SummaryWhen considering low-intensity farming systems in Europe, one would not normally think of Germany because the farmland in most of its regions is characterized by intensive agriculture. However, there is currently great concern about the situation of extensively used meadows and pastures in mountainous areas. Among the most attractive regions are the common grazings in the southern part of the Black Forest and limestone grassland grazed by sheep on the Swabian Jura. Both regions are located in the Federal State of Baden-Wuerttemberg. Details of the current agricultural situation, developments to be expected in the years to come, policy measures needed to preserve the cultural and ecological richness of the regions, and options for land-use-systems are discussed in relation to one another, for Less Favoured Areas (LFAs) in the Federal State of Baden-Wuerttemberg.

The multiple land use of agricultural areas is a building block for increased land use efficiency. Unlike monoculture, integrated crop–livestock systems optimally improve ecosystem services, making it an important field of research and application for adapting land use and food systems that have sustainability deficits. The integration of sheep in viticulture production is described as a promising example of an integrated crop–livestock system. While some studies of the integration of sheep into vineyards are already available for other parts of the world, there is still no research on its implementation in Central European viticulture systems. In order to fill this gap of knowledge, we conducted standardized interviews with 34 winegrowers who already graze sheep in their vineyards. The method allowed a wider overview of the implementation of the integrated crop-livestock system than would have been possible with other approaches. Furthermore, the authors kept sheep in their own vineyard for three years to evaluate the statements of the survey participants. The period during which sheep graze in vineyards is quite heterogeneous in Central Europe. Some farms use sheep only during vine dormancy; others also let sheep graze during a certain period in summer. There are also viticulture training systems where grazing is almost continuously possible. In Central Europe, summer grazing normally requires operational adjustments such as lifting the wires of the training system and branches of the vine; otherwise, the vines could be damaged. This option seems to be tailored to the training system in use. Some interviewees mentioned that sheep not only use the accompanying vegetation as fodder and therefore control the undervine growth, but in some cases, they were also able to replace other work processes, such as defoliating the grape zone or cleaning undesired vine shoots near the ground. However, a high additional workload due to livestock keeping was also mentioned by some survey participants. Some of the interviewees cooperate with shepherds, which could help to solve this challenge. Finally, we summarize possible opportunities and risks of this integrated crop–livestock system. Integrating sheep in vineyards seems to be quite feasible in the period of vine dormancy, whereas more information and considerably more effort is needed to integrate sheep during the vegetation period. Further research is needed to answer open questions especially for the necessary adaptions of the common vine training system or the implementation of alternative systems more suitable to combine with livestock keeping. Some practitioners found opportunities to merchandize the use of sheep in wine sales. This potentially unique selling point could be a solution for a broader consideration of sheep in vineyards.

Background: Danshen (Radix et rhizoma Salviae miltiorrhizae; Salvia miltiorrhiza Bunge, Lamiaceae) is commonly used in Asia, including China, Japan, and Korea with markets in America and Europe growing substantially. It is included in multiple pharmacopeias and salvianolic acid B and tanshinone IIA are used as quality markers. However, on the markets, substitutes and different processing methods often are a concern. a concern regarding patients’ safety and expected outcomes.Aims: This study aims at understanding the quality of Danshen-derived products on the market, and the relationship between the chemistry, biological activity and the processing and storage methods.Methods: For heavy metal analysis, inductively coupled plasma optical emission spectrometry was used. High performance thin-layer chromatography and proton nuclear magnetic resonance coupled with principal component analysis were used to understand the variation of metabolite composition. MTT assay and LPS induced NO production assay were used to evaluate the cytotoxicity effect and anti-inflammatory activity, respectively.Result and Discussion: Six out of sixty samples exceed the limits of cadmium according to the Chinese or United States Pharmacopoeia. Arsenic, lead and copper contents are all below pharmacopoeial thresholds. With more complex processing procedure, the risk of heavy metal contamination increases, especially with arsenic and cadmium. The metabolite compositions show a variability linked to processing and storage methods. Authenticated samples and Vietnamese primary samples contain higher salvianolic acid B, and their chemical compositions are more consistent compared to Chinese online store samples. Overall, a significant chemical variation can be observed in Danshen products directly linked to processing and storage method. In the MTT assay, fourteen samples show cytotoxicity while seven samples increase the proliferation of RAW264.7. In the LPS induced NO production of RAW 264.7, only seven samples show significant inhibitory effects.Conclusion: This is the first interdisciplinary investigation focusing on understanding the current market and the quality of Danshen. The quality of Danshen products on the high street are inferior to the authenticated samples. The results of the bioassays selected is not useful to differentiate the quality and composition according to the current definition in the pharmacopoeias. Overall, this approach highlights the tremendous variability of the products linked to processing and the need for more systematic and stringent quality assurance.

Germany is the largest milk producer of the 28 EU Member States (statistically still including Great Britain) and dairying is the most important single sector in German agriculture. Dairies are of central importance in the value chain, but very little is known about their objectives and perspectives in relation to grassland management, feedstuffs deriving from grassland and towards resource conservation issues. This study gives an insight on the way German dairies think about and act in such topics by using a standardized survey method. The survey revealed little to no linkage between the size of dairies and their interest in conservation issues on grassland and very little consideration of extensive grasslands. Dairies are divided over questions of governance for a more sustainable milk market and on the nature of their relationships with farmers. There is evidence that the German dairy industry is willing to contribute to a more sustainable and more robust milk market, but the enterprises mostly regard other market actors as more important. According to this survey, consumers will tend to opt for more sustainable milk products in future and there are possibilities to raise the willingness to pay.
