- “What is the essence of cultivating a crop that does not yield enough to feed my family?” Farmer agency and the management of agrobiodiversity in Ghana and Burkina Faso. Farmers balance subsistence needs and market opportunities when deciding which crop varieties to maintain. Well I never.
- Reassessing the economic returns of diverse traditional agricultural systems for smallholder farmers: a case study of the milpa in Mexico. Diverse traditional farming systems can generate significant economic value; so no, agricultural diversity is not necessarily less profitable than specialization for market production.
- Farmer participatory evaluation of Amaranthus cruentus L. breeding lines for marketable vegetable yield and organoleptic quality under on-farm and on-station conditions. In any case, farmers can work with researchers to select amaranth varieties with traits that improve both marketability and consumer appeal, linking crop improvement directly to market demand.
- Novel soybean type with improved volatile and sensory characteristics of raw soy slurries. Breeding soybean varieties with enhanced sensory qualities can hopefully increase consumer acceptance and create new market opportunities for soy-based foods. Unclear if farmers were involved, but they could have been..
- Can the digital long tail effect in farmers’ markets increase crop diversity on farms and in diets? Yes. Digital platforms can connect niche producers and consumers, creating markets for a wider range of crops, thereby encouraging agricultural and dietary diversity. How about linking seed producers to farmers?
- Preserving crop genetic diversity through traditional seed systems: insights from farmer-saved fonio (Digitaria exilis) landraces in Northern Ghana. Farmer-managed seed systems support the conservation of crop diversity while maintaining access to locally adapted varieties with potential market value. But maybe they could use a digital platform?
- Seeds and social norms: sorghum seed exchange among smallholder farmers in Northern Ethiopia. Cultural practices shape how farmers share seeds, influencing the circulation of crop diversity and farmers’ participation in local seed markets. Good luck with those digital platforms.
Brainfood: Indigenous edition
- Rapid adaptive increase of amylase gene copy number in Indigenous Andeans. Indigenous Andean populations evolved exceptionally high copy numbers of the AMY1 salivary amylase gene, likely linked to long-term adaptation to starch-rich diets associated with potato domestication roughly 10,000 years ago.
- Horse genetics, archaeology, and the beginning of riding. Horse domestication was not a sudden genetic event beginning around 2200–2100 BCE, but a long and regionally varied process in which Indigenous Eurasian pastoralists progressively managed, rode, milked and selectively bred multiple horse lineages over many centuries, transforming mobility and social organization well before the rise of the dominant modern domestic horse lineage.
- Bridging biodiversity and food systems: A nationwide synthesis of non-conventional food plants (PANCs) in Brazil. Brazil’s non-conventional food plants (PANCs) and associated Indigenous and traditional knowledge could help build more diverse, climate-resilient and socially inclusive food systems while strengthening biodiversity conservation, rural livelihoods and public food programs.
- Indigenous Wisdom for a Changing World: Bridging Traditional Ecological Knowledge and Biodiversity Conservation. Sacred groves and other community-managed landscapes in central Ethiopia conserve high levels of biodiversity through Indigenous institutions, ritual practices and traditional ecological knowledge, suggesting that effective conservation depends on treating cultural stewardship systems as integral to ecological resilience rather than as secondary to scientific management.
- When Knowledge Isn’t Free: Legal and Ethical Imperatives of Protecting Indigenous Intellectual Property. There’s a persistent mismatch between Western intellectual-property regimes and Indigenous concepts of collective ownership, biocultural heritage and intergenerational custodianship of knowledge, and that’s unfair.
- Crediting and citing Indigenous Knowledges within research. Biodiversity conservation becomes more effective when Indigenous scientists and communities participate as equal partners rather than merely as local stakeholders or informants.
Humble crop beats superfood
Two articles about the contrasting fortunes of Andean crops came out last week. They describe different sides of the same broad story: Indigenous agricultural systems are highly biodiverse and increasingly positioned as climate adaptation strategies, but they are also under pressure.
In Peru, potato farmers in places like the Parque de la Papa are actively conserving thousands of native potato varieties as a form of insurance. This is climate change adaptation: maintaining agrobiodiversity, preserving traditional knowledge, and using resilient crop varieties and farming practices to buffer against warming temperatures, erratic rainfall, and pest and disease pressure. The message is that crop diversity itself is a survival strategy, both ecological and cultural.
The recent history of quinoa in Bolivia shows the same system under a different kind of stress: global demand drove a commodity boom that incentivized monoculture expansion and mechanization, which in turn contributed to soil degradation, erosion and reduced resilience. Coming back from that is proving difficult.
Together, the two cases show that when Indigenous agroecosystems are treated as living repositories of diversity, they can enhance resilience, including to climate change; and that when they are pulled into boom-driven export specialization, that resilience can be undermined. The shared lesson, at least for me, is that climate adaptation in mountain agriculture depends on maintaining ecological and genetic diversity embedded in Indigenous land management systems.
A point that I suspect is highlighted in the book Andean Potatoes and Quinoa: Origin, Current Status and Recipes of Ancestral Crops, also recently announced.
Nibbles: Pearl millet redux, Garden plants, Armenian pics, Seeds galore, Heavenly Book, Pastoralism threats
- Pearl millet is getting the hybrid treatment. And, loving it.
- Want to know what to grow in your garden? Yes, even pearl millet.
- Nice pics of Armenian landscapes, food and foodways. No pearl millet in sight.
- The latest monthly newsletter from The Botanist in the Kitchen does seeds. Pearl millet unavailable for comment.
- China is genotyping and phenotyping (almost) everything. Pearl millet feeling left out.
- If pearl millet fails, there is always pastoralism. No, wait…
Gaps galore in collards collections
Quick follow-up to my post a few days ago on the recent study of the origin of the collard greens grown in the Moroccan oases of the Draa and Ziz valleys.
Ethnobotanists Bronwen Powell and Abderrahim Ouarghidi used historical texts, linguistics, and Indigenous knowledge in their investigation, but of course it’s also possible to use genetics to figure out where the plants may have came from. Especially as there are plenty of accessions labelled Brassica oleracea var. acephala in the genebanks that share their data on Genesys — just over 1500 in fact.
Alas, that might in practice turn out to be tricky, though, due to the somewhat — ahem — skewed geographic distribution of the accessions in question. The yellow circles in the map below show the approximate locations of those oases on the edge of the Sahara.
Still worth trying, in my view, but really more than anything this should be an encouragement to do some more collecting. Or get more genebanks on Genesys. Or identify more B. oleracea accessions to variety level. Or…
What else has been collected in the Draa and Ziz valleys or thereabouts? Surprisingly little, mainly wheat, barley, chickpea, faba bean and alfalfa. The general location of the valleys is now shown by white squares.
Incidentally, the. map below is where ChatGPT thinks collards are grown around he world. I really have no idea how accurate it is. I hope someone will tell us.
