One Welfare and Sustainability Center

The One Welfare and Sustainability Center (OWSC) is a unique center that brings together expertise is ecosystem health, global health and welfare, sustainable production and conservation of wildlife species. An important function of this center is to coordinate and manage all research being conducted by our partners and wildlife scientists through Ohio State to take advantage of the reputation, animal care and use committees, reputable research standards, and education mandates of the university.

The One Welfare and Sustainability Center facilitates a multi-disciplinary collaborative team of expertise capable of establishing health baselines through to addressing an urgent and critical need to monitor, diagnose, interpret, report, and make recommendations on managing our free-ranging environment against natural and anthropogenic stressors. We share this knowledge with our university, scientific and local communities.

What is One Welfare?

Assessing problems from a national, global and holistic perspective

One Welfare theory looks at issues from a wide, national, global and holistic perspective. The concept refers to not only animal welfare but includes human welfare and societal mental health, as well as environmental conservation.

Our goal is to critically and independently assess animals, environments and communities to ensure best practices, health and welfare, and conservation occur for all production species but also contribute broadly to the global knowledge required to sustainably preserve all ecosystems; as well as improve the lives of the human communities that live within the footprint of production. Veterinarians can complement One Welfare by value-adding to the work done by ecologists and biologists through the study of wildlife and production animal health and survivorship under normal and adverse environmental conditions.

Role of the Center

Members of the OWSC will collaborate with other tertiary, government, NGO’s and special interest groups, in times of anomalous or catastrophic events, to assist with creating informed strategies to mitigate short term and/or long-term negative impacts and determine risk factors. The role of the center:

  • Conduct appropriate research to advance the field of One Welfare
  • Interact with stakeholders, other academics and government  agencies involved with using or preserving our natural environment to knowledge share and achieve common goals
  • Educate at the community level on all aspects of One Welfare to raise awareness of issues for the current and future generations
  • Educate professional DVM and graduate students in the appropriate skills needed to contribute to maintaining and improving the health of ecosystem

Mission and Goals

Our mission is to become a center for species welfare and sustainability through research knowledge, training, outreach, and expertise within a network of animal researchers and managers while serving other species of conservation concern. 

  • Goal 1 - Establish the One Welfare Sustainability Center at Ohio State as the global leader in animal population health, welfare and sustainability, with an emphasis on their application to conservation-oriented systems.
  • Goal 2 - Develop a comprehensive training program in animal population health, welfare, and sustainability targeting professional Doctor of Veterinary Medicine (DVM) and graduate students, and veterinary clinical residents.
  • Goal 3 - Deliver global outreach in support of animal population health, welfare, and sustainability in production systems using novel species,
  • Goal 4 - Conduct outreach research and serve as the scientific liaison with our center partners in regions where the species of interest occur.
  • Goal 5 - Promote the OWSC to the industry stakeholders and universities and develop a collaborative relationship with existing bodies.

Our People

By virtue of the interdisciplinary nature of the field of One Welfare, this center is interdisciplinary. Areas of expertise within our ranks span veterinary medicine, conservation science, ecology and biology, the social sciences, economics, and education. The diverse personal and professional backgrounds of our members, partners and collaborators make us able to comprehensively use science from a range of perspectives to approach the potentially controversial topics and opinions that plague all wildlife and production systems, whether an endangered wild species under an anthropogenic stressor, an exotic species used in a high-end fashion industry, or a common domesticated production species housed in a system that is perceived to be inadequate.

Trainees

Dr. Brittany Fischer
Postdoctoral Scholar
fischer.747@osu.edu 

Dr. Brittany Fischer recently completed her PhD and is now a Postdoctoral Scholar in the One Welfare and Sustainability Center. Prior to beginning her PhD, Dr. Fischer earned her master’s and undergraduate degrees in Animal Sciences, studying animal welfare in a zoological setting.

The One Welfare and Sustainability Center provides comprehensive training and education programs aimed at fostering a deep understanding of the interconnectedness of human, animal, and environmental well-being. Our offerings span a wide range of disciplines, equipping individuals with the knowledge and skills needed to promote sustainability and conservation. 

  • VETPREV7710 - Ecosystem Health Conservation Medicine: Through lectures, readings, field practicum, discussions and self-directed learning, this elective course introduces the principles and practices of ecosystem health with emphasis on the role of the veterinarian. Conservation medicine will be examined using the One Health One Medicine paradigm.
  • VETPREV7700 - Aquatic Animal Health and Medicine: An entry-level class exposing professional veterinary and graduate students to the diverse field of aquatic animal health, medicine, and welfare. It aims to equip veterinarians with an interest in aquatic medicine and higher research degree earning students with an interest in the disease ecology of aquatic species to gain skills directly applicable to their profession. Concepts will cover principles of aquaculture, the natural aquatic environment, common diseases, and treatments.
  • VMCOLL6120 - One Health & One Welfare: Historical, philosophical and scientific developments that have led to our current understanding of animal welfare and how it should be assessed. An overview of the tenancies of One Health and One Welfare, the role of the veterinarian in a range of disciplines and how this framework may be applied to our everyday clinical practice.  
  • Zoo and Wildlife Conservation Medicine and Ecosystem Health Residency Program: A three-year, ACZM-accredited residency in Zoo and Wildlife Conservation Medicine and Ecosystem Health. This is a unique cooperative program between the Ohio State University College of Veterinary Medicine, the Columbus Zoo and Aquarium and the Wilds. This program provides trainees with coursework, zoological medicine training and field experience emphasizing a One Health approach to the study of nondomestic animal health and leading to a Master’s degree at the completion of the residency. This program is uniquely designed to train ACZM eligible candidates and prepare conservation medicine clinicians to advance the field through further research and training nationally and internationally.

  • One Welfare: Animal Welfare Residency Program: A three-year, ACAW accredited residency in  One Welfare - Animal Welfare. The goal is to train veterinarians in One Welfare, which looks at issues from a wider, national, global and holistic perspective, focusing on the inter-relationships between animal welfare, human wellbeing and the environment. The concept refers to not only animal welfare but includes human welfare and societal mental health, as well as environmental conservation. Graduates of the Program will be board eligible with the American Veterinary Medical Association (AVMA) Veterinary Board of Veterinary Specialties (VBVS) after the completion of a 3-year didactic and experiential individually tailored program that includes a Research Masters degree (MS) from the College of Veterinary Medicine at Ohio State University. 

 

Pending approval, this certificate will provide graduate-level and professional training in the emerging discipline of One Welfare as part of their degrees or in a non-degree earning modality. It is anticipated this training will be available globally through its unique online delivery methods. Participants will be able to earn the certificate without the need to enroll in a degree-seeking program. The outcome of this certificate will be valuable training in the application of One Welfare in the workplace.
