The lost decades for China in the 1950s, 1960s and 1970s look remarkably like the lost decades of Africa in the 1980s and 1990s. Poor land rights, weak incentives, incomplete markets and inappropriate investment portfolios. However, China burst out of its stagnation in the 1980s and has enjoyed three decades of remarkable growth. In this paper we examine the record of the development of China’s food economy and identify the policies that helped generate the growth and transformation of agriculture. Incentives, markets and strategic investments by the state were key. Equally important, however, is what the state did not do. Policies that worked and those that failed (or those that were ignored) are addressed. Most importantly, we try to take an objective, nuanced look at the lessons that might be learned and those that are not relevant for Africa. Many parts of Africa have experienced positive growth during the past decade. We examine if there are any lessons that might be helpful in turning ten positive years into several more decades of transformation.

FSE associate director David Lobell delivers a lecture on "Understanding the limits of crops (and models) under extreme heat" as part of UC Davis' Climate-Smart Agriculture conference. Special Session - #7. Lobell's talk begins at 51:00.
About the topic: The Office of the UN High Commissioner for Refugees approached CISAC last year to collaborate on a project to improve conditions among global refugee communities. This has led to a multidisciplinary partnership involving CISAC, students from across the Stanford campus and at the Hasso Plattner Institute of Design. Professors, NGOs, physicians, architects and other professionals have all volunteered time and expertise. The project led to a Law School class, "Rethinking Refugee Communities," co-taught by CISAC's Tino Cuéllar and IDEO's Leslie Witt. Four students representing teams from the class recently traveled to refugee camps in western Ethiopia on the border with Sudan. They conducted field research for their projects focused on camp communications; early camp setup and registration; food security and economic sustainability; and host community relations.
Speakers include:
Parth Bhakta, Co-term senior and first-year graduate student, Computer Science
Beth Duff-Brown,Communications and Editorial Manager, CISAC
Jessica Miranda Garcia, Second-year graduate student, International Policy Studies
Benjamin Rudolph, Senior, Computer Science
Devorah West, Second-year graduate student, International Policy Studies
This project will focus on the potential role of fertilizer in the intensification of maize production amongst Zambian smallholders. Data to be analyzed during this research includes household survey data and linked soil analysis data.
Households depend upon food prices, incomes, and disease burdens that impact the ability to use consumed food. Climate change and extreme temperatures impact all of these factors. In this talk, David Lobell focuses on the impact of heat in growing regions that are important for food prices. He reviews recent research on heat impacts and discusses whether crop yields are becoming more or less sensitive to heat.
According to a new study by FSE's David Lobell, satellite data can play a critical role in understanding yield gaps and meeting future crop demand. Lobell's review appeared in a special issue in Field Crops Research dedicated to crop yield gap analysis.
To date, satellite data have played a relatively small role in understanding the magnitude and causes of yield gaps in most regions. However, the few examples that exist indicate that remote sensing can help to overcome some of the inherent spatial and temporal scaling issues associated with field-based approaches.
"Yield gap profiles, based on multiple years of satellite data, provide a useful measure of how persistent yield-controlling factors are through time," writes Lobell in his review. "Although the cost or availability of satellite data with sufficient spatial resolution to discriminate agricultural fields was an obstacle in the past, this barrier is rapidly diminishing."
Improved algorithms to pre-process remote sensing data and estimate yields, and the increased availability of new, large geospatial datasets on soils, management, and weather should also benefit future efforts in this area.
"Improved knowledge of yield gaps will play a critical role in meeting future crop demands at affordable prices and with minimal environmental impacts," concludes Lobell. "The use of satellite data can accelerate the pace of discovery, and as such it represents an important area for future work."
All papers in this special issue can be accessed free of charge.
Stanford experts from a range of disciplines will discuss the interconnections and interactions among humanity’s need for and use of energy, food, water, and environmental resources. Drawing on their own research, each speaker will illustrate and evaluate some of the ways in which decisions in one resource area can lead to trade-offs or co-benefits in other areas. Stanford students and faculty will lead interactive breakout sessions to explore a range of challenges associated with energy transitioning to a sustainable system.

Several aid groups have proposed strategies for allocating ready-touse (therapeutic and supplementary) foods to children in developing countries. Analysis is needed to investigate whether there are better alternatives. We use a longitudinal dataset of 5,657 children from Bwamanda to construct a bivariate time-series model that tracks each child’s height-for-age z score (HAZ) and weight-forheight z score (WHZ) throughout the first 5 y of life. Our optimization model chooses which individual children should receive readyto-use therapeutic or supplementary food based on a child’s sex, age, HAZ, and WHZ, to minimize the mean number of disabilityadjusted life years (DALYs) per child during 6–60 mo of age [which includes childhood mortality calculated from a logistic regression and the lifelong effects of stunting (i.e., low HAZ)] subject to a budget constraint. Compared with the strategies proposed by the aid groups, which do not use HAZ information, the simple strategy arising from our analysis [which prioritizes children according to low values of a linear combination of HAZ, WHZ, and age and allocates the entire budget to therapeutic (i.e., 500 kcal/d) food for the prioritized children] reduces the number of DALYs by 9% (for the same budget) or alternatively incurs the same number of DALYs with a 61% reduction in cost. Whereas our qualitative conclusions appear to be robust, the quantitative results derived from our analysis should be treated with caution because of the lack of reliable data on the impact of supplementary food on HAZ and WHZ, the application of our model to a single cohort of children and the inclusion and exclusion errors related to imperfect food targeting.
Many Stanford computer science majors hope to land coveted jobs in Silicon Valley upon graduation. Parth Bhakta or Ben Rudolph aren't so sure. They first want to take their skills far afield of the storied technology hub.
Bhakta and Rudolph joined two other Stanford students earlier this month to travel to Ethiopia, making their way to remote refugee camps along the Sudanese border. They are researching ways in which technology and design innovation can help improve conditions for refugees and their surrounding communities.
“As a computer science student, I feel that a lot of Silicon Valley is focused on solving trivial problems,” said Bhakta, a senior from Palm Desert, Calif., who graduates this year with an undergraduate degree in symbolic systems and a master’s in computer science. “I hope to apply my skills toward something that has a meaningful impact. I want this experience to help me better understand how to tackle big, tangible problems.”
The students worked with the UNHCR and International Rescue Committee in the Bambasi and Sherkole refugee camps in western Ethiopia to test out ideas they’ve been working on with the goal of improving camp communications; food security and economic self-sufficiency; host community relations; and the often difficult process of setting up camps to house arriving refugees.
The idea for the trip emerged from a dialogue and collaboration between Stanford’s Center for International Security and Cooperation (CISAC) and the United Nations High Commissioner for Refugees (UNHCR). An official from the UN agency approached CISAC Co-Director Tino Cuéllar last spring, and encouraged CISAC to explore ideas to better protect and support the care of more than 42 million refugees, internally displaced and stateless people worldwide.
These early discussions led to a multidisciplinary partnership involving CISAC, students from across the Stanford campus and at the Hassno-Platner Institute of Design – better known as the d.school – as well as professors, NGOs, physicians, officials with experience in humanitarian settings, architects and other professionals eager to volunteer their time and expertise.
Among those professionals is Jeffrey Geisinger, an architect with Ennead Architects in New York. The firm, which designed the new Stanford Law School wing and the recently inaugurated Bing Concert Hall, is doing pro bono work on the project through its advocacy lab.
Geisinger hopes to start designing modules that might be used in shared spaces. To do this, he said, he must see what construction materials are available, what deficiencies typically exist out in the field and which social networks and local skills might be tapped to help the UN build more innovative structures shared by both communities.
“From an architect’s perspective, we’re interested in some kind of design solution,” said Geisinger. “But before we can even begin to put pencil to paper, it’s important to really define the problem.”
For CISAC, the project represents a further effort to bridge the gap between scholarship and practice.
“This is an extraordinary manifestation of CISAC’s mission to help shape public policy,” said Liz Gardner, CISAC’s associate director for programs. “This project marries up scholarship, teaching and close interaction with policymakers – with the ultimate goal of improving the lives of refugees.”
The project also led to dozens of students from a variety of majors to enroll in the Law School class, “Rethinking Refugee Communities,” co-taught by Cuéllar and Leslie Witt of the global design consultancy, IDEO. The students have been brainstorming and investigating, then hammering out concepts and prototypes they hope might one day be implemented by the United Nations.
Now, they want to put those ideas to the test.
Rudolph, a senior from Chicago, is working with his team to build a software platform that would enable early camp registration and provide two-way communication between the UNHCR and refugees, using mobile technology. RescueSMS is software designed to better profile each refugee and alert them to upcoming events or emergencies in the camp, as well as give them a voice to express concerns or ask questions of the UN.
“I’m excited about applying my computer science knowledge to humanitarian efforts, where I think software is underused,” said Rudolph, who has had a string of internships at Silicon Valley startups. “I wanted a change of pace from the corporate world; I was tired of working for traditional software startup companies.”
So he’s taking an untraditional route. Rudolph’s interest in the project has led to an internship with the UNHCR’s innovation lab in Geneva after he graduates this summer.
One of Cuéllar’s goals is to build long-term relationships with organizations such as the UNHCR so that the work by Stanford students becomes embedded in the innovation process of public organizations.
Devorah West’s team is looking at infrastructure in the space that is shared by refugees and the indigenous people from the surrounding community. When thousands of refugees stream into border communities in neighboring countries, resources become scarce and tensions run high. West is representing the team looking at ways to build schools, medical facilities and marketplaces that could be shared by both communities.
“My team will use this trip to get a better understanding of realities on the ground,” said West, a second-year master’s student in international policy studies from Santa Fe, N.M., who graduates this summer. “We hope to find ways to defuse tensions over scarce resources and allow both communities to satisfy social and physical needs.”
West said she was drawn to the project by the interdisciplinary nature of the teams.
“Having worked in the policy world, I was really interested in using design thinking to fuse together academic research and policy development in order to have a concrete impact on refugee communities,” she said.
Jessica Miranda is representing the team focused on food security and economic self-sufficiency. They are working on understanding how to encourage small-scale mobile farming. During her visits to the camps, she will investigate the challenges that affect small-scale gardening and learn more about the terrain, the nutritional status of vulnerable households and what the cultural views are on agriculture.
“I know how it feels to leave your country behind,” said Miranda, a second-year master’s student in international policy studies from Toluca, Mexico. “And I want to help. But it’s difficult to think about refugee camps from the comfort of my couch. It’s time to go and see how these ideas might work on the ground."
Beth Duff-Brown, CISAC’s communications manager, traveled with the students and will be reporting from the field.
