  1. The FAO outlook to 2030/2050 Production, Consumption, Resources Global Perspective Studies Unit Food and Agriculture Organization of the United Nations

  2. Part 1: The outlook to 2030/2050

  3. Population growth to continue, but at a slower pace 12.0 0.09 0.08 0.07 9.0 0.06 0.05 Annual increments (billions) 6.0 Total population (billions) 0.04 0.03 3.0 0.02 0.01 0.0 0.00 1750 1800 1850 1900 1950 2000 2050 Source: UN, World Population Assessment 2006

  4. fewer OECD distortions lower stocks high energy prices weather/climate export restrictions low demand elasticities more hunger, uncertainty R&D, GR low energy prices high government stocks OECD support, export subsidies

  5. World Bank lending for irrigation and drainage 1960-2005:

  6. How much more food needs to be produced?

  7. How would high energy prices change the outlook?

  8. Energy market (TPES): nearly 500 EJ Biomass: 50 EJ (80% in developing countries) Biofuels: 2.1 EJ, on ca. 26 million ha Transport energy needs: ca. 95 EJ Crop area to cover transport energy needs: >1000 million ha, i.e. 2/3 of global crop area. Energy market is large, creates perfectly elastic demand for agricultural produce at break-even points (parity prices). How big is the energy market?

  10. Will a shift to 2nd generation biofuels bring alleviation/solution?

  11. Energy market is big relative to the food market Food – fuel competition is competition for resources (land, water) (not between food and feed feedstocks!) More efficient feedstocks would help reduce area at limited demand, but at potentially unlimited demand, demand for feedstocks will rise (potentially in a big way). More R&D in more efficient biofuel feedstocks may have unexpected and even unintended area expansion effects: Beware of what you are wishing for/investing in! More R&D in more efficient feedstocks?

  12. Is there enough land?

  13. How much land is in use, how much is available now and in 2050? 1200 1066 1031 1000 874 Suitable for rainfed crop production 800 Arable land use, 2005 million ha Arable land use, 2050 600 497 366 400 387 220 265 200 237 236 99 212 203 86 0 Latin America sub-Saharan East Asia South Asia Near Industrialized Transition and Africa East/North countries Economies Caribbean Africa Source: Global Perspective Studies Unit, FAO

  14. Arable land expansion Land with (rainfed) crop production potential (million ha) Source: AEZ 2002

  15. Is there enough suitable irrigation land?

  16. Table 7 Total arable land: data and projections Irrigated land expansion and water use Area equipped for irrigation

  17. Is there enough water?

  18. 287 mha, 219 mha irrigated in developing countries 70% of all freshwater use 20% of cultivated land in DCs 40% of agricultural production in DCs 60% of cereal production in DCs How important is water for agriculture and food security?

  19. Is there enough water? Irrigation water withdrawal as a share of renewable water resources (%) 70 Today in 2030 60 50 40 30 20 10 0 East Asia South Asia Latin America All developing countries sub-Saharan Africa Near East/North Africa Source: Global Perspective Studies Unit, FAO

  20. still significant water use efficiency gains to be had Irrigation efficiency by region (in %) 100 90 Today in 2030 80 70 60 50 40 30 20 10 0 All developing East Asia South Asia s-Saharan Africa Latin America Near East/North Africa

  21. Is there enough yield potential?

  23. Yield increases and yield gaps Wheat yields: 16 countries with over 4 million tonnes of mainly rainfed wheat production

  24. Iowa maize yield 61-90; 90-08 12 9 b=206 kg/ha/yr 6 Maize yield (t/ha) 2 R =0.61*** b=95 kg/ha/yr 3 2 R =0.51*** 0 1960 1970 1980 1990 2000 2010 Year

  25. Climate change: the role of agriculture

  26. Climate change: the impact on agriculture

  27. ∆Yield biophysical changes: • highertemperatures and more evaporation • more precipitation and higher rainfall variability • more frequent extreme weather events  higher production variability • inundation of coastal areas • melting glaciers, water circulation, irrigation potentials • higher atmospheric CO2 concentration impacts on agriculture/food • high latitude areas: ↑yields for GMT <2.5°C, ↓yields >2.5°C GMT • low latitude areas: ↓yields even for ↑temp 1-2°C • globally production neural up to +2C GMT, but lower production in low-latitude areas • Higher yield variability due to weather extremes • high latitudes: more land suitable for agricultural production (+160 million ha), low latitudes: less land for agricultural production (-110 million ha) • CO2 fertilization effect, but uncertain • fire risks, pests and diseases, food safety, e-coli, malaria, etc.

  28. Summary and conclusions • Future output challenges • +70% more food production to 2050, but slow down in growth • overall enough resources (land, water, genetics), but growing regional/local resource pressures (land, water) • energy market huge, energy demand cannot be met by agriculture • climate change to increase pressure on the resource base of the poor • more productive agriculture needed to fight hunger, poverty • R&D needs to meet the challenges • Invest more specifically to address the needs of the poor (abiotic stress, crops of the poor) • Divergent R&D needs in developed and developing countries: rebalance productivity growth with other goals such as nutrition, environment, etc. • CC: R&D to promote productivity growth, to minimize acreage expansion • CC: R&D for abiotic stresses (drought tolerance, etc.) • but prioritize mitigation over adaptation (timing, financing); seek win-win (CA/NT) • Bioenergy: R&D investment in more efficient biofuel feedstocks? Unintended area expansion effects possible! • Timing, sequencing: Invest steadily, avoid pro-cyclical action and price movements; synchronize R&D investment with other measures (water pricing, water use efficiency); take into account the long gestation periods. • Organize/co-ordinate R&D: Combine expertise of the private sector with needs and constraints in developing countries: PPPs, humanitarian use licenses, etc
