Addressing food and nutrition security in developing countries depends on livelihood security, vulnerability, and coping strategies. Food security exists when all people have reliable access to sufficient nutritious food. Key elements of food security assessments include livelihoods, vulnerability to risks and shocks, and coping strategies. The three pillars of food security are availability of food, access to food, and utilization of food. Malnutrition is a global problem impacting health, growth, and development. An integrated approach blending traditional and modern agricultural and nutrition practices can help support food and nutrition security.
