RESUMO:

Although the transition between the Cerrado and Amazon biomes is described as the most extensive ecotonal region between savannah and forest in the world, little is known about the ecosystem services its natural ecosystems provide. Also, it still needs to be discovered how much intense anthropogenic activities and rapid changes in land use coverage have affected these services and transformed this scenario over the last three decades. The present study aims to evaluate the carbon stock of the aerial part of the typical savannah vegetation that occurs in the transition between the Cerrado and Amazon biomes, estimate its financial value, evaluate the change in land use and cover and its impact on the loss of services and identify areas with potential for implementing payment for ecosystem services. For this, we used data from Mapbiomas collection 6 to generate a manually categorized vegetation map and estimate how many hectares of typical savannah formations exist in the transition. From the extrapolation of the average carbon stored in a set of field plots composed of typical cerrado, we estimated the potential of the savannah formations of the transition to accumulate carbon. For the valuation of carbon, we adopted an average price in dollars practiced per ton of carbon equivalent (U$/tCO2eq), assigned by the global carbon market, based on the Brazilian Carbon Pricing platform. We also evaluated the feasibility of the proposed official carbon database for Brazilian vegetation in estimating the carbon stock of the transition savannah formations.
