Why It Matters
Interdisciplinary research combines insights from multiple academic disciplines. Transdisciplinary research goes a step further: it integrates academic knowledge with the experiential knowledge of non-academic stakeholders—communities, policymakers, practitioners, Indigenous peoples—to produce understanding that neither group could generate alone.
The rationale is both epistemological and practical. Epistemologically, complex sustainability problems involve value dimensions, local knowledge, and political dynamics that academic research alone cannot capture. A fisheries biologist studying fish stocks lacks the embodied knowledge that a lifetime fisher possesses about seasonal patterns, habitat changes, and ecosystem relationships. A climate modeler projecting rainfall changes lacks the agricultural knowledge that farmers hold about how their specific soils respond to different moisture conditions.
Practically, research that is co-produced with stakeholders is more likely to be used. Decades of evidence show that "science-push" models—where researchers produce knowledge and hand it to practitioners—fail more often than they succeed. Research that is jointly designed, jointly conducted, and jointly interpreted has higher uptake because stakeholders have ownership of both the process and the findings.
Yet transdisciplinary research is extraordinarily difficult to do well. It requires navigating power asymmetries between academics and community members, reconciling different evidence standards, managing timelines that academic incentive structures do not support, and publishing results in forms that both academic journals and community partners value.
The Science
Tensions in Transdisciplinary Knowledge Co-Production
Harris et al. (2024), with 27 citations, provide the most comprehensive review to date of the tensions inherent in transdisciplinary sustainability research. Their analysis identifies six structural tensions that cannot be resolved—only managed:
The review argues that acknowledging these tensions explicitly—rather than pretending they can be solved—is the first step toward more honest and productive transdisciplinary practice.
Co-Production with Indigenous Peoples
Felicien et al. (2024), with 1 citation, develop the Transdisciplinary Adaptive Participatory Action Research Approach (TAPARA) specifically for knowledge co-production with Indigenous Peoples. TAPARA addresses a critique that has haunted participatory research: even well-intentioned co-production can reproduce colonial dynamics if it extracts Indigenous knowledge to serve academic purposes without genuinely serving Indigenous communities.
TAPARA operationalizes respect through structural features: Indigenous communities define the research questions (not academics); traditional knowledge governance protocols (who may share what knowledge, under what conditions) are binding on the research process; and outputs include forms that communities value (land management plans, educational materials) alongside academic publications.
Applied in Indigenous communities in Latin America, TAPARA demonstrates that genuine co-production requires fundamental shifts in who controls the research agenda—not merely adding community consultations to a researcher-designed project.
Marine Socio-Ecological Systems
Matsubara et al. (2025) reflect on the evolution of marine socio-ecological systems science from primarily interdisciplinary approaches toward genuinely transdisciplinary ones. The Marine Socio-Ecological Systems (MSEAS) symposium series, spanning 2016-2024, provides a longitudinal view of how a research community gradually incorporates non-academic knowledge.
The transition has been uneven: fisheries science has advanced furthest in stakeholder engagement (fishing communities are natural partners), while marine biodiversity conservation and ocean governance remain more academically driven. The paper identifies a critical bottleneck: marine governance decisions (fishing quotas, marine protected areas, shipping lanes) are made by national and international bodies that operate on different timescales and evidentiary standards than either academic research or community knowledge.
Participatory Migration Research
Smith and Wool (2025), with 1 citation, critically examine participatory and co-productive methods in migration research—a field where the "research subjects" (migrants, refugees, displaced persons) are particularly vulnerable to extractive research practices. The paper distinguishes between research "on" migrants and research "with" migrants, arguing that the migration studies field still predominantly conducts the former while rhetorically claiming the latter.
The analysis identifies concrete methodological innovations: peer research (training migrants as researchers who investigate their own communities), photovoice (participants document their experiences through photography and narrative), and community advisory boards that have genuine decision-making power over research design and dissemination.
Transdisciplinary Research Design Spectrum
<| Dimension | Consultative | Collaborative | Co-Productive | Community-Led |
|---|---|---|---|---|
| Research questions | Academic-defined | Jointly refined | Jointly designed | Community-defined |
| Methods | Academic standard | Adapted for context | Mixed (academic + local) | Community-appropriate |
| Data collection | By researchers | Supported by stakeholders | Joint teams | By community members |
| Analysis | Academic | Validated by stakeholders | Joint interpretation | Community-led |
| Outputs | Academic publications | Policy briefs + papers | Multiple formats | Community priorities first |
| Power | Academic-controlled | Shared in theory | Genuinely negotiated | Community-controlled |
What To Watch
The institutionalization of transdisciplinary research is the key trend to watch. Funding agencies (EU Horizon Europe, UK Research and Innovation, NSF) increasingly require "pathways to impact" and stakeholder engagement plans—but these requirements often reduce co-production to a checkbox rather than a genuine methodological commitment. Watch for whether these requirements evolve toward evaluating the quality of co-production processes, not just their existence. The TAPARA model for Indigenous knowledge co-production is likely to influence research ethics frameworks globally, as Indigenous data sovereignty movements demand structural changes to how research involving Indigenous knowledge is governed. Expect growing tension between the time and resources required for genuine co-production and the productivity metrics that academic careers depend on.
