- Conservation needs to break free from global priority mapping. Couldn’t agree more. And less.
- National climate and biodiversity strategies are hamstrung by a lack of maps. Wait, what?
- The evolutionary genomics of species’ responses to climate change. You need to combine niche modelling with genetic adaptation to get the best maps.
- Payoffs to a half century of CGIAR research. A benefit-to-cost ratio (BCR) of 10:1. Not counting the genebanks. And all the maps.
- A case for conserving plant pathogens. But will it be worth it?
- Poor data stewardship will hinder global genetic diversity surveillance. What’s the BCR for decent metadata?
- Mitigating tradeoffs in plant breeding. Cutting out the cross-talk changes tradeoff to payoff.
- Comparing Productivity of Organic and Conventional Farming Systems: A Quantitative Review. Conventional is more productive. But should yield be the only criterion?
- Priority micronutrient density in foods. Right. Micronutrients are also important.
- Reconciling yield gains in agronomic trials with returns under African smallholder conditions. And how was yield measured anyway?
- Data-driven, participatory characterization of traditional farmer varieties discloses teff (Eragrostis tef) adaptive and breeding potential under current and future climates. This might well be an example of applying the lessons of the above.
- Genetic Diversity and Utilization of Cultivated Eggplant Germplasm in Varietal Improvement. The wild relatives will save us.
- Quinoa Phenotyping Methodologies: An International Consensus. But will it work for the wild relatives? Just kidding, this is an important development for another crop (with the above) which doesn’t have something like the CGIAR and its 10:1 BCR behind it…
Nibbles: Genebanks in Brazil, Tunisia, Ghana, Ethiopia, Goan rice, Wheat adoption, Peruvian hot peppers & cacao, Amazonian fruits and nuts, Dates, Great Hedge of India, Conservation genetics presentation
- Safety duplicating a chickpea collection.
- Tunisia’s genebank in the news.
- Ghana’s genebank trying to save taro.
- Using a genebank to improve Elephant grass.
- On-farm conservation of rice in Goa.
- Molecular tools show that a couple of varieties account for about half the wheat acreage in Bangladesh and Nepal. Hope all the landraces are in genebanks, and safety duplicated.
- Celebrating Peruvian pepper diversity.
- Peru’s cacao diversity doesn’t need help, apparently.
- However, the Amazon’s wild-extracted fruits (including cacao and a wild relative) could be in trouble. Hope they’re in genebanks, just in case.
- How the date came to the US. Including its genebanks.
- India had a precursor of the Green Wall of Africa but nobody remembers it. Glad it wasn’t used as a genebank of sorts.
- Conservation genetics (i.e., most of the above) explained in 48 slides.

- Extreme climate events increase risk of global food insecurity and adaptation needs. Factoring in climate variability shows that just considering the change in the average climate underestimates the food security hit.
- Increases in extreme heat stress in domesticated livestock species during the twenty-first century. And the hit is already landing.
- Data-driven decentralized breeding increases prediction accuracy in a challenging crop production environment. What we therefore need is 3-D breeding.
- Novel Sources of Pre-Harvest Sprouting Resistance for Japonica Rice Improvement. Including for resistance to pre-harvest sprouting in rice due to unexpected typhoons.
- The genome of stress tolerant crop wild relative Paspalum vaginatum leads to increased biomass productivity in the crop Zea mays. For sure crop wild relatives are going to help.
- Megabase-scale presence-absence variation with Tripsacum origin was under selection during maize domestication and adaptation. If they haven’t helped already.
- Registration of three peanut allotetraploid interspecific hybrids resistant to late leaf spot disease and tomato spotted wilt. Sometimes you need multiple CWR.
- Collection, genotyping and virus elimination of cassava landraces from Tanzania and documentation of farmer knowledge. But landraces too will come in handy, especially if farmers’ knowledge is properly documented.
- Prioritizing host phenotype to understand microbiome heritability in plants. And don’t forget the microbiome.
- Economic analysis of habitat manipulation in Brassica pest management: Wild plant species suppress cabbage webworm. Not to mention the ecosystem as a whole.
- Relevance of hop terroir for beer flavour. Oh hell, I give up, time for a craft beer.
- On the Trail of the German Purity Law: Distinguishing the Metabolic Signatures of Wheat, Corn and Rice in Beer. Maybe even a weissbier.
The Economist on investing in adapting agriculture
A much wider range of adaptations will be needed if food is to remain as copious, varied and affordable as it is today. These will include efforts to help crops withstand warmer temperatures, for example through clever crop breeding, advances in irrigation and protection against severe weather. Rich and poor countries alike should also make it a priority to reduce the amount of food that is wasted (the UN’s Food and Agriculture Organisation guesses that more than one-third is squandered). The alternative will be a world that is hungrier and more unequal than it is at present—and than it might have been.
That’s from The Economist‘s analysis last week of projected shifts in the distribution of crops around the world as a result of climate change. Needless to say, genetic diversity will be needed to do all those good things. Investors read The Economist, right?
Brainfood: Pollinators double, C4 grasses, Pre-breeding, Lupins resources, New wild coffees, Refugee deforestation, Tuber niches, Sampling strategy, Infection risk, Levant Bronze & Iron Age
- A global-scale expert assessment of drivers and risks associated with pollinator decline. “Key findings: 1) risks to human well-being from pollinator decline are higher in the Global South; 2) there is a clear lack of knowledge about pollinator decline in Africa; 3) loss of managed pollinators (e.g. honey bees) is only a serious risk to people in North America.” That’s according to the main author Dr Lynn Dicks on Twitter.
- Agrochemicals interact synergistically to increase bee mortality. Stress on pollinators is more than the sum of its parts.
- Evolutionary innovations driving abiotic stress tolerance in C4 grasses and cereals. Major C4 crops need more stress.
- Deep scoping: a breeding strategy to preserve, reintroduce and exploit genetic variation. You may not need a separate pre-breeding programme to introduce new diversity into your breeding programme without wrecking it.
- Genomic resources for lupins are coming of age. Maybe we could have a pre-breeding programme now?
- Six new species of coffee (Coffea) from northern Madagascar. Including 4 really narrow endemics. I wonder what they taste like. Start evaluation and pre-breeding?
- Refugee camps and deforestation in Sub-Saharan Africa. Much, much less of an impact that you’d think.
- Suitability of root, tuber, and banana crops in Central Africa can be favoured under future climates. More than you’d have thought.
- Proportional sampling strategy often captures more genetic diversity when population sizes vary. Sample more than you normally would from bigger populations of rare wild species.
- Plant pathogen infection risk tracks global crop yields under climate change. Where yields go up, fungal/oomycete infection risk goes up; where yields go down, so does infection risk. Assemblages will change especially in temperate regions.
- Developments in Subsistence Practices from the Early Bronze Age through the Iron Age in the Southern Levant. From pigs, wild animals and emmer to zebu, camelids, and free-threshing wheats.
