“…However, one study suggests that where pasture and cattle ranching are already present, an increase in the relative crop-tobeef price index has been associated with a reduction in deforestation by raising agricultural input prices, driving low productivity cattle ranchers out of agriculture [97]. Conversely, high wood prices were correlated with decreased deforestation in the Brazilian Amazon, as forests had investment value and were not fully cleared for agriculture (rather selectively logged) [95,98,99]. In the Ecuadorian Amazon however, extracted timber volume correlated with deforestation, as income from selling timber as a byproduct was often used for further agricultural expansion [82].…”

“…Several variables that pertain in one way or another to wealth and capital availability have contradictory results (both positive and negative effects) at the Brazilian Amazon-scale (measured by GDP per capita) [79,95,[100][101][102][103] and at the micro-scale (measured by many different proxies for household income, wealth, and off-farm work) in Brazil, Ecuador, and Peru [98,99,[104][105][106][107][108][109][110].…”

“…Demographic: Population size and growth were found to be important underlying drivers of deforestation at the regional scale in Colombia [93] and Brazil [101]. Yet, at more local scales in Brazil and Ecuador the impact of household size and composition had varied impacts on deforestation with no clear directionality [66,82,87,99,106,113,114].…”

The Amazon biome, spanning nine countries, has one of the highest rates of deforestation worldwide. This deforestation contributes to biodiversity loss, climate change, the spread of infectious diseases, and damage to rural and indigenous livelihoods. Hundreds of articles have been published on the topic of deforestation across Amazonia, yet there has been no recent synthesis of deforestation drivers and deforestation-control policy effectiveness in the region. Here we undertook the first systematic review of papers published between 2000 to 2021 that have causally linked proximate and underlying drivers and policies to deforestation outcomes in Amazonia. In the 155 articles that met our inclusion criteria, we find that causal research is concentrated in Brazil, and to a lesser degree Peru, Ecuador, and Bolivia. There has been little study of the Guianas, Venezuela or Colombia. Large- and small-scale agriculture linked to improved market access and high agricultural prices are frequently researched proximate drivers of deforestation across the heavily researched regions. In the Guianas research focuses on mining with little focus on underlying causes. Research on infrastructure expansion, mining and oil extraction and on technological, sociocultural, and institutional factors remains sparse. Many public and private policies have been found to be effective in controlling deforestation across the biome, with protected areas standing out as particularly successful in slowing deforestation, vis-à-vis supply chain approaches. Our findings indicate a greater need for research on: i) additional deforestation drivers beyond agriculture and economic factors; ii) the complex interactions between different drivers and deforestation control policies; iii) causes underlying deforestation in low or new deforestation areas; and iv) the dynamics between Amazonian subregions and countries. Better understanding of all deforestation drivers and the effectiveness of existing deforestation mitigation policies is a prerequisite for completely halting deforestation in Amazonia.
