摘要：We assessed the impact on the Brazilian Amazon of a 2017 land law that reinforces a mechanism for
acquiring land rights historically linked to deforestation, since land grabbers clear the forest to signal
land occupation and claim land rights. In particular, we assessed two significant potential impacts:
(i) the loss of government revenue due to the sale of public land below market prices and (ii)the risk of
future deforestation and associated CO2 emissions in 19.6 million hectares allocated to expand land
privatization. The short-term revenue loss ranges from U$ 5 to 8 billion for 8.6 million hectares; the
future revenue loss ranges from U$ 16.7 to 23.8 billion for 19.6 million hectares; and between 1.1 and
1.6 million hectares would risk being deforested until 2027, which could emit 4.5–6.5 megatonnes of
CO2. The Brazilian government should review the decision about this area allocation; prioritize land
allocation for conservation and, if selling part of this area, charge market prices.
