Potentieller Beitrag der Landwirtschaft zur Verminderung der Treibhausgasemissionen in Deutschland AgEcon
Wegener, Jens Karl; Lucke, Wolfgang; Heinzemann, Jorg.
In 2002, the German agricultural sector contributed 8.7 % of the total national green house gas emissions. The main sources were animal digestion, manure management and agricultural soils. From the technical point of view, the manure management has the biggest potential of green house gas reduction by using biogas technology. Thereby methane emission from manure, which otherwise had been emitted into the atmosphere, can be recaptured and used to substitute fossil fuels. Regarding the whole output of manure from cattle and swine in Germany, the emission reduction is 56 Mio. t CO2-equivalent. This amount is equivalent to 4.5% of the emissions in 1990/95 for the Kyoto protocol. Regarding the biomass potential which is technically feasible at the moment, the...

Influence of production methods and transport distances on the Greenhouse Gas-Balance of organic apple juice AgEcon
Engel, Anna-Maria; Wegener, Jens Karl; Lange, Marco.
Organic farming is the most adequate system for the production of food and other agricultural 9 products to sustain ecological and environmental sources. Ecologically produced foods are 10 becoming more and more popular; accordingly, the demand for organic products is growing. In 11 addition to the renunciation of the use of chemical fertilisers and pesticides, the philosophy of 12 this type of food production includes as well the benefits of seasonal and regional goods such 13 as short ways of production and distribution. 14 In the present study the total emissions of greenhouse gases (GHG) in the production of 15 organic apple juice from two different regions were investigated. The goal of the analysis is to 16 clarify whether extensive agricultural...
