- Salt-Tolerant Crops: Time to Deliver. Sure, breeding for salt tolerance using crop wild relatives is great, but have you tried just domesticating salt-tolerant wild species?
- Wild and cultivated comestible plant species in the Gulf of Mexico: phylogenetic patterns and convergence of type of use. No word on how many are salt-tolerant.
- Underutilized plants increase biodiversity, improve food and nutrition security, reduce malnutrition, and enhance human health and well-being. Let’s put them back on the plate! No word on how many are salt-tolerant.
- Indigenous crop diversity maintained despite the introduction of major global crops in an African centre of agrobiodiversity. If you want local crop diversity in Highland Ethiopia, look for it on the farms of the poorest. No word on how many are “underutilized”.
- The role of minor cereals in food and nutrition security in Bangladesh: constraints to sustainable production. Low yields, apparently. I think it could do with having aromatic grains. If only there was a way to make that happen…
- De novo creation of popcorn-like fragrant foxtail millet. Yeah, sometimes neither the crop not its wild relatives has the genes for it. Still, if you can edit in aroma, why not salt-tolerance?
- Global Genepool Conservation and Use Strategy for Dioscorea (Yam). I wonder how many of these 27 wild species could usefully be domesticated. Or are salt-tolerant.
- Towards conservation and sustainable use of an indigenous crop: A large partnership network enabled the genetic diversity assessment of 1539 fonio (Digitaria exilis) accessions. This is how you start to undo underutilization. I’m sure someone will edit it next.
- Diversity Assessment of Winged Bean [Psophocarpus tetragonolobus (L.) DC.] Accessions from IITA Genebank. Same as above, but with one hundredth as many accessions. I guess winged bean is even more underutilized than fonio.
- The forgotten giant of the Pacific: a review on giant taro (Alocasia macrorrhizos (L.) G.Don). Sad to say it doesn’t seem to be salt-tolerant. Maybe it’s aromatic, though. Or could be gene-edited to become so. Wouldn’t that be something.
- Retracing the center of origin and evolutionary history of nutmeg Myristica fragrans, an emblematic spice tree species. No need for editing, let’s just conserve the really diverse populations of the North Moluccas.
- Demographic history and distinct selection signatures of two domestication genes in mungbean. Domesticating the mungbean wasn’t all that easy. Hope it’s easier for some random salt-tolerant wild species.
- A plausible screening approach for moisture stress tolerance in finger millet (Eleusine coracana L.) germplasm accessions using membership function value at the seedling stage. Will it work on fonio? Or salt-tolerance?
- Adoption and impact of improved amaranth cultivars in Tanzania using DNA fingerprinting. So can we stop calling it underutilized? And start gene-editing it for aroma?

- Why community seedbanks full of heirloom seeds matter.
- Just how much agrobiodiversity matters, according to FAO.
- Why heirloom seeds of neglected crops matter.
- Why heirloom seeds of sorghum matter in Kenya. No, really.
- Why heirloom grapes matter in Italy.
- Why seeds of wild tomatoes matter.
- Even wild sheep matter.
- Why visualizing coffee diversity matters.

- New evidence of plant food processing in Italy before 40ka. Did modern humans outcompete Neanderthals in Italy by grinding up and eating wild cereals? No, probably not, but still.
- Early Dalmatian farmers specialized in sheep husbandry. Did early Dalmatian farmers outcompete local hunter gatherers by eating sheep? No, probably not, but still.
- Northwest African Neolithic initiated by migrants from Iberia and Levant. Iberians brought farming to the Maghreb, where local hunter-gatherers were both outcompeted and enticed to change their lifestyles, and the whole thing happened again later when pastoralism arrived from the Levant.
- Genetic continuity, isolation, and gene flow in Stone Age Central and Eastern Europe. This outcompeting thing happened to different extents in different parts of Europe.
- Why did foraging, horticulture and pastoralism persist after the Neolithic transition? The oasis theory of agricultural intensification. Lower rainfall and lower biodiversity allowed early intensive agriculture around the world to outcompete other lifestyles.
- New research on crop diversity of the early farmers in southeastern Europe (ca. 6400-5700 BCE). Some crops were outcompeted by others as agriculture spread into Europe.
- The early adoption of East Asian crops in West Asia: rice and broomcorn millet in northern Iran. Starting in East Asia, broomcorn millet reached the Caspian Sea’s southern coast by 2050 BC by infiltrating and rice by 120 BC by leapfrogging. No word on what they outcompeted.
- Redefining the timing and circumstances of the chicken’s introduction to Europe and north-west Africa. It took a long time for chickens to outcompete other sources of food. For a long time they were just exotic pets.
- Pre-Columbian legacy and modern land use in the Bolivian Amazon. Modern farming practices are taking advantage of ancient farming practices in the Llanos de Moxos. Unclear who is outcompeting whom.
Tracing the spread of a map of the spread of the olive
There’s a nice map of the spread of the olive doing the rounds on Twitter.
But where does it come from?
As best as I can make out, the ultimate source seems to be an article on Vivid Maps. All the other maps and illustrations in the article are credited, but this one is not, so I’m thinking the author — Alex — made it him or herself, and a fine job they did too if so.
Where did they get the data? Difficult to say, but there’s a very similar map, though not nearly as nice, in an Encyclopedia of Life Support Systems article entitled Olive Growing in a Time of Change. And that has the following credit (slightly cleaned up, and link added):
Olive diffusion in the Mediterranean Basin. (Adapted from Morettini. 1950. Olivicoltura. REDA, Roma, Italia, by Rallo, L. 2005. In Rallo, L., Barranco, D., Caballero, J. M., Del Río, C., Martín, A., Tous, J. Trujillo, I. (Eds.). (2005). Las variedades de Olivo en España. Junta de Andalucia. Ministerio de Agricultura Pesca y Alimentación. Ediciones Mundi-Prensa, Madrid, España. We acknowledge the permission by authors, scientific editors and publishers).
Which doesn’t really help clarify things an awful lot. Recent work adds an eastern dimension to the spread of the crop.

- Not so cool: some species you can only see in natural history collections. The world is not as diverse as possible.
