Spillover effect offsets the conservation effort in the Amazon

Conservation policies have achieved impressive reduction in the rate of deforestation in the Amazon biome in Brazil. However, the use of "telecoupling" framework has helped identify spillover effects of these conservation actions: major increases in deforestation and native vegetation loss in the neighboring Cerrado biome, the tropical savanna biome with high biodiversity value as well.

Evaluation of successful conservation efforts usually focused on the impacts within the targeted places only, while the effects that spill over to other areas (e.g., displacement of environmental pressure from one area to another) were rarely considered. To achieve a holistic evaluation of the spillover effects, we adopted the telecoupling framework in our analysis of the Amazon and Cerrado biomes.

Our results indicate that the supply-chain agreements have significantly reduced deforestation by half compared to projections within the sending system (i.e., Pará State in the Amazon, which exports soybeans and other agricultural products), but at the cost of increasing deforestation in the spillover system (i.e., a 6.6 time increase in Tocantins State of the Cerrado, where deforestation was affected by interactions between the Amazon and other places). We used an interactive story map to tell you more about this paper and our findings.
