- Consistent stabilizing effects of plant diversity across spatial scales and climatic gradients. More species-diverse communities are more stable. Ok, what about agricultural systems though?
- Financial profitability of diversified farming systems: A global meta-analysis. Total costs, gross income and profits were higher in diversified systems, and benefit-cost ratio similar to simplified systems. No word on stability, alas.
- Global systematic review with meta-analysis reveals yield advantage of legume-based rotations and its drivers. Integrating a legume into your low-diversity/low-input cereal system can boost main crop yields by 20%. I wonder if this meta-analysis was included in the above meta-analysis. Again, no word on stability though.
- The influence of food environments on dietary behaviour and nutrition in Southeast Asia: A systematic scoping review. It’s the affordability, stupid. Should have gone for more diversified farming I guess :)
- Global food systems transitions have enabled affordable diets but had less favourable outcomes for nutrition, environmental health, inclusion and equity. Well according to this, industrialised farming (ie simplification) has led to more affordable diets. But we know from the above that diversification can be profitable. So it was the wrong kind of simplification? Can we diversify now and maintain affordability while also improving nutrition, environmental health, inclusion and equity? Wouldn’t that be something.
- Disentangling the numbers behind agriculture-driven tropical deforestation. Ending deforestation is not enough. The resulting agriculture must be diversified in the right way too, I guess.
- Strategizing research and development investments in climate change adaptation for root, tuber and banana crops in the African Great Lakes Region: A spatial prioritisation and targeting framework. Diversifying with drought-tolerant bananas and heat-tolerant potatoes is all well and good, but you also have to know where exactly to diversify, and here’s how.
- Translational research in agriculture. Can we do it better? Difficulty developing drought-tolerant bananas and heat-tolerant potatoes? Get more diverse peer-reviewers.
- Increasing crop field size does not consistently exacerbate insect pest problems. When you diversify, don’t worry too much about making fields bigger.
- Genetic diversity loss in the Anthropocene. You can predict change in genetic diversity from change in range size, and the average is about a 10% loss already. Ok, what about agricultural systems though? Wait, isn’t this where we came in? My brain hurts…
Brainfood: GIAHS, Austronesian ag, Neolithic Scotland, Livestock origins, Iroquoia maize, Maya drought, Agave diversity, Coffee diversity, Breadfruit cultivation
- Agricultural heritage systems and agrobiodiversity. FAO’s Globally Important Agricultural Heritage Systems (GIAHS) work just fine.
- A northern Chinese origin of Austronesian agriculture: new evidence on traditional Formosan cereals. The precursors of the Austronesians took foxtail millet, broomcorn millet and rice to Taiwan from around Shandong in northeastern China in the second half of the 4th millennium BCE. That was quite a globally important agricultural heritage system (note lower case) in its day.
- Neolithic culinary traditions revealed by cereal, milk and meat lipids in pottery from Scottish crannogs. At roughly the same time as the above, farmers in Scotland were eating a gruel made of wheat and milk. Maybe not so globally important, but still.
- Epipalaeolithic animal tending to Neolithic herding at Abu Hureyra, Syria (12,800–7,800 calBP): Deciphering dung spherulites. That wheat and milk came from far away and long ago. In fact, maybe 2000 years longer ago than is usually thought.
- Tracing Maize History in Northern Iroquoia Through Radiocarbon Date Summed Probability Distributions. Maize really took off in NY/Ontario/Quebec between 1200 and 1450 AD.
- Drought-Induced Civil Conflict Among the Ancient Maya. Towards the end of the above period there was real strife in the Maya lands, but also local resilience. Makes you wonder whether whatever was happening among the Iroquois and Maya was somehow connected.
- Genomic and Morphological Differentiation of Spirit Producing Agave angustifolia Traditional Landraces Cultivated in Jalisco, Mexico. Whatever happened in Mesoamerica 600 years ago, Indigenous knowledge of agave diversity survived.
- Vernacular Names and Genetics of Cultivated Coffee (Coffea arabica) in Yemen. Indigenous knowledge of coffee diversity doesn’t correspond with genetic data in this globally significant agricultural heritage system.
- Advanced and emerging agricultural innovations for securing food, climate and ecosystems in Moroccan oasis. Even globally important agricultural heritage systems need innovation.
- Potential of breadfruit cultivation to contribute to climate-resilient low latitude food systems. Breadfruit can be important globally, not just in its current agricultural heritage system.

- Constructing Seed Boundaries: Foundation and Evolution of Scientific Conceptions and Practices of Crop Diversity from the Green Revolution to date. We need to put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Open Source Seeds and the Revitalization of Local Knowledge. Open-source seeds is one way we can put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Evaluation of Global Composite Collection Reveals Agronomically Superior Germplasm Accessions for Chickpea Improvement. We need detailed, multi-location, multi-year agronomic evaluation of chickpea diversity to figure out what diversity we should use to give farmers the diversity we think they will need.
- Home gardens of Central Asia: Reservoirs of diversity of fruit and nut tree species. We need homegardens.
- Data-driven, participatory characterization of farmer varieties discloses teff breeding potential under current and future climates. We need detailed, multi-location, multi-year agronomic evaluation of teff diversity done in collaboration with farmers to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Cultural Effects on Sorghum Varieties Grown, Traits Preferred, and Seed Management Practices in Northern Ethiopia. We need detailed, multi-location, multi-year studies of farmers’ sorghum diversity, practices and needs to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Metrics for optimum allocation of resources on the composition and characterization of crop collections: The CIMMYT wheat collection as a proof of concept. We could use genotyping and this fancy maths to figure out what to have in our wheat genebank collections so we can then figure out which diversity to use to give farmers the diversity we think they will need.
- From marginalized to miracle: critical bioregionalism, jungle farming and the move to millets in Karnataka, India. Forget wheat. We need local food activism. But critical local food activism.
- G-DIRT: a web server for identification and removal of duplicate germplasms based on identity-by-state analysis using single nucleotide polymorphism genotyping data. We need this fancy software to get rid of duplicates from our genebank collections so it’s cheaper to maintain them and ensure that they’re always around for people to use to get to farmers the diversity they need.
- “Famine Foods” and the Values of Biodiversity Preservation in Israel-Palestine. We need recipes.
Brainfood: Species mixtures double, Crop diversification, Local adaptation, Speed of adaptation, Essential Biodiversity Variables, Effective population size, Monitoring diversity
- Drought-exposure history increases complementarity between plant species in response to a subsequent drought. Repeated stress makes plant species get along better, sustaining diversity. If only it worked so well with people…
- A quantitative synthesis of soil microbial effects on plant species coexistence. Meta-analysis shows soil microbes work against plant species getting along better.
- Does crop diversification lead to climate-related resilience? Improving the theory through insights on practice. Crops getting along well together is pretty well linked to better livelihoods, but less strongly to increased resilience.
- Local Adaptation: Causal Agents of Selection and Adaptive Trait Divergence. You need to do reciprocal transplant experiments really well to find out where plants are best adapted and why. Probably means taking microbes into account.
- Genetic variance in fitness indicates rapid contemporary adaptive evolution in wild animals. Natural selection can be quicker than climate change. I hope they did the reciprocal transplant experiments really well.
- Global genetic diversity status and trends: towards a suite of Essential Biodiversity Variables (EBVs) for genetic composition. Genetic diversity, Genetic differentiation, Inbreeding, and Effective Population Size (Ne). Who needs reciprocal transplant experiments?
- On the feasibility of estimating contemporary effective population size (Ne) for genetic conservation and monitoring of forest trees. Ouch.
- Selecting species and populations for monitoring of genetic diversity. All of them, right?
Brainfood: Diversity & breeding in Coix, Triticum, Phaseolus, Manihot, Oryza, Vigna, Glycine, Zea, Malus
- Nutritional profiling and GIS-based grid mapping of Job’s tears (Coix lacryma-jobi L.) germplasm. 2 genebank accessions out of 32 are especially good.
- Diversity and Adaptation of Currently Grown Wheat Landraces and Modern Germplasm in Afghanistan, Iran, and Turkey. Some wheat landraces were just as productive as modern varieties, so crossing landraces with other landraces could be a good breeding strategy. Maybe even for Job’s tears.
- Mining of the national gene bank collection identifies resistance sources for loose smut of wheat in Northern Himalayan conditions. 58 of 586 were resistant. Let the inter-landrace crossing begin!
- Are Traditional Lima Bean (Phaseolus lunatus L.) Landraces Valuable to Cope with Climate Change? Effects of Drought on Growth and Biochemical Stress Markers. Oh no, the commercial variety is more drought-resistant than the, ahem, two landraces.
- Low-cost, handheld near-infrared spectroscopy for root dry matter content prediction in cassava. A faster and cheaper way of figuring out which cassavas are better than others.
- Mutations in DNA polymerase δ subunit 1 co-segregate with CMD2-type resistance to Cassava Mosaic Geminiviruses. Now for a faster and cheaper way of spotting the gene in your crosses.
- Phenotypic Variation and the Impact of Admixture in the Oryza rufipogon Species Complex (ORSC). Sometimes there’s no short-cut to the slog of detailed phenotyping if you want a short-cut to pre-breeding.
- Evaluation of black gram varieties using crowd source citizen science under northern hilly climatic condition of Chhattisgarh. Let the farmers do the slog of phenotyping.
- A view of the pan-genome of domesticated cowpea (Vigna unguiculata [L.] Walp.). The genes not shared by all six sub-populations of the cultivated cowpea are very important to the overall diversity of the crop. Let scientists do the slog of genotyping.
- Breeding for disease resistance in soybean: a global perspective. 800 resistance loci/alleles for 28 varied diseases from all over the world. Imagine one variety with all of them :)
- Genetic diversity in early maturity Chinese and European elite soybeans: A comparative analysis. Two equally diverse but distinct genepools. Unclear how the above 800 loci divide up.
- Association mapping across a multitude of traits collected in diverse environments in maize. More slogging through phenotyping, this time to uncover pleiotropy.
- Incorporating male sterility increases hybrid maize yield in low input African farming systems. But I guess you need the above to decide on the parents for your fancy hybrids.
- Pedigree reconstruction for triploid apple cultivars using single nucleotide polymorphism array data. Triploids apples may be bigger and stronger, but they’re also genetic dead ends.
- Evidence of an additional center of apple domestication in Iran, with contributions from the Caucasian crab apple Malus orientalis Uglitzk. to the cultivated apple gene pool. Another example of multiple domestication “events”.
