Comparison between Experience-Based and Household-Undernourishment Food Security Indicators: A Cautionary Tale

Area of Science:

• Agricultural Economics
• Public Health Nutrition
• Socioeconomics

Background:

• Food security measurement relies on various indicators, often used interchangeably, potentially leading to policy misinterpretations.
• Discrepancies in indicator selection can affect the accurate assessment of food insecurity prevalence, drivers, and policy impacts.

Purpose of the Study:

• To compare the Latin America Food Security Scale (ELCSA) and the household undernourishment indicator.
• To analyze discrepancies in measuring food insecurity prevalence, identifying drivers, and estimating policy impacts using these two indicators.

Main Methods:

• Utilized data from the 2011 Survey of Living Standards in Guatemala.
• Employed logistic regression models to compare factors associated with household food security status.
• Assessed the potential use of both indicators for ex ante policy analysis.

Main Results:

• Significant differences were observed in estimated food insecurity prevalence between ELCSA and the household undernourishment indicator.
• Logistic regression models revealed substantial variations in the direction and magnitude of factors influencing food insecurity.
• The simulated impact of a cash transfer policy differed based on the food security indicator employed.

Conclusions:

• The choice of food security indicator critically influences the understanding and measurement of food insecurity.
• Policy design and implementation require careful consideration of indicator selection to ensure accurate assessments and effective interventions.
