Untitled public forestlands threat Amazon conservation

A large proportion of recent Brazilian Amazon deforestation is occurring on untitled public forestlands through land grabbing. This emerging risk demands long-term conservation strategies. Here we propose prioritizing land tenure security, technological improvement, and law enforcement.

Land-tenure insecurity has been a long-lasting issue in the Brazilian Amazon. It involves the uncertainty of recognition of a person’s right to land (or a public body’s management right) and the consequent risk of having it threatened and even lost by competing claims. Land-tenure insecurity, thus, is at the root of the difficulties in adopting sustainable land use models.

Fire-induced forest transition to derived savannas: Cascading effects on ant communities

Changes in land-use and climate increase the flammability of forests across southeast Amazonia, potentially driving abrupt fire-mediated transitions to derived savannas – grass-dominated degraded forests with scattered trees. However, the extent to which the forest fauna undergoes a parallel process remains poorly understood.
