This would be a tremendous benefit for poor farmers. But unless this technology is cheap or freely available, it seems very unlikely that the people who need it most would ever have access. These are seeds that die after one year so that farmers cannot save the seed and use it again. Biotechnology is not currently a necessary precondition for feeding the world. However, it is fair to say that improvements to farming will arise from genetic engineering if the research is public-funded and for the public good.
Biotechnology is therefore unlikely to benefit the poor in the short term.
The answer to this question is simple - farmers in those countries, using sustainable methods of production. Sustainable agriculture - the quiet revolution has started Quietly, slowly and very significantly, sustainable agriculture is sweeping the farming systems of the world. It does this by integrating natural processes such as nutrient cycling, nitrogen fixation, soil regeneration and pest predators into food production processes. And third, it makes better use of the knowledge and skills of farmers, so improving their self-reliance and capacities. During this century, modern agriculture has seen external inputs of pesticides, inorganic fertiliser, animal feedstuffs, energy, and machinery become the primary means to increase food production.
