During the last years, a demand for regionally produced biogas feedstocks was created by government subsidies to biogas production in Germany—contrary to the trend of specialization of agricultural production towards global commodity markets. The question arose whether this trend could contribute to an increased cultivation of uncommon crops and diversification of cropping patterns, owing to comparably different and less restricted feedstock requirements. In the cooperative research project "EVA," a multi-site experimental crop rotation field trial was conducted over 8 years at eight sites, representing the variety of soil-climatic conditions in Germany. The aim of the trial was to assess a variety of established and novel crops for anaerobic digestion. This paper presents the key findings of the trial. Special emphasis is given to biomass productivity and profitability. The chances for the approach "diversification of cropping patterns via energy cropping" are discussed. Results show that maize (average 4-year dry matter yield varied site-specific between 14.22 and 25.12 t ha−1) is clearly the most efficient crop for biogas production in Central Europe. Some cropping options for biogas feedstock production, such as winter triticale (whole crop, average yield of 6.71 to 15.17 t ha−1) or perennial fodder mixtures (average yield of 7.51 to 19.44 t ha−1) are feasible choices for farmers in some regions, which could contribute to diverse cropping systems.

With the institutional setting for the Banking Union having been established and become fully operational, market participants, supervisory staff, and academics are gradually getting to terms with the reality of the new two-tier system of supervisory and resolution authorities within the Eurozone. Drawing from media coverage, input from practitioners and the on-going academic debate, the present article seeks to present an-inevitably provisional-assessment of the new regime from a German perspective. While regulatees and their advisers within the country appear to have got used to the new reality, the paper also identifies a number of residual concerns, some of which are attributable to the specific characteristics of the German financial sector, others indicative of broader problems.

Purpose: The European 'Healthy Lifestyle in Europe by Nutrition in Adolescence' (HELENA) project evaluated two different approaches to harmonize the matching procedures between 24-h recall data and food composition databases. In the first approach, the 24-h recall data were linked to the local/national food composition databases using standardized procedures, while in the second approach, the 24-h recall data were linked to the German BLS database which includes a larger food list. The aim of this paper was to compare the intakes of energy and eight nutrient components calculated via both approaches. Methods: Two non-consecutive 24-h recalls were performed in 1268 adolescents. Energy, carbohydrates, proteins, fat, fiber, water, alcohol, calcium and vitamin C were calculated via the two approaches at individual level. Paired samples t test and Pearson's correlations were used to compare the mean intakes of energy and the eight mentioned nutrients and to investigate the possible associations between the two approaches. Results: Small but significant differences were found between the intakes of energy and the eight food components when comparing both approaches. Very strong and strong correlations (0.70-0.95) were found between both methods for all nutrients. Conclusion: The dietary intakes obtained via the two different linking procedures are highly correlated for energy and the eight nutrients under study. [ABSTRACT FROM AUTHOR]
