Methodology for the estimation of emissions / removals from LULUCFMethodology for the estimation of emissions / removals from LULUCF

JRC LULUCF Workshop, Ispra 13-14 November 2008

Net GHG emissions / removals (in kt CO2 eq) from the Land Use, Land Use Change and

Forestry sector by category (bars) and total (line) for the period 1990 – 2006

• The magnitude of the LULUCF sink increased by 62% from 1990 to 2006• Fluctuations in GHG removals are mainly attributed to fluctuation in areas of Forest Land burnt

by wildfires each year• Grassland category appears as a small source of CH4 and N2O due to emissions during wildfires

Combination of existing databases:

• 1st NFI (GSFNE, 1992, 1994)

• ‘Agricultural Statistics of Greece’ (NSSG, annual census)

• Afforestation registry and statistics of the Greek Ministry of Rural Development and Food

• ‘Distribution of the Country’s Area by Basic Categories of Land Use’ (NSSG, decennial survey)

Development of the National Land-Use Inventory

• Land Use Maps 1990-(2000)-2008-2012 ..with EO data

• Forest Maps from Forest Management Plans

• Afforestation registry and statistics of the Greek Ministry of Rural Development and Food

• LUC maps from local Forest Services

JRC LULUCF Workshop, Ispra 13-14 November 2008

Stock change method (GPG page 3.24 eq. 3.2.3)

- the annual change in carbon stocks in living biomass in forest land remaining forest land is estimated through

ΔC = (C t2 – C t1) / (t2 – t1)Where: Ct1 = the total carbon in biomass in time t1

Ct2 = the total carbon biomass in time t2.

C = [V ● D • BEF] ● (1 + R) ● C

V= merchantable volume, m3 ha-1

D= basic wood density, tonnes d.m. m-3 merchantable volumeBEF= biomass expansion factor for conversion of merchantable volume to aboveground tree biomass,dimensionlessCF= carbon fraction of dry matter (default = 0.5), tonnes C (tonne d.m.)-1R = root-to-shoot ratio, dimensionless

Root-to-shoot ratio (R) is also used for below ground biomass carbon.

3. Proposed Improvements

JRC LULUCF Workshop, Ispra 13-14 November 2008

Stock change method (application in Greece)

-existing information on D, BEF and R for Greek forest ecosystems is not adequate

-the European generalized allometric biomass equations will be used (Zianis, 2003; Muukkonen, 2007)

-in case, equations for some species are not available we will use relationships developed for species growing in other Mediterranean countries after validating them against existing values for Greek species

4. Proposed Improvements

JRC LULUCF Workshop, Ispra 13-14 November 2008

Case study

- the forest of Seli (Central Macedonia) has been used for the implementation of the approach

- the distributions of the DBH were derived from the management plan for each stand (123 in total) and the allometric equations were applied to them for year 1992.

For Fagus sp. and Quercus sp. the generalized equations developed by Muukkonen (2007) were used.

5. Proposed Improvements

JRC LULUCF Workshop, Ispra 13-14 November 2008

Case study (cont.)

-For Pinus nigra the equation by Fattorrini et al (2005) was used. Validation against values from other Pinus nigra forests in Greece gave a deviation of less than 6%.

-For belowground biomass the root-to-shoot ratio (R) will be derived from the literature.

-For biomass conversion to carbon, the default value of 0.5 will be used (GPG page 3.25).

6. Proposed Improvements

JRC LULUCF Workshop, Ispra 13-14 November 2008

7. Proposed Improvements

Case study (cont.)- Aboveground biomass distribution of forest stands (year 1992)

The boundaries of the forest stands were digitized and georeferenced in a GIS database.

JRC LULUCF Workshop, Ispra 13-14 November 2008

Next step

The same approach will be applied for the DBH distributions for 2002 (derived from the forest management plan) and thus the data for eq.3.2.4 (GPG page 3.24) will be available for the forest under study.

8. Proposed Improvements

JRC LULUCF Workshop, Ispra 13-14 November 2008

- For evergreen broadleaved stands, values from literature will be compiled, and after reviewing will be applied to the data derived from forest management plans.

-Forest management plans will be the basic source of information (DBH distribution and area coverage per species) for estimating C stock change in living biomass for each stand.

C STOCKS ESTIMATION IN: SOIL, LITTER, DEAD WOOD

-measurements in permanent plots (existing and new that will be selected by the end of 2008) covering the entire country
