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.

Bengal District Gazetteers: Rajshahi (1916)
The Bengal District Gazetteers: Rajshahi is a district gazetteer compiled by the Indian Civil Service officer L. S. S. O'Malley and published at Calcutta in 1916. It is one of the revised Bengal District Gazetteers, the standardised provincial reference series issued under the authority of the Government of Bengal. The volume describes Rajshahi, a district of the Rajshahi Division of Bengal Presidency on the right bank of the Padma; the district lay in eastern Bengal at the time of writing and today forms part of Bangladesh.
Unlike most of the series, the volume is a cultivation source of the first rank. Rajshahi contained the ganja mahal, the Government-supervised tract in the Naogaon subdivision that was the licensed source of ganja for the greater part of British India, and O'Malley gives it a chapter of its own (ch. XII, "The Ganja Mahal," pp. 134–144). That chapter is the volume's principal cannabis content; shorter references occur in the excise subsection of the General Administration chapter (pp. 132–133), in the account of the district's people (a ganja-using religious sect, p. 64), and in the place-by-place gazetteer (the Raja of Tahirpur as a member of the Indian Hemp Drugs Commission, p. 191). O'Malley states that the chapter was compiled chiefly from Hem Chunder Kerr's 1877 cultivation survey and from the report of the Indian Hemp Drugs Commission of 1894, and it is best read as a 1916 administrative digest of those two sources rather than as an independent inquiry. read more →
