Pirates of Lake Victoria

I mentioned a few days ago that the water hyacinth is making a comeback on Lake Victoria, after being almost eradicated by biological control. That’s sparked a small-scale furniture-making industry, but is obviously bad news for fishermen, who are forced to venture further out into the lake to get good catches. That’s far more than just a nuisance, according to an article in The Nation today. The further you go out from shore, it seems, the greater the danger of falling foul of pirates! The veritable heart of darkness that is the nile perch fishery on Lake Victoria is the subject of a very well-reviewed documentary, “Darwin’s Nightmare,” which I hope to see soon. Have you?

More tea, vicar?

You may remember an earlier – somewhat facetious – post on a possible threat to tea diversity in China. Now, from CropBiotech Update, there’s a summary of a far from facetious review paper on tea breeding in that country. Turns out that the China National Germplasm Tea Repositories can count on some 3000 tea germplasm accessions, and that over 200 improved varieties have been released. Some quite advanced biotechnological approaches are being used to speed up breeding. One of the things the researchers are looking at is developing cultivars with low or no caffeine, using RNAi. Personally, I think caffeine-free tea and coffee, like alcohol-free beer, are a bit like a one-legged man at a butt-kicking contest: useless. But the technology is cool.

Chocolate from tree to cup

In honour of Valentine’s Day, albeit a day late, a chocolate-flavoured post today. First, from the great Howstuffworks, How Chocolate Works. Then, ever wondered where you can get the best hot chocolate in New York or Paris? Well, wonder no longer, and check this out. And finally, news that a network has been established to conserve cacao diversity. You can read the Bioversity International press release here.

Brazil to market biodiversity

Under an Environment Ministry initiative in Brazil research groups have selected 775 species to encourage production and hopefully develop major markets. Read about it here:

Five books will be published this year, each dedicated to one of the five major regions of Brazil, containing the knowledge that has been accumulated about these “plants of the future”. Seminars for the business community will be held to spread the word about the potential of these plants, which are ornamental or used to produce foods, beverages, medicines, oils and perfumes.

Olive oil spreads

There’s increasing recognition around the world that olive oil, as a key component of the so-called Mediterranean diet, is really good for you. The latest news is about its effect on ulcers. So obviously the traditional growing countries are trying to expand cultivation and production. But as this article points out, that’s not always so easy. Pity there’s nothing in the piece on varieties, though.
