Abstract in Portuguese
Esta pesquisa consistiu em estimar o balanço de carbono da vegetação nativa de uma paisagem antropizada, ou seja, calcular a quantidade de biomassa arbórea acima do solo (AGB) preexistente (cenário pré-colonial), o quanto foi perdido pela ação humana (desmatamento e fragmentação) e que quantidade de carbono poderia ser recuperada com a adequação ao Novo Código Florestal Brasileiro (NCFB). Os fatores desse balanço são apresentados cartograficamente, e foram obtidos baseado em dados de campo para associar valores de tonelagem aos estoques estimados. A AGB pré-colonial estimada foi de 4.62 Gigatoneladas, dos quais 87.3% (3.85 Gt) foram perdidos até 2017. Essas perdas foram atribuídas em 90% (3.46 Gt) ao desmatamento, e 10% (0.39 Gt) à efeitos decorrentes da fragmentação. Os déficits em Reserva Legal e Áreas de Preservação Permanente estipulados pelo NCFB se traduzem em um potencial de recuperação de 0.11 Gt de AGB para São Paulo. Se reduzíssemos os efeitos da fragmentação esse potencial triplicaria (0.37 Gt). Os hotspots de biomassa atuais estão restritos às florestas costeiras (Ribeira do Iguape, Baixada Santista e Litoral Norte) e que as regiões com maior potencial de recuperação de carbono com a adequação ao NCFB são o Vale do Paraíba, Aguapeí e Pontal do Paranapanema. Finalmente, discutimos a eficácia dos mecanismos de compensação: seriam necessários 0.96 a 2.79 bilhões de US$ para restaurar o déficit legal de vegetação, possível apenas se os mercados estiverem dispostos a pagar pelo menos 17.5 US$ por tonelada de carbono fixado na vegetação

Abstract in English
The research aimed to estimate the carbon balance of natural vegetation in a tropical anthropized landscape. That is, to calculate the amount of pre-existing tree biomass above the soil (pre-colonial scenario), how much was lost by human action (deforestation and fragmentation) and how much carbon could be recovered with the adaptation to the New Brazilian Forest Code (NCFB). This balance is represented cartographically for the state of São Paulo, in its different stages (e.g. carbon inventory map for the original vegetation cover), and is based on field data to associate tonnage values with the estimated inventories. The estimated pre-colonial AGB for São Paulo was 4.62 Gigatonnes, of which 87.3% (3.85 Gt) were lost. These losses can be attributed to 90% (3.46 Gt) to deforestation, and 10% (0.39 Gt) to the effects of fragmentation. The vegetation deficits in Legal Reserve and Areas of Permanent Preservation stipulated by the NCFB translate into a potential recovery of 0.11 Gt of AGB. If we were to reduce degradation in forest fragments this potential AGB recovery would raise to 0.37 Gt. It was observed that current biomass hotspots are restricted to coastal forests (Ribeira do Iguape, Baixada Santista and Litoral Norte) and that the regions with the greatest potential for carbon recovery with adaptation to the NCFB are the Vale do Paraíba, Aguapeí and Pontal of Paranapanema. Finally, we discussed the effectiveness of compensation mechanisms, it would require 0.96 to 2.79 billion US$ to restore the legal deficit of vegetation, feasible as long as carbon markets are willing to pay 17.5 US$ for ton of fixed Carbon
