  Biodiversity contributes to the ecological and climatic stability of the Amazon Basin, but is increasingly threatened by deforestation and fire. Here we quantify these impacts over the past two decades using remote-sensing estimates of fire and deforestation and comprehensive range estimates of 11,514 plant species and 3,079 vertebrate species in the Amazon. Deforestation has led to large amounts of habitat loss, and fires further exacerbate this already substantial impact on Amazonian biodiversity. Since 2001, 103,079-189,755 km of Amazon rainforest has been impacted by fires, potentially impacting the ranges of 77.3-85.2% of species that are listed as threatened in this region. The impacts of fire on the ranges of species in Amazonia could be as high as 64%, and greater impacts are typically associated with species that have restricted ranges. We find close associations between forest policy, fire-impacted forest area and their potential impacts on biodiversity. In Brazil, forest policies that were initiated in the mid-2000s corresponded to reduced rates of burning. However, relaxed enforcement of these policies in 2019 has seemingly begun to reverse this trend: approximately 4,253-10,343 km of forest has been impacted by fire, leading to some of the most severe potential impacts on biodiversity since 2009. These results highlight the critical role of policy enforcement in the preservation of biodiversity in the Amazon.

  Abstract There has been significant study of barriers to implementation of payment for ecosystem services in Indigenous communities in less developed countries. These barriers include land tenure insecurity and lack of access to capital. However, there is no similar research in the Organization for Economic Cooperation and Development (OECD) countries. Our research fills this gap. We hypothesize that mismatches between the traditional land tenure regimes and institutional arrangements of Indigenous communities on one hand, and government sponsors of PES programs on the other hand, result in the lack of success of these programs. To test this hypothesis, we conducted a qualitative study of the Environmental Quality Incentives Program (EQIP) on the Hopi reservation in the United States. We answer two questions: (1) What barriers prevent Hopi ranchers and farmers from participating in incentive-based programs? (2) What institutional changes are necessary to permit Hopi farmer and rancher participation in EQIP? We analyzed primary documents and conducted key informant interviews. We conclude that land tenure is at the forefront of problems associated with administering PES programs in Indigenous communities. Without new approaches addressing the land tenure regimes in Indigenous communities, PES will continue to struggle on American Indian reservations and around the world.
