And so they viewed California Indians as lazily gathering the fat of a landscape they had hardly touched.”
Canadian peas in India
Speaking of nifty websites, I’ve just come across resourcetrade.earth, from Chatham House, which enables
…users to explore the fast-evolving dynamics of international trade in natural resources, the sustainability implications of such trade, and the related interdependencies that emerge between importing and exporting countries and regions.
That of course includes agricultural trade, with the data coming mainly from FAO and USDA. Which means you can do interesting mash-ups with the global diets data we blogged about a couple of days back.
For example, here on the left are the data on the contribution of pulses to total food weight in the Indian diet, courtesy of that fabulous CIAT website. Note the steady increase in pea consumption over the past 30 years or so (click on the image to make it bigger, it’s the plot in the bottom right hand corner).
A lot of those peas, it turns out, now come from abroad, Canada mostly (as you can see on the map below). It’s a $500 million market, up from $30 million in 2000.
Now, I don’t know what proportion of Indian pea consumption is down to Canadian imports, but it should be possible to figure it out. I’m betting a fair bit of the aloo mutter you have in Amritsar is made in Canada.
Exploring global diets
You may remember the paper Increasing homogeneity in global food supplies and the implications for food security, which we blogged about a couple of times when it first came out in 2014. National Geographic did a pretty good job of visualizing some of the data online, but CIAT have blown them out of the water now with a fabulous interactive website.
You can listen to Colin Khoury, the brains behind the whole thing, on Jeremy’s latest Eat This Podcast. And you can read about the most surprising results on CIAT’s blog. Spoiler alert:
1. Almost everybody eats a lot more food than their grandparents did. And it’s more diverse.
2. African, Asian, and small island countries have the world’s most diverse food supplies. Also the least.
3. Crop immigrants are the key to dietary diversity.
4. The world’s average diet means eating like people do in Cape Verde, Colombia, and Peru.
5. Political unrest can lead to greater diversity in people’s diets, or less.
There’s also a companion piece by Colin on the Global Plant Council website. And this is what Colin says on his Facebook page:
We built a big data website! When we published our findings of increasing homogeneity in global food supplies, we hadn’t yet found a good way to make the underlying national-level data readily visible to interested readers. This is why I’m tremendously excited to announce the publication of our new Changing Global Diet website, which provides interactive visuals for 152 countries over 50 years of change. We that hope you will enjoy your own investigations of dietary change over time. Perhaps you can tell us where you think the changing global diet is headed.
If you do play around with the website, you can share any interesting stuff you find using the hashtag #changingglobaldiet on Twitter. Me, I’m going to have a bandeja paisa and feel like a proud citizen of nowhere.

- Agrobiodiversity and a sustainable food future. Apparently all you need to do to support the “use of biological diversity in sustainable agricultural and food systems” is to recognize that there are 4 interconnected themes: (1) genetic resources, ecology and evolution; (2) governance policy, institutions and legal agreements; (3) food, nutrition, health and disease; and (4) global change drivers with social ecological interactions.

- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. Occasional seedlings are allowed to survive not so much because they look different, but because they look similar, to existing landraces, even though they may be genetically distinct.
