- Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns. DNA from landraces, and interviews with farmers, show that people transported and cultivated avocados across the Americas long before European contact, with landraces from lowland Nicaragua and Honduras in particular showing evidence of ancient migration from South America.
- The Circle of Seeds: An Ethnography of Seed Guardianship and the Making of Agroecological Futures in Paraná, Brazil. Community seed banks depend on relationships of care, reciprocity and collective labour, especially among women farmers, and not just on knowing how to store seeds properly. Though that helps, clearly.
- iNaturalist as a Tool to Improve Agroecological Biodiversity Knowledge: An Ecuadorian Case Study. A citizen science platform can strengthen agroecological biodiversity knowledge, but more efforts are needed to engage farmers.
- Are agroecological practices pro-poor? Evidence from smallholder farms in Zimbabwe. Farmers using agroecological practices were generally wealthier and their farms were more diverse in crop and livestock species, but the association between the use of improved practices and diet outcomes was inconsistent.
- Regenerative agriculture for dietary diversity and food security in Zambia. Agroecological practices were positively correlated with improved dietary quality and food security, including (though not exclusively) through farm production diversity. No word on the wealth of the farmers involved.
- Indigenous Peoples’ knowledge systems and practices for climate survival. Indigenous knowledge systems, including of farmers, offer tested approaches to climate adaptation and resilience that warrant a central place in responses to environmental change.
- Guardians of Agricultural Biodiversity: Farmer Perceptions and Sustainability of Local Seed Varieties in Turkish Highlands. Farmers continue to maintain local seed varieties, driven as much by social, cultural and market considerations as by agronomic performance. But they need support.
- Religion, spirituality and faith of Swiss farmers in relation to biodiversity-linked farming behaviour. Farmers’ religious and spiritual values can shape biodiversity-friendly management decisions, showing personal belief systems are important in conservation. Even in Switzerland.
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?
