Aid Tree Aid

A BBC story alerted me yesterday to the existence of Tree Aid:

TREE AID was established as a charity in 1987 by a group of foresters in response to the famine in Africa, brought to public attention by Band Aid and Live Aid.

They wanted to provide a long term solution once the emergency relief efforts ended. They believed that trees could significantly reduce the vulnerability of communities in rural Africa’s drylands to drought and famine in the future.

Our current strategy expands on the original concept, focusing on forest management and income, food and medicines from trees.

I like their Cake Taste initiative, and their Tree of the Month feature. Seems very worthy. And it’s easy to donate online, should you feel so inclined.

The pedigree of tolerance to submergence in rice

You may remember a post a few days ago about submergence-tolerant rice. Our friends at IRRI have been kind enough to explain to me where the gene in question — sub1 — came from.

I hope I get this right. It seems the immediate parent for IR64-sub1 was from the cross IR49830, which in turn came from the cross IR22385, made in 1978. The source of the gene at the time was a line called FR13A, which was derived from a germplasm accession called IRGC 8887. That was acquired by IRRI in 1963 from India, but with no further passport data.

If you want to get an impression of the complexity of the pedigrees of modern varieties, below is the one for IR64-sub1, with IRGC 8887 highlighted in yellow, thanks to the pedigree visualization tool that IRRI has been developing (click to enlarge).

It’s a great illustration of the reason for the Multilateral System of access and benefit sharing being put in place by the International Treaty for Plant Genetic Resources for Food and Agriculture. In a bilateral system, such as the one envisaged by the Convention on Biological Diversity, how would you work out the contribution of IRGC 8887 — or indeed any of the other germplasm involved in the pedigree — to the overall success or otherwise of the final product?

Browsing Princeton’s image library

A short note in Global Voices sent me to the Princeton Digital Library of Islamic Manuscripts in search of anything vaguely botanical or agricultural. I found a treatise on botany with charming watercolours of many different plants, some cultivated. Perhaps someone out there who can read classical Arabic can tell us the gist.

Roaming a little further around the Princeton Digital Collections I also came across the Western Americana Photographs Collection, which has some really fascinating stuff. I had no idea that Indians stored acorns in specially constructed caches, for example. But it seems to have been a common practice in the Yosemite Valley.

IUCN assesses threat to mammals

Ethiopia’s Institute of Biodiversity Conservation reminded us today — quoting an IUCN study from last year — that the African Wild Ass (Equus africanus) is critically endangered. Actually the Asiatic Wild Ass is also in trouble. The summary of the findings of the 2008 IUCN Red List of threatened mammals highlights the situation in SE Asia as particularly worrisome. People are clearly going through the data now and pulling out different themes. A few days ago there was an assessment of the state of rabbits, for example. I wonder if we can look forward to an overview of livestock wild relatives?
