Yam secrets revealed
I ran across an interesting article in The National newspaper last week in PNG, but I can’t find it online, so I’m posting a scan of it below. You should be able to read it ok if you click on it. It’s worth it. How can anything with the title “Secret Abelam yam initiation exposed” not make for fascinating reading.
The Abelam people are from East Sepik province and their life — especially the life of the men — revolves around yams:
Among the Abelam, the yam cult is a unique cultural institution and the focus of male existence. It involves men striving to produce long tubers (up to a length of 6 feet/180 cm or more), in intense competition with a long term partner in a neighbouring village. There are two major ritual cycles in Abelam life, both centred on this cult — initiation ceremonies which instruct young men in the magic and skills required to grow the prized long yams, and yam growing ceremonies and rituals designed to ensure the success of the current crop.
There are also yam festivals after harvest:
The actual yam displays are very festive occasions. Yam growers from rival villages generally arrive together on the morning of the event. When they are all gathered, the yams, which have been concealed behind barriers and decorated with shell, feather, and basketry ornaments, are carried onto the ceremonial ground. Each waapi is attached to a pole, and carried by two men, one at each end. As the yams are paraded, guests show their approval of their rivals’ efforts by putting special leaves (naarendu) or lime on particularly good specimens. Subsequently the waapi are lined along wooden frames in front of the ceremonial houses where they are carefully inspected and measured by ritual exchange partners. Following the inspection, rivalrous songs, particularly on the themes of yam exchanges and warfare, are sung by individuals. Groups and individuals may claim victory in these song contests by virtue of “evidence” and superior oratory.
It all sounds very spectacular. And extremely important:
…ceremonial yams have an important political function: to a large extent, male status, prestige, and power are dependent on the size and quality of ceremonial yams grown.
In addition to their importance in the political arena, “long yams” have considerable expressive content. Since all yams are propagated vegetatively, yams also form a link between living Abelam men and their ancestors, who planted genetically identical yams. Abelam often invoke their ngwaalndu (clan ancestral spirits) when growing and tending yams. The link between a man, his ceremonial yams, and his ngwaalndu is very close. Yams are of paramount social, symbolic, and religious importance to the Abelam people.
The species involved are Dioscorea alata (waapi) and D. esculenta (jaambe). These are under pressure in some parts of Papua New Guinea, being replaced by recently introduced African species, which seem to withstand pests, diseases and drought somewhat better, I was told. This doesn’t yet seem to be the case for the Abelam, but I wonder for how long. Maybe aeroponics is the answer?
Bananas galore
Rosa would certainly have welcomed a great new ((New to me anyway. It’s dated 2011 but today is the first I heard about it.)) catalogue of some 50 banana varieties from the Solomon Islands by Gabriel Sachter-Smith, put out by ProMusa. The varieties on the cover are Broken Heart, Ruhuvia Chichi and Ba’u Lalao.
Oh, and there’s also a new wild subspecies from India.
Nibbles: Custodian farmers, Farming wild species, Museum of Agriculture, GMO maize in Mexico, Organic metareview, Boron tolerance, Date tomato, Cultivated Plant Taxonomy Newsletter, Barcoding Welsh honey
- First, find your custodian farmers.
- Sure, they can farm wild species too.
- Then, get them to produce something cool, sell it, and use the money to preserve some nearby temples.
- Oh yeah, but better make sure there’s no GMOs around.
- Organic helps. No, really.
- Ok, so maybe you have to help them out by breeding for higher boron tolerance or something.
- Something like tomatoes that don’t rot. And in French, but with photo.
- Make sure the taxonomy is right, though.
- And if in doubt, use barcoding.

- Liquorice next? Starting in the UK?
- India has 30% of the world’s cattle. Which you might not be able to guess from these very cool ILRI maps. Including one on chickens, in which the Nordic countries feature perhaps less than they should.
- The Global Nutrition Report will have these indicators at country level. Some stuff there on fruit and vegetable consumption, but why nothing specifically on dietary diversity? Anyway, if you’d like to make suggestions, you can.
- Wait, why is there nothing on alcohol consumption? And is diversity in alcohol-producing plants a good thing? I mean, nutrition-wise.
- Uhm, nothing on urban agriculture either. I bet you that’s an indicator of something or other, nutrition-wise.
- Maybe Amy Ickowitz of CIFOR will suggest some indicators. She has interesting data on forest cover and child nutrition.
- How to make cacao cultivation more sustainable.
- Andy Jarvis on how to scale up climate-smart agriculture without necessarily sacrificing goats. Nor, presumably, nutrition.
- Model says environment can support subsistence hunting and agriculture only up to a point, and no more. Still no cure for cancer. But did someone tell the Mapuche?
- Well, what do you know, genes come, and genes go.
