Major issues facing Slovenia in LULUCF reporting and the establishment of a system for monitoring emissions and removals from

cropland and grazing land management

LULUCF Decision

Art. 3(2):For the accounting period beginning on 1 January 2021, and thereafter, Member States shall prepare and maintain annual accounts that accurately reflect all emissions and removals resulting from cropland management and grazing land management

Table NIR1 – reporting to EU

Grassland remaining Grassland: NR

Cropland remaining Cropland: partly R

Key categories in LULUCF

Completeness

• „the problem of missing information“

• Art. 5: … MS shall ensure the accuracy, completeness, consistency, comparability, and transparency of their accounts …

• completeness can refer to a reporting or data

• data completeness:

activity data

emission factors

• notation keys are used to support completeness

Completeness of activity data

• Art. 2: The approach proposed discards the parallel Kyoto Protocol reporting framework and streamlines the system with the UNFCCC "land-based" reporting framework

• When activity data are complete?

IPCC 2006: „complete, which means that all land within a country should be included (without duplication), with increases in some areas balanced by decreases in others, recognizing the bio-physical stratification of land if needed …“

• Art. 16: From 2023, their emissions and removals covered by Article 2 of Regulation in accordance with the methodologies specified in Annex IIIa …

• Annex IIIa: Spatially-explicit land-use conversion data for the identification and tracking of land-use categories and conversions between land-use categories

Completeness of activity data

Approach 3 according to 2006 IPCC guidelines!

Completeness of activity data for CM and GM

„A prerequisite for any estimating/reporting of the emissions/removals due to CM and GM, even for Tier 1 estimations, …“ (Weiss et al. 2015)

Reporting under higher Tiers for CM and GM:

• complete land use and land-use change statistics

• spatially explicit data for the activities

• the sub-division of the land into different management types (stratification) and sub-categories

General issues related to CM & GM

• Consistency in activity data for period prior to 2006

• No available data for transition period before the base year (net-net accounting!)

• No information on management regimes explored until now (potential of LPIS!)

• There is no formal soil condition monitoring at country level

• NFI does not cover biomass monitoring on CM and GM areas

• emissions from CM are assumed to be underestimated

• Liming (Saturday paper!)

• Use of country-specific data on CSC from one year of grassland growth

• A default value of ABG biomass carbon stock at harvest for cropland (63 t C ha-1)

• CRF table 4 (III) Direct N2O emissions from N mineralization / immobilization

• CRF table 4 (IV).2 Nitrogen leaching and run-off

Data collection

LPIS/ALUM system (2002- )

Improving the quality of activity data

LPIS/ALUM:- Land use- Digital vector layers- Polygons

Point sampling (1 x 1 km grid):- Land cover- Digital orthophotos- Satellite imagery (Sentinel-2)

- Consistent activity data- Update on cca. every 3 years

Land use No. of sites

Arable land 22

Meadows and

pastures24

Extensive orchards 8

Intensive orchards 6

Vineyards 10

Total 70

Improving the quality of emission factors

Around 500-600 sites are assumed to be representative to determine country-specific (reference) soil C stocks, while 30-50 permanent agricultural experimental sites to determine/verify stock change factors and to allow for possible future modelling of soil organic carbon dynamics

Plan for 2017:

• Soil sampling on cca. 100 sites

• Inventory of woody above-ground biomass (cca. 700 sampling plots)

• Questionnaire on grazing land management (LPIS areas)

Improving the quality of emission factors

• renovation of Agricultural Act

• the proposal determines the responsibility for data collection needed for improved estimation of GHG emissions and removals in agriculture

• the proposal determines which data are to be collected

Improving the national legislation
