The provinces that could assist in realising this goal are KwaZulu-Natal, the Eastern Cape and Limpopo.
There are about 1.6 million to 1.8 million hectares of underutilised land in these provinces which could be put into full production.
Changing views on cannabis
In addition to the aforementioned crops, changing perceptions about cannabis around the globe, and its growing value raises a question of whether South Africa should put concerted effort into research on this crop so that policymakers can better assess if its production benefits could be balanced by measures to mitigate unintended consequences.
In a recent Constitutional Court ruling, the private use of cannabis was decriminalised in South Africa, but the conditions and boundaries still need to be considered and legislated.
Furthermore, the decriminalisation for private use might not be where the commercial value lies.
The focus should rather be on exploring the possible benefits for the country through the controlled, international trade in cannabis and its products, and also medicinal use purposes in the domestic market.
What about export?
For international trade, the export markets would include the US, Canada, and China, as some regions within these countries have decriminalised cannabis.
In the state of California within the US, the value of the cannabis industry was estimated at US$3bn in 2017.
In China - a grower of nearly half the world’s legal hemp - the sales of textile fibre made from the plant’s stalk - totalled US$1.2bn.
South Africa already trades agricultural commodities with the aforementioned countries. Hence, their increasing desire for cannabis and its product is interesting, as it would offer extra value if South Africa was to follow the route of producing the crop for international trade, and medicinal use within a clearly regulated environment.
Start with research
Overall, we are not arguing for any particular policy position regarding cannabis, but rather for increased research, which would assist policymakers in evaluating the benefits, and possible unintended consequences of growing and trading cannabis.
This should take stock of the changing perceptions surrounding this crop globally, and its growing demand and commercial value.
In the coming years, depending on whether South Africa’s policy position on cannabis follows the global development, the ideal provinces would be Eastern Cape, KwaZulu-Natal and Limpopo due to favourable climatic conditions.
