Catching up with some old friends in Nairobi last week I found out that one of them has been involved in preparing a really wonderful “Herbal and Nutritional Guide for Kenyan Families” for an NGO called the Trust for Indigenous Culture and Health. According to its mission statement, TICAH works “to strengthen our understanding of the positive links between cultural belief, practice, and knowledge and the attainment of health.”
Tidings of discomfort and sorrow
Frankincense — traditional gift at this time of the year — is the resin of a tree called Boswellia papryrifera native to the Horn of Africa. Alas, a scientific study in the Journal of Applied Ecology proves that tapping the tree for resin decreases the number of flowers and seeds the tree produces, thus “potentially” harming the regeneration of the frankincense woodlands. Non-tapped trees produce three times more seeds than tapped trees, and those seeds are five times more likely to germinate. The authors say that collectors should make fewer taps per tree and allow long rest periods with no tapping.
Indigenous Vegetable Conference
A large conference on indigenous vegetables and legumes ended last week in Hyderabad, India. A press report gives little detail, but abstracts are available here and one may expect the proceedings to be published.
The conference was organised jointly by The World Vegetable Center, the International Crops Research Institute for Semi-Arid Tropics (ICRISAT), Bioversity International, the International Society for Horticultural Science (ISHS) and the Global Horticulture Initiative.
Biodiverse biofuels
Research at the University of Minnesota suggests that growing diverse mixtures of perennials on relatively poor land in a way that mimics natural grasslands is – surprise! – a better way of producing biofuels than intensive monocultures of maize or soybeans. This will run and run. I bet tinkering with the species composition and perhaps breeding some of the component species will be next, and lead to significant improvements in the system. While we wait for that though, here’s what Grist calls a two-week crash course on biofuels.
An insider’s view of sorghum in India
Prashant Mishra gives an Indian NGO’s perspective on sorghum and why many Indian farmers refer to it as Jowar Mata — Mother Sorghum. Even after the advances of the Green Revolution, sorghum thrives and sustains the very poorest people in marginal lands.
