- Plant diversity modifies multi-trophic interactions in croplands, grasslands and forests. Increasing plant diversity changes the interactions between plants, herbivores and their natural enemies, but exactly how depends on the ecosystem. Diversification’s pest-suppression magic looks like a farming-specific trick, not a universal law.
- High-resolution carbon and biodiversity mapping shows correlated losses across space and agricultural products. Carbon loss and biodiversity loss from farming turn out to hit the same ground: two-thirds of both concentrated on one-third of agricultural land, with beef and milk alone responsible for 41% of the biodiversity damage. Good news for anyone hoping one policy lever could do double duty.
- Harnessing agri-food system microbiomes for sustainability and human health. Soil to gut, it’s all one network, linking ecosystem function, food production and human health across the entire agri-food system.
- Breeding for beneficial microbial associations. If microbiomes matter that much, why not breed for them? A proposed framework pairs crop traits that recruit good microbes (root exudates, architecture) with soil practices that keep those microbes around, since good genetics on ruined soil gets you nowhere. This means designing crops as participants in ecological networks rather than as isolated organisms.
- Host genetics and social relationships jointly shape fitness-associated microbiome variation in a population of feral horses. Nature’s own microbiome-breeding program: seven years of horse poop from Sable Island shows gut microbes predict winter survival, and related horses share microbes more than chance allows. So the functional unit of adaptation is the animal plus its microbiome.
Nibbles: Amaranth webinar, FARA on fonio, Maslin, Gaza genebank, Nepal seeds, Golden Triangle tea
- New webinar series from the American Society of Plant Biologists will explore how underutilized (or is it opportunity) crops like amaranth can contribute to nutrition, food security and rural livelihoods.
- FARA highlights the tiny West African grain fonio as another crop with potential to improve nutrition, strengthen food systems and create new opportunities for farmers and value chains.
- Taiwanese tea has travelled an unlikely route into northern Thailand. It too was an opportunity crop at one time.
- Ethiopian farmers may have been practising regenerative agriculture for millennia, mixing wheat, barley and other grains in the same field. The Rockefeller Foundation is on it.
- Efforts to restore the Al Qarara Seed Bank in Gaza are offering a small but significant form of agricultural recovery.
- In Nepal, indigenous seeds are losing ground to hybrids, but seed advocates are fighting back.
Brainfood: Avocado history, Brazil commuity seedbanks, Citizen science, Agroecology double, Indigenous knowledge, Turkish seeds, Swiss biodiversity
- 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.
