- Small farms contribute a third of the food consumed in high-income nations. And those small farms are disproportionately diverse…
- The Global Spatial Co-Variation Between Crop Diversity and Landscape Heterogeneity. …and crop diversity on farms goes with landscape diversity.
- Beyond Crop Hotspots: Why Overlooked Marginal Agricultural Lands Deserve Urgent Attention. I’m willing to bet landscape diversity is often associated with marginality, but that’s not the end of the world.
- Food Biodiversity and its Association with Diet Quality and Health Outcomes-A Scoping Review. Why should we care about diverse farms? Because diversity in your food is associated with nutritional adequacy, a reduced risk of mortality, or a reduced risk of gastrointestinal cancers. Ok, I know, I missed a step there. There was nothing in the past few weeks in the literature specifically linking farm diversity and food diversity, but you know the link is there. At least sometimes.
- Long-term agricultural diversification increases financial profitability, biodiversity, and ecosystem services: a second-order meta-analysis. Diversity on farms is not just good for (ok, maybe) diets.
- Global evidence that plant diversity suppresses pests and promotes plant performance and crop production. Another way farm diversity is useful is via pest control. Well, actually, this could count as an ecosystem service, and so an example of the above.
- Ecological drivers of intercropping performance for enhanced global crop production. Ah, that explains how those farm ecosystem services actually works.
- Crop rotations synergize yield, nutrition, and revenue: a meta-analysis. Rotations are diversification too, and good for you too.
- Revitalizing orphan crops to combat food insecurity. But of course the diversification strategy de jour is opportunity crops.
- Value chain research and development: The quest for impact. And for that revolution to happen, we’ll need a better grip on value chains.
- Cultural innovation can increase and maintain biodiversity: A case study from medieval Europe. Yes, agricultural revolution can lead to increased biodiversity.
- Household vegetable agro-biodiversity in northern Vietnam requires diversity in seed sources. Any revolution is going to need good sources of good seeds though.
Brainfood: Agroecology, Afghan wheat, CWR microbes, Chocolate microbes, Liberica coffee, Wild apples, USDA cotton collection, Parmesan cattle, Sweetpotato genome, Vertical tomatoes
- Embracing new practices in plant breeding for agroecological transition: A diversity-driven research agenda. Plant breeding for agroecology will need access to locally-adapted plant diversity, sure, but also the involvement of a diversity of stakeholders and the use of a diversity of co-design strategies.
- Conservation and Utilization of Wheat Genetic Resources in Afghanistan Expanded with the Homecoming Wheat Landraces Collected Half a Century Ago. The above could also be said of wheat breeding in Afghanistan. Fingers crossed.
- Blueprints for sustainable plant production through the utilization of crop wild relatives and their microbiomes. Oh, wait, breeders (agroecological and otherwise) will also need the diversity of microbiomes associated with crop wild relatives.
- A defined microbial community reproduces attributes of fine flavour chocolate fermentation. Oh, wait, we will also need the diversity of the microbes involved in fermentation, at some point.
- Genomic data define species delimitation in Liberica coffee with implications for crop development and conservation. It might help if we knew how many species made up a crop in the first place. In the case of Liberica coffee, it turns out to be 3. No word on the microbiomes involved.
- Assessment of genetic diversity and population structure of Malus sieversii and Malus niedzwetzkyana from Kazakhstan using high-throughput genotyping. It would also help to know where interesting diversity was concentrated within crop wild relatives. In apples, it’s not necessarily the ancestor.
- The National Plant Germplasm System cotton collection—a review of germplasm resources, phenotypic characterization, and genomic variation. Lots of morphological characterization and agronomic evaluation, not so much molecular data, but increasing. No word on the microbes.
- Establishing a genomic-driven conservation of a cattle genetic resource: the case of the Parmigiano-Reggiano cheese iconic breed. In contrast, these guys have genotyped practically a whole breed. But yeah, no microbes.
- Phased chromosome-level assembly provides insight into the genome architecture of hexaploid sweetpotato. The contributions of different wild relatives to the sweetpotato genome are to be found intertwined along chromosomes rather than restricted to subgenomes. Unclear what that will mean to agroecologial breeders.
- Harnessing Green Revolution genes to optimize tomato production efficiency for vertical farming. Agroecological breeders unavailable for comment.
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.

- 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.
- Crop diversity trends captured by Indigenous and local knowledge: introduction to the symposium. Indigenous and local knowledge can help you keep track of all of the above.
Nibbles: Cherokee Three Sisters, Australian native grains, Ancient Peruvian irrigation, Indian apples, IFOAM Seed Platform, MSB, Chinese conservation, Protected areas, Soybeans breeding, Funding cuts
- Three Sisters rematriated to historical Cherokee Nation.
- Native grains returning to Indigenous land in Australia too.
- May need to bring back agricultural practices too, like in Peru.
- Meanwhile, in India, farmers are trying to grow apples in new places. Go figure.
- Anyway, seems like the IFOAM Seeds Platform might be able to help.
- And genebanks too of course, like the Millennium Seed Bank.
- As part of a comprehensive conservation systems, goes without saying, like in China.
- Which also include climate-proof protected areas.
- It worked for soybeans, after all.
- Well, for now anyway…
