COVID-19 and changes in global agri-food trade
Engemann, Helena; Jafari, Yaghoob (2022-04-09)COVID-19 has raised questions about the resilience of agri-food trade to global shocks to the system. This paper analyses the changes in agri-food trade (values, extensive and intensive margin, and diversification) during ... -
Differences among domestic chicken breeds in tonic immobility responses as a measure of fearfulness
Tiemann, Inga; Becker, Senta; Fournier, Jocelyn; Damiran, Daalkhaijav; Büscher, Wolfgang; Hillemacher, Sonja (2023-04-04)Background: One priority for animal welfare is for animals to experience less fear, especially during human contact. For domestic animals, breeds that are less fearful may provide genetic resources to develop strains with ... -
Evaluations of agri-environmental schemes based on observational farm data: The importance of covariate selection
Uehleke, Reinhard; Petrick, Martin; Hüttel, Silke (2022-01-13)Evaluations of agri-environmental schemes (AES) based on observational farm data generally use a matching algorithm for comparing participating and non-participating farms. To mitigate the potential post-matching covariate ... -
Exploring animal genetic resources of the domestic chicken and their behavior in the open field
Tiemann, Inga; Becker, Senta; Büscher, Wolfgang; Meuser, Verena (2022-02-04)Animal welfare is of general interest, and in the farming arena, efforts have increased to create optimal conditions for poultry production. Detailed and standardized studies on specific behavioral issues, such as fear, ... -
Glucocorticoids in relation to behavior, morphology, and physiology as proxy indicators for the assessment of animal welfare: A systematic mapping review
Tiemann, Inga; Fijn, Lisa; Bagaria, Marc; Langen, Esther; van der Staay, F. Josef; Arndt, Saskia; Leenaars, Cathalijn; Goerlich, Vivian (2023-01-06)Translating theoretical concepts of animal welfare into quantitative assessment protocols is an ongoing challenge. Glucocorticoids (GCs) are frequently used as physiological measure in welfare assessment. The interpretation ... -
Improvement of Piglet Rearing's Energy Efficiency and Sustainability Using Air-to-Air Heat Exchangers: A Two-Year Case Study
Deeken, Hauke; Lengling, Alexandra; Krommweh, Manuel; Büscher, Wolfgang (2023-02-11)Pig farming in mechanically ventilated barns requires much electricity for ventilation or exhaust air purification. Furthermore, thermal energy is needed to fulfill the animals’ temperature requirements, especially in ... -
Jumping on the Bandwagon of Responsibility – Or Not?: Consumers' Perceived Role in the Meat Sector
Klink-Lehmann, Jeanette; Langen, Nina; Simons, Johannes; Hartmann, Monika (2022-05-21)It is evident that sustainable meat consumption and production require shared responsibility for actions and consequences by consumers and producers. Therefore, this study aimed to identify the relevant focus areas within ... -
One-Time Acidification of Slurry: What Is the Most Effective Acid and Treatment Strategy?
Overmeyer, Veronika; Kube, Anita; Clemens, Joachim; Büscher, Wolfgang; Trimborn, Manfred (2021-06-28)Acidification of slurry is a common practice to reduce ammonia and methane emissions. Sulfuric acid is usually used for this process. However, this has been criticized due to the high sulfur input into soils. Therefore, ... -
Recovering from Financial Implications of Flood Impacts: The Role of Risk Transfer in the West African Context
Wagner, Simon; Thiam, Sophie; Dossoumou, Nadège; Hagenlocher, Michael; Souvignet, Maxime; Rhyner, Jakob (2022-07-10)In many West African river basins, households regularly experience floods and the associated impacts. In the absence of widely accessible formal risk transfer mechanisms (e.g., insurance), households often have to cope ... -
Rural livelihoods, community-based conservation, and human–wildlife conflict: Scope for synergies?
Meyer, Maximilian; Börner, Jan (2022-08-01)Halting biodiversity loss is a major contemporary challenge. Nature protection can help conserve biodiversity, but increasing wildlife numbers inside protected areas and shrinking habitats intensify interactions between ... -
Sustainable Innovations: A Qualitative Study on Farmers’ Perceptions Driving the Diffusion of Beneficial Soil Microbes in Germany and the UK
Ploll, Ursula; Arato, Miguel; Börner, Jan; Hartmann, Monika (2022-05-10)Legislation and consumer preference for more sustainability in the food system require farmers to adopt more stringent sustainably measures without sacrificing business profitability. Scientific and technological ... -
Triggering cognitive dissonance with textual information and images: Data from three experiments with meat-eaters
Weingarten, Nina; Lagerkvist, Carl-Johan; Meraner, Manuela; Hartmann, Monika (2023-04-05)This article presents data from three experiments in which we triggered and measured cognitive dissonance in meat-eaters. Cognitive dissonance is a well-established concept in the social psychology literature; however, ... -
Unusually warm winter seasons may compromise the performance of current phenology models: Predicting bloom dates in young apple trees with PhenoFlex
Fernandez, Eduardo; Schiffers, Katja; Urbach, Carsten; Luedeling, Eike (2022-07-15)Phenology models are crucial tools for assessing climate change impacts in forestry, ecology and agriculture. Such models are typically calibrated with observational or experimental data and validated with a set of independent ... -
