Presentation Transcript

  1. Giuliana Zanchi and Marcus Lindner Carbon budget of European Forests: an inventory based method Sissi-Lassithi, Crete, 14th Nov 2006

  2. Outline • Methods • Carbon stock • Carbon stock change • Next steps

  3. EFISCEN model Forest C-budget inventory based approach Yasso model CarboInvent

  4. Input from other models Forest types Growth changes due to environm. change Forest managem. Wood demand Afforest./ Deforest. Volume scenario Age • Projections of: • Stem/wood volume • Net annual increment • Age class distribution • Removals • Forest area • Natural mortality Felling residues Soil module: C stocks and heterotrophic respiration Whole tree carbon stocks Litterfall EFISCEN Data from national forest inventories matrix Matrix generator EFISCEN matrix simulator

  6. CarboInvent Carbo Europe IP Extended to all Europe Applied to 6 countries

  7. C stock (2000) EU13+2 (N, CH)

  8. C stock (2000) • On average: • 55 % in the soil • 35% in the aboveground biomass • 10 % in the belowground biomass  Age distribution, species, etc.

  9. -1.00 – 0.00 0.01 – 2.00 2.01 – 3.00 3.01 – 4.00 4.01 – 4.50 C stock change (1995-2010)

  10. Assumptions: • Forest area: • Available for wood supply • Constant (no ARD) • FM: according to country indications • Wood demand ( fellings) based on: • Roundwood production statistics of FAO • from 2006 slow increase in demand (OECD projections)

  11. C stock change (1995-2010) • 8.3 % increase of C stock • 11.7% in biomass • 5.6% in the soil

  12. Large range of variability (regions): +31% to -6% of C stock change (1995-2010)

  13. LIMITS • Biomass: • Inventory data: updates • Biomass factors, turnover rates, ... • Forest area = available for wood supply, no changes • Low resolution (Med. Countries) • Soil: • Input data (litter quantity/quality, climate): NO soil type • Validated for Nordic countries • ...

  14. Next steps • Develop estimates for EU25 • Evaluation of parameters to be applied in new countries • Increase resolution (?) • COMPARISON with other estimates

  15. Thank you for the attention!
