- A primer on the USDA genebank in Pullman.
- Possible genebank in Indonesia. I could have sworn there was one already.
- Community genebank in Somalia. Surely not the only one.
- Garlic moves between genebanks. I’m sure there’s a reason.
- New enset products and processing methods are great, but is there a comprehensive genebank? I wish I could be sure.
- That goes for other “opportunity crops” and “forgotten foods” too.
How to revive your landraces
How can we help get humble heirloom varieties of the humble potato back into cultivation? Well, fortunately, Potato News Today 1 has a handy step-by-step guide, which I reproduce verbatim below:
- Start with a story you can legally sell. In Europe/UK, use the conservation-variety route; in North America, lean on certified seed suppliers and Indigenous stewardship agreements.
- Source clean, traceable stock. CIP and the U.S. Potato Genebank maintain indexed, disease-tested material; combine with reputable local seed houses.
- Pilot with chefs and specialty retail. Early-season launches with menu credit and a farm feature move the needle.
- Package the provenance. PDO/PGI examples like Jersey Royal and Papas Antiguas de Canarias show how origin, agronomy, and micro-harvest rituals create value.
- Engineer storage for shape and use. Follow the curing/holding guidance above.
- Ride the calendar. Tie launches and media to the International Day of Potato (30 May) or to local potato festivals.
Sounds pretty sensible, and applicable to other crops as well, I suspect, with a little tweak here and there.
The article also has a list of case studies. This doesn’t include any examples from Italy, but coincidentally a recent paper describes just such a thing. Which maybe points to something that is missing from the Potato News Today playbook, and that is having lots of interesting characterization and other data on your heirloom landraces handy to help get them ready for prime time.
Brainfood: Agroforestry, Afro-descendant conservation, Opportunity crops, Off-farm income, Phureja conservation, European taro, Argania products, Honeybee intensification, Mycorrhizal hotspots
- Effects of tree cover and crop diversity on biodiversity and food security in tropical agricultural landscapes. In tropical agricultural landscapes, modest tree cover in diverse cropping systems supports higher biodiversity and higher crop yields, demonstrating that agroforestry can deliver win-win synergy between conservation and food production.
- Afro-descendant lands in South America contribute to biodiversity conservation and climate change mitigation. I guess biodiverse landscapes managed according to traditional knowledge deliver superior environmental outcomes not just in farms with trees but also in forested territories under community management.
- Science for Africa’s future food security: reimagining the histories and futures of underutilised crops. Reviving indigenous, underutilised crops in sub-Saharan Africa by restoring their historical and cultural significance can enhance nutritional diversity, climate resilience and food security, paralleling the evidence above that culturally rooted, biodiversity-rich systems are good for both the environment and communities.
- Off-farm income and dietary diversity in subsistence farming in Burundi. Across rural and urban settings, from farms to forests to cities, culture-informed, biodiversity-rich food systems offer interlocking benefits: ecological resilience, climate mitigation, improved nutrition, and community empowerment. Or am I stretching a point here?
- Cultivar loss and conservation of genetic resources of the phureja potato (Solanum phureja L., Phureja Group) in Peru. Traditional Andean farming communities are witnessing the disappearance of this culturally significant diploid potato group, which has rich genetic diversity and interesting adaptations, highlighting an urgent need for in situ conservation to preserve it. Oh wow, look, locally rooted, biodiversity-rich farming systems, anchored in cultural heritage, are key to sustaining ecosystem services, safeguarding genetic diversity, and building climate-resilient, equitable food futures. Again.
- Taro (Colocasia esculenta) in Europe: a journey through fields, botanical gardens, ditches and city markets. This culturally important root crop was introduced in Europe in antiquity and now survives in fields, markets, and even city waterways as both ornament and food, but despite its genetic and cultural richness, it remains under-researched and requires both ex situ and in situ conservation to safeguard its long-term use. So yep, even this one says that conserving crop diversity through culturally embedded, multi-dimensional stewardship is essential for strengthening food security and preserving heritage in a changing climate.
- Innovation of argan (Argania spinosa (L.) Skeels) products and byproducts for sustainable development of rural communities in Morocco. A systematic literature review. Innovative uses of argan tree products and by-products in Morocco, from bioplastics and biochar to livestock feed and natural repellents, offer promising pathways for conservation, cultural preservation, and rural economic development, provided local communities are actively engaged in participatory management. Where have I heard that before?
- Negative ecological impacts of honeybees begin at densities below recommended levels for crop pollination. Too many honeybee hives can reduce wild bee abundance, species richness, and fruit yield on farms, even when wildflower strips are present, suggesting that ecological balance is disrupted when managed pollinators outcompete native species. Which can probably be cleverly connected with all of the above with a little more time than I have at the moment.
- Global hotspots of mycorrhizal fungal richness are poorly protected. What can I tell you, we need in situ conservation for mycorrhiza too. And machine learning can help us figure out where best to do it. For all of the above, and more, naturally.
Nibbles: COUSIN project, Breeding chat, Aardaker, Alternative beans, Grain amaranth, Iraqi seeds, Genebanks in peril
- The COUSIN project aims to conserve (trans situ, no less) and use crop wild relatives in Europe.
- That “use” part can be tough.
- But that doesn’t stop the fine people at Aardaia. At least where aardaker (Lathyrus tuberosus) is concerned.
- From alternative potatoes in the Netherlands to alternative beans in Indonesia. All in the cause of diversification.
- No need to find an alternative to amaranth in the American SW. Not with devoted chefs on the job.
- The Iraqi Seed Collective is taking seeds from American genebanks to that country’s diaspora in the US, and eventually back to Iraq itself. Maybe chefs will help.
- Good thing there are genebank backups, eh?
Brainfood: EcoregionsTreeFinder, Microbe niches, Herbarium phenology, Green Status Index of Species Recovery, Feral pigs, Trade & biodiversity, African cereal self-sufficiency, Plant protection, Ugandan seed systems, Grasspea breeding, Indigenous knowledge
- EcoregionsTreeFinder—A Global Dataset Documenting the Abundance of Observations of > 45,000 Tree Species in 828 Terrestrial Ecoregions. The right native tree for your ecoregion of choice. Which, given lots of the stuff below, is good to know. Oh, and BTW, there’s also the Agroforestry Species Switchboard.
- Modelling the distribution of plant-associated microbes with species distribution models. Would be cool to mash up with the above one day.
- The promise of digital herbarium specimens in large-scale phenology research. Something else you can use herbarium specimens for, if you’re careful.
- A global indicator of species recovery. The Green Status Index of Species Recovery, no less. Herbaria surely involved again.
- Valorization of feral pigs in the tropics, from the genetic characterization to the re- domestication. Wish there was a Green Status Index of Breed Recovery.
- Global staple food trade exacerbates biodiversity loss: a network perspective. Soybeans are messing with the Green Status Index of Species Recovery of lots of species, I suspect.
- Prospects for cereal self-sufficiency in sub-Saharan Africa. Prospects for self-sufficiency are not bad, but will require yield increases if the Green Status Index of Species Recovery is not going to take a hit.
- Protecting crops with plant diversity: Agroecological promises, socioeconomic lock-in, and political levers. Agroforestry and diverse landscapes are best for pest control, but cultivar mixtures are worth a try too. Wonder what they will do for cereal self-sufficiency in Africa. I lot, I bet, if given a chance.
- The dynamics of crop diversity and seed use in the context of recurrent climate shocks and poverty: Seasonal panel data evidence from rural Uganda. Farmers use crop diversity to cope with climate change, and wealthy farmers do it better. Pest control too, maybe?
- Understanding Farmer Preferences to Guide Crop Improvement: The Case of Grasspea in Ethiopia. Breeders should provide jam today and jam tomorrow.
