It seems to me that traditional ecological knowledge as a category is tied to long periods of isolation from networks of trade, but I might be mistaken. Why do ecological practices (such as nutrient recycling through manuring and plowing in crop residues) in medieval European communities not count as traditional ecological knowledge?
While I am no expert, this topic is similar to others in that it is a product of a colonial framing.
“Traditional” in colonial and post-colonial areas usually applies to systems that pre-date colonisation, and is used to distinguish between the two. Therefore, European agricultural systems aren’t seen as “traditional”, they’re seen as “normal”, and the systems that Indigenous peoples used were in opposition.
