Avocado domestication and iconography

I took advantage of the thirteen hour flight to Lima to catch up on some reading, including a recent paper reviewing the state of knowledge on avocado diversity and domestication. ((Mari­a Elena Galindo-Tovar, Nisao Ogata-Aguilar and Amaury M. Arzate-Fernandez (2008) Some aspects of avocado (Persea americana Mill.) diversity and domestication in Mesoamerica. Genetic Resources and Crop Evolution 55:441-450. http://dx.doi.org/10.1007/s10722-007-9250-5.)) The authors postulate that avocado exploitation began in Central Mexico with the gathering of fruits from the forest, possibly as long ago as 8000 BC. Then, when the climate changed for the worse around 4500-2000 BC, people began to tend and cultivate the tree in forest gardens. The final phase was one of intensive cultivation in homegardens and active dispersal around the region and into South America.

That’s all very interesting, but the thing that really stuck with me was the observation that the avocado tree is represented on Hanab-Pahal’s sarcophagus from Palenque. Not on the famous “astronaut” lid, however, but on its side. Ten ancestors are seen around the sides of the sarcophagus, arising from a crack in the earth, each with a fruit tree, forming a sort of homegarden around the dead king. Among them is Lady Olnal, and she has an avocado tree. Unfortunately, I couldn’t find a picture of this on the internet. But the reason it struck me is that I’d just been looking at photos of more recent, and geographically somewhat distant, but no less botanical, funerary art. Even in death, people of all ages and cultures like to be surrounded by plants, it seems.

And, being in Peru, all this rumination about art and agrobiodiversity couldn’t help but remind me of Marcos Zapata’s painting of the Last Supper in Cuzco Cathedral (1753). That famously features roast cuy, but check out the thing to the left of the cuy’s head. Is it a maca? What other crops can you identify? Donwload the full-sized version on the photo and see. No avocados, alas.

Yams in New Caledonia

Danny has just sent me this great old postcard from New Caledonia: “Preparations for a family celebration.” You can see how central yams are to Kanak culture. In 2004 the Kanak Traditional Senate established a Conservatoire de l’Igname. I never visited it, but I saw photos of it when a couple of the people responsible, including a senator, came to our regional plant genetic resources network meeting in Fiji a couple of years ago, and it looked great. Unfortunately, it doesn’t seem to have much of an online presence.  Yet.

Momi-2008

The latest of Mitsuaki Tanabe’s monuments to wild rice was unveiled in the FAO building in Rome yesterday. Tanabe has donated this sculpture to the Global Crop Diversity Trust, and it is now installed by a window just in front of the Trust’s offices. Representing a seed of Oryza meridionalis, which is found in northern Australia, “Momi-2008” is about 9 m long and about 250 kg in weight. It took 20 men to get it up the stairs. This photo doesn’t really do it justice.

African protected areas surveyed

The EU-funded “Assessment of African Protected Areas” is out:

The purpose of the work is to provide to decision makers a regularly updated tool to assess the state of Africa PAs and to prioritize them according to biodiversity values and threats so as to support decision making and fund allocation processes.

It is great stuff: detailed, standardized descriptions of the importance of — and threats faced by — each protected area in Africa. I wonder if something similar will ever be done for agricultural biodiversity. An interesting first step might be to mash these results with those of the recent survey of crop wild relatives in protected areas. Unfortunately, the agrobiodiversity and protected areas communities hardly ever speak to each other.
