Outside of China, the world now has more food insecure and nutrient deficient people than it had a decade ago, and the prevalence of obesity-related diabetes, high blood pressure and cardio-vascular diseases is increasing at very rapid rates. Expanded food production has done little to address the fact that between one-third and one-half of all deaths in children under five in developing countries are still related to malnutrition.

“With only three years away from the Millennium Development Goals deadline, this is a terrible track record,” said food and nutrition policy expert Per Pinstrup-Andersen at FSE's Global Food Policy and Food Security Symposium Series last week.  

Pinstrup-Andersen, the only economist to win the World Food Prize (the ultimate award in the food security field), has dedicated his career to understanding the linkages between food, nutrition, and agriculture. What is driving persistent food insecurity and malnutrition in a food abundant world?

Poor food supply management is part of the problem. According to the United Nations Food and Agricultural Organization (FAO), 20-30% of food produced globally is lost every year. That’s enough to feed an additional 3-3.5 billion people.

Biofuels production, such as jatropha in Africa, now competes with food for land, and climate change is already negatively impacting crop yields in regions straddling the equator—with major implications for food supply.

For low-income consumers in both the U.S. and developing countries increasing and more volatile food prices, such as those seen in 2007, are also driving food insecurity. Poor consumers respond by purchasing cheaper, less nutrient food, and less of it.

Nutritional value chain

Consensus is developing—at least rhetorically—among national policymakers and international organizations that investments in agricultural development must be accelerated. Members of the G8 and G20 have committed $20 billion in international economic support for such investments and some developing countries such as Ethiopia and Ghana are planning large new investments.

While most of these recent initiatives focus on expanded food supplies, there is an increasing understanding that merely making more food available will not assure better food security, nutrition, and health at the household and individual levels.

“It matters for health and nutrition how increasing food supplies are brought about and of what it consists,” said Pinstrup-Andersen. “We need to turn the food supply chain into a nutritional value chain.”

Diet diversity is incredibly important for good nutrition. Agricultural researchers and food production companies need to look at a number of different commodities, not just the major food staples, said Pinstrup-Andersen.

“The Green Revolution successfully increased the production of corn, rice, and wheat, increasing incomes for farmers, and lowering prices for consumers, but now it is time to invest in fruits, vegetables and biofortification to deal with micronutrient deficiency,” said Pintrup-Andersen.

Biofortification, the breeding of crops to increase their nutritional value, offers tremendous opportunity for dealing with malnutrition in the developing world, but is not widely available.

This is particularly important for areas in sub-Saharan Africa where between one and three and one and four people are short in calories, protein, and micronutrients. Obesity is actually going up in these countries with the introduction of cheap, processed, energy-dense foods (those high in sugar and fat) contributing to the diabetes epidemic.

Pathways to better health

The path to better health and nutrition must look beyond the availability of food at affordable prices, clean water, and good sanitation, and consider behavioral factors such as time constraints for women in low-income households.

“Field studies have shown time and time again that one of the main factors preventing women from providing themselves and their families with good nutrition is time,” explained Pinstrup-Andersen.

He told the story of a woman in Bolivia too burdened with farm and household responsibilities to take the time to breastfeed her six-month old daughter. Enhancing productivity in activities traditionally undertaken by women could be a key intervention to improving good health and nutrition at the household level.

Access is another issue. A household may be considered food secure, in that sufficient food may be available, but food may not be equally allocated in the household.

“If we focus on the most limiting constraint we can be successful,” said Pinstrup-Anderen. “But we must tailor our response to each case.”

For sub-Saharan Africa, this includes investments in rural infrastructure, roads, irrigation systems, micronutrient fertilizer, climate adaptation strategies, and other barriers holding back small farmers.

Fortunately, there has been a renewed attention to the importance of guiding food system activities towards improved health and nutrition. The Global Agriculture and Food Security Program (GAFSP), which facilitates the distribution of some of the G8 and G20 $20 billion commitments, prescribes that country proposals for funding of agricultural development projects must show a clear pathway from the proposed agricultural change to human nutrition.

“But it’s not going to be easy to implement good policies,” warned Pinstrup-Andersen. “There are few incentives in government for multidisciplinary problem solving. The economy is set up around silos and people are loyal to their silos. Agricultural and health sectors are largely disconnected in their priorities, policy, and analysis."

Incentives must change to encourage working across ministries and disciplines to identify the most important health and nutrition-related drivers of food systems, impact pathways, and policy and program interventions to find win-wins for positive health and nutrition.

The film "Silent Killer: The Unfinished Campaign Against Hunger," hosted by NPR's Scott Simon, offers a compelling examination of both the problem and solutions surrounding world hunger. The program aired on PBS station KQED/San Francisco on Wednesday, November 2nd at 11:00 p.m.

SEATTLE - There are a billion hungry people in the world. Fifteen thousand children-the equivalent of five times the victims of the World Trade Center bombings-die each day of hunger. Yet it doesn't have to be this way. We can end hunger-if we make a commitment to doing so. The new one-hour documentary Silent Killer: The Unfinished Campaign Against Hunger shows how it can be done. Shot on location in the United States, South Africa, Kenya, Rome, Mexico and Brazil, Silent Killer examines both the problem of hunger and solutions. The documentary and its companion Web site (www.SilentKillerFilm.org) will provide viewers with inspiration and information to become part of the effort to end hunger.

Produced by Hana Jindrova and John de Graaf (Affluenza, Escape from Affluenza), in association with KCTS/Seattle Public Television, Silent Killer will air on several California public television stations as follows:

KTEH/ San Jose: Sunday, October 16 at 5:00 p.m. (please confirm).

KOCE/ Huntington Beach: Sunday, October 23 at 4:00 p.m.

Narrated by National Public Radio's Scott Simon, the film begins in South Africa's Kalahari Desert, where razor-thin Bushmen use the Hoodia cactus to fend off hunger. But now, a drug firm has patented the Hoodia's appetite-suppressant properties and is using it to make a diet product for obese Americans and Europeans. Hoodia is a metaphor for a world where some people die from too much food, but millions more die from too little.

We discover how serious the problem is in Kenya as we meet Jane Ininda, a scientist who is trying to make agriculture more productive in her country, while her own brother, Salesio, barely survives the drought, poor soils and pests that constantly threaten his crops. Through powerful stories, we come to understand the dimensions of the hunger crisis.

At the World Food Summit in Rome, we learn how activists have been working to end hunger since President John Kennedy declared war on it in 1963. But today, America's commitment to food security is less clear. In fact, world financial commitments to hunger research are now in decline.

But Silent Killer does not leave viewers feeling helpless. A visit to Brazil finds a nation energized by a new campaign called FOME ZERO-Zero Hunger. In the huge city of Belo Horizonte, we meet a remarkable leader and see how, under the programs she supervises, the right to food is guaranteed to all. In the countryside, we are introduced to the Landless Peasants' Movement, which is giving hope to millions of hungry Brazilians.

Can we end hunger, or will it always be with us? Why should we try? What will it take? What are we doing now? Can biotechnology play a role, and if so, how? Is hunger just a problem of distribution, or do we still need to produce more and better crops? These are the questions considered in this exquisitely photographed documentary.
