- An insular in situ Coffea arabica resource from Rapa Nui (Easter Island): SSR uniformity and biochemical evaluation of material consistent with the Typica lineage. Coffee growing on remote Rapa Nui appears to represent a remarkably uniform population closely related to the historic Typica lineage. Not diverse doesn’t necessarily mean not interesting.

- Novel food ingredients from Cyperus rotundus: an ancient famine food and the world’s most pernicious weed comes back to the table. One of the world’s most notorious weeds may also be an overlooked food crop, and a potential source of novel food ingredients. An opportunity weed?
- Market remoteness and the production–diet association in smallholder food systems: Evidence from rural Nepal. Growing a diverse range of crops does not always translate into a more diverse diet. In Nepal, the relationship depends strongly on market access, highlighting the importance of infrastructure alongside agricultural diversification. Ok, forget the nut grass then, at least far from markets.
- Pollinators support the nutrition and income of vulnerable communities. Pollinator diversity makes important contributions to both dietary quality and household incomes among vulnerable communities.
- Seed ageing increases the influence of native microorganisms on germination. As seeds deteriorate, their naturally associated microorganisms play an increasingly important role in determining whether they successfully germinate. Of course microorganism diversity had to get a look-in too.
Nibbles: Kenyan crops, Omani mangoes, Wheat mixtures, Wagyu origins
- Kenyan farmers are rediscovering indigenous crops.
- Oman discovers it has lots of mango diversity, and moves to conserve it.
- Swedish student discovering varietal mixtures.
- Discover how a locally adapted cattle population in Japan became a globally recognized premium brand by maintaining distinctive genetic and breeding characteristics. Lessons there for all of the above perhaps?

Fisheries in Samoa depend on significant but largely unrecognized labour by LGBTQ+ people, particularly fa’afafine and fa’afatama, whose contributions are overlooked by policies based on rigid gender categories.

Rock doves lived alongside people in a major Late Bronze Age port city, revealing a more complex relationship than simple domestication in which doves exploited urban environments while providing food and other resources.

Genome editing was used to produce grass carp lacking the numerous fine intermuscular bones that reduce consumer appeal, opening new possibilities for breeding more marketable fish while deepening understanding of skeletal biology.

Ube careful what you wish for
You know a crop has arrived when The Economist does a piece on it. Ube (Dioscorea alata), the purple yam long cherished in the Philippines, is indeed suddenly everywhere, and the newspaper for the global elite is all over it. From Starbucks drinks in Britain to specialty bakeries in Europe and North America, it has become the latest social-media-friendly food trend. Some commentators are already calling it “the new matcha.” Global demand is rising rapidly, and Filipino farmers are struggling to keep up.
This looks like the kind of success story we often hope for as agricultural biodiversity advocates: a neglected or underutilized crop finally finding big markets. Researchers are developing improved varieties, governments are increasing investment in research and development, and scientists are working on better propagation methods to overcome shortages of planting material. Some farmer groups have reportedly seen orders jump from hundreds of kilograms to tens of tonnes. What’s not to like?
Well, before we celebrate too loudly, it is worth remembering that similar “opportunity crops” have started on this road before. It can be a bumpy one.
The first challenge is biological. Ube is not an industrial commodity. It is seasonal, labor-intensive, relatively slow to mature, and constrained by shortages of high-quality planting material. Current efforts to develop improved varieties and rapid propagation techniques are responses to real bottlenecks, not merely opportunities.
The second problem is economic. Today’s enthusiasm is driven partly by novelty and social media visibility. Food history is littered with once-fashionable ingredients that enjoyed a brief boom before consumers moved on to the next trend. If ube is indeed the new matcha, what happens when the next matcha arrives?
Finally, there are legitimate concerns about diversity itself. Commercial success often narrows the genetic base of a crop as supply chains converge on a small number of elite varieties. Ironically, a boom can threaten the very diversity that made a crop valuable in the first place.
None of this means we should resist ube’s moment. On the contrary, it presents a rare opportunity to reward farmers, strengthen local value chains, and invest in conservation and breeding. But history suggests that the goal should not be to maximize production for a transient craze. It should be to use today’s demand to build a resilient and diverse ube sector that can survive after the craze fades.
Don’t just feed the boom. Try to avoid the bust. More tomato, less quinoa, you could say.
