The Water Wealth in Agriculture event was hosted in conjunction with the Simpson Centre for Food and Agricultural Policy, University of Calgary, and the Global Institute for Water Security, University of Saskatchewan. The event brought together a diverse set of stakeholders concerned about water management from the perspective of industry, government, and research. Roundtable discussions were facilitated to discuss problems and potential solutions regarding sustainable water management for agriculture, and water management more broadly.

Endemic infectious diseases remain a major challenge for dairy producers worldwide. For effective disease control programs, up-to-date prevalence estimates are of utmost importance. The objective of this study was to estimate the herd-level prevalence of bovine leukemia virus (BLV), Salmonella Dublin, and Neospora caninum in dairy herds in Alberta, Canada using a serial crosssectional study design.

This study examines the grazing management plans (GMPs) adoption and prioritization of environmental and economic objectives among U.S. cow-calf and stocker operations, utilizing 2020–2021 survey data and logistic regression analysis. Findings reveal regional adoption differences, with higher rates in the Midwest.
Operations with succession plans, larger grazing lands, and stocker activities are more likely to adopt GMPs. Operations with more privately owned land and smaller herd sizes prefer environmental goals, while those with less grazing land prioritize economic outcomes due to resource concerns. The study provides insights for policies promoting GMP adoption and sustainability in the U.S. beef sector.

To support farmers in their decisions related to Q fever, a dedicated economic assessment tool is developed. The present work describes the calculator, its economic rationale, and the supporting assumptions. The calculator integrates a yearly compartmental model to represent population dynamism and the main interactions between disorders linked to Q fever, especially reproductive disorders (abortion, retained foetal membranes, purulent vaginal discharge and endometritis, extra services, and calving–conception delays). The effects of the nontangible cost of the disease on human health, the welfare of the animals, and the workload of farmers were not integrated into the model. The model shows high-level sensitivity to the prevalence of Q fever in the herd prevaccination and to the costs of abortion and extra days of calving–conception intervals. Breakeven points, i.e., cost values that allow us to achieve positive vaccination benefits, are also reported. For herds with moderate or high prevalence rates of Q fever prevaccination (>30%), a vaccination benefit is observed. The vaccine should be considered a type of insurance in herds with low prevalence rates of Q fever prevaccination (≤20%). The calculator was developed to aid decision-making at the farm level, and no conclusion can be extrapolated as a generic trend based on the present work.

We are facing interdependent challenges that call for a shift in our agri-food system. And there is one way forward: the One Health way. Transitioning our food systems is a unique opportunity to implement cross sectorial public policies. It is time to focus on the potential to preserve and restore human, animal, plant and environmental health.

Veterinarians are a pivotal force in addressing animal health and welfare surveillance, with a critical role in improving public health security and increasing the profits of livestock farmers. Yet, the veterinary profession is adversely affected by personnel shortages, particularly in rural areas. Since the health of people, animals and their shared environment are interconnected in a One Health perspective, a set of policies are required to ensure public health by attraction and retention of veterinarians in rural areas. In France, a tutored internship programme, financially subsiding students and mentors to execute a training period in remote rural areas, was promoted to better integrate and retain veterinary students ending their veterinary training. This paper aims to evaluate how veterinarians’ tutored internships influences students’ choices for rural practice, using three different statistical methods derived from causal inference theory. Using survey data for the period 2016–2020, we show that: (i) the average effect of the tutored internship on veterinarians’ work in food animal sector is not significant; and that (ii) the tutored internship leads veterinarians with a low share of work in the food animal sector to have a rural practise after they graduated between 13 and 20% greater than those who did not participate in the tutored internship.
