  1. Projecting GHG emissions & removals from Agriculture & LULUCF New Zealand methods & experiences Leonard Brown New Zealand Climate Change Office Presented at the UNFCCC workshop on projections Bonn Sept 6-8 2004

  2. Institutional arrangements(for inventory & projections) New Zealand Climate Change Office Projections LULUCF Projections MAF Agriculture Projections Ministry of Agriculture and Forestry MAF National exotic forest database Statistics New Zealand Animal census & survey Forest Research Ltd Growth & C sequestration model AgResearch Ltd CH4 Tier 2 methodology Overseer N20 model NZCCO NZ Carbon Accounting System

  3. Carrying capacity Weather $NZ Prices Livestock data Agriculture Animal population by species: beef, sheep, dairy, deer – (Pastoral Supply Response Model) Productivity & emissions per animal. Forecast of nitrogen fertiliser usage. • Policies & Measures • Environmental N constraints • Price measures (C) • Research

  4. Agriculture improvements General model development - equations Changes in input parameters over time, e.g. forage quality Sensitivity analysis and scenario building Improved estimation of carrying capacity limit Improved stock unit estimation by livestock class

  5. 10000 ha 10% deforestation 30000 ha 0% deforestation 20000 ha 5% deforestation planting and Kyoto deforestation scenarios Forestry Key drivers • Area planted in Kyoto forests to date • Scenarios of future new forest planting • Carbon accumulation models • Assumed rotation length • Deforestation

  6. Forestry improvements • Modelling - Capability and Flexibility Improve modelling – scenarios, vary multiple parameters • Data - New Zealand Carbon Accounting System Refine & validate the accuracy of plantings since 1990 Refine and spatialise growth rates of planted forest Improve deforestation estimate Improve estimate of carbon in all pools for all forest
