The Loktak lake represents a distinctive topography of an intermontane basin resting on the Eocene rock of the Disang Group. Geologically, the lake was tectonically formed, during the Quaternary period, along with linear depression shaped Imphal Valley and subsequent impounding of the water drained out by the centripetal drainage from the hill areas. This largest freshwater lake in northeast India is well known for its rich biodiversity and as a testament to the rich cultural heritage of Manipur. Many attempts have been made to study this lake from the perspectives of development, ecology, tourism, and environment. However, there is dirt on a scientific paper that explores Loktak lake as a geoheritage site encompassing the cultural milieu. In this backdrop, the proposed paper aims to explore this Ramsar site as a geoheritage site, exposing the intricate relationship between the Loktak Lake, indigenous communities in its littoral, their cultural practices, the ecosystem services provided by the lake, and emerging avenues for sustainable geotourism. While adopting a multidisciplinary approach, this paper will investigate the historical significance of Loktak Lake, tracing its cultural importance through time, and examine the associated indigenous narratives, traditional knowledge systems, and rituals related to the lake, which in turn shall elucidate the cultural values embedded within its physical as well as cultural landscapes. The impact of natural and human activities on Loktak lake and the importance of community participation in the conservation and management of Loktak lake as a geoheritage site are important for developing sustainable strategies for the protection and promotion of cultural heritage within the lake's ecosystem. This paper primarily contributes to the broader discourse on geoheritage conservation by showcasing Loktak lake as a paradigmatic case study through a cultural lens. The study underscores intrinsic linkages between people around Loktak lake, as well as its culture and the landscapes. As such, the paper suggests an urgent need to advocate for recognising and preserving Loktak lake as a priceless cultural asset for future generations.
