Presentation on theme: "Food Systems sets of dynamic interactions between and within the human and biogeophysical environments which result in the production, processing, distribution,"— Presentation transcript:

1 Food Systems sets of dynamic interactions between and within the human and biogeophysical environments which result in the production, processing, distribution, preparation and consumption of food. (definition based on FAO viewpoint) are based on:  3 major components, each comprising  3 key elements, each influenced by  many determinants, which determine how the FS operates

2 FOOD UTILISATION Food System Components & Key Elements FOOD ACCESS Affordability Allocation Preference Nutritional Value Social Value Food Safety FOOD AVAILABILITY Production Distribution Exchange

3 SocioeconomicBiogeophysical Advertising & media Customs, tastes & trends Food prices & household budgets Food standard regulations Labour availability & productivity Land policy & land tenure Market polices (input prices, credit & subsidies) Supply chain infrastructure Storage, processing & food preparation technologies Trade policies (border controls, international agreements) Appearance of food produced Bioavailability & bioefficacy Contamination and toxins Germplasm Natural resource base and productivity potential Nutrient content of food Plant and animal pests & diseases Primary processing Quantity & quality of food produced Seasonality of food produced Waste disposal and management Example Food System Determinants

4 Food Systems operate through connections between related determinants operating in one or more major components. fail to deliver food security when determinants, and/or the links between them, are disrupted by GEC or other stresses. can be adapted to reduce their vulnerability to GEC by:  identifying which determinants are particularly sensitive to GEC  enhancing effective determinants  restoring disrupted determinants

5 FOOD UTILISATION FOOD ACCESS FOOD AVAILABILITY HIV-AIDS Climate Change Political Unrest Floods, Droughts Currency Fluctuations Water Pollution Economic Recession War Change in Trading Agreements Range of interactive stressors on Food Systems

6 GLOBAL ENVIRONMENTAL CHANGE (GEC) Change in type, frequency & magnitude of environmental threats FOOD SYSTEM SECURITY / VULNERABILITY SOCIETAL CHANGE Change in institutions, resource accessibility, economic conditions, etc. Capacity to cope with &/or recover from GEC Exposure to GEC
