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.
Dual-purpose weeds
Two stories today about different ways of looking at the same plant. I was walking along a fairly major road in a suburb of Nairobi this morning and I noticed a “jua kali” artisan selling interesting-looking stuff. “Jua kali” is Kiswahili for “under the sun” and is commonly used hereabouts to refer to the informal sector, because under the sun is where most of them transact their business, as in this case. Anyway, I ended up buying the magazine rack pictured here, for about US$15.
The frame is metal, but the rest is made of a tough-looking fibre I couldn’t place. I asked what it was and was very surprised to hear that it is water hyacinth. That’s a very cool use for a noxious weed, which is again choking up Lake Victoria, after a successful biological control effort. It turns out that making furniture out of the stuff is not all that uncommon.
And here’s the story of the mesquite bush in Kenya, a useful plant in some parts of the world (even used as food in some cultures), but seen as a terrible invasive here, in particular by pastoralists in the drier areas of the country. But I bet people are working on novel, profitable uses. Maybe someone in northern Kenya is already marketing mesquite honey, or carvings made of mesquite wood?
Rapid agrobiodiversity surveys
This SciDevNet piece led me to this Nature article on the theory and practice of the Rapid Biological Inventory, “a quick, intensive taxonomic expedition designed to identify areas of particular biological, geological and cultural significance before development and exploitation take hold.”
Using satellite images, maps and other data, biologists target promising areas and then work with local scientists and students to walk existing and newly cut trails, recording the species they encounter. (…) In parallel with these are social inventories — surveys of the organisational structure of local communities and how they use the forest. The teams work with indigenous groups, government and local conservation organisations to deepen their understanding of the value of the surveyed areas.
I think the concept was pioneered by Conservation International, under the name Rapid Assessment Program, or RAP, but as far as I can see it hasn’t been applied to agricultural biodiversity, at least not explicitly. Seems to me one could come up with a pretty good “rapid agrodiversity assessment” methodology based on standard crop descriptors combined with traditional knowledge, wrapped up in a participatory rural appraisal (PRA) approach. Maybe someone already has?
Sandalwood in danger
For some reason or other, there’s been a lot in the news lately here in Kenya about sandalwood and its over-exploitation. There was a piece in the TV evening news just the other day when a huge consignment of the stuff was found in a warehouse owned by an MP. Now here’s an article from The Nation, reproduced by the excellent allAfrica.com.
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.
