Here’s a turn-up for the books. Our friends at the CAS-IP blog link to a couple of papers that examine the influence of intellectual property rights on vegetable diversity. I’m going to come right out and admit that I haven’t read the papers. But like CAS-IP, I’m intrigued by this quote:
More than 16% of all vegetable varieties that have ever been patented were commercially available in 2004.
Or, to put it another way, less than 84% of all vegetable varieties that have ever been patented were no longer available in 2004.
The primary argument for maintaining crop diversity ((I’m not sure that that would be my primary argument, but let that be.)) is based on the need to maintain a safety net of genetic diversity, to have a broad supply of genes available to breeders who can create more productive, weather-hardy, insect resistant, fungus resistant, and better-tasting crops. … If the meaning of diversity is linked to the survival of ancient varieties, then the lessons of the twentieth century are grim. If it refers instead to the multiplicity of present choices available to breeders, then the story is more hopeful.
The crucial part, of course, is how to measure diversity, and how you interpret it. I deliberately snipped out what I consider the money quote from the passage above. Here it is:
We hope our findings stimulate a discussion about the proper measure for that diversity.
Off you go. Discuss away.
