Non-wood forest products information

You may remember I blogged recently about a couple of FAO news resources, on plant breeding and on biotechnology. I just want to mention today a third: FAO’s Non-Wood Forest Products Digest, the focus of which is pretty self-explanatory. You can subscribe to it here((FAO’s link is broken.)) (there does not seem to be an RSS feed), thereby joining 1300 other people around the world. The website also has past issues. It comes around by email a couple of times a month, and it has the introductory text of articles, announcements etc., with links to the full pieces.

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.

Trade information by mobile

Between the Common Catalogue on one side and regulations on the entry of new agricultural products on the other, it does sometimes seem like the EU just doesn’t want farmers to grow diverse crops, either within its borders or indeed anywhere else on Earth. Anyway, on the latter issue, maybe one of the answers is for developing world farmers to trade more among themselves. One of the bottlenecks to that, of course, is the availability of price and other information. So it was really interesting to read in The Economist about tradenet, an internet application developed by a software company out of Ghana that enables users to exchange market information, including by SMS text messages. Mobile telephony is of course expanding at tremendous speed in Africa. Tradenet is basically a sort of eBay for agricultural products, where you can put in your bid by cell phone. And more. Listen to this: “we will incorporate the ability to generate digital maps of your country with overlays of pricing for commodities, as well as include key markets in neighboring countries, where you can zoom or pan around vector maps.” Cool or what?

Identifying trees from the air

We received the following request from Carlos E. Gonzalez of the Department of Geography, King’s College London in response to an earlier posting on botanical keys. I hope readers will be able to help him out.

As part of my PhD I have been developing an online taxonomic key for tree identification (higher taxa) on the basis on aerial photography. The taxonomic key uses some aerial photography over the Tiputini Biodiversity Station, and the user answers a series of questions on each crown in order to come to an identification. I am now testing this key in order to understand better (a) its success rate in the identification of trees using a large number of different observers and (b) the patterns of correct and erroneous identifications and implications for the key and for how different observers visualise and separate crown features in imagery. I would be very grateful if you would take a short time to identify 20 trees for me. You can find instructions and access to the key and imagery here. Your computer needs to have a copy of Google Earth version 4, available here. I cannot identify which users have given particular answers but will be able to provide some general feedback to the group of users as a whole. PLEASE ALSO FORWARD TO OTHERS WHO MIGHT CONTRIBUTE. Many thanks! Carlos

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.
