The second instalment of the BBC’s excellent programme on nuts in Brazil, which I blogged about earlier, is online here. There’s also a short article here.
Nuts
I just heard a programme on the BBC World Service in the One Planet series called “Nuts.” It looked at the problems encountered in developing the Brazil nut as a source of income for poor Amazonian farmers. Unfortunately, it appears that some very tight – some would say unreasonably tight – EU regulations about levels of aflavotoxins are preventing exports. There’s part two next week. The website for the One Planet series is here, but this particular programme does not seem to be online yet. I’ll keep looking out for it. Coincidentally, WWF also has a long piece on the Brazil nut out today, which you can find here. International Trade Forum had a piece on Brazil nuts here in 2004.
Silk-making in Kenya
The Sunday Nation has a feature article in its Lifestyle section on silk making in the semi-arid district of Mwingi in Kenya. Apparently, the silk worm used is a hybrid of the wild species found in the area and the domestic strain. People collect eggs in the bush and rear them in mosquito net cages. When it comes time to harvest the cocoons, some of the pupae are allowed to mature and fly back to the acacia bushes. The Commercial Insect Programme of the International Centre for Insect Physiology and Ecology (ICIPE) has helped a local womens’ group establish the first silk processing factory in the region. According to the article, a different race of the wild silk moth is being evaluated in Pokot and other highland areas for the production of tussar or kosa silk. This is a much prized form of naturally coloured silk produced from cocoons from which the moth has emerged naturally in the wild. Fascinating business.
Cocoa: sustainable solutions
CIRAD, the French agriculture research organisation, reports on efforts to make cocoa a more sustainable crop. Using a network that spanned 35 institutes in five African countries, the researchers studied cropping systems, participatory breeding (especially for pest and disease resistance), soil fertility and plant health. Results appear to be encouraging, especially growing the cocoa trees under a shade canopy and interplanting with other high-value crops. Both techniques improve local biodiversity and give farmers additional sources of income.
Biofuel bonanza under the microscope
While I prepare to toss part two of my own humble contribution onto the biofuel bonfire, pop on over to Biopact for a long analysis of Grist magazine’s recent series on biofuels. Biopact does a decent job of expanding Grist’s debate beyond North America. The whole “debate” seems to be doing a better job of generating hot air than biofuels at the moment, but out of this, I hope, only good can eventually emerge. Biofuel from biomass is not a panacea, but if sensibly embraced the idea could bring multiple benefits.
