Gazetteer
A gazetteer is a geographical and statistical reference work describing the places within a defined territory: their physical setting, history, population, administration, economy and notable sites, usually arranged as a systematic survey of a country, province or district. In British India the genre took institutional form in the district gazetteers, standardised volumes compiled by provincial governments to a fixed chapter scheme. Their chapters on agriculture, excise and the people of each district incidentally preserve much of the surviving record of the colonial ganja economy, which makes them a recurring primary source on this wiki. The volumes most relevant here are the early-twentieth-century gazetteers of Bengal and of the short-lived province of Eastern Bengal and Assam, several of which describe the licensed Ganja Mahal and the wider north Bengal cannabis belt. read more →

Cannabis eradications
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.
