The ocean could produce up to 75 percent more seafood than it does today and drive sustainable economic growth, holding a key role in solving global hunger. Center on Ocean Solutions Co-Director Jim Leape joined Stanford Earth Professor Roz Naylor for a conversation about food security, the current COVID-19 pandemic and how global food policies can better integrate “blue foods” from marine and freshwater systems. 

"COVID-19 is disrupting processed and widely traded seafood products, such as salmon, shrimp and tuna," states Naylor. "However, locally produced and consumed food systems are actually faring much better. This is especially true for some small-scale fisheries, where local fishing groups have taken the initiative to sell seafood locally and new markets are emerging during the COVID-19 period. Production and consumption have become more tightly connected as a result."

Both Leape and Naylor are part of the global Blue Food Assessment, the first comprehensive review of aquatic foods and their roles in the global food system. Naylor will discuss the assessment with collaborators during the Virtual Ocean Dialogues on June 3rd. 

The pair also highlighted promising innovations for sustainable future food systems. "Illegal fishing defeats efforts to manage the resource sustainability and cheats the fishers who are playing by the rules," Leape explains. "And we can end it. Emerging technologies are bringing much greater transparency into the fishing industry."

"If we want healthy oceans in the future, we have to be thinking about a wide range of innovations, and the institutions, financial incentives, and public trust needed to turn these innovations into real market solutions," says Naylor.

COVID-19, combined with the effects of ongoing civil conflicts, hotter and drier weather in many areas, and an unfolding locust invasion in Africa and the Middle East, could cut off access to food for tens of millions of people. The world is “on the brink of a hunger pandemic,” according to World Food Program (WFP) Executive Director David Beasley, who warned the United Nations Security Council recently of the urgent need for action to avert “multiple famines of biblical proportions.”

(Watch Beasley’s conversation on food insecurity as a national security threat with his WFP predecessor, Ertharin Cousin, a visiting scholar with Stanford’s Center of Food Security and the Environment.)

Understanding how these conditions – alone or in combination – might affect crop harvests and food supply chains is essential to finding solutions, according to David Lobell, the Gloria and Richard Kushel Director of the Center on Food Security and the Environment. Below, Lobell discusses the connection between immigration and U.S. food security, a counter-intuitive effect of COVID-19 and more.

 

How could COVID-19 affect global food security?

I think the biggest effects will probably be related to lost incomes for many low-income people. Even if food prices don’t change, potentially hundreds of millions could be pushed into a much more precarious food situation. I’d be especially worried about remittances – the money immigrants in wealthy nations send home to developing nations – falling, since these are a surprisingly large source of stability for many poor people. Beyond the income effects, there are definitely prospects for reduced supply of foods, but I think these are secondary, especially because global stocks right now are quite large.

Another counter-intuitive effect is that the drop in gasoline demand due to social distancing may be a big driver of changes in food prices. A lot of corn demand is for use in ethanol fuel, and corn prices can affect the prices of many other crops. The price of corn has dropped by about 20 percent since February.

 

What are the biggest risks in terms of food supply?

Three things come to mind. First, for crops that require a lot of labor, there are some indications that planting and harvest activities are being affected. Even though these are usually included as essential activities, they often rely on migrant populations that can no longer cross state or national borders. California is going to be a prime case study in this.

Second, some countries, like Russia, have started to restrict food exports in an effort to calm domestic consumers worried about food shortages. Even if there is enough global supply, there is a risk that supply for importing countries could be curtailed. This was a big part of the food price spikes a decade ago. Now, we have the added potential that exports will be limited by a lack of mobility to get products to the port – for instance, there are reports from South America that towns won’t let trucks through for fear of the virus.

Third, COVID-19 could really limit the ability of governments and international groups to address other crises that emerge. Nearly every year there are at least a few surprises around the world affecting food that are usually handled before they make big news. Things like livestock diseases and crop pest outbreaks, for example. But without the ability to deploy people to assess and fix problems, there is more scope for issues to go unchecked. Right now, the biggest example of this is the desert locust outbreak in Eastern Africa.

 

What current and/or likely future weather conditions might have significant impacts on food production?

As the globe warms, we continue to see more “surprises” in most years in terms of record hot or dry growing seasons. It’s a bit too soon to say if and where those will emerge this year. Since global food stocks are high, we have some ability to cope with a shock, but if governments are already nervous it may take less to induce export bans and all of the negative effects those entail.

 

Ahead of the summer harvest, what is the prospect for controlling locust swarms in threatened countries, and how might the swarms further complicate the global food security picture?

If not for COVID-19, this would likely be the biggest development related to food this year. My understanding is that they are spreading fast in Africa and the Middle East, and while they haven’t yet had big effects in the main production regions, the next couple of months will be critical. The hope is that the winds change and drive them back toward the desert areas they came from. If not, there are at least 20 million people at risk of major food security impacts in the region.

 

Could we see locust swarms in the U.S.? What can we do to prevent them?

Locusts can occur anywhere. A few years back there was a major outbreak in Israel. They haven’t been a big issue in the U.S. because control methods are available, such as widespread spraying. But again, in a time of COVID-19, these types of responses are harder.

 

What does history teach us about the situation we are in with multiple threats to food security, and how to deal with it?

I think it comes down to a combination of investing in science-based solutions to avoid problems to begin with, and then having good social safety nets for when problems arise. At that level, it’s not really any different than dealing with infectious disease. The absence of any problems is our goal. At the same time, that absence always seems to breed complacency and neglect. Hopefully, the experiences of 2020 will help strengthen support for a society based on facts, science and compassion.

Marshall Burke and fellow researchers study productivity in smallholder farms to understand variation across the adbundant but understudied firms. They use a novel framework, satellite data, and machine learning to understand such variation, and they find that output measurement error contributes significantly to this discrepancy in productivity.

The Stanford Center at Peking University (SCPKU), the Center on Democracy, Development and the Rule of Law (CDDRL), and the APARC China Program jointly hosted a workshop on China’s Belt and Road Initiative (BRI) in early March. The workshop, held on March 2 and 3, welcomed researchers from around the world with expertise in the Initiative. Unfortunately, because of the rapidly developing health emergency related to the coronavirus, participants from not only China, but also Japan, were prevented from attending. As described by Professor Jean Oi, founding director of SCPKU and the China Program, and Professor Francis Fukuyama, director of CDDRL and the Ford Dorsey Master's in International Policy, who co-chaired the workshop, the meeting aimed to provide a global perspective on the BRI, consolidate knowledge on this opaque topic, and determine the best method and resources for future research.  

The workshop began with presentations from several of the invited guests. Dr. Atif Ansar from the University of Oxford’s Saïd Business School kicked off the first day by describing not only the tremendous opportunity that the BRI presents to developing economies, but also the serious pitfalls that often accompany colossal infrastructure projects. Pointing out the poor returns on investment of mega infrastructure projects, Ansar examined the frequest cost and schedule overruns, random disasters, and environmental degradation that outweigh the minimal benefits that they generally yield. China’s own track record from domestic infrastructure projects does little to mitigate fear of these risks, Ansar claimed. In response, he urged professional management of BRI investments, institutional reforms, and intensified deployment of technology in BRI projects. Dr. Ansar was followed by Dr. Xue Gong of the S. Rajaratnam School of International Studies, Nanyang Technological University, Singapore. Dr. Gong’s analysis centered on the extent to which China’s geopolitical motivations influenced its outward foreign direct investments (OFDI). Although her research was still in the early stages, her empirical analysis of China’s OFDI inflows into fifty BRI recipient countries from 2007-2018 nevertheless revealed that geopolitical factors often outweigh economic factors when it comes to China’s OFDI destinations.

Amit Bhandari of Gateway House: Indian Council on Global Relations presents his research at the Belt and Road Workshop.
Participants then heard presentations from Amit Bhandari of Gateway House: Indian Council on Global Relations and Professor Cheng-Chwee Kuik of the National University of Malaysia. Mr. Bhandari’s talk focused on Chinese investments in India’s six neighboring countries, which tend to center more on energy rather than connectivity projects. He first found that the investments are generally not economical for the host countries because they come with high costs and high interest rates. Secondly, he argued that these projects often lacked a clear economic rationale, appearing instead to embed a geopolitical logic not always friendly to India. Professor Kuik, by contrast, provided a counterexample in his analysis of BRI projects in Southeast Asia. He described how, in Southeast Asia, host countries’ reception of the BRI has varied substantially; and how various stakeholders, including states, sub-states and other entities, have used their leverage to shape outcomes more or less favorable to themselves. Kuik’s analysis injected complexity into the often black-and-white characterizations of the BRI. He highlighted the multidimensional dynamics that play out among local and state-level players in pursuit of their goals, and in the process of BRI implementation.

Professor Curtis J. Milhaupt and Scholar-in-Residence Jeffrey Ball, both at Stanford Law School, followed with individual presentations on the role of State-Owned Enterprises (SOEs) in the BRI and the emissions impact of the BRI on climate change, respectively. Professor Milhaupt  characterized Chinese SOEs as both geopolitical and commercial actors, simultaneously charged with implementing Party policies and attaining corporate profits. Chinese SOEs are major undertakers of significant overseas BRI projects, acting not only as builders but also as investors, partners, and operators. This situation, Milhaupt asserted, carries significant risks for SOEs because these megaprojects often provide dismal returns, have high default rates, and can trigger political backlash in their localities. Milhaupt highlighted the importance of gathering firm-level data on businesses actually engaged in BRI projects to better infer geostrategic, financial, or other motivations. Jeffrey Ball turned the discussion to carbon emissions from BRI projects and presented preliminary findings from his four-country case studies. He concluded that, on aggregate, the emissions impact of the BRI is still “more brown than green.” Twenty-eight percent of global carbon emissions may be accounted for by BRI projects, Ball asserted, underscoring the importance of the BRI to the future of global climate change.

The day concluded with presentations by  Michael Bennon, Managing Director at the Stanford Global Projects Center, and Professor David M. Lampton, Oksenberg-Rohlen Fellow at the Freeman Spogli Institute for International Studies. Bennon first presented findings from two empirical case studies of BRI projects and then went on to describe how the BRI is now practically the “only game in town” for infrastructure funding for developing countries. Lengthy environmental review processes at Western multilateral banks have turned the World Bank, for example, from a lending bank into a “knowledge bank,” he argued. He also highlighted that, in general, economic returns on BRI projects for China are very poor, even though recipient countries may accrue macroeconomic benefits from these projects. Finally, Professor Lampton turned the discussion back to Southeast Asia, where China is currently undertaking massive cross-border high-speed rail projects through eight ASEAN countries. He described how each host country had varying capacity to negotiate against its giant neighbor, and how the sequential implementation of these cross-border rail projects also had varying impacts on the negotiating positions of these host countries. BRI played out differently in each country, in other words, eliciting different reactions, push-backs and negotiated terms.

The second day of the workshop was dedicated to working toward a collaborative approach to future BRI research. The group discussed the key gaps in the existing research, including how to know what China’s true intentions are, how to measure those intentions, who the main players and their interests in both China and the host countries are, and even what the BRI is, exactly. Some cautioned that high-profile projects may not be representative of the whole. Participants brainstormed about existing and future sources of data, and stressed the importance of diversifying studies and seeking empirical evidence.

The past four decades have witnessed unprecedented economic growth and rapidly rising food demand in China. This paper provides an introduction to readers with useful information summarising the development of China’s agricultural sector and the transformation of its rural economy over the 40 years of economic reform. It is, however, impossible to cover all aspects of this recent and rich history in a single journal special issue. Nevertheless, we are of the view that these papers address the most fundamentally important and insightful topics including: land reform and rural development; technology progress and productivity growth; changing food consumption patterns; rural education and human capital accumulation; and poverty alleviation.

Wheat is the most important Ethiopian crop, and rust one of its greatest antagonists. There is a need for cheap and scalable rust monitoring in the developing world, but existing methods employ costly data collection techniques. We introduce a scalable, accurate, and inexpensive method for tracking outbreaks with publicly available remote sensing data. Our approach improves existing techniques in two ways. First, we forgo the spectral features employed by the remote sensing community in favor of automatically learned features generated by Convolutional and Long Short-Term Memory Networks. Second, we aggregate data into larger geospatial regions. We evaluate our approach on nine years of agricultural outcomes, show that it outperforms competing techniques, and demonstrate its predictive foresight. This is a promising new direction in crop disease monitoring, one that has the potential to grow more powerful with time.

Eradicating hunger and malnutrition is a key development goal of the twenty first century. This paper addresses the problem of optimally identifying seed varieties to reliably increase crop yield within a risk-sensitive decision making framework. Specifically, a novel hierarchical machine learning mechanism for predicting crop yield (the yield of different seed varieties of the same crop) is introduced. This prediction mechanism is then integrated with a weather forecasting model and three different approaches for decision making under uncertainty to select seed varieties for planting so as to balance yield maximization and risk. The model was applied to the problem of soybean variety selection given in the 2016 Syngenta Crop Challenge. The prediction model achieved a median absolute error of 235 kg/ha and thus provides good estimates for input into the decision models. The decision models identified the selection of soybean varieties that appropriately balance yield and risk as a function of the farmer’s risk aversion level. More generally, the models can support farmers in decision making about which seed varieties to plant.
