Farmers concerns in relation to organic livestock production

The study describes organic producers' perceptions of organic livestock production, product commercialisation, use of contentious inputs such as allopathic antibiotics, antiparasitics and vitamins and bedding materials availability in Mediterranean (MED) and North/Western European (NWE) countries. A total of 426 MED (46.2%) and NWE (53.8%) responses were analysed revealing more difficulty finding information on alternatives to antiparasitics and antibiotics than on bedding materials. They identified 'feeding/nutrition', 'animal health' and 'welfare' as the most relevant topics in their farms. Whereas ruminants and monogastrics farmers in the NWE region also indicated 'organic regulation' as relevant, farmers rearing ruminant species in the MED region identified farm profitability and commercialisation. Farmers still mainly relied in conventional treatments but they often applied phytotherapy, although >61% of the participants did not treat their animals in the last year. If treated, most of them administered on average one course of antibiotic treatment per animal (>62%). In the MED region, the main sources of information on alternative treatments were veterinarians (>60%) and the Internet (>32%). In the NWE region, it was other farmers for producers including ruminant species (>63%) and veterinarians (>77%) for monogastric farmers. In the NWE region, direct commercialisation and through a cooperative and/or food industry were the most frequent channel used; while, in the MED region, they were the food industry and/or direct commercialisation. In conclusion, this survey provides novel cross-European insights into organic livestock producers' concerns. A particular value of the survey is that MED countries, which are often underrepresented, were well sampled.

Current use of copper, mineral oils and sulphur for plant protection in organic horticultural crops across 10 European countries

The use of several plant protection inputs of mineral origin, such as copper, sulphur or mineral oils is seen as contentious by many consumers and stakeholders within the organic sector. Although the use of these inputs is legal in organic systems and also applied in non-organic agriculture, their use by organic growers raises questions for organic practice, which aspires to be free from toxic, non-renewable chemicals. Data on the current use of permitted plant protection inputs is currently scarce, especially in horticulture where chemical inputs deserve special attention since horticultural products are often readily edible. A mapping of the use of copper, sulphur and mineral oils was conducted by collecting expert knowledge across 10 European countries during May–October 2018, i.e. before the limitation of copper use to 4 kg ha−1 year−1 from February 1, 2019. Results show that copper is widely used by Mediterranean organic growers in citrus, olive, tomato and potato production. The annual limit of 6 kg ha−1 year−1 was not always respected. We also found that tomato producers apply high amounts of copper in winter crops in greenhouses. Mineral oils are applied to control scales, mites and whiteflies. Sulphur is also commonly used by organic vegetable growers, especially in greenhouses. We conclude that the high usage found in various different crops (especially Mediterranean crops) confirms the need for researching alternatives. © 2020, Springer Nature B.V

Design considerations for haptic-enabled virtual reality simulation for interactive learning of nanoscale science in schools

This paper reports on a study which investigated whether the addition of haptics (virtual touch) to a 3D virtual reality (VR) simulation promotes understanding of key nanoscale concepts in membrane systems for students aged 12 to 13. We developed a virtual model of a section of the cell membrane and a haptic enabled interface that enables students to interact with the model and to manipulate objects in the model. Students, in two schools in England, worked collaboratively in pairs on activities designed to develop their understanding of key concepts of cell membrane function. Results of pre-and post-tests of conceptual knowledge and understanding showed significant knowledge gains but there were no significant differences between the haptic and non-haptic condition. However, findings from observation of the activities and student interviews revealed that students were very positive about using the system and believed that being able to feel structures and manipulate objects within the model assisted their learning. We examine some of the design challenges and issues affecting the perception of haptic feedback
