Educated fruit

This story — EARTH University Bananas and Pineapples Arrive in Whole Foods Markets’ Stores in the Southeast — needs a bit of unpacking.

There is an agricultural university in Costa Rica called EARTH; Escuela de Agricultura de la Región Tropical Húmeda. EARTH was founded in 1990 on a former banana plantation, and has its own model banana farm. Also, two pineapple plots. It aims to teach a kind of ethical agriculture. Profits from the sales to Whole Foods Markets support scholarships and research and investment in pineapple production. The Southeast in the story refers to Atlanta, Georgia, USA.

Even though Whole Foods Markets is an 800 lb gorilla, on balance this is probably A Good Thing.

GI had no idea there was so much diversity

We know hardly anything about the differences among varieties of the same crop. Oh sure, we know what different varieties look like; that’s easy. But detailed differences in composition are hard to find. There are the classics, of course, like wetet be gunche sorghum in Ethiopia, whose name translates as “milk in my mouth”. It contains almost a third more protein than other sorghum varieties and, even more important, about double the level of lysine, a vital amino acid for human nutrition. And there are the red and black varieties of rice, which are known to be high in iron and other minerals and vitamins and which are traditionally used to treat anaemia, especially in pregnant women. (I have been unable to discover whether this treatment is effective, in a Western sense, but it seems entirely reasonable, and a bit churlish to deny it.) But in general, we know next to nothing about the nutritional qualities of varieties, as opposed to species.

China to protect biodiversity

China’s new National Strategy for Plant Conservation has just been launched, and Botanic Gardens Conservation International (BGCI) has a write-up about it. An introduction to the strategy is also available. Agricultural biodiversity gets quite a high profile, which is great, and unusual for such exercises. Here’s a few quotes to give you the flavour:

China is home to some of the world’s most important crop, medicinal and ornamental species, such as tea, rice, soy beans, ginseng, magnolias, camellias & peaches.

China is … keen to investigate novel methods of ‘eco-agriculture’, in a bid to introduce more sustainable land management practices to a country which is still largely agricultural.

The system known as the “3R Model” (Resources, Research, and Resolution) has recently produced a unique golden-fleshed kiwi fruit, bred from wild native kiwi vines that were conserved by the project.

A national Chinese seed bank (containing 340,000 accessions) and a network of regional seed banks ensures the long-term conservation of the genes of important crops, such as rice and soya beans.

Over 11,000 species are used in traditional Chinese medicine. Of the 600 plant species that are regularly used, sustainable cultivation systems have been developed for 200 species, thereby preventing their unsustainable harvesting from the wild.

One thing I didn’t understand, though. There’s a picture of a cultivated field in the introduction to the strategy, and also in the BGCI piece, with the following caption:

Fields of cultivated ‘wild’ barley, found only in the Chinese Himalayas, demonstrate the importance of local and ethnic crop varieties.

No doubt there are wild species of Hordeum in the Chinese Himalayas. But what does it mean to say that they are cultivated? Similarly, there is cultivated barley there. But what does it mean to say that it is “wild”?

Youth farmstands in the Garden State

Rutgers University’s New Jersey Agricultural Experiment Station has something called a Youth Farmstand Program. Farmstands — market stalls selling local produce, often organically grown — offer “a hands-on entrepreneurial experience to youth in the mechanics of owning and operating a small business, based on the premise that experience really is the best teacher.” They also provide “a unifying framework for youth, farmers & communities to achieve success. Each needs the others’ support to grow and prosper, so everyone wins!” Sounds like a great idea to promote agricultural biodiversity, better nutrition and youth development all at the same time.
