- Germplasm Acquisition and Distribution by CGIAR Genebanks. A lot of stuff going in, a lot of stuff coming out, to everyone’s benefit. 35 years of data, with special focus on the last 10.
- Intraspecific diversity as a reservoir for heat-stress tolerance in sweet potato. 132 out of 1973 accessions tolerant of heat, though in different ways. A prime example of the above benefits.
- Identification and characterization of high‐yielding, short‐duration rice genotypes for tropical Asia. Short-duration varieties will need to be a bit taller and leafier to yield more. Another example of the above benefits.
- Modelled distributions and conservation priorities of wild sorghums (Sorghum Moench). More stuff needs to go into the above genebanks, though, for example from N. Australia.
- Ex situ and in situ conservation gap analysis of crop wild relative diversity in the Fertile Crescent of the Middle East. Same from the Fertile Crescent.
- In situ and ex situ conservation gap analyses of crop wild relatives from Malawi. And not just the above genebanks either.
- The Potential of Payment for Ecosystem Services for Crop Wild Relative Conservation. Ok, we have the gaps (see above), and now here we have the method. What’s stopping us?
- Assessing under-Estimation of Genetic Diversity within Wild Potato (Solanum) Species Populations. Wild diploid species more diverse than previously thought. So providing more ecosystem services?
- Genetic diversity and differentiation of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. in the Hajar Mountains of Oman. No word on the ecosystem services being provided.
- The investigation of minor and rare Tunisian olive cultivars to enrich and diversify the olive genetic resources of the country. Rare + minor doesn’t mean bad. But maybe an influx of Omani genes would help?
- Biobanking of vegetable genetic resources by in vitro conservation and cryopreservation. Yes, even for vegetables.
- From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection. Four subpopulations: Calabrese broccoli landraces, hybrids, sprouting broccoli, and violet cauliflower. Diversity in modern varieties decreasing with time.
- Crop switching reduces agricultural losses from climate change in the United States by half under RCP 8.5. But it will have to be a lot of switching. Hopefully out of broccoli.
- The mosaic genome of indigenous African cattle as a unique genetic resource for African pastoralism. An influx of zebu genes about a thousand years ago is responsible for the success of African pastoralism.
- Protection of traditional agricultural knowledge and rethinking agricultural research from farmers’ perspective: A case from Turkey. Against power imbalances the gods themselves contend in vain.
Brainfood: Dietary diversity, Farm diversity double, Neolithic dairy, Exotic breeds, Yam viruses, Cassava GWAS, Satellite phenotyping, Forest restoration & disturbance, Genetic rescue, Budwood cryo, SP cryo, Dry grasslands, Botanical gardens, Remote sensing
- Agricultural Food Production Diversity and Dietary Diversity among Female Small Holder Farmers in a Region of the Ecuadorian Andes Experiencing Nutrition Transition. Higher diversity of crops on family farms is only weakly associated with greater dietary diversity and lower household food insecurity among female caretakers. Better than nothing, though, right?
- Productive Capacity of Biodiversity: Crop Diversity and Permanent Grasslands in Northwestern France. Having a bigger percentage of permanent grassland on your French farm, or a greater diversity of crops, can increase cereal and milk yields. No word on diets.
- The influence of landscape composition and configuration on crop yield resilience. No effect on yield per se (see above), but proximity to semi-natural habitat does increase yield stability in UK farms.
- Living off the land: Terrestrial-based diet and dairying in the farming communities of the Neolithic Balkans. Ancient farmers had a varied diet, but possibly not involving consumption of raw milk, at least by adults.
- Food securers or invasive aliens? Trends and consequences of non-native livestock introgression in developing countries. In 40 countries, the proportion of livestock populations belonging to local breeds has been decreasing by about 1% a year for the past 20 years. Hey, but milk yield per cow has been going up, so there’s that.
- Potentials of Cultivated Varieties and Wild Yam Seeds as Efficient Alternative Plant Genetic Resources for Resistant Genotypes against Yam Mosaic Virus (YMV) in Togo. Work with seeds! But were they properly inoculated? Hopefully a virologist will tell us.
- Genome-wide association analysis reveals new insights into the genetic architecture of defensive, agro-morphological and quality-related traits in cassava. Lots of interesting markers for cassava breeders, or at least those working with material from W Africa. Do it for yams next?
- High-resolution satellite imagery applications in crop phenotyping: An overview. Clouds, you say? Not a problem any more. But can it distinguish landraces from modern varieties? What’s needed is a sort of mutant algorithm, I guess.
- Crop type identification and spatial mapping using Sentinel-2 satellite data with focus on field-level information. Still some way from being able to distinguish landraces from modern varieties, I see.
- Global forest restoration and the importance of prioritizing local communities. I’m shocked I tell you, shocked.
- Protection gaps and restoration opportunities for primary forests in Europe. A lot of restoration could usefully be done in currently protected areas, though it would be better if these were expanded. No word on local communities.
- Mapping the forest disturbance regimes of Europe. I guess this means that restoration, when it happens, will be monitored from space.
- Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation. When you do do restoration, don’t worry about genetic pollution, just go for as much diversity as possible. Well, for small relict populations. Of animals.
- Considerations for large-scale implementation of dormant budwood cryopreservation. It’s about the logistics.
- Development of a fast and user-friendly cryopreservation protocol for sweet potato genetic resources. It’s the axillary meristems. Among other things.
- The human–environment nexus and vegetation–rainfall sensitivity in tropical drylands. Dryland grasslands in Africa and Asia less able to respond to water availability overall, more able in Australia and S America, evens stevens in N America. Would be interesting to mash up particularly hard-hit areas with CWR and forage germplasm collecting localities.
- Botanic garden solutions to the plant extinction crisis. Expertise, tools, facilities, and networks are there. You know what’s missing, right?

- Projected temperature increases may require shifts in the growing season of cool-season crops and the growing locations of warm-season crops. In California’s Mediterranean climate, cool season crops will have to shift in time, and warm-season crops in place.
- A “Mega Population” of the Wild Potato Species Solanum fendleri. Large population, safe, accessible and very diverse. Who needs genebanks, right?
- Survival of Solanum jamesii Tubers at Freezing Temperatures. Very unusual trait in both the crop and the wild relatives, apparently.
- Diversity and uses of enset [Ensete ventricosum (Welw.) Cheesman] varieties in Angacha district, Southern Ethiopia: call for taxonomic identifications and conservation. 55 varieties in 75 homegardens, 88 in the field genebank, many in only one or the other.
- Impact of Climate Change on the Diversity and Distribution of Enset (Ensete ventricosum (Welw) Cheesman) in Ethiopia: A Review. Some are moving, some are dying. I guess we really need in vitro and cryo after all.
- Filling the gaps in gene banks: Collecting, characterizing and phenotyping wild banana relatives of Papua New Guinea. Much diversity of banana ancestor still not in genebanks, but people are on the job.
- Modeling the Impact of Crop Diseases on Global Food Security. Genetic diversity is not enough.
- What natural variation can teach us about resistance durability. That genetic diversity is not enough, apparently.
- Wheat blast: a new threat to food security. We have the genes to fight it, but they won’t be enough.
- Limited haplotype diversity underlies polygenic trait architecture across 70 years of wheat breeding. I hope at least those genes can be found in this MAGIC population based on European bread wheat varieties from the past few decades.
- Potential Short-Term Memory Induction as a Promising Method for Increasing Drought Tolerance in Sweetpotato Crop Wild Relatives [Ipomoea series Batatas (Choisy) D. F. Austin]. Wild sweet potatoes have the genes to remember drought stress, and hence cope with it better. Will they be enough though?
- Ecological pest control fortifies agricultural growth in Asia–Pacific economies. Biological control has been worth USD 15-20 billion a year for non-rice crops over the past 100 years across 23 countries. But how much is the interaction with genetic diversity worth?
- Evaluation of the contribution of teosinte to the improvement of agronomic, grain quality and yield traits in maize (Zea mays). Wild relative not just a source of stress resistance, could be useful for yield potential too.
- “It may also have prevented churchgoers from falling asleep”: southernwood, Artemisia abrotanum L. (fam. Asteraceae), in the church bouquet, and its contemporary presence as a heritage plant in Sweden. The fragrance lingers.
- Multiple cropping systems of the world and the potential for increasing cropping intensity. Multiple cropping on 12% of total agricultural area, which could increase, but probably not as much as was thought.
- Impact and returns on investment of mungbean research and development in Myanmar. Four varieties coming out of international research created economic gains of USD 1.4 billion from 1980-2016. That’s a ROI of about 90, but it took 20 years to kick in.
- Are Traditional Food Crops Really ‘Future Smart Foods?’ A Sustainability Perspective. Well, they could be, but maybe we don’t have 20 years.
- New Guinea highland wild dogs are the original New Guinea singing dogs. …which are therefore not extinct in the wild as used to be thought. Or so the DNA says.
- WEGE: A new metric for ranking locations for biodiversity conservation. That’s “Weighted Endemism including Global Endangerment,” and it hasn’t been tried on plants. Yet.
- Toward Unifying Global Hotspots of Wild and Domesticated Biodiversity. They overlap a lot but not completely. Expect WEGE to be applied at some stage.
Brainfood: Bending the curve edition
- Bending the curve of terrestrial biodiversity needs an integrated strategy. Meaning: (i) sustainable agricultural intensification, (ii) trade, (iii) less food waste, (iv) more plant-based human diets, and (v) more and better protected areas.
- The carbon opportunity cost of animal-sourced food production on land. See (iv) above.
- Just ten percent of the global terrestrial protected area network is structurally connected via intact land. See (v) above.
- Cropland expansion in the United States produces marginal yields at high costs to wildlife. See (i) above.
- A cultivated planet in 2010 – Part 1: The global synergy cropland map. Gotta know where the cropland is before you can do (i) above.
- Advances in plant phenomics: From data and algorithms to biological insights. Fancy maths can really help with (i) above.
- Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields. Different fancy maths shows that CIMMYT’s Obregon wheat testing site can really help with (i) above.
- Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints. Here’s some stuff that wheat breeders can use to develop new materials to test at Obregon using phenomics, genomics and fancy maths.
- First report on cryopreservation of mature shoot tips of two avocado (Persea americana Mill.) rootstocks. This should help with (iv) above. Eventually, work with me here.
- Bread and porridge at Early Neolithic Göbekli Tepe: A new method to recognize products of cereal processing using quantitative functional analyses on grinding stones. Ahem. Well… No, sorry, I got nothing.
Brainfood: Special citizen science edition
Something for the weekend. I hope you enjoy this special edition of Brainfood focusing on citizen science, Indigenous knowledge and participatory research. Do you like themed Brainfood editions like this? There will be another one on Monday, as it happens. They’re more tricky to produce, but if there’s significant interest I may make the extra effort. Let me know, and suggest topics.
- The value of climate-resilient seeds for smallholder adaptation in sub-Saharan Africa. Up to USD 2 billion in Malawi and Tanzania over the next 30 years.
- Agricultural productivity and deforestation: Evidence from input subsidies and ethnic favoritism in Malawi. Cheaper fertilizers increased yields and decreased deforestation. Better seeds would help too, no doubt (see above).
- Channels used to deliver agricultural information and knowledge to smallholder farmers. Farmer groups and demonstration plots work well to spread the news about fertilizers and seeds.
- Integrating Conventional and Participatory Crop Improvement for Smallholder Agriculture Using the Seeds for Needs Approach: A Review. Combine high-tech centralized and participatory decentralized germplasm evaluation and breeding approaches to get those better seeds to farmer groups and their demonstration plots.
- Citizen science breathes new life into participatory agricultural research. A review. Why do the participatory, decentralized bit? Here’s why. Fortunately, there’s an app for it…
- A global resource for exploring and exploiting genetic variation in sorghum crop wild relatives. If those seeds include sorghum, you could start with this lot.
- Gendered differences in crop diversity choices: A case study from Papua New Guinea. And don’t forget gender as you do all this participatory, decentralized stuff. For example, in PNG, the women are into marketing, the men into tradition.
- Crowd breeding of Danish apple cultivars. No word on gender differences, alas.
- Modelling illustrates that genomic selection provides new opportunities for intercrop breeding. Here’s the high-tech, centralized bit, or at least a model of it, ripe for mashing up with citizen science.
- Dissection of the domestication‐shaped genetic architecture of lettuce primary metabolism. More high-tech, centralized stuff, the real thing this time. Which can now be used to breed a better lettuce, hopefully by lots of citizens growing the stuff in their gardens and providing salad tasting results through a nifty app.
- Indigenous and Local Knowledge Practices and Innovations for Enhancing Food Security Under Climate Change: Examples from Mijikenda Communities in Coastal Kenya. Maybe farmers should run participatory programmes, with scientists as the citizens.
- Micronutrient composition and microbial community analysis across diverse landraces of the Ethiopian orphan crop enset. Don’t know how you’d do citizen science on this, but I bet somebody does.
- Discovering the indigenous microbial communities associated with the natural fermentation of sap from the cider gum Eucalyptus gunnii. Someone mention traditional fermentation practices?
- The Milpa Game: a Field Experiment Investigating the Social and Ecological Dynamics of Q’eqchi’ Maya Swidden Agriculture. Citizen science is not a game. No, wait…
- The Ancient Tree Inventory: a summary of the results of a 15 year citizen science project recording ancient, veteran and notable trees across the UK. Not a game indeed: very serious, but fun, definitely fun.
