Sometimes a crop just doesn’t have the genes for it, as a good friend of mine who dabbled in taro breeding used to say. So then you have to try something else. “Zerihun Tadele is using the latest biotechnological methods to produce dwarf tef lines in order to prevent lodging, which causes significant yield losses.” The technique involved is TILLING (Targeting Induced Local Lesions IN Genomes), an automated methods for inducing, and then detecting, potentially useful point mutations. But is there really no short(ish) teff variety among the 4743 accessions in the genebank of Ethiopia’s Institute of Biodiversity Conservation? By the way, IBC has just won the Sultan Qaboos Environmental Preservation Prize. Congratulations!

Surf’s up in Solomons
My friend Tony Jansen and his friend Jon put together this fun video on the Solomon Islands. It’s ostensibly about surfing, but there’s stuff in there about agricultural biodiversity too. I met Tony when he was working at Kastom Gaden Association, a great local NGO working on sustainable agriculture and nutrition issues. We worked together on the livelihoods assessment of the Weather Coast of Guadalcanal.
Aquaculture big in Egypt
I stumbled on a fairly recent (2006) summary of aquaculture in Africa which at first sight suggests an incredibly impressive expansion in the use of aquatic agrobiodiversity — something like a five-fold increase in tonnage in the past ten years or so. ((via Timbuktu Chronicles.)) A closer look, however, shows that most of that increase has occurred in a single country: Egypt accounted for 83% of African aquaculture production in 2004, and 42% of that was Nile tilapia. The industry does seem to be diversifying a bit in terms of species, but not much, judging by the graphs. I hope there isn’t a bust coming after this boom…
