Professor Timothy Reeves FTSE, international and national consultant on Sustainable Agricultural Intensification and Food Security, presented at the UNAA Victoria Global Food Security & Sustainable Agriculture Seminar held on Tuesday 29 October in Melbourne.

Held in support of the United Nations Zero Hunger Challenge, in partnership with NAB and the University of Melbourne, this seminar was part of the UNAA Sustainability Leadership Series and sought to build momentum for collective action on food security and sustainable agriculture post Rio +20.

Bringing together experts and practitioners from government, business, civil society, farmers' organisations, research and academia, the seminar sought to provide a platform for shared learning and discussion on Australia's role in addressing the global food security challenge and advancing sustainable agricultural practices.

It highlighted the challenges and opportunities that Australian government, businesses, and NGOs face as they contribute to developing and promoting sustainable food supply chains that increase food production, preserve natural resources and fight hunger at the local, national and global level.

UNAA Global Food Security & Sustainable Agriculture Seminar - Professor Timothy Reeves FTSE

  1. 1. Food Security • Global  • National • Local  ‐ Quantity ‐ Quantity, Availability, Use ‐ Quantity, Availability, Use,  Access • Household ‐ Quantity, Availability, Use,  Access, Nutrition
  2. 2. FOOD SECURITY EQUALS ACCESS TO  FOOD, ITS AVAILABILITY, THE WAY IT IS  UTILIZED AND ITS COMPOSITION From Sir Gordon Conway’s book – ‘One billion hungry: can we feed the world?’
  3. 3. FOOD SECURITY
  4. 4. ‘DOUBLE’ FOOD  PRODUCTION BY 2050
  5. 5. Population density 2000 http://www.pbs.org/wgbh/nova/worldbalance/eart-01.html
  6. 6. Why? Food Demand By 2050 dietary shifts will result in the consumption equivalent of about 11.5 billion people at 2009 diet levels. POPULATION = 9 BILLION Source: United Nations Estimates
  7. 7. Energy • 1400 litres oil equivalent/year to feed one person (developed world) • Nitrogen fertilizer – utilizing ‘fossil fuel’
  8. 8. Why? Urea production requires fossil fuels. equivalent of four barrels of oil to produce one ton of urea. 4-barrel energy equivalency equivalent Urea = 46% Nitrogen
  9. 9. Food Waste • FAO – 30%+! • Storage, handling, transport • Sustainable diets
  10. 10. Food crisis – declining stocks Source: J. Dixon 2008 CIMMYT® www.cimmyt.org
  11. 11. Climate change • Warmer, drier • More variability • More extreme events • Elevated CO2 http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=48751
  12. 12. Energy farming • Biofuels –Ethanol –Biodiesels
  13. 13. Food security – What’s needed? • Increased yields • Increased productivity • PROFITABLE
  14. 14. More with less – Sustainable Production  Intensification (SPI) ‘Save and Grow’
  15. 15. ‘Save and Grow’ Helping Farmers Implement Sustainable Production Intensification The views expressed are those of the author and not necessarily of the institutions identified.
  16. 16. Scale? Smallholder and broadacre farmers Scale neutral!
  17. 17. Technical principles • Agricultural productivity             Natural capital and ecosystems services Simultaneously! • Enhanced input‐use efficiency  • Use of biodiversity – natural and managed – to build farming system resilience  
  18. 18. How? • Minimize soil  disturbance  by minimizing tillage • Enhance and maintain  soil organic cover • Cultivate a wider range  of plant species
  19. 19. • Better varieties • Enhanced crop  nutrition based  on healthy soils • Integrated  management  of pests, diseases and weeds • Efficient water management
