I want to put up another quick post on the theme of innovative marketing of so-called “opportunity crops” in Kenyan supermarkets. Yesterday it was nicely packaged frozen amaranth leaves that struck me. Today it’s pre-cooked single portions of traditional dishes. No need to refrigerate. Just heat. And eat.
Frozen amaranth and warm memories
Coming across this new (at least for me) frozen amaranth product in a Nairobi supermarket yesterday…
…reminded me that the Amaranth Institute Symposium 2026 is coming up soon.
It really is amazing the progress in the marketing and consumption of traditional vegetables that Kenyans have made in the 30 years since I made my infinitesimal contribution.
Nibbles: Tigray grapes, Latin American opportunity crops, Hawaii & Cayman coconuts, North Macedonian collecting, South Korea seed vault, Eswatini seed hub, Expensive healthy diets
- A North Macedonian professor’s 15-year rescue mission for landraces and crops surviving only in remote villages. Why bother? Stay tuned…
- Ancient grapevines in Tigray represent a unique genetic lineage with potential value for breeding varieties adapted to dryland conditions.
- Hawai’i Public Radio checks in on Maui’s coconut genebank. Useful to breed varieties adapted to really wet conditions, presumably.
- The Cayman Islands are also hoarding coconuts, along with lots of tasty fruits.
- A USD 400,000 boost from Taiwan for the Eswatini national genebank. Indigenous vegetables get much-needed love.
- A regional survey of 25 orphan crops across 13 Latin American countries finds quinoa and amaranth well-catalogued, but characterization budgets are the real bottleneck. Collecting and conserving in genebanks is great, but not enough.
- South Korea puts 330,000 seed accessions under “double lock”, hedging against both climate change and war. Conserving in one place is not enough.
- FAO warns that nearly a third of the world can’t afford the USD 4.28 a day that a healthy diet costs — nearly three billion people, and rising. That’s why we need al the above, I guess.

We’re moving house so this might be the last post for a while. See you on the other side. In the meantime, enjoy this bunch of papers on different applications of spatial analysis to agricultural biodiversity and associated topics.
- Addressing global hotspots of drought-related crop production losses. A crop-specific drought sensitivity metric for 17 major crops finds rainfed production losses of 10% globally under historically observed extremes, enough to feed 2 billion people, with hotspots in the US Midwest, eastern Brazil, the Mediterranean and South Asia. Sustainable irrigation expansion and crop switching could avoid 60% of those losses. No word on varietal change, but I’m sure it would help.
- GEM-Forest: A Global satellite EMbedding–based map of forests and tree crops for 2020. Using Google DeepMind’s Alpha Earth Foundation embeddings, this 10 m global dataset classifies forest, non-forest and tree crop areas with 90% accuracy, showing that lightweight classifiers on satellite embeddings 1 can rival more complex forest-monitoring pipelines built to support things like the EU Deforestation Regulation.
- Global distribution of cattle, horses, goats, sheep and buffaloes at 1 km resolution for 2000–2022 based on subnational census data and spatiotemporal machine learning. Harmonizing 55,336 census polygons across 147 countries produces annual 1 km livestock headcount and density layers for five species, letting users track shifting grazing pressure over more than two decades rather than relying on single-year snapshots. 2
- A Spatial-Econometric Analysis of Fruit Tree Diversity in Lebanon: A contextual framework for supporting smallholder farmers. How geography, socio-economic conditions and local context shape fruit tree diversity in Lebanon, helping identify where interventions could best support smallholder resilience.
- High-resolution mapping of rice cropping pattern, intensity, calendar, and ecosystem type across Southeast Asia. Joins the growing pile of fine-resolution rice products for the region, this one distinguishing not just how many harvests a field gets but which rice ecosystem (irrigated, rainfed, upland) it belongs to. Is which variety is being grown next on the agenda?
- Entrenchment of cropping patterns reinforces climate exposure for certain crops in US. County-level analysis of US cropping decisions finds that climate risk has actually risen for some crops (like rainfed soybeans) even as it fell for others, suggesting economic and policy incentives are keeping farmers planted in increasingly climate-mismatched patterns rather than nudging them toward the drought-sensitivity-driven switching the first paper above models.
Indigenous people ask for genebanks
Great to see a new Conservation International study, led by Sushma Shrestha (an Indigenous Newar researcher from Nepal), on how Indigenous knowledge protects Earth’s ecosystems. Researchers interviewed 49 Indigenous leaders from six continents about how they steward their land, spanning territory from the Amazon rainforest to East African savannahs and Pacific Islands.
The study pushes back on an all-to-common assumption: that Indigenous lands are ecologically rich simply because they’re isolated or lightly populated. In fact, the health of Indigenous lands, the richness of their biodiversity, and their capacity to store carbon, come directly from active stewardship by the people living there. They’re the product of specific cultural practices, not a mere accident of remoteness.
What cultural practices? Things like avoiding overfishing, maintaining sacred spaces, watching for fires and other threats, and directly resisting extractive industries all contribute to the health of Indigenous territory.
Anything on agricultural biodiversity? Alas, that’s not a framing the paper uses explicitly. However, adaptation strategies that do get mentioned include sowing seeds that can be harvested in a short period to escape flooding, and planting crops in the shadow of trees to cope with rising temperatures. On support needs, there was a specific request for help with the conservation of Indigenous varieties. This is taken up again in the discussion section, which recommends, among other resourcing priorities, the establishment of community seed banks. With the appropriate links to national genebanks, it goes without saying.
