Box 1. Definitions

Throughout this module, the terms 'multidisciplinary', 'interdisciplinary' and 'transdisciplinary' are used with specific and distinct meanings. While these terms may appear synonymous, they represent clearly differentiated approaches to research and problem-solving. The following general definitions provide clarity on their usage within this context:

Multidisciplinary research: An approach that draws upon knowledge and methodologies from multiple academic disciplines to examine a common theme or problem. In this model, each discipline contributes its unique perspective while maintaining its distinct boundaries and methodologies.

Interdisciplinary research: A form of integrative research that combines and synthesizes different, sometimes contrasting, disciplinary methods, models, and research paradigms (e.g. natural versus social sciences). This approach aims to create new knowledge and theory by addressing a common research problem through the integration of diverse disciplinary insights.

Transdisciplinary research: A holistic and participatory form of integrative research that transcends traditional academic boundaries. This approach combines knowledge from both academic and non-academic sources (such as community stakeholders) to address complex, real-world problems. It aims to create new knowledge and theory while working towards practical solutions through a unified, systems-based perspective.

These definitions serve as a general guide to understanding the precise application of these terms within the module.

The One Health High-Level Expert Panel (OHHLEP)1 defines One Health as:

"...an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems. It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and inter-dependent. The approach mobilizes multiple sectors, disciplines and communities at varying levels of society to work together to foster well-being and tackle threats to health and ecosystems, while addressing the collective need for clean water, energy and air, safe and nutritious food, taking action on climate change, and contributing to sustainable development."1
