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…
