Abstract

Linguistic, cultural and biological diversity often co-occur and frequently decline under similar pressures. This review synthesizes recent evidence on the patterns, processes and prospects of this intertwined diversity. The paper outlines historical roots of the field and summarize contemporary research that maps spatial overlap between biodiversity hotspots and language richness, examines scale effects and links language vitality with traditional ecological knowledge. The review clarifies philosophical and ethical foundations, emphasizing justice, rights, epistemic pluralism and stewardship. It then surveys methods for measuring trends including linguistic vitality indices, practice-based indicators and biocultural dashboards co-designed with communities. Policy connections are highlighted through evolving international frameworks that call for inclusive governance, secure tenure, mother-tongue education and locally led monitoring. Practical pathways include recognition of indigenous and community land and sea rights, partnership models for protected and conserved areas, community-based monitoring using multiple knowledge systems and support for culturally grounded livelihoods. The findings demonstrate the need for plural and functional metrics, direct and sustained finance to local institutions, safeguards for data sovereignty and implementation that links global targets to place-based action that can sustain diversity in nature, languages and cultures.
