  • 1. EX-ACT: EX-Ante Carbon balance Tool Madeleine Jönsson, FAO Carbon in Soils, Kulturhuset, Stockholm 08.05.2012
  • 2. Outline of this Presentation Outline of the presentation• What is EX-ACT• What can EX-ACT do• Why the EX-ACT tool• The EX-ACT tool: technical description - The structure and logic of EX-ACT - One example from case studies
  • 3. WHAT IS EX-ACT ? What is EX-ACT?• EX-ACT : – A tool to conduct the carbon balance appraisals of Agricultural, Forestry and other Land Use (AFOLU) projects• Developed by: – FAO Economic Division (ESA), FAO Investment Center (TCI) and Policy Support Services (TCSP)• In collaboration with: – French Development Research Institute(IRD), GIZ, IFAD, AFD(France) AfDB, SEI(Sweden), ADEME (France), World Bank
  • 4. What can EX-ACT do?• Assess the carbon balance of – AFOLU projects – Value Chains – National Strategic plans/policies• Select activities with better potential to cope with sustainability• Help decision making during project formulation
  • 5. What can EX-ACT do? Takes into account activities Deforestation, A-Re/forestation, forest degradation, Restoration of grasslands, livestock, cultivation of annualcrops, cultivation of perennial crops, fertilization of crops, installation of building, installation of irrigation systems... that impact GHG fluxes (emissions and sinks) CO2, CH4, N2O from and to different pools above-ground biomass, below-ground biomass, soil, litter and dead wood EMISSIONS  STOCKS  Carbon balance in t of eq-CO2 Positive result : There are more emissions  Negative result: There are less emissions  MITIGATION !
  • 6. Why the EX-ACT tool? Advantages Limitations• Well suited for the assessment of Lacks a link to yield/agricultural projects activities on various land- productivity indicators use areas and scale• Flexible• Projections for longer time horizons• Simple, user-friendly, cost effective• Interactive and participatory• Output can be used for financial and economic analysis• It is Excel based
  • 7. Why the EX-ACT tool? • Project formulation • Developing future Project and strategies and policy design objectives • National/regional level agricultural ProgrammeEX-ACT Value chain • Cost-effectiveness analysis (MACC) Economics • Analysis of the and finance possibility to access public funding or the carbon market
  • 8. EX-ACT: technical description
  • 9. The The structure and logic of EX-ACT structure and the logic of EX-ACT EXCEL File Project activities Project Carbon balanceDescription (identification of expected land use and practices changes) Continent Deforestation Afforestation and Reforestation Forest degradation Climate Non forest land use change Annual crops Perennial crops Matrix Soil Irrigated rice (Synthesis of land Grasslands use and land Exploitation of organic soils Duration Livestock use changes) Inputs Other investments -Describe Tier 1: -Start situation vegetation/animals/inputs IPCC coefficients concerned -Future without project -Describe main management -Future with project Tier 2 : ad-hoc practices -Area concerned
  • 10. The structure and the logic of EX-ACT The structure and logic of EX-ACT 3 different dynamics of change Difference used to compute the final C(ha of land use, number of cattle heads,…) (adoption) of practices balance in tons CO2 equivalent x2 With project Variable considered Benefits of the project x1 Without project x0 Implementation phase Capitalization phase Time (years)
  • 11. The structure and the logic of EX-ACT The structure and logic of EX-ACT 3 different dynamics of change (adoption) of practiceAbsolute Change “Immediate” “Linear” “Exponential” (x1-x0) Time t0 t1 t0 t1 t0 t1 (years) Default option in Tier 1
  • 12. The structure and logic of EX-ACT: results2 types of results: • Gross results • Carbon balance (net benefits of the project)
  • 13. The structure and logic of EX-ACT: gross results• Emissions: 100 000 t 30 000 t• Sequestration: 20 000 t 50 000 t
  • 14. The structure and logic of EX-ACT: gross results 120 100 100 80 80 60 t CO2-eq 40 with 20 0 30 Emissions + -20 Sequestration = TOTAL without -20 -20 -40 -50 -60
  • 15. The structure and logic of EX-ACT: C balance 100 80 80 60 40 20t CO2-eq 0 -20 with without C balance -20 -40 -60 -80 -100 -100 -120
  • 16. Example: carbon balance appraisal of a projectThe East African Dairy Development (EADD) Project in collaboration with the Mitigationof Climate Change in Agriculture (MICCA), FAOObjective: Increase agricultural livestock productivity with an increased focus on agro-forestryTargets: 7.500 farm familiesMeans: improved feeding practices, increased agro-forestry, stop residue burning, adoption of improvedpractisesDuration of carbon balance appraisal: 3+17 years 600000 Gross fluxes EADD Project 400000 Gross fluxes scenario 1 200000 Gross fluxes scenario 2 0 -200000 -400000 -600000
