Innovation of the Month: Cereal Banks Protect Against Famine and Empower Women Across the Sahel

Share

By Caitlin Aylward

Drought and high food prices in 2012 threatened the food security of over 18 million people in the Sahel Region of Africa, which includes parts of Chad, Niger, Mali, Mauritania, Burkina Faso, Senegal, Gambia, Cameroon, and northern Nigeria. The Sahel is prone to drought, and is becoming increasingly so with climate change. Consequently the people in this region are experiencing more frequent bouts of food insecurity and malnutrition.

Fortunately, organizations such as the World Food Program (WFP) and Care are joining forces to create all-women-managed cereal banks in villages throughout the Sahel that not only help protect against seasonal famine, but also empower women as agents of food security in their communities.

Cereal banks are community-led grain distribution projects that store grain after harvests, and then loan grain when food is scarce during what is known as the ‘lean season.’

In 2009, WFP and Care established exclusively women-operated cereal banks to help ensure the availability of grain supplies year round. These community cereal banks loan grain below market price, helping protect against market speculation, and enabling even the poorest women to purchase food for their families during times of scarcity. The women are expected to repay the loans, but at very low interest rates and only after they have harvested their own crops.

Camu Camu: A Little Fruit that Packs a Big Punch

Share

By Eleanor Fausold

Sometimes the best things come in small packages. Camu camu (Myrciaria dubia) is a tiny fruit native to the Amazon region of South America that is rising in popularity, as both an element in local treats and a main component in dietary supplements. Although its high level of acidity once made it unpopular for consumption, the fruit is now valued for its exceptionally high vitamin C content and is, consequently, growing in demand in health-food stores around the world.

Also known as camocamo in Peru and cacari in Brazil, among other names, the camu camu tree can grow up to 40 feet high. The species thrives in swamps along rivers and lakes such as the Rio Mazán near Iquitos, Peru, and in Amazonian Brazil and Venezuela. The base of the camu camu’s trunk is frequently underwater, and the tree’s lower branches are often submerged for long periods during the rainy season.

Despite its frequent submersion, the camu camu tree produces fragrant flowers with tiny white petals and tiny fruits that turn from yellow to a maroon or purple-black color as they ripen. In the right growing conditions, a single tree can produce as many as 1,000 fruits per year, which are harvested by boat.

Known for its extremely high vitamin C content (half-ripe fruits have been found to contain 1,950 to 2,700 milligrams per 100 grams of edible fruit, an amount greater than that found in 50 oranges), the camu camu fruit has a very acidic taste. In fact, until fairly recently, the fruit was used almost exclusively as fish bait and the tree, when dead, was used as a source of firewood.

Global Food Prices Continue to Rise

Share

By Sophie Wenzlau

Continuing a decade-long increase, global food prices rose 2.7 percent in 2012, reaching levels not seen since the 1960s and 1970s but still well below the price spike of 1974. Between 2000 and 2012, the World Bank global food price index increased 104.5 percent, at an average annual rate of 6.5 percent.

The price increases reverse a previous trend when real prices of food commodities declined at an average annual rate of 0.6 percent from 1960 to 1999, approaching historic lows. The sustained price decline can be attributed to farmers’ success in keeping crop yields ahead of rising worldwide food demand. Although the global population grew by 3.8 billion or 122.9 percent between 1961 and 2010, net per capita food production increased by 49 percent over this period. Advances in crop breeding and an expansion of agricultural land drove this rise in production, as farmers cultivated an additional 434 million hectares between 1961 and 2010.

Food price volatility has increased dramatically since 2006. According to the United Nations Food and Agriculture Organization (FAO), the standard deviation—or measurement of variation from the average—for food prices between 1990 and 1999 was 7.7 index points, but it increased to 22.4 index points in the 2000–12 period.

Although food price volatility has increased in the last decade, it is not a new phenomenon. According to World Bank data, the standard deviation for food prices in 1960–99 was 11.9 index points higher than in 2000–12. Some price volatility is inherent in agricultural commodities markets, as they are strongly influenced by weather shocks. But the recent upward trend in food prices and volatility can be traced to additional factors including climate change, policies promoting the use of biofuels, rising energy and fertilizer prices, poor harvests, national export restrictions, rising global food demand, and low food stocks.

Perhaps most significant has been an increase in biofuels production in the last decade. Between 2000 and 2011, global biofuels production increased more than 500 percent, due in part to higher oil prices and the adoption of biofuel mandates in the United States and European Union (EU). According to a 2012 study by the University of Bonn’s Center for Development Research, if biofuel production continues to expand according to current plans, the price of feedstock crops (particularly maize, oilseed crops, and sugar cane) will increase more than 11 percent by 2020.

Innovation of the Month: Food Fermentation for Biopreservation

Share

By Brandon Pierce

Although the word “bacteria” is usually associated with sickness and disease, it is the driving force behind fermentation, a food process on which humans have relied for millennia. Some of the earliest recorded instances of fermentation come from East Asia where, according to William Shurtleff, founder of the SoyInfo Center, the process was used as early as 300 BCE to ferment soybeans.

Fermentation historically has had two purposes. Foods undergoing the fermentation process went through remarkable changes in taste, basically allowing for the creation of new foods. Fermentation also served as a way to prevent foods from spoiling. It is referred to as a biopreservation method, or a way to preserve foods using beneficial microorganisms.

In biopreservation, beneficial bacteria are used to prevent food spoilage and get rid of harmful pathogens. Lactic acid bacteria (LAB) are probably the most commonly used due to their unique properties and because they are harmless to humans. As LABs compete for nutrients with other bacteria, they release antimicrobials that stop spoilage and inhibit the growth of potentially harmful pathogens.

In functioning as an effective biopreservative, bacteria do not necessarily have to also start the process of fermentation. Generally, bacteria are selected either for their metabolic properties, which cause fermentation, or for their antimicrobial activity, which is important for food preservation. LAB can be used for both.

As household incomes, urban populations, and overall food consumption in China continue to rise, the country faces serious problems of food waste, natural resource scarcity, and overflowing landfills. Currently, over 200 billion Yuan’s (US$32 billion) worth of food is thrown away annually nationwide, even as 128 million Chinese live below the poverty line and often lack sufficient food.

In November 2012, the Rome Film Festival premiered “Back to 1942,” which tells the story of a famine in the central Henan Province during World War II.  The film spurred discussion about the Great Famine, in which 45 million people starved as a consequence of the Great Leap Forward, the country’s modernizing effort back in the late 1950s. Today, the Great Famine still affects the psyche of the average Chinese citizen—higher average incomes have led, in many cases, to overconsumption and waste of food.

Documentary Sheds New Light on Thriving Community Gardens

Share

By Carol Dreibelbis

There are an estimated 18,000 community gardens in the United States and Canada, according to the group Why Hunger, and thousands more worldwide. Designing Healthy Communities, a project of the nonprofit Media Policy Center, notes that community gardens “can play a significant role in enhancing the physical, emotional, and spiritual well-being necessary to build healthy and socially sustainable communities.”

In her 2011 documentary A Community of Gardeners, filmmaker Cintia Cabib offers an intimate look at the vital role that seven community gardens play in Washington, D.C.

At Common Good City Farm, a work-exchange program enables local residents to volunteer in the garden in exchange for fresh produce. One volunteer explains just how important the garden is for her: “The garden plays a big role in my life because it feeds me. I live out of this garden: whatever I get every Wednesday, that’s what feeds me for the whole week.”

At Fort Stevens Community Garden, an organic garden run by the National Park Service, immigrant gardeners from around the world grow fruits and vegetables that are native to their homelands in Africa, Latin America, and the Caribbean. The Park Service also provides land and water for the Melvin Hazen Community Garden, which was once a World War II victory garden.

Iguana Meat Is on the Table

Share

By Victoria Russo

Green and scaly, with a mouth full of sharp teeth, the iguana might not look like a nutritious meal. But as the iguana population surpasses the human population in Puerto Rico—destroying gardens, digging holes under houses, and blocking roads and runways—residents are beginning to use the animal for meat. Although there is, as of yet, little global demand for this untraditional dish, Puerto Ricans are looking to international meat markets to support local pest control.

Iguanas originated in Central and South America and were first brought to Puerto Rico in the 1970s to be sold as pets. The reptiles reproduce quickly, with mature females laying up to 70 eggs annually. Once iguanas entered the wild in Puerto Rico, the population quickly spiraled out of control. The animals are well camouflaged and very fast, which makes them difficult to catch.

By using iguanas for food, Puerto Ricans have found an effective way to control the reptile’s exploding population. Iguana meat has been compared to a slightly sweeter version of chicken, and common recipes include stews, tacos, and roasts. Iguana eggs are edible as well, and are said to have a rich, cheesy flavor. Puerto Rico is not the only place using iguanas for food: in Central and South America, the meat is seen as a delicacy. Nutritionally, it is rich in minerals, such as calcium and magnesium, and has more protein than chicken. If Puerto Ricans develop a taste for the meat, iguana could become a staple food source for the island.

Some other countries, including El Salvador and Mexico, already have export industries for iguana meat. Between 2001 and 2008, the United States imported more than 9,071.85 kilograms of the meat to meet the low but rising demand for consumption by humans. According to the Dallas Observer, iguana meat can go for up to $50 per pound in some U.S. markets. The business can be so lucrative that people in some countries have established iguana farms to ensure consistent supply. The production of iguana has resulted in markets for other products as well: iguana skin is used to make leather, while iguana oil is used for medicinal purposes (for example, for rheumatism, to clear up bruises, and as an aphrodisiac).

The production of iguana meat and other products could benefit Puerto Rico in multiple ways: it could protect other Puerto Rican fauna, offer new employment opportunities, and boost domestic food security.

Students Protest New, Healthier School Lunches

Share

By Carol Dreibelbis

Thanks to the Healthy, Hunger-Free Kids Act of 2010, schools across the United States are serving healthier school lunches this academic year. School lunches must meet new nutritional guidelines—such as including fruits and vegetables and limiting fats and sodium—for schools to receive extra federal lunch aid. Calories counts are also restricted: high school, middle school, and elementary school lunches must now be no more than 850, 700, and 650 calories, respectively. Although nutrition and health advocates celebrate this change, a recent article in The New York Times indicates that many students feel differently.

Students in districts around the country have responded to the healthier lunches with boycotts and strikes. According to Shawn McNulty, principal at Mukwonago High School in Wisconsin, participation in the school lunch program had fallen 70 percent as a result of student action. “There is a reduction in nacho chips, there is a reduction in garlic bread, but there’s actually an increase in fruits and vegetables,” Mr. McNulty said. “That’s a tough sell for kids, and I would be grumbling, too, if I was 17 years old.” Students are also throwing away more food in New York City and elsewhere.

Food service directors are using a variety of strategies to encourage students to eat fruits and vegetables, including asking teachers to discuss healthy food in class, giving out free samples, and educating students about where their food comes from and how it is produced. But, schools may simply need to wait for students to grow accustomed to new menu options: according to William J. McCarthy, professor of public health and psychology at the University of California, Los Angeles, children must be exposed to vegetables 10 to 12 times before they eat them on their own. “If our task is to get young kids to eat more fruits and vegetables, we have to be willing to put up with the waste,” he said.

New Rice for Africa: Shades of Both a Green Revolution and Food Sovereignty

Share

Daniel Bornstein is a junior at Dartmouth College majoring in Anthropology and Environmental Studies. A contributor to Nourishing the Planet and PolicyMic.com, he is currently studying in the Gambia with St. Mary’s College of Maryland’s Promoting Educational and Cultural Exchange program.

JAMBUR, The Gambia—The dissemination of the high-yielding New Rice for Africa (NERICA) seeds has sparked contention that is a microcosm for a central debate in global agricultural development: does Africa need its own Green Revolution, an effort that 50 years ago saw dramatic productivity increases through the use of new crop technologies in Asia and Latin America?

NERICA, developed by 2004 World Food Prize winner Dr. Monty Jones, is being promoted by the Africa Rice Center mainly in West African countries where rice is a staple food. It is a cross between an Asian variety, responsible for the high yield, and an African variety, which ensures its local adaptability.

West African governments have touted NERICA as a hallmark of a new Green Revolution and as a path to boosting rice self-sufficiency, especially after the 2008 food price spike exposed the dangers of import dependence. On the other side, advocates of “food sovereignty”—centered on farmers’ control over food systems—have voiced strong opposition. The advocacy organization GRAIN has labeled NERICA a “trap for small farmers” who will become vulnerable to expensive chemical fertilizers and seeds, a situation widely cited by critics of the 1960s Green Revolution.

What I’ve found in Jambur, which in 2002 became the first Gambian village to access the new crop, is a much more nuanced picture, one that in fact incorporates elements of each side of the debate. This suggests what a tactical misstep it would be for food sovereignty loyalists to completely remove themselves from engaging with a new variety just because it has become embedded in the discourse of a new Green Revolution.

I have observed, in one respect, an outcome that reveals the dangers of making small-scale farmers dependent on high-input seeds: the expensive price of chemical fertilizer. Farmers here say that in most years they have applied fertilizer at the rate of 4 bags of NPK and 2 of urea per hectare, the amount recommended to them by the National Agricultural Research Institute. But this year fertilizer’s price has jumped and they are cutting back usage by more than half, and seeing yields shrink as a result.

Here lies the problem with the notion that higher yields alone will end hunger in developing countries. A standard mantra talks about addressing the “yield gap” whereby resource-poor farmers are achieving lower yields than farmers of the same crop in the world’s most productive regions. But the yield difference is due in large part to the inability of African farmers to access the very inputs that enable such high production in wealthy countries. So boosting yields simply to close a “yield gap” may involve jeopardizing farmers’ own livelihoods, which is not the right path for agricultural development, especially since it is small farmers themselves who are the most vulnerable population.

Despite that downside, alternative food movements can find in NERICA a characteristic that is a pillar of their agenda: ‘seed sovereignty,’ or farmers’ right to save their own seeds, as opposed to having to purchase seeds. Unlike the hybrid seeds of the Green Revolution, farmers can harvest and re-plant NERICA every season. In Jambur, they are trained on how to harvest the highest quality seeds by the village’s resident farmer expert on NERICA, Omar Bojang, who claims that “nobody in The Gambia knows more about NERICA” than himself—a sign of the farmer-to-farmer knowledge dissemination that, it turns out, is also a top priority of food sovereignty folks. So as outspoken critical voices invoke Vandana Shiva’s notions of “biopiracy” to warn about the African Green Revolution’s erosion of farmers’ control over seeds, we would do well to remember that this simply doesn’t apply to NERICA.

If the movement for a new model for global agriculture becomes intent on attacking anything that has ever been praised by proponents of an African Green Revolution, then it risks missing opportunities to influence the implementation of new varieties in ways that benefit small-scale farmers. Nowhere is this idea better encapsulated than in anthropologist Glenn Stone’s concept of a “science of the gray.”

“This is an odd corner for researchers ethically committed to the welfare of Third World farmers to have painted themselves into—opposing potentially beneficial agricultural strategies or technologies because they might impede a complete transformation of the agricultural system,” Stone writes in a 2005 article. “If the complete transformation never comes, one has relinquished the ability to mitigate the excesses of the extant system.”

Applying this wisdom to NERICA, we must realize that the thrust toward another Green Revolution, associated as it is with some of the most powerful institutions in the world, isn’t going away any time soon. But there are ways to “mitigate the excesses”—pushing for more research on agro-ecological production, and training farmers in seed production and in farmer-to-farmer dissemination.

I’ve heard the argument from activists that playing by the rules of the pro-Green Revolution institution risks co-optation and ultimately dissolution of reform movements. But I’d say that contributing to the prevailing system—no matter how strongly you disagree with its underlying ideals—can actually raise the profile of alternative models, if only because you’re given the space to demonstrate their success.

So as the debate over an African Green Revolution continues to rage, it’s important to keep in mind that the reality will almost certainly lay in the “gray” area, rather than exactly matching one side’s ideological perspective.

In your own work, where have you encountered examples of the “gray” area that may characterize new agricultural technologies? Share them with us in the comment section below.
