Introduction
Food security—when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food—remains an unfulfilled promise for hundreds of millions worldwide. Despite producing enough food globally to feed every person, approximately 735 million people experience chronic hunger. Climate change is increasing production volatility. Conflicts disrupt food systems. Economic shocks push food beyond reach for vulnerable populations. The world faces a food security crisis that demands every available tool.
The challenge of food security spans the entire food system: production in fields and pastures, processing and storage, transportation and trade, access and affordability, and the nutritional quality of available food. At each stage, information limitations constrain decision-making. Farmers lack data to optimize production. Supply chains cannot anticipate disruptions. Early warning systems detect crises too late for effective response. Nutrition programs target imprecisely.
Artificial intelligence offers transformative potential across the food security landscape. Machine learning predicts crop yields and pest outbreaks. Computer vision assesses crop health and food quality. Natural language processing extracts insights from diverse data sources. Optimization algorithms improve supply chain efficiency. This article explores how AI is being applied to food security challenges, examining applications from farm to table and considering how to ensure these technologies serve those most in need.
