Carbon accounting for Land Use, Land Use Change and Forestry (LULUCF)
Estimates of carbon emissions and removals involve two factors:
1. The amount of area undergoing a specific transition- this is called the Activity Data
2. The change in carbon pools association with that transition- this is called the Emissions Factor
Default LULUCF Categories in IPCC 1996 Guidelines
A. Changes in forest and other woody biomass stocks due to commercial management harvest of industrial roundwood (logs) and fuelwood establishment and operation of forest plantations planting of trees in urban, village and non-forest locations
B. Forest and grassland conversion the conversion of forests and grassland to pasture, cropland etc. can
significantly change C-stocks in vegetation and soil
C. Abandonment of cropland, pasture, plantation forests, or other managed lands
D. CO2 emissions and removals from soils
cultivation of mineral soils cultivation of organic soils liming of agricultural soils
Forest Land Forest Land Remaining Forest
Land (FF) Land Converted to Forest Land

Definitions of forest degradation
1 A long-term loss of productivity that is difficult to assess, especially when applied to soils, water, and the landscape
2 A direct human-induced loss of forest values (particularly carbon), likely to be characterized by a reduction of tree crown cover. Routine management from which crown cover will recover within the normal cycle offorest management operations is not included.
3 Changes within the forests that negatively affect the structure or function of the stand and site, and thereby lower the capacity to supply products and/or services
4 Direct human-induced activity that leads to a long-term reduction in forest carbon Stocks
5 The long-term reduction of the overall potential supply of benefits from the forest, which includes carbon, wood, biodiversity and any other product or service
6 The overuse or poor management of forests that leads to long-term reducedbiomass density (carbon stocks)
Definitions of forest degradation
Some key features of these definitions include: Canopy change Ambiguous terms Carbon stocks Other forest values Long-term effects Exclusion of deforestation Source of degradation Minimum area threshold Biomass
Definitions of forest degradation
A framework for a definition of forest degradation that meets the criteria discussed in the context of the Kyoto Protocol:
Notes: An area threshold (if required), as well as time and carbon
loss thresholds remain to be specified
A direct human-induced long-term loss (persisting for X years or more) of at least Y% of forest carbon stocks [and forest values] since time T and not qualifying as deforestation or an elected activity under Article 3.4 of the Kyoto Protocol.
Methodological options for estimating emissions from forest degradation
General methodology to estimate carbon stock changes and emissions and removals include:
Step 1: Selection of reporting method for identification of geographical location of forest degradation
Step 2: Identification of standards against which potentially degrading processes can be compared
Step 3: Identification of lands where direct human-induced forest degradation according to selected/accepted definitions has led to long-term reduction of carbon stocks >>> activity data
Step 4: Estimation of carbon stock changes and emissions and removals of non-CO2 gases due to direct human-induced forest degradation activities >>> emissions factor
IPCC Approaches and Tiers (GPG-LULUCF)
Approach 1: Areas of different land use at different times basic land use data but no tracking of land use conversions
Approach 2: A land conversion matrix by area but not spatially explicit survey of land use and land-use change
Approach 3: Spatially explicit monitoring of land use change geographically explicit land use data
IPCC approaches to determine activity data
The IPCC has set up a Carbon Accounting system of three tiers based on available data and capacity
Tier 1: “Global defaults” Default emissions factor values from the IPCC database used.
Tier 2: “Local defaults” Country defined emission factors used. Higher resolution activity data used: specific regions and land use categories
Tier 3: Uses models, inventory monitoring systems and high resolution data tailored to reflect national characteristics. Requires national and sub-national carbon inventories and repeated measurements in areas where land use is changing. Models are validated and calibrated with field measurements.
IPCC Reporting Tiers
Approaches to identification of land areas subject to forest degradation
ground-based forest carbon inventory approaches
Remote sensing techniques Combination of remote
sensing and ground-based forest carbon inventory approaches
Determination of thresholds for time and detection of minimum carbon loss, and a minimum area threshold may affect methods used for land areas identification
Definitions - forest - forest degradation
Activity data
Estimation of carbon stock changesand non-CO2 GHG emissions
Which major carbon pools to consider1. Above-ground biomass:
stems, bark, leaves, etc.
2. Below-ground biomass: roots of all sizes
3. Dead wood or dead organic matter in dead wood
4. Litter or dead organic matter in litter
5. Soil organic carbon (SOC)
Emissions factor
Estimation of carbon stock changesand non-CO2 GHG emissions
Based on of the GPG-LULUCF (Chapter 3) Methods for calculation of carbon stock changes varying
with the relevant carbon pools as well as for emissions of non-CO2 GHGs….>>identification of carbon pools
Estimation methods to determined annual decrease in carbon stocks applicable to forest degradation (regard as Forest Land Remaining Forest Land)
Estimation methods of emissions of non-CO2 GHGs caused by Human-induced activities that lead to forest degradation (regard as non-CO2 emissions from agricultural soils)
Emissions factor
Estimation methods to determine annual decrease in carbon stocks for forest degradation
Identification of carbon pools i.e. living biomass (above- and below-ground), dead organic matter (dead wood and litter) and soils
Estimating annual decrease in carbon stocks due to biomass loss Gain-loss method (Sum of annual biomass losses from commercial roundwood fellings, fuelwood gathering, and other losses) Stock change method (annual average of biomass change is the difference between the biomass at time t2 and time t1)
Estimating annual change in carbon stocks in dead organic matter Dead wood …1. Gain-loss method >> decay rate 2. Stock change method Litter……1. Gain-loss method >> transition period 2. Stock change method
Estimating annual change in carbon stocks in soils The method used for mineral soils is different from that used for organic soils
Estimation methods of emissions of non-CO2 GHGs caused by Human-induced activities
Human-induced activities considered as emission sources of non-CO2 greenhouse gases are fire, changes in water table in organic soils, and fertilization
N2O, NOx, CH4 and CO emissions from forest burning
CH4 emissions from organic soils
N2O emissions from application of mineral and organic fertilizers, organic residues and biological nitrogen fixation in managed grassland
Challenges associated with the different methods: Temporal thresholds and
spatial scales Integration of field and
satellite data Spatial impact and intensity Identification of key forest
carbon pools affected by degradation
Challenges in assessing historical forest degradation: Lack of data Insufficient capacity Temporal considerations Integration of different data
sources Inconsistencies when linking
historical and present data sets and methodologies.
Challenges and considerations
Concluding Remarks
Countries need to assess both carbon stock changes (emission factors) and the total area undergoing degradation (activity data) for their monitoring to be in line with the IPCC Good Practice Guidance
Measuring forest degradation and related forest carbon stock changes is more complicated and more costly than measuring deforestation
Focusing efforts to monitor carbon stock changes on the most important categories of carbon pools and on specific areas within the country can help both to make the monitoring more targeted and efficient and to capture the most important components with priority
The evaluation of the total area undergoing degradation is more reliably measured through combination of remote sensing and forest ground inventory
Both current and historical assessments of forest degradation will need to collect data on emission factors and activity data consistently to estimate emissions from forest degradation
