Chinese and desertification management is about as close as you get. And thats hit and miss.
Israel transformed large areas of desert land into orange groves and eucalypt forests. That would be terraforming. Australia supplied the eucalypts.
One of the forests is named after Bob Hawke.
Our own aborigines terraformed Australia with their firestick "cold" burning technique. It allowed eucalypt forests to flourish at the expense of less fire tolerant trees and shrubs, totally changing the nature of the country.
We terraformed Australia when we banned firestick control, and cleared vast areas of native forest for timber and farming.
Early colonial paintings depict the countryside looking like an English rural estate, with open grassy fields and stately trees. That was thought to be a gentrified view of Australia, but it was how it actually looked because of regular burning.
Burning every two years kept small shrubs and new tree growth from flourishing. The established trees could handle the fires, and had room to grow in the sun. The ash from thousands of years of burning made wonderful topsoil for the native grasses. The open, grassy plains were perfect for large animals like kangaroos and wallabies to graze, and gave clear lines of sight for spear throwing. Also made it easier to walk naked through the bush, without being scratched by prickly shrubs.
When we banned regular burning, the shrubs and smaller trees grew and filled up the open parklike spaces into the thick tangle of scrub that we see today, making travel difficult, and a good hiding place for bushrangers. The delicate topsoil was exposed by sheep and cattle eating the grasses to the root, and it soon blew away. Many farmers had a good couple of years, then their crops failed as the soil eroded.
