Today, the demand for soybean for feed industry and food production in Germany is met by imports from South and North America. Soybean cultivation in Germany, although challenging, will be of interest in the future due to an increasing demand for non-genetically modified (NGM) soybeans. To meet this rising demand for NGM soybeans and to increase resource use efficiency there is a need to reduce soybean harvest losses arising from harvesting with combine harvester. The height of the first pod can be a major factor affecting harvest losses, especially when it is not possible to maintain a sufficiently low cutting height. From 2011 to 2013, six soybean varieties were cultivated using two cropping systems (conventional ‘CON’ and organic ‘ORG’) at the Osnabru ̈ck University of Applied Sciences in a randomized block design with four replications to investigate the effect of first pod height and plant length on harvest losses and the effect of the cropping system on these parameters. Before harvesting with an experimental harvester, 1.5 m2 per plot were harvested manually as a reference. First pod height, number of pods per plant and plant length were determined on 10 plants per plot. Over the three years of the study, the first pod height (10.4 cm) and plant length (81.4 cm) were on average higher under conventional conditions compared to organic cultivation (7.3 cm; 60.9 cm). On average, lower harvest losses (25.6% vs. 39.2%) and higher grain yields (20.8 dt ha−1 vs. 16.9 dt ha−1) were also observed under conventional cultivation. Varieties differed significantly in grain yield, first pod height and plant length. A high first pod height was related to a longer plant length and lower harvest losses at both sites. However, a high first pod height and a high plant length did not lead to higher grain yields on any of the plots. These results indicate that harvest efficiency can be improved by choosing varieties with long plant lengths if it is not possible to maintain a low cutting height when harvesting with a combine harvester.

Organic farming is often subject of heated scientific and public debates. This raises the question: How can scientists working in organic farming research achieve being impartial while simultaneously sharing enthusiasm about organic farming and promoting it as a solution to many of the problems of agricultural and food systems? Science needs to be unbiased and detached from its object of investigation. It should be hesitant to draw conclusions. Public statements must wait until evidence is strong and reproducible. Complex matters need to be communicated in a differentiated way that acknowledges pros and cons. Finally, science needs to follow a strict separation of facts and opinion. In which ways does this culture go hand in hand with a burning passion for organic farming?

This article explores the causes underlying a strong presence of violent non-state actors (VNSAs) in South America. Based on a case study of the border area between Colombia and Venezuela, the research relies on a broad empirical data collected from newspapers, official documents and interviews. The analytical perspective has been grounded on a theoretical framework of four dimensions: (i) funding and illegal activities, (ii) presence in strategic regions, (iii) low state presence and (iv) violence, which identifies different forms of presence of VNSAs. When questioned about how VNSAs create new forms of alternative governance in a territorial space of fragile statehood, the results tend to reveal a context in which state governance seems to overlap the alternative and illegal governance of VNSAs, creating a fragile and hybrid governance in the region.

Do refugee inflows have an effect on state fragility? In this article I examine whether refugee inflows, commonly associated in the literature with economic and cultural pressures, result in a more fragile state by means of increased violent group grievance. Violent group grievance captures a distinct form of intrastate violence, specifically small-scale hate crimes and ethnic group clashes associated with powerlessness and discrimination. The main hypothesis in this paper is that refugee inflows may increase violent group grievance.

I examine the effect of refugee inflows on the level of domestic violent group grievance using quantitative analyses based on original large-N datasets and cross-sectional longitudinal models to fill gaps in the literature on state fragility. This study controls for alternative explanations and covers the time period between 2006 and 2014. The analysis results confirm the main hypothesis of this paper.
