This study critically maps the epistemological development of vernacular architecture and cultural heritage studies (2001–2025). It examines thematic trajectories, scientific collaboration, geographical imbalances, and epistemic inequalities while assessing the recognition of local communities as knowledge-bearing actors.
A reflective–critical bibliometric analysis of 273 Scopus-indexed articles was conducted using PRISMA procedures. Co-authorship, co-citation and keyword co-occurrence networks were generated through VOSviewer. Interpretation draws on decolonial theory, epistemic justice and Global South epistemologies.
Five thematic clusters structure the field: (1) descriptive, local, and symbolic approaches; (2) technocratic–institutional conservation; (3) socio-ecological and participatory approaches; (4) historic preservation, materiality and constructions; and (5) rurality, governance and peripheral heritage. Technocratic paradigms dominate network centrality, while community-oriented and decolonial perspectives remain peripheral. Notably, no decolonial cluster emerged, indicating that such discourse has yet to gain thematic visibility in the fieldScientific collaboration is heavily concentrated in Global North institutions, reinforcing structural asymmetries. Nevertheless, an emerging shift recognises communities not merely as data sources but as epistemic contributors.
The study positions bibliometrics as a critical tool for uncovering representational inequalities and advancing more inclusive knowledge systems.
It encourages the integration of epistemic justice and decolonial principles in heritage practice to support socially grounded and community-based preservation efforts.
Strengthening community agency in knowledge production enables more equitable, context-sensitive and culturally rooted conservation.
This study introduces a decolonial, reflective-critical bibliometric framework that exposes power relations in global heritage research and advocates for plural, situated and community-derived ways of knowing.
