That other groundnut

This article in African News Dimension sings the praises of Bambara groundnut (Vigna subterranea), saying it could be grown and consumed a lot more in Malawi. Interestingly, one of the reasons why it is underutilized may be customs such as the one which says that only grandparents and widows are allowed to grow it.

Selling African leafy vegetables

Not for the first time, a study suggests that indigenous and scientific knowledge can add value to each other. This one comes from South Africa’s Human Science Research Council (scroll down to p.14 of the pdf). It found that any interventions to assist small scale farmers in the study area — two districts in Limpopo — would have to be low-cost and based on locally available resources and technologies. One of these resources turns out to be local leafy vegetables. The survey found that almost all respondents consumed African leafy vegetables, and dried and stored their leaves for use during the dry winter. It suggested that the communities could generate significant income by marketing this produce more widely.

New medicinal plants

Speaking of medicinal plants, a remarkable study in Peru traces the traditional use of plants for all kinds of curative purposes from colonial times to the present. There’s an article on the work on SciDev.Net here but it is in Spanish. Although many plants used in colonial times have disappeared from the area of the study, traditional healers have replaced them with other species and have thus maintained their pharmacopeia. This is very much a living, evolving tradition.

Lupins against hunger

Bread enriched with lupin flour left people feeling fuller than ordinary wheat bread, according to a recent report. This could be good news for people who would otherwise be taking anti-obesity pills, and even better news for Australia’s lupin farmers. That’s where the research was carried out. I didn’t know that lupin is already widely used in baked goods because it can replace (more expensive?) eggs and butter. Edible lupins are a common snack in Italy. They also periodically crop up as “neglected” species that could solve world hunger given half a chance. Whether this latest news will reinvigorate that effort is anybody’s guess.

Thanking the cranberry

Cultivating cranberries (Vaccinium spp) is pretty weird, involving as it does constructing beds by scraping off the topsoil and replacing it with sand, building dykes around them, and then flooding them at harvest time to collect the floating berries after threshing the vines. The crop is always in the news around this time of year because it is an important item on the menu of the Thanksgiving meal in the US, as a tangy accompaniment to roast turkey. Which is why the National Geographic website has posted this great video about the harvesting process.
