- ntbox: an R package with graphical user interface for modeling and evaluating multidimensional ecological niches. Yes, another one, deal with it.
- Global targets that reveal the social–ecological interdependencies of sustainable development. The post-2020 framework should not have separate targets for social and ecological outcomes.
- Integrating agroecological production in a robust post-2020 Global Biodiversity Framework. Case in point?
- The Historical Impact of Anthropogenic Climate Change on Global Agricultural Productivity. We’ve lost a decade of productivity growth since 1961.

- Editorial: Leeway to Operate With Plant Genetic Resources. Research Topic on ABS, biosafety and IPR regulations and how they affect use of PGR.
- SNP Markers and Evaluation of Duplicate Holdings of Brassica oleracea in Two European Genebanks. Out of 10 pairs of accessions with similar names in the Russian and Nordic genebanks, 5 showed genetic differences, and 3 of these also morphological differences.
- History of crop introductions, breeding and selection in Australia: The 140 years from 1788. But at what cost?
- The welfare effects of crop biodiversity as an adaptation to climate shocks in Kenya. Crop diversity mitigates income variability risk caused by climate.
- Genetics of yield, abiotic stress tolerance and biofortification in wheat (Triticum aestivum L.). Well that seems sorted then.
- Is plant variety registration keeping pace with speed breeding techniques? No?
- Global Cropland Connectivity: A Risk Factor for Invasion and Saturation by Emerging Pathogens and Pests. Nice maps of ease of movement among different cultivation areas of vegetatively propagated crops. Could be used to model movement of genetic resources as well as of pests/diseases?
- Global patterns of population genetic differentiation in seed plants. More population differentiation for tropical, mixed‐mating, non‐woody species pollinated by small insects, and lower for temperate, outcrossing trees pollinated by wind. Could perhaps be mashed up with this fragmentation database.

Jeremy’s latest newsletter expounds eruditely on, among other things, some recent articles on durian, Australian grasses and a heirloom pepper that we Nibbled here way too briefly. Always worth a read. Jeremy also gave me the go-ahead to reproduce here his piece on coping with Covid-19 in Kenya, which reminded me, as if I needed reminding, of what my assorted nephews and nieces are going through. Not to mention the mother-in-law. Here it is.
Deep insights from Oyunga Pala, a Kenyan currently in the Netherlands, prompted by how Covid is encouraging many Kenyans to return from the cities to small rural land holdings where they hope to create a basis for food security. Pala contrasts what he knows of small-scale agriculture in Kenya with what he is learning and what he sees all around him in the Netherlands.
Small-scale farming in Kenya accounts for 75 per cent of the total agricultural output and meets 70 per cent of the national food demand, so I know I am part of an important constituency. The challenge of my generation, those with access to land under 3 ha in size, is to craft a new farming philosophy that is built on progressive ideas through investigation, dialogue and exposure to alternative sources of knowledge grounded in the African experience. We need more philosophers and fewer technical experts to redefine what we call sustainable farming. Africa’s own knowledge systems and philosophy in agriculture are held in the memory of a generation that is dying out and dismissed as backward. Yet my grandmother’s practices resonate with those of emerging natural farming systems around the world that espouse new ideas grounded in the environmental, social and historical realities of the non-western world.
Seems to me to echo what other people are saying about AGRA, the Alliance for a Green Revolution in Africa.
Well worth your time, as are the articles Pala links to. I know nothing about Elephant, the online publication, but it looks like a good source of interesting news.

- A research vision for food systems in the 2020s: Defying the status quo. Research is necessary but not sufficient.
- Dismantling a dogma: the inflated significance of neutral genetic diversity in conservation genetics. Not all genetic diversity is created equal.
- A re‐evaluation of the domestication bottleneck from archaeogenomic evidence. Not so much a single bottleneck “event” on domestication, as serial bottlenecks post-domestication. Another dogma dismantled?
- Morphological and genetic diversity of Slovene lettuce landrace ‘Ljubljanska ledenka’ (Lactuca sativa L.). Not all iceberg is created equal.
- Genetic Status of the Swedish Central collection of heirloom apple cultivars. Neutral diversity is not completely useless, though?
- Understanding genetic variability in the mungbean (Vigna radiata L.) genepool. It may not be neutral variation, but it’s not associated with geography. If you see what I mean.
- A Land Evaluation Framework for Agricultural Diversification. Soil and climate data –> fancy maths –> pretty good prediction of where you find a crop.
- A unifying concept of animal breeding programs. You can describe any breeding programme by using graph theory. But would it help?
- Molecular and isotopic evidence for milk, meat, and plants in prehistoric eastern African herder food systems. Chemical and isotope analysis of lipids on ceramic shards shows early herding societies had a pretty diverse diet.
- Pre-Clovis occupation of the Americas identified by human fecal biomarkers in coprolites from Paisley Caves, Oregon. Lipids again, this time at the other end of the process, and of the world.
- Identification of novel seed longevity genes related to oxidative stress and seed coat by genome‐wide association studies and reverse genetics. Seeds need to take their antioxidants.
- Evaluation of genetic integrity of pearl millet seeds during aging by genomic-SSR markers. Loss of viability leads to loss of diversity.
- Geographical distribution of quinoa crop wild relatives in the Peruvian Andes: a participatory mapping initiative. Cultivated land is as important as more “natural” ecosystems for quinoa wild relatives.
- Global wind patterns and the vulnerability of wind-dispersed species to climate change. In the tropics, and in the lee of mountains, wind-dispersed species will find it more difficult to reach places with suitable future climates.

- Perennial vegetables: A neglected resource for biodiversity, carbon sequestration, and nutrition. Over 600 perennial veggies on 6% of global vegetable cropland.
- Genomic Evidences Support an Independent History of Grapevine Domestication in the Levant. Separate from what happened in the Caucasus, that is.
- Distribution, prevalence and severity of damages caused by nematodes on yam (Dioscorea rotundata) in Nigeria. A quarter of tubers and half of heaps showed nematode symptoms.
- Maize long-term genetic progress explains current dominance over sorghum in Argentina. Follow the money.
- Phenotypic and physiological responses to salt exposure in Sorghum reveal diversity among domesticated landraces. Salinity tolerance was acquired early but then lost in some geographic regions where it wasn’t needed. See what happens when you invest in a crop?
- Massive haplotypes underlie ecotypic differentiation in sunflowers. It’s the recombination-suppressing inversions, stupid.
- GlobalFungi, a global database of fungal occurrences from high-throughput-sequencing metabarcoding studies. Cool. Do landraces of a crop next.
- The earliest domestic cat on the Silk Road. Coincided with rapid urbanization in the 9th century.
- Native American gene flow into Polynesia predating Easter Island settlement. Yeah, but did Americans go west of their own accord or in Polynesian boats? And did they have sweetpotatoes with them? And cats?
- Genetic markers associated with seed longevity and vitamin E in diverse Aus rice varieties. 5 markers on 4 chromosomes.
- Biogeoinformatics for the management of Farm Animal Genetic Resources (FAnGR). Software for monitoring erosion and detecting locally adapted genotypes. Plus preserve traditional practices.
