Due to insufficient data, it is currently impossible to carry out a final evaluation of the size and distribution of profits in terms of business and economics which have been achieved by cultivating transgenic plants in developing and emerging countries. Studies which claim to be able to do this are not backed up scientifically and are based on unstable projections. Even the case studies from China and Brazil could not improve this situation: The studies published to date on the economic results of Bt cotton cultivation in China are, for instance, based on the data from just a few years and just a few hundred hectares (out of an overall acreage of 5.5 million hectares) and demonstrate enormous fluctuations; for Brazil, no publications at all exist on the cultivation results, only estimations.
