As a young biology student, one of the things I and my classmates worried about was population. You didn’t need to be a mathematical whizz to understand the force of Thomas Malthus’ argument in An Essay on the Principle of Population, even if you didn’t agree with the methods he proposed for dealing with it. Firebrands like Paul Ehrlich whipped us up, and Limits to Growth from the Club of Rome provided food for thought as we contemplated future famines. And then, just like that, population vanished as a suitable subject for conversation.

A textual analysis of loads of published works on how to feed the world confirms this impression. The number dealing with population becomes vanishingly small, even while those about increasing production just keep going up. A conversation with one of the paper’s authors, Giangiacomo Bravo of Linnaeus University in Sweden, prompted me to look back at some of the history.

Notes

  1. The trigger paper for this episode was From population to production: 50 years of scientific literature on how to feed the world. It is, alas, behind a paywall.
  2. The Population Bomb is online, as is a 2009 appraisal of their work by Paul and Anne Ehrlich
  3. I’m grateful to The Internet Archive for all the work they do. That’s where I found archive tape of Paul Ehrlich, Newsweek and Joseph van Arendonk. Jørgen Randers was from YouTube.

Modern livestock breeds are incredibly efficient, gaining weight at a prodigious rate and supplying astonishing quantities of milk and eggs. That efficiency, however, comes at a cost: the food needed to support such a metabolism. Much of that food could be eaten directly by people, and certainly the lush pastures that support modern dairy cows, for example, might be put to better use growing food for people. But then, where will our meat, milk and eggs come from?

Lawrence Alderson founded the Rare Breeds Survival Trust in the UK in 1973. Those breeds, he contends, are the key to future food security. It is thanks to the foresight of Alderson and other visionaries around the world that rare and heritage breeds are still here to convert stuff we can’t eat into stuff we can eat.

Notes

  1. Lawrence Alderson’s has a website. His new book is The quest to conserve rare breeds: setting the record straight. If you follow that link (which is an affiliate link), you’ll do better by clicking on the flag at top right and switching to the UK front for bookshop.org.
  2. Here’s where to find out more about the Rare Breeds Survival Trust.
  3. I remain dubious about the whole Sir Loin story, although I wasn’t going to press the point any harder than I did. Wikipedia seems to agree: “There is no reliable evidence for this explanation and scholars generally hold it to be a myth.” I don’t doubt that James I of England dined on some fine beef at Hoghton Tower in 1617, and the beef could well have come from White Park cattle. Did he knight it? Convince me.
  4. In case you were wondering about the new herds of Northern Shorthorn Dairy cattle, I think this is one of the places Lawrence Alderson was talking about: Stonebeck Raw Wensleydale Cheese.
  5. Rules 4 and 10 of Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits are why you should not plant trees on uplands.
  6. Here is the transcript.

Another year, another International Year. Several, probably. The one that concerns me is the International Year of Fruits and Vegetables, as designated by the United Nations and implemented by the Food and Agriculture Organization of the United Nations.

I’m deeply skeptical about these things, and always wonder how else the money could have been spent to better effect. But the money is never available to be spent on anything else. So I’ll just take the opportunity to rail against people who can’t seem to separate the partially overlapping magisteria of botany and cuisine.

Notes

  1. International Year of Fruits and Vegetables 2021
  2. I just need to tidy up my notes, and then there’ll be a transcript here.
  3. New year, new season, new appeal for support.

Portrait of Professor Donald Worster
Professor Donald Worster
It’s time to face an uncomfortable fact. After more than 200 episodes devoted in their various ways to what we eat and drink, I’ve never looked at the direct consequences of all that ingestion: excretion. Time to remedy that, by talking to Professor Donald Worster. The ostensible reason is his essay The Good Muck: Toward an Excremental History of China. While we do discuss the origins and details of what he calls “the faeces economy,” there’s a lot more to it than that. Excrement is unavoidable. But is it simply a waste product, to be dumped out of sight and out of mind? Or is it a valuable resource that we squander at our peril?

Notes

  1. I’m pretty sure that neither of the Donald Worsters you will locate on Twitter is the real thing. However, The Good Muck: Toward an Excremental History of China is available to download at The Rachel Carson Center.
  2. Here’s the transcript.
  3. The problem of human waste is still with us, even in the “rich” world. Two weeks ago, The New Yorker published The Heavy Toll of the Black Belt’s Wastewater Crisis.
  4. The poor world too, more so, but for some reason the people actually doing something about it don’t want to talk to us about their work.
  5. You can also download Franklin King’s Farmers of Forty Centuries; or, Permanent Agriculture in China, Korea and Japan, which is where I got the banner photograph.

How the Brits became a nation of tea drinkers Coffee leaf rust in Ceylon had very little to do with it

Erika Rappaport
Erika Rappaport’s study of tea meticulously documents the many ways in which tea, as it became one of the first global commodities, was responsible for so many aspects of modern life. In the course of our conversation, it became obvious that there is no single reason why the Brits turned to tea. They were drinking roughly equal amounts of tea and coffee to begin with, long before coffee leaf rust arrived in Ceylon, but it was mostly Chinese tea. When the British East India Company decided to try their hand growing tea in Assam, they came up against one big problem: back home, nobody much liked the taste of Indian tea. Persuading them to change their minds was a massive undertaking involving racist rhetoric, fearmongering, and little glimpses of heaven on earth. And it worked.

“Comparative Consumption,”
Sir James Buckingham, A Few Facts about Indian Tea and How to Brew It
(London: Indian Tea Association, 1910, p. 4. British Library shelf mark 07076.48 (4).

Notes

  1. Erika Rappaport shared just a few stories from tea’s not so glorious history. There is masses more in her book, and if you’re looking for a long read in which to lose yourself (or a loved one), I highly recommend A Thirst for Empire: How Tea Shaped the Modern World.
  2. Not entirely by chance, I also watched a video of William Dalrymple talking about his newish book The Anarchy: The East India Company, Corporate Violence, and the Pillage of an Empire. Tea barely gets a look in, but there is so much else to digest.
  3. There is now a transcript, thanks to the show’s supporters
