Enabling transdisciplinary research collaboration for planetary health: insights from practice at the environment-health-development nexus

In recent decades, transdisciplinary research has been increasingly recognised as necessary to produce solutions for sustainable development; however, implementation challenges remain. The emerging field of planetary health offers a unique lens to guide a new synthesis of perspectives, recognising interlinkages between environmental and human health, and interdependence across global development contexts, that is, at the environment-health-development nexus. This broad, practice-based literature review consolidates learnings from previous transdisciplinary research across these diverse yet interrelated fields, and aims to deepen understanding of, and identify opportunities for, enabling collaborative practice. This review found structural, relational, and individual factors enabling and constraining collaboration. Local research contexts and academia's disciplinary traditions posed structural constraints that required relational efforts at the project, organisational and individual levels to address. This analysis revealed strategic opportunities for funding programs and researcher training that can be leveraged to increase capacity for relational work, further enabling collaboration in transdisciplinary research.
