Researchers at the Australian Catholic University, Australia; Columbia University, New York; and the University of Massachusetts teamed up to investigate secondary forest growth in previously deforested areas. In their paper, "Collective property rights lead to secondary forest growth in the Brazilian Amazon," published in Proceedings of the National Academy of Sciences, the researchers found that collective property rights with local stakeholders in Indigenous territories lead to higher reforestation rates.
I’d say that depends on the specific land and the specific Indigenous groups. Round here an indigenous corporate entity is one of the worst polluters and GHG emitters and they are currently driving a critically endangered native beetle species extinct by converting the only bit of native forest they live in into profitable dairy farms.
What works in the Amazon won’t necessarily work everywhere!
