A CREDIT paper now out in Food Policy uses some fancy maths to suggest that the health and nutritional status of Rwandese rural people is more dependent on how much beans, sweet potatoes and other crops they produce, rather than on their income. That’s because of “market imperfections,” which is a polite way of saying that there are no markets. A sobering thought for those development agencies which pin all their hopes on the private sector. The author doesn’t discuss this, but I would have thought the dataset is a suitable one to investigate the relationship between dietary diversity (using the proxy of production diversity) and health. Tragically — and actually rather surprisingly — output of local beer has a significant negative effect on nutrition and no effect on health.

Bottled vegetables
After I learned a lot about container gardening from Prof. Dr. Willem Van Cotthem in Belgium, my life has changed for a better, because in otherwise useless plastic bottles and plastic bags I can now grow vegetables to produce food for my family, as well as beautify my home with beautiful flowers. At the same time, I am cleaning the environment around my house.
Read more about how Patrick Harry Dimusa has taken to container gardening in Malawi. And speaking of Prof. Dr. Willem Van Cotthem in Belgium, whom God preserve, I wonder what happened to his open-pollinated melon seed scheme? I know I sent some …
Orange revolution
Sweetpotatoes come in different colors and tastes (and sizes). The “yams” eaten in the United States are sweet and have orange and moist flesh. The staple of parts of Africa and the Pacific (and pig feed in China), is typically white-fleshed and not very sweet nor moist (notwithstanding variations like this purple variety.)
Anyway, the orange fleshed sweetpotato is stacked with beta-carotene, the stuff you need to eat for your body to make vitamin A. Many poor people have vitamin A deficiencies, which leads to stunted growth and blindness. So why don’t the poor sweetpotato eaters eat orange fleshed varieties? In part because they simply do not have them, or know about their health benefits. In part because they do not grow well in Africa (decimated by pests and diseases). And also because they do not taste right: too sweet for a staple.
The International Potato Center and partners have been trying to fix all that. Now they have made a nice video about getting orange-fleshed sweetpotatoes into the food-chain in Mozambique. The orange revolution:

Nibbles: Frogs, Noni, Cassava etc, Commons, Starch, Aurochs, Oats
- Frog porridge.
- Noni in excruciating depth.
- Caribbean seeks food security, turns to “cassava, sweet potato, bananas, yams and many others”.
- Uncommonly interesting article on commons.
- Nice summary of the amylase-gene-copy-number-and-starch-in-the-diet story.
- Dutch aurochs survived longer than thought.
- Yes, we have no oats.
