Deforestation of forests in the Amazon has reached a new and alarming level in the last three years. The loss of forest between 2019 and 2021 exceeded 10,000 km² per year, a number 56.6% higher than the annual average of the previous period – 2016 to 2018.

Although a considerable portion of deforestation is located on public lands, especially federal lands, environmental governance in the Amazon lacks action at all federal and private levels. The responsibilities of the federal, state and municipal governments, as well as the private sector in decision making for land use both in public and private lands, are fundamental for better planning and prioritization of command and control actions, starting with the most critical areas that demand urgent action.

To this end, it is necessary to understand the geographical distribution of deforestation in the main land tenure categories in order to be able to contribute, effectively and efficiently, to overcoming the current context of loss of this natural heritage.

In this technical note, we detail the places where deforestation has occurred in the last six years, focusing on a “before and after” change by the federal government, according to the different land categories in the Amazon biome.

Fire, fragmentation, and windstorms: A recipe for tropical forest degradation

Widespread degradation of tropical forests is caused by a variety of disturbances that interact in ways that are not well understood. To explore potential synergies between edge effects, fire and windstorm damage as causes of Amazonian forest degradation, we quantified vegetation responses to a 30‐min, high‐intensity windstorm that in 2012, swept through a large‐scale fire experiment that borders an agricultural field. Our pre‐ and postwindstorm measurements include tree mortality rates and modes of death, above‐ground biomass, and airborne LiDAR‐based estimates of tree heights and canopy disturbance (i.e., number and size of gaps). The experimental area in the southeastern Amazonia includes three 50‐ha plots established in 2004 that were unburned (Control), burned annually (B1yr), or burned at 3‐year intervals (B3yr).
