It seems that capsaicin, the stuff that gives hot peppers their zing, prevents immature fat cells developing into the fully-fledged sort. At least in laboratory experiments – but at levels not unlike those found in the stomachs of people who’ve just eaten a Thai meal. So, rather than jogging today, I’m going for a curry.
Unchaining cassava in Africa
Via “Timbuktu Chronicles,” a fascinating blog by Emeka Okafor about African entrepreneurship and innovation, comes a link of a 2005 Common Fund for Commodities paper on the development of the market for cassava in Africa. The bottom line seems to be that the commodity chain needs to be strengthened and supported by appropriate and sustainable services. Given the cassava boom that has been sweeping Nigeria of late, that may in fact have happened since the paper was written. Other recent entries on Emeka’s blog look at honey and community genebanks. This RSS feed is going straight into my reader.
Breeding orphan crops for Africa
News arrives of a conference on New approaches to plant breeding of orphan crops in Africa. To be held from 19-21 September 2007 in Bern, Switzerland, the conference promises to
“bring together scientists both from developed and developing countries and discuss techniques that could be implemented in a scheme of orphan crops improvement. In addition, future prospects and feasibility of modern biotechnology in African agriculture will be addressed. Success stories will also be presented by prominent scientists.”
All fine and dandy, of course, and we’re looking forward to the results. But we’re impatient. So here’s our offer: if you’re going to the conference, why not become a guest blogger for the occasion?
We’ll supply everything you need — a user identity, a password, even some basic training. All you need is the motivation, the computer, the ticket to Bern etc etc. And in return, we can offer the undying gratitude of lots and lots of readers. How about it? Use the form to contact us, or just send an email.
Vegetable soup as chemical reagent
Here’s one that’s hard to characterize: scientists in the US and Brazil say that common vegetables contain many of the chemicals that chemists need to perform their research, and that scientists in the developing countries, who often lack the funds to buy reagents, should make use of these resources. I’m not competent to judge but the paper, in the Journal of Natural Products, contains a pretty impressive list of things you can make (chemically) from vegetables.
How to halt desertification
IRD in France has released the results of a long study of the Jeffara region of Tunisia, which has been very prone to desertification. The study pinpoints the role of agriculture and the use of natural resources as key factors in the spread of deserts, but acknowledges the very complex interactions at work. The press release concludes:
“[D]egradation can be checked by prohibiting the development of endangered natural environments for cultivation. However, real practical alternatives must in that case be proposed to farmers, in the agriculture sector, through maintenance of a certain diversified production in their holdings and enhancing commercial value of high-quality local or regional produce, but also by means of diversification of activities and of sources of revenue other than farming. This diversification would offer people improved flexibility to face up to climatic and economic hazards and enable them to manage better their families’ financial resources. In addition, the effort government has made in water management, through the CES, could be enhanced by schemes for desalinating brackish water and recycling waste water.”
But can they find a way to diversify and add value before the farmlands, soils and water have vanished completely?
