Three different ways of looking at Africa

I ran the Last of the Wild dataset I talked about yesterday past our friend Andy Nelson, he of the accessibility map, and his reaction was that there was a quick paper, or at least an MSc thesis, in comparing that map with his and with the product of the GLOBIO project. Well, here’s what Africa looks like according to the three different methodologies, just to give you a taste. Quite similar, at first look, though we’ll have to wait for that MSc to be sure, I guess. Now, the question is, can such data be used to predict things like the amount of agrobiodiversity in farmers’ fields?

The call of the wild

Not sure how long they’ve been available, but I’ve just learned that the new versions of the Last of the Wild maps are out. The first version is a few years old now.

The Wildlife Conservation Society (WCS) and the Center for International Earth Science Information Network (CIESIN) at Columbia University have joined together to systematically map and measure the human influence on the Earth’s land surface today. The Last of The Wild, Version Two depicts human influence on terrestrial ecosystems using data sets compiled on or around 2000.

These are Europe’s most untouched areas:

Not much left. There are also global and continental maps of human footprint and human influence index, although I must say I haven’t fully digested the difference between the two. And you can download the data and play around with it yourself, of course. Let the mashing begin!

Visualizing agrobiodiversity in markets

I’ve just come across two Flickr groups which are intensely interesting from an agrobiodiversity perspective. Flickr is a photo sharing site, and I have in fact blogged about it before here, for example on how it could be used to map crop diversity. The two groups bring together photos taken in markets, with a lot of fruits and vegetables featured. As with my previous post on tomatoes, have a look at the mapping option in particular. A great time-waster, but I bet it could be used to look at geographic patterns in vegetable diversity in markets.

Agricultural biodiversity weblogger awarded prize

Our friend, colleague and occasional contributor Andy Jarvis has just won GBIF’s prestigious Ebbe Nielsen Prize for 2009 for “combining biosystematics and biodiversity informatics research in an exciting and novel way”. A lot of his work has been on the spatial analysis of the geographic distributions of crop wild relatives, with a view to developing strategies and priorities for their conservation, in particular in the context of climate change. A lot, but far from all: Andy is nothing if not versatile, and his interests extend to the whole of agrobiodiversity. A recent interview with Andy, and others, tries to answer the question “why maps?”. Congratulations to Andy!
