Ask anyone working in plant genetic resources for an example of the importance of growing genetically diverse crops and chances are that sooner or later they’ll mention the Irish potato famine, caused by the late blight fungus Phytophtora infestans in the 1840s. But for such an important – and iconic – disease, it is amazing how what we think we know about it keeps changing. There’s been a re-think recently about which strain of the fungus actually caused the outbreak in Ireland. And now there’s DNA work to figure out where the pathogen came from. The debate on that point seems now to have been decided in favour of the Andes.
Seeds shared and saved
“When you save your own seeds, you can pick from the best plants and produce varieties that work well on your land,” he says. “You can maintain the background of genetic diversity, while adapting it to what works best for you.”
Own up, you thought that was a quote from an admittedly articulate local farmer sharing indigenous knowledge, didn’t you? Well, it was, except that this farmer has a PhD and farms in North Carolina in the US. Heritage and heirloom seeds are a big and growing deal over there, and this article in The Independent Weekly is a good account of the whys and wherefores of seed saving and sharing in industrialized countries.
Pigs stick it to farmer
Even dedicated diversity seekers need a laugh from time to time — which I got from this blog post detailed the birth of a litter of barbed piglets.
Ethiopian herbs promoted
The Ethiopian Biodiversity Conservation Institute has reported on a variety of efforts to conserve and make better use of medicinal plants. Lots of interesting snippets of information, and some ideas others may find worthwhile. Head on over to AllAfrica.com for the story. The Institute has a web site here, with medicinal plants here. There’s also one for the Institute of Biodiversity Conservation and Research. I can’t figure out the relationship between the two.
Farming in the rainforest can preserve biodiversity
Mongabay writes about a newly published study of cacao farming in Indonesia. The bottom line seems to be that while clearing the forest is more profitable, at least short term, growing cacao under a thinned canopy maintains the diversity of wild species and reduces environmental impacts. But some economic incentive may be needed to promote this option over clear-felling. That option, they note, could be premium priced shade-grown chocolate, just like premium coffee.
