I mean throughout the Americas you see really complex polycultural farming traditions including the famous chinampas. In Mesoamerica you also have the milpa cycle which is a system where you clear most herbs and lightly burn it to grow your crops in polycultures. After a few years, you grow more trees and these fields turn more into managed orchards that include both fruit trees and trees grown for lumbar. Eventually you let it progress into a closed canopy system.
That's just one example, but there are plenty other I could think of that are in very stark contrast to anything you see from European civilizations.
With these things it's always an issue of scale. What people don't realize about e.g. homesteading is that it's actually really easy to be entirely self sufficient on very small plots of land. But the tricky thing in the past was transport - when you start shoving many thousands of people into very small areas, you need to start producing more and more food in (relatively) smaller and smaller areas.
Modern times has alleviated this constraint because of mass transport. Now moving tons of cargo hundreds of miles, or even half way around the world, is trivial and relatively rapid, but in ancient times you're looking at moving small amounts of cargo extremely slowly, all under the time pressure of spoilage/infestation. The way places like Rome solved this, or at least alleviated it, was by using river transport but then you're imposing some significant technological, infrastructural, and geographical requirements on settlements.
And then you also need to deal with bad harvests, war, and other such issues. In decentralized systems where most are doing their own thing, this isn't such a big deal. But in a heavily centralized system where potentially millions of people are dependent upon deliveries, a single disrupted harvest could spell the end of a civilization if not properly prepared for. And ancient beliefs that things like human sacrifice could ensure rain were likely in opposition to the rational necessity for preparation of inevitable failures.

As a related topic, this is also why war is considered a game of logistics. Think about feeding and providing the other necessities for 10,000 people for just one day. Now imagine doing this for weeks, months, and years - when all those necessities need to come through areas that are potentially being attacked. The fact that war with armies of hundreds of thousands is even possible is quite amazing when you think about the logistics involved just to survive, let alone actually engage in combat.

This is one of the reasons they flourished near river networks that provided easier transport as well as food. They also build canals, but I’m not sure they were for navigation as much as irrigation.
I recall reading of somewhat similar rotational cropping traditions indigenous to Africa though those centered mostly around root crops like yams. Modern smallholder farms still often practice rotational cropping because of this history (something which the west has only relatively recently come around on).
East Africa practiced stuff like homegardens which can be complex, multi-layered agroforestry systems that usually surround homesteads. I've heard the Hausa traditionally did something similar.
I haven't read nearly as much on African agroforestry systems though so I can't recommend much readings. Most of what I recall comes from a college course I took a very long time ago on economic anthropology

Homegardens seem much smaller in scale than large-scale chinampas as practiced by the Aztecs, right?
