Abstract

Despite growing recognition of indigenous knowledge in climate adaptation, existing frameworks fail to distinguish genuine integration from tokenistic inclusion. This study develops the Knowledge Integration Maturity Model (KIMM)—a five-stage framework grounded in knowledge co-production theory, institutional innovation theory, and decolonization theory—featuring ten quantifiable dimensions anchored by indigenous decision-making power ratios. A PRISMA-compliant systematic review of the Scopus database identified 6324 records, of which 1980 were included for bibliometric analysis and 62 for in-depth qualitative synthesis. Applying KIMM to 85 global climate adaptation policies (1996–2025) across 45 countries, supplemented by case studies of Australia’s WALFA project, Colombia’s T-248 ruling, and Kenya’s Ogiek case, we find that global policies are transitioning from Level 3 (Inclusion) toward Level 4 (Collaboration), with a mean score of 58.7 (SD = 8.4) and none achieving Level 5 (Co-governance). Economic empowerment policies, though only 14.1% of the sample, demonstrate superior outcomes (mean = 61.9, Level 4 attainment = 50%), while budget control authority (D2 = 5.12) emerges as the critical bottleneck. A threshold effect at KIMM = 60 marks the shift from symbolic participation to substantive power-sharing, evidenced by the 36-point gap between WALFA (78) and Ogiek (42). These findings extend knowledge co-production theory by identifying structural preconditions for genuine collaboration, enrich institutional theory by revealing sequential change patterns where resource redistribution lags behind legal recognition, and operationalize decolonization theory through measurable indicators. The KIMM framework provides policymakers with diagnostic tools to advance from recognizing knowledge to empowering communities through institutionalized power redistribution.
