摘要：The Green Revolution can be seen as a technological paradigm originated from developments in chemistry and biology, determining a technological path of extensive use of chemical inputs (fertilizers and pesticides). Since the 1970’s, the limits of the Revolution have become apparent, especially with the identification of environmental problems caused by chemical residues and the growth limits of the chemicals industry. Developments in biotechnology have led to techniques that overcome genetic barriers found by traditional techniques. If, on the one hand, such change has led us beyond the limits of the Green Revolution, on the other hand it allowed the diversification of firms in the chemicals industry. The point discussed here is whether this new technology will reduce the use of chemical inputs or simply resume the old paradigm with new tools, under an industry strategy of increasing the value of its assets.
