Indian potato growers are turning to a new, low-sugar variety of potato because it is better for making chips (crisps if you’re British), for which there is rapidly increasing demand. Would be interesting to monitor the effect on “local” varieties, no?
Local and exotic crops in Africa
The long dry spell throughout much of February and March, caused by an unexpected El Nino that kept the main rain belt to the north of Zimbabwe, will cause serious hardship in significant areas of the country.
That’s not the only thing, of course, but an article from the Harare Herald ((Posted at allAfrica.com)) makes a plea for farmers to grow local indigenous grains such as “sorghum, mhunga and rapoko” rather than watch maize “wilt and die four years out of five”.
It is a wonderful article, making lots of good points. That food-for-work programmes should be accompanied by intensive training on growing small grains, so that those who need it most can become self-reliant in food and maybe even sell a bit for income. That modern machinery makes preparation much easier, and it isn’t expensive. That an advertising campaign could make a virtue of sadza ((Zimbabwean porridge?)) the way grandmothers made it. That there are benefits for urban consumers too. And finally, “Variety is wonderful. But we should not be rejecting indigenous grains simply because they are not “modern” or “Western”. We should be using them as well”.
I wonder whether anyone is listening?
The Ethiopian Herald, meanwhile, says green gram is becoming the crop of choice in Southern Wollo zone. A legume, green gram (Vigna radiata, maybe most familiar in the West as mung bean) improves soil fertility, ripens more rapidly and doubles or even triples incomes. One farmer is quoted as having replaced his teff crop with green gram, but if everybody does that, who is going to supply the teff flour for njera?
School gardens
It seems pretty obvious that school food gardens should be quite useful teaching tools. Kids like nothing better than getting down and dirty. Well, anyway, now there’s proof. A paper in the Journal of the American Dietetic Association, whose abstract you can read here, confirms “the efficacy of using garden-based nutrition education to increase adolescents’ consumption of fruits and vegetables.” What an opportunity for also teaching about agricultural biodiversity, highlighting its link to nutrition! Of course, in some parts of the world school gardens actually provide a significant proportion of the students’ diet…
Child malnutrition in Uganda
Some clues in a newspaper article that is unfortunately not online led me to a East African Journal of Medicine paper on levels of malnutrition in a Ugandan village. The researchers found that “young children in Kabarole district suffer from severe chronic malnutrition rates, but rates and feeding patterns are not different in AIDS affected versus non AIDS affected homes.” This last finding may be because children also benefit from the attempts of care-givers to improve the nutrition of AIDS sufferers in the family. Here’s a key recommendation:
Poverty plays a key role in this situation, but there are cost-effective interventions locally available to reduce chronic malnutrition in children. It may require shifting food production to more nutritious foods and foods that are new for this area such as orange fleshed sweet potatoes with higher energy density and protein rich beans.
Sounds like a place where CIP’s VITAA Project could do some good.
Good ethnobotanists have healthier children
A study of the Tsimane, an indigenous group of foragers and farmers inhabiting a remote area of the Amazon lowlands of Bolivia, has determined that mothers who are more knowledgeable about plants and their uses tend to have healthier children. According to this summary of the results, Dr Victoria Reyes-GarcÃa, one of the co-authors of the study, pointed out that “globalization threatens this knowledge to the extent that formal schooling and jobs in emerging markets devalue folk knowledge and provide access to products not made from local resources, but without providing adequate medical treatment substitutes.” I’ll have to find the original paper, because what the summary doesn’t say, and which it would be great to know, is whether better ethnobotanical knowledge translated into more diverse family gardens and more diverse diets.
