LAND USE, LAND-USE CHANGE & FORESTRY REPORTING UNDER KYOTO

  1. 1. LAND USE, LAND-USE CHANGE & FORESTRY REPORTING UNDER KYOTO Peter Stephens Ministry for the Environment New Zealand
  2. 2. Overview of Presentation <ul><li>Obligations under the Kyoto Protocol (KP) </li></ul><ul><li>National circumstances </li></ul><ul><li>Forest carbon </li></ul><ul><li>LiDAR ( Li ght D etection a nd R anging) </li></ul><ul><li>Land use mapping </li></ul><ul><li>Improving knowledge of forest carbon </li></ul><ul><li>Reporting </li></ul>Some terms UNFCCC – United Nations Framework Convention for Climate Change KP – Kyoto Protocol IPCC - GPG – Intergovernmental Panel on Climate Change - Good Practice Guidance LULUCF – Land Use, Land-Use Change and Forestry
  3. 3. Obligations under the UNFCCC and the Kyoto Protocol <ul><li>The Kyoto Protocol (KP) to the United Nations Framework </li></ul><ul><li>Convention on Climate Change (UNFCCC) was adopted in 1997. </li></ul><ul><li>New Zealand ratified the Kyoto Protocol in December 2002. </li></ul><ul><li>New Zealand target, under KP, is to reduce greenhouse gas emissions over 2008-2012 to the level they were in 1990. (Ireland target is 13% above 1990 levels.) </li></ul><ul><li>All Parties have a legal obligation to report. </li></ul>
  4. 4. What Needs To Be Reported Under the KP Carbon stock, and stock change, for period 2008-2012 Greenhouse gas changes associated with human-induced land-use change from 1990 Five carbon pools Unbiased, transparent, complete, and uncertainties documented Reporting annually.
  5. 5. New Zealand’s National Circumstances <ul><li>Rapid changes in land use since 1840s </li></ul><ul><li>No national forest inventory (on traditional European NFI model) </li></ul><ul><li>Considerable reforestation since 1990 (~600,000 ha) </li></ul><ul><li>Officials currently unable to access all privately owned planted forests </li></ul>
  6. 6. Carbon Calculations <ul><li>At the national scale </li></ul><ul><li>Carbon Stock = emission factor by pool (t C/ha) multiplied by area of land use/land-use change for each reporting year </li></ul><ul><li>Using plots and modelling for forest and soil emission factors </li></ul><ul><li>Land use areas and land-use changes from mapping </li></ul><ul><li>Forest definition: 5m, 30%, 1ha, 30m (IRL: 5m, 20%, 0.1ha, 20m) </li></ul>
  7. 7. New Zealand Forests
  8. 8. Forest Carbon <ul><li>Permanent plots established on regular grid system </li></ul><ul><li>Measure tree diameter, height, dead wood, litter, shrubs and soil </li></ul><ul><li>Airborne scanning LiDAR used for planted forests </li></ul><ul><li>Estimates of carbon using models adjusted for diameter, height, species, management and wood density. </li></ul><ul><li>Repeat measurements underway. </li></ul>

  21. 21. Confirming land-use change (cont’d)
  22. 22. Dairy farm infrastructure
  23. 23. Method Development to Support LUCAS <ul><li>Forest Workstream </li></ul><ul><li>Establish sampling framework for all forests </li></ul><ul><li>Biomass studies of natural, planted forests, croplands and grassland with woody biomass </li></ul><ul><li>Decay studies (above and below ground) </li></ul><ul><li>Data collection manuals and processes </li></ul><ul><li>Improvement and validation of allometric equations and Forest Carbon Predictor model </li></ul>
  24. 24. LUCAS Reporting Process UNFCCC CRF Reporter CRA CRF input tables CRF output tables Data Collection & Science Calcs Results: data entry & formatting Annual report preparation Field data Carbon models Land-use mapping
