Training manual for GIS analysis of agrobiodiversity data

Great to see “Training Manual on Spatial Analysis of Plant Diversity and Distribution” finally out, courtesy of Bioversity International. Well worth the wait, and not just because I get called a pioneer in it. Congratulations to Xavier Scheldeman and Maarten van Zonneveld for addressing a very important need.

This manual has been published as a result of the increasing number of requests received by Bioversity International for capacity building on the spatial analysis of biodiversity data. The authors have developed a set of step-by-step instructions, accompanied by a series of analyses, based on free and publically available software: DIVA-GIS, a GIS programme specifically designed to undertake spatial diversity analysis; and Maxent, a species distribution modelling programme. The manual does not aim to illustrate the use of each individual DIVA-GIS and Maxent command/option, but focuses on using GIS tools to help answer common questions relating to the spatial analysis of biodiversity data. Throughout the manual, the importance of proper sampling is stressed; however, it is beyond the scope of the document to elaborate on sampling theories. The manual also does not discuss the statistical analysis of diversity data in detail; instead, when statistical methods and programmes are mentioned in the text, the reader is referred to alternative reference materials for further information.

Promote better nutrition and self-sufficiency with a few clicks

The Cooperative Society in the UK recently launched a scheme called Join the Revolution. People submit projects and other people vote for them. Winners get money — GBP 5000 — towards their project.

A project I already knew about alerted me and asked me to vote, which I have done even though, to be perfectly honest, the proposal didn’t exactly set the heart aflutter. There’s another project in similar vein that is currently doing better, so I won’t link to that, but it isn’t hard to scan all the submissions and pick the revolution you would most like to foment. In fact, you’re allowed to vote for as many as you want, which seems a little odd. On the other hand, having clicked the few times needed to register on the site, it seems wasteful not to vote often.

There are some videos about projects which, I think, were funded in an earlier round. Here’s one I could relate to.

Are there any other Coop-funded revolutions we should promote? Other competitions?

A millet is a millet is a millet. Not

It’s been all over the news 2 that a new hybrid millet from China is going to solve Africa’s food problems. Even our friends at CIAT think so. Nowhere does it say in the endlessly reproduced press release, however, what kind of millet we are talking about. Pearl? Broomcorn? Finger? Foxtail? Proso? 3 What? Intensely annoying. Anyway, cut a long story short, it turns out to be foxtail millet, Setaria italica. We know because the “father of hybrid millet,” Zhao Zhihai, President of the Zhangjiakou Academy of Agricultural Sciences, Hebei visited ICRISAT recently, and the information people there wrote up the visit, and took a photo to immortalize it.

But, as far as I know, foxtail millet is not much grown in Africa, so this statement in the press release is dubious to say the least:

“Millet is staple food in many African countries. The success of the ZHM’s pilot plantation promises good prospects for its mass production in Africa,” said Zhang Zhongjun, assistant to the FAO representative to China.

Pearl millet and finger millet are indeed staple foods in many African countries, but not foxtail of that ilk. Which is not to say that it could not become a staple. After all, it tastes better than teff, which, however, one is bound to point out, is not often called a millet.

“We helped some local farmers to grow the hybrid millet and promised to buy their harvests. But they refused to sell after harvests as they said the new millet tastes much better than their traditional millet, called teff,” Liu told Xinhua.

And that, dear reader, is why we have Latin names.
