Where the rubber hits the road

The rubber tree comes from Brazil, but natural rubber itself mostly comes from SE Asia plantations these days. One of reasons is the leaf blight fungus, but now comes news of resistant varieties. This may herald a resurgence in climate-friendly natural rubber at the expense of the synthetic kind, which is made from oil. But will that positive effect be negated by increased cutting down of the rainforest to establish new plantations in Brazil?

Farmers know best?

A comment on a recent post suggested that one should “start with the assumption that farmers know what is in their best interest.” No doubt that is as true of Indian farmers as the rest of us, but unfortunately in many cases there are other pressures out there that mean that you can’t act on your perceived long-term self-interest, or indeed the information on which you can make that determination is not available or turns out to be faulty. As with the sweetleaf item that started this, we don’t know the full story, so we should be careful not to jump to conclusions, but an article in today’s Hindu newspaper describes a decision by farmers that seems to have gone wrong. Agricultural biodiversity, and its associated knowledge, is an important reason – maybe the most important reason – why unfortunate decisions don’t always result in catastrophe.

Sweetleaf hits India

I’m always somewhat ambivalent about the kind of story I saw today on Kangla Online about how some farmers in Senaputi district in north-eastern India are taking up the cultivation of Stevia. This is a South American herb in the Asteraceae which is widely cultivated around the world as the source of an alternative to artificial sweeteners.

On the one hand, it is always good to see farmers diversifying and experimenting, including with exotic crops. On the other, you wonder whether there isn’t a local – and locally used – species that might have been promoted and commercialized in this way. And will the money farmers raise from Stevia be sufficient to buy them and their families the nutritious food they will no longer be growing on their land?

Cotton genetic resources conserved in Texas

You thought Lubbock, Texas was only famous as the birthplace of Buddy Holly? Think again. It’s a veritable hothouse of cotton genetic resources conservation and use. Not much of what you might call news in the Eurekalert piece, but interesting nonetheless. For example, did you know that there are three international cotton germplasm collections, in Lubbock, France and Uzbekistan? Or that breeders are scouring wild cottons for the genes to make the crop more environmentally friendly?
