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…
Mexico atlas
If you’ve been reading this blog for any length of time you’ll know I have a thing about agricultural atlases. Well, here’s another one. Mexico’s Instituto de Geografia has put its Atlas Nacional de Mexico online, and it includes maps of crop production such as these (dating back to 1989, though). However, these are just high definition scans rather than real digital maps, which makes them slow to load and difficult to use. But beautiful to look at.
Buzz on GM crops and bees
We’ve written a bit here about pollinator problems. The looming shortage of bees in the US, and in Spain. We pointed to a piece that said maybe the problems in the US weren’t any worse than they had been, just better reported. Maybe the problem is monoculture? Throughout the recent buzz of hive-related news, though, we’ve ignored a few items that laid the blame on GMO crops. Why? Because they seemed a bit shrill, maybe even a tad one-sided. But a long and apparently comprehensive piece in the German news magazine Der Spiegel is neither shrill nor one-sided. And it seems to adduce good evidence that bees who are suffering a parasite infestation are abnormally susceptible to pollen from maize engineered to express the Bt bacterial toxin from Bacillus thuringiensis.
The work Der Spiegel reports is a long way from conclusive. But it does give pause for thought, and it is causing huge excitement among opponents of GM in all its forms. At the very least, it deserves a closer look. But wouldn’t it be weird if it proved true? And how would industrial agriculture respond?
Of dung, mites and llamas
Researchers are counting fossilized dung-eating mites in the sediments of an Andean lake to get an idea of the size of llama herds in the surroundings, and thus “reconstruct the fluctuating fortunes of local (human) populations for an era from which no written records exist.” It turns out that “mite numbers rise and fall in concert with well-documented socio-economic changes in the postconquest period.” The paper is in the Journal of Archaeological Science, but you can read a summary here.
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.
