International Day for Biodiversity in Nairobi

If you’re in Nairobi, Kenya, next Saturday 22 May and you feel like celebrating the UN’s International Day for Biodiversity in this, the UN’s International Year for Biodiversity, you could do worse than pop along to the National Museum of Kenya’s Louis Leakey Auditorium for the first Nairobi Agrobiodiversity Debate. Kick off is at 11.30 a.m., and this is what you can expect, according to the organizer’s website:

Hans R Herren, an internationally recognized scientist and current president of the Millennium Institute (Washington, D.C., USA), will be the key note speaker. Hans’s fellow panelists will include Professor Steven Gichuki, Dean, School of Environmental Studies Kenyatta University and Patrick Maundu, an Ethnobotanist with National Museums of Kenya and Honorary Research Fellow with Bioversity International (Kenya and Dr Balakhrishna Pisupati from UNEP along with a few more special guests. The Nairobi Agrobiodiversity Debates will be moderated by our very own Dr Toby Hodgkin, Coordinator of the Platform for Agrobiodiversity Research and Principal Scientist with Bioversity International (Italy).

We’ll gratefully accept any first-hand reports.

Deconstructing the spread of agriculture

Did agriculture move in the hands of people, or with the words of people? Or, somewhat more prosaically:

Two alternative models have been proposed to explain the spread of agriculture in Europe during the Neolithic period. The demic diffusion model postulates the spreading of farmers from the Middle East along a Southeast to Northeast axis. Conversely, the cultural diffusion model assumes transmission of agricultural techniques without substantial movements of people.

Actually not just Europe. And the jury is still out. Two recent paper both tilt towards cultural diffusion, both in Europe (which is where the above quote comes from; but not everybody agrees) and Island SE Asia. This sort of work is mainly done by anthropologists and human geneticists. Sometimes the genetics of livestock or crops are brought into play, but only rarely both at the same time. A grand synthesis of human, livestock and crop genetic data, archaeology and anthropology remains to be done…

San Francisco apes Svalbard global seed vault — locally

In our line of work it is common to hear people rave about the importance of informal seed systems for ensuring that farmers have access to the agricultural biodiversity they need and want — in developing countries. Not so common elsewhere. Now, from the Ethicurean, comes news of a project to build a Backyard Seed Vault, which sounds very like an informal seed system in San Francisco, California. The project’s instigator, who is co-executive director of a group called Agrariana (and check out their origins and mission statement), has this to say:

We’re looking for approximately 100 San Francisco Bay Area gardeners for the inaugural season who would like to work as a community to save heirloom vegetable seed. … Agrariana will lead hands-on workshops in participants’ gardens on properly saving seed. The Backyard Seed Vault is working in conjunction with the Bay Area Seed Interchange Library (BASIL), a project of the Ecology Center, for their immense knowledge on properly saving, labeling, cataloging, and storing seeds. Seeds not redistributed to participants will be donated to BASIL, providing an opportunity for any community member to “check out” seed to grow in their gardens. Gardeners of all skill levels are welcome to participate.

Sounds like a lot of fun. And there are actually lots of similar seed exchanges all over Europe, North America, Australia etc etc. Will they, I wonder, ever attract the attention of people who study the value of informal seed networks elsewhere?
