SUMMARY:

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 drivers on the distribution and value of ES in coastal environments over time. In order to understand the dynamics of loss in the supplying of coastal ES and their corresponding loss in economic values, in this thesis we proposed to address these issues over three chapters. The main objectives were (1) to map the bias of the most valued coastal environments and ecosystem services in the world, as well as the distribution of economic benefits generated by them in relation to some indicators of human and socioeconomic development (CH 1 - Global Distribution and Value of Coastal-Marine Ecosystem Services); (2) to assess the effects of land conversions in a future period of 33 years, on the dynamics of Coastal Blue Carbon services provision by mangroves in Northeast Brazil (CH 2– Effects of Land Use Changes on Blue Carbon Services in Northeast Brazilian Mangrove Areas); and (3) evaluate the vulnerability and the temporal changes in coastal landscape by measuring the erosion/accretion rates in the shoreline and the economic losses and costs from long-term retreats in the coastline and mangroves loss in Northeast Brazil (CAP 3- Coastal Protection Service Delivery in Northeast Brazil in Face of Sea Level Rise). The results obtained in Chapter 1 indicate that a) the most quantified and valued coastal ecosystems worldwide are wetlands and mangroves; b) the most valued ES 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$77 billion; and (e) there is a positive relationship between the ES economic values and the human and socioeconomic development indicators (Gross Domestic Product and Human Development Index). The results obtained in Chapter 2 indicate that the forest area in northeastern Brazil can decrease by almost 35% and the total carbon stored by 22.2% by 2050, driven in large part by the expansion of salt and shrimp farming activities. The total Net Carbon Sequestration (NCS) could reach about 17.3 tCO2e/ha/year, and the Net Present Value (2017) is US $ 2,044.3/ha. Although there are apparently no major variations in the NCS values between periods over 33 years, high values of carbon emissions (1,351.2 tCO2e/ha) could be observed during 2017-2035. The results obtained in Chapter 2 indicate that one third of coastline is under erosion process and the prediction is of losing 630,000 m2 of shoreline until 2026. Mangroves reduce in 20% the moderate-high vulnerability levels of coastal areas from sea-level rise effects, while protecting a fourth part of the total exposed population. Probably this proportion could increase to half the population if total mangrove area were lost, causing costs of more than USD6.1billions (BRL32.4 billions).
