The dawn of farming revisited
Yeah, ok, here’s that cool map about the Fertile Crescent that I alluded to in a recent Nibble.
But do read the blog posts by Chad Mulligan the thesis of Graeber and Wengrow’s The Dawn of Everything with regards to the origins of farming Part 1 and Part 2.
In chapters six and seven of The Dawn of Everything, David Graeber and David Wengrow present a very different account of the origins of agriculture than that found most conventional history books. This account, they say, contradicts many of the assumptions made by the authors of Big History, who tend to portray farming as ineluctably leading to inequality, hierarchy, private property, violence, and centralized states.
Instead, they argue that early farming societies were no more hierarchical than their predecessors, and may have even been less violent more egalitarian than their hunter-gatherer neighbors. The imply that cultivation may have even initially began as a strategy expressly designed to avoid succumbing to the values of hierarchy and violence. They are especially critical of Yuval Noah Harari’s Russian reversal-style metaphor of “wheat domesticating us.” This, they say, is yet another “Garden of Eden-type narrative,” except with “wheat taking the place of the snake.”
Nibbles: Brazil agroforestry, US sweet potatoes, Egypt sweet potatoes, Regenerative Carlsberg, Plant Pandemic Studies, The Dawn of Everything, Allianz biodiversity report
- Saleseforce is funding work by CIFOR-ICRAF to help diversify agriculture in the Brazilian state of Pará by growing more nutritious fruit trees in agroforestry systems.
- USDA researchers are breeding sweet potatoes that are better able to deal with weeds. No word on how they do in agroforestry systems.
- I wonder if those weed-resistant sweet potatoes would find a market in Egypt.
- Beer “giant” Carlsberg says it’s going all-in on regenerative barley growing practices. Looking forward to seeing hops agroforestry systems.
- The British Society for Plant Pathology has a series of really engaging Plant Pandemic Studies, including for some crops that do well in agroforestry systems.
- The Dawn of Everything, by David Graeber and David Wengrow, is getting a lot of attention, including for its thesis that agriculture began in the Fertile Crescent as somewhat ad hoc, experimental, diverging, complementary and interacting lowland and highland agroforestry systems, and did not always lead to inequality and hierarchy. With a nice map.
- And finally, here’s a report from Allianz on why the financial sector should care about biodiversity-friendly agricultural systems (pace David Wood), like maybe, but not only, agroforestry.
Brainfood: Food biodiversity, Diversification, New crops, GMO maize, African livestock, Greek innovation clusters, Amazonian native cacao
- Food Biodiversity as an Opportunity to Address the Challenge of Improving Human Diets and Food Security. Biodiversity and food security can be mutually supportive, but you need education, research and inclusion, say educators and researchers.
- Achieving win-win outcomes for biodiversity and yield through diversified farming. Biodiversity and yield both win in only about a quarter of cases. But humanity does not live by yield alone, right?

- Climate Change’s Impact on Agriculture and Food Security: An Opportunity to Showcase African Animal Genetic Resources. Forget GMO maize, Africa needs to develop its own agrobiodiversity…
- Friend or Foe? The Role of Animal-Source Foods in Healthy and Environmentally Sustainable Diets. …and it need not be bad for either health or the environment.
- AgriDiverCluster: An Innovative Cluster for the Utilization of Greek Biodiversity and Plant Genetic Resources. Maybe the Greeks have a way to make it not bad for either health or the environment. By vertical integration, it looks like.
- Socio-ecological benefits of fine-flavor cacao in its center of origin. Amazonian cacao farmers also seem to have a way to vertically integrate.
Brainfood: Why measure genetic diversity?
- Genetic diversity goals and targets have improved, but remain insufficient for clear implementation of the post-2020 global biodiversity framework. The struggle to ensure recognition of the importance of measuring genetic diversity is real, despite the available tools. And despite the range of uses to which the results can be put, as illustrated in the following papers.
- DNA barcoding markers provide insight into species discrimination, genetic diversity and phylogenetic relationships of yam (Dioscorea spp.). Measuring genetic diversity can help you tell species apart.
- Genetic diversity and population structure of barley landraces from Southern Ethiopia’s Gumer district: Utilization for breeding and conservation. Measuring genetic diversity can help you decide what’s new and what to use in breeding.
- Management of genetic erosion: The (successful) case study of the pear (Pyrus communis L.) germplasm of the Lazio region (Italy). Measuring genetic diversity can help you detect genetic erosion and figure out what to do about it.
