There’s a right and a wrong way to go about things. Grahame Jackson patiently spells out the right way for Cameroon to get blight-resistant taro:
We have a world network for the improvement of edible aroids that includes, taro and cocoyam; Cameroon is not a member. But if someone in the government requested our help I am confident assistance would be given. The assistance would be varieties from the Pacific that have been bred for resistance to taro leaf blight. The introduction of the varieties has to be done through govt agencies because of plant quarantine concerns. Import licences have to be issued, IP documents signed, phytosanitary documents raised, etc., etc. This is not difficult, but takes time, and has to involve govt agencies.
So how about it? Why isn’t the government of Cameroon interested?
