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.
