- Integration of expert knowledge in the definition of Swiss pear core collection. Let stakeholders choose a few, it won’t make too much of a difference to the overall diversity, and they’ll be pleased.
- Can agricultural intensification help to conserve biodiversity? A scenario study for the African continent. Land sparing is better for biodiversity and food production.
- Influence of experimental design on decentralized, on-farm evaluation of populations: a simulation study. Replicate populations of interest rather than controls, and environments.
- Botanicals used for cosmetic purposes by Xhosa women in the Eastern Cape, South Africa. 16 plants, 14 families, bark the most common component, skin complexion the most common use.
- Droughts, Biodiversity, and Rural Incomes in the Tropics. More access to natural biodiversity means smaller effect of drought during the growing season on income from crops.
- A global surveillance system for crop diseases. Could be extended to other threats to crop diversity?
- A data-driven approach improves food insecurity crisis prediction. Market data, rainfall, geography and demography predict food insecurity at village level in near real time.
- Rapid detection of stressed agricultural environments in Africa under climatic change 2000–2050 using agricultural resource indices and a hotspot mapping approach. Increasing trouble for Tanzania, Zimbabwe, and to a lesser extent Ethiopia. But will biodiversity, disease monitoring and food insecurity prediction help?
- Kavalactones and Flavokavins Profiles Contribute to Quality Assessment of Kava (Piper methysticum G. Forst.), the Traditional Beverage of the Pacific. High-throughput HPTLC will do the job.
- Transcriptome and organellar sequencing highlights the complex origin and diversification of allotetraploid Brassica napus. 6 genetic groups: Winter rapeseed in Europe and America, Rutabaga, Spring rapeseed, Siberian kale, Winter rapeseed in East Asia, and Winter rapeseed in Europe and South Asia. No evidence of multi-origin.
- Parallels between natural selection in the cold‐adapted crop‐wild relative Tripsacum dactyloides and artificial selection in temperate adapted maize. Artificial selection for temperate adaptation in maize involved the same genes as natural selection for temperate adaptation in Tripsacum.
Reforestation: Where, why, and how much?
There’s been a spate of papers on reforestation just lately and I was despairing of being able to keep track of them, let alone read them. But along comes Jonah Busch, Chief Economist at Earth Innovation, to make sense of all the maps in a couple of tweets:
Here are maps of reforestation's potential, feasibility and benefits, and costs pic.twitter.com/fK3jyFPjSr
— Jonah Busch (@jonahbusch) July 5, 2019
Here are the papers:
- Potential: The global tree restoration potential.
- Opportunities: Global restoration opportunities in tropical rainforest landscapes.
- Costs: Potential for low-cost carbon dioxide removal through tropical reforestation.
Thanks, Jonah!
LATER: There’s a nice round-up of two of the studies in Mother Nature Network. Bottom line is in the title: Massive reforestation might be the moonshot we need to slow down climate change. That doesn’t mean forests are a silver bullet, though.
LATER STILL: And, of course, who is also important.
AND FINALLY: Some objections have arisen…

- Plant health emergencies demand open science: Tackling a cereal killer on the run. …but openness will get us through it.
- Rapid evolution in plant–microbe interactions – a molecular genomics perspective. Until the next one.
- Understanding food systems drivers: A critical review of the literature. Spoiler alert: urbanization, raise in consumer income, population growth, attention paid to diet & health issues, technological innovations, intensification and homogenization of the agricultural sector, increase in frequency and intensity of extreme events, general degradation in soils and agro-ecological conditions, improved access to infrastructure and information, trade policies and other processes influencing trade expansion, internationalization of private investments, concerns for food safety. I guess diversity is in there somewhere.

- The Hoard of the Rings. “Odd” annular bread-like objects as a case study for cereal-product diversity at the Late Bronze Age hillfort site of Stillfried (Lower Austria). Unbaked, tarallini-like dried wheat/barley dough rings may have been used ritualistically. No, not like that.

- QTL × environment interactions underlie adaptive divergence in switchgrass across a large latitudinal gradient. You can combine alleles which are locally advantageous in different places to get a

- New evidence on concentration in seed markets. Not as bad as some people think.
- Climate change has likely already affected global food production. From 2003 to 2008, there’s been a ~1% average reduction in consumable food calories in barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat.

- Palaeogenomic insights into the origins of French grapevine diversity. Ancient DNA from 28 pips dating back to the Iron Age provides pretty good matches to grapes grown today.
- Global dataset shows geography and life form predict modern plant extinction and rediscovery. Almost 600 plants went extinct in modern times, at least, and I count about 20 crop wild relatives among them.
