Sounds solarpunk, I’m in.
It feels like this should have been obvious a century or few ago. Marsh gas and sewer gas have been things for millennia.

> Biome: flooded grasslands and savannas

Modern agricultural irrigation is draining aquifers.
Aeroponics is a form of hydroponics that uses less water.

How extensive were hydrological agricultural practices in the ancient Americas?

There are occasional stories of this tone for different kinds of terrain: boreal forest, savannah, woodlands, wetlands and so on. Do any firms do work to match existing planning bodies for optimal wilderness land use with all of the current cutting-edge findings or do they stay locked inside the science reporting bubble?
They stay locked in the science reporting bubble. The only real reason this was funded (IMO) is because it also has multi-faceted potential to increase arable land, treat air and water pollution, create habitat for aquatic creatures, and improve farming output. Implementing it is a whole different ball game financially than a proof of concept though.
Water Hyacinths have been used for sewage treatment for quite some time [1].

Like some way to fill up an empty parking lot at an empty office park or strip mall with portable self-watering containers that contain something like grass or bamboo or de-THC hemp.
No need to re-zone anything, just roll up with it while the land is not being used, soak up some carbon, and then move on if the land gets used again.
