A long piece on Philippine agricultural biodiversity and agroforestry in a blog called MagSakaUnlad, written by Virgilio Villancio, who is with the Agricultural Systems Cluster of the College of Agriculture, University of the Philippines at Los Banos.
The perils of rarity
It stands to reason that as the cost of finding and an over-harvested medicinal plant, say, increases beyond the market value of the product, people will stop looking for it, hopefully giving the population a chance to recover. Well, yes, but what if the very increasing rarity of the plant – or animal – actually in turn ratchets up its value? The result is a positive feedback loop which can only end in extinction. Or so says a mathematical model described in Nature, backed up by some telling examples. So publicizing the fact that a species may be rare and threatened (for example, in a Red Data List) may actually make things worse! Taking species into cultivation may be one way around the problem.
Rescuing food traditions around the world
Renewing America’s Food Traditions (RAFT) “is a coalition of seven of the most prominent non-profit food, agriculture, conservation, and educational organizations dedicated to rescuing America’s diverse foods and food traditions.” You can download here their great book explaining what these traditions are. There’s also a map of North America’s “totem foods.”
Same topic, different region: Dr Lois Englberger of the Island Food Community of Pohnpei (right, with some of her NGO’s information products) has made Pacific Magazine’s list of “293 Pacific Leaders You Need To Know” because of her efforts to promote local island foods, food crops and food traditions. Congratulations, Lois, and keep up the good work!
Tea threatened?
Will the disappearance of the traditional Chinese tea-house lead to a decline in tea diversity? I’m not sure to what extent the diversity of teas we see in supermarkets and specialty shops is due to differences in provenance and processing as opposed to genetic differences among cultivars. No doubt a bit of both.

Let them eat sorghum
The Prime Minister, no less, has told Tanzanian farmers to grow sorghum rather than maize, where appropriate, because maize “does not enhance their economic status”, according to a report in The Daily News. Mr Lowassa pushed millet and cowpeas too. He also expressed indignation at the way farmers were recklessly cutting down trees and allowing cattle to graze close to water sources.
