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.

Brainfood: Collaboration edition

Dietary diversity, food security, and development projects in low- and middle-income contexts: Findings from 24 countries. Development projects are most effective at improving dietary diversity and food security when they bring together agriculture, nutrition and local communities.
Enhancing farmers’ access to neglected crop seeds for healthy diets in a changing climate: six recommendations for policy action. Improving farmers’ access to opportunity crop seeds requires coordinated action across seed systems, with researchers, policymakers, seed producers and farming communities all playing complementary roles.
The effects of seed policies, laws and regulations on farmers’ ability to access and use diverse, locally adapted farmers’ varieties and landraces. Seed policies shape collaboration between farmers, communities and formal seed systems, and regulations can either enable or constrain the exchange of locally adapted varieties that keeps agricultural diversity alive.
Studying vanishing dietary diversity before it is lost: the World Diet Initiative. The World Diet Initiative brings together nutrition science, ecology and cultural knowledge to understand disappearing food traditions, showing that protecting dietary diversity requires collaboration across disciplines and communities.
The Spanish Network of Genetic Conservation Units: a cooperative tool for the conservation and sustainable use of forest genetic resources under a changing environment. The Spanish Network of Genetic Conservation Units show how sharing expertise and responsibilities can strengthen forest conservation.
Strengthening national genebanks through genomics and regional collaboration: Lessons from Latin America and the Caribbean. A regional community of practice is helping national genebanks overcome technical and institutional barriers through shared genomic approaches, turning isolated collections into connected systems for conserving and using crop diversity.

Nibbles: Apple-banana paradox, Genebanks, Indian wheat, Indian wild rice, Kenya community seed banks, Wild coffee, Macadamia history, Taro research, Cacti

Why the modern food system prizes uniformity even though resilience depends on diversity. Spoiler alert: follow the money.
Historic crop varieties are finding renewed relevance as farmers contend with more volatile weather, emerging pests and changing markets. Let’s hope there’s money to conserve them.
India’s traditional wheat varieties contain diversity that could help breeders develop crops better able to withstand heat and drought. Let’s hope there’s money to conserve them.
India announces significant progress in conserving its wild rice genetic resources. Great that there was money to conserve them.
Community seed banks across Kenya are calling for formal recognition and sustained support, arguing that locally managed collections strengthen seed sovereignty, preserve traditional varieties and help farming communities adapt to climate change. Yes, but are they enough without national genebanks?
Researchers are racing to conserve wild coffee species whose genetic diversity may provide the resistance and resilience needed to secure tomorrow’s morning cup. Is the industry contributing, though ?
New history of the macadamia traces its remarkable journey from Australia’s native forests to a global crop, while underscoring why conserving the remaining wild populations is essential for the crop’s long-term future.
Researchers at the University of the South Pacific investigate how taro can withstand climate change, combining research with conservation to help protect one of the region’s most culturally and nutritionally important staple crops.
Chester Zoo collects seeds from highly threatened cacti, because why not?

Brainfood: Wild chickpea, Feral brassica, Peruvian cacao, Panamanian cacao, Tree diversity, Healthy diets in PNG

Genome-wide molecular diversity analyses identify wild Cicer as reservoirs of variations for chickpea improvement. Wild relatives of chickpea harbour a wealth of genetic variation that has yet to be exploited by breeders. But it’s mainly within species.
Genetic and Morphological Diversity in Spontaneous Populations of Brassica rapa: How Do Feral Populations Differ From Wild Ones? When a crop escapes cultivation, does it become wild again? Apparently not. Pity.
Genetic structure of traditional cacao reveals four new genetic lineages in indigenous Amazonian sites in Peru. Genetic analysis of traditional cacao maintained by Indigenous communities in the Peruvian Amazon uncovers four previously undescribed genetic lineages.
Contrasting germplasm composition and propagation practices in the two major cacao-growing areas in Panama. Two of Panama’s principal cacao-growing regions have developed markedly different genetic profiles, reflecting both the varieties farmers cultivate and how they propagate them. I think they have been previously described though.
Ecological multifunctionality of watersheds increases with tree species richness. Watersheds planted with a greater diversity of tree species perform better across multiple ecological functions simultaneously, including nutrient cycling, soil protection and water regulation.
Nutrition sensitive poverty and its correlates in Papua New Guinea: incorporating healthy diet targets into poverty measurement. Conventional poverty measures ask whether people can afford basic necessities. Why not ask a more demanding question: can they afford a healthy diet? Hopefully meaning a diverse one.
