Validity and reliability of food security measures

Area of Science:

• Agricultural Economics
• Development Studies
• Public Health

Background:

• Existing food security indicators vary in validity and reliability.
• Practical application of these indicators, especially in international frameworks, requires careful consideration of their limitations.
• The post-2015 Development Agenda necessitates robust monitoring tools for food security goals.

Purpose of the Study:

• To review current food security indicators and assess their conceptual validity and measurement reliability.
• To raise awareness of the inherent trade-offs among different food security measurement tools.
• To inform the development of a practical international monitoring framework for food security.

Main Methods:

• Literature review of existing food security indicators.
• Conceptual analysis of indicator validity and reliability.
• Discussion of practical considerations for international monitoring.

Main Results:

• No single food security indicator is universally valid or reliable under all feasible conditions.
• Significant trade-offs exist between indicator accuracy, cost, and ease of implementation.
• Current indicators may not fully capture the multifaceted nature of food security.

Conclusions:

• Careful selection of food security indicators is essential, considering specific contexts and monitoring objectives.
• Awareness of measurement limitations is critical for accurate global food security assessment.
• The study contributes to defining effective food security goals and monitoring frameworks for sustainable development.
