RESUMO:

The current scenario of climate change and population growth in coastal areas has led to loss of habitat and ecosystem services (ES) for coastal populations. Currently there is little understanding about the effect of these changes on the distribution and value of these services in coastal environments. To understand the loss in the supply of coastal ES and their corresponding loss in economic values, in this thesis are being developed three chapters. The main objectives are (1) to map the bias of the most valued ecosystem services and environments in the world, as well as the distribution of economic benefits generated by them in relation to some indicators of human development (CH 1 - Global distribution and value of coastal-marine ecosystem services); (2) to evaluate the dynamics of carbon stock in mangrove areas over 18 years (CH 2- Dynamic and economic value of blue carbon service in mangroves areas); and (3) to model the vulnerability of the ES of coastal protection on a time scale and the future economic losses that would mean to the populations on the west coast of the South Atlantic (CAP 3- Effects of sea level rise on ecosystem services in coastal environments). The results obtained in chapter 1 indicate that a) the most quantified and valued ecosystems are wetlands and mangroves; b) the most valued services are recreation, commercial fishing and coastal protection; c) the most widely used valuation methods are willingness to pay and market values; d) The total annual average economic benefits of ES observed worldwide ranged from US $ 1,100 to US $ 87 billion; and (e) there is a positive relationship between economic values of the ES and the human development indicators (GDP and Human Development Index). The results obtained in chapter 2 indicate a decrease of 20.9% in the mangrove cover area and 22% in the mangrove carbon stocks in the northern region of the west coast of the South Atlantic, representing a loss of the carbon sequestration ES. The average net present value of the carbon sequestration ES in mangroves was USD$2,621.3.ha^-1, which represents an annual carbon stock value of USD$145.6.ha^-1. The analyzes in chapter 3 are underway and should be finalized in two months of sandwich PhD.
