UNESCO Recognizes Mine-Akiyoshidai Karst Plateau: Systemic Gaps in Geopark Conservation and Indigenous Land Stewardship Remain

The Mine-Akiyoshidai karst plateau holds deep cultural significance for the Ainu and Yamaguchi indigenous communities, who have stewarded the land through traditional practices such as controlled burning and seasonal foraging. However, UNESCO’s geopark model rarely centers Indigenous knowledge, instead framing these landscapes as ‘scientific’ or ‘touristic’ resources to be managed by state and scientific authorities. This erasure mirrors colonial patterns of land appropriation, where Indigenous stewardship is dismissed in favor of extractive or commodified conservation models.

Karst landscapes in Japan have been shaped by centuries of human interaction, from the Ainu’s seasonal migrations to the Meiji-era industrialization that introduced limestone quarrying. The UNESCO Global Geopark program, launched in 2004, builds on earlier conservation models like Japan’s Natural Parks system (1931), which often prioritized scenic value over ecological integrity. Globally, karst regions have been sites of both cultural reverence and extractive exploitation, such as in Slovenia’s Postojna Cave system, where tourism has outpaced conservation efforts.

Comparative studies of karst geoparks reveal diverse conservation approaches: Slovenia’s Postojna Cave system balances tourism with cave ecosystem protection, while China’s South China Karst UNESCO site integrates geological tourism with local livelihoods. In New Zealand, Māori communities have successfully advocated for the inclusion of Indigenous knowledge in geopark management, such as the Te Wai Pounamu (South Island) model. Japan’s geopark system could adopt these cross-cultural lessons to move beyond tokenistic recognition toward genuine co-management with Indigenous peoples.

Scientifically, karst landscapes are critical for groundwater recharge, biodiversity hotspots, and carbon sequestration, yet their fragility is often underestimated in geopark designations. Studies show that limestone quarrying and agricultural runoff can disrupt karst hydrology, leading to sinkhole formation and loss of endemic species. UNESCO’s geopark criteria emphasize geological education and sustainable tourism, but lack enforceable standards for ecosystem protection or climate resilience, leaving karst regions vulnerable to degradation.

Artistically, karst landscapes have inspired centuries of Japanese poetry, painting, and folklore, from the ukiyo-e depictions of Mount Fuji to the haiku of Bashō, which often evoke the interplay of stone and water. Spiritually, karst formations are seen in Shugendō traditions as sites of ascetic practice and divine energy, where mountains are considered living deities. The Mine-Akiyoshidai plateau’s designation as a geopark risks reducing this rich cultural and spiritual tapestry to a mere ‘geological wonder,’ stripping it of its deeper meaning for local communities.

Future scenarios for Mine-Akiyoshidai must account for climate change, which threatens karst ecosystems through increased rainfall variability and soil erosion. UNESCO’s geopark model could evolve into a ‘living geopark’ framework, integrating Indigenous knowledge, citizen science, and adaptive management to address these challenges. However, without structural reforms—such as binding conservation agreements and revenue-sharing with local communities—the designation risks becoming a hollow accolade as industrial pressures intensify.

Marginalized voices—particularly Ainu communities, small-scale farmers, and local conservationists—are largely absent from the narrative, despite their direct stake in the plateau’s future. The Ainu, whose ancestral lands span Hokkaido and parts of Honshu, have faced historical erasure and continue to fight for recognition of their cultural heritage. Additionally, women-led conservation groups in Yamaguchi Prefecture, who have documented traditional ecological knowledge, are rarely consulted in geopark planning processes.
