Ohio State Researcher: Global Hunger May Be Double Previous Estimates

February 23, 2012

COLUMBUS, Ohio -- A household food and nutrition survey developed in part by an Ohio State University researcher is uncovering a clearer picture of hunger and malnutrition throughout the world.

Although the United Nations' Food and Agriculture Organization (FAO) has in the past estimated that 1 billion people in the world go hungry or are malnourished, the surveys being used now, said Hugo Melgar-Quiñonez, indicate the number may be double that.

"The problem is much larger than we can imagine," said Melgar-Quiñonez, who was asked to report on a portion of the project in January at the International Scientific Symposium on Food and Nutrition Security Information in Rome. Melgar-Quiñonez is food security specialist with Ohio State University Extension and also has an appointment with the Ohio Agricultural Research and Development Center.

The survey, called ELCSA (for Escala Latinoamericana y Caribeña de Seguridad Alimentaria), is based on the food security survey used in the United States. It was developed by Melgar-Quiñonez and researchers from the University of Antioquia in Colombia; the University of Campinas in Brazil; Yale University; and the U.S. Department of Agriculture's Economic Research Service. Launched in 2007 in Colombia and Brazil, ELCSA is currently being used in a dozen countries in Latin America, and translations are being developed in other languages for use in other parts of the world.

Melgar-Quiñonez hopes that widespread use of the survey will help organizations such as FAO develop a better estimate of world hunger and assist policymakers in each country design better ways of combatting hunger and malnutrition.

"There are several ways to measure hunger, but each has its drawbacks," said Melgar-Quiñonez, who is also an associate professor of human nutrition in Ohio State University's College of Education and Human Ecology. The most recent method used by FAO, for example, compared how much food a nation produced or imported, minus the amount of food exported, estimated as waste or used as livestock feed. That information is translated into calories of food available in the nation, which was then divided by the population (adjusted for the number of children, women, men or the elderly). If the calorie level of food available to the average person is too low, the numbers are used to estimate the number of people who are "food insecure."

"But that doesn't tell you anything about who is the most vulnerable in a population," Melgar-Quiñonez said. "What regions in a country are hit hardest? Are women or children going hungry at greater rates? And, focusing on calories alone doesn't tell you anything about the quality of the calorie -- the nutrients available to the population. Also, this type of estimate is also based on the information each country provides. Some nations don't have the resources to be able to collect such information even every five years. So, it's really an incomplete picture."

The survey asks participants a series of questions regarding their household food situation in the previous three months. For example, it asks if the household had run out of food in that time period because of a lack of money or other resources, or if, for the same reason, any adult or child in the household had to skip meals or reduce portion sizes. Other questions ask whether the household could afford a nutritious, varied diet, and how frequently the household experienced such situations.

Development of ELCSA began about 10 years ago when both Brazil and Colombia wanted to set up methods to collect food insecurity data.

"For the first time in history, we had national food security data from two Latin American countries, but it wasn't comparable because they weren't using the same scale," Melgar-Quiñonez said. "With ELCSA, we merged the two surveys -- what we as a group wanted was one scale, the same for all countries."

ELCSA is similar to the U.S. Household Food Security Survey Module used by the U.S. Department of Agriculture's Economic Research Service (http://www.ers.usda.gov/Briefing/FoodSecurity/).

"It's this measurement that shows that single mothers sometimes have three times the national rate of food insecurity, or Hispanic households have double the rate," Melgar-Quiñonez said. "We can identify groups at higher risk, then target programs to help them."

 

Part of Melgar-Quiñonez's work has been to analyze the validity of the survey. In 2010, he received an FAO Research Award -- one of just five given globally -- for his work in comparing the performance of the tool in Mexico, Colombia and Guatemala.

"We found some differences -- we need to work on some issues to make ELCSA an even better tool," he said. "We have offered regional workshops -- five in Central America in 2010 and five more in South American countries in 2011. We want everyone to measure exactly the same way."

In fact, Melgar-Quiñonez just returned from a week in his home country of Guatemala doing some consulting on ELCSA. At a press conference, he presented the most current data on food insecurity for that country. ELCSA will also be used to evaluate the national program against hunger in Guatemala.

Currently, at least some application of ELCSA has been adopted in Mexico, Guatemala, El Salvador, Nicaragua, Colombia, Ecuador, Bolivia, Paraguay, Peru, Brazil, Uruguay, Haiti, with Dominican Republic, Cuba, Venezuela, Chile and Argentina considering beginning use this year. In addition, translations -- some of which are being done by Melgar-Quiñonez's graduate students and recent graduates -- are under way for use of the tool in Albania, southern China, Ghana, Uganda, Palestinian territories and Indonesia. The goal, Melgar-Quiñonez said, is to document the severity of hunger and malnutrition in different populations, allowing policy-makers to develop strategies to help those most at risk.
