Pathways to positive scenarios for the Amazon forest in Pará state, Brazil [Cam...
Siqueira-Gay, Juliana; Yanai, Aurora Miho; Lessmann, Janeth; Pessôa, Ana Carolina M.; Borja, Danilo; Canova, Moara Almeida; Borges, Rafael CabralInfrastructure projects and agriculture expansion are increasingly threatening forest conservation in Pará state (Brazil). It becomes necessary to address the implications of these activities on the Amazon complex socio-ecological system, considering both material and non-material aspects of Nature´s Contributions to People (NCP). Multiple studies developed future scenarios for the Amazon, but only a few have f...
Maintaining carbon stocks in extractive reserves in Brazilian Amazonia
Fearnside, Philip Martin; Nogueira, Euler Melo; Yanai, Aurora MihoExtractive reserves in the Amazon Forest maintain carbon stocks out of the atmosphere, thereby avoiding greenhouse-gas emissions that provoke global warming. This and other environmental services, such as recycling water and maintaining biodiversity, provide major reasons for creating these reserves and for according them priority in government programs. The importance of reducing carbon emissions from deforest...
Deforestation and Carbon Loss in Southwest Amazonia: Impact of Brazil’s Revised...
Roriz, Pedro Augusto Costa; Yanai, Aurora Miho; Fearnside, Philip MartinAbstract: In 2012 Brazil’s National Congress altered the country’s Forest Code, decreasing various environmental protections in the set of regulations governing forests. This suggests consequences in increased deforestation and emissions of greenhouse gases and in decreased protection of fragile ecosystems. To ascertain the effects, a simulation was run to the year 2025 for the municipality (county) of Boca do ...
Carbon stocks and losses to deforestation in protected areas in Brazilian Amazonia
Nogueira, Euler Melo; Yanai, Aurora Miho; Vasconcelos, Sumaia Saldanha de; Graça, Paulo Maurício Lima Alencastro de; Fearnside, Philip MartinBy 2014 approximately 2.2 million km2 (~43%) of Brazil’s Legal Amazonia region had been incorporated into an extensive network of 718 protected areas, which are comprised by 372 indigenous lands, 313 federal, state and municipal (county) conservation units, and 33 Maroon territories (Quilombos). Although protected areas occupy vast expanses in Amazonia, their importance as carbon reserves needs to be better und...
Deforestation and Carbon Stock Loss in Brazil’s Amazonian Settlements
Yanai, Aurora Miho; Nogueira, Euler Melo; Graça, Paulo Maurício Lima Alencastro de; Fearnside, Philip MartinWe estimate deforestation and the carbon stock in 2740 (82 %) of the 3325 settlements in Brazil’s Legal Amazonia region. Estimates are made both using available satellite data and a carbon map for the “pre-modern” period (prior to 1970). We used data from Brazil’s Project for Monitoring Deforestation in Amazonia updated through 2013 and from the Brazilian Biomes Deforestation Monitoring Project (PMDBBS) updated...
