Jon Foley: How to Feed Nine Billion and Keep the Planet Too
›October 12, 2011 // By Geoffrey D. Dabelko
Jon Foley of the University of Minnesota’s Institute on the Environment is a food security rock star, plain and simple. And he deserves that lofty status in part because he explains our complex 21st century agriculture challenges in such a clear and accessible fashion. See him present (like in the TEDx video above), and you are left wishing all scientists would drop in on the “how to make your work understandable” class that Foley must have aced.
Foley brought that clarity of presentation, mixed with self-deprecating humor, to this past week’s inaugural South by Southwest (SXSW) Eco conference in Austin, Texas. Foley said we must meet three big challenges in the realm of agriculture:- Feeding the population today: One in seven of the world’s seven billion people do not know where their next meal is coming from.
- Feeding the future population: The planet is expected to reach more than nine billion people in just 39 years (and may still continue to grow beyond nine billion, rather than leveling off as expected until recently).
- Farming the planet sustainably: We are a long way from achieving sustainable agriculture, given overuse of fertilizers, soil erosion and degradation, deforestation (leading to loss of biodiversity), and energy-intensive practices (producing excessive carbon emissions).
But Foley and his colleagues retain their scientific union cards while suggesting specific ways the world might meet the three food security goals listed above. In what must be considered the academic equivalent of a walk-off grand slam, they will be featured as next week’s cover story in Nature and a more accessible derivative in the November issue of Scientific American.
“Today, humans are farming more of the planet than ever, with higher resource intensity and staggering environmental impacts, while diverting an increasing fraction of crops to animals, biofuels and other nonfood uses,” Foley et al. write in Nature. “Meanwhile, almost a billion people are chronically hungry. This must not continue: the requirements of current and future generations demand that we transform agriculture to meet the twin challenges of food security and environmental sustainability.”
Their four-step plan in brief:- Slow agricultural expansion to stop deforestation and the huge ecological cost that stems from expanding into new lands, often to grow animal feed rather than food for direct human consumption.
- Grow more food on the acres currently under cultivation. The attention, resources, and innovation applied to the best-producing farms need to also be turned on the least productive farms, where rates as low as 20 percent of potential yields are the norm.
- Improve the resource efficiency of agriculture, through better water use, for example. Places like India, where the energy to pump groundwater is effectively free, are very inefficient in the use of water per calorie grown.
- Close “diet gaps,” where only 60 percent of what is grown is actually for human consumption (the rest for animals and fuel), and reduce food waste, whether it is spoilage on the way to market or the excesses of a food industry that leaves so much uneaten.

Watch: First Impressions From the Inaugural SXSW Eco Conference
›October 6, 2011 // By Schuyler NullOur director, Geoff Dabelko, provides a brief update from South by Southwest’s (SXSW) first Eco conference, being held in Austin, Texas this week:
Bill Ritter, former governor of Colorado, was impressive in an interview with Bryan Walsh of Time magazine, seamlessly alternating between technical and policy questions about energy security.
Ned Breslin, CEO of Water for People, provided some real talk, challenging the notion that it’s “easy” to provide needy populations with freshwater. It’s not as simple as “$25 saves a life,” he said. Providing long-term, sustainable water and sanitation solutions to people around the world requires a great deal of hard work, particularly on financing and ownership questions.
Finally, Jon Foley of the University of Minnesota’s Institute on the Environment presented a five-step response to what he called today’s three main food challenges: providing enough to feed today’s population, tomorrow’s (an estimated nine billion people by 2050), and doing it all in a sustainable fashion. The Institute on the Environment publishes an almost-quarterly magazine, Momentum, whose work we’ve featured before on New Security Beat (here, here, and here), and, incredibly, is available, delivered to your house, for FREE. Highly recommended.
Stay tuned for more updates from SXSW, including the ECSP-supported panel, “Three Great Ideas That Won’t Be On the Rio+20 Agenda.” -
Watch: Dennis Taenzler on Four Key Steps for REDD+ to Avoid Becoming a Source of Conflict
›The UN Program on Reducing Emissions from Deforestation and Forest Degradation (REDD) provides financial incentives to developing countries to conserve their forests and invest in low-carbon pathways to sustainable development. However, it may also be a potential new source of conflict, says Dennis Taenzler, a senior project manager at adelphi in Berlin, who works on climate and energy policies as well as peace and conflict issues.

El Niño, Conflict, and Environmental Determinism: Assessing Climate’s Links to Instability
›October 5, 2011 // By Schuyler Null
A recent Nature article on climate’s impact on conflict has generated controversy in the environmental security community for its bold conclusions about links between the global El Niño/La Niña cycle and the probability of intrastate conflict.

SXSW Eco Panel: Three Great Ideas That Won’t Be On the Rio+20 Agenda
›September 30, 2011 // By Schuyler NullSouth by Southwest (SXSW) – the popular music, film, and alternative showcase – is moving into the green space with its first ever “eco” conference, kicking off next week, October 4, with more than 50 panels on “solutions for a sustainable world.” There’s one in particular though you should tune into: “Three Great Ideas that Won’t Be On the Rio Agenda,” featuring Geoff Dabelko, director of the Wilson Center’s Environmental Change and Security Program; Roger-Mark De Souza, vice president of research and director of the climate program at Population Action International; and Aimee Christensen, CEO of Christensen Global Strategies.
The panel will feature discussion on three issues that will likely not be on the table at the Rio+20 UN Conference on Sustainable Development next year: integrated population, health, and environment development programs, climate adaptation as a path to peacebuilding, and how to get the private sector better involved in helping cope with climate change.
If you’re traveling down to Austin, “Three Great Ideas” is scheduled for Thursday, October 6 at 10am CST; if not, stay tuned for webcast information! -
Remembrance: Wangari Maathai, Nobel Peace Prize Winner, Linked Environment and Conflict
›September 26, 2011 // By Schuyler NullSad news today as Wangari Maathai, the first African woman and the first environmentalist to win the Nobel Peace Prize, has passed away in Nairobi. The Green Belt Movement, which Maathai founded in 1977, has planted over 30 million trees and advocates for what Maathai called the three essential components of a stable society: sustainable environmental management, democratic governance, and a culture of peace. [Video Below]
“Almost every conflict in Africa you can point at has something to do with competition over resources in an environment,” said Maathai during her visit to the Wilson Center in 2009:Unless you deal with the cause, you are wasting your time. You can use all the money you want for all the years you want; you will not solve the problem, because you are dealing with a symptom. So we need to go outside that box and deal with development in a holistic way.
Maathai’s message was molded from her experiences in Kenya and across sub-Saharan Africa in general. She was not shy about condemning African leaders and advocating for women in the political space. In ECSP Report 12, she wrote, “I come from a continent that has known many conflicts for a long time. Many of them are glaringly due to bad governance, unwillingness to share resources more equitably, selfishness, and a failure to promote cultures of peace.”
Importantly, though, Maathai advocated for addressing these issues in concert, not separately. She said at the Wilson Center:I can’t say, ‘Let us deal with governance this time, and don’t worry about the resources.’ Or, ‘Don’t worry about peace today, or conflicts that are going on; let us worry about management of resources.’ I saw that it was very, very important to use the tree-planting as an entry point.
A Message to the World
Some raised questions when Maathai won the Nobel Peace Prize in 2004 – the first awarded to someone from the environmental field – but the recognition was more than deserved, wrote Environmental Change and Security Program (ECSP) Director Geoff Dabelko on Grist:Maathai is on the front lines of the struggle over natural resources that fuels conflicts across the world. While there is no dramatic footage of tanks rumbling across borders or airplanes flying into buildings, the everyday fight for survival of those who depend directly on natural resources – forests, water, minerals – for their livelihoods is at the heart of the battle for peace and human security.
Maathai explained in Report 12 that she thought her winning of the prize was intended as a message to the world to “rethink peace and security.”
…
Elevating such a strong Southern voice – and one whose elephant’s skin bears the scars of the fight for peace – is a noble choice.
The Nobel Committee “wanted to challenge the world to discover the close linkage between good governance, sustainable management of resources, and peace,” she wrote. “In managing our resources, we need to realize that they are limited and need to be managed more sustainably, responsibly, and accountably.”

Carl Haub, Yale Environment 360
What If Experts Are Wrong On World Population Growth?
›September 22, 2011 // By Wilson Center StaffThe original version of this article, by Carl Haub, appeared on Yale Environment 360.
In a mere half-century, the number of people on the planet has soared from 3 billion to 7 billion, placing us squarely in the midst of the most rapid expansion of world population in our 50,000-year history – and placing ever-growing pressure on the Earth and its resources.
But that is the past. What of the future? Leading demographers, including those at the United Nations and the U.S. Census Bureau, are projecting that world population will peak at 9.5 billion to 10 billion later this century and then gradually decline as poorer countries develop. But what if those projections are too optimistic? What if population continues to soar, as it has in recent decades, and the world becomes home to 12 billion or even 16 billion people by 2100, as a high-end UN estimate has projected? Such an outcome would clearly have enormous social and environmental implications, including placing enormous stress on the world’s food and water resources, spurring further loss of wild lands and biodiversity, and hastening the degradation of the natural systems that support life on Earth.
It is customary in the popular media and in many journal articles to cite a projected population figure as if it were a given, a figure so certain that it could virtually be used for long-range planning purposes. But we must carefully examine the assumptions behind such projections. And forecasts that population is going to level off or decline this century have been based on the assumption that the developing world will necessarily follow the path of the industrialized world. That is far from a sure bet.

Broadening Development’s Impact: From Sustainability to Governance and Security
›John Drexhage and Deborah Murphy’s UN background paper, “Sustainable Development: From Brundtland to Rio 2012,” looks at how “sustainable development” has evolved since the 1987 Brundtland Report first brought the concept to the forefront of the international community’s attention. Drexage and Murphy write that climate change has become a “de facto proxy” for sustainable development and they offer various recommendations for how policymakers and institutions can better integrate social and economic issues into a sustainable development framework. Considering that “increasing consumption, combined with population growth, mean that humanity’s demands on the planet have more than doubled over the past 45 years,” the authors conclude that “the opportunity is ripe” to bring “real systemic change” to how the world thinks about – and acts on – sustainable development.The World Bank’s World Development Report 2011 makes an argument for “bringing security and development together to put down roots deep enough to break the cycles of fragility and conflict.” The report gives an overview of the “interconnections among security, governance, and development” and offers recommendations on how understanding and addressing them can end cycles of violence. Just as Drexhage and Murphy point to population changes as a challenge for sustainable development, the World Bank notes that growing urbanization has “increased the potential for crime, social tension, communal violence, and political instability” locally while a threefold increase in refugees and internally displaced persons over the past 30 years has put strains on regional relations around the world. Though the report acknowledges that there’s no quick fix to any of these problems, the conclusion underlining the report’s findings is that “strengthening legitimate institutions and governance to provide citizen security, justice, and jobs is crucial to break cycles of violence.”
