“…Sin embargo, la mayoría de los estudios evaluaron iniciativas de conservación basadas solo en desincentivos. Dentro de este tipo de iniciativas, la efectividad de las ANP y/o sus áreas de amortiguamiento fue la que se evaluó con mayor frecuencia, considerando tanto sus efectos ambientales [27,31,36,[41][42][43], como los socioeconómicos [20,37]. Además de las fiscalizaciones de OSINFOR ya mencionadas, otra evaluación consideró la efectividad de las fiscalizaciones de OSINFOR en reducir la tala ilegal dentro de concesiones forestales con fines maderables en Loreto, Ucayali y Madre de Dios [44].…”

“…Similarly, many studies across the biome linked forest loss to roads, reflected by a distinctive fish-bone pattern of deforestation. In fact, accessibility to markets via roads was identified as an important underlying driver in the Amazon [74][75][76][77]. Infrastructure thus acts as a twofold driver, both proximate and underlying, and often dictates the pattern of deforestation.…”

“…This aligns with the classic net present value model of deforestation behavior (whereby land users are assumed to be motivated by differences in the discount flow of income they can get from different land uses). Studies in Peru [51,74], Bolivia [85,86], Ecuador [77,87] and Brazil [88,89] find that accessibility via roads and the resulting lowered transportation costs to local markets was associated with increased deforestation, especially due to pasture expansion and small-scale agriculture. Deforestation driven by local market access often spreads in a recognizable fishbone pattern from roads in less remote areas [90][91][92].…”

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.

“…For the case of the Amazon, Barber et al (2014) and Miranda et al (2016) find that PAs have mitigating effects on forest clearing in Brazil and Peru, respectively. Further, Pfaff et al (2015) find that PAs reduce deforestation in Brazil, correcting for the location bias (PAs are typically located in less-prone-to-deforestation areas), 6 and Aguirre et al (2021) find that natural PAs can help reduce deforestation in the presence of a growing road network in Peru. Distinguishing between strict versus mixed-use PAs, Blackman (2015) studies the Guatemala's Maya Biosphere Reserve, the largest park in the country, and finds that mixed-use PAs-which allow sustainable extractive activities-are more effective than strictly PAs, because of the operation of forest concessions.…”
