For the commercial grower, the concept of seed saving is probably something of a luxury. For the kitchen gardener it is about as satisfying as it gets, bringing the full cycle full circle. It is not, however, a luxury in subsistence farming in developing countries around the world, where small scale farmers feed their families and their communities using seeds harvested from previous seasons' crops. (Indeed, it maybe something we return to in the 'developed' West/North one day - but that's another story.)
Seed saving as a hobby is one thing. Seed saving as a means to having food on the table is quite another. Farmers in poorer countries often depend on saving, sharing and swapping seeds that have been developed over generations to thrive in local soils and climates. Their harvests are more successful, they require no cash, and they can sell any surplus through local markets.
GM seeds with a 'suicide' gene have been developed by the big Biotech Boys. These seeds are created to produce just one harvest. This means that you have to come back to buy more the following season, every season. What's more, the seeds are designed to be used with chemical fertilisers and pesticides (supplied by the same Biotech company, funnily enough). With cross contamination impossible to stop, all it takes is one farmer to grow the seed, and the genes can intermingle with neighbouring farms, rendering their seeds sterile too.
Progress? The technology is not currently commercially available, in part due to the avalanche of opposition in support of rural communities in the developing world. However, knowledge of this technology is useful in conveying the sheer brutality of the GM industry to the uninitiated, and to undercut the Biotech PR machine that claims it aims to help the poorest farmers in the poorest countries.
An eloquent discussion on the politics of seed saving is worth a read in Vandana Shiva's article
"The Suicide Economy of Corporate Globalisation". For the latest news on GM, visit Michael O'Callaghan's comprehensive
