Sustainable Development Goal 2 (SDG 2) aims to “end hunger, achieve food security and improved nutrition, and promote sustainable agriculture” by 2030. Despite some progress, global hunger and malnutrition remain persistent and multidimensional challenges. The COVID-19 pandemic, climate crises, geopolitical conflicts, and economic disruptions have intensified vulnerabilities in global food systems. Addressing SDG 2 requires more than policy intentions; it demands robust, cross-disciplinary research that integrates insights from health, nutrition, agriculture, environmental science, economics, data science, and public policy. This article outlines how research across domains can meaningfully contribute to each SDG 2 targets and accelerate the transition to a hunger-free world. Target 2.1: End Hunger and Ensure Year-Round Access to Nutritious Food To ensure universal access to safe and sufficient food, research must address structural inequities in food distribution and availability. Public Health & Epidemiology: Studies on food insecurity patterns, dietary deficiencies, and caloric adequacy can inform region-specific interventions. Logistics & Supply Chain Research: Academic inquiry into cold chains, food storage, and last-mile delivery systems can bridge gaps between surplus and scarcity zones. Economics & Social Sciences: Research into the socioeconomic determinants of hunger—such as income inequality, inflation, and unemployment—can guide conditional food assistance and universal public distribution schemes. Interdisciplinary research can inform adaptive food systems that are both accessible and responsive to fluctuating supply-demand dynamics. Target 2.2: End All Forms of Malnutrition Malnutrition includes both undernutrition (stunting, wasting) and overnutrition (obesity, micronutrient deficiencies). It is a biomedical and socioeconomic issue that calls for multi-sectoral collaboration. Nutrition Science: Essential […]
