- Genome-wide comparative diversity uncovers population structure, global distribution, and targets of selection in hexaploid oat. A worldwide survey reveals how oat diversity is structured, spread, and shaped by breeding, helping pinpoint untapped genetic resources for future improvement.
- Genomic diversity and the domestication history of cotton (Gossypium hirsutum). Its genome traces cotton’s journey from its wild origins in Mesoamerica while documenting the genetic narrowing that accompanied domestication.
- Genetic architecture of sugarcane traits in a polyploid genomics framework. New genomic tools finally begin to untangle the diversity of one of agriculture’s most genetically complex crops, exposing the basis of traits breeders have long selected largely in the dark.
- Projected warming will exceed the long-term thermal limits of rice cultivation. Rice has historically thrived within remarkably stable climatic boundaries. 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.
- Impact of gardening and nutrition support provided to women in refugee camps in Cox’s Bazar, Bangladesh. Even in one of the world’s most challenging humanitarian settings, greater interspecific crop diversity translated into better diets, improved food security, and enhanced wellbeing.
- Designing perennial crop-based agroforestry systems: specificities, challenges, and opportunities. Diversification does not stop at the field edge: how perennial crops can be combined with trees to deliver productive, resilient, and biodiversity-friendly farming systems.
- Towards Nature Positive supply chains: From biodiversity commitments to organisational action. What would it take to move biodiversity from corporate promises to business practice? Maybe the above examples can help turn aspiration into measurable action.
Nibbles: Johnny Appleseed, ICRAF genebanks, China lychee genebank, Ethiopian Biodiversity Institute, Saudi tree genebanks, European genebank data, Pricing nature
- Johnny Appleseed basically set up fruit tree genebanks 200 years ago.
- Modern fruit tree genebanks could probably learn something from Mr Appleseed.
- Is there a Mr Lycheeseed, I wonder?
- There are probably some fruit tree collections at the Ethiopian Biodiversity Institute.
- Saudi Arabia is betting on tree genebanks. Maybe even fruit tree genebanks.
- All genebanks need to share their data, according to the guy in charge of helping European genebanks share their data.
- Can you put a value on genebanks? Should you?
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.
Nibbles: Fit for Biodiversity, Food value chains, FAO, SeedTracker, Morocco genetic erosion, Pastoralists, Cannabis seedbanks
- A conference on biodiversity in agri-food systems. Including agrobiodiversity?
- A photo essay about food value chains in India. Including agrobiodiversity?
- A few examples of FAO’s work on how agriculture sustains biodiversity. Including agrobiodiversity.
- An app to track seeds. And therefore agrobiodiversity.
- A warning that 75% of the agrobiodiversity of Morocco’s wheat and barley has been lost in the past 50 years. Ah, so that 75% number is true of something after all. Maybe they could use SeedTracker.
- A reminder that pastoralists guard biodiversity. Including agrobiodiversity.
- A Genesys for weed. Well, I guess it’s agrobiodiversity.
21 things to know about seed systems
FAO has a 6-page leaflet out on “Seed systems – Twenty things you need to know.” It’s well-written and comprehensive. These are the 20 things, in case you were wondering:
- What is a seed?
- What makes some seeds better than others?
- What is seed quality assurance?
- What does it mean when seeds are “certified”?
- What are “quality declared seeds”?
- What work does FAO do on seeds?
- What do seed policies aim to do?
- What is seed security, and why is it important?
- What does FAO do to help farmers after a disaster?
- Why not just give food instead of seeds?
- How do seeds help farmers recover after disasters?
- Where does FAO get the seeds it gives to farmers?
- How does FAO decide what kind of seed help to provide?
- How do emergency seed responses help farmers become more resilient to future disasters?
- What’s the difference between hybrid crop varieties and other types of varieties?
- Are older, farmers’ varieties better than newer ones?
- What would happen if we lost a crop variety?
- How do farmers learn about new crop varieties?
- How are harsh environmental conditions affecting crop varieties?
- Does FAO tell farmers which crop varieties to use?
Comprehensive, as I say. Even genebanks get a shout-out:
Crop variety loss also reduces the diversity of our cropping systems, thus making them more vulnerable to stresses. That’s why conservation is so important. By safeguarding inter- and intra-specific diversity of crops in genebanks and through on-farm management of diversity varieties are prevented from disappearing forever, their useful traits are documented, and this diversity remains available for the current and future generations. Conserved varieties are an essential resource for plant breeders, as they can be sources of important traits, such as stress resistance or nutritional quality, to be incorporated into new crop varieties.
Though I would personally have maybe included a nod to the potential direct role of genebanks in seed systems. Feeding breeding pipelines is surely not the only way genebanks can make an impact, especially for so-called neglected and underutilized crops — or opportunity crops as we should now call them I guess.
