JRC-AL: WORKSHOP, DATE …. Soil Map again Relative decrease of organic carbon stocks Relative decrease of N2O fluxes

JRC-AL: WORKSHOP, DATE Potential vs. actual simulated yield

JRC-AL: WORKSHOP, DATE → The model calculates full balance of nitrogen, carbon and water → Spatial resolution: from 1 km-pixel to continental → matching of environmen- tal conditions with anthropogenic activities → Temporal resolution of the model is <= 1 h for some processes

JRC-AL: WORKSHOP, DATE Short-term improvements → Realistic weather from 1975 – 2005 → Slightly improved fertilizer and manure distribution → Estimation of potential yield → Higher number of HSMU → DNDC on windows and unix computers → Distributed simulation

JRC-AL: WORKSHOP, DATE Improved version of the HSMU layer HMU (Homogeneous Mapping Units): Individual ID for the intersection of -Slope - Administrative borders - Soil mapping units - Soil typological units NCU: Aggregation of the STU  Result will be an update of the old HSMU layer with Corine resolved (as discussed in Paestum) HSMU: (Homogeneous Soil Modelling Units)  Dissolve SMU layer  HSMU-II will not be georeferenced … but ‘pure’ from viewpoint of environmental characteristics NITRO-EUROPECCAT

JRC-AL: WORKSHOP, DATE 1. High resolution forest mask

JRC-AL: WORKSHOP, DATE Re-sampling to 1 km scale (majority)

JRC-AL: WORKSHOP, DATE 2. Corine will NOT be used any more to delineate the HSMU -Reduction of the number of the HSMU (relevant for the generation of the agri-land use map) -Corine 100 m will be used to calculate “land cover shares” in HSMUs

JRC-AL: WORKSHOP, DATE 3. Working at the STU-level -without Corine and with STU there are HSMU for EU25 -transparent application of pedo-transfer rules ….

JRC-AL: WORKSHOP, DATE Simulating cross-compliance → Set up default run on the basis of CC measures and compliance assumptions → Review of the parameterization of important management activities Tillage Irrigation Fertilizer application → Two Tier-approach Simple implementation fo CC measures to screen a wide range of measures More detailed evaluation of most sensitive measures

JRC-AL: WORKSHOP, DATE Simulating cross-compliance(cont’d) → More attention to crop-specific data (genetic variability, regional differences) → Continue to work on nitrogen application rates → Focus of simulations: NEU: EU-GHG balance of arable soils CCAT: specific crops/scenarios
