Those boundaries are now on course to be crossed across major growing regions, with profound implications for global food security. Diversity to the rescue?
- An inter-specific Amaranthus pangenome captures genetic variation potentially underlying key leafy vegetable traits in this underutilised crop. A rich reservoir of previously hidden diversity emerges from across multiple cultivated amaranths, offering breeders new options for improving a neglected but nutritious vegetable.

Brainfood: Markets edition
- “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.

When the levee breaks
A piece in The Tribune, an English-language daily out of Punjab, reminded me that we have discussed crop diversity and flooding quite a bit here over the years. The article, entitled “Community seed banks help flood-hit Punjab farmers restore crop productivity,” discusses how an initiative of Punjab Agricultural University supported farmers to establish community-level repositories of crop diversity that are turning out to be useful in recovering from recent flood.
Sharing his experience, Paramjeet Singh, a farmer from Baopur Jadid, said that timely access to quality seeds through the community seed bank enabled him to sow his crop without delay and achieve a yield of around 23 quintals per acre.
Farmers acknowledged that the initiative has significantly reduced reliance on outside seed sources, minimised sowing delays, and improved overall crop outcomes. They are also retaining seed of the new wheat variety PBW 872 for the next season. The initiative has strengthened local seed exchange systems and enhanced community preparedness against climate-related challenges. By ensuring the availability of quality seeds within villages, the Community Seed Bank initiative is contributing to sustainable agricultural development and improving the livelihood security of farmers in flood-affected areas.
A couple of points about this are worth noting.
First, only improved varieties are mentioned in the article, but normally community seed banks will also conserve local landraces. I don’t know if this is the case in Punjab, but I do hope so. As Jeremy put it here all of 15 years ago, in a post on a study of rebuilding cowpea cultivation after flooding in Mozambique, that and similar experiences support “the more general conclusion that seeds already in the local system offer the best chance of restoration.” Although do read the comments to that post. It seems that in another case some farmers weren’t particularly interested in recovering the exact varieties they had lost.
Which brings me to the second point. Which is that I also hope that those community seed banks have good links with the national genebank. This can act both as back-up and as a source of new diversity, as I suggested myself in a more recent post after floods in Pakistan.
