Food security has four main dimensions: physical availability of food, economic and physical access to food, adequate food utilization, and stability of the other three dimensions over time. There are differences in the duration of food insecurity, including chronic, transitory, and seasonal, and in the severity, ranging from acute food insecurity to famine.

- 2. What is food? • Products derived from plants or animals that can be taken into body to yield energy and nutrients for maintenance of life and the growth and repair of tissues • Help to grow, develop & repair your body • Mixture of chemicals • Makes you happy, healthy & going • The study of food, including • How food nourishes our bodies • How food influences our health
- 3. Food choices? • Preference • Habit • Ethnic heritage • Social interactions • Availability, Convenience and Economy • Positive and negative Associations • Emotions • Value • Body weight and image
- 4. INTRODUCTION What is food security? In this presentation we will clarify and define the concept of food security. We will also examine what is unique about a food security approach to decision-making and achieving development objectives.
- 5. DEFINITION OF FOOD SECURITY How would you define food security? While food security is a multi- dimensional concept, we usually specialize in addressing one aspect of the larger food security problem. It is useful to step back from our own personal experience and examine the multi-dimensional nature of the food security concept.
- 6. DEFINITION OF FOOD SECURITY Food Security exists when all people, at all times, have physical and economic access to sufficient safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life. This definition introduces four main dimensions of food security: Physical AVAILABILITY of food Economic and physical ACCESS to food Food UTILIZATION STABILITY of the other three dimensions over time
- 7. DIMENSIONS OF FOOD SECURITY - AVAILABILITY The first World Food Conference (1974) focused on the problem of global production, trade and stocks. Hence, the original food security debate focused on adequate supply of food and ensuring stability of these supplies through food reserves. Food availability addresses the “supply side” of food security and is determined by the level of food production, stock levels and net trade. Subsequent food security efforts focused primarily on food production and storage mechanisms to offset fluctuations in global supply and ensure the ability to import food when needed.
- 8. DIMENSIONS OF FOOD SECURITY - ACCESS From the early 1980’s, the importance of food access was increasingly recognized as a key determinant of food security. Hence, food production is just one of several means that people have to acquire the food that they need. Concerns about insufficient food access have resulted in a greater policy focus on incomes and expenditure in achieving food security objectives. This has brought food security closer to the poverty reduction agenda.
- 9. DIMENSIONS OF FOOD SECURITY - UTILIZATION A third dimension – food utilization – has become increasingly prominent in food security discussions since the 1990s. Utilization is commonly understood as the way the body makes the most of various nutrients in the food. This food security dimension is determined primarily by people’s health status. Food security was traditionally perceived as consuming sufficient protein and energy (food quantity). The importance of micro-nutrients for a balanced and nutritious diet (food quality) is now well appreciated.
- 10. DIMENSIONS OF FOOD SECURITY - STABILITY The phrase “all people, at all times” is integral to the definition of food security, and is key to achieving national food security objectives. “At all times ” refers to the stability dimension of food security. It emphasizes the importance of having to reduce the risk of adverse effects on the other three dimensions: food availability, access or utilization. “All people” “All times” Different people are food secure to varying degrees and will be affected by adverse events differently. People’s food security situation may change. Adverse weather conditions, political instability, or economic factors may impact on your food security status.
- 11. For food security objectives to be realized, all four dimensions must be fulfilled simultaneously. DIMENSIONS OF FOOD SECURITY For example, even if people have money (access), if there’s no food available in the market (availability), people are at risk of food insecurity. Furthermore, food security is also about quality, and that your body must be healthy to enable the nutrients to be absorbed (utilization). These 3 dimensions should be stable over time and not be affected negatively by natural, social, economic or political factors.
- 12. DURATION AND SEVERITY OF FOOD INSECURITY DURATION SEVERITY What is the nature of food insecurity? There are important differences in how the duration and severity of food insecurity impact on people’s lives.
- 13. DURATION OF FOOD INSECURITY DURATION Inadequate food consumption may vary from a short-term experience to a life long condition. Analysts defined two general types of food insecurity: Chronic food insecurity Transitory food insecurity Chronic food insecurity is taken as long-term or persistent. Transitory food insecurity is short-term and temporary.
- 14. DURATION OF FOOD INSECURITY Chronic and transitory food insecurity have different causes: Chronic food insecurity Transitory food insecurity Is often the result of extended periods of poverty, lack of assets and inadequate access to productive or financial resources. Is relatively unpredictable and can emerge suddenly.
- 15. DURATION OF FOOD INSECURITY An intermediate type of food insecurity is seasonal food insecurity. It occurs when there is a cyclical pattern of inadequate availability and access to food. This is associated with seasonal fluctuations in the climate, cropping patterns, work opportunities (labour demand) and/or prevalence of diseases.
- 16. Availability / access to food Time Seasonality highlights times of the year when the food gap and food needs are likely to be greatest. The concept of seasonal food security falls between chronic and transitory food insecurity. It is similar to chronic food insecurity as it is usually predictable and follows a sequence of known events. However, as seasonal food insecurity is of limited duration it can also be seen as a recurrent, transitory food insecurity. DURATION OF FOOD INSECURITY
- 17. SEVERITY OF FOOD INSECURITY SEVERITY The most extreme situations, usually associated with substantial loss of life will warrant the description of famine. Food security analysts/professionals may use the term acute food insecurity to describe a severe and life threatening situation. The measure of the severity of food insecurity will influence the nature, extent and urgency of the assistance needed by affected population groups.
- 18. SUMMARY Food security exists when all people, at all times, have physical and economic access to sufficient safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life. From this definition four main dimensions of food security can be identified: • physical availability of food • economic and physical access to food • adequate food utilization • stability of the other three dimensions over time There are also important differences in the duration and severity of the way in which people experience food insecurity.
