From a purely numeric standpoint, you are right about the 'highest genetic diversity is in wild species'. And from a nature conservation perspective, I am with you. We had some really nice discussions about this in our biodiversity lectures...
And the quality of many tradicional varieties is like 'local' cuisine is frequently 'foods that not e en the people from the next village wanted to eat' 🤣 (to paraphrase Terry Pratchett).

However, I would like to add the following:
There is some inherent value in traditional agrobiodiversity. Modern plant breeding has also some drawbacks. Modern plant breeding is powerful process, capable of integrating very distant genetic material into crops, and thus also greatly increasing genetic diversity. And it's quick. However, the process is out of control if the farming community. And the focus lies usually more on a few specific traits, not a gradual complex adaptation like in decades long heirloom breeding. Thus, the traditional cultivars with their complexity and messiness are not easily replaced.

On the other hand, I have frequently heated discussions with the 'heirlooms are the only solution'-people. I disagree a bit, because since industrial capitalism is wrecking the climate and local climate is not what it waswhen heirloom varieties evolved (you know this of course, I provide the reference for others: https://e360.yale.edu/features/redrawing-the-map-how-the-worlds-climate-zones-are-shifting). A worrying question I have not yet a clear answer is: is the breeding&adaptation rate of heirloom varieties quick enough to keep pace with the climatic shifts that will happen in this century?
A few months ago, on a very cool ethnobotany conference some folks presented their seed bank project safeguarding and reintroducing traditional varieties in northern Catalonia (Spain). I challenged them with the shifting climate zones argument and asked about resilience. But I have to admit that the answer was very convincing to me:
Traditional cultivars are connected to a different way of doing agriculture. Also in a farmer-cultural way. For example, this seed bank project created community and motivated farmer-to-farmer exchanges of knowledge and experience. They improved productivity while decreasing environmental impact. And had exchanges with farmers from Morocco (500km south) who teaches them management techniques for arid climates, much needed in the increasingly scorching summers. The answer ended with "our heirloom seedbank is much more than the seeds. It is a community project".

Therefore, one would hypothesize that farming systems with traditional cultivars *tend* to favour more #agroecology practices, small-scale mosaic landscapes, increasing #biodiversity (especially, when doing the grossly simplified and unfair comparison between #PeasantFarming to industrialised large scale farming with modern varieties that were optimized for high-input farming).
Thus, there are system components on different levels we should not forget in this discussion.  

Thank you for your always very informative threads! 🌱

Redrawing the Map: How the World’s Climate Zones Are Shifting

Rising global temperatures are altering climatic zones around the planet, with consequences for food and water security, local economies, and public health. Here’s a stark look at some of the distinct features that are already on the move.

What secrets did a 9th-century peasant’s daily life hold?

Bodo was a early 9th-century Frankish farmer. He and his family hailed from a manor owned by the monastery of St.-Germain-des-Prés near Paris and worked as its tenants. He ploughed the farmlands while...

Agroecology is a social movement originated by peasant farmers in the global south but nowadays spread over the whole world.

https://agroecologyfund.org/what-is-agroecology/

One of the main organizations is @ViaCampesina .

And agroecology is a field of research where scientists combine the most advanced interdisciplinary knowledge of agricultural ecosystems (I am a soil microbiologist and work with botanists, entomologists (insects), agronomists, food chemists, but also sociologists and economists) with the applied understanding of farmers and indigenous people to develop and promote sustainable farming techniques and a transformation of the food system.

This is because from a scientific point of view, the industrial food system has way too many disadvantages, destroying the planet, society and our health.

What is Agroecology? - Agroecology Fund

What is Agroecology? Agroecology is an integrated approach that simultaneously applies ecological and social concepts and principles to the design and management of food and agricultural systems. Within a justice and rights framework, it seeks to minimize external inputs and optimize sustainable interactions between plants, animals, humans and the broader environment. Agroecology is not a […]

Absolutely worth reading! 🖤

“It really isn’t about the crop, like rubber in this case, but about the system in which different commodities are produced, traded and consumed and the length of the value chain associated with them.”

Additionally, the study finds that in some countries, palm oil has expanded into areas where rubber was traditionally grown, with new rubber plantations then being established elsewhere, driving further deforestation.

“Because rubber is non-perishable and can travel long distances, the typical top-down approach of tracing things for rubber is difficult. You don’t know how the rubber got to the processing facility.

“I think that challenge is actually better addressed from the bottom up, as pioneered by the Forest Stewardship Council who work with smallholder cooperatives. These cooperatives can jointly negotiate a price and can collectively say that the rubber comes from this region, versus millions of smallholders competing for an already very low rubber price.”

She [Dr. Antje Ahrends, one of the authors] adds that it is “absolutely” critical that the EU deforestation regulators distinguish between farmers renewing existing rubber plantations and new deforestation of natural forest for new plantations.

The intent of the study is “not to demonise, but encourage smallholder production”, while also ensuring rubber does not lead to continued deforestation, Ahrends says. She adds:

“Rubber is a really good income source for smallholders, if it can be managed properly. It can store between 50 to 250 tonnes of carbon per hectare. If you have the choice between a field of pineapple and field of rubber, rubber is also environmentally the better choice: less pesticide, more carbon storage, better longevity, you can intercrop it, form agroforests you could never do with pineapple.

“Natural rubber is also much better than synthetic rubber, which is produced from, essentially, fossil fuels.”

Ahrends stresses the importance of educating farmers to minimise deforestation and form cooperatives to use fewer pesticides and not “overtap” trees, so that plantations do not need to be replaced so quickly. Rubber trees typically have an economic lifetime of 20 to 30 years.

Meijaard says it is important to look at how governments decide to allocate land for agricultural production and how to design land use optimally to deliver the highest environmental opportunities and retain natural areas. He tells Carbon Brief:

“I hope that the global discussion around this paper is not going to be ‘my god, we have another devastating crop that’s wiping out Indonesian rainforest’. That’s not particularly useful. The discussion I hope we have and should all be involved in is: how do you produce the commodities that the world needs and requires most optimally, from a nutritional, social and an environmental perspective?”

From the perspective of animal welfare, lab meat makes sense.

Environmentally, the answer is not so clear in the case of free ranging beef when including soil carbon storage in grassland-rumiant ecosystems. Admittedly, the grasslands would need to be managed very biodiversity-friendly and there are simply not enough grasslands to feed 9 billion people with a western meat overconsupmtion habits.
And for pig & poultry, except in a backyard or really smallscale farms there is anyway no sustainable production.

So, for an electricity-based meat production (btw, where do they source their raw materials? Recycled organic wastes? Legumes?), we need to consider the direct and indirect emissions of the electricity system. In many countries, the share of renewables is on the rise, but currently, solar and wind are mainly adding production capacity to cover the increases in consumption, with only slight decreases in total emissions of the energy sector because coal, gas and oil are still burned. All the promoters of tech-solutions assume that their product will use only zero emission electricity, without having marginal effects on the whole system.

Then there is the health perspective: Although I cheer every meat alternative that helps to bring down factory farming, I am reluctant of ultraprocessed foods produced by intransparent companies (But that is not my field of expertise, more a gut-feeling).

And finally, what I think is the most important point and also interesting for anthropologists: the dependence on highly centralized and technizised systems for food production is not a good idea. Not for resilience as they have vulnerable supply chains (a lab needs many components from different parts pf the world, starting with latex gloves). And not from a cultural perspective, as food production is an inherent part of human subsistence. It is unwise, to be totally disconnected from the people that produce our food and their way of live.
