  • Food availability:sufficient quantities of food available on a consistent basis. Food access:sufficient resources to obtain appropriate foods for a nutritious diet. Food use: appropriate use based on knowledge of basic nutrition and care, as well as adequate water and sanitation
  • Millions of people
  • Global Food Sustainability - Australia and the Road Ahead

    2. 2. Global Food Sustainability - Australia and the Road Ahead<br />Wendy Umberger, Ph.D.<br />Food Economics and Policy<br />School of Agriculture, Food and Wine<br />Mannum Community Science Forum<br />21 March, 2011<br />
    3. 3. Sustainability Defined <br />“Sustainable agriculture is integrated system of plant and animal production practices ...that will, over the long term:<br />satisfy human food and fiber needs <br />enhance environmental quality and the natural resource base upon which the agricultural economy depends <br />make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls <br />sustain the economic viability of farm operations <br />enhance the quality of life for farmers and society as a whole.”<br />Food, Agriculture, Conservation, and Trade Act of 1990 (FACTA), Public Law 101-624, Title XVI, Subtitle A, Section 1603 Government Printing Office, Washington, DC, 1990. NAL Call # KF1692.A31 1990<br />
    4. 4. The Issue: Global Food Security<br />NOT “food self-sufficiency”<br />“when all people at all times have access to sufficient, safe, and nutritious food to maintain a healthy and active life”. (World Health Organization, 1996-present)<br />3 Pillars<br />Food availability<br />Food access <br />Food utilization<br />
    5. 5. Recent Increases in World Food Prices<br />Source:<br />
    6. 6. Trends in World Hunger<br />Source: FAO <br />
    7. 7. 1 billion undernourished<br />1.3 billion overweight or obese<br />
    8. 8. Australia and Food Security<br />Australia produces about 1% of the world’s food supply<br />Contributes 3% of all food that is traded globally (2.2 % of the value in 2009) <br />5-9% of cereals (wheat, barley), meat, sugar<br />Export about 67% of all food we produce (by value)<br />#14 in terms of exports<br />If it wasn’t grown here it would need to be grown elsewhere<br />WHAT IS OUR COMPARATIVE ADVANTAGE??<br />Source:<br />
    9. 9. Economic and Political Pressures Facing Food Systems 2050<br />Global population increases<br />Changes in quantity and quality of food demanded<br />Competition for key resources<br />Climate change and climate change policy<br />Slowing of agricultural productivity growth since 1990’s<br />Future governance of global food systems<br />
    10. 10. Global Population<br /><ul><li>Currently enough food, but access is the issue
    11. 11. 6.8 billion now, 8 billion in 2030 and 9 billion by 2050
    12. 12. Increases occurring in low to middle income countries (e.g. Africa)
    13. 13. Related transformational changes- move from rural to urban & need for food, water and energy
    14. 14. Increasing pressure on constrained resources</li></li></ul><li>Demand Challenges: Quantity<br />Demand for food expected to grow by 50-80% to 2050<br />Cultivable Crop Land per capita<br /> 0.45 ha. in 1966 0.25 ha. in 1996 0.15 ha. in 2050<br />Food production has been a success due to Green Revolution, productivity growth etc.<br />Global crop yields grew by 115% from 1967 - 2007, yet the area of land in agriculture increased by only 8%<br />25% more food per capita over the past 40 years<br />
    15. 15. Land, energy, water and nutrients under growing pressure<br /><ul><li>Urbanization & income growth
    16. 16. Loss of productive land and demand for energy & water
    17. 17. Demand for protein (higher quality food) increases
    18. 18. Global energy demand projected to increase 45% from 2006 to 2030 and could double between now and 2050.
    19. 19. Biofuel debate? Food vs. Fuel...
    20. 20. Synthetic fertiliser use...
    21. 21. Global water demand increasing
    22. 22. Ag. currently consumes 70% of total global blue water withdrawals from rivers and aquifers</li></li></ul><li>How to Secure Sustainable Food Systems?<br />Reduce food wastage<br />30-40% of food is wasted<br />Requires change in behaviour (food is cheap)<br />Requires infrastructure in developing countries and rural areas (e.g. storage, transportation)<br />Education and change consumers’ values and behaviour<br />Value sustainable food production practices<br />NOT food miles<br />Coordinated food value chains and food systems<br />Consumer and retailer driven<br />
    23. 23. Sustainable Consumerism?<br />
    24. 24. How to Secure Sustainable Food Systems?<br /><ul><li>Productivity and yield increases only one piece of the puzzle
    25. 25. GMOS, input use etc.
    26. 26. Environmental footprint
    27. 27. “Food Systems” approach
    28. 28. QUALITY of food, not just more food and calories</li></ul>Already plenty of calories<br /><ul><li>Soil science, biodiversity, low & no tillage</li></li></ul><li>SAI Platform: 4 Pillars<br /><ul><li>Sustainable farming systems
    29. 29. Economic
    30. 30. Social
