Social research to understand farmer and agricultural stakeholder attitudes towards bovine tuberculosis vaccination of cattle.

BACKGROUND: This social research study employed a behavioural insights framework, Easy, Attractive, Social, Timely ('EAST'), to identify cues that may influence farmer and stakeholder attitudes towards the deployment of CattleBCG vaccine. METHODS: The EAST framework was employed to develop policy scenarios consisting of several cues likely to affect vaccine uptake. These scenarios consisted of a government-led approach, an individual farmer-led approach, and a third approach, also farmer-led but organised collectively. The government approach was mandatory, while the farmer-led approaches were both voluntary. The scenarios were tested during farmer participatory workshops (n = 8) and stakeholder interviews (n = 35). RESULTS: Overall, the EAST framework provided a useful approach for gathering behavioural insights around attitudes towards cattle vaccination. We found an overall receptiveness towards the idea of vaccinating cattle against bovine tuberculosis, particularly where clear, transparent messaging around the likely efficacy is mobilised, where clarity around potential implications for trading is provided, and where vaccine doses are provided free of charge and administered by veterinarians and veterinary technicians. In general, these factors were a pre-requisite to a mandatory (government-led) national approach, which was the preferred deployment mechanism among farmers and stakeholders. However, these conditions would also likely facilitate a voluntary vaccination programme. LIMITATIONS: Trust in those involved in delivering a vaccine programme and trust in the vaccine itself represent a crucial aspect of farmer and stakeholder attitudes towards cattle vaccination; however, this aspect was not covered by the EAST framework. CONCLUSION: EAST provided a novel framework for examining attitudes towards cattle vaccination with CattleBCG, although we recommend incorporating a 'trust' component in future iterations.

Collection of human and environmental data on pesticide use in Europe and Argentina: Field study protocol for the SPRINT project.

Current farm systems rely on the use of Plant Protection Products (PPP) to secure high productivity and control threats to the quality of the crops. However, PPP use may have considerable impacts on human health and the environment. A study protocol is presented aiming to determine the occurrence and levels of PPP residues in plants (crops), animals (livestock), humans and other non-target species (ecosystem representatives) for exposure modelling and impact assessment. To achieve this, we designed a cross-sectional study to compare conventional and organic farm systems across Europe. Environmental and biological samples were/are being/will be collected during the 2021 growing season, at 10 case study sites in Europe covering a range of climate zones and crops. An additional study site in Argentina will inform the impact of PPP use on growing soybean which is an important European protein-source in animal feed. We will study the impact of PPP mixtures using an integrated risk assessment methodology. The fate of PPP in environmental media (soil, water and air) and in the homes of farmers will be monitored. This will be complemented by biomonitoring to estimate PPP uptake by humans and farm animals (cow, goat, sheep and chicken), and by collection of samples from non-target species (earthworms, fish, aquatic and terrestrial macroinvertebrates, bats, and farm cats). We will use data on PPP residues in environmental and biological matrices to estimate exposures by modelling. These exposure estimates together with health and toxicity data will be used to predict the impact of PPP use on environment, plant, animal and human health. The outcome of this study will then be integrated with socio-economic information leading to an overall assessment used to identify transition pathways towards more sustainable plant protection and inform decision makers, practitioners and other stakeholders regarding farming practices and land use policy.

Sediment source fingerprinting: benchmarking recent outputs, remaining challenges and emerging themes.

PURPOSE: This review of sediment source fingerprinting assesses the current state-of-the-art, remaining challenges and emerging themes. It combines inputs from international scientists either with track records in the approach or with expertise relevant to progressing the science. METHODS: Web of Science and Google Scholar were used to review published papers spanning the period 2013-2019, inclusive, to confirm publication trends in quantities of papers by study area country and the types of tracers used. The most recent (2018-2019, inclusive) papers were also benchmarked using a methodological decision-tree published in 2017. SCOPE: Areas requiring further research and international consensus on methodological detail are reviewed, and these comprise spatial variability in tracers and corresponding sampling implications for end-members, temporal variability in tracers and sampling implications for end-members and target sediment, tracer conservation and knowledge-based pre-selection, the physico-chemical basis for source discrimination and dissemination of fingerprinting results to stakeholders. Emerging themes are also discussed: novel tracers, concentration-dependence for biomarkers, combining sediment fingerprinting and age-dating, applications to sediment-bound pollutants, incorporation of supportive spatial information to augment discrimination and modelling, aeolian sediment source fingerprinting, integration with process-based models and development of open-access software tools for data processing. CONCLUSIONS: The popularity of sediment source fingerprinting continues on an upward trend globally, but with this growth comes issues surrounding lack of standardisation and procedural diversity. Nonetheless, the last 2 years have also evidenced growing uptake of critical requirements for robust applications and this review is intended to signpost investigators, both old and new, towards these benchmarks and remaining research challenges for, and emerging options for different applications of, the fingerprinting approach.
