Yes, the food crisis is indeed a very serious issue. I think we should remember that there are currently no GMOs designed specifically, in terms of gene transfer, to increase yield. Most of it is herbicide resistance or produces pesticides. I think that's the reality of this.
Secondly, all the international NGOs who have been in the field in the south working on those issues will tell you that sometimes the very little answers can have the best impact. It's not necessarily putting new technology on the market. Several years ago an international organization of the UN did an extensive report, which looked at solutions adapted continent to continent. In most cases, GMOs were not the key elements to address and solve the food crisis.
