I was addressing two separate points you made. I thought the "---" would make that clear.

> This is alarmingly false.

I'm sorry but I can't take your comment more seriously than a paper published in a respected journal that has been cited 1,099 times. It provides 4 sources to back up the claim I posted.

In scholarship on land use history this is pretty well accepted.

As for the specific chinampas yields, such high yields shouldn't be surprising when you have 4-7 harvest per year and require no periods of being fallow.

The UN's FAO provides more specific breakdowns on yields on page 22 of their report

You're have to download it but the designation also has more specific figures

Your source says:

> It is clear that the yield per crop varies depending on the species and variety sown. However, in the case of the chinampas, yields are between 10 to 15 tonnes/hectare. An average of 12.5 tons/ha

That's not 80 tons per hectare as you stated.

You took the quote out of context, it's about rice agriculture in South East Asia, not Xochimilco. I check the citations and you obviously didn’t.

You are blatantly making things up here and trying to back your bullshit claims with papers that you are misrepresenting.
