Some research commissioned by the UK's Department for International Development into Terminator and similar technologies has just been put on their website. You can access it via:

The report was written in December 1999. Its full title is: Costs and Benefits to the Livelihoods of the Rural and Urban Poor Arising from the Application of so Called "Terminator Genes" and Similar Technologies in Developing Countries.

The quotes below come from the summary of the report:

 “Use of restriction technologies imply a clear loss of options to the poorest segments of society. These options can be crucial methods for providing assurance against complete crop failure in subsistence societies. There is no clear gain achieved by these poorest elements of societies, to compensate for this loss of options” (page 22)

"”¦  switching from traditional to GURT varieties implies a total loss of the biodiversity found within the traditional variety's gene pool.  This implies a much greater loss of agricultural biodiversity than occurred previously from substitution in the Green Revolution" (page 13)
