Content 1. Defining the given task 2. Methodological and database aspects (examples) Machinery Diesel fuel Drying Buildings 3. Results 4. Outlook and discussion 3
Defining the given task Objectives - Improving the environmental pressure indicators - Quantifying energy requirements of agricultural production in detail Work description - Setting up process-related parameters on energy requirements - Considering major prevailing production and housing systems - Displaying regional differences - Developing a projection module 4
Energy requirements of agricultural production Covers (beside others): machinery buildings concentrates fertilizer fuels pesticides 5
Energy Resources System Border Direct Input Fuels, Lubricants Combustibles Electricity Indirect Input Buildings Machinery, Facilities Seed, Pesticides Mineral Fertiliser Basic Ration, Concentrates Young Animals, Straw CAPRI Production Activities Plant Production: Cultivation Fertilizing Application of organic manure Seeding Chemical Plant Protection Mechanical Plant Protection Harvesting Transportation Animal Production: Feeding Milking Manure Management Transportation Product Treatment Arable Crops Drying Cleaning, Sorting Fodder Production Conservation Drying Storage Animal Production Milk Cooling Agricultural Sector Products Arable Crops Soft Wheat Barley Rape Potatoes etc. Fodder Production Grass Grass Silage Hay Animal Production Milk Young Animals Beef Side-Products Straw, Org. Manure 6
Energy requirements: assessment coefficients - Consideration of the consumption of all non-renewable energy resources - System border: all along the production chain of direct / indirect inputs - Uniform methodological approach - Database: Agroscope ART / Ecoinvent, SALCA061 database 1 kg Diesel 7
Machinery and diesel fuel Methodology for machinery energy: - Assessing all tractors and harvesters in all NUTS-II (EUROSTAT, national sources) - Consideration of energy requirements during useful life of machinery (KTBL, Ecoinvent, ART) - Adding trailed machinery - Consideration of grassland use and yields - Including energy required for machinery shed Methodology for diesel-fuel requirements: - Consideration of soil quality, plot size, no-till percentage - Grassland use and yields - National consumption levels 8
Energy assessment Energy requirement by machinery depreciation Unit: MJ/ha Activity-based machinery weight: Allocation by: Crop statistics, operating time Lifetime distribution Weight assessment All tractors (NUTSII) Source: Fendt 9

Champagne-Ardenne: Soft wheat machinery energy diesel energy Champagne- Ardenne Machinery Energy (MJ/ha) 1241 Diesel fuel 5033 11
Cereal grain drying Problem : - Relevent energy requirements depending on moisture content at harvest but: statistical data available only for a few regions Methodology: development of an estimation model based on: - Statistical data on moisture at harvest if available - Climate data from CRU University of East Anglia (long-term and annual data 2000-2002) - Crop data from JRC (to exclude non-relevant observation points) Setting up the model: - Principal Component Analysis (5 activities) - Linear estimation model using 5 PCs Source: Dryiar.com 12
Mecklenburg-Vorpommern: Rye drying Drying energy energy Mecklenburg- Vorpommern Drying requirements Share of drying energy Energy (MJ/ha) 1840 15081 12.2% 13
Buildings` energy requirements Problem: lack of statistical data on number, age and structure of buildings...therefore: - Use of UN-Data - Dividing EU into Iso-Buildings-Regions - North / Middle / South - Use of herd size distributions from EUROSTAT 14
Energy assessment Energy requirement for building depreciation and maintenance; Unit: MJ/head Herd Size distribution Building type Using UN-Data Animal activity per Region 15
