I’ve lost track of the number of articles like this one I’ve seen over the years; a guide to the wealth of edible species out there in some part of the world, this time the Bong State recreation Area in Wisconsin, USA. Do they raise awareness of diversity in either agriculture or the diet? No idea, but they are fun to do, fun to write about, and in this case even fun to read.
Idaho farmers discover green manure
Members of the Blackfoot people in the state of Idaho have pioneered the use of oriental mustard as a green manure, growing it on potato fields to combat weeds, erosion and pests and diseases. Now a trial with the University of Idaho is extending the opportunity to mainstream farmers in the potato state. John Taberna, a Blackfoot seed distributor, says that oriental mustard (possibly Brassica juncea, but the article doesn’t say and I’m just guessing) has a fungicidal effect, in addition to other benefits of green manures. The tribe’s business council agreed to reduce pesticide use by 15% over the next 20 years, and the green manure is part of that effort.
Urbi et orbi
The latest issue of CTA’s wonderful ICT Update is all about urban agriculture, and has a couple of examples of the application of GIS. I’ve always wondered whether urban areas act as “magnets” for PGR, people bringing their crops and varieties along when they migrate to the city and growing them in micro-environments, and/or as “winnowers” of the varieties available in the immediate vicinity, urban dwellers mostly focusing on the convenient and commercial. We even did an inconclusive study on sweet potato in Nairobi trying to look at this. Is genetic diversity much considered in urban agriculture circles?
Underutilized biotechnologies?
The International Centre for Underutilized Crops (ICUC) has a position paper on the use of biotechnology to promote and develop neglected and underutilized species. You can download it here. The study concludes that some biotechnologies, eg tissue culture and microproagation, have proved effective in enhancing the use of neglected species, but that others, eg DNA fingerprinting for genetic diversity studies, have resulted in only limited practical benefits. The risks associated with applying biotechnologies include centralization, intellectual property protection and the formation of genetic bottlenecks.
When added value loses value
There’s a conflict between helping farmers to get more value from niche varieties or neglected species and ensuring that the market does not become oversupplied as a result of others emulating that success. BBC News reports on the plight of vanilla growers in the Comoros Islands as the rest of the world cashes in on high vanilla prices.
