- Plant diversity modifies multi-trophic interactions in croplands, grasslands and forests. Increasing plant diversity changes the interactions between plants, herbivores and their natural enemies, but exactly how depends on the ecosystem. Diversification’s pest-suppression magic looks like a farming-specific trick, not a universal law.
- High-resolution carbon and biodiversity mapping shows correlated losses across space and agricultural products. Carbon loss and biodiversity loss from farming turn out to hit the same ground: two-thirds of both concentrated on one-third of agricultural land, with beef and milk alone responsible for 41% of the biodiversity damage. Good news for anyone hoping one policy lever could do double duty.
- Harnessing agri-food system microbiomes for sustainability and human health. Soil to gut, it’s all one network, linking ecosystem function, food production and human health across the entire agri-food system.
- Breeding for beneficial microbial associations. If microbiomes matter that much, why not breed for them? A proposed framework pairs crop traits that recruit good microbes (root exudates, architecture) with soil practices that keep those microbes around, since good genetics on ruined soil gets you nowhere. This means designing crops as participants in ecological networks rather than as isolated organisms.
- Host genetics and social relationships jointly shape fitness-associated microbiome variation in a population of feral horses. Nature’s own microbiome-breeding program: seven years of horse poop from Sable Island shows gut microbes predict winter survival, and related horses share microbes more than chance allows. So the functional unit of adaptation is the animal plus its microbiome.

We’re moving house so this might be the last post for a while. See you on the other side. In the meantime, enjoy this bunch of papers on different applications of spatial analysis to agricultural biodiversity and associated topics.
- Addressing global hotspots of drought-related crop production losses. A crop-specific drought sensitivity metric for 17 major crops finds rainfed production losses of 10% globally under historically observed extremes, enough to feed 2 billion people, with hotspots in the US Midwest, eastern Brazil, the Mediterranean and South Asia. Sustainable irrigation expansion and crop switching could avoid 60% of those losses. No word on varietal change, but I’m sure it would help.
- GEM-Forest: A Global satellite EMbedding–based map of forests and tree crops for 2020. Using Google DeepMind’s Alpha Earth Foundation embeddings, this 10 m global dataset classifies forest, non-forest and tree crop areas with 90% accuracy, showing that lightweight classifiers on satellite embeddings 1 can rival more complex forest-monitoring pipelines built to support things like the EU Deforestation Regulation.
- Global distribution of cattle, horses, goats, sheep and buffaloes at 1 km resolution for 2000–2022 based on subnational census data and spatiotemporal machine learning. Harmonizing 55,336 census polygons across 147 countries produces annual 1 km livestock headcount and density layers for five species, letting users track shifting grazing pressure over more than two decades rather than relying on single-year snapshots. 2
- A Spatial-Econometric Analysis of Fruit Tree Diversity in Lebanon: A contextual framework for supporting smallholder farmers. How geography, socio-economic conditions and local context shape fruit tree diversity in Lebanon, helping identify where interventions could best support smallholder resilience.
- High-resolution mapping of rice cropping pattern, intensity, calendar, and ecosystem type across Southeast Asia. Joins the growing pile of fine-resolution rice products for the region, this one distinguishing not just how many harvests a field gets but which rice ecosystem (irrigated, rainfed, upland) it belongs to. Is which variety is being grown next on the agenda?
- Entrenchment of cropping patterns reinforces climate exposure for certain crops in US. County-level analysis of US cropping decisions finds that climate risk has actually risen for some crops (like rainfed soybeans) even as it fell for others, suggesting economic and policy incentives are keeping farmers planted in increasingly climate-mismatched patterns rather than nudging them toward the drought-sensitivity-driven switching the first paper above models.
Nibbles: Kenyan crops, Omani mangoes, Wheat mixtures, Wagyu origins
- Kenyan farmers are rediscovering indigenous crops.
- Oman discovers it has lots of mango diversity, and moves to conserve it.
- Swedish student discovering varietal mixtures.
- Discover how a locally adapted cattle population in Japan became a globally recognized premium brand by maintaining distinctive genetic and breeding characteristics. Lessons there for all of the above perhaps?
Brainfood: Animal genetic resources
- Beyond the binary: Queer inclusion and invisible labour in Samoa’s fisheries value chains. Fisheries in Samoa depend on significant but largely unrecognized labour by LGBTQ+ people, particularly fa’afafine and fa’afatama, whose contributions are overlooked by policies based on rigid gender categories.
- Genetic and morphological diversity of indigenous chicken of Kenya: A Review. Kenya’s indigenous chickens are adapted to diverse environments, resilient to disease, and important for rural livelihoods.
- Uncovering the lives of rock doves (Columba livia) in Late Bronze Age Hala Sultan Tekke, Cyprus. Rock doves lived alongside people in a major Late Bronze Age port city, revealing a more complex relationship than simple domestication in which doves exploited urban environments while providing food and other resources.
- Farmed Escapees Threaten MHC Diversity in Wild Atlantic Salmon. Escaped farmed Atlantic salmon can erode the diversity of major histocompatibility complex (MHC) genes in wild populations through interbreeding, which could reduce the long-term resilience and adaptability of wild salmon.
- Creation of intermuscular bone-free genetic mutants in grass carp and multiomics reveals molecular regulatory basis. Genome editing was used to produce grass carp lacking the numerous fine intermuscular bones that reduce consumer appeal, opening new possibilities for breeding more marketable fish while deepening understanding of skeletal biology.
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.
