  1. Land Use Change and Other Factors Affecting Climate Change Benefits of Sugarcane Ethanol in Brazil Manoel Regis L.V. Leal Brazilian Bioethanol Science and Technology Laboratory (CTBE) Task 38 Brazilian National Team Leader Australia, November 25-26, 2013

  2. Contents • LUC/ILUC issues • Origins • Impact assessments: uncertainties • Sugarcane ethanol in Brazil • Countries emissions profile • Ways to control LUC

  3. LUC and ILUC: Why Bother? • It is required by RED, RFS2, LCFS and other legislations • They can represent significant impacts on GHG emissions, biodiversity, food security, water balance and quality, soil organic matter (SOM)

  4. What Causes LUC? • Land available for ag-expansion without deforestation (previously cleared, underutilized) = 500 to 4000 million hectares(1) This circle size reflects 1500 • Global land area impacts:[million hectares per year] • Fire = 330-430 (2) est. 380 • Dev./Urban exp. (1) = 1.5 • LUC bioenergy est. (3) = 0.2 too small to be visible (1) Enormous range due to pasture, grassland, marginal land estimates Sources: (1) Kline et al. 2009; calc. by author based on FAO 2007. (2) Giglio et al. 2010; Randerson 2013. (3) Tyner et al. 2010 (3 m ha total over 14 years = 0.2 M ha each year)

  5. Where LUC GHG Emissions Come From? LUC emissions from biofuels represent only 1% of the total! Source: Tipper, Hutchinson, Brander, 2009

  6. Some Facts • Although LUC emissions from biofuels can be significant in their LCA emissions, they represent only 1% of the global LUC emissions; • Biofuels occupied only 0.5% (27 Mha) of the managed land in 2007 (1,500 Mha arable land plus 3,400 Mha of pasture) and 2% of the arable land in the world; • ILUC GHG emissions calculations are still under hot debate.

  8. EPA – 1st round

  9. EPA – 2nd round

  10. Some Reasons For Differences • Different assumptions and data base, low disaggregation levels; • Different methodologies: co-products impacts, CGE/PE and allocation models, elasticities, yields, land price;

  11. What Needs to Be Done? • To reduce LUC/ILUC • Public policies to manage LU • Technology improvements to increase yields and reduce impacts • To improve LUC/ILUC analysis • Continue to develop better models • Produce disaggregated data for the local conditions

  12. Sugarcane Ethanol in Brazil • Country’s LU • Country’s GHG emissions inventory • PP to reduce LUC and impacts • Technology development • GHG LCA

  13. Land Use in Brazil

  15. Main Public Policies • National Plan of Climate Change (PNMC) • Low Carbon Agriculture (ABC) • Sugarcane Agroecological Zoning

  16. Deforestation Reduction Commitment

  17. Low Carbon Agriculture Loans available for implementing these technologies

  18. Degraded Pasture

  19. Dynamics of Sugarcane Expansion Source: Adami et al., 2012

  20. Agricultural and Pasture Area Outlook

  21. Pasture Area Outlook

  22. Sugarcane Agroecological Zoning 64.5 Mha of land available for sugarcane planting with low impacts. It represents only 7.5% of Brazil total area

  23. Technology Improvements to Reduce LUC • Sugarcane breeding: conventional and GM; • Low impact mechanization: reduce soil compaction and allow no-tillage planting; • Crop management: precision agriculture, increase plant density, irrigation, N fixation. Goals: increase yields and reduce fossil energy use

  24. Redução da Distância Entre Linhas Row spacing (m) Today (Brazil) Initial Target(CTBE) October2002

  25. Final Comments • LUC is a critical issue for biofuels; • The methods and data used to assess its impacts need to be highly improved; • Biofuels LUC should be considered integrated with other LUC causes; the dynamics for deforestation and other causes need to be better understood and managed; • Public Policies and technology development are important tools to reduce LUC impacts.
