The problem is apparently the tall bamboo that is taking over and not letting native tree to grow. This bamboo does not have home grown competition although it is a native bamboo. The who thing probably needs some sort of automated tilling and panting or imported workers to remove the the giant bamboo and farm it somehow perhaps.

why do you say that?

I didn't see it in the article nor the 2025 study https://www.nature.com/articles/s41893-025-01578-w

Additionally, the article points to Spain and Lake Constance in the Alps exhibiting similar effects.

		Wow the Spain is even more strange. It was over farmed and plowed so much that soil is degraded to become like concrete and barren because the water doesn't soak in. https://www.youtube.com/watch?v=ZUzZk_uqSWc&t=107s For that type of devastation, I recall reading years ago that growing rye and then rolling it instead of plowing it and replanting rye again for multiple seasons can create moisture retaining top soil. They would also need to add ditches to have pools of water for wild life to make a come back. It is a completely different phenomenon. In 500 years all these lands are going to have an ecosystem again even if they don't do anything but they have to live with it for 100s of years if they don't do anything.
