Environment

FSI scholars approach their research on the environment from regulatory, economic and societal angles. The Center on Food Security and the Environment weighs the connection between climate change and agriculture; the impact of biofuel expansion on land and food supply; how to increase crop yields without expanding agricultural lands; and the trends in aquaculture. FSE’s research spans the globe – from the potential of smallholder irrigation to reduce hunger and improve development in sub-Saharan Africa to the devastation of drought on Iowa farms. David Lobell, a senior fellow at FSI and a recipient of a MacArthur “genius” grant, has looked at the impacts of increasing wheat and corn crops in Africa, South Asia, Mexico and the United States; and has studied the effects of extreme heat on the world’s staple crops.

The Freeman Spogli Institute for International Studies (FSI) at Stanford University is pleased to announce that former U.S. Ambassador and World Food Programme (WFP) Executive Director Ertharin Cousin will return for a second year at Stanford. Cousin will serve as the Frank E. and Arthur W. Payne Distinguished Lecturer at FSI and Distinguished Fellow at the Center on Food Security and the Environment and the Center on Democracy, Development and the Rule of Law.

Cousin brings over 30 years of experience addressing hunger and food security strategies on both a national and international scale. As U.S. Ambassador to the United Nations Agencies for Food and Agriculture, she focused on advocating for longer-term solutions to food insecurity and hunger, and at WFP she addressed the challenges of food insecurity in conflict situations.

We caught up with Cousin to ask about her plans for this upcoming school year.

If you had to pick out one thing that most concerns you in the realm of food security, what would it be?

Water access, particularly in terms of smallholder farmer centered irrigation and water management. The development community spent much of the past 10 years working to improve farmers’ access to the right seeds and tools – recognizing the need to increase the quality and quantity of their yields. A significant amount of work has also been performed related to improving private sector investment and to the development of markets including access for smallholder farmers.

Today there are approximately 500 million smallholder farmers in the world. The most vulnerable live and work in places where climate change creates ever more erratic rainy seasons. Particularly, in sub-Saharan Africa where 97 percent of all agriculture remains rain-fed. Too often the short rains don’t come, and the long rains produce insufficient precipitation. Inadequate policy management of diminishing water resources represents a significant problem which we must overcome to make agriculture productive and sustainable for the most vulnerable.

And what work have you been doing to address this issue?

I am working on a number of policy research and development projects. For example, I am co-chairing the Chicago Council on Global Affairs (CCGA) 2019 Global Food Security Symposium’s report exploring the linkages between water management and food security particularly as it relates to nutrition security. The report release will occur March 21, 2019 at the CCGA Food Security Symposium.

Over the past year, you also have been working on a project to encourage the private sector to create sustainable food systems. How is that going?

My work identifying and addressing policy-related challenges impacting private sector partnership and investment in global food system solutions continues. Globally, there is growing recognition that we cannot fix the broken global food system if we do not work to create collaborative efforts between public and private sector, academia, government, non-profits and larger society.

Governments, particularly those in developing countries, often lack both the financial resources and technical capacity required to perform the work and the investment necessary to fix our global food system. Governments and civil society must include private sector as an equal and desired partner. Government policies at the global, state and local level should support and encourage private sector participation.

Using my role here at Stanford as a platform to broker research and information both to private sector as well as to government, has proven quite successful over the past year. In very simple terms, helping global governments understand generating profit does not make the private sector a bad partner.

What successes have you had so far?

I was just in Amsterdam to meet with Royal DSM, a nutrition products manufacturer, with whom I developed a relationship during my tenure at the World Food Programme. In Kigali in Rwanda, DSM and several other partners - including the national government - have developed and are now operating the Africa Improved Foods company, the first European-type baby food manufacturing facility. European-type baby food differs from American products in terms of their lack of sweeteners and conservative use of food preservatives, lack of detectable pesticides (due to farming practices), and their stage-approach: they produce different products for the various stages of baby growth (from birth to 4 years) that cater to the specific nutritional needs of the child. Several farming cooperatives, representing approximately 10,000 Rwandan small farmers, form the sole supply chain for this baby food factory.

WFP serves as a catalyst market for the plant, purchasing the supplemental nutrition product distributed through the region’s targeted nutrition improvement program. The sustainability of the factory is directly related to the partners ability to grow (in addition to WFP) an institutional and a commercial consumer market for this easy-access, nutrient-rich food that is specifically made for children. I am assisting DSM and the government of Rwanda by helping to identify the policy changes required to ensure the sustainability of this public-private partnership. As a proof-of-concept, the success of AIF, will result in new public-private development opportunities. This initiative offers a case study demonstrating how collaboration between the private sector and government actually provides positive benefits for both farmers and nutritious food for consumers.

Why Stanford? How has being here helped your work?

Serving here at Stanford represents my first opportunity to work in academia on a full-time basis. I am a lawyer with over 30 years of experience of working on complicated domestic and global humanitarian and development issues; particularly, hunger related issues. I believe my experience adds value to any academic community. But in many institutions, the value of experience is not readily embraced, particularly because I don't have a PhD and haven’t spent 20 years in a classroom. At Stanford, I discovered collegial faculty, brilliant students and a recognition as well as a respect for my experience-based knowledge. I have received a welcoming response across the campus, collaborating with the law school, colleagues in the medical school, earth system sciences and the business school. The only limit to my participation and partnership with the amazing academic leaders here at Stanford has been time. I am quite looking forward to the opportunities for engagement provided by my additional time on campus.

By comparing historical temperature and suicide data, researchers found a strong correlation between warm weather and increased suicides. They estimate climate change could lead to suicide rate increases across the U.S. and Mexico.

Suicide rates are likely to rise as the earth warms, according to new research published July 23 in Nature Climate Change. The study, led by Stanford economist Marshall Burke, finds that projected temperature increases through 2050 could lead to an additional 21,000 suicides in the United States and Mexico.

“When talking about climate change, it’s often easy to think in abstractions. But the thousands of additional suicides that are likely to occur as a result of unmitigated climate change are not just a number, they represent tragic losses for families across the country,” said Burke, assistant professor of Earth system science in the School of Earth, Energy & Environmental Sciences at Stanford.

Researchers have recognized for centuries that suicides tend to peak during warmer months. But, many factors beyond temperature also vary seasonally – such as unemployment rates or the amount of daylight – and up to this point it has been difficult to disentangle the role of temperature from other risk factors.

“Suicide is one of the leading causes of death globally, and suicide rates in the U.S. have risen dramatically over the last 15 years. So better understanding the causes of suicide is a public health priority,” Burke said.

Heat and suicide

To tease out the role of temperature from other factors, the researchers compared historical temperature and suicide data across thousands of U.S. counties and Mexican municipalities over several decades. The team also analyzed the language in over half a billion Twitter updates or tweets to further determine whether hotter temperatures affect mental well-being. They analyzed, for example, whether tweets contain language such as “lonely,” “trapped” or “suicidal” more often during hot spells.

The researchers found strong evidence that hotter weather increases both suicide rates and the use of depressive language on social media.

“Surprisingly, these effects differ very little based on how rich populations are or if they are used to warm weather,” Burke said.

For example, the effects in Texas are some of the highest in the country. Suicide rates have not declined over recent decades, even with the introduction and wide adaptation of air conditioning. If anything, the researchers say, the effect has grown stronger over time.

Effect of climate change

To understand how future climate change might affect suicide rates, the team used projections from global climate models. They calculate that temperature increases by 2050 could increase suicide rates by 1.4 percent in the U.S. and 2.3 percent in Mexico. These effects are roughly as large in size as the influence of economic recessions (which increase the rate) or suicide prevention programs and gun restriction laws (which decrease the rate).

“We’ve been studying the effects of warming on conflict and violence for years, finding that people fight more when it’s hot. Now we see that in addition to hurting others, some individuals hurt themselves. It appears that heat profoundly affects the human mind and how we decide to inflict harm,” said Solomon Hsiang, study co-author and associate professor at the University of California, Berkeley.

The authors stress that rising temperature and climate change should not be viewed as direct motivations for suicide. Instead, they point out that temperature and climate may increase the risk of suicide by affecting the likelihood that an individual situation leads to an attempt at self-harm.

“Hotter temperatures are clearly not the only, nor the most important, risk factor for suicide,” Burke emphasized. “But our findings suggest that warming can have a surprisingly large impact on suicide risk, and this matters for both our understanding of mental health as well as for what we should expect as temperatures continue to warm.”

Marshall Burke is also a fellow at the Center on Food Security and the Environment, Stanford Woods Institute for the Environment, Freeman Spogli Institute for International Studies, and Stanford Institute for Economic Policy Research. Solomon Hsiang is also a faculty research fellow at the National Bureau of Economic Research. Other Stanford co-authors include Sanjay Basu, assistant professor of medicine, and Sam Heft-Neal, research scholar at the Stanford Center on Food Security and the Environment. Additional co-authors are from Pontificia Universidad Católica de Chile, Vancouver School of Economics, and the University of California, Berkeley. The research was partially supported by the Stanford Woods Institute for the Environment.

The rising level of carbon dioxide in the atmosphere means that crops are becoming less nutritious, and that change could lead to higher rates of malnutrition that predispose people to various diseases.

That conclusion comes from an analysis published Tuesday in the journal PLOS Medicine, which also examined how the risk could be alleviated. In the end, cutting emissions, and not public health initiatives, may be the best response, according to the paper's authors.

Research has already shown that crops like wheat and rice produce lower levels of essential nutrients when exposed to higher levels of carbon dioxide, thanks to experiments that artificially increased CO2 concentrations in agricultural fields. While plants grew bigger, they also had lower concentrations of minerals like iron and zinc.

Poor air quality is thought to be an important mortality risk factor globally1,2,3, but there is little direct evidence from the developing world on how mortality risk varies with changing exposure to ambient particulate matter. Current global estimates apply exposure–response relationships that have been derived mostly from wealthy, mid-latitude countries to spatial population data4, and these estimates remain unvalidated across large portions of the globe. Here we combine household survey-based information on the location and timing of nearly 1 million births across sub-Saharan Africa with satellite-based estimates5 of exposure to ambient respirable particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5) to estimate the impact of air quality on mortality rates among infants in Africa. We find that a 10 μg m−3 increase in PM2.5 concentration is associated with a 9% (95% confidence interval, 4–14%) rise in infant mortality across the dataset. This effect has not declined over the last 15 years and does not diminish with higher levels of household wealth. Our estimates suggest that PM2.5 concentrations above minimum exposure levels were responsible for 22% (95% confidence interval, 9–35%) of infant deaths in our 30 study countries and led to 449,000 (95% confidence interval, 194,000–709,000) additional deaths of infants in 2015, an estimate that is more than three times higher than existing estimates that attribute death of infants to poor air quality for these countries2,6. Upward revision of disease-burden estimates in the studied countries in Africa alone would result in a doubling of current estimates of global deaths of infants that are associated with air pollution, and modest reductions in African PM2.5 exposures are predicted to have health benefits to infants that are larger than most known health interventions.

Paul N. Edwards of CISAC has been appointed as a lead author for the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). The IPCC is the scientific organization supporting the United Nations Framework Convention on Climate Change (UNFCCC).  Organized by the United Nations and the World Meteorological Organization, the IPCC’s reports provide the scientific underpinnings for the international climate negotiations that led to the 1997 Kyoto Protocol and the 2015 Paris Agreement on climate change.

The IPCC reviews the state of the science of climate change every 5-7 years. Its Sixth Assessment Report—to which Edwards will contribute--will be completed in 2021. Edwards will serve as lead author for four years to develop, review, and complete the assessment.

Through his appointment, Edwards becomes the first social scientist to serve as a lead author in Working Group 1, which assesses the physical science of climate change. The other two working groups deal with impacts, adaptation, and vulnerability (Working Group 2) and mitigation of climate change (Working Group 3).  Edwards will travel to Guangzhou, China, next week for the first meeting of lead author—a trip for which he has purchased carbon offsets.

 

Paul N. Edwards is William J. Perry Fellow in International Security and Senior Research Scholar at CISAC, as well as Professor of Information and History at the University of Michigan. At Stanford, his teaching includes courses in the Ford Dorsey Program in International Policy Studies and the Program in Science, Technology & Society. His research focuses on the history, politics, and culture of knowledge and information infrastructures. He focuses especially on environmental security, including climate change, Anthropocene risks, and nuclear winter.

Edwards’s book A Vast Machine: Computer Models, Climate Data, and the Politics of Global Warming (MIT Press, 2010), a history of the meteorological information infrastructure, received the Computer Museum History Prize from the Society for the History of Technology, the Louis J. Battan Award from the American Meteorological Society, and other prizes. The Economist magazine named A Vast Machine a Book of the Year in 2010. Edwards’s book The Closed World: Computers and the Politics of Discourse in Cold War America (MIT Press, 1996) — a study of the mutual shaping of computers, military strategy, and the cognitive sciences from 1945-1990 — won honorable mention for the Rachel Carson Prize of the Society for Social Studies of Science. Edwards is also co-editor of Changing the Atmosphere: Expert Knowledge and Environmental Governance (MIT Press, 2001) and Changing Life: Genomes, Ecologies, Bodies, Commodities (University of Minnesota Press, 1997), as well as numerous articles.

Paragraphs

International climate change agreements typically specify global warming thresholds as policy targets, but the relative economic benefits of achieving these temperature targets remain poorly understood. Uncertainties include the spatial pattern of temperature change, how global and regional economic output will respond to these changes in temperature, and the willingness of societies to trade present for future consumption. Here we combine historical evidence with national-level climate and socioeconomic projections to quantify the economic damages associated with the United Nations (UN) targets of 1.5 °C and 2 °C global warming, and those associated with current UN national-level mitigation commitments (which together approach 3 °C warming). We find that by the end of this century, there is a more than 75% chance that limiting warming to 1.5 °C would reduce economic damages relative to 2 °C, and a more than 60% chance that the accumulated global benefits will exceed US$20 trillion under a 3% discount rate (2010 US dollars). We also estimate that 71% of countries—representing 90% of the global population—have a more than 75% chance of experiencing reduced economic damages at 1.5 °C, with poorer countries benefiting most. Our results could understate the benefits of limiting warming to 1.5 °C if unprecedented extreme outcomes, such as large-scale sea level rise, occur for warming of 2 °C but not for warming of 1.5 °C. Inclusion of other unquantified sources of uncertainty, such as uncertainty in secular growth rates beyond that contained in existing socioeconomic scenarios, could also result in less precise impact estimates. We find considerably greater reductions in global economic output beyond 2 °C. Relative to a world that did not warm beyond 2000–2010 levels, we project 15%–25% reductions in per capita output by 2100 for the 2.5–3 °C of global warming implied by current national commitments, and reductions of more than 30% for 4 °C warming. Our results therefore suggest that achieving the 1.5 °C target is likely to reduce aggregate damages and lessen global inequality, and that failing to meet the 2 °C target is likely to increase economic damages substantially.

This report was produced for the Abe Fellows Global Forum 2017 symposiums on climate change, held in partnership with Stanford University's Walter H. Shorenstein Asia Pacific Research Center (Abe Global | Stanford, October 20, 2017) and the Asia Society Texas Center (Abe Global | Houston, October 18, 2017), respectively. 

Energy-intensive production has been both a leading contributor to climate change as well as one of the keys to modern economic growth over the last several centuries. In the post-WWII era, the “economic miracles” of Asian growth—starting with Japan, and followed by South Korea, Taiwan, China, and now increasingly India—have lifted hundreds of millions of people out of poverty. At the same time, these “economic miracles” have created huge pollution problems which have adversely affected the health of millions of people while speeding up the effects of climate change.

Some early developers from this group—including Japan—have made efforts to clean up their air and water, created more energy efficient economies, lowered their carbon footprints and contributed to initiatives to slow global warming. The Fukushima nuclear power plant disaster forced Japan to take even more aggressive action to reduce energy consumption and lessen its impact on the global environment. In contrast, the United States, as a sizeable nation-state both in its geographic area and economy, is one of the world’s largest polluters and recently made recent headlines when it withdrew from the Paris Agreement negotiated at the 2015 United Nations Climate Change Conference (COP21).

Putting into place effective measures to curtail climate change while creating sustainable societies requires international cooperation. The series of extreme weather events in the US in 2017 are only some the most recent disasters to remind us of climate change’s threat to our economy, our society, and our individual daily lives.
