1. Global scheme of the LULUCF inventory
• France applies the 2003 Guidelines for LULUCF since the submission of April 2006 for the UNFCCC. The discussions on the implementation of the reporting under the Kyoto protocol have begun in the same time.
• The inventory is based on land use change matrixes which represent all the possible land use changes.
• For each of this land the net carbon balance is estimated for each carbon pool.

13-14 November 2008 3JRC - LULUCF
1. Global scheme of the LULUCF inventory
• On forestland the carbon balance for living biomass is estimated thanks to the method of fluxes. The net balance is estimated by difference between the growth and the harvests.
Net carbon balance = carbon growth – carbon harvests
• For the dead organic matter and the soils, a tier 1 default method is used; emissions and removals are reported when there are land use changes.
∆Carbon = Carbon before conversion - Carbon after conversion
A BA=>B B=>A
Dead organic matter 1year 20years
Soil 20years 20years

2. French reporting under the Kyoto Protocol
• France chose to submit annually the estimate of the figures for the articles 3.3 and 3.4 under the Kyoto Protocol.
• France elected the only Forest management option under the article 3.4.
• The cap for France for this option is 0.88tC/year (3.2 tCO2/year) for the commitment period 2008-2012.
• A trial on the year 2006 within the Kyoto format was submitted to the UNFCCC for the 15th of April 2008.
13-14 November 2008 5JRC - LULUCF
3. Specific issue related to the Kyoto Protocol
• The reporting under the UNFCCC doesn’t perfectly correspond to what is demanded for the Kyoto Protocol especially on two points according to France:
– Areas have to be monitored from 1990 to the end of the commitment period
– The reporting must be done for smaller regions than the entire territory.
13-14 November 2008 6JRC - LULUCF
3.1. Land use change survey
• Many ways have been imagined to be able to report under the Kyoto Protocol with :
– accuracy (0.5 ha of deforested forestland must be detected),
– completeness (all the different land uses, forestlands, croplands, grasslands… must be considered)
– representativeness (the entire territory must be covered).
• France decided to use a national survey based on fixed and systematic sample plots which is named TERUTI. Since 2005, it is named TERUTI-LUCAS because of the harmonization with the other European countries within the framework of LUCAS.
• In French Guiana, this survey was not available a remote sensing based study has then been implemented.
13-14 November 2008 7JRC - LULUCF
3.1.1. TERUTI concept
•An annual area frame sampling survey
•A two-stage systematic sampling design PSUs (Primary Sample Unit) of 324 ha SSUs (Secondary Sample Unit) of 9 m2 •A double observation : for each SSU, the surveyor has to determine, on the spot, land cover and land use (2 nomenclatures).
land cover : wetland, broadleaved forest, wheat, roads …land use : agriculture, forestry, residential, leisure …
•A location based on aerial photographsfield documents used since 1962

3.1.2. Creation of matrixes to implement the inventory
• For the UNFCCC inventory different matrixes are needed for each year of inventory to separate the land keeping the same land use and the land changing of land use:
– 1 Land use change matrix for a period of 20 years
– 1 Land use change matrix for a period of 1 year
• With the Kyoto reporting another matrix is needed to separate the areas under the articles 3.3 and the 3.4:
– 1 Land use change matrix for the period between 1990 and the inventory submission.
13-14 November 2008 15JRC - LULUCF
3.1.2. Creation of matrixes to implement the inventory
• All those matrixes are very difficult to implement for two main reasons:– The 1 year matrixes are used especially to detect deforested areas
but according to the survey it is difficult to estimate if a change is temporary or permanent.
For example when a forested area is cut for wood production it is not possible to know if there will be a land use change or if the forest will come back. The choice made by France is to consider that if the area remains more than five years without forest it is counted as deforested. A special treatment has then been applied to estimate this deforestation but it means that you can estimate the deforested areas only after five years.
– There are different time series of the TERUTI database (1982-1990; 1992-2004; 2005-…)
the differences are some definitions of categories, a different number of sample plots and different places of plots. Consequently, it is not possible to have the monitoring of one plot from 1970 to today. Treatments are then needed to build the 20 year matrixes
» To make consistent the different time series of TERUTI.» To estimates all the changes during the period.
13-14 November 2008 16JRC - LULUCF
3.1.3. Case of the French Guiana
• TERUTI doesn’t cover the entire territory, and especially not the department of French Guiana which is essentially covered by rainforest. Moreover there is currently no forest inventory in this area.
• 2 specific studies have then been implemented within the framework of the Kyoto Protocol
– 1 study to estimate the area deforested
– 1 study to estimate the biomass released with this deforestation.

3.2. Reporting by regions
• In the framework of the Kyoto protocol, France has to report by smaller geographical units than the entire country. The administrative level of the regions has been chosen for this reporting which means that 26 results are reported for the LULUCF sector for the 26 different regions (with oversea territories).
– It has been an opportunity to take more specific parameters
– Many parameters and data don’t exist with this accuracy and must be estimated
– It represents a lot of work.

3.2. An opportunity for improvements• One of the base of the LULUCF inventory is the cross between the land use
data (TERUTI) and the Forest inventory data (IFN), the results of land use survey can perfectly be given by region the result for
=> France is the sum of the regional data, of course the accuracy is lower when we just look at the regional level, but it doesn’t change anything for the total.

• The IFN was able to provide data of growth and carbon stocks by super regions (5 super regions in France).
=> This changes a lot the results compared to the previous submission to the UNFCCC and should improve the relevancy of the result.
• The data for soils were also improved with updated data by region for each type of land use.
=> This changes the results too.
3.2. Estimation of unknown regional parameters
• The harvests are well known by department (smaller geographical units than regions) except for fuel wood, the national consumption of wood fuel is estimated thanks to the energy data to not forget non commercial consumption. But this data is not available by region each year. Moreover it is very difficult to estimate the transport of fuel wood between regions.
=> For the last test submission we considered that there is no transport of fuel wood between regions but inconsistencies can appear and corrections could be necessary.

4. Conclusion on the submission within the Kyoto format
• This regional reporting demands a lot of work but has been an opportunity to look for more accurate data. It is difficult to estimate the relevancy at the level of the region but French local actors feel really more concerned with this level of result.
• The monitoring of the surfaces remains a very difficult issue especially to have time and geographical consistency (especially because the Kyoto Protocol put the stress on afforested and deforested areas which are very small areas compared to the lands without change)
• No big trouble was met with the filling of the new reporting tables.

4. Conclusion on the submission within the Kyoto format
• France was very involved to estimate the balance of the article 3.3, and the first estimate for the year 2006 gave a net sink of 23.000 tons of carbon which means clearly nothing according to the level of uncertainty (impossible to know whether the future balance will be positive or negative).
• If the trends and the methodology were completely stable we could assume that the balance would be positive for the commitment period but it is currently not the case.
• It is very difficult to communicate with these different estimates under the Convention and the Kyoto Protocol, for example because the afforested areas in the Kyoto Protocol (since 1990) are not the same than in the Convention reporting (for 20 years).
• The future French submissions for the UNFCCC and the Kyoto Protocol should be completely harmonized and consistent but there is no way to check this consistency.
