Uncontrolled Illegal Mining and Garimpo in the Brazilian Amazon.

Mining has played an important role in the economies of South American countries. Although industrial mining prevails in most countries, the expansion of garimpo activity has increased substantially. Recently, Brazil exhibited two moments of garimpo dominance over industrial mining: 1989-1997 and 2019-2022.

Mangrove changes over the past decade in South and Southeast Brazil using spaceborne optical and SAR imagery.

Mangroves occur in the tropics and subtropics. This region is constantly covered by clouds and therefore highly challenging to map and monitor. Technological advances in remote sensing have increased the flexibility of performing such analyses.
