  • DNA survey of African village dogs reveals as much diversity as in East Asian village dogs, undermines current ideas about where domestication took place.
  • Fossil doubles age of dog domestication.
  • “When children felt like buying candy, they ran into their father’s fields and returned with a few grams of opium folded inside a leaf.”
  • “The rice, a traditional variety called kintoman, came from my grandfather’s farm. It had an inviting aroma, tasty, puffy and sweet. Unfortunately, it is rarely planted today.”
  • “An era of synthetic gums ushered in the near death of their profession, and there are only a handful of men that still make a living by passing their days in the jungle collecting chicle latex…The generational changes in this boom-and-bust lifestyle reflect a pattern that has occurred with numerous extractive economies…”
  • Morocco markets prickly pear cactus products.
  • TreeAid says that sustainable agriculture depends on, well, trees.

Traditional tattoo dye to go mainstream

The report in FoodNavigator seemed pretty boring at first sight:

EcoFlora has developed a natural, acid-stable blue coloring for foods, beverages and cosmetics and it says the creation of a sustainable supply chain differentiates it from other colors on the market.

But then I googled the plant involved (“edible jagua fruit, which grows in the Chocó rainforest” of Colombia). It turns out jagua is Genipa americana, which is cultivated for its edible fruit, but also has other traditional uses.

South American Indians bathe their legs in the clear liquid obtained from the fruit. The liquid has an astringent effect. When the liquid oxidizes, it stains the skin black. These stains are permanent, but only color the top few layers of skin, and thus disappear after about a fortnight, when the skin is naturally shed. As South Americans Indians went into battle, they used to paint themselves with Genipa juice and annatto.

The active compound is called genipin. Apparently, there’s been a “recent explosion in the popularity of Jagua body art.”

There’s nothing in the FoodNavigator piece about where the idea for this “natural, acid-stable blue coloring for foods, beverages and cosmetics” ultimately came from. However…

EcoFlora says it is committed to working with some of the poorest communities in the region to harvest the fruit in a manner which is environmentally sustainable and beneficial to the local economy.

Well, that’s something, I suppose.

Japanese agrobiodiversity art

Adam at Mutantfrog Travelogue, which seems to be a blog about things Japanese, has a post about a craft called Mizuhiki (水引). This involves the decorative use of twine made from a special kind of traditionally-produced paper called Washi or Wagami (和紙). Washi is made from all kinds of different agrobiodiversity:

Washi is commonly made using fibers from the bark of the gampi tree, the mitsumata shrub (Edgeworthia papyrifera), or the paper mulberry, but also can be made using bamboo, hemp, rice, and wheat.

That “gampi tree” gave me a bit of trouble, but I finally ran it to ground. It seems to be Wikstroemia sikokiana in the Thymelaeaceae. The paper looks beautiful. Anyway, in researching all this I came across a little gem:

In 1869 the then Prime Minister, William Gladstone, requested a report on Japanese paper and papermaking from the British Embassy in Japan. A thorough investigation was carried out by Sir Harry Parkes and his team of consular staff in different Japanese towns, resulting in the publication of a government report, “Reports on the manufacture of paper in Japan“, and the formation of a collection of 400+ sheets of handmade paper. The main parts of this collection are now housed in the Paper Conservation Laboratory of the Victoria and Albert Museum, and the Economic Botany Collection of the Royal Botanic Gardens, Kew. In 1879 Kew sent duplicate samples to Glasgow, Sydney, Melbourne and Adelaide, but these have been lost. The Parkes paper collection is important because the origin, price, manufacturing method and function of each paper was precisely documented.

Something to check out the next time I’m in London.
