- Global spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation. For 8 of 10 major crops, yield gaps have widened steadily from 1975 to 2010 over most areas, and remained static for sugar cane and oil palm. Time to turbo-charge the breeding?
- Domestication and the evolution of crops: variable syndromes, complex genetic architectures, and ecological entanglements. If you want to turbo-charge breeding, you need to understand (among other things) the ecological context of domestication.
- Including Traditional Ecological Knowledge (TEK) in Agricultural Research: Guidelines and Lessons Learned. I suspect Traditional Ecological Knowledge can help with figuring out the ecological context of domestication.
- High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement. Ok, but ecological knowledge would like a word.
- Understanding genetic diversity in drought-adaptive hybrid parental lines in pearl millet. Any link to ecology of original collecting sites, I wonder?
- Genetic Diversity and Population Structure Analysis of a Diverse Panel of Pea (Pisum sativum). Again, ecological knowledge conspicuous by its absence. Maybe the passport data just weren’t up to it?
- Banana seed exchange networks in Burundi – Linking formal and informal systems. Yes, yes, it’s not just about the breeding, the seed system also has to work.

Forgotten crops in the limelight
The paper “Forgotten food crops in sub-Saharan Africa for healthy diets in a changing climate” by Maarten van Zonneveld, Roeland Kindt, Stepha McMullin, Enoch G. Achigan-Dako, Sognigbé N’Danikou, Wei-hsun Hsieh, Yann-rong Lin, and Ian K. Dawson has won the PNAS 2023 Cozzarelli Prize for the best paper of the year in Applied Biological, Agricultural, and Environmental Sciences. Here’s the abstract:
As the climate changes, major staple crop production in sub-Saharan Africa becomes increasingly vulnerable. Underutilized traditional food plants offer opportunities for diversifying cropping systems. In this study, the authors used climate niche modeling to assess the potential of 138 traditional food plants to diversify or replace staple crop production in sub-Saharan Africa by 2070. The authors report that staple crops may no longer be able to grow at approximately 10% of locations by 2070. Further, the authors identified 58 traditional crops that provide complementary micronutrient contents suitable for integration into staple cropping systems under current and projected climatic conditions. The results suggest that diversifying sub-Saharan African food production with underutilized crops could improve climate resilience and dietary health.
And here’s a video explaining the results:

- Nice video celebrating seeds.
- Nice old video about Kew Gardens.
- Tracing the origins of Indonesian cassava. No, it wasn’t introduced by Kew, but yes, colonialism was involved.
- Latest data on where crops are grown. Including cassava.
- Self Help Africa director turns on to neglected crops. Including cassava.
- New lab in Kenya for spreading clean crops around. Including cassava?
- Türkiye’s genebank in the news. No cassava.
- Nepalese rice gets a Welsh upgrade.
- Collecting sugarcane in French Polynesia to (eventually) support local booze industry.
- Long live the ancient booze bandwagon.
- Garlic 101.

- Food matters: Dietary shifts increase the feasibility of 1.5°C pathways in line with the Paris Agreement. Go flexitarian.
- Biodiversity footprints of 151 popular dishes from around the world. Go flexitarian?
- Periodic Table of Food Initiative for generating biomolecular knowledge of edible biodiversity. Unclear if flexitarians have the best molecules.
- Environmentally protective diets may come with trade-offs for micronutrient adequacy. More sustainable may mean less nutritious. Flexitarians unavailable for comment.
- Market engagement, crop diversity, dietary diversity, and food security: evidence from small-scale agricultural households in Uganda. Market access and crop diversification are both good for dietary diversity and food security. The ultimate flexitarianism.
- Sustainability of one-time seed distributions: a long-term follow-up of vegetable seed kits in Tanzania. Now watch flexitarians demand an even playing field.
- Developing holistic assessments of food and agricultural systems: A meta‑framework for metrics users. One framework to rule all of the above.

- More on the US push for opportunity crops.
- Oh look there’s a whole compendium on African opportunity crops from FAO.
- Many of them are roots and tubers.
- For the Hopi, maize is an opportunity crop.
- For the Adivasis, it’s rice.
- And more along the same lines from Odisha.
- Llamas were an opportunity for lots of people down the ages.
- …and still are, for some.
- Portugal eschews llamas for an ancient cattle breed.
- I bet Mexico’s genebank offers some amazing opportunities.
- And New Zealand’s too.
- Let’s not forget bats. Yes, bats.
- Jeremy’s latest newsletter tackles turmeric, pepper and sweet potatoes, among other things.
- And the best way to frame all of the above is that the World Economic Forum wants governments to ban people from growing their own food because that causes climate change.
