Northern Laos}

Northern Laos

Southeast Asia - Lao Highlands

Rugged northern Lao uplands with long-cycle landraces still in cultivation, but under intense pressure from development, eradication, hybrid introgression and cheap Thai cannabis flooding the market; documentation and conservation are urgent.

Western Himalayas}

Western Himalayas

South Asia - Western Himalayas

Western Himalayan charas heartland where cultivation of high elevation, late-finishing NLD landraces is a part of everyday village life; law enforcement is a cat-and-mouse routine and male culling adds steady pressure. Documentation and conservation are needed.

We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge—preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
