Cannabis cultivation in the world: heritages, trends and challenges

Pierre-Arnaud Chouvy

EchoGéo· 2019

Sets out the state of knowledge on cannabis cultivation as a global phenomenon at the cusp of legalisation. Reviews the unresolved Cannabis taxonomy debate (monotypic Small versus polytypic Hillig, Clarke and Merlin) and the inconsistency between the sativa/indica taxa as used in botany and the sativa/indica labels as used in the trade, citing Sawler et al. 2015 to show that strain labels often do not reflect a meaningful genetic identity. Traces the modernisation of cannabis cultivation from the 1970s sinsemilla shift in Mexico, Colombia, Jamaica and California, through Skunk #1 and the first modern hybrids, the introduction of cloning in the 1990s, the development of feminised seeds in 1999, and the more recent spread of autoflowering varieties. Catalogues the principal cannabis end products: herbal cannabis, sieved hashish (Morocco, Lebanon, Afghanistan), hand-rubbed charas (India, Nepal), bhang, and the modern solvent-based and solventless concentrates. Documents how production estimates from UNODC, INCSR and national authorities are derived almost entirely from eradication figures rather than from systematic ground or remote-sensing surveys, and shows how the Moroccan Rif estimates have remained implausibly stable across years of widely varying eradication intensity. Maps the global state of legal recreational cannabis, medical cannabis and hemp as of 1 January 2019. Argues that legalisation in the Global North is creating disruptive consequences for traditional cannabis farmers in the Global South: the loss of the competitive advantage of illegality, the threat to landraces from imported hybrid germplasm, the carbon footprint of indoor cultivation, and the rise of corporate consolidation. Foundational reference for the wiki's framing of landrace conservation under legalisation.
