The accessions in Spain fall mainly everywhere

My ex-colleagues at the Crop Trust have a very nice animation on the Genesys blog-type thing showing the progress of landrace collecting around the world over the past 125 years.

Do please read the post for the details of how it was done, and some observations on the results.

Here I just wanted to highlight something that has always intrigued me: how did Spain get so heavily collected? It’s really striking how in any global map of collecting localities, Spain looks like a solid carpet, with genebank accessions from practically every nook and cranny. More so than most neighbouring countries, I would say.

Well, it’s a little difficult to be sure because there’s no slider on the animation to take it backwards and forwards at will, but it looks like a burst of collecting first in the 40s, and then some filling in of gaps in the 80s, are responsible for the blanket coverage.

Maybe someone more familiar with the history of germplasm collecting in Spain can explain more.

Brainfood: Avocado history, Brazil commuity seedbanks, Citizen science, Agroecology double, Indigenous knowledge, Turkish seeds, Swiss biodiversity

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns. DNA from landraces, and interviews with farmers, show that people transported and cultivated avocados across the Americas long before European contact, with landraces from lowland Nicaragua and Honduras in particular showing evidence of ancient migration from South America.
The Circle of Seeds: An Ethnography of Seed Guardianship and the Making of Agroecological Futures in Paraná, Brazil. Community seed banks depend on relationships of care, reciprocity and collective labour, especially among women farmers, and not just on knowing how to store seeds properly. Though that helps, clearly.
iNaturalist as a Tool to Improve Agroecological Biodiversity Knowledge: An Ecuadorian Case Study. A citizen science platform can strengthen agroecological biodiversity knowledge, but more efforts are needed to engage farmers.
Are agroecological practices pro-poor? Evidence from smallholder farms in Zimbabwe. Farmers using agroecological practices were generally wealthier and their farms were more diverse in crop and livestock species, but the association between the use of improved practices and diet outcomes was inconsistent.
Regenerative agriculture for dietary diversity and food security in Zambia. Agroecological practices were positively correlated with improved dietary quality and food security, including (though not exclusively) through farm production diversity. No word on the wealth of the farmers involved.
Indigenous Peoples’ knowledge systems and practices for climate survival. Indigenous knowledge systems, including of farmers, offer tested approaches to climate adaptation and resilience that warrant a central place in responses to environmental change.
Guardians of Agricultural Biodiversity: Farmer Perceptions and Sustainability of Local Seed Varieties in Turkish Highlands. Farmers continue to maintain local seed varieties, driven as much by social, cultural and market considerations as by agronomic performance. But they need support.
Religion, spirituality and faith of Swiss farmers in relation to biodiversity-linked farming behaviour. Farmers’ religious and spiritual values can shape biodiversity-friendly management decisions, showing personal belief systems are important in conservation. Even in Switzerland.

Smelling the heirloom coffee

Yet more on agrobiodiversity marketing in Kenya. This time it’s coffee.

Spring Valley Coffee gives out nifty little cards on all its products, providing information on the varietal composition of different blends, and where the beans that go into each are grown.

This decaf from Guji in Ethiopia caught my eye in particular…

…because the variety involved is a heirloom. But also because if you’re going to those lengths, why not quote its local name?

Anyway, still a pretty nice idea.

High on taro

The South Pacific nation of Vanuatu is having its National Agriculture Expo 2026 from August 3–7, 2026, on the northern island of Maewo. I’ve scoured the internet for information about this, but all I could find was social media posts, which I won’t link to, but you can find for yourself quite easily. I will, though, share, with thanks, this photo from one of those posts from Facebook. It’s of the 20-metre tower built by the taro farmers of Maewo, showcasing their product. Because it’s amazing.

The flour of Kenyan agrobiodiversity marketing

Here’s the latest in my continuing series of posts on interesting approaches to marketing agricultural biodiversity here in Kenya.

I was pleasantly surprised by this product, which seems to add finger millet and cassava to your basic maize flour for making ugali. A nice way to add taste and nutrients. And support some minor crops.

And this line of porridges is quite impressive, in the range — and presentation — of both their composition and consumer targeting.
