No one expects the Spanish Inquisition to help opportunity crops

The latest episode of Eat This Podcast explores why the tomato, first recorded in England in the 1590s, took more than a century to become an important food. The explanation offered was that it took a combination of factors: a somewhat warmer climate, the movement of people and culinary traditions caused by the Spanish Inquisition, and its connection with another New World crop, the chile pepper. Do listen to the episode, it’s a fascinating story.

What struck me most about it was how little of the tomato’s eventual success depended on technology. Sure, glasshouses and fermenting horse dung helped, but so did luck and recipes.

Today, discussions about agricultural diversification often emphasize research, breeding, seed systems and value chains. The recent paper on the Vision for Adapted Crops and Soils (VACS), for example, lays out an ambitious roadmap to transform Africa’s Cinderella “opportunity crops” through investment in breeding, seed delivery, agronomy, markets and policy support.

There is much to admire in that vision. Many neglected crops undoubtedly suffer from decades of underinvestment. Better varieties, better seed systems and better market access could surely make a substantial difference.

Yet the tomato’s history offers an interesting counterpoint.

The tomato did not become a success in England back in the early 1700s because somebody developed an improved variety. It did not require a major breeding programme. It was not the product of a coordinated development initiative. Rather, its rise seems to have depended largely on changes in climate, cuisine and culture. People learned how to use it. They incorporated it into recipes. It found a place within evolving food traditions.

In other words, the tomato became important because food systems adapted to it, not because the crop itself was somehow transformed.

This is not an argument against VACS. Rather, it is a reminder that technological interventions are only part of the reason why crops become successful. History suggests something else is needed too.

The tomato spread because it became embedded in dishes that people wanted to eat. The chile pepper may have played a role in that process, helping to create new flavour combinations and culinary traditions in which tomatoes made sense.

For some of Africa’s opportunity crops, the principal constraint may well be genetic improvement. For others, however, the limiting factor may lie elsewhere. Middle-class consumers may not know how to prepare them. Urban markets may not value them. Food processors may not see commercial opportunities in them. In such cases, the most effective intervention may not be a breeding programme but a chef, an entrepreneur, a recipe book or a social media campaign.

The VACS paper rightly argues that there should be “no romance” about opportunity crops. But perhaps there should also be no assumption that technological tweaking is always the decisive factor.

The history of the tomato suggests that crops can sometimes become important without being substantially “improved” at all. What matters is whether societies discover compelling reasons to grow, sell, cook and eat them.

That is a useful reminder that agricultural diversification is ultimately as much a cultural process as a technological one. Though we could probably do without the Spanish Inquisition.

Brassica on the brink

How did collards get to remote oases on the edge of the Sahara? That’s what ethnobotanists Bronwen Powell and Abderrahim Ouarghidi have been looking into for like 20 years now, and it’s a fascinating story. Which you can read about in detail in their paper in Economic Botany. They also present an abbreviated form of the argument in The Conversation. Which got Nibbled some months back, though without giving anything away. But actually what I recommend you do is listen to Jeremy interview the intrepid duo in the latest episode of Eat This Podcast.

Happy birthday MSB!!!

It’s the 25th birthday of Kew’s Millennium Seed Bank (MSB) at Wakehurst in West Sussex.

Understandably, it’s getting a lot of — very well-deserved — coverage. I’ll link to some of the more interesting pieces as they come out over the next few days.

  • There’s a podcast hosted by King Charles, no less.
  • The Guardian’s podcast is shorter and less cool but ok.
  • Cate Blanchett is appearing in that royal podcast, as well as various more plebeian interviews. She’s the MSB’s first ever ambassador. She was recently featured, along with Wakehurst, in House & Garden.
  • The Economist has a long piece about seed collecting for the MSB in Madagascar.
  • RE:TV has produced a cool video.
  • The BBC’s video is shorter and less cool but ok.
  • Samara, the International Newsletter of the Millennium Seed Band Partnership, has a very comprehensive anniversary edition.

Here’s to the next 25!

Nibbles: Millennium Seed Bank 25th, NPGS, Maize germplasm, Breadfruit genebank, Banana genebank

  1. King Charles III talks about seeds with Dr Elinor Breman of Kew’s Millennium Seed Bank and…
  2. Cate Blanchett.
  3. Or read about it in The Economist.
  4. Or watch a nice video.
  5. The seed banks of the National Plant Germplasm System in the USA are for farmers, not just researchers.
  6. How to get stuff out of the NPGS.
  7. Laurajean Lewis: from an NPGS genebank to CIMMYT’s.
  8. I’m sure she and Chris Mujjabi will get to know each other soon.
  9. Diane Ragone: Not all genebanks are seed banks.
  10. Not a lot of breadfruits in Belgium but, surprisingly, lots of bananas.

Nibbles: China grasslands, Edible lily, Ag data, China potatoes, CIP genebank, Vavilov book, Ghana seeds, Nutrition enterprises, Seed production films, Khoury pod, Relais & Châteaux

  1. China rehabilitates its grasslands.
  2. Not content with that, China breeds a new edible lily.
  3. Not sure what food group lilies are in, but farmers are growing more fruits and vegetables, it seems.
  4. Still not resting on its lilies, China breeds climate-smart potatoes.
  5. No doubt CIP and its genebank is helping with that.
  6. There’s a new book on Vavilov and his genebank. He knew a thing or two about potatoes.
  7. Ghana is totally on board with the whole genebank thing. And the Dutch are helping.
  8. Genebanks should hook up with small- and medium-sized enterprises for nutrition. What, not large ones?
  9. Genebanks also need nice education films on seed production.
  10. Friend-of-the-blog Colin Khoury interviewed on In Defence of Plants podcast.
  11. Luxury hotels and restaurants hook up with UNESCO to protect biodiversity. Vavilov would have been so proud.
