Many thanks to Victor Kommerell for pointing me to a new paper representing a sort of culmination of work that we first blogged about back in 2007. The older paper posed a question in its title: Can biological nitrification inhibition (BNI) genes from perennial Leymus racemosus (Triticeae) combat nitrification in wheat farming? The answer now seems to be a resounding maybe.
- Food systems: seven priorities to end hunger and protect the planet. Oh good, includes “Biodiversity and genetic bases need to be protected. Seed varieties must be preserved, and their phenotypes and genotypes explored in the contexts of climate change and nutrition. Traditional food and forest systems, including those of Indigenous peoples, need to be better understood and supported in national agricultural research systems.” Phew.
- Future Changes in Wet and Dry Season Characteristics in CMIP5 and CMIP6 Simulations. The above is just as well because longer hotter and drier spells are coming to the tropics, and crops will suffer.
- Global assessment of the impacts of COVID-19 on food security. Plus there’s this too. Resilience has a cost.
- The future of farming: Who will produce our food? Smallholders…
- When agriculture drives development: Lessons from the Green Revolution. …and that may be bad.
- Ok, the above two entries need unpacking. The second paper shows that the “agricultural engine of growth” was totally a thing during the Green Revolution, but the first that it now appears to be broken.
- Extinction risk of Mesoamerican crop wild relatives. Oh no, on top of everything else, we might lose avocados and vanilla.
- Determinants of Smallholder Maintenance of Crop Diversity in Morocco’s High Atlas Mountains. Markets, land and water. So what would any new Green Revolution do to diversity? Have we learned anything?
- Landscape complexity and US crop production. …are positively correlated. For Morocco too, I wonder?
- Utilize existing genetic diversity before genetic modification in indigenous crops. At least in Ethiopia.
- Compulsion and reactance: Why do some green consumers fail to follow through with planned environmental behaviors? Because some believe in technology, and other is abstinence. Which means they need different messages to encourage them to put their money where their mouths are. Would it work in Ethiopia?
The publication of “Legacy genetics of Arachis cardenasii in the peanut crop shows the profound benefits of international seed exchange” in PNAS rang a faint bell:
Here, we uncover the contribution of one wild species accession, Arachis cardenasii GKP 10017, to the peanut crop (Arachis hypogaea) that was initiated by complex hybridizations in the 1960s and propagated by international seed exchange.
And yes, it turns out we had blogged about this wild peanut species more than a decade ago, in Another feel-good crop wild relative story.
Some things have changed since 2008, I’m happy to say. I seem to have had some difficulty pulling together data1 at the time, whereas Genesys had no trouble at all showing me 45 accessions. And GKP 10017 even has a DOI now.
