The document discusses the four dimensions of food security: physical availability of food, economic and physical access to food, food utilization, and stability of the other three dimensions over time. Physical availability addresses the supply of food through production, stock levels, and trade. Access looks at whether households can actually obtain food given incomes, expenditures, markets, and prices. Utilization examines how well nutrients from food are absorbed and the nutritional status of individuals. Stability considers whether the other dimensions remain adequate over time or are impacted by periodic issues like weather, economics, or disasters. The document also provides recommended indicators for measuring each dimension of food security.
