I’d like to highlight is the long-term effects of defiance. In an effort to resist international pressure, states take action that, in the long term, work to internalize oppositional norms in their national identity. In this way, shaming actually produces deviance, not the other way around.

Abstract:

One policy option for countries reliant on natural resources is to share part of the revenues directly with citizens, an idea known as oil to cash. Technological innovation, such as biometric identification and mobile money, now allow direct payments to people on a massive scale. Additional changes in the global marketplace, experiments in India and Kenya, and shifting political views of cash transfers have all affected the potential of cash to boost governance.

Whether it’s WikiLeaks and CIA documents or nuclear thieves, the danger from insiders in high-security organizations is escalating in our Internet age.

But many threats from within go unrecognized or misunderstood, according to Stanford professor Scott Sagan, who co-edited a new book Insider Threats with Matthew Bunn, a professor of practice at Harvard University. Their work analyzes the challenges that high-security organizations face in protecting themselves from employees who might betray them. Sagan, a core faculty member in Stanford's Center for International Security and Cooperation, and Bunn recently participated in an online discussion of the book’s key arguments. They will hold a talk and book signing at 3:30 p.m. on May 16 in the CISAC Central Conference Room.

Sagan and Bunn wrote, “Perhaps the most striking lesson we learned in working with scholars and officials who have dealt with this problem was the sheer scale of the red flags – from explicit statements of support for Osama bin Laden to behavior leading other staff to fear for their lives – that organizations are able to ignore.”

They found that organizations tend to have biases that cause them to downplay insider threats. In particular, organizations with high-security needs face significant risks from trusted employees with access to sensitive information, facilities, and materials. 

The researchers highlight "worst practices" from these past mistakes, suggesting lessons and insights that could improve the security situations at many workplaces. Amy Zegart, co-director of CISAC, has a chapter in Insider Threats that provides a detailed account of the organizational dysfunction that allowed Nidal Hasan to carry out his massacre at Fort Hood.

Other chapters include the following topics and authors:

  • An analysis of the similar problems that led Bruce Ivins, who probably carried out the anthrax attacks in 2001, to continue to have access to deadly pathogens (by Jessica Stern, then of Harvard and now at Boston University, and Ron Schouten, of Massachusetts General Hospital and Harvard Medical School);
  • An analysis of the rapid rise and subsequent fall of “green-on-blue” attacks in Afghanistan – that is, Afghan soldiers and police officers attacking Americans there to help them (by Austin Long of Columbia University); and 
  • An assessment of how casinos and pharmaceutical plants, with a profit incentive to protect against insiders, cope with the problem (by Bunn and Kathryn Glynn, then of IBM Global Business Services and now at the National Nuclear Security Administration). 

Another chapter examines the potential terrorist use of nuclear insiders, offering new data that shows that jihadist writings and postings contain only a modest emphasis on possible nuclear plots, and essentially no mention of the possibility of using nuclear insiders. However, the authors warn this is no reason for complacency – insiders have been largely responsible for past nuclear theft incidents.
