TITLE:

SUMMARY:

Occurring between the land-sea strips, the mangrove ecosystem plays important roles in the absorption and storage of , in maintaining biodiversity, filtering water and controlling coastal erosion. Despite such relevance, this ecosystem has been pointed out as one of the most impacted, especially due to climatic events and historical economic exploitation on the coast. Considering this, there is a demand for research that expands the dialogue aimed at the environmental quality of the mangrove from the identification, quantification, fragmentation, density, carbon sequestration and valuation of the mangrove. Therefore, the objective of this research is to evaluate the mangrove that integrates the Piranhas-Açu/RN River Estuary Complex, identifying its spatial distribution, its metric and density patterns, as well as the potential for atmospheric carbon sequestration, and the monetary value of its mangrove vegetation, as indicators of ecosystem conservation. As methodological procedures, the following steps were followed: 1) Bibliographic survey; 2) Identification of mangrove in 2008 and 2021; 3) Application of landscape metrics in mangrove fragments from both years; 4) Based on the 2021 mangrove fragments, the following indexes were calculated: Normalized Difference Vegetation Index (NDVI), Photochemical Reflectance Index (PRI), sPRI, and the flux index; and 5) Based on the mangrove fragments from 2008 and 2021, the monetary estimate of the mangrove will be made. So far, the introduction, theoretical foundation, presentation of the study area, methodology, as well as the following results were carried out: 1. Multitemporal mapping of the mangrove; 2. Landscape metrics in mangrove fragments; 3. Estimate of mangrove density and its potential for carbon sequestration. However, the chapter on the valuation of mangrove fragments will still be elaborated, as well as the final considerations of the dissertation.
