INSEA Integrated Sink Enhancement Assessment – FP 6 Michael Obersteiner DG AGRI Bruxelles 13 th Sept. 2005

FT Forest fires due to abandoned ag-land Agriculture sector second largest contributor to GHG emissions after energy sector Climate Change and oil prices require to grow more biofuels EU to upload sugar Ministers seek unity as fuel prices loom
3
Background The Kyoto Protocol requires that EU-15 reduces its GHG emissions by 8% / 1990 levels (time horizon 2008-12) Agriculture represents ~10% of EU GHG emissions –No commitment despite possible wellfare increases Agricultural and climate/env policies at a crossroad –Emission Trading Scheme (inclusion of agricultural emissions and sinks? – 23 EURO/tC) –CHP directive, Biomass Action Plan –Clean Air, Nitrate etc…directives, STS –CAP reform and cross-compliance

…the Challenge ahead…. Identification of integrative, effective and efficient Policies –Competitiveness & New Markets –Rural Development –Environmental Performance Transition planning –Mechanism design –Timing –Precise Planning and Forecasting

EPIC simulates many Processes: on a daily time step Weather: simulated or actual Hydrology: evapotranspiration, runoff, percolation, 5 PET equations,... Erosion: wind and water, 7 erosion equations Carbon sequestration: plant residue, manure, leaching, sediment,... Crop growth: NPK uptake, stresses, yields, N-fixation,... Fertilization: application, runoff, leaching, mineralisation, denitrification, volatilization, nitrification,... Tillage: mixing, harvest efficiencies,... Irrigation and furrow diking,... Drainage: depth,... Pesticide: application, movement, degradation,... Grazing: trampling, efficiency,... Manure application and transport,... Crop rotations: inter-cropping, weed competition, annual and perennial crops, trees,...

Conclusion No free lunches –transfer from Energy sector Trade-offs (Ammonia vs N2O, Minimum tillage vs. Pesticides) Heterogeneity in biophysical and economic responses. Use economic instruments or very well planned traditional (supported by precise scientific tools)
