Policies that promote biofuels in major agricultural economies raise important questions for food prices and food security at local to global scales. Global biofuel output rose from 38 billion liters to 131 billion liters between 2005 and 2015, boosting the demand for annual- and perennial-crop feedstocks such as maize, sugar, soy, rapeseed, and palm oil. Although ethanol volume was three times that of biodiesel in 2015, the share of biodiesel in total biofuel output rose from 10% to almost 25% over the course of the decade (EIA, n.d.; REN21, 2016). Biodiesel production increased 700% between 2005 and 2015 and is expected to rise by another 35% by 2025 (OECD/FAO, 2014). In this paper, we examine the linkages between biodiesel, oil crop, and energy markets, and ask: What are the food security implications of biodiesel policies in major agricultural economies? How do governments adjust biodiesel policies in response to international commodity prices, trade opportunities, and their changing economic and environmental priorities?

The rise in global biodiesel production: Implications for food security
Food security experts identify government support, policy implementation, private sector engagement and investment in smallholder farmers as keys to Africa’s agricultural future.
Food security experts from the Alliance for a Green Revolution in Africa (AGRA) gathered to discuss transforming food production in Africa at Stanford on Nov. 29. The symposium, hosted by the Center on Food Security and the Environment (FSE) examined the challenges, strategies, and possible solutions for catalyzing and sustaining an inclusive agriculture transformation in Africa.
Moderator Ertharin Cousin, FSE visiting fellow and previous World Food Programme director with more than 25 years of experience on hunger, food, and resilience strategies, launched the panel by outlining Africa’s plight. “Today some 100 million of the farmers across Sub-Saharan Africa farm less than 2 hectares of land. Some 80 percent of those living in rural areas are poor. More than 30 percent of the rural population is chronically hungry and 35 percent of the under-five-year-olds are stunted. By 2050, the bulk of the world's population growth will take place on the continent. In fact, some project that 1.3 billion will be added to the continent, and Nigeria’s [population] will grow larger than the size of the United States between now and 2050,” Cousin said
.
While Africa continues to experience the highest occurrence of food insecurity worldwide, the continent also contains over 60 percent of the worlds uncultivated but fertile land. AGRA formed in 2006 to fulfill the vision that Africa can feed itself and the world. Panelists included Agnes Kalibata, AGRA President and former Minister of Agriculture and Animal Resources of Rwanda; Kanayo F. Nwanze, AGRA board member and immediate past president of the International Fund for Agricultural Development; Usha Barwale Zehr, AGRA board member and Director and Chief Technology Officer of Maharashtra Hybrid Seeds Company Private Limited; and Rajiv Shah, AGRA board member, Rockefeller Foundation President and former Administer of USAID.
Kanayo F. Nwanze stressed the importance of agricultural transformation for Africa’s future. “No country in the world ever transformed itself without going through an agrarian change. No country. Europe, 17th; Japan, 18th century; 19th century was the US, your country; China, 20th century. Why should they be different from Africa? So, first and foremost, we have to have total agricultural transformation,” Nwanze said.
AGRA president, Agnes Kalibata, also spoke to the need for policy implementation and government support in helping drive change. “AGRA as an institution can only do so much. But these governments have the potential and the capacity to reach every corner of their countries. The problem is they are challenged by capacity to do that, by capacity to design proper programs, and by capacity to implement these programs,” Kalibata said.
Expanding on governments' ability to impact and drive change, Usha Barwale Zehr highlighted Asia’s success, specifically with strategic partnerships. “…we've done a lot of talking about public/private partnership. Not so much on the ground on implementing it in a manner, which happened in Asia, for instance, where there was policy, and, most importantly, government will. The government was willing to do whatever it took to make sure that agriculture was transformed at the end of it,” Zehr said.
Beyond government and policy support the panelists also addressed the need for innovation and access to seed technologies. “Why is it that the African farmer and the Indian farmer should not have access to what the American farmer has access to today and reaps benefit from it? …So it's the hybrids, the varieties, the GM technology. Tomorrow it'll be the gene-edited products. And after that we will talk about the satellite-based imaging data that we will use for developing drought-tolerant crops for that very, very small micro environment that existed in the one district in Nigeria,” Zehr said.
"By 2050, who is going to feed Africa? … It's the youth of today. But they're not going to be using the same technologies that exist today. Just think of what IT can do, aggregation, organization of farmer's groups. So, the elements are there. I see the agriculture of tomorrow meeting the challenge – for Africa meeting that challenge is Africa being at the forefront of feeding the world. Africa has to be able to feed itself first. And we have all the opportunities there,” Nwanze said.

Abstract: Clean energy provides a number of benefits at scales from household to village to city and region. An unrealized and under-appreciated opportunity is to transition conflict regions from external fuel supply chains to local, clean and unpolluting energy. The benefits of this transition include local energy security to shared benefits from sustaining local generation capacity, which we term 'peace through grids'.

Stanford’s Center on Food Security and the Environment launches new symposium series focused on global food security with panel exploring Africa’s agricultural potential.
Organized by the Center on Food Security and the Environment (FSE), the Nov. 29 symposium is the first in the center’s new Global Food Security Symposium series. Panel members include visiting AGRA board members, who will examine the challenges, strategies, and possible solutions for catalyzing and sustaining an inclusive agriculture transformation in Africa. This symposium marks the third series established by FSE convening thought leaders addressing global food security issues.
Afflicted by conflict, political upheaval, and extreme weather patterns Africa continues to experience the highest occurrence of food insecurity. However, with over 60 percent of the worlds uncultivated but fertile land, there is significant room for improvement. AGRA formed in 2006 to fulfill the vision that Africa can feed itself and the world. As an alliance led by Africans with roots in farming communities across the continent, they work to understand the unique needs of farmers and offer sustainable solutions designed to boost production.
In a region with 27.4 percent of the population currently experiencing food insecurity, creating a sustainable agricultural revolution remains a key solution to improving food security across the area. Moderated by Ertharin Cousin, previous World Food Programme director, with 25 years of experience on hunger, food, and resilience strategies, the panel will explore how an agricultural transformation in Africa can sustain a growing population, relieve hunger, generate jobs, improve social cohesion, and create global exports.
Panel members include: Ertharin Cousin (moderator), Payne Distinguished Lecturer at the Freeman Spogli Institute for International Studies and Visiting Fellow at the Center on Food Security and the Environment, former US Ambassador to the UN Agencies for Food and Agriculture in Rome.

Elevated atmospheric CO2 concentrations ([CO2]) are expected to increase C3 crop yield through the CO2 fertilization effect (CFE) by stimulating photosynthesis and by reducing stomatal conductance and transpiration. The latter effect is widely believed to lead to greater benefits in dry rather than wet conditions, although some recent experimental evidence challenges this view. Here we used a process-based crop model, the Agricultural Production Systems sIMulator (APSIM), to quantify the contemporary and future CFE on soybean in one of its primary production area of the US Midwest. APSIM accurately reproduced experimental data from the Soybean Free-Air CO2 Enrichment site showing that the CFE declined with increasing drought stress. This resulted from greater radiation use efficiency (RUE) and above-ground biomass production at elevated [CO2] that outpaced gains in transpiration efficiency (TE). Using an ensemble of eight climate model projections, we found that drought frequency in the US Midwest is projected to increase from once every 5 years currently to once every other year by 2050. In addition to directly driving yield loss, greater drought also significantly limited the benefit from rising [CO2]. This study provides a link between localized experiments and regional-scale modeling to highlight that increased drought frequency and severity pose a formidable challenge to maintaining soybean yield progress that is not offset by rising [CO2] as previously anticipated. Evaluating the relative sensitivity of RUE and TE to elevated [CO2] will be an important target for future modeling and experimental studies of climate change impacts and adaptation in C3 crops.
Oil palm production expanded 1.2 million hectares in sub-Saharan Africa since 1990, with expansion accelerating in several heavily forested countries since 2000. Despite a narrative of expansion driven by multinational corporations, we provide evidence of a dynamic non-industrial oil palm production sector linked to a burgeoning informal milling enterprise. Surveys were conducted with oil palm farmers in Cameroon (n = 546), the third largest palm oil producer on the continent with the greatest amount of deforestation due to recent expansion, to determine who is expanding into forest. Seventy-three percent of survey respondents reported clearing forest, the magnitude of which was explained by differences in milling strategies and supply chain integration. Large-scale, non-industrial producers played a disproportionate role in deforestation, many of which were engaged in informal supply chains through the use of non-industrial mills. Farms associated with more clearing tended to use high-yielding seedlings. Even the highest yielding farms, however, averaged only 7.7 tons fresh fruit bunches (FFBs) ha−1 yr−1, well below the potential 20 tons FFBs ha−1 yr−1 yield for Cameroon. We also found a strong relationship between deforestation and land claims. Most farms claimed ownership of their land, although only 5% had official land titles. Conservation challenges in the region arise from land tenure laws that incentivize forest clearing. This study sheds light on the role of informal supply chains in deforestation and highlights the need for strict implementation and enforcement of land use zoning policies.
Food security will be increasingly challenged by climate change, natural resource degradation, and population growth. Wheat yields, in particular, have already stagnated in many regions and will be further affected by warming temperatures. Despite these challenges, wheat yields can be increased by improving management practices in regions with existing yield gaps. To identify the magnitude and causes of current yield gaps in India, one of the largest wheat producers globally, we produced 30 meter resolution yield maps from 2001 to 2015 across the Indo-Gangetic Plains (IGP), the nation's main wheat belt. Yield maps were derived using a new method that translates satellite vegetation indices to yield estimates using crop model simulations, bypassing the need for ground calibration data. This is one of the first attempts to apply this method to a smallholder agriculture system, where ground calibration data are rarely available. We find that yields can be increased by 11% on average and up to 32% in the eastern IGP by improving management to current best practices within a given district. Additionally, if current best practices from the highest-yielding state of Punjab are implemented in the eastern IGP, yields could increase by almost 110%. Considering the factors that most influence yields, later sow dates and warmer temperatures are most associated with low yields across the IGP. This suggests that strategies to reduce the negative effects of heat stress, like earlier sowing and planting heat-tolerant wheat varieties, are critical to increasing wheat yields in this globally-important agricultural region.
Although development organizations agree that reliable access to energy and energy services—one of the 17 Sustainable Development Goals—is likely to have profound and perhaps disproportionate impacts on women, few studies have directly empirically estimated the impact of energy access on women's empowerment. This is a result of both a relative dearth of energy access evaluations in general and a lack of clarity on how to quantify gender impacts of development projects. Here we present an evaluation of the impacts of the Solar Market Garden—a distributed photovoltaic irrigation project—on the level and structure of women's empowerment in Benin, West Africa. We use a quasi-experimental design (matched-pair villages) to estimate changes in empowerment for project beneficiaries after one year of Solar Market Garden production relative to non-beneficiaries in both treatment and comparison villages (n = 771). To create an empowerment metric, we constructed a set of general questions based on existing theories of empowerment, and then used latent variable analysis to understand the underlying structure of empowerment locally. We repeated this analysis at follow-up to understand whether the structure of empowerment had changed over time, and then measured changes in both the levels and likelihood of empowerment over time. We show that the Solar Market Garden significantly positively impacted women's empowerment, particularly through the domain of economic independence. In addition to providing rigorous evidence for the impact of a rural renewable energy project on women's empowerment, our work lays out a methodology that can be used in the future to benchmark the gender impacts of energy projects.
Using agricultural and economic characteristics in African nations as test cases, new research by David Lobell and Marshall Burke demonstrates the use of satellite data to address the long-standing problem of accurate data collection in developing countries. An often cited challenge in achieving development goals aimed at poverty and hunger reduction is the lack of reliable on-the-ground data. Limited or insuffiient data makes it difficult to establish baseline conditions and to assess effectiveness of various aid programs. In the past, researchers and policymakers had to rely on ground surveys, which are expensive, time-consuming, and rarely conducted. This has led to large data gaps in mapping sustainable development goal progress, such as in agricultural and poverty statistics.
