Why Casamance is a growing region

The UN study The Drug Nexus in Africa (1999, p. 23), whose Senegal field work was done by the Observatoire géopolitique des drogues, names the southern area of Casamance as Senegal's major cannabis-producing area and the strip along the Gambia's southern border up to the Karone river islands as the second.
The UNODC review of 2006 (p. 71) lists the Casamance region, the southern border with the Gambia, Kolda and the Karones among the places where cannabis is grown.
Evans (2003, pp. 10–11) places the main growing areas in the north and west of Ziguinchor region, around Kafountine and the Karone Isles. Tine and Diatta (2018) studied growing on the Bliss islands, part of the Karones, in the commune of Kafountine.
Growing since 2000 is reported by Agence France-Presse at Kouba (2020) and by the army, through the Senegalese press, in the north of Bignona department (2015, 2021, 2022, 2026) and on the Karone islands (2025).
The herbarium sheet Vanden Berghen 9803 (1993), from Abéné, records a plant grown "pour la drogue" in a market garden. It confirms growing on the coast in 1993; it did not by itself put the region on the map.

How the border is drawn

The border is a proxy built from administrative units, not from accession points: Ziguinchor Region (OpenStreetMap relation 2909649), Bounkiling Department in Sédhiou Region (relation 8759643) and Médina Yoro Foulah Department in Kolda Region (relation 5557141), together about 14,900 km², the figure in the infobox. The official areas are 7,339 km² for Ziguinchor Region (ANSD, 2019) and 2,864 km² for Bounkiling (ANSD, 2023/24); Médina Yoro Foulah covers 34 per cent of Kolda Region's 13,771 km² (ANSD, 2024).
Every growing place below the scale of a region that the sources name since 2000 lies in Ziguinchor Region, except Saré Koundian. The two departments to the east carry the strip along the Gambia's southern border that the UN study of 1999 named as Senegal's second producing area.
Sédhiou town, where Collomb and his colleagues found scattered growing in 1962, and Saré Koundian, in Kolda Region near the border with Guinea, where the army destroyed fields in 2025, lie outside the line. Both are named in the article.
The infobox point (12.99, −15.75) is the centre of the border polygon.

Growing status

The status is Active: the army reports destroying cannabis fields in Bignona department in September and October 2026. No source says that growing has stopped.

The rebellion

The article states as plain fact only that the MFDC has waged a separatist rebellion since 1982 (Evans 2003; AFP 2026). Every statement about the rebels and cannabis is attributed to the person or body that made it, with the main positions side by side: Evans (2003) and UNODC (2006, 2007) judge its importance debatable or exaggerated; a gendarmerie officer's thesis (Faye 2006) and Duvall (2019), who cites it, make the link firmly; the government and the army describe the crop as the rebels' resource; the MFDC rejects the accusations; Tine and Diatta (2018) doubt the link for the Karone islands and call eradication a pretext to retake territory.
Marut's thesis of 1999 and his book of 2010, the main scholarly sources on the subject, were not read. His views are given as Evans (2003) and the Senegalese site Senego (2022) report them.

Sources

Evans (2003) was read in the ODI PDF; page numbers are the printed ones. Its section on cannabis draws on Marut (1999), Hall (1999), Oxfam GB (1998) and personal communications from Foucher and Anderson.
Faye (2006) is a master's thesis in security studies at the Naval Postgraduate School by a lieutenant colonel of the Senegalese National Gendarmerie, read in the NPS Calhoun copy. Its cannabis passages (pp. 53–55) rest on Marut (1999), Evans and the Senegalese press.
Tine and Diatta (2018) was read in the copy on the repository of the Université Assane Seck de Ziguinchor. The running head (vol. 8, no. 10, October 2018, pages 1–13) and the issue's front matter (no. 11, November 2018, p. 31) disagree; page numbers given are the article's own, and the DOI in the running head belongs to another paper. The production figures are the authors' estimates, without method or year.
Biagui (2022) is an opinion piece by a former secretary-general of the MFDC; the saved copy begins after the opening paragraphs.
Army operations are known from the Senegalese press (APS, APA, Le Soleil, Senego, Seneweb, Dakaractu), which mostly relays communiqués of the army's information office. Areas are given only where the report gives them ("several hectares", "more than a hectare").
ANSD editions disagree on the regional areas (Sédhiou 7,330, 7,341 or 7,353 km²; Kolda 13,718 or 13,771 km²); the editions cited are named in the references.

A cable of the United States embassy in Dakar of 2006, known only from a leak reproduced by a news site.
The Afrik.com report of 8 May 2026 on the operation in Bignona, which could not be read; the operation is given from the AFP report of 15 May 2026.
The Geopolitical Drug Dispatch article on the Casamance rebels and cannabis (no. 53), cited in the UN study of 1999, which was not found.

Open questions

Whether the Karone islands and the north of Bignona department (Nord-Sindian) should be treated as growing areas of their own within the region is not settled.
