If it should work, that is. I still haven't seen evidence of the technology actually working.
But from my understanding through working with governments and farmers in the south, there is a concern of loss of farmers' seeds and varieties and biodiversity. In two respects, there is a worry. One is the implications for health, because we also require a certain diversity in order to cover nutritional needs, but also in terms of farmers, that they can have their livelihoods.
My concern would be if seeds were only produced for sale, to give to farmers from the perspective of financial gain. If that was the only motivation to breed seeds, that would worry me. For example, IRRI or other institutes will actually research and produce seeds really with the needs of farmers in mind; they're not concerned with sales.
I feel this is something that really will need looking at, but that would exactly be the socio-economic implications that are required to be looked at by the CBD. But that is not my expertise, so I'll have to pass on that.
