- Grinding, fermenting, and detoxifying our way to bigger brains — an anthropologist makes the case that food processing, historically women’s work, did as much for human evolution as the mammoth-spearing got credit for.
- Speaking of transforming raw ingredients into something civilization-defining: a Japanese temple has been quietly perfecting vegan cooking for 700 years, no marketing department required.
- Meanwhile in the Philippines, Naturland, the international association for organic farming from Germany, is linking up with Global Seed Savers Philippines, to help farmers get their hands on indigenous crop diversity before it disappears.
- If you want to see what “future-proofing seeds” looks like at scale, the National Soybean Germplasm Collection just turned 100: a century of squirreling away soybean diversity, just in case.
- Kazakhstan wants in on the squirreling too: plans are moving forward for a new genebank to safeguard agricultural biodiversity across Islamic Organization for Food Security member states.
- The University of Reading is also 100, and in celebration scientists there harvested beans from its cacao collection (yes, it has a cacao collection) to make Britain’s first homegrown chocolate bar since 1932, a novelty act with a serious undertone: climate change is squeezing cacao’s traditional growing belt.
- And in Italy, the squeeze is already showing up on the balance sheet: Parmesan’s “Fort Knox” — $350 million of cheese squirreled away as loan collateral — is feeling the heat, with rising cooling costs and falling yields rattling wine and olive oil too.
Nibbles: Festivals, Wheat breeding, Cowpea, Community seed bank, Mint diversity
- Festivals, rituals and seed-saving go hand in hand, as this photo essay on Koraput’s Adivasis shows for World Indigenous Peoples Day.
- Speaking of unlikely alliances, Israeli and Palestinian researchers have teamed up on wheat that can take the heat in a warming, drying Middle East.
- Not to be outdone in the resilience stakes, the cowpea shrugs off both drought and flooding, according to FAO.
- If all this talk of resilient crops has you inspired, here’s a how-to on starting your own community seed bank, in South Africa or anywhere else for that matter.
- And for when preservation is really about nostalgia: Romania’s Buzau genebank is keeping childhood mint flavours alive, chocolate, clove and vanilla notes included.
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.

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.
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?
